Description

Bank security system

Technical Field

The invention relates to the technical field of bank security protection, in particular to a bank security system.

Background

Since a large amount of cash is stored in a bank and the amount of personnel flowing is large, security measures of the bank are particularly important. The most mature security measures are not to install the camera, the camera is used for covering all areas such as an entrance area and a handling area of a bank, and the image of the camera is transmitted to the background for monitoring. The camera monitors clear and bright colors of the picture when the illumination is good, but if the illumination is suddenly dim, the picture of the picture is immediately lost. In particular, when the illuminance in the environment approaches or reaches zero, the camera cannot capture light, and the monitoring picture appears as a snowflake screen which is full of noise. Therefore, people develop an infrared camera, the infrared camera is not influenced by ambient illuminance, and twenty-four hours uninterrupted monitoring can be realized. However, in the use process of the infrared camera, the picture shot at night is not as clear as in daytime, and especially the situation that eyes reflect light and the face is unclear when a human face is shot. For this reason, people add light-supplementing lamps on the infrared camera, but the light-supplementing lamps are usually integrated in a lampshade at the front end of the camera, which is not beneficial to maintenance; in some security systems, the light-compensating lamps are automatically turned on according to the dim condition of the ambient light, and are automatically turned off when the ambient light is restored to a certain brightness value. However, this embodiment is not only energy-intensive, but also lacks practical significance. In addition, some illegal persons can deliberately shield the camera by using the defect of the installation position of the camera, and then illegal actions are implemented, so that the camera loses the monitoring significance under the condition.

In the scheme, the bank security system provided by the invention is mainly improved in the following two aspects.

On the one hand, the on-off driving of the ambient light compensating lamp 300 is improved, and the on-off driving is improved to be started based on detection signals of the human body sensing device and the light sensor, so that the light compensating lamp is only started when the light is dim and a person approaches a bank, and the energy consumption of the light compensating lamp is greatly reduced. The human body sensing device preferably adopts an infrared detector, and a weight sensor detection mode can be arranged at an important entrance of a bank through foundation laying. The linkage module can adopt a common relay module.

On the other hand, under the condition of the arrangement of the field monitoring cameras, an emergency monitoring system 100 is additionally arranged, and in the emergency monitoring system 100, a hemispherical camera is hidden in the shell 110, when a background host detects that the field camera 200 is shielded by foreign matters, a stand-up horse starts the emergency monitoring system 100, so that the hemispherical camera stretches out of the shell 110 to detect the situation, and the purpose of emergency shooting monitoring is achieved. The background host can determine whether the lens of the field camera 200 is blocked or not by adopting the prior art. The hemispherical camera has an autonomous control module and a communication module, and the communication module is used for receiving an instruction sent by the background host, so as to start the lifting device 120, and expose the hemispherical camera from the housing 110. Specifically, the driving motor 1251 is started to rotate the screw 122, and the sliding block 123 moves downward when the screw 122 rotates, so that the hemispherical camera is extended out through the sleeve 124. To ensure axial movement of the slider 123 along the lead screw 122, a guide rail may be added to the housing 110.

Because the existing infrared cameras basically all say that the light supplementing lamp is arranged in the lampshade, the technical problems that maintenance is not facilitated and the luminous quantity is limited exist, and therefore, the invention provides further embodiments, namely:

The pushing mechanism can adopt a micro cylinder.

In the above-described embodiment, the ambient light compensating lamp 300 is formed of a plurality of LED lamps, which are mounted inside the side wall 222 of the top cover 220 of the field camera 200. When the background host detects that someone intrudes into the bank through the human body sensing device and the ambient light is darker, the light supplementing lamps can be started. Meanwhile, the background host sends a third instruction to a third controller of the field camera 200, wherein the third instruction comprises a third instruction for controlling the second electromagnet to release the two side walls 222, a third second instruction for controlling the first electromagnet to be electrified, a third instruction for controlling the pushing mechanism to jack up the two side walls 222, and a third instruction for controlling the stepping motor 225 to operate, so that the stepping motor 225 drives the two side walls 222 to be changed from a horizontal state to an inclined downward state to enable the LED lamp to supplement light towards the direction pointed by the lens. The specific working process is as follows: turning on a light supplementing lamp; controlling the second electromagnet to be powered off to release the two side walls 222, and controlling the first electromagnet to be powered on to enter a magnetic attraction state; when the pushing mechanism is controlled to jack up the two side walls 222 to a certain height, the end face of the connecting shaft 227 is magnetic and is attracted by the first electromagnet at the end part of the rotating shaft 223, so that the connecting shaft 227 and the rotating shaft 223 are connected into a whole; then, the stepping motor 225 is controlled, and the gear mechanism 224 is used to rotate the two side walls 222 by the same angle around the same direction, so that the LED lamps inside the two side walls 222 are all directed to the direction pointed by the lens, and the lens stops.

Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
