摘要
以两个数据通路为例,阐述单总线温度传感器的多点测量方法,说明了数据通路的选择方法,分别给出了读取温度传感器序列号的流程图;系统时间设置功能流程图和写入时间数据的程序;报警历史数据显示流程、报警历史数据显示画面和报警数据分两屏显示的设计思路。
Taking two data paths as an example, the multi-point measurement method for single-bus temperature sensor was expounded, including the data channel selection method, and the flow chart in reading temperature sen- sor＇ s serial number, and that for time-setting function and time and data-writing program, the display program flow chart and the frame of alarm history data as well as the notion of designing alarm data display in two screens.
