Control power supply for subway safety door system

Abstract

The invention relates to a control power supply for a subway safety door system, which comprises a parallel operation module, and a first power supply control module and a second power supply control module which are connected between the parallel operation module and an input power supply and are connected to a subway safety door through a first unidirectional conducting device and a second unidirectional conducting device in the parallel operation module respectively, wherein the first power supply control module and the first unidirectional conducting device form a first power supply; the second power supply control module and the second unidirectional conducting device form a second power supply; and the first power supply and the second power supply work in a master-master mode for supplying power to the subway safety door together or a master-slave mode for supplying power to the subway safety door through one power supply. When the conventional control power supply for the subway safety door fails, the safety door cannot be opened automatically or manually so as to cause large negative effect. By implementing the control power supply, when one power supply is damaged, the normal use of the other power supply cannot be affected, so the power supply reliability of the system is improved; and the control power supply has the advantages of low equipment invest, short development period and no need of adjustment.

Description

technical field [0001] The invention relates to a subway safety door, in particular to a reliable control power supply for a subway safety door. Background technique [0002] During the operation of the conventional subway safety door (or screen door) system, the control power supply needs to send various signals and door opening and closing commands to the safety door through the PSC cabinet. When the control power supply stops running due to failure, the entire safety door system will also stop running. . Due to the failure of the control power supply (that is, DC110V), the screen door cannot be opened automatically and manually, which will cause a relatively large negative impact. Therefore, how to minimize the impact of power failure is an important issue. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control power supply for the subway safety door system in view of the above-mentioned defects in the pr...
