2G/4G/NB autonomous switching LoRa gateway system

Abstract

The invention discloses a 2G / 4G / NB autonomous switching LoRa gateway system. The system comprises a power supply, a 2G / 4G / NB uploading module, a LoRa data module, a main control module, and a WIFI + GPS debugging management and positioning module. The master control module comprises an MCU master control chip of the NXP company, a high-capacity DDR and EMMC storage. The data processing module is used for receiving the data reported by the LoRa data module, processing the data and then uploading the data through the 2G / 4G / NB uploading module, the uploading mode can adopt a 2G / 4G / NB mode to meetdifferent geographical environment requirements, and meanwhile, the NB module can independently adapt to an NB base station to upload the data to an NB cloud platform. According to the invention, LoRa and NB terminal equipment information adopted by a smart city can be integrated; unified comprehensive management can be achieved, management benefits are improved, uploading channels are integrated, the low-power-consumption performance of the terminal can be improved, regional management is clear, management efficiency is greatly improved, invalid coverage and LoRa / NB autonomous switching areavoided, management end integration is achieved, and a reasonable management system is constructed.

Description

technical field [0001] The invention relates to the technical field of smart city construction, in particular to a LoRa gateway system for 2G / 4G / NB autonomous switching. Background technique [0002] In the current smart city construction, using local terminal data collection (such as water meters, parking space detection, range cargo locators, etc.), through LoRa and other transmission methods, the collected data is uploaded to the cloud through an independent local terminal, and the means of uploading to the cloud is 2G , NB, 4G, etc., and then identify and manage them in the cloud, constructing the regional modules of the smart city, improving the quality and convenience of public services, and saving labor costs and related management costs. However, because these data upload management devices are all independently uploaded to the network, the individual cost control is relatively high, and it is not conducive to comprehensive product management and complex and differen...
