Description

Technical Field

[0001] The present invention relates to the technical field of security monitoring devices, and in particular to a security monitoring device for a smart construction site management and control platform. Background Art

[0002] A typical television monitoring system is mainly composed of two parts: front-end equipment and back-end equipment. The front-end equipment usually consists of components such as cameras, manual or electric lenses, pan / tilt heads, protective covers, monitors, alarm detectors and multi-function decoders, and establishes corresponding connections with various equipment in the central control system through wired, wireless or optical fiber transmission media.

[0003] There is a security monitoring device for a smart construction site control platform with a publication number of CN202010877394.4, which discloses: water molecules in the air are adsorbed by a metal rod, which is a porous metal rod, increasing the contact area with the air. The water molecules adsorbed by the metal rod fall into the water-absorbing sponge, and the weight of the water-absorbing sponge increases. At the same time, the first worm 7 drives the second worm to rotate through the first worm wheel, and the second worm drives the first rotating shaft to rotate through the chain. The first rotating shaft drives the convex head to swing through the turntable, and the convex head slides in the slide groove on the baffle to drive the baffle to move upward. The baffle blocks the heat dissipation hole to prevent fog from entering the box and damaging the circuit board in the box, thereby affecting the operation of the circuit board inside the monitoring device. When the first worm descends, it drives the second rotating shaft to rotate, and the second rotating shaft drives the third rotating shaft to rotate through the belt. The third rotating shaft drives the scraper to rotate in a circle through the second turntable, and the scraper brush scrapes and washes the glass cover to prevent fog from adhering to the glass cover and affecting the monitoring of the monitoring equipment.

[0004] When the existing security monitoring device of the smart construction site management and control platform is working, it needs to monitor a certain area, so it needs to monitor within a certain range. The position of the existing monitoring camera is fixed, so the camera monitoring position range is certain. At the same time, when an emergency occurs, it is necessary to manually control the camera and control the direction of the camera, so as to manually control the camera to shoot and record the required position. Therefore, the monitoring equipment is required to have both automated regional monitoring and manual intervention of the camera's shooting angle. For this reason, we propose a security monitoring device for a smart construction site management and control platform. Summary of the invention
