LoRa data collector and communication method and upgrading method thereof

Abstract

The invention discloses a LoRa data collector, a communication method and an upgrading method thereof. The LoRa data collector comprises a micro-control unit, a LoRa communication module, an RS485 serial port module, an RS232 serial port module, a watchdog module and a power supply unit; the LoRa communication module, the RS485 serial port module, the RS232 serial port module, the watchdog moduleand the power supply unit are connected with the micro-control unit. The collector integrates functions of a relay and a terminal collector, and instruction configuration is issued through a background, so that convenience and quickness are achieved; networking is simple, and deployment is convenient; the data transmission distance is long, the penetrability is strong, and the relay can be used for blind compensation in places which cannot be covered by the gateway; the LoRa data collector has various functions, and through virus type remote upgrading, the upgrading efficiency is improved, andthe maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the communication field of the Internet of Things, and in particular relates to a LoRa data collector, a communication method and an upgrading method thereof. Background technique [0002] LoRa communication is a low-power, long-distance IoT technology proposed by Semtech, which is widely used in wireless meter reading and other fields. LoRaWAN is a low-power, long-distance wireless Internet wide area network built with LoRa technology. LoRaWAN benefits from the gain of spread spectrum modulation and forward error correction code, and LoRa achieves about 2 times the communication distance of cellular technology. [0003] At this stage, LoRa technology is widely used in the sensing layer of the Internet of Things. The sensor data is transmitted through the LoRa communication chip, which has the advantages of long transmission distance, strong penetration, and easy coverage. LoRa-based data collectors that have appeared on the ...

AI Technical Summary

Problems solved by technology

[0004] (1) Single transmission mode: LoRa collectors on the market are either based on LoRaWAN or LoRa point-to-point, and cannot be used for multiple purposes, and cannot be flexibly adapted to occasions with a large number of sensors such as smart communities and smart businesses

[0005] (2) The interface mode is single: the external interface of the LoRa collector on the market cannot meet the simultaneous access of multiple sensors, only a small amount of docking, and the communication methods of the sensors are different, so they cannot be deployed uniformly

[0006] (3) The upgrade method is complicated: most of the LoRa collectors on the market do not have remote upgrades, and the efficiency of remote upgrades is low, and they cannot be upgraded in large quantities with high efficiency.
