户外终端油位智能监测系统

Intelligent Liquid Level Monitoring SystemFor Outdoor ermination

户外终端油位智能监测系统使用超声波对封油高度进行检测，频率高波长短、绕射现象小，另外方向性好，能够成为射线而定向传播。超声波在液体、固体中衰减很小，因而穿透能力强，尤其是在对光不透明的固体中，超声波可穿透几十米的长度，碰到杂质或界面就会有显著的反射。利用这一特性可计算封油的高度。该系统使用取电技术对设备进行供电，利用无线信号传输技术进行数据传输，这样在不改变任何施工环境的条件下完成对信号的采集和传输。

The intelligent oil level monitoring system for outdoor terminals uses ultrasonic waves to detect the oil sealing height. It has high frequency, short wavelength, and small diffraction phenomenon. In addition, it has good directivity and can be directed and propagated as a ray. Ultrasonic waves have very little attenuation in liquids and solids, so they have strong penetration ability, especially in solids that are opaque to light, ultrasonic waves can penetrate tens of meters in length, and there will be significant reflections when they encounter impurities or interfaces. This characteristic can be used to calculate the height of the oil seal. The system uses power extraction technology to supply power to the equipment, and uses wireless signal transmission technology to transmit data, so that the signal can be collected and transmitted without changing any construction environment.
