摘要
设计了一种基于DS1922E的高温测量管理系统。通过对系统整体架构的分析和设计,阐述了主机与DS1922E间通过1-Wire总线获取DS1922E的序列码并且对其设置完全访问密码、准备和启动一个温度采集任务、主机停止任务及读取DS1922E采集记录的数据的通信过程,并给出及分析测试结果。DS1922E高温纽扣温度记录器可以在高温、潮湿等恶劣环境下可靠工作,应用前景良好。
A high-temperature measuring and managing system based on DS1922E was designed. Through the analysis and design of the overall system architecture, the communication process between the host and the DS1922E through the 1-Wire bus is obtained, including getting the DS1922E sequence code and setting password for full access, starting a task for temperature acquisition, stopping task, and reading the data collected and recorded by DS1922E. The analysis of the test results is given. The DS1922E high-temperature button logger can work reliably under harsh environments such as high temperature, high humi- dity, etc.
