Problems solved by technology

[0006] The present invention is aimed at the problems in the prior art, and provides an auxiliary positioning system and method for an urban rail transit train in a faulty environment, which overcomes the problem that the safety of the train is greatly impacted if a signal fault occurs in the prior art. The problem is that by using RFID technology for multiple positioning of vehicles in the driving range and using infrared sensing technology for parking positioning equipment layout methods, the impact and loss caused by signal system failures can be reduced, and the actual needs of rail transit companies for positioning equipment layout can be met.

Embodiment 1

[0032] Auxiliary positioning system for urban rail transit trains under fault conditions, including:

[0033] RFID information label module, described information label module has three, is respectively positioned at the locomotive of train, in the car and tailstock, is used for storing train information data, and the train information data stored by RFID information label module at least includes train car body number, train body Length and train position information, the train position information refers to the information label module is located in the front of the train or in the car or the rear of the train;

[0034] There are at least three RFID readers, two of which are respectively located at the two ends of the parking platform to read the information in the RFID information label module, and the rest are located in the train running section, according to the distance between the running section and the length of the train body set up;

[0035] Infrared emitters, the...

Embodiment 2

[0049] An auxiliary positioning method for urban rail transit trains in a fault environment, comprising

[0050] Step1. Store the basic information of the train into the RFID tag

[0051] The basic information of the urban rail transit train to be run is stored in the RFID tag in the form of data.

[0052] The information of the urban rail transit train stored in the RFID tag includes: the car body number of the train, the body length of the train, and the position information of the tag fixed on the corresponding train. Among them, the position information of the train where the tag is located includes: the front, the middle, and the rear. These three positions are stored in the RFID tag in the form of CT, CZ, and CW letters respectively.

[0053] Step2, install RFID tags and RFID readers

[0054] 1) Install RFID tags:

Abstract

The invention discloses an auxiliary positioning system of urban rail transit train under a fault environment, including an RFID information tag module, an RFID reader, an infrared emitter and an infrared sensor. By using RFID technology, the vehicles in the traveling section are located, which not only can the position information, the traveling speed and the traveling direction of the train be detected when the train is traveling, but also the traveling acceleration of the train can be deduced after the train passes through, and the dynamic running state of the train can be judged more accurately, thus ensuring the safety of the line transportation and realizing the safety interval control of the train. At that same time, the infrared induction technology and the RFID technology are adopt to jointly complete the parking position operation. Under the condition of signal system failure, the train can transmit the information to the staff in time, reduce the influence and loss caused bysignal system failure, make the train stop and enter the station more accurately, and meet the actual requirements of the rail transit enterprises for positioning equipment layout.

Description

[0001] Field [0002] The invention belongs to the intelligent technology of urban rail transit, and in particular relates to an auxiliary positioning system and method for urban rail transit trains in a fault environment. Background technique [0003] In urban rail transit, the operation of trains mainly depends on the signal system. It is an important system to ensure the safety of line transportation, improve transportation efficiency and improve labor conditions. It can realize the functions of train safety interval control, precise positioning and fixed-point parking. However, the signaling system is an electromechanical system, and failures are inevitable. When the automatic train protection (ATP) operation mode needs to be cut off when the signal equipment or system fails, the train operation is completely dependent on manual operation and management, which greatly reduces the transportation efficiency of the line and increases the risk of accidents. [0004] In recent...
