基于STC89C52的远程水位监测实现
|
摘要
随着现代生活智能化的推进,液位的远程检测应用更加广泛。在实际应用现场液位监测点较多、环境复杂,仅仅通过人工值守进行监测不能满足要求,本文结合了无线通信技术、超声波液位监测技术等,设计出了一款基于单片机的远程无线液位监测报警系统。系统具备两个监测点,每个监测点由单片机模块、超声波模块和无线发射模块构成,通过无线发射模块将监测点的数据发送给接收端;接收端单片机实现水位数据的无线接收并显示到1602液晶上,同时可以通过键盘设定液位的报警阈值,当监测的液位超过设定值时,系统自动报警提示。此外系统还具备液位记录功能,能够记录多组液位数据,通过键盘浏览查询数据信息。
With the advancement of modern life intelligence, it has been more widely used in remote detection of liquid level. In practical applications, there are many monitoring points and the complex environment. It can be hard to monitoring by means of manual. Wireless communication technology, ultrasonic monitoring technology and so on has combined in a wireless liquid level monitoring alarm system based on MCU. The system has two monitoring points. Each monitoring point consists of a micro-controller module, an ultrasound module, and a wireless transmitter and receiver module. Sending the data of the monitoring point to the receiving end through wireless transmitting module; the receiving end realizes the wireless reception of data and displays it on 1602. At the same time, the alarm threshold of the liquid level can be set via the keyboard. When the monitored water level exceeds the setting value, the system will automatically alarm. In addition, the system also has a liquid level recording function, capable of recording multiple sets of liquid level data, and browsing through the keyboard.
