摘　　要：为了补偿环境温湿度对望远镜系统的不利影响,提高大型光电望远镜的成像能力,设计了一种基于CAN总线的温湿度监测系统。系统采用总线式拓扑结构,主要由数字式传感器SHT15、C8051F500单片机、CAN总线以及上位机组成;单片机与传感器之间利用SMBus进行通信,单片机读取传感器数据后,经由CAN总线将数据传送到上位机,上位机实时处理显示温湿度信息;系统设计完成后在实验室中进行了验证实验,成功读取了两个节点的传感器采集到的数据,能够进一步应用于实际工作中。In order to compensate the negative impact of the environment temperature and humidity on the telescope system,improve the capability of large optoelectronic telescope,a temperature and humidity monitoring system based on CAN field-bus was designed.The system adopts the bus topological structure,mainly consist of the digital sensor SHT15,C8051F500single-chip microcomputer（SCM）,CAN field-bus and the upper unit.The SCM communicates with SHT15 through SMBus,when the SCM gets the temperature and humidity information from the sensor,it will transfer these messages to the upper computer through the CAN.The upper computer is in charge of processing and displaying these messages timely.The system has been verified in experiments and two node-sensors＇ data was collected successfully,it can take a further application in practical work.
