Abstract

The invention discloses an intelligent traffic signboard with a filter circuit, which comprises a signboard body, an infrared camera, an image processor, a controller, a photosensitive diode, a wireless communication module and a mobile terminal are arranged on the signboard body, and the photosensitive The diodes are all connected to the controller, the infrared camera is connected to the image processor, the image processor is connected to the controller, and the controller is connected to the mobile terminal through a wireless communication module; between the photosensitive diode and the controller The sampling circuit, the filter circuit and the amplifier circuit are connected in sequence; the filter circuit includes an operational amplifier A1, a capacitor C1, a capacitor C2 and a capacitor C3. Solved the problem that it is easy to not see the traffic signs when the light is insufficient.

Description

technical field [0001] The invention relates to an intelligent traffic sign board with a filter circuit. Background technique [0002] At present, cars have become an important means of transportation for people to travel. my country's road construction is also booming, and many traffic signs are set on the expressway to guide the driver's direction of travel. However, when the light is insufficient at night, it often occurs that the sign is not noticed, resulting in missing the exit. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and propose an intelligent traffic signboard with a filter circuit, so as to avoid the advantage that the traffic signboard is easily invisible when the light is insufficient. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An intelligent traffic sign board with a filter circuit, comprising a sign board body, an infrared ca...
