Description
Technical field
The present invention relates to smart city field more particularly to a kind of users for detecting the safety-type well lid illegally agitated
Method.
Background technique
Well lid, it has also become each Name card of city.It, which is started from, solves actual detailed problem, and becomes one because workmanship is exquisite
Art, last constantly widespread development is at a kind of special culture.Almost Japan each city, can see it is motley under
Water channel well lid is printed on animal, landscape, history story or city characteristic above, is rich in design sense.
1985, Japan's construction saved an official for the concern for causing the common people to drainage, had initiated well lid design
Contest allows the well lid in common people's design city.As a result cause the civil well lid of Japan and design upsurge, not rare place is ad hoc to be set
Meter even becomes the business card in city.According to the investigation of " well lid of Japanese society " art, the well lid that Japan has had more than 6000 kinds is set
Meter, or even establish several well lid museums.Japan establishes one quasi official " well lid association ", by 32 company's groups
At, be responsible for specially protect and study all Japan well lid, have also appeared many " well lid bean vermicelli group ", they set up the group of oneself
It knits, website, forum.For example many young men of Japan are keen to collect well lid picture, tissue is the theme the city of route with well lid
Plan is walked cruelly, is sought treasured generally, is found one and take a picture, then share on the net.
While well lid brings convenient and beautiful, there is also certain to imply, and due to the defect of well lid design, leads
Well lid is caused to be easy to be walked by sled, and the illegal operation agitated is difficult to real-time detection, to bring biggish economy to city management side
Loss.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of application method of safety-type well lid for detecting and illegally agitating,
The scene that well lid agitates can be carried out in illegal person, the detection and alarm to the behavior that agitates can be realized, thus to illegal point

Number.
Then, continue to carry out the specific structure for detecting the safety-type well lid illegally agitated of the invention further
Explanation.
It is described to include: for detecting in the safety-type well lid illegally agitated
Live buzzing equipment is connect with the identity analysis equipment, for receiving the non-checking signal of the identity, is sent out
The buzzer of predeterminated frequency is out to realize alarm operation；
It is described to be used to detect in the safety-type well lid illegally agitated:
It is eliminated in equipment in the region, the area of each connected region is with the sum of its pixel for including come table
Show.
It is described to be used to detect in the safety-type well lid illegally agitated:
The preset area threshold value, which is that the color analysis image level resolution ratio is vertical with the color analysis image, divides
3/1000ths of the product of resolution.
It is described to be used to detect in the safety-type well lid illegally agitated:
When the color analysis image level resolution ratio and thousand points of the product of the color analysis image vertical resolution
Three be non-integer when, to the product of the color analysis image level resolution ratio and the color analysis image vertical resolution
3/1000ths be rounded after the value that obtains as the preset area threshold value.
It is described to be used to detect in the safety-type well lid illegally agitated:
The well lid body frame structure further includes temperature measuring set, and the lower surface of the square is arranged in, described for measuring
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 also used to when receiving the authentication signal, without any buzzing
The sending of sound operates.
In addition, in the well lid body frame structure, the ultrasound including ultrasonic transmitter, ultrasonic receiver, microcontroller
The ultrasonic distance measurement 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
Calculate distance (s) of the launch point away from barrier, it may be assumed that 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 it is known that measurement sound wave encounters barrier after transmitting and is reflected back
Come time, according to transmitting and the received 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 distance measurement, it is necessary first to root
The aerial spread speed of ultrasonic wave is calculated according to ambient temperature.
Ultrasonic distance measurement 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.
Using of the invention for detecting the safety-type well lid illegally agitated, for well lid in the prior art agitate behavior without
The technical issues of method onsite alarming, on the one hand, establish the recognition mechanism based on image procossing, wherein according to the level of image
The product of resolution ratio and vertical resolution determines the area of reference threshold value for executing that smaller area is eliminated in image, to improve figure
As the adaptive level that region is eliminated, also by the analysis of the color component to image to be processed, select it is different with it is described to
The adaptable histogram equalization mode of image is handled, the flexibility of histogram equalization processing is improved, on the other hand, is introduced
Illegally agitate alarm mechanism based on what well lid body frame structure ontology built well lid itself, also introduce height change detection pattern and
Identity analysis mode, to realize the onsite alarming that well lid agitates.
It is understood that although the present invention has been disclosed in the preferred embodiments as above, above-described embodiment not to
Limit the present invention.For any person skilled in the art, without departing from the scope of the technical proposal of the invention,
Many possible changes and modifications all are made to technical solution of the present invention using the technology contents of the disclosure above, or are revised as
With the equivalent embodiment of variation.Therefore, anything that does not depart from the technical scheme of the invention are right according to the technical essence of the invention
Any simple modifications, equivalents, and modifications made for any of the above embodiments still fall within the range of technical solution of the present invention protection
It is interior.
