Problems solved by technology

This method can only simply detect the opening and closing state of the solenoid valve, and cannot fully detect other working states of the solenoid valve
At the same time, this detection method also needs to set up a special external signal line, which increases the number of wiring on the solenoid valve and increases the cost of detecting the working state of the solenoid valve.

Abstract

The invention discloses a detection system for the working state of a solenoid valve, which includes a power supply module, a sampling module and a control module, the control module is respectively connected in series with the power supply module and the sampling module, and the power supply module and the sampling module The two ends of the solenoid valve to be detected are respectively connected correspondingly, and the power module is used to output a fixed pulse width power supply signal to the solenoid valve to be detected; the sampling module is used to collect the output voltage of the solenoid valve to be detected; The power supply module performs pulse control, and determines the working state of the electromagnetic valve to be detected according to the sampling signal obtained by the sampling module. The electromagnetic valve operating state detection system of the present invention can effectively detect various operating states of the electromagnetic valve, has a simple structure, and does not require special improvement or design of the electromagnetic valve.

Description

technical field [0001] The invention relates to the field of industrial equipment state detection, in particular to a system for detecting the working state of an electromagnetic valve. Background technique [0002] One of the traditional detection methods for the working state of the solenoid valve is to use a magnetic action mechanism to attract the reed switch when the solenoid valve is closed, indicating that the solenoid valve is closed. This method can only simply detect the opening and closing state of the solenoid valve, but cannot fully detect other working states of the solenoid valve. At the same time, this detection method also needs to set up a special external signal line, which increases the number of wiring on the solenoid valve and increases the cost of detecting the working state of the solenoid valve. Contents of the invention [0003] Based on the above-mentioned defects in the prior art, an embodiment of the present invention provides a solenoid valve...
