Embodiment 1

[0033] Over-phase area control system for dual-stream vehicles, such as figure 1 Shown: including the receiving module located on the vehicle, the processing module located on the vehicle, the positioning module located on the vehicle, the prompt module located on the vehicle, the enabling beacon module preset on the entry side of the phase separation area and the preset The operation beacon module set at the boundary of the phase separation area, one enable beacon module is set, and the enable beacon module sends an enabling signal for the vehicle to perform pre-load reduction. Pre-load reduction refers to making the traction system on the vehicle enter inertia For load shedding, one operation beacon module is set, and the operation beacon module sends the landmark signal for reloading the vehicle; the receiving module receives the landmark signal of the operation beacon module and sends it to the processing module, and the receiving module can use the existing signal Beacon ...

Embodiment 2

[0043] The difference from Embodiment 1 is that the dual-stream vehicle’s over-phase-separation zone control system also includes a mileage module and a timing module on the vehicle. The second mileage after loading, the mileage module can be obtained directly from the vehicle control system. When it is judged that it is about to enter the phase separation zone, the processing module judges the enabling theoretical position of the enable signal according to the first mileage value, for example, according to The preset enabling signal sending point determines the enabling theoretical position, and judges whether the vehicle has reached the enabling theoretical position according to the real-time position. When the enabling theoretical position is reached, the processing module sends a timing signal to the timing module, and the timing module starts the preset Set the timing of the duration. When the timing is over, the processing module will send a pre-load shedding switching co...

Abstract

The invention relates to the technical field of electric traction outside vehicles, in particular to a system and a method for controlling a passing neutral section area of a double-current system vehicle, the system comprises a receiving module, a processing module, an operation beacon module, a positioning module, a prompt module and an enabling beacon module, and the method comprises the steps that S1, whether the vehicle is about to enter a neutral section is judged according to the real-time position of the vehicle, if yes, continuous neutral section passing prompt information is sent for neutral section passing prompt; S2, an enable signal for pre-deloading the vehicle is received, and a pre-deloading switching instruction is sent according to the enable signal; and S3, when the landmark signal is received, a neutral section passing operation control instruction is sent, and neutral section passing prompt is stopped after the neutral section passing operation control instruction is sent. According to the method, prompting can be carried out in advance and all the time, and over-phase control operation lag caused by negligence is avoided.

Description

technical field [0001] The invention relates to the technical field of electric traction for the exterior of vehicles, in particular to a system and method for controlling over-phase-splitting regions of dual-stream vehicles. Background technique [0002] Dual-current vehicles refer to trains that are compatible with catenary power supplies of two different voltages. For example, catenary power supplies of DC 1000V-1800V and AC 17.5kV-31kV are respectively used for power supply during train operation. A phase separation area needs to be set at the junction of the AC section and the DC section to isolate the AC section and the DC section. The phase-splitting area is set in the AC section, and the phases of the alternating current on both sides of the phase-splitting area are different. At present, the control method of the vehicle over-phase division is to set the power-off point to start the power-off operation and set the power-on point to start the power-on operation. Whe...
