5 without manual intervene and easiness of replenishment.

BACKGROUND OF THE INVENTION
[02] Gas cylinders are used in most households and industries for providing gas to burner meant for cooking or heating. Since years, a lot of life hazards are reported
10 because of gas cylinder leakages and hence known systems are provided that monitors the gas cylinders and avoid such mishaps. Another challenge with the gas cylinder is replenishment of the gas cylinder. Currently, when the gas cylinder is completely exhausted, then a replenishment request is manually done with a gas cylinder vendor by a user. As there is manual involvement for generating the replenishment request, it
15 is likely that the user may forget to make the replenishment request delaying in timely replenishment. It is also observed that when the replenished gas cylinder is arrived, many a times, there is pilferage of gas which is not noticeable at the arrival.

[03] Cylinder weight measurement systems are known in the prior art, for example
20 from patent document US6284987B1 discloses an embedded weighing scale that detects and indicates changes in a small weight that is embedded within a much larger residual weight and also provides a potentiometer that provides an electrical signal to an alarm device to warn the consumer that the weight of a consumable quantity has dropped into the critical weight range. Further, the patent document US5261268
25 discloses a gas leak detection system in which a flow sensor is used for detecting the amount of gas flowing through a gas flow passage.

[04] However, none of the known gas cylinder systems provide a facility to switch- off the gas regulator and main electricity supply line in event of gas leakage without
30 manual intervene, notify, without manual intervene, the user in event of gas leakage and replenish the gas cylinder before getting fully consumed. Further, the known

systems sense gas flowing through a gas flow passage of the gas cylinder and hence does not sense gas in the surrounding area of the gas cylinder. The known systems also measures weight of the gas cylinder, however, based on the gas cylinder weight may not initiate an order for replenishment. The known systems also do not help to
5 know that whether there was any gas theft or pilferage before the delivery.

OBJECTS OF THE INVENTION
[05] Some of the objects of the arrangement of the present disclosure are aimed to ameliorate one or more problems of the prior art or to at least provide a useful
10 alternative and are listed herein below.

A principle object of the present disclosure is to provide a system for controlling and managing a gas cylinder that provides monitoring, regulating in event of leakage and ordering replenishment resulting in holistic control and management of the gas
15 cylinder without manual intervene resulting is provision of safety and convenience to users.

20 cylinder without the need of manual intervene.

Still another object of the present disclosure is to provide a system for controlling and managing a gas cylinder that is capable to turn-off a main electric supply line in event of gas leakage without any manual intervene.
25
Yet another object of the present disclosure is to provide a system for controlling and managing a gas cylinder that is capable to order for replenishment of gas cylinder before the existing gas cylinder in use is fully consumed.

Another object of the present disclosure is to provide a system for controlling and managing a gas cylinder that monitors the weight of gas cylinder at arrival to understand whether there is pilferage of gas.

[10] Moreover, in the present disclosure, rather than providing only gas sensing or only weight measuring, the controlling and monitoring facilitates multiple features monitoring, regulating in event of leakage and ordering replenishment using interconnected components that communicates with each other to provide safety and
10 management at ease.

[11] Referring now to the drawings, Figures 1 to 7, where the present invention is generally referred to with numeral (100), it can be observed that a system (100) for controlling and managing a gas cylinder (05), in accordance with an embodiment, is
15 provided which includes a weighing unit (10), a regulator knob actuation unit (20), a gas sensor (30) and a control unit (40).

[12] The weighing unit (10) is positioned on a flat surface (11), typically on the ground. The weighing unit (10) is to be positioned with the gas cylinder (05) thereon.
20 The weighing unit (10) continuously monitors the weight of the gas cylinder (05). The weighing unit (10) is powered by a power source (12). The power source (12) can be a power storage battery which can be integral with the weighing unit or can be a separate storage battery connected via a wire connection or can be a power socket connected to the weighing unit (10) by a wire connection.
25
[13] The regulator knob actuation unit (20) is defined with a clamp (21), a regulator-knob holder (22) and a driver (23). The clamp (21) facilitates clamping and unclamping of the regulator knob actuation unit (20) with the gas cylinder (05) such that the regulator knob actuation unit (20) is mounted and removed from the gas
30 cylinder (05). The clamp (21) includes a clamp portion (21a) and a clamping knob

(21b) which when rotated in one direction facilitates the clamp portion (21a) to be connected with the gas cylinder (05) and when rotated in other/opposite direction facilitates removal of the regulator knob actuation unit (20) with the gas cylinder (05). In the illustrated example, the clamp portion (21a) is connected to the vertical support
5 (07) of the gas cylinder (05). The regulator-knob holder (22) is clamped with the regulator-knob (06) of the gas cylinder (05). The regulator-knob holder (22) includes a holding portion (22a) and an adjustable handle (22b) which can be telescopic rod. In one embodiment, the holding portion (22a) is made of polymeric material which can be flexible or rigid. The driver (23) is in connection with the regulator-knob holder
10 (22) and turns-off the regulator-knob (06). More specifically, the driver (23) rotates the holding portion (22a) such that the regulator-knob (06) is turned to OFF-position from the ON-position. In one embodiment, the driver (23) is in wired connection (23a) with the weighing unit (10) to receive the power. Alternatively, the driver (23) can be externally powered by other power source (not shown). Yet in another embodiment,
15 the driver (23) can be in wireless connection with the external power source or the power source of the weighing unit (10).

[14] In one embodiment, the regulator-knob holder (22) is foldable in operation i.e. in case of operative configuration, the regulator-knob holder (22) is clamped/attached
20 to the regulator knob (06) and in inoperative configuration can be released gently by taking it up or down with its joints attachments, such as with screw/fitting rivet fastener (22c). In inoperative configuration, the holding portion (22a) rest into the adjustable handle (22b) by manipulating the joint attachment via screw/fitting rivet fasteners (22c) and flexible in movements as per need and usage. The holder portion
25 (22a) shall be clamped all time to regulator cylinder, but the holder portion (22a) can be disassembled when the gas cylinder (05) is refilled or need. The adjustable handle (22b) would be fixed and clamped and remains unchanged with the gas cylinder (05).

[15] The gas sensor (30) is positioned in vicinity of the gas cylinder (05) and senses
30 the amount of gas in the surrounding of the gas cylinder (05). In one embodiment, the

5 unit (10) and the regulator knob actuation unit (20). The control unit (40) is provided with an active SIM card stored with a first registered number of a gas cylinder vendor a second registered number of the gas cylinder user. Typically, the control unit (40) is in wireless connection with one or more of the gas sensor (30), the weighing unit (10) and the regulator knob actuation unit (20). Alternatively, the control unit (40) is in
10 wired connection with one or more of the gas sensor (30), the weighing unit (10) and the regulator knob actuation unit (20). The control unit (40) can be positioned inside the weighing unit (10) near the gas sensor (30) or can be in vicinity of the main power supply (50).

15
[17] In event when the weighing unit (10) determines weight of gas in the gas cylinder (05) below the predefined limit defined in the weighing unit (10), the weighing unit (10) communicates to the control unit (40) and the control unit (40) notifies the first registered number to place an order for replenishment. In event when
20 the gas sensor (30) senses amount of gas in the surrounding of the gas cylinder (05) more than a predefined value defined in the gas sensor (30) then the gas sensor (30) communicates to the control unit (40) to actuate the driver (40) and activates the regulator-knob holder (22) to turn-off the regulator-knob (06). The control unit (40) further notifies the second registered number and inform about the sensed gas more
25 than the predefined value. Further, the control unit (40) is in connection with a main power supply (50) and operates to trip-off the main power supply (50). In one embodiment, the control unit (40) disposed in vicinity of the main power supply (50).

30 alerting device can provide a sound alert, a light alert and combination of light and sound.

[18] The present disclosure also discloses a method for controlling and managing a gas cylinder. The best method for controlling and managing a gas cylinder is performed by providing the system (100) for controlling and managing a gas cylinder
5 (100) which includes the weighing unit (10), the regulator knob actuation unit (20), the gas sensor (30) and the control unit (40). By use of the system (100), initially continuously monitoring the weight of the gas cylinder by positioning the gas cylinder on the weighing unit (10) positioned on the flat surface (11). The weighing unit (10) is powered by the power source (12). The next step is continuously monitoring, by the
10 gas sensor (30), amount of gas in the surrounding of the gas cylinder (05), wherein the gas sensor (30) positioned in vicinity of the gas cylinder (05). Providing the regulator knob actuation unit (20) which is defined with the clamp (21), the regulator-knob holder (22) and the driver (23). The regulator-knob holder (22) is clamped with the regulator-knob (06) of the gas cylinder (05). The driver (23) is in connection with the
15 regulator-knob holder (22) and turns-off the regulator-knob (06).

[19] The next step is establishing communication of the control unit (40) with the gas sensor (30), the weighing unit (10) and the regulator knob actuation unit (20), wherein the control unit (40) is provided with an active SIM card stored with the first
20 registered number of the gas cylinder (05) vendor and the second registered number of the gas cylinder (05) user. The present disclosure is not limited to registering one gas cylinder (05) vendor and one gas cylinder (05) user, the control unit (40) can have multiple registrations of gas cylinder (05) vendors and gas cylinder (05) users. For example, one gas cylinder (05) vendor and two gas cylinder (05) users can be
25 registered.

[20] In event when the weighing unit (10) determines weight of gas in the gas cylinder (05) below the predefined limit defined in the weighing unit (10). The weighing unit (10) communicates to the control unit (40) and the control unit (40)
30 notifies the first registered number to place the order for replenishment. Further, ,the weighing unit (10) can help us understand the weight of the gas cylinder (05) upon

arrival and hence enables the user to understand whether there is any pilferage or theft of gas before arrival at the user. Thus, when less weight is detected by the weighing unit (10), the gas cylinder (05) either cannot be accepted or can ask for replacement.

5 [021] In event when the gas sensor (40) senses amount of gas in the surrounding of the gas cylinder (05) more than a predefined value defined in the gas sensor (40) then the gas sensor (40) communicates the control unit (40) to actuate the driver (40) and activate the regulator-knob holder (22) to turn-off the regulator-knob (06). The control unit (40) further notifies the second registered number and informs about the sensed
10 gas more than the predefined value. Further, the control unit (40) which is in connection with the main power supply (50) operates to trip-off the main power supply (50).
