Abstract

The invention provides an excessive phase control method and vehicle equipment. The method includes allowing the vehicle equipment to acquire and record a current phase of the contact net pressure as a first phase according to phase-separating section entering signals sent by a central control device; allowing the vehicle equipment to acquire and record a current phase of the net pressure in real time as a second phase, and comparing with the first phase; if the second phase and the first phase are different, allowing the vehicle equipment to send phase-separating section exiting signals to the central control device. By the aid of the excessive phase control method and the vehicle equipment, loss of the phase-separating section exiting signals can be avoided effectively, and reliability of excessive phase control can be improved.

Description

technical field [0001] The invention relates to the field of over-phase control, in particular to an over-phase control method and vehicle-mounted equipment. Background technique [0002] At present, in order to reduce the impact of load imbalance on the national grid, the catenary phase needs to be changed at intervals. In order to avoid short circuits, it is necessary to establish a phase-separation zone between power supply sections of different network voltage phases. Correspondingly, when the train enters and leaves the phase-splitting area, it is necessary to send the corresponding signal entering the phase-splitting area and the signal exiting the phase-separating area to the central control device of the train, so that it can take corresponding processing, so as to realize the excessive phase separation of the train. control. [0003] In the existing over-phase separation control scheme, the signal entering the phase separation area and the signal exiting the phase...
