Abstract

The embodiment of the invention provides a remote control bulldozer safety control method, device and system. The method comprises the steps that control signals are received at least twice in sequence; the receiving delay time of the control signals is calculated according to the at least two times of control signals; and according to the receiving delay time, a vehicle speed limiting instructionof the corresponding level is selected and output, and the level of the vehicle speed limiting instruction is positively correlated with the length of the receiving delay time. According to the remote control bulldozing and safety control method provided by the embodiment of the invention, the safety selectivity and reliability of a remote control bulldozer system can be improved, the intelligentlevel of the bulldozer can be improved, the risk that the bulldozer is out of control is reduced, and the possibility of safety accidents is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of remote control, in particular to a safety control method, device and system for a remote-controlled bulldozer. Background technique [0002] With the development of remote control technology becoming more and more mature, it is more and more used in industrial production, especially for dangerous constructions such as mining and rock breaking, remote control technology is more and more popular. Remote control bulldozers operate in harsh environments through communication media such as radio or 5G signals. However, because the working environment is often susceptible to abnormalities or interference from the network communication system, it often leads to loss of control of the bulldozer while driving or working, or causes safety accidents. [0003] When the traditional remote control or unmanned equipment has abnormal network communication or interference, it will be prompted by ...
