Problems solved by technology

[0005] The existing intelligent bus stop sign system based on GPS global positioning, through the extended GPS function provided by the system, real-time satellite positioning of the bus, although the current position, speed, direction and other information of the bus can be grasped in real time, but based on GPS The global positioning system architecture is complex, expensive and poor in flexibility, and there are many high-rise buildings in the city, and the satellite signal in some areas is not smooth, so it affects popularization. Currently, only megacities have trials

Embodiment Construction

[0020] The block diagram of the circuit structure of the bus station arrival information display board based on ZigBee is as follows: figure 1 shown, including:

[0021] The on-board controller (1) of the bus, the controller between bus stops (2), and the bus station controller (3); the on-board controller (1) is composed of a radio frequency communication CC2530 module and an odometer sensor, and the bus odometer sensor The output signal is connected to the I / O port of the 8051 microprocessor in the CC2530 module, which is directly read by the 8051 microprocessor and stored in the flash memory in the CC2530 module chip. The radio frequency communication uses a 2.4GHz inverted F antenna designed by TI. Increase the communication distance. Both the bus station controller (2) and the bus station controller (3) are composed of a radio frequency module and an LCD display, wherein the radio frequency module is a CC2530 module, and the LCD display is connected to the I / O port of th...

Abstract

The invention relates to a bus station-arriving information display board based on ZigBee. The bus station-arriving information display board is characterized in that each bus station forms a bus station-arriving information query system; CC2530 radio frequency communication modules are adopted between buses in the driving process as well as between the bus station and the bus for transferring information to the front bus station; when the number of buses between the two bus stations is fewer, and the communication between the bus stations is difficult, the CC2530 radio frequency communication modules are used for completing the communication between the bus stations of a bus line.

Description

[0001] (1) Technical field: [0002] Each bus station constitutes a bus arrival information query system, and the CC2530 radio frequency communication module is used to transmit the information to the front bus station between the driving buses and between the bus station and the bus. When it is difficult to complete vehicle-to-vehicle communication, the CC2530 radio frequency communication module is used to realize communication between bus line stations. [0003] (two) background technology: [0004] With the vigorous development of the public transport industry, more and more people start to travel by bus, and the urban bus lines increase rapidly with the development of the public transport industry, so the roads are becoming more and more congested, and the time for passengers to wait for the bus becomes very uncomfortable. It is sure that some buses are very crowded and some buses have few passengers. Because the crowded buses take a long time to get on and off, each stop ...
