Abstract

A security door with an image acquiring system is disclosed. The image acquiring system constituted with a camera, a display, an image-recording unit and a video output interface is combined with a metal detector as a whole.

Description

 Security gate technology field

 The invention relates to a public safety inspection device, which is a security door with an image acquisition system. Background technique

 A security door, or metal detector, walk-through metal detection security door, etc., consists of a controller inside the beam and a detection coil inside the door frame, which can perform non-contact detection and alarm for the presence of metal objects in the body for discovery. Deliberately hidden metal weapons and other items that threaten public safety. Its role is to inspect the personnel passing through the security gate to ensure that all personnel entering a certain area do not carry metal dangerous goods that threaten the safety of others. One of its typical applications is the security checkpoint of the civil aviation airport. All passengers on the civil aircraft must pass the security check before boarding the aircraft. With the continuous development of society, the application scope of security gates has also been expanded. In addition to airports, security gates are also widely used in security inspections of stations, docks, courts, museums, prisons, detention centers, stadiums, entertainment venues and large public events. .

Video surveillance and recording is another effective means of ensuring public safety. The location where the security door is placed is the entrance and exit for all personnel entering the controlled area. Therefore, obtaining the image of the location of the security door is of great value to the security assurance work. Since the inspected person must enter the controlled area through the security door, obtaining the image of the inspected person from the perspective of the security door itself can provide extremely valuable appearance and behavioral characteristics. However, the general security gate does not have an image acquisition function and cannot meet this requirement. Summary of the invention

 The invention provides a security door which not only has a metal detecting function, but also integrates an image capturing system and can provide image data with reference value.

 The side of the security detector top detector controller beam facing the inspected person of the present invention has a video camera built in on either side of the beam that does not distinguish the direction of entry and exit, and the camera lens faces outward in the direction in which the person comes in, the camera The power required for the work is provided inside the security door, and the entire security door is connected to the external power supply by a power cord. When the security door is working, all the images of the personnel who pass the security check are taken by the camera. The video signal output by the camera is connected to the universal video socket located at the appropriate position on the surface of the controller or the door through the internal cable. The external device provides the image signal captured by the camera, which constitutes an essential part of the image acquisition system.

 The extended configuration of the image acquisition system of the present invention is to add a microphone in addition to the basic part, or to use a camera with a microphone to acquire an on-site sound signal while acquiring an image; and a controller beam housing is also installed In the image recording unit, the video signal and the sound signal obtained by the camera are simultaneously output to the recording unit for recording; on the other side of the controller beam, a display screen is also built in, and the display surface faces outward for real-time display of the image obtained by the camera. , in order to observe whether the image acquired and recorded is normal.

 The image acquisition system of the security door is relatively independent of the metal detection part circuit, and the two are organically combined into a complete security door.

The invention has the beneficial effects that: the metal detection security inspection can be performed, and all the images of the best viewing angle of the security personnel passing through the security inspection channel are obtained and provided to the video monitoring system for use. When the extended configuration is adopted, its own image recording function can provide useful image clues to the public security department after a security incident such as a security incident.

In the figure, '. 1. Security door controller beam, 2. Camera, 3. Image output interface, 4. Display, ^5. Security door parameter setting keyboard, 6. Alarm indication, 7. Video distributor, 8. Image recording unit. detailed description

 In Fig. 1 and Fig. 2, a camera (2) facing the direction in which the inspected person comes in is mounted on one side of the security door controller beam (1), and an image of the person is obtained, and the image is received by the video distributor (7). Divided into multiple signals, one of which is transmitted in real time to the output interface (3) for use by an external video surveillance system. At the same time, the video signal of the image is also transmitted to the other side of the beam (1) mounted on the security door controller. The display (4) is displayed and recorded by the image loop recording unit (8) installed in the controller beam. The power required for each of the above parts is provided by the security door. The image acquisition system that forms the security door is combined with the metal detection part to form a complete security door. The security door is connected to the external power supply by a power line. In this embodiment, the image acquisition system of the security door is set to work automatically. After the security door is turned on, the system automatically enters the recording state to ensure that all images in the working state of the security door are obtained.
