High-precision backing control system of heavy truck

Abstract

The invention provides a high-precision backing control system of a heavy truck. The whole system is connected in parallel with original circuits and stop lamp systems of the heavy trucks; two laser ranging systems are mounted on the left side and the right side of the rear end of the heavy truck; the laser ranging systems convert measured range information into electric current signals and transmit the electric current signals to a real-time control system in a driving cab; a video monitoring system transmits on-scene conditions to the real-time control system in real time; the real-time control system gives out an alarm signal according to the conditions provided by the video monitoring system on one hand, and processes the electric current signals provided by the laser ranging systems and timely controls an auxiliary brake braking system on the other hand, so that braking of a brake and accurate positioning of the truck can be ensured. The high-precision backing control system utilizes high-precision laser ranging devices, performs emergency braking or remote control braking to the auxiliary brake braking system via the real-time control system, realizes high-precision positioning control on the heavy truck, and can completely satisfy conditions and demands for receiving and loading in a space launch site.

Description

technical field [0001] The invention relates to high-precision measurement of heavy trucks, high-reliability emergency braking and monitoring of the Internet of Things, in particular to a high-precision heavy truck reversing control system. Background technique [0002] In the field of industrial production and national defense construction, the movement, handling and installation of large structures are becoming more and more frequent. Large-scale transportation equipment has been developed abroad for many years. With the development of contemporary industrial technology, especially driven by hydraulic transmission and electronic control information technology, the field of large-scale equipment road transportation vehicles has developed rapidly, and the technology has gradually matured. [0003] The basic forms of large-scale road transport vehicles in foreign countries are trailer vehicles and self-propelled vehicles, while domestic research and development of large-scale...
