[0002] The gas emergency shut-off solenoid valve is a safety device mainly used in gas transmission and distribution systems to cut off the gas supply when a gas leak or other emergency is detected to prevent accidents.

[0003] Many existing gas emergency shut-off solenoid valves are just an information island and are not connected to the Internet, making it impossible to achieve remote monitoring and control, which is inconvenient.

[0004] Therefore, further improvements are made to the above problems. Summary of the invention

[0005] The main purpose of the present invention is to provide an intelligent monitoring and management system for solenoid valves based on the Internet of Things, which is linked through a background server, an emergency cut-off solenoid valve and a client. The emergency cut-off solenoid valve monitors various data in real time and transmits the data to the background server to realize remote monitoring; and remote control is realized by issuing control instructions through the background server.

[0006] To achieve the above purpose, the present invention provides an intelligent monitoring and management system for solenoid valves based on the Internet of Things, including a background server and a plurality of emergency cut-off solenoid valves, wherein the background server and the emergency cut-off solenoid valves are wirelessly connected, and the emergency cut-off solenoid valves include a control execution module, a data acquisition module, a communication module, a human-computer interaction module and a power supply module, wherein:

[0007] The data acquisition module collects various sensor data and transmits the obtained sensor data to the control execution module;

[0008] The communication module is used to realize the communication between the control execution module and the background server (including NB-IOT and other communication methods), upload the sensor data (temperature, pressure, concentration, power, working status and positioning, etc.) to the background server and receive relevant instructions from the background server;

[0009] The human-computer interaction module displays the display data transmitted by the control execution module through a display screen and wakes up the display screen through magnetic induction, thereby setting relevant parameters;

[0010] The power supply module is used to provide power to the control execution module, data acquisition module, communication module and human-computer interaction module. The power supply module can obtain power from AC power, batteries, generators and DC power supply (24V DC power line).

[0011] As a further preferred technical solution of the above technical solution, the data acquisition module includes a temperature sensor, a pressure sensor, a (fuel gas) gas concentration sensor and a valve position sensor, wherein:

[0012] The temperature sensor monitors the temperature data inside and outside the emergency cut-off solenoid valve, and transmits the temperature data to the control execution module and displays it on the display screen. The control execution module determines whether the current temperature is within the normal range. If so, the generated temperature qualification information is transmitted to the backend server through the communication module. Otherwise, the solenoid valve is closed through the actuator and the generated temperature abnormality information is transmitted to the backend server through the communication module.

[0013] The pressure sensor monitors the gas pressure data inside the emergency cut-off solenoid valve, and transmits the pressure data to the control execution module and displays it on the display screen. The control execution module determines whether the current pressure is within the normal range. If so, the generated pressure qualification information is transmitted to the backend server through the communication module.

The control execution module determines whether the current concentration is within the normal range (determines whether there is a leak). If so, the generated concentration qualification information is transmitted to the backend server through the communication module. Otherwise, the solenoid valve is closed through the actuator and the generated concentration abnormality information is transmitted to the backend server through the communication module.

[0015] The valve position sensor monitors the switch data of the emergency cut-off solenoid valve, and transmits the concentration data to the control execution module and displays it through the display screen (ON is displayed when it is open, and OFF is displayed when it is closed).

[0016] As a further preferred technical solution of the above technical solution, for the human-computer interaction module, the display screen is provided with a first Hall element, a second Hall element, a third Hall element and a fourth Hall element, and an explosion-proof glass cover is installed outside the display screen. When the magnetic pen is located outside the explosion-proof glass cover and the distance from each Hall element reaches the trigger distance (manual operation can be performed without unscrewing the glass cover), wherein:

[0017] When the magnetic pen approaches the first Hall element, the first Hall element is triggered, thereby waking up the display screen;

[0018] When the magnetic pen approaches the second Hall element, the second Hall element is triggered, and the display page is switched through the click area of ​​the display screen;

[0019] When the magnetic pen approaches the third Hall element, the third Hall element is triggered, and the relevant parameters are adjusted upward (for example, the upper limit of the normal temperature range is adjusted upward) through the click area of ​​the display screen;

[0020] When the magnetic pen approaches the fourth Hall element, the fourth Hall element is triggered, and the relevant parameters are adjusted downward (for example, the lower limit value of the normal temperature range is adjusted downward) through the click area of ​​the display screen.

[0021] As a further preferred technical solution of the above technical solution, for sensor data, sensor data is collected once every first time period (5 minutes). If any sensor data is judged to be abnormal, it is immediately reported to the background server through the communication module. If no abnormality is found, it is reported to the background server every second time period (6 hours).

[0022] As a further preferred technical solution of the above technical solution, the background server is connected to the client for communication (so that each emergency shut-off solenoid valve can be remotely monitored through the client). BRIEF DESCRIPTION OF THE DRAWINGS
