摘要
采用主程序加子程序的模块设计方式 ,完成了电容式智能湿度仪的的软件设计 ,介绍了系统主程序和主要子程序的流程框图。在该软件的支持下 ,湿度仪可自动根据一次仪表信号 ,对环境相对湿度 (RH)进行实时监测、越限报警 ;可经键盘修改RH上、下限的设定值 ;可经键盘发出指令 。
Using manner of chief program and subprogram module,the software design is finished for the capacitance intelligent humidometer.The flow charts of chief program and main subprograms for the system are introduced in the paper.The humidometer can automatically monitor real time relative humidity (RH) of surroundings and give an alert when the RH limit is exceeded according to its sensor signals.Using the keyboard,we can alter the given upper limit and lower limit of RH,have printed real time RH and showed temperatures of surroundings.
