Problems solved by technology

In this way, in the process of switching the signal channel, since the switching of the signal channel takes a certain amount of time, the ground control center may lose contact with the work vehicle during the time of signal channel switching, so that the ground control center may lose contact with the work vehicle during this time. The control signal data sent to the working vehicle within a certain period of time is easy to lose, causing the ground control center to lose control of the working vehicle

Abstract

The invention provides a signal channel switching method, device and equipment and a storage medium, the method is applied to a vehicle-mounted mobile terminal, and the method comprises the following steps: establishing a first signal channel with a first underground base station through a first radio frequency module, and performing data transmission with a ground control center through the first signal channel; in the moving process, detecting wireless signals transmitted by a plurality of underground base stations through a second radio frequency module, and determining a second underground base station according to the signal strength of the detected wireless signals; and establishing a second signal channel with a second underground base station through a second radio frequency module, stopping sending the first data to the aboveground control center through the first signal channel, and continuing to receive the second data through the first signal channel when the second signal channel does not meet the receiving condition of the second data sent by the aboveground control center. In this way, in the signal channel switching process, it can be guaranteed that data sent by the ground control center to the vehicle-mounted mobile terminal cannot be lost.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a method, device, device, and storage medium for switching signal channels. Background technique [0002] In work scenarios involving underground operations such as mines, tunnels, and underground mining, it is often necessary to transmit the operation data collected by the operating vehicles underground to the ground control center on the ground through the underground base station. The ground control center uses optical fiber or Ethernet. Establish a communication connection with the downhole base station to receive the operation data uploaded by the downhole base station to process the operation data. During this process, the ground control center can realize remote control of the operating vehicle through data transmission with the operating vehicle located underground. Since the operating vehicle needs to indirectly realize data transmission with the g...
