Abstract At present, in the domestic power consumption and distribution system, the long-distance communication between the main station and the power consumption information acquisition terminal is mostly used by GSM, GPRS and other lagging communication solutions , These wireless communication modes have long communication delay and poor communication reliability, which cannot meet the requirements of smart grid and smart Internet of things proposed by the state.. With the rapid development of Internet of things wireless communication technology, LoRa emerges at the right moment. It features free choice of frequency band, long communication distance, strong signal transmission, stable data reception and transmission, and flexible networking Therefore, more and more people are welcome in electricity information acquisition system. The LoRa chip of industrial grade F8l10D-E-MS-N is adopted and combined with the remote acquisition module designed by ATMEL D20,. Is used to realize the function of remote communication. The communication between the communication module and the main station adopts the object-oriented DL/T 698 communication protocol specification. This module innovatively USES the new type of LoRa wireless communication mode, and connects with the main control chip through USB3.0, adding the NFC module. The experiment shows that the wireless communication module has a wide range of communication coverage, rapid networking and high data transmission efficiency.
