负责采集外部信号，如同人们的眼睛，当有移动的物体进入它的工作范围时，它就给主控制器一个脉冲信号。
Responsible for the acquisition of external signals, as people's eyes, when a moving object into its work range, it will give the main controller a pulse signal.
主控制器使用单片机对各个传感器的信号进行采集、分析、计算，并进行补偿，得到所需数据，再将各种数据送到液晶显示器显示。
The master controller uses a single-chip computer to collect, analyze, compute and compensate the signals of all sensors, and gets the needed data, then displays all data via the LCD.
该数据采集系统采用TI公司的TMS320 LF 2407 A芯片为主控制器，另外设计了相应的外围信号调理电路、存储模块、通信模块等。
The data acquisition system adopted TMS320LF2407A chip of ti as main controller, in addition, designed peripheral signal processing circuit, memory module, communication module and so on.
