AST electromagnetic valve detection device and system

The utility model discloses an AST solenoid valve detection device and system, and relates to the field of detection, an AST solenoid valve is electrified when working normally, a coil of the AST solenoid valve is electrified at the moment, and the coil of the AST solenoid valve has magnetism when being electrified, so that the AST solenoid valve is not electrified. Therefore, whether the AST electromagnetic valve works normally or not can be detected and prompted by combining the magnetic attraction principle and arranging the magnetic control switch and the prompting device. After the power supply is powered on, if the magnetic control switch is closed at the moment and the prompting device gives out a prompt, it is proved that the coil of the AST electromagnetic valve is electrified at the moment, and the AST electromagnetic valve works normally; and if the magnetically controlled switch is switched off and the prompting device does not give out a prompt at the moment, the coil of the AST electromagnetic v
