由89c52和8254组成数据处理电路。外部测量信号以外部中断方式触发89c52读取8254计数。
The data acquisition circuit is composed of chip 89C52 and 8254. External measuring signal at interrupt mode triggers 89c52 to read number in 8254 counter.
采用这样的方式，可以做到统一管理触发，并且各个延时触发信号之间具有相关性，彼此间的晃动比较小。
Using this signal, we can unify the work time of all the instruments of the accelerator, and the touch off signals are related from each other, the twitter among the signals is small.
