Abstract

A bus arrival reminding system disclosed by the present invention comprises an image pickup display and a bus composed of setters, a central controller, a driver monitor and door edge displays. A front door and a rear door of the bus are respectively equipped with the setters and the door edge displays, and by increasing the electronic tubes on the central controller and the driver monitor, the central controller processes the received information and transmits to the door edge displays and the driver monitor, and a driver notices the passengers to get off or control the vehicle actions via the image pickup display. Each setter is equipped with at least two buttons in which light-emitting electronic tubes and inductors are arranged, and the central controller is equipped with a device integrating the numbers and the stations as one and transmits to the door edge displays and the driver monitor; each door edge display is equipped with a liquid crystal display screen, and the driver monitor is equipped with a digital device, so that a device for the communication of the passengers and the drivers is realized. The bus arrival reminding system of the present invention is simple in structure and low in cost, and is convenient and practical.

Description

technical field [0001] The invention relates to a bus arrival reminder system, in particular to a bus arrival reminder system using fluorescent lamps. Background technique [0002] In the current lighting industry, the existing general-purpose electronic tubes are composed of electrical components such as power capacitors, normally closed thermal switches, and thermal resistance coils. This electronic tube has strong vibration noise and temperature rise, and has light flickering. When the power supply is turned on, the lamp cannot be lighted up quickly, and at the same time, due to the unstable voltage of the mains, the electronic tube and the lamp are easy to burn out, causing losses to the user. [0003] The new electronic tube has been improved in some parts. The circuit includes the AC-DC conversion circuit module, the useless band filter circuit module, the DC-AC inverter circuit module, and the output device. It can reduce vibration noise and control temperature rise, ...
