3G data acquisition module

The invention discloses a 3G data acquisition module and belongs to the technical field of data acquisition. By means of Internet transmission, GPRS or 3G/4G cards, relevant data monitoring is performed on software of a computer and a mobile phone client. A CAN CJ extension module serves as a core unit of the acquisition module, a communication mainboard 3G module is embedded in the CAN CJ extension module, remote data are read from single-control modules, a communication module is connected with the single-control modules through 485 communication and CAN bus communication, the extension module is connected with four pressures, four PT100 resistors and two exhausting temperatures for monitoring, and the gas inflow temperature, the water temperature, the oil temperature, the gas inflow pressure, the crankcase waste gas tail end pressure, the fuel pressure, the exhausting temperature and other parameter values of a power generator can be respectively measured in real time. The 3G data acquisition module has the advantages that firstly, functional configuration is modular, and product structures are integrated; secondly, the 3G data acquisition module is resistant to vibration, high temperature and low temperature; thirdly, operation is easy and visual; fourthly, the 3G data acquisition module is easy and convenient to install and use; fifthly, the cost performance is high.
