[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] The embodiment of the present application provides a monitoring system based on gas valve control.

[0031] Please refer to Figure 1 , a monitoring system 10 based on gas valve control, comprising: an integrated sensor 100, a gas valve control terminal 200, a gas switch valve 300, a control terminal placement rack 400, a mobile terminal 500 and a central control platform 600;

[0032] It should be noted that the integrated sensor includes: a gas detection sensor, a temperature sensor, a smoke sensor, a positioning module and a first data transceiver module, and the gas detection sensor, the temperature sensor and the smoke sensor are electrically connected to the first data transceiver module respectively.

[0033] Specifically, the gas detection sensor can detect the concentration of methane and carbon monoxide in the air, the temperature sensor can detect the temperature of the air, the smoke sensor is used to sense smoke particles in the air, and will issue an alarm when it senses that the smoke in the air exceeds the standard. The positioning module is used to locate the geographical location of the system, so that when a gas leak occurs (that is, the gas concentration or carbon monoxide concentration in the air exceeds the standard), it can facilitate maintenance and rescue personnel to carry out maintenance and rescue work as soon as possible. The data transmission module is used to receive and send the temperature, methane concentration and carbon monoxide concentration sensed by the gas detection sensor and the temperature sensor.

[0034] It should also be noted that the gas valve control terminal includes: a control module, a drive motor, a gas valve grasping mechanism, a second data transceiver module and a data comparison module. The second data transceiver module is connected to the first data transceiver module by wire or wirelessly, the second data transceiver module is electrically connected to the data comparison module, and the data comparison module is electrically connected to the control module. The data comparison module is used to compare the sensor data received by the second data transceiver module with the pre-set environmental data, and send a command to open or close the gas switch valve to the control module. The control module is used to control the drive motor to drive the gas valve grasping mechanism to open or close the gas switch valve.

[0035] Specifically, after receiving the data of temperature, methane concentration and carbon monoxide concentration transmitted by the first data transceiver module, the second data transceiver module transmits the data to the data comparison module, and the data comparison module compares the data with the preset data of temperature, methane concentration and carbon monoxide concentration, so as to determine whether there is a gas leak or a fire. When the data value received by the second data transceiver module exceeds the preset data of temperature, methane concentration and carbon monoxide concentration, the data comparison module determines that there is a gas leak or a fire, and sends a command to close the gas switch valve to the control module at the same time. After receiving the command, the control module controls the operation of the drive motor, thereby driving the gas valve grasping mechanism to close the gas switch valve. In this way, the gas switch valve is intelligently closed without supervision. In addition, when a fire occurs near a resident and the smoke of the fire triggers the integrated sensor of the resident, the integrated sensor sends an alarm and sends a sensing signal to the gas valve control terminal at the same time. The gas valve control terminal closes the gas switch valve, thereby achieving the purpose of controlling gas leakage, preventing fire or reducing the spread of fire.

[0036] It needs to be explained again that the control terminal placement rack is used to fix the gas valve control terminal on the gas switch valve so that the gas valve control terminal can control the opening or closing of the gas switch valve; specifically, in order to enable the drive motor to smoothly drive the gas valve grasping mechanism to open or close the gas switch valve, the control terminal placement rack is used to fix the gas valve control terminal. In actual application scenarios, the control terminal placement rack is usually fixed on a wall near the gas switch valve.

[0037] It should be further explained that the mobile terminal is used to establish a communication connection with the gas valve control terminal, and to register the gas valve control terminal online through the mobile terminal, so as to activate the gas valve control terminal on the central control platform, so that the central control platform can comprehensively monitor multiple gas valve control terminals.

[0038] Specifically, the user can remotely control the gas valve control terminal through the mobile terminal to remotely open or close the gas switch valve, and refer to Figure 2, the central control platform is bound to multiple gas valve control terminals to enable community property, gas companies, and fire departments to conduct centralized monitoring of users on the gas network in a large area. After monitoring a gas leak or receiving a gas leak alarm, relevant maintenance and rescue personnel can remotely open or close the gas switch valve through the central control platform to control the dangerous situation. In addition, through the central control platform, relevant maintenance and rescue personnel can accurately locate the home address where the gas leak occurs, so that they can carry out maintenance and rescue as soon as possible. In addition, relevant maintenance and rescue personnel can also use the central control platform to close the gas switch valves in the homes of nearby residents where gas leaks or fires occur, thereby preventing the further spread of the dangerous situation.

[0039] Furthermore, the positioning module is a global positioning system or a Beidou positioning module, and the Beidou positioning module is preferably used.

[0040] Specifically, in order to accurately locate the user's home address and reduce positioning errors, the Beidou positioning module can quickly locate and provide all-weather, real-time positioning services for users in the service area.

[0041] Furthermore, it also includes an audible and visual alarm, which is electrically connected to the gas valve control terminal.

[0042] Specifically, when the data comparison module controls the control module to close the gas switch valve, the gas valve control terminal controls the sound and light alarm to emit sound and light alarms to remind the residents at home.

[0043] Furthermore, the gas detection sensor includes: a gas detection sensor and a carbon monoxide detection sensor; the gas detection sensor is used to detect the concentration of gas in the air, and the semiconductor gas sensor is used to detect the concentration of carbon monoxide in the air; the gas detection sensor and the carbon monoxide detection sensor are semiconductor gas sensors.

[0044] Specifically, the gas here includes liquefied petroleum gas and natural gas. The main components of the gas are alkane gases such as methane, propane, propylene, butane, butene, etc. The gas detection sensor is mainly used to detect the concentration of alkane gas in the air to determine whether there is a gas leak. The carbon monoxide detection sensor is used to check the carbon monoxide concentration in the room to remind people in the room to prevent carbon monoxide poisoning. In a specific application scenario, the integrated sensor is connected to an alarm, and the integrated sensor can be used in environments such as mines, cars, and homes.

[0045] The semiconductor gas sensor is a thermal linear semiconductor sensor, in which SnO is coated on the Pt wire coil. 2In addition to heating, the Pt wire also has the function of detecting temperature changes. When voltage is applied, the semiconductor becomes hot, and the surface absorbs oxygen, which reduces the concentration of free electrons. When combustible gas exists, the concentration of free electrons increases due to the consumption of oxygen in combustion. The thermal conductivity increases with the increase of free electron concentration, and the heat dissipation rate increases accordingly, which reduces the temperature of the Pt wire and reduces the resistance. The change of the resistance of the Pt wire is linearly related to the gas concentration, and it can sensitively detect the concentration of gas and carbon monoxide in the air.

[0046] For further information, see Figure 3 The control terminal placement rack 400 includes a base 410 and a fixing plate 420 . The base 410 is provided with a threaded mounting hole 411 . One end of the fixing plate 420 is fixedly connected to the base 410 .

[0047] Specifically, when installing the base, the base is fixed by using a flat-head self-tapping screw to pass through the threaded mounting hole and drill into the wall, and the fixing plate is used to fix the gas valve control terminal.

[0048] Furthermore, the gas valve control terminal further comprises a shell, the shell is provided with a fixing plate embedding groove, and one end of the fixing plate away from the base is embedded in the fixing plate embedding groove.

[0049] Specifically, by embedding the fixing plate into the fixing plate embedding groove of the shell, the gas valve control terminal can be fixed to the control terminal placement rack, so that the gas valve control terminal can exert force smoothly to open or close the gas switch valve.

[0050] Further, the integrated sensor includes an upper cover and a lower cover, the upper cover is buckled with the lower cover, a reset spring is arranged between the upper cover and the lower cover, one end of the reset spring is fixed to the lower cover, and the other end of the reset spring is used to support the upper cover, a locking piece is arranged in the cover body of the upper cover, a locking groove is arranged in the cover body of the lower cover, the locking piece is snapped with the locking groove, a first metal contact point is arranged on the locking piece, and a second metal contact point is arranged on the locking groove, when the upper cover is pressed, the first metal contact point contacts with the second metal contact point to form a passage.

[0051] Specifically, when the upper cover is pressed, the latching piece in the upper cover is engaged with the latching groove of the lower cover, and the first metal contact point contacts the second metal contact point to form a passage. When the upper cover is pressed again, the reset spring lifts the upper cover, and the first metal contact point is separated from the second metal contact point. At this time, the passage is disconnected. In this way, the integrated sensor has the function of a switch. Further, by pressing the integrated sensor, the integrated sensor transmits the open or close signal to the gas valve control terminal through the first data transceiver module, and further controls the opening or closing of the gas switch valve. It is worth noting that in an emergency such as a fire or an earthquake, the user may not have time to manually close the gas switch valve. The user can press the integrated sensor to control the gas valve control terminal to close the gas switch valve, saving the user's escape time. In addition, when the user presses the integrated sensor to close the gas switch valve, the gas valve control terminal feeds back the situation of closing the gas switch valve to the central control platform, and the central control platform can immediately know that the gas switch valve is closed.

[0052] Furthermore, after the upper cover and the lower cover are buckled, a receiving cavity is formed between the upper cover and the lower cover, and the gas detection sensor, the temperature sensor, the smoke sensor, the positioning module and the first data transceiver module are all arranged in the receiving cavity. That is, a variety of sensors are arranged in the receiving cavity, which saves installation space and plays a certain aesthetic role.

[0053] Furthermore, the central control platform is provided with a data display module, and the data display module is used to display the sensor data perceived by the integrated sensor.

[0054] Specifically, in order to facilitate the property management, gas company and fire department to monitor the plurality of gas valve control terminals more easily, the data display module can display the sensor data sensed by the integrated sensor on a large screen.

[0055] Furthermore, the central control platform can communicate with the mobile terminal via text, voice or video.

[0056] Specifically, when a gas leak occurs, relevant emergency repair personnel can contact the user through the central control platform, and the user can perform emergency repairs under the guidance of the relevant emergency repair personnel to reduce losses.

[0057] For further information, see Figure 4, the gas valve grasping mechanism 220 is a rotating arm, one end of the rotating arm 220 is connected to the driving motor 210, and the shape of the other end of the rotating arm 220 is adapted to the shape of the handle of the gas switching valve 300. Specifically, after receiving the instruction from the control module, the driving arm rotates forward or reversely, thereby driving the rotating arm to rotate forward or reversely to open or close the gas switching valve. It is worth noting that the shape of the gas switching valve can be a disc or a lever, and the corresponding end of the rotating arm is used to clamp the gas switching valve, and will also change with the shape of the gas switching valve, which is not limited here.

[0058] For ease of understanding, the above-mentioned monitoring system based on gas valve control is specifically described below through application embodiments, including:

[0059] In one embodiment, the gas valve control terminal is connected to the mobile terminal via Bluetooth, wireless or wired network, or communication, and any one of a mobile phone APP, a cloud platform or an intelligent background is installed on the mobile terminal. Here, a mobile phone APP is taken as an example. The user registers online on the mobile phone APP and leaves the user's personal information, such as mobile phone number, home address, etc. By adding the gas valve control terminal on the mobile phone APP, the open or closed state of the gas switch valve can be viewed on the mobile phone APP, and an on or off button of the gas valve control terminal can be set on the mobile phone APP, and the opening or closing of the gas switch valve can be controlled by clicking the "on" or "off" button; in addition, after turning on the integrated sensor, the current indoor temperature, gas concentration and carbon monoxide concentration can be viewed on the mobile phone APP. When the indoor gas concentration and carbon monoxide concentration detected by the integrated sensor exceed the safe range, an alarm prompt will appear on the mobile phone APP, accompanied by an alarm sound.

[0060] Furthermore, by binding multiple users' mobile phone APP backends on the central control platform, real-time monitoring of multiple gas valve control terminals can be achieved. The gas conditions in multiple users' rooms can be viewed on the central control platform. Since the mobile phone APP contains the user's mobile phone number and home address, when a gas leak is detected in the user's room, the user can be contacted immediately and rushed to the user's home for emergency repairs. In addition, the central control platform can remotely open or close the gas switch valve in the user's room by entering the backend of the user's mobile phone APP.

[0061] In another embodiment, when a gas leak occurs, the integrated sensor sends the carbon monoxide concentration and the gas concentration in the air to the second data transceiver module of the gas valve control terminal through the first data transceiver module, and the second data transceiver module transmits the carbon monoxide concentration to the data comparison module. The data comparison module compares the received carbon monoxide concentration or gas concentration and finds that it exceeds the preset carbon monoxide concentration and gas concentration. The data comparison module sends a command to close the gas switch valve to the control module, and the control module controls the drive motor to drive the gas valve grasping mechanism to close the gas switch valve.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
