Problems solved by technology

[0007] When the dual-current vehicle is working under different power grids, it is necessary to switch the AC and DC circuits. If the switch is wrong, it will cause the risk of the high-voltage circuit of the vehicle under different power grids.
Rush forward means that when the DC high voltage enters the AC high voltage circuit or the AC high voltage penetrates into the DC high voltage circuit, this situation may cause great damage to the high voltage components of the vehicle or the vehicle

Embodiment

[0070] A dual-stream rail transit vehicle control system, basically as attached figure 1 Shown: includes:

[0071] Information acquisition module: used to obtain the AC-DC switching instruction when the rail vehicle arrives at the switching area of ​​the DC power supply area or the AC power supply area; the switching area includes initial beacon points, control bit beacon points and completion bit beacon points, and the AC The DC switching instruction includes an initial position sub-instruction corresponding to the initial beacon point, a control bit sub-instruction corresponding to the control bit beacon point, and a completion position sub-instruction corresponding to the completion bit beacon point; figure 2 , image 3 As shown, in this embodiment, the switching area is the area between the ground beacon 1 and the ground beacon 5, and in this solution, the AC / DC switching command is specifically obtained at the position of the ground beacon 1. About ground beacons. As ...

Embodiment 2

[0114] The difference between the second embodiment and the first embodiment is that the system further includes the following modules:

[0115] Fault collection and storage module: used to collect, organize and store the fault information of rail vehicles during travel. The fault information includes a regular fault table and a switching fault table. Both the conventional fault table and the switching fault table include fault names and fault causes , troubleshooting measures and fault levels.

[0116] Fault protection module: used to perform fault protection according to the fault information stored in the fault collection and storage module when a fault occurs in the AC-DC switching of the rail vehicle is detected.

[0117] Fault partial removal module: used to disconnect and remove all or part of the rail vehicle corresponding to the abnormal fault from the power supply circuit when an abnormal fault is detected on the rail vehicle, and use a sound unit train group to pull...

Abstract

The invention relates to the technical field of rail transit control, in particular to a double-current system rail transit vehicle control system and method, the method is applied to the system, and the system comprises an information acquisition module which is used for acquiring an alternating current and direct current switching instruction when a rail vehicle reaches a switching area of a direct current power supply area or an alternating current power supply area; a direct current working condition control module which is used for generating first initial prompt information; the direct current working condition control module is also used for cutting off a direct-current power supply loop of the railway vehicle according to the control position instruction; and is also used for connected with the alternating current supplying loop of the rail transit; an alternating current working condition control module which is used for generating second initial prompt information; and the alternating current working condition control module is used for switching off the AC power supply loop of the railway vehicle according to the control position sub-instruction; and is used for connecting with a direct-current power supply loop of the railway vehicle. According to the double-current system rail transit vehicle control system, accurate AC / DC loop switching can be carried out on the double-current system vehicle, and the risk that the double-current system vehicle tends to enter a high-voltage loop under different power grids, so that high-voltage devices of the vehicle or the vehicle are greatly damaged is avoided.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to a dual-stream rail traffic vehicle control system and method. Background technique [0002] Traction power supply system refers to the current system, voltage level and power supply mode adopted by the power supply system to supply power to electric vehicles or electric locomotives. It is widely regarded as an advanced traction power supply system, and has formed a national standard. Mainly for single-phase power frequency 25kV AC system and DC traction power supply system. [0003] The single-phase power frequency 25kV AC system is generally suitable for mainline electrified railways with large transport volume, heavy load, high speed and long transport distance, such as common-speed passenger-freight common-line railways, 200-250km / h passenger-freight common-line railways or passenger dedicated lines , 300km / h and above high-speed railway or passenger dedicated l...
