由于灌区自然环境恶劣，观测点多且布局分散。为了分析灌区水量调配对温湿度监测的需求，设计开发了一种基于CAN总线和MSP430单片机相结合的低功耗温湿度采集系统。温湿度信号采集采用SHT10数字温湿度传感器，通过SPI总线技术与控制器进行通信，并引进CAN总线通信技术实现终端数据的传输。相比其他总线技术，CAN总线具有抗干扰能力强、数据的传输速率高、传输距离远、可靠性及性价比高等优点。设计中拟采用Microchip公司生产带SPI接口的CAN控制器MCP2515为CAN通信模块。

Due to the harsh natural environment in irrigated area,there are many observation points and the distribution is scattered,to analyze the requirements of water allocation for temperature and humidity monitoring,a temperature and humidity data acquisition system with low power consumption based on the combination of CAN bus and MSP430 microcontroller is de-signed and developed. The temperature and humidity signal is collected by using SHT10 digital temperature and humidity sensor, and communicates with the controller through SPI bus technology. CAN bus communication technology is introduced to realize the terminal data transmission. Compared to other bus technologies,CAN bus has the advantages of strong anti-interference ability, high data transmission rate,long transmission distance,high stability and low price. CAN controller MCP2515 with SPI inter-face of the Microchip is adopted as CAN communication module in the design.
