Flash light working condition monitoring method and device thereof

Abstract

The invention discloses a flash light working condition monitoring method and a device thereof used in a road traffic electronic device. The method thereof comprises the following steps of: penetrating a section of conductor in the power supplying loop of the flash light through a current transformer coil, analyzing an electrical signal induced by the current transformer coil, measuring the working state of the flash light and recording the times of the flash actions. The device thereof comprises an inductive choke L, a rectification circuit DL, a filter circuit C1, an operational amplifier IC1 and a single chip microcomputer IC2 which are electrically connected in sequence. The operational amplifier IC1 is also provided with a positive terminal bias voltage dividing resistor R1, a positive terminal bias voltage dividing resistor R2 and a pull-up resistor R3. The proposal is adopted to lead the management staff of the road traffic electronic device to be capable of immediately mastering the working condition of the flash light so as to determine the working state of the flash light, maintain the flash light out of order timely and further ensure the integrity of electrified information.

Description

technical field [0001] The invention relates to a method and a device for monitoring the working condition of a flashlight in road traffic electronic equipment, and belongs to the field of electronic technology. Background technique [0002] With the rapid development of highway traffic, the requirements for traffic management are also increasing. Traffic electronic monitoring has been widely used. Photography and video recording have become important means for traffic violations, traffic accidents, and traffic-related criminal information records. Flash lights play an important role in the photography and video recording of traffic electronic management. However, in the current traffic electronic equipment, there is no device for direct monitoring of the working condition of the flashlight, and whether the flashlight is working is generally acquired on the spot or analyzed in the pictures and images of photographing and video recording. Therefore, there is a lag in underst...

However, in the current traffic electronic equipment, there is no device for direct monitoring of the working status of the flashlight. Whether the flashlight is working or not is generally acquired on the spot or analyzed in the pictures and images of the camera and video.

Therefore, there is a lag in understanding the working conditions of the flashlights, that is, the managers of road traffic electronic equipment cannot grasp the working conditions of the flashlights in real time, and cannot repair the malfunctioning flashlights in time, and finally cause the incompleteness of traffic electronic information, which affects traffic electronics. development of work
