Problems solved by technology

[0004] In order to solve the technical problem that the running state of the safe passage indicator light cannot be automatically operated on the stage, the present invention provides a safety passage indicator light operating state verification mechanism, which adopts a high-precision image recognition mechanism to locate the safe passage light indicator and identify the safety icon. Searching, when the safety icon is not found, send an indicator light failure signal to remind the relevant management personnel to carry out the corresponding maintenance of the safety icon; determine the intensity of feature deepening processing for the captured image based on the dynamic range of

Embodiment Construction

[0030] The following will describe in detail the implementation of the safe passage indicator light operating state verification mechanism of the present invention.

[0031] The safety passage indicator light is suitable for fire emergency lighting. It is the most common lighting tool in fire emergency. It is made of industrial plastic and high-brightness bulbs. The color is mainly white, and there are two arrows on the surface. The fire emergency lights have a long emergency time, high brightness, and have an automatic emergency function when power is off. Fire emergency lights have wall-mounted, portable, and hanging installation methods. Fire emergency lights have the characteristics of reliable operation, high stability, low power consumption, high brightness, and long service life. There are power switches and indicator lights on the side, and they are widely installed in corridors and fire exits in public places.

[0032] In order to overcome the above-mentioned shortco...

Abstract

The present invention relates to a secure channel indication lamp operation state certification mechanism. The mechanism comprises: a secure channel indication lamp arranged above a secure channel ofa stage and configured to display a secure icon corresponding to the secure channel by employing a green background to indicate the position of the secure channel to audiences; a control switch connected with the secure channel indication lamp and arranged above the secure channel of the stage and configured to control the on or off of the secure channel indication lamp; a scene video mechanism configured to perform video operation facing the secure channel of the stage to obtain and output a corresponding secure channel entrance image; and a brightness extraction device connected with the scene video mechanism and configured to emit scene transfer signals when the difference of the whole brightness value of the secure channel entrance image and the whole brightness value of the standard scene image exceeds a preset brightness difference threshold value. The efficiency of stage device certification is improved.

Description

technical field [0001] The invention relates to the field of equipment maintenance, in particular to a mechanism for verifying the operating state of a safe passage indicator light. Background technique [0002] The working principle of the safety channel indicator light: there are two sets of power supply systems inside, one is the internal battery to supply power to the lighting lamp, the other is an external power supply to supply power to the lighting lamp and charge the battery at the same time, and there is a power conversion mechanism, when the external power supply is disconnected (Power outage), the line will switch to the way of battery power supply. In this way, the indicator light will remain illuminated when the power supply of the indicator light is disconnected. The indicator lighting system is mainly of the self-contained power supply independent control type. The normal power supply is connected to the ordinary lighting power supply circuit, and the battery...
