Low-delay remote engineering machinery operation control system and method

Abstract

The invention relates to a low-delay remote engineering machinery operation control system. The low-delay remote engineering machinery operation control system comprises a control device, a remote controller I, a data transfer radio I, a data transfer radio II, a remote controller II and a vehicle-mounted controller; the control device, the remote controller I, the data transfer radio I, the datatransfer radio II, the remote controller II and the vehicle-mounted controller are installed in a remote control cab; the control device is used for sending a control signal; the remote controller I is used for performing coding and protocol conversion after receiving the control signal; the data transfer radio I and the data transfer radio II are used for transmitting control data and state datacoded by the remote controller I; the vehicle-mounted controller is used for controlling an execution mechanism to execute an action; and the remote controller II is used for receiving the signal of the data transfer radio II, decoding the signal, converting the signal into a field bus signal, and sending the field bus signal to the vehicle-mounted controller. The control device comprises a handle, a switch, an accelerator, a brake and a steering wheel. By means of the low-delay remote engineering machinery operation control system and method disclosed by the invention, in dangerous and harshworking environments of dealing with dangerous goods, chemicals, radiation substances, geological disaster relief and the like, hazards on health and security of drivers can be reduced through the remote control of engineering machinery.

Description

technical field [0001] The invention relates to the technical field of Internet communication, in particular to a low-latency construction machinery operation remote control system and method. Background technique [0002] With the rapid development of social economy, people pay more and more attention to the working environment. Poor working environments often bring great difficulty and inconvenience to workers, and some working environments may also cause poisonous, explosive or collapse hazards. No work can be carried out at the expense of the health and safety of workers. With the rapid development of nuclear industry, marine operations, space development and other fields, the robotization of construction machinery is the future direction, and wireless remote control technology plays an important role in it. [0003] In the prior art, the remote control technology of over-the-horizon construction machinery based on 4G network. The principle is to use 4G network communi...

Problems solved by technology

[0004] The 4G network is used to realize the communication between the controlled car body and the remote control device. Therefore, it is dependent on the telecommunications infrastructure and cannot be used directly in areas without 4G signal coverage. It needs to carry a communication base station; 4G network communication has poor reliability and high delay; 4G communication generates fees, and the long-term use cost is relatively high
