[0006]
Therefore, the present invention provides a test method for an elevator door-opening running protection device and an elevator door-opening running protection device that can shorten the test time.
Means to solve the problem
[0007]
In order to solve the above problems, in the test method according to the present invention of the door open running protection device of the elevator for confirming the operation of the door opening running protection device provided in the elevator system, maintenance operation and the landing position of the elevator are intentionally set.

Embodiment for carrying out the invention
[0012]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each figure, those having the same reference number indicate the same configuration requirement or the configuration requirement having similar functions.
[0013]
FIG. 1 is an overall configuration diagram of an elevator system according to an embodiment of the present invention. As described below, this elevator system is equipped with a door-open running protection device, and a test for confirming the operation is performed on the door-open running protection device.
[0014]
As shown in FIG. 1, a car 100 that moves between a plurality of floors in a hoistway formed in a building is connected to a counterweight weight 111 via a main rope 101. The main rope 101 is wound around a rope wheel 103 and a warp wheel 104 that are mechanically connected to the rotating shaft of the electric motor 105. As a result, the car 100 and the counterweight weight 111 are suspended by the main rope 101 in the hoistway.
[0015]
When the main rope 101 is driven by the rotary drive of the rope wheel 103 by the electric motor 105, the car 100 and the counterweight weight 111 move in the hoistway in opposite directions. The electric motor 105 (for example, a permanent magnet synchronous electric motor) is driven by the electric power supplied by the power converter 107 (for example, an inverter device), and is braked by the braking device 102 when the car 100 is stopped.
[0016]
Further, the encoder 106, which is a pulse generator attached to the electric motor 105, generates a pulse signal according to the rotation of the electric motor. By counting this pulse signal, the elevator control device 108 calculates the speed of the electric motor 105, the position of the car 100 in the hoistway movement direction, the movement distance, and the like. Then, the elevator control device 108 controls the operation of the car 100 by controlling the electric motor 105 by the power converter 107 based on the calculation result. The car 100 is provided with a car door 110, which is a car side door that engages with the landing door 109, which is a landing side door, and opens and closes together with the landing door 109.
[0017]
The UCMP control device 1 is a control device having a door-open running protection function, and controls braking of the car 100 by braking operation and power cutoff independently of the elevator control device 108. The UCMP control device 1 has a CPU (Central Processing Unit) that executes processing as a main component, and has a door-open running protection function when the CPU executes a predetermined program. Although the elevator control device 108 also includes a CPU, the CPU of the UCMP control device 1 and the CPU of the elevator control device 108 are independent CPUs.
[0018]
The UCMP control device 1 inputs signals from the position sensor 2, the car door switch 4 that detects the opening / closing of the car door 110, and the landing door switch 5 that detects the opening / closing of the landing door 109, and is based on these signals. When it is determined that the car 100 is located in the hoistway at a position separated from the landing by a specific distance or more, and one of the car door 110 and the plurality of landing doors 109 is in the open state, that is, the car 100 Is determined to be in the door open running state, and outputs an operation command of the brake device 102 and a power cutoff command of the power converter 107.
[0019]
Here, the specific distance is the distance in the vertical direction from the landing floor surface (reference landing position) where the car 100 is allowed to move in the open state.
[0020]
Such a specific distance is such that when the car door 110 and the landing door 109 start to move in an open state, the height of the opening of the car room seen from the landing is pinched and the height required for prevention can be secured. In addition, the height of the gap created at the bottom of the floor of the car is set so that the height required to prevent falling into the hoistway can be secured.
[0021]
The position sensor 2 detects that the car 100 is located within a range of a specific distance by detecting the object to be detected 3 provided in the car 100 and fixedly installed in the hoistway. .. The specific distance is set within the range of positions where the door opening operation is possible in the hoistway (hereinafter referred to as "door zone"). In the door zone, the car door 110 and the landing door 109 are engaged by an engaging device, provided in the car 100, and the car door 110 is driven by a door drive device (not shown) controlled by the elevator control device 108. Then, both the car door 110 and the landing door 109 are opened and closed.
[0022]
The door zone is also considered in normal operation control. In normal operation control, the elevator control device 108 causes the car 100 to land and stop on the stop floor when the position sensor 2 detects that the traveling car 100 has entered the door zone of the stop floor. As described above, the electric motor 105 is controlled by the power converter 107.
[0023]
As the position sensor 2, a non-contact type detection sensor such as a photoelectric type, a magnetic type (magnet type, high frequency magnetic field type, etc.) and a electrostatic capacity type can be applied. In the present embodiment, if the range of the specific distance and the door zone match, the position sensor 2 can be used for both the door open traveling determination and the normal operation control. As a result, the number of parts can be reduced. Further, even when the range of the specific distance and the door zone match, the position sensor 2 may be dedicated to the door open running determination and another position sensor may be provided for operation control. In this case, the reliability of the safety system is improved.
[0024]
If the specific distance is different from the door opening allowance zone, a specific distance sensing device will be installed in the car in addition to the position sensor used for normal operation control. As the specific distance sensing device, for example, a non-contact detection sensor similar to the position sensor 2 can be applied. In this case, in this embodiment, the specific distance sensing device is connected to the UCMP control device 1 instead of the position sensor 2. The position sensor may be provided with a specific distance sensing function in addition to the door opening permissible zone sensing function.
[0025]
The brake operation command output by the UCMP control device 1 is a command signal for operating the brake device 102, shuts off the power supplied to the brake device 102, generates a braking force in the brake device 102, and causes the car 100 to operate. To brake. Further, the power cutoff command output by the UCMP control device 1 is a command signal for shutting off the power supply of the power converter 107, and stops the power supply to the power converter 107 to stop the electric motor 105. As a result, the car 100 is braked and stopped, and the stopped state is maintained.
[0026]
During normal operation, the elevator control device 108 controls the power converter 107 and the brake device 102 to control the operation of the car 100, but when the door open running is detected, the UCMP control device 1 brakes. It controls the operation and power cutoff to brake and stop the car 100.
[0027]
When the test for confirming the operation of the door open running protection device including the UCMP control device 1, the car door switch 4, the plurality of landing door switches 5, the position sensor 2 and the detected object 3 as described above is executed, The maintenance device 50 is electrically communicably connected to the UCMP control device 1 and the elevator control device 108. The maintenance device 50 is composed of a portable computer or a terminal device, acquires operation data of the elevator device, determines the state of the elevator device, and operates a car during maintenance and inspection. In the present embodiment, the maintenance device 50 is carried into the installation location of the elevator to be maintained and used by a maintenance engineer in a series of maintenance test operations.
[0028]
At the time of testing the door-open running protection device, first, the maintenance device 50 is electrically communicably connected to the UCMP control device 1 and the elevator control device 108, and is electrically connected to the elevator control device 108. Operate a specific switch in group 60 (SW) to set the normal operation mode. Switch from operation to maintenance operation. Thereby, the maintenance device 50 can operate the low-speed operation and stop of the car and the opening / closing drive of the car door 110.
[0029]
By the operation by the maintenance device 50, the car 100 that has stopped landing is moved to a position where the re-floor alignment operation is effective. Here, in the re-floor alignment operation, the elevator control device 108 detects a step between the floor surface of the car 100 and the floor surface of the landing 115 when the landing of the car 100 is stopped, and is equal to or higher than a predetermined value. If there is a step, drive the car 100 so as to eliminate the step and stop the landing again.
[0030]
The re-floor alignment operation is executed during the normal operation, but during the maintenance operation, the re-floor alignment operation is invalidated in the elevator control device 108. During the test of the door-open running protection device, the UCMP control device 1 enables the re-floor alignment operation. Therefore, by switching the operation mode switched by the maintenance device 50 from the maintenance operation to the normal operation, the automatic re-floor alignment operation is executed.
[0031]
After the car has moved to a position where the re-floor alignment operation is effective, when a door open / close command signal is output from the maintenance device 50 to the elevator control device 108 by the operation of the maintenance engineer, the car door 110 and the landing door on the stop floor are output. 109 is closed. Here, the car 100 is in a state of waiting for a test operation including an automatic re-floor alignment operation for testing the door-open traveling protection device.
[0032]
When the soft / hard protector is released by the maintenance engineer while waiting for the test operation of the car 100, the UCMP control device 1 switches the operation mode from the normal mode to the test mode. In the test mode, the door open simulation unit 10 in the UCMP control device 1 sets the door open detection state regardless of the door open / closed state detection signals of the car door switch 4 and the landing door switch 5. In the present embodiment, the door open simulation unit 10 cuts off the door closed state detection signal of the car door switch 4 and the landing door switch 5. As a result, the UCMP control device 1 determines that the car door 110 and the landing door 109 are open even if the car door 110 and the landing door 109 are closed. At the same time, the UCMP control device 1 outputs a power cutoff command for cutting off the power supply of the power converter 107. At this time, the operation command to the brake device 102 is valid.
[0033]
When the operation mode of the UCMP control device 1 becomes the test mode, a re-floor alignment operation command is given by switching the maintenance operation mode set by the maintenance device 50 to the normal operation mode, whereby the door is opened with the door closed. A test of the travel protection device is performed. In this test, first, the elevator control device 108 performs an automatic re-floor alignment operation.
[0034]
At this time, since the UCMP control device 1 outputs a power cutoff command and at the same time does not output a brake operation command, the brake device 102 is in an open state and the electric motor 105 does not generate torque. Therefore, the car 100 immediately rides. The rope wheel 103 rotates due to the unbalanced torque due to the weight difference between the basket 100 and the counterweight weight 111. As a result, the car 100 moves in the ascending (descending) direction from the landing position. Since the door open detection state is set by the door open simulation unit 10, the UCMP control device 1 determines that the door is open, and the car 100 is determined based on the position detection signal from the position sensor 2. When it is determined that the position of the vehicle is separated from the landing by a specific distance or more, that is, when it is determined that the car 100 is in the door open traveling state, a brake operation command is output. As a result, the car 100 is braked and stopped by the braking device 102.
[0035]
When the maintenance engineer confirms that the car 100 is stopped by the maintenance device 50, the landing door 109 is opened and the distance between the floor surface of the landing 115 and the floor surface of the car 100, that is, the braking distance (FIG. 4) is measured. And check if the measured value is within the specified allowable range.
[0036]
Next, the test method of the door-open running protection device in the present embodiment will be described.
[0037]
FIG. 2 is a flowchart showing a test method of the door open running protection device in the present embodiment. Further, FIG. 3 is a flowchart showing steps between AB in the flowchart of FIG. 2.
[0038]
Each step in FIGS. 2 and 3 is performed by one of a maintenance engineer, a maintenance device 50, an elevator control device 108, and a UCMP control device 1. The step surrounded by the broken line in FIG. 2 is a software process, and is mainly executed by the UCMP control device 1.
[0039]
Before the test of the door-open running protection device by the test method shown in FIGS. 2 and 3 is executed, the maintenance engineer operates a specific switch in the maintenance switch group 60 (SW) to operate the operation mode normally. Switch to maintenance operation.
[0040]
First, in step S10, the maintenance engineer operates the maintenance device 50 to drive the car, and moves the car 100 to a position where the re-floor alignment operation is effectively executed.
[0041]
Next, in step S20, the maintenance engineer operates the maintenance device 50 to drive the door drive device and close the landing and the car door.
[0042]
Next, in step S30, the maintenance engineer visually confirms whether the landing and the car door are closed. If the landing and the car door are closed, then step S40 is executed, and if not closed, step S20 is executed again. The maintenance device 50 may acquire the operating states of the landing door switch 5 and the car door switch 4 from the elevator control device 108, and the acquired operating states may be confirmed on the display device of the maintenance device 50.
[0043]
In step S40, the maintenance engineer releases the soft protector. When step S40 is executed, then step S50 is executed.
[0044]
In step S50, the maintenance engineer releases the hard protector.
[0045]
Here, the soft protector and the hard protector are functions that protect the operation of the UCMP control device 1 in terms of hardware and software, respectively, so that the operation mode of the UCMP control device 1 does not switch to the test mode during normal operation. This is a function provided in the control device 1.
[0046]
The release of the soft protector is executed by a maintenance engineer operating a dip switch provided on the control panel in which the elevator control device 108 is stored or operating the maintenance device 50.
[0047]
To release the hard protector, a maintenance engineer operates a short connector or hard switch provided on the control panel, or operates a short connector or hard switch (“70” in FIG. 1) provided on the landing. Is executed by.
[0048]
When the soft protector is released, the soft protector release signal is transmitted to the UCMP control device 1. When the hard protector is released, the hard protector release signal is transmitted to the UCMP control device 1.
[0049]
When step S50 is executed and the UCMP control device 1 receives the soft protector release signal and the hard protector release signal, the flow of the test method shown in FIG. 2 shifts to the "software process" executed by the UCMP control device 1. In the following description of the "software process" (steps S60 to S67), the main body that executes the process is the UCMP control device 1 unless otherwise specified.
[0050]
In the "software process", first, in step S60 (FIG. 2), it is determined whether both the soft protector and the hard protector are properly released based on the release data represented by each of the received release signals. If it is determined that both the soft protector and the hard protector are properly released (Yes in step S60), then step S61 (FIG. 3) is executed, and the soft protector and the hard protector are not properly released. If it is determined (No in step S60), a series of processes is terminated.
[0051]
Here, in the test method shown in FIG. 2, after the soft protector is released, the hard protector is released (steps S40 and S50). This prevents the soft protector from being erroneously released before the maintenance engineer operates the switch when the hard protector is released, and the operation mode of the UCMP control device 1 is prevented from switching to the test mode. Therefore, in step S60, when it is determined that both the soft protector and the hard protector are released, the hard protector is released after the soft protector is released based on the receiving order of the soft protector release signal and the hard protector release signal. Judge whether or not. Then, when it is determined that the hard protector is released after the soft protector is released, it is determined that both the soft protector and the hard protector are properly released as described above. Also, if it is determined that the hard protector has not been released after the soft protector has been released, and if it is determined that one or both of the soft protector and the hard protector have not been released, the soft protector is determined as described above. It is determined that the protector and the hard protector are not properly released.
[0052]
If the UCMP control device 1 determines in step S60 that the soft protector and the hard protector are not properly released, the UCMP control device 1 may output a notification signal indicating that the protector is not properly released. In this case, when the notification signal is received by the maintenance device 50, the maintenance engineer can confirm that either or both protectors are not properly released via the maintenance device 50.
[0053]
When both the soft protector and the hard protector are properly released in step S60, steps S61 to S67 shown in FIG. 3 are sequentially executed as software processing.
[0054]
In step S61, the re-floor alignment operation by the elevator control device 108 is enabled. That is, the UCMP control device 1 transmits a command signal for enabling the re-bed alignment operation to the elevator control device 108.
[0055]
Next, in step S62, the door open simulation unit 10 included in the UCMP control device 1 simulates the door open state detected by the car door switch 4 and the landing door switch in the UCMP control device 1 during normal operation. To.
[0056]
Next, in step S63, the test mode is enabled in the UCMP control device 1. For example, the setting of the flag indicating valid / invalid of the test mode is changed from invalid (for example, flag = 0) to valid (for example, flag = 1).
[0057]
Next, in step S64, it is determined whether the test mode is valid by executing step S63. For example, it is determined whether or not the flag indicating whether the test mode is valid or invalid is set to be valid. If the test mode is valid (Yes in step S64), then step S65 is executed, and if the test mode is not valid (No in step S64), step S63 is executed again.
[0058]
In step S65, the re-floor alignment operation execution permission signal for instructing the elevator control device 108 to execute the re-floor alignment operation is activated in the elevator control device 108. That is, the UCMP control device 1 transmits a command signal for validating the re-bed alignment operation execution permission signal in the elevator control device 108 to the elevator control device 108. As a result, when the elevator control device 108 receives the re-floor alignment operation execution permission signal, the re-floor alignment operation is executed without invalidating this signal.
[0059]
Next, in step S66, the UCMP control device 1 enables the transmission of the brake operation permission signal by the own device. As a result, the UCMP control device 1 is tested.When the door open running state is determined in the test mode, a brake operation permission signal is transmitted to put the brake device 102 in the braking state.
[0060]
Next, in step S67, the UCMP control device 1 invalidates the transmission of the motor operation permission signal by the own device. As a result, the UCMP control device 1 outputs a power cutoff command and cuts off the power supply to the electric motor 105 when the re-bed alignment operation (step S70) described later is executed in the test mode.
[0061]
When step S67 is executed, step S70 (FIG. 2) is executed next. Regarding S70 to 100, the work by the maintenance engineer and the operation by the UCMP control device 1 are mixed.
[0062]
In step S70, the maintenance engineer operates the maintenance device 50, and the maintenance device 50 transmits the re-floor alignment operation execution permission signal to the elevator control device 108. As a result, a test (UCMP test) of the door-open running protection device including the execution of the automatic re-floor alignment operation is executed.
[0063]
In the UCMP test, first, when the elevator control device 108 receives the re-floor alignment operation execution permission signal, the automatic re-floor alignment operation of the car 100 is executed. At this time, the car door 110 and the landing door 109 are closed by the execution of step S20. The vehicle 100 is in an open state by the automatic re-floor alignment operation command, and the electric motor 105 is in a state where it can be free-run without generating torque. As a result, the rope wheel 103 rotates due to the unbalanced torque caused by the weight difference between the car 100 and the counterweight 111, so that the car moves in the ascending (descending) direction in the hoistway with the door closed. .. Then, when the car 100 moves out of the range of the specific distance, the UCMP control device 1 determines that the car is in the door open running state because the door open detection state is set in a simulated manner, and the brake is activated. Output a command signal. As a result, the braking device 102 is in the braking state, and the car 100 is braked and stopped.
[0064]
Next, in step S80, the maintenance engineer and the UCMP control device 1 acquire the operating state of the car from the elevator control device 108 by the maintenance device 50, and the car 100 is stopped based on the acquired operating state. By determining whether or not the UCMP test has been completed. When the maintenance engineer and the UCMP control device 1 determine that the UCMP test has been completed (Yes in step S80), the maintenance engineer and the UCMP control device 1 then execute step S90. Further, when the maintenance engineer or the UCMP control device 1 determines that the UCMP test has not been completed (No in step S80), the maintenance device 50 continues to check the operating state of the car. That is, in this case, the operation of the car in the UCMP test (S70) is continued.
[0065]
When the maintenance engineer and the UCMP control device 1 confirm that the car 100 is stopped, that is, the end of the UCMP test is confirmed in step S80, the operation mode of the UCMP control device 1 is returned from the test mode to the normal mode in steps S90 and S100. Execute the process to make it.
[0066]
In step S90, the UCMP control device 1 cancels the simulated setting of the door open detection state. Further, in step S100, the maintenance engineer and the UCMP control device 1 invalidate various settings (steps S65 to S67) in the test mode in the UCMP control device 1 by operating the maintenance device 50 or the like.
[0067]
When steps S90 and S100 are executed and the operation mode of the UCMP control device 1 is returned from the test mode to the normal mode, a series of processes in the test method of the door open running protection device shown in FIGS. 2 and 3 is completed. After that, the maintenance engineer measures the braking distance of the stopped car 100 in order to evaluate the test result.
[0068]
FIG. 4 is a front view of the landing door 109 and the car 100 as seen from the landing side during the UCMP test and the braking distance measurement.
[0069]
As shown in the upper figure of FIG. 4, during the UCMP test, the landing door 109 is closed, and the landing is not exposed in the hoistway or in the moving car 100. This ensures a high degree of safety for test work at the landing.
[0070]
As shown in the lower figure of FIG. 4, when measuring the braking distance, the maintenance engineer opens the landing door 109 and measures the distance between the car floor surface and the landing floor surface as the braking distance L. It should be noted that each door does not have to be fully opened as long as the braking distance L can be measured.
[0071]
As described above, according to the present embodiment, when confirming the operation of the door-open running protection device, the re-floor alignment operation by the elevator control device is enabled to execute the automatic re-floor alignment operation, and the unbalanced torque is used. Since the car is moved, the time required to move the car can be shortened. Further, since the door open state is set in a simulated manner, the car door and the landing door can be closed when the car is moved by the automatic re-floor alignment operation and the unbalanced torque. Therefore, the safety of the test work is improved, and the time required for safety measures can be shortened. As a result, the time required for the operation test of the door-open running protection device can be shortened.
[0072]
In addition, the control device of the door-open running protection device performs a test operation in response to the release of the soft protector and hard protect that prevents the door-open running protection device from performing a test operation during normal operation, so various functions for checking the operation are performed. Is automatically enabled and set. As a result, the time required for the operation test of the door open running protection device can be shortened. Further, by releasing the hard protector after releasing the soft protector, it is possible to prevent erroneous transition to the test mode during normal operation or the protector release operation.
[0073]
In addition, by operating the maintenance device to execute the re-floor alignment operation, or by releasing the protector by the maintenance device or the release means installed at the landing, the test work at the landing becomes possible.
[0074]
The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations. Further, it is possible to add / delete / replace a part of the configuration of the embodiment with another configuration.
[0075]
For example, the elevator may have a machine room or may be a so-called machine room-less elevator.
[0076]
Also, the number of floors of the building where the elevator is installed may be arbitrary. Therefore, the number of landing doors may be as many as any number of floors.
