Control system and control method for straight arm type lorry-mounted crane

Abstract

The invention discloses a control system and control method for a straight arm type lorry-mounted crane, and belongs to the technical field of straight arm type lorry-mounted crane control. The invention aims to provide the improvement of a hardware structure of the control system for the straight arm type lorry-mounted crane. According to the technical scheme, the control system involves a hydraulic control system and a crane torque protection device and further involves a main controller, wherein the hydraulic control system involves an operation controller, a hydraulic valve controller and a hydraulic valve set, and the crane torque protection device comprises a torque control main machine; data collected by an arm telescopic length sensor, an arm variable amplitude angle sensor and a lifting weight sensor are transmitted to the torque control main machine through an A / D interface, and data collected by a rotation angle speed sensor are transmitted to the torque control main machine through a high-speed counter interface; and the main controller is connected with the torque control main machine, the operation controller and the hydraulic valve controller through a CAN bus correspondingly. The control system and control method for the straight arm type lorry-mounted crane are applied to the straight arm type lorry-mounted crane.

Description

technical field [0001] The invention discloses a control system and a control method for a straight-arm type truck-mounted crane, belonging to the technical field of straight-arm type truck-mounted crane control systems. Background technique [0002] Straight-arm truck-mounted cranes are widely used in national defense, mining, freight, construction and other fields. The general-purpose straight-arm truck-mounted crane control system consists of a crane moment protection device and a hydraulic control system. The crane moment protection device is used as a separate crane operation safety monitor. The alarm protection device, except for sharing alarm information with the hydraulic control system, is basically two relatively independent systems. During operation, in addition to observing the movement of the crane, the operator pays attention to the alarm information of the crane moment protection device. Only when the alarm information is sent out, the operator can take corres...

AI Technical Summary

Problems solved by technology

During operation, in addition to observing the movement of the crane, the operator pays attention to the alarm information of the crane moment protection device. Only when the alarm information is sent out, the operator can take corresponding measures according to the content of the alarm information. When some operation failures or accidents occur, Operators are too late to take any remedial measures, resulting in equipment failure or operating accidents
