Problems solved by technology

Although the location of the tram can be guaranteed through strict procedures, there are always potential safety hazards in human confirmation. Any negligence will cause wrong display of the tram, which will directly affect the safety and reliability of the operating system
The confirmation of the running direction of the tram can be solved by the current technology, but the calculation cycle is long, and it needs to run for a certain distance before it can be accurately confirmed. The convergence speed of the algorithm is poor, and there are misjudgments

Embodiment Construction

[0028]The technical solution of the present invention will be further described in non-limiting detail below in conjunction with preferred embodiments and the accompanying drawings.

[0029]The modern tram operation control system has a line control boundary, and all trams are put into main line operation from here. The operation control system performs the initial setting of the tram after the tram enters the range from the system boundary.

[0030]Such asfigure 1 As shown, an initial positioning method of a modern tram initial positioning system. The initial positioning system includes a number of sensor devices set beside the track, a receiving antenna set on the tram, the front activation terminal and the on-board host, which are set in the background The tram positioning server. The sensor device is used to store and determine the unique fixed ID of the device and other auxiliary information. The antenna is mainly responsible for establishing a wireless channel with trackside sensing...

Abstract

The invention discloses an initial positioning system for a tram, the initial positioning system includes an on-board host on the tram and a tram positioning server in the background, the initial positioning system for the tram also includes sensors arranged on the tram track equipment, a receiving antenna for receiving information of the sensor device, and an activation terminal, the receiving antenna includes a first receiving antenna (1) and a second receiving antenna (2) respectively arranged at both ends of the tram head, and the activation terminal includes The first activating end (7) and the second activating end (8) respectively arranged at the two ends of the trolley car, the present invention effectively improves the positioning accuracy of modern trams during initialization, and at the same time through reasonable arrangement of trackside equipment, it can Quickly determine the initial running direction of the tram.

Description

Technical field[0001]The invention relates to the field of rail transit, and in particular to an initial positioning method of a modern tram initial positioning system.Background technique[0002]The operation control system of modern trams is the core system of trams, which is related to the safe operation of trams. At present, trams mainly rely on GPS for tram positioning. Due to poor GPS positioning accuracy and high-rise building obstruction, the tram cannot accurately locate the track where the tram is located and the initial running direction of the tram during initialization. At present, when the tram is initialized, it is mainly by manually confirming the track where the tram is located, and accurately positioning the track by setting the system. The confirmation of the running direction of the tram is mainly judged by the running distance of the tram, and the running direction of the tram is judged based on the location of the tram for a period of time.[0003]At present, the m...
