According to the working principle of the rest time control system, Mitsubishi PLC is chosen as the control system, the control requirements of the analysis system are analyzed, and the scheme, process and target of the system are designed. The hardware structure of the system, the software program of keystone editing and the operation simulation of the program are introduced. The system through the computer control plc to complete the work, digital tube as a monitor to show the specific time, through the editing of the trapezoidal program set the rest time, with relays as the output, and then according to the set time of the bell, lamp, etc. to control, but also designed a manual button to adjust the time. The system has the advantages of simple installation configuration, convenient and flexible operation, strong practicality, and can also control the working time automatically and efficiently.
