According to the requirement of online measurement, the control system is expanded by adding SRAM for storage sample data, the real time clock for counting, and the power logic addressable latch for peripheral such as valve and DC Motor.

• 根据在线自动测量的实际要求,在最小系统基础上扩展了大容量的静态存储器,实时时钟和功率逻辑可寻址锁存器分别用于暂存大容量的数据,记录数据采集时间以及控制电磁阀、直流电机等外围设备。
