Problems solved by technology

[0004] However, the development of mobile communication technology makes the base station coverage of various mobile communication networks unbalanced. Therefore, the signal strength of mobile communication networks in different regions is also different, and the signal strength of each channel carrying network communication signals is different. The difference in signal transmission capabilities, therefore, ensuring the stability and efficiency of signal transmission has become an urgent technical problem in the field of using mobile communication networks to realize the control of remote control driving equipment

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] In one embodiment, such as figure 1 As shown, a method for channel switching among three channels includes the following steps:

[0033] S1. Obtain the signal strength values ​​of the three channels, and select the channel with the largest signal strength value as the current communication channel for communication;

[0034] S2. Monitor the signal strength value of the current communication channel, if the signal strength value is lower than the strength threshold of the current communication channel, proceed to S3, if the signal strength value is higher than the strength threshold of the current communication channel , continue to monitor;

[0035] S3. Obtain signal strength values ​​and strength thresholds of the other two channels except the current co...

Abstract

The invention relates to a channel switching method and system in multiple channels. With the provided method, the signal strength of a current communication channel carrying out data communication can be guaranteed, so that current communication channel signal strength reduction due to network congestion or area changing can be avoided. Therefore, a communication fault occurring between a remote control device and a driving device in the remotely controlled driving device can be avoided; and thus stability and high efficiency during the operation process of the remotely controlled driving device can be improved.

Description

technical field [0001] The invention relates to the field of communication control, in particular to a method and system for switching channels among multiple channels. Background technique [0002] The remote control driving equipment and its control device usually communicate directly through civil radio and wifi to transmit control signals and data signals. Due to the short transmission distance of radio and wifi and being easily affected by the terrain, the control device cannot remotely control the aircraft. To solve the above problems, someone proposes to use a mobile communication network to realize the control of the remote driving equipment. [0003] From the digital cellular communication system 2G developed in the late 1980s to the widely used 3G mobile multimedia communication system, 4G high-speed mobile communication system, and even VoLTE technology based on 4G networks, the mobile communication network technology is also developing continuously. It becomes p...
