系统控制电路是VCD机整机电路和机械动作的指挥中心,VCD机是否进入正常工作,关键取决于系统控制电路工作是否正常。系统控制电路主要由系统控制微处理器、功能操作键、各种状态检测开关、VFD显示电路、机械控制电路、以及各种端口扩展电路等组成。其中,系统控制微处理器(CPU)是整个控制系统的核心。图5是单片CPU系统
System control circuit VCD machine circuit and mechanical movement command center, VCD machine into the normal work, the key depends on the system control circuit is working properly. System control circuit is mainly composed of system control microprocessor, functional operation keys, various status detection switches, VFD display circuit, mechanical control circuit, and various port expansion circuits. Among them, the system control microprocessor (CPU) is the core of the entire control system. Figure 5 is a single-chip CPU system
