Light alarm device of security check door

Abstract

The invention discloses a light alarm device of a security check door. The device comprises two door plates connected with a same door head assembly. Each door plate comprises a plurality of mutuallyspliced door plate modules. A sensor module for detecting metal is arranged in each door plate module. Each door plate module is provided with a first light-emitting part and a second light-emitting part which are independent of each other, the sensor module is connected with the first light-emitting part and the second light-emitting part, and the door plate is provided with a control circuit connected with the first light-emitting part or the second light-emitting part and a fixing part for fixing the door plate modules. By adopting the arrangement, the sensor module is used for sensing metal contraband and triggering the first light-emitting part and the second light-emitting part to start working. In addition, the first light-emitting piece or the second light-emitting piece is controlled by the control circuit, so that the first light-emitting piece and the second light-emitting piece cannot work simultaneously and can be replaced with each other through the control circuit, the situation that the security check door cannot work due to damage of the alarm lamp is reduced, and the service life of the security check door is prolonged.

Description

technical field [0001] The invention relates to the technical field of light alarms for security inspection doors, in particular to a light alarm device for security inspection doors. Background technique [0002] The detection gate, also known as the security gate, is a detection device used to detect whether there are metal objects on the body of the person passing through. When the security gate detects metal, it will be displayed in the form of an alarm such as sound or light. The traditional security door consists of two door panels. At the same time, a large coil for transmitting electromagnetic wave signals is installed on the door panels at equal intervals along the height direction, and a small coil for receiving electromagnetic wave signals is installed in the large coil. The position of a large coil is set as a location. And the directions of the electromagnetic wave signals emitted by the large coils of the two door panels of the security inspection door are cons...

AI Technical Summary

Problems solved by technology

[0003] The light alarm device of the existing security door is usually installed at both ends of the security door through which the door panel passes, and is divided into several independent alarm lights along the height direction according to the location of the security door. When a certain alarm light of the door panel is damaged, Although the security gate can achieve the function of detecting metal, the alarm light of the security gate cannot be displayed normally, and there are cases of missed reports

Therefore, in order to improve protection measures, when the alarm light of the security gate is damaged, the security gate is usually deactivated and replaced by a manual security stick, and the security gate is usually used in public places, and the flow of people is large, so manual detection is used It tends to reduce work efficiency and increase the accumulation of human traffic, but the existing security gates do not use multiple sets of warning lights to replace damaged warning lights.
