Traffic light display system with amplifying circuit

Abstract

The invention discloses a traffic light display system with an amplifying circuit. The traffic light display system with the amplifying circuit comprises a traffic light post, wherein a WiFi hot point, a controller, a mobile terminal and a first wireless communication chip are arranged on the traffic light post, the WiFi hot point and the first wireless communication chip are both connected with the controller, a pressure sensor is arranged on a road around the traffic light post and is connected with a second wireless communication chip arranged at the roadside through a wire, the first wireless communication chip is in communication with the second wireless communication chip, the mobile terminal is in communication with the controller through the WiFi hot point, a sampling circuit, a filter circuit and the amplifying circuit are sequentially connected between the pressure sensor and the second wireless communication chip in series, and the amplifying circuit comprises a triode T1 and an operational amplifier A1. By the adoption of the traffic light display system with the amplifying circuit, the problems that the state of a traffic light can not be seen and waiting is needed are solved.

Description

Technical field [0001] The invention relates to a traffic light display system with an amplifying circuit, which is specifically applied to traffic light intersections where vehicles have a long queue. Background technique [0002] At present, cars have become a part of people’s lives and play an important role in traffic. At present, large vehicles often block the vehicles behind at traffic light intersections. At some busy intersections, the queues of vehicles are relatively long, making the vehicles behind them invisible. To the state of the traffic light. Moreover, in some cities, the traffic lights do not show the time and other problems. When the waiting time is long, the driver is prone to irritability, and the phenomenon of running lights may occur. Although the traffic lights in some cities cannot display the time, their control centers still control the traffic lights by time. Summary of the invention [0003] The purpose of the present invention is to provide a traffi...
