Abstract: In view of problem of low efficiency existed in traditional storage which separates crane control and storage management, the paper proposed a scheme of unmanned storage which takes crane as execution unit based on an example of waste storage management. The scheme uses PLC to collect height, transport time and stirring time of waste at different locations and uses IPC to process data and determine where waste should be transported, stirred and charged, and then IPC sends action triggering instruction to PLC which controls motion of crane. The result of technical test showed that the scheme can realize unmanned storage and improve production efficiency greatly.
