Embodiment Construction

[0035] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] figure 1 Provided is a functional block diagram of the wireless communication terminal device involved in the present invention. The device includes the following main functional units:

[0037]1) The CPU is the main control unit of the device, in which a set of software codes based on a real-time operating system (RTOS) is running. This unit completes the initialization and function control of other functional units, and completes data exchange with other units through the data bus.

[0038] 2) The Synchronous Dynamic Random Access Memory (SDRAM) and Flash Memory (Flash) units are responsible for storing service data and software codes and can be called by the CPU unit. They are connected to the CPU unit via a parallel data bus.

[0039] 3) The storage unit is responsible for storing large-capacity data read from external connected...

Abstract

The invention provides a method, a device and a system for realizing vehicle wireless communication. A vehicle wireless communication device is allocated on a vehicle and connected with other vehicle equipment through interfaces to support a first wireless network and a second wireless network; meanwhile, a background application subsystem connected with an Internet network is allocated; by implementing the method of the invention, the vehicle wireless communication device can automatically finish high-capacity data switching between the vehicle equipment and the background application subsystem through the first wireless network; and the vehicle wireless communication device transmits a state report and service data to the background application subsystem through the second wireless network when an emergency occurs. By applying the method and the system, vehicle ticket checker transaction data acquisition, centralized vehicle monitoring data uploading, periodic vehicle advertisement data downloading and updating and other vehicle data services can be more conveniently realized.

Description

technical field [0001] The present invention relates to a vehicle wireless communication method and system, in particular to a vehicle wireless communication method and system for public transportation. Background technique [0002] Urban public transport is an important infrastructure in the city. It is responsible for the daily travel tasks of citizens and is closely related to the lives of the general public in the city. With the increasing urban population in our country, the public transportation is becoming increasingly busy. Although the government has continuously invested a large amount of funds in the field of urban infrastructure in recent years, the urban public transport system still has some problems that need to be improved. for example: [0003] Although the use of the bus card system realizes the automation of ticket purchase, ticket inspection, billing, charging, and statistics, which brings convenience to passengers and bus companies, it is still inconve...
