Online detection system and online detection method for electromagnetic valve

The invention discloses an online detection system for an electromagnetic valve. The online detection system comprises a water vapor integrated test module, a cloud server, an electromagnetic valve reliability tester, a pressure sensor, a remote transmission module and an APP software module, wherein the water vapor integrated test module sets required detection pressure and a required medium of aflowing direction tested piece; the electromagnetic valve reliability tester is used for acquiring a pressure value of the tested piece, which is detected by the pressure sensor and transmitting acquired data to the cloud server; and the APP software module is connected with the cloud server through the remote transmission module. A detection method is characterized in that all parameters of theelectromagnetic valve are viewed through APP software. Therefore, the detection process and the result of the electromagnetic valve can be quickly and visually reflected, and information sharing can be realized; relevant depar
