In response to the actual production situation and meeting production needs, a certain vehicle has a manual control function in the driver's cab. Now, a remote manual control function in the central control room is added. Manual operations are carried out by operators on the remote control panel in the central control room, in conjunction with video surveillance systems and safety monitoring systems. Among them, the cabin operation and remote control console operation can be freely switched between the two states through a switching switch. And standby for remote monitoring function. The operator can remotely control the overhead crane from the remote control chair in the central control room based on high-definition video and remote instructions to perform unloading, lifting, slotting, and coordinating maintenance operations. This significantly reduces the labor intensity of employees, improves the working environment, enhances safety and efficiency, and allows them to work like office white-collar workers, enhancing their sense of belonging and solving the problem of difficult recruitment.
To ensure smooth network data, 5G+technology is used for linking. The upward speed of the crane network is required to be no less than 200Mbps, and the end-to-end reliability of the network should reach 99.9% or above. Using full 5G communication to cover the overhead crane area and remote operation center. 5G has the characteristics of high speed, large bandwidth, low delay and high reliability. It is precisely for the needs of the industrial Internet in connection diversity, performance difference and communication diversity. It can control the network waiting time at the millisecond level, ensure the precise control of the unmanned crane system, and make it possible to improve the level of safe production in the industrial manufacturing field.
The crane control and upper computer monitoring adopt a customized remote control system, which has strong operability, simple instructions, rich graphics, and dynamic display of the main mechanisms. Including the safety monitoring function of the crane, it also needs to have functions such as fault diagnosis, operation record query, historical data archiving, operation management, etc., which can monitor the driving status in real time without affecting the basic operation of the crane.
The system connects the control PLC of the crane through an industrial Ethernet cable, and collects various real-time data of the lifting equipment during operation into the management system. The collected business data, fault chain information, working status and other information are processed and stored, and the operation status of the crane is reflected through some dynamic and intuitive images. The function of reproducing faults when they occur is provided, achieving secondary backup of data, and supporting various functions such as multimedia printing, database storage, and information export.
