Embodiment 1

[0026] In the embodiment of the present invention, the rail transit vehicle includes two high-voltage units, and each high-voltage unit is equipped with two pantographs. When the two pantographs are running normally, only one pantograph is raised, and the other is used as a backup .

[0027] Based on the above technical background, in order to keep the wear states of the two pantograph slides consistent, it is necessary to intelligently control the wear of the two pantograph slides.

[0028] According to an embodiment of the present invention, an embodiment of an intelligent control system for pantograph slide wear is provided, refer to figure 1 ,include:

[0029] Speed ​​sensor, each head car of the track running vehicle is equipped with a speed sensor, which is used to collect the speed information of the vehicle running and send it to the main controller;

[0030] The main controller is connected to the speed sensor through the communication bus, receives the vehicle runn...

Embodiment 2

[0035] According to an embodiment of the present invention, an embodiment of an intelligent control method for pantograph slide wear is provided, refer to figure 2 , including the following steps:

[0036] Step S101, based on the running speed of the vehicle, determine the running distance of each pantograph in the high voltage unit of the vehicle;

[0037] Based on the calculation relationship between speed and distance, the cumulative running distance of each pantograph is calculated. The calculation process is simple and easy, and there is no need to consider complex judgment processes such as temperature and pressure, which facilitates the implementation of the patented technical solution.

[0038] Step S102, judging whether the pantograph selection condition is satisfied, if so, proceed to step S103, otherwise, maintain the last state of raising the bow;

[0039] Specifically, the pantograph selection condition is specifically: the vehicle is in a stationary state, and ...

Embodiment 3

[0042] According to an embodiment of the present invention, a rail vehicle is provided, including: the pantograph sliding plate wear intelligent control system disclosed in Embodiment 1 realizes the pantograph lift control of the vehicle; or, adopts the pantograph disclosed in Embodiment 2 The intelligent control method of the wear of the bow skateboard realizes the bow control of the vehicle pantograph.

Abstract

The invention discloses a pantograph pan abrasion intelligent control system and method. The system comprises a speed sensor which is configured to collect the running speed information of a vehicle,and transmit the running speed information to a main controller, a main controller which is configured to calculate the running distance of each pantograph in a vehicle high-voltage unit according tothe received vehicle running speed information, and determine a pantograph which needs to be lifted, and output a pantograph selection signal to a remote output unit, a remote output unit which is configured to send a switching instruction to a switching unit according to the received pantograph selection signal, and the switching unit which is configured to switch a pantograph lifting instructionto the pantograph needing pantograph lifting according to the received switching instruction. According to the pantograph pan abrasion intelligent control system and method of the invention, the intelligent control of the abrasion degree of pantograph pans can be realized, the abrasion degree of the two pantograph pans in the vehicle high-voltage unit is ensured to be consistent, and the overhauland maintenance workload of the vehicle pantograph is reduced.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to an intelligent control system and method for pantograph sliding plate abrasion. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The pantograph slide plate is the part where the pantograph is in contact with the power grid. At present, the common slide plates on the market are usually made of graphite and other metal alloys. Because the pantograph slide plate has a fast moving speed (generally up to 350km / h) , so the wear of graphite is relatively severe. When the pantograph slide wears to a certain extent, it is easy to cause situations such as pulling the net or jamming the net and temporary power failure, which may cause major railway safety accidents; Bow slides require regular servicing. [0004] Rail transit vehicles usually i...
