specific Embodiment approach 1

[0039] A public security monitoring anti-frost system disclosed in this embodiment combines figure 1 and figure 2 As shown, it includes a camera, a central switch and a monitoring computer, and the camera is connected to the monitoring computer through the central switch. It is characterized in that the camera includes a monitoring component 1, and the outside of the monitoring component 1 is provided with a spherical rotatable frost cover 2 , the upper end of the anti-frost cover 2 is provided with a defrosting assembly 3, the camera is also provided with an environmental monitoring assembly 4, the environmental monitoring assembly 4 includes a temperature sensor and a dew point sensor, and the temperature sensor and the dew point sensor pass through the center The exchange opportunity monitors the computer connection, and judges the current weather conditions through the computer; when the environmental monitoring component 4 detects frosty weather, the anti-frost cover 2 d...

specific Embodiment approach 2

[0048] This embodiment is based on the specific implementation mode 1, specifically, in combination with figure 1 As shown, the rotating shaft of the rotating motor 22 is provided with gears, and the inner wall of the rotating shaft 21 is provided with ring teeth, and the gears mesh with the ring teeth.

specific Embodiment approach 3

[0049] This embodiment is based on the specific implementation mode 1, specifically, in combination with figure 2 and image 3 As shown, the first photoelectric sensor 52 includes two photoelectric sensors arranged at intervals. Compared with one sensor, the two photoelectric sensors arranged at intervals can detect the edge position of the hollow groove 111, and the two sides of the hollow groove 111 in the circumferential direction can be As the reset point, when the position plate 11 rotates to the edge of the hollow groove 111, the pendulum block 31 is in a vertical state, the position contact 311 is between the second photoelectric sensor 34 and the third photoelectric sensor 35, and the two heating strips 33 are both In the closed state, it is judged that it is at the edge of the hollow groove 111 according to the different states of the two photoelectric sensors.

Abstract

The invention belongs to the technical field of the monitoring equipment, and especially relates to a public security monitoring frost prevention system. The system comprises cameras, a center switchand a monitoring computer; the cameras are connected with the monitoring computer through the center switch; each camera comprises a monitoring assembly, a spherical rotatable frost prevention cover is arranged at the external of the monitoring assembly, a frost removing assembly and an environment monitoring assembly are arranged at the upper end of the frost prevention cover. Distinguished fromthe existing fixed protection cover, the frost prevention cover can slowly rotate when detecting the frost weather, the frost is removed through the frost removing assembly at the top of the frost prevention cover; the frost removing assembly can be arranged at the blind area of the top monitoring assembly by adopting the rotatable protection cover; the condition that the camera is shielded due tothe movement of the frost removing assembly in the frost removing process can be avoided; and a way for removing frost through heating at the external of the frost prevention cover is adopted, the condition that the monitoring of the camera is shielded since the steam produced due to excessive internal temperature of the frost prevention cover is condensed on the inner surface of the frost prevention cover is avoided.

Description

technical field [0001] The invention belongs to the technical field of monitoring equipment, in particular to a public security monitoring anti-frost system. Background technique [0002] At present, closed-circuit monitoring is widely used in civil and commercial fields. Since surveillance cameras are usually installed in outdoor environments, rain, snow, sand and dust in outdoor environments are likely to affect the monitoring effect. In order to ensure the quality of monitoring and the life of monitoring equipment, Usually, a protective cover is set outside the monitoring equipment. The protective cover can effectively block rain, snow, sand and other external debris, and prevent rainwater from entering the corrosion equipment. For most civil and commercial monitoring, the protection of the protective cover can meet the monitoring needs. , but for the public security monitoring system, the requirements for monitoring quality are relatively higher. In frosty weather, frost...
