DESC: METHOD AND SYSTEM FOR AUTOMATIC SWITCHING OF LUMINOUS DEVICE SECURED ONTO A VEHICLE CABIN ROOF
FIELD OF INVENTION
[001] The present disclosure described herein, in general, relates to a method and a system for automatic switching of a luminous device secured onto a vehicle cabin roof. The present subject matter, in particular, relates to a method and a system for automatic switching of a luminous device secured onto a vehicle cabin roof by just opening and closing of the cabin door.
BACKGROUND
[002] The background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication specifically or implicitly referenced is prior art.
[003] In the present scenario, operators working in mines are exposed to a very dusty and blur environment which causes poor visibility. At night the visibility gets worse due to the darkness. In such conditions of poor visibility, the operators find it difficult to locate and switch ON the luminous device of their heavy-duty vehicle cabin or off-highway equipment wherein the luminous device is secured to the cabin roof as the existing the luminous device to be switched ON/OFF manually. In the effort of locating the switch, there are chances that the operators may get hurt or take more time. Although, there are vehicles having systems wherein the luminous device of the vehicle cabin switches ON automatically by using contact-type sensors, however, the switching OFF these luminous devices still requires manual effort and it is not suitable to install such systems in the heavy-duty vehicle or off-highway equipment. The systems are only suitable for light-duty vehicles.
[004] In view of the above, there is a need to provide a system that performs the function of automatically switching ON/OFF of the luminous device secured onto the vehicle cabin roof and which can be installed in a heavy-duty vehicle.
[005] The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgment or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

[0025] As already discussed in the background the operators working in mines are exposed to a very dusty and blur environment which causes poor visibility. At night the visibility gets worse due to the darkness. The operators find it difficult to locate and switch ON the luminous device of their heavy-duty vehicle or off-highway equipment cabin wherein the luminous device is secured to the roof of the cabin because the device needs to be switched ON/OFF manually in the dusty environment which also pose a risk of injury to the operator. It is known from the light-duty vehicles wherein a system can automatically switch ON the luminous device of the cabin roof by using contact-type sensors but requires manual effort to be switched OFF. The system moreover cannot be installed in off-highway equipment or heavy-duty vehicle because of high vibration operation, the structure of the cabin and also the cabin of such vehicles is enveloped by rollover protection (ROP) structure. Therefore, there is a need to provide a system that performs the function of automatically switching ON/OFF the luminous device of the vehicle cabin and can be installed in a heavy-duty vehicle as well.
[0026] Accordingly, Fig. 1 shows the block diagram 100 of the circuit of the system for automatic switching ON/OFF of a luminous device 102 secured to the roof of a vehicle cabin in accordance with the present disclosure. The circuit comprises a plurality of proximity sensors for sensing the position of the vehicle cabin door. In a preferred embodiment, two proximity sensors 104 and 106 are employed for sensing the pre-defined position of the vehicle cabin door on which a metal target is placed for actuating the proximity sensors 104 and 106. The proximity sensor 104 and 106 are being used for sensing an opened/ closed position of the cabin door. The proximity sensors can be of any type; inductive, capacitive, optical, magnetic, ultrasonic, etc. In a preferred embodiment, the proximity sensors 104, 106 used are of inductive type.
[0027] The circuit further comprises a logic control unit 108. In a preferred embodiment, the logic control unit 108 is an SPST relay. The logic control unit 108 is connected to a power supply 110 which will energize or de-energize the logic control unit 108 as per the signal received from the proximity sensors 104 and 106. The power supply 110 provides a current of 10A. The energization or de-energization of the logic control unit 108 closes or opens a switch 112 respectively. The switch 112 is connected to the logic control unit 108. The closing and opening of the switch 112 will result in switch ON/OFF the luminous device 102. The luminous device 102 is connected with the switch 112. In an embodiment, the luminous device 102 can be but not limited to an incandescent bulb, LED bulb, roof lamp, etc. The system is fitted in the console of a cabin.
[0028] Fig. 2 illustrates a flow chart 200 of a method for automatic switching ON/OFF of a luminous device secured onto a vehicle cabin roof in accordance with the present disclosure. The method comprises the steps of transmitting signals, from a plurality of proximity sensors (104, 106) to a logic control unit (108) based on the pre-defined position of a vehicle cabin door as represented by bock 202. The method is followed by sending signals, by the logic control unit (108) to the luminous device (102) for switching ON/OFF the luminous device (102) represented by block 204. The proximity sensor 104 and 106 in the method are being used for sensing an opened/ closed position of the cabin door. The proximity sensors can be of any type; inductive, capacitive, optical, magnetic, ultrasonic, etc. In a preferred embodiment, the proximity sensors 104, 106 used are of inductive type. In a preferred embodiment, the logic control unit 108 is an SPST relay. The logic control unit 108 is connected to a power supply 110 which will energize or de-energize the logic control unit 108 as per the signal received from the proximity sensors 104 and 106. The power supply 110 provides a current of 10A. The energization or de-energization of the logic control unit 108 closes or opens a switch 112 respectively. The switch 112 is connected to the logic control unit 108. The closing and opening of the switch 112 will result in switch ON/OFF the luminous device 102. The luminous device 102 is connected with the switch 112. In an embodiment, the luminous device 102 can be but not limited to an incandescent bulb, LED bulb, roof lamp, etc.
Working of the system when the luminous device is to be switched ON
[0029] When an operator opens the cabin door, the metal target placed on the cabin door gets away from proximity to the proximity sensor 104 or 106 and actuates it. The proximity sensor 104 or 106 then sends a signal about the opening of the cabin door to the logic control unit 108. Upon receiving the signal about the open position of the cabin door, the logic control unit 108 gets energized by the power supply 110 and ground signal from the proximity sensor 104 or 106, thus closing the circuit and thereby switching ON or illuminating the luminous device 102.
Working of the system when the luminous device is to be switched OFF
[0030] When the operator closes the cabin door the metal target paced on the cabin door gets in proximity to the proximity sensor 104 or 106 and actuates it. The proximity sensor 104 or 106 then sends a signal about the closing of the cabin door to the logic control unit 108. Upon receiving the signal about the closed position of the cabin door, the logic control unit 108 gets de-energized by removal of ground from the proximity sensor 104 and 106 with power supply 110, thus opening the circuit and thereby switching OFF the luminous device 102.
Technical Advantages
[0031] The present disclosure thus provides switching of the luminous device without any manual effort for locating the switch which results in providing comfort and ease to the operator and avoids chances of injury.
[0032] The present disclosure is not only suitable for heavy-duty vehicles but for light-duty vehicles as well. The present disclosed system is simple, reliable and cost-effective.
[0033] The present disclosed system involves non-contact type sensor intelligence which is easily capable of sensing the open/closed position of the heavy-duty vehicle cabin doors which are subjected to high vibration operation and with the cabin being enveloped by rollover protection (ROP) structure.
[0034] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation, no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to “at least one of A, B, or C, etc.” is used, in general, such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
[0035] Although embodiments for the present subject matter have been described in language specific to structural features, it is to be understood that the present subject matter is not necessarily limited to the specific features described. Rather, the specific features and methods are disclosed as embodiments for the present subject matter. Numerous modifications and adaptations of the system/component of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the scope of the present subject matter.
