Detailed ways:

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the implementation of the utility model will be further described below in conjunction with specific illustrations.

As shown in Figure 1, a kind of remote monitoring wireless transmitter of the present utility model comprises a PLC equipment controller 2 that has MODBUS communication interface and realizes MODBUS communication, and described PLC equipment controller 2 is as master station; A plurality of equipment with MODBUS communication interface, said equipment is connected by asynchronous serial bus, as a slave station, also includes a GSM device 3 for sending and receiving communication with PLC equipment controller 2, and PLC equipment controller 2 Connection, used to send and receive information with the device administrator through the wireless communication network.

The PLC device controller 2 is provided with a graphic monitor 1, and the graphic monitor 1 has a display monitoring screen for setting the device parameters of a plurality of devices to be monitored into the PLC device controller 2.

The PLC device controller 2 continuously collects the operating information of a plurality of monitored devices as a slave station with a MODBUS communication interface to realize MODBUS communication through the MODBUS industrial network in the form of a master station. The PLC device controller 2 can also input the operation information of each device by means of passive contacts. The GSM device 3 receives a short message inquiring about the operating status of the equipment sent by the remote equipment manager, and transmits this information to the PLC equipment controller 2, and the PLC equipment controller 2 then sends the information on the operating status of each equipment collected by itself Send back the GSM device 3, and then send back the information short message of each equipment running state to the equipment management personnel by the GSM device 3. Or, when abnormalities or failures occur in the monitored equipment, the PLC equipment controller 2 can obtain equipment failure information and equipment parameters in time, and the equipment failure information will be sent to the GSM device 3 by the PLC equipment controller 2, and then the GSM The device 3 sends a message to the equipment management personnel through the wireless communication network. As a result, equipment managers can remotely monitor the operating status of each monitored equipment in real time.
