Realize above-mentioned purpose, the technical scheme that the utility model adopts is following: a kind of industrial monitoring system based on the GPRS wireless network is characterized in that: it comprises commercial unit output port, single-chip microcomputer, GPRS module and monitoring cell-phone; The commercial unit output port links to each other with single-chip microcomputer through the RS232/485/422 port; Single-chip microcomputer is the control core; The commercial unit data are detected; Data are passed to server through GPRS module and Internet pass to monitoring cell-phone again, utilize existing GPRS network to carry out data transmission, industry spot is monitored and controlled.

Further, said commercial unit output port comprises equipment running and pressure, temperature and/or data on flows.

Said single-chip microcomputer is main process chip, comprises power circuit, datel circuit and GPRS module interface circuit.

Compare prior art, the utlity model has following beneficial effect:

The utility model is main process chip with single-chip microcomputer; Pass to the GPRS module with gathering the field equipment data of coming through serial ports; The GPRS module again with these data messages transparent be transferred to server, server receives deal with data, supplies the cell-phone customer terminal visit and extracts.Adopt the http communication mode to transmit data between mobile phone and the server.Be connected to Internet through MCU driving GPRS module through the GPRS wireless network and realize online; Mobile phone end is through the http protocol access server; Obtain real time data, the final realization is sent to handset displays with field data, and can carry out processing command to data and turn back to server; Give field apparatus with the user from the pass down the line that mobile phone sends, thereby realize monitoring and management the scene.Make the user can be easily direct Real-time Monitor Management field apparatus from the mobile phone, need not the people and be post, have broad application prospects.

Overcome computer monitor the monitoring of site limitation and SMS untimely, inaccurate, easy to use, investment is little, efficient is high, real-time, aspect Industry Control, still belong to leading domestic level.

The maximum characteristics of this system just are to use the mobile phone computing machine of carrying, and utilize the GPRS wireless network to transmit the multidate information of industry spot clearly, and monitor staff's order is assigned to field apparatus.Realize real-time mobile monitor, strengthen commercial unit monitoring in real time and management.
