摘要
以工业用测量液罐液位为例,应用GSM通信技术,以STC89S52为控制核心,通过发送短消息远程控制无线数传模块(DTU)发送指令,来控制超声波测距模块进行测距,并将测试结果以短信的形式返回到手机显示。
In this paper, we take the industrial measuring tank level for example, using GSM com- munication technology, with AT89S52 as the con- trol core to control the DTU to send instruction, then the ultrasonic ranging module executes the in- struction to range, the test results will be displayed on the mobile phone in the form of message.
