基于CANOpen网络的CO2浓度采集节点的设计与实现

摘要

研究了基于CANOpen网络的CO2采集系统.该系统可分为CO2数据采集模块、信号调理模块、A/D采集模块、CANOpen通信模块、串口测试模块和电源模块,主控制器为MC9S08DZ128.本系统可作为CANOpen从节点挂载到CANOpen网络上.测试结果表明,本传感器能够对C02浓度信息进行实时准确的检测和可靠网络传输.%This paper introduces the carbon dioxide (CO2) acquisition system based on MC9S08DZ1 28 and CANOpen.The system can be divided into CO2 data acquisition module,signal conditioning module,A/D acquisition module,CANOpen module,test module and power module.Module can be used as a slave CANOpen node and has a very high effectiveness and accuracy.
