As shown in fig. 1 and 3, the quick valve closing module of the embodiment is connected with the MCU module, and the quick valve closing module is used for closing the motor valve when external power supply is lost. In addition, when the upper computer finds that the pressure in the pipeline is abnormal, a quick valve closing instruction is sent to the motor valve control device of the gas pipeline, and the MCU module immediately closes the valve through the quick valve closing module.
The power supply part circuit of the embodiment can realize the switching between external power supply and battery power supply, and the power supply principle is as follows: as shown in fig. 7, the external power supply is 5.2V to 7.2V voltage input, and the power supply processing chip U9 performs voltage stabilization to output 5V voltage. The battery power supply voltage is 3.6V, and the voltage is stabilized through the power supply processing chip U8. Finally, the two paths of input power supplies are converted into 3.3V voltage through a power supply conversion module U4 for each module to use. When the external power supply input voltage is greater than the battery voltage, an external power supply input mode is employed. When no external power supply voltage is input, the battery power supply mode is immediately started to provide a backup power supply for the equipment, at the moment, the external power supply detection module detects that external power supply is turned off and sends a power-off signal to the MCU module, the MCU module immediately sends a quick valve closing instruction, and the equipment completes quick valve closing action. After the valve is closed, the gas pipeline manager can be prompted to handle the abnormal phenomenon of external power supply.

The manager can remotely control in the upper computer, remotely control the motor valve switch and the valve opening, and do not need to time and labor again to manually adjust in the pressure regulating station. When the MCU module receives the valve angle instruction, the MCU module converts a corresponding voltage value according to the length of the valve travel switch, and then the voltage value is compared and output through AD conversion, so that the motor valve moves to a set angle.
