Description of the composition of the intelligent crane control system

The overall intelligent crane control system can be divided into a three-level architecture such as equipment level, factory level, and remote management level.

The equipment-level system is the control system of a single intelligent transfer crane. It is a channel for monitoring the operation of a single intelligent crane single equipment. It is responsible for the full active operation of subordinate equipment, executes various instructions issued by the control center, and monitors related Process data transmission to factory-level channels. The equipment-level channel consists of a stand-alone control system, positioning and anti-sway equipment, automatic control and material information scanning system. The single-machine control system is composed of PLC, human-machine interface, frequency converter and various detection components.

After PLC exchanges data with the outside, according to the program control, it drives the operation of the crane's various mechanisms, and completes the full active operation and equipment monitoring. The man-machine interface provides field-level status information display and parameter setting functions, and displays primary information such as power supply, faults, load, hook position, control mode, detection component status, and operating status of various mechanisms. The automatic control and material information scanning system is a system that completes data exchange with the central control system through the form of bus communication, and completes the monitoring and management of a crane. The crane positioning and anti-sway equipment controls the position, speed and swing angle of the crane, trolley, and hook within the error range according to the control algorithm. The primary function of the active monitoring and material information scanning system is to dispatch missions in the workshop according to the material distribution status and process requirements, specifically to actively identify the material distribution status, send and receive information to the monitoring system and crane control system, and issue active operation instructions according to process requirements.
