基于蓝牙传输的智能液位仪设计

Design of Intelligent Liquid Level Meter Based on Bluetooth Transmission

基于单片机的超声波液位仪是以单片机及电容等元件构成的最小系统为核心,以时差法超声波测距原理为理论依据,利用超声波作为测量信号对封闭式或敞开式罐体中的液面高度进行自动检测和数据处理,减少了测量过程中的人工干预,方便了操作人员对液位的实时监控,并通过与手机之间进行通信、保存有关数据,从而更好地对罐体的液位情况进行管理和监控。

Ultrasonic liquid level instrument based on single-chip microcomputer is based on the minimum system composed of single-chip microcomputer and capacitor and so on. It is based on the principle of time-difference ultrasonic distance measurement and uses ultrasonic as the measurement signal for closed or open tanks. The automatic detection and data processing of the liquid surface height reduces the manual intervention in the measurement process,which facilitates the operator＇s real-time monitoring of the liquid level, and communicates with the mobile phone and saves the relevant data, thereby improving the tank body. The level of the situation is managed and monitored.
