Problems solved by technology

[0004] The existing LoRa wireless single light controller and LoRa wireless collector realize the LoRa wireless control and collection technology within a certain long distance, but because the LoRa wireless signal will weaken with the increase of the distance and the LoRa wireless signal will attenuate when encountering a tunnel bend Due to the limitations of the network, in some tunnels and roads with a distance of more than 2 kilometers, it is impossible to achieve global control and collection through a LoRa wireless coordinator

Abstract

The invention relates to the technical field of communication, and discloses a LoRa wireless relay communication system, method and device so as to realize a long-distance communication function of LoRa wireless equipment. The method is based on a LoRa wireless repeater and comprises the following steps: analyzing the classification of host commands from a LoRa wireless coordinator; then corresponding processing is carried out according to different categories of host commands, and if the host commands are the first category of host commands, corresponding self-operation is executed; if the command is the non-return information command in the second type host command, switching back the host command to the local frequency band after relaying to the next subnet from the frequency band of the next subnet; and if the instruction is the instruction for reading the information, relaying the frequency band of the next subnet to the next subnet by the host command, switching to the local frequency band after the corresponding instruction for returning the information is returned, and then relaying the instruction for returning the information to the previous network by the local frequencyband.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a LoRa wireless relay communication system, method and device. Background technique [0002] LoRa is a long-distance wireless transmission technology based on spread spectrum technology, which has the characteristics of long transmission distance, low power consumption, long battery life, multi-node and strong anti-interference ability. It can realize data collection, remote communication and data forwarding of equipment. [0003] With the rapid development of my country's highways and the acceleration of urban construction, tunnel lighting and urban road lighting have increased rapidly, and the field equipment such as lighting fixtures, sensing equipment, and ventilation equipment used has also gradually increased. In order to improve the convenience of tunnel lighting and urban road lighting system construction, achieve smooth control of tunnel brightness to mee...
