基于目前土壤温湿度检测及控制通道少,人机交互不友好等问题,研制了一套多通道并行处理的土壤温湿度检测装置。在该装置中,温湿度测量通道数为8个,每个通道由湿度传感器SEN0114和温度传感器DS18B20组成。湿度传感器通过与PCF8591(共2块)连接实现A/D转换,测量数值显示在触摸屏上。通过按键设置温湿度报警值,通过D2822A放大报警信号功率。利用STM32单片机、UCOS操作系统实现多任务的并行处理,每个测量任务具有相同的优先级。基于STemWin进行人机界面的设计,通过任务标志变量TASK_FLAG记录每个任务的状态。装置调试结果表明,系统运行稳定、测量精度高,可应用于土壤温湿度的测量。
