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

[0019] The block diagram of the circuit structure of the bus stop information display board based on WI-FI is as follows: figure 1 shown, including:

[0020] The on-board controller (1), bus station controller (2), and inter-bus station controller (3) of the bus; the on-board controller (1) is composed of a serial port Wi-Fi module and an odometer sensor, and the serial port Wi-Fi The module adopts the RN-171 module, and the output signal of the odometer sensor is sent to the I / O port of the microprocessor in the RN-171 module through the level conversion circuit and the low-pass filter circuit. The on-board controller of the bus (1) is used for bus RF communication between vehicles and between buses and bus stops. Both the bus station controller (3) and the bus station controller (2) are composed of a serial port Wi-Fi module and an LCD display. The serial port Wi-Fi module adopts the RN-171 module, and the communication data is stored in the memory of the RN-171 module. Th...

Abstract

The invention provides a bus arriving information inquiry system composed of each bus station. Information is transmitted to a bus station ahead between buses and between the bus station and the bus by adopting a serial port WiFi (Wireless Fidelity) module; each 2 to 4 bus stations are accessed into an Internet communicated controller between the bus stations through serial port WiFi; and other bus stations between the two bus stations finish information exchange between the bus stations through communication between the buses.

Description

[0001] (1) Technical field: [0002] Each bus station constitutes a bus arrival information query system, between the bus and between the bus station and the bus, the serial port Wi-Fi module is used to transmit the information to the front bus station, and every 2 to 4 bus stations are set The inter-bus station controller connected to the Internet network communication through the serial port Wi-Fi, and other bus stations between the two bus stations, complete the information exchange between bus stations through the communication between buses. [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 h...
