Problems solved by technology

It clarified that real-time navigation is realized by using wireless network, server, vehicle-mounted software and its equipment, but this method only uses relevant information such as the position of the bicycle-mounted terminal, and does not take advantage of the characteristics of multi-user groups, such as mobile user groups on buses, At the same time, it only involves passive acquisition of information to achieve real-time navigation

Embodiment

[0047] The implementation block diagram of the vehicle positioning system and method for the terminal user to obtain the real-time operation map of the vehicle through the client device is as follows: Figure 5 As shown, a certain "user A" takes the G101 train from Beijing to Shanghai Hongqiao. Server 1 or 2 collects the location and other relevant information of various mobile user groups through active or passive means, and also includes the information on the running G101 train. The movement information of the mobile user group; the information processing device of the active or passive server processes the collected location information of each user to obtain the location parameter information of the vehicle where the multi-user group is located, including the mobile user group on the G101 train in operation (comprising "user A")'s motion information; the data transceiving device of the active or passive server distributes the position parameter information of the vehicle w...

Abstract

The invention relates to a multi-user group motion characteristic-based traffic tool positioning system and a method, which belong to the technical fields of signal processing and positioning. The positioning system comprises a server, a client device and a multi-user group with mobile communication equipment. The positioning method is divided into two modes, namely an active mode and a passive mode according to different server properties. By the system and the method, actual real-time position parameters of traffic tools in which multiple users are positioned are estimated by using group motion information of multiple mobile users, namely real-time position information of the multi-user group, and information such as real-time running route charts, arrival time and the like of the traffic tools is acquired, so that the system and the method are convenient for the users to travel and send and pick up other people at stations; the mobile users widely exist, so that the system and the method have extensive availability; special positioning equipment is not needed to be arranged on the traffic tools, so that the system and the method are easy to implement and are low in cost; and the users can conveniently and punctually acquire the real-time traffic running route charts of the traffic tools at any time, and the time cost is saved.

Description

technical field [0001] The present invention relates to a vehicle positioning system and method based on the motion characteristics of a multi-user group, in particular to a system and method for estimating parameters such as the position, speed, and direction of the vehicle where the user group is located based on the motion behavior of a multi-user group. The invention belongs to the technical field of signal processing and positioning. Background technique [0002] With the rapid development of transportation in various countries, the roads are getting longer and longer, there are more and more various means of transportation, and various types of traffic accidents are more frequent, traffic congestion, and delays of various means of transportation (trains, cars and planes), etc. Situations happen from time to time. According to expert research, after the use of intelligent transportation technology to improve the level of road management, the number of traffic accident ...
