Multifunctional wireless highway monitoring management system

Abstract

The invention relates to a wireless monitoring management system and especially relates to a multifunctional highway monitoring management system based on a wireless communication technology. A purpose of the invention is to provide a multifunctional wireless highway monitoring management system. The system comprises: an overload monitoring device, a vehicle device, a relay station, a zigbee wireless data transmission network and an information management center. Based on a zigbee technology, a GIS technology, a frequency modulation radio technology, an interphone technology and a sensor technology, positioning, navigation, whole course speed monitoring, speed information voice prompting, safe vehicle distance voice prompting and road section notice voice prompting can be performed to a running vehicle on a highway. And road condition information can be published to the vehicle on the highway. Under a special situation, scheduling information is published so as to schedule the vehicle and communicate directly with a driver. Bidirectional communication of the driver and a management department can be realized. The system can be used in a highway management system. Effective supervision can be realized and a highway accident rate can be reduced.

Description

technical field [0001] The invention relates to a wireless monitoring and management system, in particular to a multifunctional expressway monitoring and management system based on wireless communication technology. Background technique [0002] The real-time monitoring of vehicle positioning, speed measurement, violation judgment and traffic accident warning that can realize the whole section of the expressway is one of the key technologies to be solved urgently to ensure the safe driving of expressway vehicles. The existing highway management system can only realize one-way information communication, that is, obtain vehicle information through fixed-point video or speed radar and other equipment, and upload it to the highway management department, while the highway management department can only use fixed-position traffic lights or The signage provides brief driving information to the driver. This non-two-way information interaction not only seriously affects the timely a...

Problems solved by technology

The patent for this invention effectively controls the speed of the vehicle and facilitates the determination and punishment of speeding violations on the expressway. The disadvantage is that only video processing technology is used to obtain necessary information at the entrance and exit, and it cannot provide the whole process of vehicle speed monitoring information, which is only for safe driving. Provides post-processing means, does not provide drivers with any beneficial driving reference information in advance, and cannot play an early warning role in traffic accidents

The RFID-based expressway vehicle monitoring system has a relatively high degree of automation, but the laying cost of the optical communication network is high, maintenance is inconvenient, and it does not have the functions of full-process high-precision monitoring, system automatic threat judgment and alarm, and the speed calculation of all vehicles The monitoring computer is completed alone, and the monitoring computer has a large calculation pressure, which is difficult to meet the urgent requirements of the rapid development trend of my country's modern transportation
