摘要
为了满足工农业生产和科研中监测平面或者空间多点温度场的需要,介绍了一种体积小、便携的多点温度场测试系统的设计方法和开发过程。该系统采用USB和单总线技术,使用户可轻松组建传感器网络,实现多点温度场测试,并具有即插即用功能。同时也给出了系统的结构、工作原理、主要电路和程序流程。
The temperature field of plane or space is always monitored in the field of industry,agriculture and science investigation.The design method and development process of a small-volume,portable temperature field monitoring system were introduced.This system took the USB and 1-wire bus technology to ensure the users can build sensor net with plug and play function easily,and realize temperature field test.The system structure,running-principium,main circuitry and program flow chart were also expounded.
