Description

Prevent sheltering from monitoring device and have its monitored control system

Technical Field

The utility model relates to a security protection technical field particularly, relates to a prevent sheltering from monitoring device and have its monitored control system.

Background

With the development of the camera technology and the internet of things technology, security surveillance cameras are widely and deeply applied. In factories, office buildings, stations, and the like, more and more monitoring cameras are provided. The monitoring camera has the advantages of wide monitoring range and labor saving when used for security protection. However, in practical applications, when a lawless person performs an illegal activity, the camera is often shielded to avoid the monitoring of the camera, and an attendant in a monitoring room is not easy to find the lawless person, so that the criminal activity is successful, and no monitoring clue exists, which is not beneficial to the case solving and detection.

The existing monitoring device with the shielding prevention function can give an alarm to a shielding object close to the camera, but an effective monitoring and alarming method is not available for a shielding mode of spraying the camera by using viscous or colored liquid to make the picture of the camera fuzzy, and potential safety hazards exist.

Disclosure of Invention

An object of the utility model is to provide a prevent sheltering from monitoring device and have its monitored control system, can effectively solve current monitoring device and can not prevent the problem of sheltering from.

A shielding-proof security monitoring device comprises a shell and a camera arranged on the front end face of the shell, wherein a plurality of distance sensors are arranged on the front end face of the shell, and the distance sensors are arranged at equal intervals by taking the camera as a center; the front end of camera is equipped with transparent protective glass, transparent protective glass pastes towards the one side of camera and is equipped with and prevents that liquid shelters from the sensor.

Further, prevent that liquid shelters from sensor and include first sensor and second sensor, first sensor and second detector symmetry set up transparent protective glass's upper and lower both ends.

Further, the liquid blocking prevention sensor is an optical sensor or a capacitive sensor.

A monitoring system comprises the shielding-prevention security monitoring device and a monitoring platform connected with the shielding-prevention security monitoring device.

Further, the monitoring platform comprises a display screen for displaying a monitoring picture, an alarm unit for giving an alarm when the anti-shielding security monitoring device finds abnormality, and a control unit for controlling the anti-shielding security monitoring device.

Further, the alarm unit is a buzzer.

Furthermore, the connection mode of the monitoring platform and the anti-shielding security monitoring device is one of WIFI, optical fiber and network cable.

Compared with the prior art, the utility model discloses following beneficial effect has: the solid shielding object close to the camera can be sensed by arranging the distance sensor on the shell; through set up in transparent protective glass and prevent liquid and shelter from the sensor, when not sending out the molecule and spraying liquid to the camera and shelter from the camera, prevent that liquid shelters from the sensor and passes through the light flux or the change of dielectric constant of sensing transparent protective glass to judge that liquid shelters from and send out the police dispatch newspaper through the monitor platform. The utility model discloses can shelter from solid and liquid simultaneously and carry out the police dispatch newspaper, improve the security protection intensity of security protection device's reliability greatly.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in fig. 1, in a preferred embodiment, the utility model discloses a prevent sheltering from security protection monitoring device mainly includes shell 1, camera 2, distance sensor 4, transparent protective glass 3 and prevents that the liquid shelters from sensor 5. Wherein, camera 2 is circular, and it installs the preceding terminal surface at shell 1. The front end face of the housing 1 is provided with a plurality of distance sensors 4 for sensing a blocking object close to the camera 2. In this embodiment, the number of the distance sensors 4 is four, and the distance sensors are arranged at equal intervals with the camera 2 as the center.

Transparent protective glass 3 sets up the front end at camera 2, and during concrete implementation, transparent protective glass 3 accessible draw-in groove or buckle are fixed at the preceding terminal surface of shell 1 to use silica gel to seal between transparent protective glass 3 and shell 1, thereby improve camera 2 leakproofness. One side of the transparent protective glass 3 facing the camera is provided with a liquid shielding sensor 5 for preventing lawless persons from shielding the camera by using liquid.

In order to better prevent the shielding, in this embodiment, the number of the liquid shielding sensors 5 is two, and the two sensors are respectively a first sensor and a second sensor, and the first sensor and the second sensor are symmetrically arranged at the upper end and the lower end of the camera 2.

The liquid-blocking prevention sensor 5 may employ an optical sensor or a capacitive sensor. Optical sensors operate on the principle of refraction of light. When there is no liquid on the transparent protective glass 3, almost all the light is reflected to the optical sensor; when liquid is present on the transparent protective glass 3, a portion of the light is deflected, which causes a change in the amount of light received by the sensor, and thus the presence of liquid is detected. The capacitance type sensor is designed by utilizing the huge difference of dielectric constants of liquid and glass, when liquid exists on the transparent protective lens 3, the dielectric constant of the transparent protective lens 3 changes differently according to the difference of the amount of the liquid contacting with the transparent protective lens 3, and therefore liquid detection is achieved.

Referring to fig. 2, the monitoring system of the present invention mainly includes an anti-blocking security monitoring device 10 and a monitoring platform 20. The monitoring platform 20 is connected with the plurality of shielding-prevention security monitoring devices 10 through WIFI or optical fibers or network cables, and the monitoring platform 20 comprises a display screen 21 for displaying monitoring pictures, an alarm unit 22 for giving an alarm when the shielding-prevention security monitoring devices 10 find abnormality, and a control unit 23 for controlling the shielding-prevention security monitoring devices 10. Wherein, the control unit 23 can adopt the computer, and alarm unit 22 can adopt the bee calling organ, and when the sensing of preventing sheltering from security protection monitoring device 10 had shelter to, prevent sheltering from security protection monitoring device 10 and send out signal to alarm unit 22, thereby alarm unit 22 sends out the police dispatch newspaper and infories security personnel.

While the invention has been described in conjunction with the specific embodiments set forth above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations that fall within the spirit and scope of the appended claims.
