Car-mounted terminal, remote controller, communication system and networking method based on LoRa technology

Abstract

The present invention is applicable to the technical field of automobile communication, and provides a vehicle-mounted terminal, a remote controller, a communication system and a networking method. The communication system includes: a vehicle-mounted terminal based on wireless spread spectrum technology; The remote controller of the technology is used for two-way communication with the vehicle-mounted terminal through wireless spread spectrum signals, and then connected with the electronic control system of the vehicle through the vehicle-mounted communication terminal to wirelessly control the vehicle; The user's mobile terminal is used for two-way communication with the remote control through the Bluetooth network, and then two-way communication with the vehicle terminal through the remote control. The present invention uses wireless spread spectrum technology and low-power bluetooth technology to realize the human-vehicle information interaction between the user's mobile terminal and the car, which is not affected by the signal transmission distance, realizes the remote control function of the car, and has low cost, Low power consumption, good signal transmission effect and so on.

Description

technical field [0001] The invention belongs to the technical field of automobile communication, and in particular relates to a vehicle-mounted terminal, a remote controller, a communication system and a networking method based on LoRa technology. Background technique [0002] In the process of using a car, whether it is manually controlling the car or remotely controlling the car, it is necessary to communicate with the car continuously. The existing wireless communication equipment for human-vehicle interaction is usually a remote control based on infrared technology or using GSM, Smart mobile terminals for mobile networks such as 3G and 4G. [0003] However, the remote controller based on infrared technology in the prior art is extremely susceptible to interference from the surrounding environment, has poor penetration and limited signal transmission distance, while the smart mobile terminal based on the mobile network needs to consume network traffic, which increases the...
