Embodiment 1

[0057] Please refer to figure 1 , a method for realizing the remote control of an unmanned vehicle, comprising the steps of:

[0058] S1. Monitor two parallel wireless channels for remote control signaling transmission and reception. The frequencies of the two wireless channels are different;

[0059] Specifically, improve the existing wireless communication mode, adopt 433MHz and 2.4GHz dual-frequency redundant backup communication, and use SI4438 wireless module in the 433MHz frequency band, which is small in size, low in power consumption, long in communication distance, and the stable communication distance can reach 2km; 2.4G The frequency band adopts NRF24L01 wireless module, which is stable and reliable, and has a long transmission distance, which maximizes the reliability and stability of the communication link and avoids signal loss and signal errors caused by interference in certain frequency bands; the remote control master uses stm32f103, the clock frequency High,...

Embodiment 2

[0084] Please refer to figure 2 , a terminal 1 for remote control of unmanned vehicles, including a memory 2, a processor 3 and a computer program stored in the memory 2 and operable on the processor 3, when the processor 3 executes the computer program Implement the steps in Embodiment 1.

[0085] In summary, a method and a terminal for realizing remote control unmanned vehicles provided by the present invention monitor two parallel wireless channels for realizing remote control signaling sending and receiving, and the frequencies of the two wireless channels are different; according to the monitored two wireless channels The remote control command sent on the channel executes the operation corresponding to the remote control command. Through dual-frequency redundant backup communication, the reliability and stability of the communication link are maximized to avoid signal loss and error due to interference with the frequency band. , which can ensure the safety and reliabil...

Abstract

The invention provides a method and terminal for remote control of an unmanned vehicle; two parallel wireless channels for receiving and sending remote control instructions are monitored, and the frequencies of the two wireless channels are different. According to monitored remote control instructions sent by the two wireless channels, operations corresponding to the remote control instructions are executed; the reliability and stability of a communication link is maximized to guarantee by double-frequency redundant backup communication, signal disconnection and errors caused by interference due to frequency bands are prevented, and the safety and reliability of remote control of the unmanned vehicle can be ensured.

Description

technical field [0001] The invention relates to the field of unmanned driving, in particular to a method and terminal for realizing remote control of unmanned vehicles. Background technique [0002] Unmanned driving is a technical hotspot at present, and remote-controlled unmanned vehicles are the final transition to unmanned driving. The safety and reliability of unmanned driving are completely limited by remote control. Among them, wireless remote control has many advantages such as simple implementation, convenience, and low price. Therefore, wireless remote control is widely used in various control devices. Wireless remote control can be divided into sound remote control, light remote control, and radio remote control according to the signal transmission mode. From the perspective of information exchange, it can be divided into one-way control and command interactive control. One-way control has simple equipment, easy implementation, and adaptability. Various communicat...
