Intelligent traffic system and monitoring control method thereof

Abstract

The invention discloses an intelligent traffic system and a monitoring control method thereof, belonging to the technical fields of traffic system optimization and monitoring control. In the invention, the intelligent traffic system is divided into n Zigbee network modules with the same structure, every Zigbee network module comprises m fixed nodes with the same hardware structure, every platformand every intersection are respectively provided with a fixed node, and every bus is provided with a vehicular moving node. The method adopts the technical scheme that a center node is established inevery Zigbee network module to manage the Zigbee network; the vehicular moving nodes collect the running information of a vehicle and transmit the running information to roadside fixed nodes in time;and the roadside fixed nodes quickly transmit the information to backward direction intersection fixed nodes and display the situation information of the running road sections of a bus on an intersection electronic display screen. The invention has good modularization, interference resistance, low cost, good real-time property, distributing type regulation and control and high positioning precision of the vehicle.

Description

technical field [0001] The invention relates to an intelligent transportation system and its monitoring and control method, belonging to the technical field of transportation system optimization and monitoring and control. Background technique [0002] At present, there are two main ways to obtain traffic information in intelligent transportation systems at home and abroad: one is to collect traffic flow monitoring equipment on the road, such as ring induction coils, radar, CCTV, etc. These equipment are expensive and require manual maintenance. Easy to wear, highly affected by weather and light conditions. The second is based on GPS / GSM traffic information collection system. That is, the vehicle-mounted GPS receiver receives and processes GPS information, and conducts two-way information exchange with the monitoring center through GSM / GPRS. However, there are still some problems in the use of GPS positioning technology in intelligent transportation. Since the transmission...

Problems solved by technology

The current Zigbee technology can solve this problem very well, although some people have proposed a solution for smart public transport, such as the article "Smart Public Transport System Based on Wireless Sensor Network" written by Song Song and Han Dong (Journal of Hefei University of Technology, 2008 January 2009), described the Zigbee-based intelligent public transport system, but did not give a specific implementation plan and verify the system; as of May 2009, there have been "Using Regionalization" proposed by Zhu Kaiyu, Liu Jiayu, etc. Device for wireless network transmission of bus information" (Chinese patent, application number 200720101730.6) and "Zigbee-based intelligent bus management system" (Chinese patent, application number 200820082900.5) proposed by Gao Zhongkang and Lin Qiangkai. These two inventions Creation both introduced Zigbee technology into the smart bus system, but neither of the two patents realized full-range monitoring and high-precision positioning during vehicle operation, nor did they propose a solution for how to implement a reasonable and effective Zigbee network layout for the entire city to meet no practical application requirements
