Abstract

The invention discloses a traffic light display system with an amplifying circuit. The traffic light display system comprises a traffic light column, and a WiFi hotspot, a controller, a mobile terminal and a first wireless communication chip are arranged on the traffic light column. The WiFi hotspot and the first wireless communication chip are respectively connected with the controller, a pressure sensor is arranged on a road around the traffic light column and connected with a second wireless communication chip arranged on the roadside through a lead, the first wireless communication chip is connected with the second wireless communication chip through communication, and the mobile terminal is connected with the controller in a communication mode through the WiFi hotspot. A sampling circuit, a filter circuit and the amplifying circuit are sequentially in series connection between the pressure sensor and the second wireless communication chip, and the amplifying circuit comprises an operational amplifier A1, an operational amplifier A2 and a triode T1. The problem that the state of a traffic light and waiting time cannot be seen is 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 crossings where vehicles queue up relatively long. Background technique [0002] At present, automobiles 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, while at some busy intersections, the queues of vehicles are relatively long, making it impossible to see the vehicles behind. to the state of traffic lights. And in some cities, the traffic lights do not display time and other problems. When the waiting time is long, the driver is prone to irritability, and thus the phenomenon of running lights occurs. Although the traffic lights in some cities cannot display the time themselves, their control centers still control the traffic lights by time. Contents of the invention [0003] The object of the present...
