基于UART通信的多通道气压采集系统设计

Design of multi-channel air pressure data acquisition system based on UART communication

针对大多数采集系统适用性差等问题,介绍了一种小型化可变多通道气压采集系统。该系统可广泛应用于测高系统、自动气象站及气动系统等,通过UART通信由PC控制单片机选择采集通道并显示结果,利用虚拟串口和Proteus进行仿真并加以实现。结果表明该系统可满足多路气压采集,并可通过PC控制采集通道、准确采集数据及显示。

Against to the bad applicability of majority acquisition system,a miniaturizated alterable multi-channel air pres-sure data acquisition system is introduced. This system can be widely applied to hypsometer system, automatic weather station and pneumatic system etc. It can choose working acquisition channels by SCM and the SCM is controlled and the result is shown by PC thought UART communication. Virtual serial and Proteus are used to simulate the system. The resuits show that the system could satisfy multi-channel air pressure data acquisition requirement.
