Intelligent quantitative guided explosive charge is the first developed equipment in China, which is mainly used for large-scale industrialization of explosives. The project has high security. Through the database processing technology, muffler hose refinement equipment technology unsafe factors, the project adopts intelligent response control. It has high market application value. The automatic control system is added to the original basic unit to realize the automation function. When the power supply suddenly stops, the unit can start automatically, run automatically, switch over automatically, transmit power automatically and stop automatically. 1. The unit control system shall be equipped with car muffler, with the following functions: ① with remote start-up interface, it can set delay start and delay stop time to control the automatic start and stop of engine set; ② control output of idle speed, load and oil supply; ③ there are two kinds of speed sources: voltage rate input and speed sensor. ④ With low oil pressure, high water temperature, high speed, emergency stop start fault protection functions. 2. The automatic transfer switch shall include the following three parts: (1) the main contact which can be connected or disconnected between the load and the power supply; (2) the switching mechanism with the main contact that can be switched; 3) the intelligent automatic control module to monitor the power supply and automatically switch the power supply when necessary.
