摘要:

为了扩展测试系统挂接传感器的数量,使不同类型传感器在配置时实现即插即用,提出了一种基于TEDS接口的智能传感网络系统；此网络系统采用温度传感器和倾角传感器分别对-55～+125 ℃环境温度和-90°～+90°的倾角进行实时测量；通过TEDS(Transducer Electronic Data Sheets)技术实现了传感器的智能化要求；传感器采集到的信号,经过FPGA进行相关的处理,通过RS485总线传输到总的网络适配器,网络适配器的控制单元通过USB接口上传给上位机；实验结果证明,温度测量精度达到0.1 ℃,倾角的测量精度达到0.5°,验证本系统的稳定性和可靠性。

Abstract:

To extend the number of articulated sensors of the system, This paper designs the intelligent sensor network system. The temperature sensor display the temperature(– 55 ~ + 125 ℃), the angle sensor collects the angle(-90°～+90°).the system achieves the intelligent sensor requirements through the TEDS technology. The Sensor collect the signals which are analyzed by FPGA, the signals are transmitted to NCAP through the RS485 bus, the network transmits the signals to the PC via USB interface. The experimental results show that the actual measurement accuracy of the temperature can reach 0.1 ℃, the actual measurement accuracy of the angle can reach 0.5 °, The system has a very high practical value, the results verify the stability and reliability of this system.
