Electric energy meter concentrator communication module based on LoRa technology

Abstract

The invention discloses an electric energy meter concentrator communication module based on the LoRa technology. The communication module comprises a core processor connected with a double LoRa radiofrequency module, an RS232 communication module, a 485 communication module, a serial port communication module and a state display module respectively. Therefore, problems that the construction costis high and wiring is trouble, later maintenance is difficult and the fault position and the fault reason are not easy to determine, the wiring terminal is not stable in wiring and lots of wearing ofthe wire is caused in wiring in use, and data can not be uploaded effectively in a cell with the poor 4G network and the like for concentrator meter reading in the prior art are solved.

Description

Technical field [0001] The present invention belongs to LoRa communication technology, and in particular relates to a communication module of an electric energy meter concentrator based on LoRa technology. Background technique [0002] The current data collection technology of concentrators mainly adopts the following forms, one of which is that the power line of the concentrator is connected to the electric energy meter, and the meter is read using carrier waves. The concentrator sends the data to the main station server through the GPRS / 4G network. The other is that the 485 bus of the concentrator is connected with the electric energy meter, and the 485 channel is used for meter reading. The concentrator sends the data to the main station server through the GPRS / 4G network. The above two methods are mature and have been used for many years, but there are still major problems: (1) high construction cost and troublesome wiring; (2) difficult maintenance in the later period, and i...
