Remote monitoring device based on GPRS module

Abstract

The invention discloses a remote monitoring device based on a GPRS module, wherein the device relates to the field of remote control. The remote monitoring device includes a PLC control system, a frequency converter, a GPRS module and an upper computer. The GPRS module is connected with the PLC control system and upper computer respectively. The PLC control system is connected with the frequency converter for collecting the operating parameters of the frequency converter, compressing and packaging the operation parameters, and transmitting the running parameters to the GPRS module. The GPRS module is used for receiving the operation parameters and sending the operation parameters to the upper computer, which realizes the real-time remote monitoring of many equipments of the large-scale production-oriented enterprises, improves the data reading efficiency, and solves the defects that the real-time remote monitoring of many equipments of the large-scale production-oriented enterprises isdifficult and the data reading efficiency is low in prior art.

Description

technical field

[0001] The invention relates to the field of remote control, in particular to a remote monitoring device based on a GPRS module. Background technique

[0002] Due to the large-scale production enterprises (such as metallurgy, chemical industry, petroleum, coal, manufacturing, etc.) have huge scale, many department personnel, scattered operating points, large equipment power and a large number of frequency conversion equipment, therefore, it is necessary to monitor the operating status of various equipment , temperature, pressure, flow and other indicators should be monitored in real time, and in case of abnormality in the equipment, an alarm can be issued in time. Because the general industrial control system spans a large area and has a large number of monitoring points, it is required to have a high communication system rate and a fast polling response time. At the same time, some operating points are scattered in the wild and the environment is harsh, requ...
