The environment temperature of the lower surface position of square.
And it is described for detecting in the safety-type well lid illegally agitated：
The microcontroller is also connect with the temperature measuring set, for receiving the environment temperature, and is based on the ring
Ultrasonic propagation velocity described in the temperature computation of border；
Wherein, the live buzzing equipment is additionally operable to when receiving the authentication signal, without any buzzing
Sound sends out operation.
In addition, in the well lid body frame structure, include the ultrasound of ultrasonic transmitter, ultrasonic receiver, microcontroller
The ultrasonic ranging principle of wave component is as follows：Ultrasonic transmitter emits ultrasonic wave to a direction, while emission time
Start timing, ultrasonic wave is propagated in air, is encountered barrier on the way and just is returned to come immediately, ultrasonic receiver receives back wave
Just stop timing immediately.The aerial spread speed of ultrasonic wave is 340m/s, according to the time t of timer record, so that it may with
Distance (s) of the launch point away from barrier is calculated, i.e.,：S=340t/2.Here it is so-called time difference telemetrys.Ultrasound
Away from principle to be using the aerial spread speed of ultrasonic wave be is reflected back it is known that measuring sound wave and encountering barrier after transmitting
Come time, according to transmitting and receive time difference calculate launch point to barrier actual range.It can be seen that ultrasonic wave
Range measurement principle and Principles of Radar are the same.
However, in fact, the aerial spread speed of ultrasonic wave is a variable, not according to ambient temperature
Together, the aerial spread speed of ultrasonic wave is also different, therefore, in order to improve the accuracy of ultrasonic ranging, it is necessary first to root
The aerial spread speed of ultrasonic wave is calculated according to ambient temperature.
Ultrasonic ranging is mainly used in the range measurement of reversing prompting, construction site, industry spot etc., although current
Hundred meters can be reached on ranging range, but the precision measured often can only achieve centimetre scale.
