摘要
介绍了一种基于Freescale MC9S08SH4微处理器和AD7705模/数转换器的智能传感器系统设计,给出了系统硬件电路和软件流程。该系统在普通传感器上增加了软件调零、浮点数据处理、多点测量及RS-485双向通信等功能。工程应用表明,该系统具有测量精度高、结构紧凑、运行稳定、抗干扰能力强等优点。
An intelligent sensor system comprising Freescale MC9SOSSH4 and AD7705 is introduced. The hardware circuits and software frame are given. Functions such as software zero adjustment, floating data processing, multi-nodes measurement and RS- 485 intercommunication are added to common sensors. Project practice shows that this intelligent sensor system has many advantages such as high accuracy, compact structure, high reliability and strong anti-jamming ability.
