摘要
设计开发一套多路传感信号演示实验系统。该系统主要由多种传感器及信号采集装置、多路信号转换装置、PC机实时显示界面3部分组成。传感器及信号采集装置包括：由霍尔传感器采集信号的弹簧振子演示装置、压力传感器演示装置,超声波安防测距演示装置等。多路信号转换装置采用单片机控制各通道的选通,系统实现了多通道信号的方便切换,便于在大屏幕投影设备实时显示多种演示效果,充分利用了单机通信有限的接口资源。PC机界面采用VB6.0软件编写,系统操作方便,界面美观。
The paper presents a multi-sensor signal demonstrative experiment system,which is composed of the multi-sensor signal collection device,the multi-channel signal converter device and the PC real-time display interface.The multi-sensor signal collection device includes the spring oscillator demonstrative device using Hall sensor,the pressure sensor demonstrative device,as well as the security and defense and distance measurement demonstrative device using ultrasonic wave,etc.The multi-channel signal converter device adopts single-chip computer to control the channel gating.Making best use of the limited interface resources and easily switching among the multi-channel signal devices,the system facilitates the display of various demonstrative experiments for large-screen projection.The PC interface,compiled by the VB software,is convenient and user-friendly.
