Abstract

The invention discloses a prompting system for arrival of a bus at a bus stop. The system is composed of a camera display device, a bus, setting devices, a central controller, a driver monitoring device, and door display devices. The setting devices and the door display devices are arranged at a front door and a rear door of a bus; electronic tubes are arranged at the central controller and the driver monitoring device; and thus the central controller processes received information and transmits the processed information to the door display devices and the driver monitoring device, and a driver informs passengers of getting off the bus or controlling the bus by the camera display device. At least more than two buttons are arranged at the setting devices; and light-emitting tubes and sensors are arranged inside the buttons. A device with digital number and stop integration is arranged at the central controller; the information is transmitted to the door display device and the driver monitoring device. Liquid crystal display screens are arranged at the door display devices and a digital device is arranged at the driver monitoring device, so that passengers and drivers can carry out communication. The system has advantages of simple structure, great convenient and practical effects, and low cost.

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, ...
