Abstract

The invention discloses an intelligent traffic sign board with an amplifying circuit. The intelligence traffic sign board with the amplifying circuit comprises a sign board body. An infrared camera, an image processor, a controller, photosensitive diodes, a wireless communication module and a mobile terminal are arranged on the sign board body. The photosensitive diodes are connected with the controller. The infrared camera is connected with the image processor. The image processor is connected with the controller. The controller is in communication connection with the mobile terminal through the wireless communication module. A sampling circuit, a filter circuit and the amplification circuit are connected in sequence between the photosensitive diodes and the controller. The amplifying circuit comprises an operational amplifier A1, an operational amplifier A2 and a triode T1. By the adoption of the intelligence traffic sign board with the amplifying circuit, the problem that when light is insufficient, people often cannot see the traffic sign board is solved.

Description

technical field [0001] The invention relates to an intelligent traffic sign board with an amplifying 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 an amplifier 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 an amplifying circuit, comprising a sign board body o...
