基于CAN总线的温室环境温度监测系统

Temperature Monitoring System of Greenhouse Based on CAN Bus

对温室大棚温度变化的实时监控,提高环境温度测控的精度和效率,是现代种植业科学生产的要求。此系统采用嵌入式微处理器AT91SAM7X256作为温度远程监控采集嵌入式系统平台的CPU,通过CAN总线传输分布式温度采集节点数据,并可通过Web对温度进行远程监控,其测温精度在0.5℃以内,具有较好的实用价值和应用前景。

Modern crop science and production required the real-time temperature monitoring of greenhouses and the improvment of the accuracy and efficiency of temperature measurement and control.An embedded microprocessor AT91SAM7X256 was used as the embedded systems collecting CPU of the temperature remote monitoring and control platform,transmitted distributed temperature data through nodes by the CAN bus,and monitored remote temperature through Web.Its temperature measurement accuracy was less than 0.5 ℃.The system has good practical value and application prospect.
