The Design of Automatic Bus Station-Informer
This article introduces a new methde to design the bus-stop reporting system。It provides a new scheme ,which is based AT89C52 microcomputer，to control the display of the LED lattice。 The system mainly through AT89C52 as the core system, controls keyboard’s input and LED’s display . The entire system through manual operation after receiving the keys to a system scan button press, Key subcontractors that determined a signal to the microcontroller, then the micro-processing of signals from the accrued value added to determine the reliability of station names. Driving through the scanning from the LED display by the arrival station names. Reached semi-automatic stations role. The entire system includes some modules ;for example， the key subcontractors, the signal input microcontroller, signal processing, LED Drivers and LED display program. LED display is the focus of the system.
The system can greatly enhance bus stations accuracy, and improve the quality of service of the transportation system. It will promote the city's economic development and the harmonious development of traffic.
