Remote monitoring and controlling device for air compressor

The utility model discloses a remote monitoring and controlling device for an air compressor. The remote monitoring and controlling device at least comprises an upper computer used for reading, processing and distinguishing air compressor operation information detected by a PLC controller and transmitting remote control commands for controlling the air compressor to load, unload, start and stop; and the PLC controller, wherein the PLC controller and the upper computer are both accessed to an Ethernet switch for networking and communication. The PLC controller comprises a communication module; the communication module is connected with a Modbus protocol conversion server; the Modbus protocol conversion server is connected with an air compressor controller; the air compressor controller is used for controlling and detecting loading and unloading information of the air compressor and transmitting the information to the PLC controller via the Modbus protocol conversion server; and a dry contact of the PLC controller is directly connected with a contact of a contactor coil for controlling the air compressor to start and stop in an air compressor electric circuit. Operation stability of the air compressor is improved, and reliable and stable gas sources are provided.
