Orientation technology for fixing vehicle on running line

Abstract

The invention relates to a positioning technology used on the vehicle on a fixed line, in particular to a system and a method for performing public traffic vehicle positioning by using a wireless network. The system comprises a positioning device installed on the vehicle, a command system of a public traffic command center and an electronic station board on a platform. The invention has the advantages that the communication between one vehicle group is realized by using the positioning device and the wireless communication network, the position where the person is reported to the other party by using the stipulated code, and the position information from other vehicles is received, so that the relative positioning is realized; the position information of the vehicle also can be transmitted to the public traffic command center, the electronic station board on the platform and the mobile phones for the specific populations for reference; and the public traffic command center also can transmit the command to the specific bus. The invention provides the positioning information for the vehicles running on the fixed line in the typical application field, and especially provides the information for the positioning, the navigation and the management for the public vehicles. Furthermore, the invention also has the advantages of low cost and simple operation.

Description

technical field [0001] The invention relates to a positioning technology for vehicles on a fixed running line, in particular to a system and method for positioning public transport vehicles using a wireless network. Background technique [0002] "Public transportation priority" has been paid more and more attention by the transportation department in recent years, and the public transportation conditions have been greatly improved, but there is still a lot of room for development in improving the efficiency of public transportation. [0003] Existing buses usually all operate independently, and the driver cannot know the position of other vehicles on the same line, and cannot adjust the speed of the vehicle and keep a suitable relative distance with other vehicles. It often causes two adjacent buses to be too far apart or too close together, and even the situation that the vehicle behind surpasses the vehicle in front occurs. For the masses waiting for the bus at the platfo...

Problems solved by technology

However, the current mobile digital TV cannot provide positioning and navigation functions for bus drivers.

[0006] GPS positioning is the most important positioning and navigation technology at present. It can provide the absolute geographical location of the vehicle, but its disadvantages are high cost, inaccurate positioning, and inability to know the relative positions of other buses on the same line, so it is not suitable for public transportation applications.

Other positioning and navigation methods, such as using infrared to send positioning information or electronic label positioning, cannot be promoted due to various disadvantages such as cost
