摘要
设计了利用LabVIEW和AT89C52单片机实现的温度采集与监控系统,采用单总线DS18B20作为温度传感器,将温度的变化转变为数字信号,由单片机通过串口送入计算机,LabVIEW作为开发平台,利用VISA调用串口程序读取数据,对采集到的温度数据进行实时处理、显示、存储与报警,详细介绍了系统的硬件电路和软件设计方案。
Temperature acquisition and monitoring system was designed based on LabVIEW and single chip microcomputer AT89C52. The system used 1-wire digital temperature sensor DS18B20 to acquire the temperature information. When the temperature changed,the digital signals from DS18B20 were also changed. These digital signals were sent to the computer through the serial port of microcontroller. Using LabVIEW software as development platform and using VISA in LabVIEW function library,the temperature data was processed,displayed and stored. As the temperature was over the one set in advanced,the system will give an alarm.The hardware circuits and software project were introduced in detail.
