Abstract

The invention discloses an intelligent traffic sign board with a filter circuit. The intelligent traffic sign board comprises a sign board body which is provided with an infrared camera, an image processor, a controller, photosensitive diodes, a wireless communication module and a mobile terminal. The photosensitive diodes are connected with the controller, the infrared camera is connected with the image processor which is connected with the controller, and the controller is in communication connection with the mobile terminal through the wireless communication module. A sampling circuit, the filter circuit and an amplifying circuit are sequentially connected between the photosensitive diodes and the controller. The filter circuit comprises an operational amplifier A1, a capacitor C1, a capacitor C2 and a capacitor C3. The intelligent traffic sign board solves the problem that when light is not sufficient, the traffic sign board can not be easily seen.

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...
