Abstract

The invention discloses an intelligent traffic signboard with a sampling circuit, which comprises a signboard body on which an infrared camera, an image processor, a controller, a photosensitive diode, a wireless communication module and a mobile terminal are arranged. 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 Connect sampling circuit, filter circuit and amplifying circuit successively; Described sampling circuit comprises operational amplifier A1, and the noninverting input end of described operational amplifier A1 is connected with one end of resistance R1, and the other end of this resistance R1 is grounded, and described operational amplifier A1 The capacitor C2 is connected in series between the non-inverting input terminal of the amplifier A1 and the output terminal of the operational amplifier A1. 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 sampling 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 sampling 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 signboard with a sampling circuit, comprising a signboard body, an infrare...
