Furthermore it is also possible to use multiple ultrasonic detecting equipments to replace the multiple infrared detection equipment, it is described more
A ultrasonic detecting equipment is arranged in toilet, and the top of corresponding urinating bucket is arranged in each ultrasonic detecting equipment,
It is detected for the front to corresponding urinating bucket with the presence or absence of object.
Since ultrasonic wave directive property is strong, energy consumption is slow, and farther out, thus ultrasonic wave is frequent for the distance propagated in the medium
It can be realized by ultrasonic wave for the measurement of distance, such as rangefinder and fill level measuring device.It is past using ultrasound examination
Toward relatively rapidly, conveniently, calculate it is simple, be easy to accomplish real-time control, and industrial requirements can be reached in terms of measurement accuracy.
In order to study and utilize ultrasonic wave, people have designed and have been made many supersonic generators.Generally speaking, surpass
Sonic generator can be divided into two major classes: one kind is with electrically generating ultrasonic wave, and one kind is mechanically to generate ultrasound
Wave.It electrically include piezo-electric type, magnetostriction type and power type etc.;Mechanical system has jar (unit of capacitance) system flute, the liquid whistle and air-flow siren
Deng.The frequency of ultrasonic wave caused by them, power and acoustic wave character are different, thus purposes is also different.At present compared with
For the most commonly used is piezoelectric-type ultrasonic wave producers.
Piezoelectric-type ultrasonic wave producer is actually using the resonance of piezo-electric crystal come work.Inside supersonic generator
There are two piezoelectric chip and a sounding boards.When his the two poles of the earth applying pulse signal, frequency is equal to the intrinsic vibration of piezoelectric chip
When swinging frequency, piezoelectric chip will resonate, and drive resonance panel vibration, just generate ultrasonic wave., whereas if between two electrodes
Compressing piezoelectric chip is vibrated when sounding board receives ultrasonic wave, converts mechanical energy into electric signal by non-applied voltage,
At this moment he just becomes ultrasonic receiver.
Using porch image spot analysis system of the invention, for the difference of public restroom urinating bucket in the prior art
Arrangement influences the technical issues of visual field Shielding plan design, by being handled respectively each urinating bucket, to be based on
The currently used state of each urinating bucket, it is more crucial in porch there are the stretching, extension for when personnel, deciding whether to carry out shielding baffle
, in the detection pattern to porch personnel, using the noise reduction amplitude customizing mechanism based on image maximum resolution, Yi Jitong
The data analysis to the multiple image in prefixed time interval is crossed, the maximum component of amplitude of variation is determined, based on determining component
Correspondence image, the search operation of target shape is carried out, to solve above-mentioned technical problem.
