Problems solved by technology

While expressways bring benefits, they also bring a series of disadvantages and problems: (1) Difficulty in charging tolls
As the road network structure becomes more and more complex, the contradictions brought about by this split method become more and more prominent
(2) Fee evasion
However, this method needs to build an electronic sign station, and the reader needs to be replaced and upgraded later, and the system construction and maintenance costs are high
[0004] Aiming at problems such as toll evasion, speeding, and illegal parking on the expressway, the main method currently adopted is to install monitors, speed measuring radars and other devices at fixed points to monitor the driving conditions of the expressway. Although this monitoring method restricts the driver to a certain extent However, it is easily affected by external factors such as weather and light intensity, and it cannot really monitor the whole process, and it cannot fundamentally solve the illegal behavior of drivers.

Embodiment

[0028] figure 1 It is a principle diagram of an intelligent highway traffic monitoring system based on GPS and GPRS according to the present invention, including four parts: intelligent traffic equipment 1, charging equipment, data processing center 2, and background monitoring center 3. Among them, the intelligent traffic equipment can record the driving status of the vehicle in detail, send the information to the background monitoring center in real time, and can use the charging equipment to charge it, and maintain a long-term work after a single charge; the data processing center can monitor the vehicle. License plate recognition, which can write the specified information into the smart traffic device, can read and store the historical driving status from the smart traffic device, and can charge according to the historical driving track and mileage of the vehicle; the background monitoring center can receive and store information from the smart traffic Information such as ...

specific Embodiment

[0038] (1) When the vehicle enters the entrance of the expressway, the camera placed at the toll booth captures the license plate information of the vehicle. 2. The data processing center recognizes the license plate through the 201 license plate recognition module and saves it in the 203 information storage module. staff from Figure 4 Take out the fully charged 1 smart traffic device (the indicator light is red) from the charging device in the charging device. On the one hand, start the smart traffic device to make the 101GPS module start to work; The license plate number and the entrance location information are read out, and then written into the 102 information storage module through the 103 information reading and writing module;

[0039] (2) When the vehicle is driving on the expressway, the 101GPS module continuously collects the time information, position information, speed information, trajectory information, etc. of the driving vehicle, and saves them in the 102 inf...

Abstract

The invention discloses an intelligent expressway traffic monitoring system based on the GPS and GPRS. The intelligent expressway traffic monitoring system is characterized by comprising a background monitoring center, intelligent traffic equipment and data processing centers arranged on an inlet and an outlet of an expressway. The intelligent traffic equipment is allocated to vehicle users when vehicles enter the expressway, recycled when the vehicles exit the expressway and used for recording driving states of the vehicles and sends recorded vehicle information to the background monitoring center in real time; the data processing centers are used for recognizing vehicles when the vehicles enter the expressway and writing the recognized vehicle information in intelligent traffic equipment to be allocated; vehicle historical driving states are read according to recycled intelligent traffic equipment when the vehicles exit the expressway, and billing is carried out according to vehicle historical driving tracks or mileages; the background monitoring center judges states of the vehicles according to the vehicle information which is obtained in real time and sends warning messages or prompts according to the states of the vehicles. The system can precisely bill, relieve traffic jam, improve traveling efficiency, and meanwhile guarantee orderliness and smoothness of the expressway.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, in particular to an intelligent monitoring system for expressway traffic based on GPS and GPRS. Background technique [0002] In recent years, the rapid development of expressways has brought great convenience to people's travel, and at the same time boosted the rapid development of regional economy. While the expressway brings benefits, it also brings a series of disadvantages and problems: (1) The difficulty of toll collection. With the continuous expansion of the road network structure, there have been multiple loops and paths between rings, and there are multiple paths between two points with the same starting and ending points, which makes the toll collection and demolition of each path and road investor into problems. At present, toll charges are mainly based on the shortest path method, that is, whether to participate in splitting is determined according to the distanc...
