The hardware design of microcomputer control system for counter-pressure casting in vacuum

The hardware structure and working principle of vacuum counter-pressure casting microcomputer control system was introduced,and the circuit of pressure detection,the regulating valve control and serial communication I/O were designed.Meanwhile,the debugging of the system was introduced,and finally,the experimental conclusion was drawn.The experimental results indicated that the design of hardware system was reasonable because the system runs well and has achieved the design target.
