Embodiment Construction

[0018] Such as figure 1 As shown, the vehicle-mounted GPS-based ubiquitous traffic detection system and method are composed of a vehicle-mounted GPS terminal subsystem, a mobile communication subsystem, a data center subsystem, and a traffic information processing center subsystem. The data center subsystem is connected to the vehicle-mounted GPS terminal subsystem through the mobile communication subsystem, and the traffic information processing center subsystem is connected to the data center subsystem through a DNN dedicated line.

[0019] The GPS receiver in the vehicle-mounted GPS terminal subsystem, the GPRS communication module and the touch screen are connected with the single-chip microcomputer. The GPRS communication module is recommended to adopt the MC56 industrial communication module of SIEMENS Company, and the single-chip microcomputer can adopt the single-chip microcomputer PIC16F873. The GPS receiver is responsible for communicating with the satellite to obtai...

Abstract

The invention relates to a vehicle-mounted GPS-based ubiquitous traffic detection system and method, belonging to the traffic field. The system consists of a vehicle-mounted GPS terminal subsystem, a mobile communication subsystem, a data centre subsystem and a traffic information processing centre subsystem, wherein vehicle positioning data collected by the vehicle-mounted GPS terminal subsystem is transferred to the data centre subsystem in real time through the mobile communication subsystem and then analyzed and processed by the data centre subsystem so as to obtain real-time road traffic information, and the real-time road traffic information is sent to the vehicle-mounted GPS terminal subsystem through the mobile communication subsystem. Simultaneously, the real-time traffic information is sent to the traffic information processing centre subsystem every three to five minutes, the condition of traffic flow is predicted through a central computer by utilizing the real-time traffic information and historic traffic information, and traffic flow predicting information is sent to users. In the invention, traffic detection equipment is a motor vehicle-mounted GPS device, and the ubiquity, accuracy and instantaneity of data acquisition are improved in comparison with the prior art that data in traffic detection roots in a fixed detection device.

Description

technical field [0001] The invention relates to the field of ubiquitous network and wireless communication, in particular to vehicle-mounted GPS and traffic detection technology, in particular to a vehicle-mounted GPS-based ubiquitous traffic detection system and method. Background technique [0002] In the prior art, the road traffic detection system cannot accurately and reliably detect vehicle traffic dynamic information in a full range in real time. The main manifestations are: the traffic detector is fixedly installed in the specific location of the road, and can only detect the road traffic information in a local area; some moving vehicles also upload GPS information to the data center, but because they cannot exchange real-time road traffic information services, Therefore uploads are limited and information is not reliable. Invention content: [0003] The object of the present invention is to provide a kind of ubiquitous traffic detection system and method based on...
