Motion control system for automobile crane and safety control method for motion control system

Abstract

The invention discloses a motion control system for an automobile crane and a safety control method for the motion control system. The motion control system comprises the automobile crane and a safetycontrol system for the automobile crane, and the safety control system for the automobile crane is composed of a cantilever crane control system, a lifting appliance control system, a walking controlsystem, a conventional vehicle control system, a safety protection system and the like. According to the motion control system and the safety control method thereof, when safety control is carried out on the automobile crane, CAN bus control is introduced, the CAN bus protocol is a structurally open and broadcast type network communication protocol, and a CAN bus is called a controller local areanetwork field bus; and as the controller local area network bus with a good application potential, in recent years, the CAN bus is more and more widely applied to the fields of automobile computer control systems, textile machinery, packaging machinery, papermaking machinery, agricultural machinery, engineering machinery, robots and other open type distribution intelligent control.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to a vehicle crane motion safety control system and a control method thereof, which are suitable for use in construction crane safety control. Background technique [0002] Truck cranes (referred to as truck cranes) are mainly used in engineering teams, construction industries, and power installation departments such as roads, bridges, construction, and emergency rescue. The truck crane safety control system is a system that provides a highly reliable safety protection method, which can avoid the unsafe state of related equipment to the greatest extent, prevent the occurrence of vicious accidents or reduce losses as much as possible after the accident, and protect the production equipment. and most importantly personal safety. However, the traditional control system currently used in the movement safety of truck cranes has the following deficiencies: (1) The commun...

AI Technical Summary

Problems solved by technology

However, the traditional control system currently used in the movement safety of truck cranes has the following deficiencies: (1) The communication method is not flexible enough to conveniently form a multi-machine backup system; (3) It is connected with other nodes on the bus, which affects other operations on the node; (4) The reliability of the system is low, and the maintenance cost of the product is high; (5) Remote detection and fault diagnosis cannot be realized, and the degree of automation is low

The degree of automation of this solution is low, and remote detection cannot be realized, which affects the reliability of the system
