Method and system for charging multiple guns in turn

Abstract

The invention provides a method and a system for charging with multiple guns in turn in one pile. The method includes the following steps: a plurality of processors in one-to-one corresponding to a plurality of charging guns are set, the plurality of processors and a plurality of charging modules are connected to a same bus, one of the processors is set as a primary processor, and other processors are set as secondary processors; the primary processor collects the statuses of the charging guns which are reported by the processors in a real-time manner via the bus, and sets the priority levels of the processors via the bus based on a priority level distribution rule when the statuses of the charging guns change or a queue number reissued by a backstage is received; and the processor with the highest priority level obtains charging management authority, and processes the communication with all charging modules. As one processor only control one gun, so as to reduce the system complexity; increase or decrease of processors on the bus is convenient, and flexible expansion is realized; the manner of one primary gun and multiple secondary guns is adopted, the failure of one secondary gun does not affect the charging of other guns, and if the primary gun is failed, one of the secondary guns can be set as the primary gun to continue charging, so as to improve the fault freedom.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a charging method for multiple guns in one pile in turn. Background technique [0002] The current multi-gun wheel charging system basically adopts a single processor solution. One processor manages multiple charging interfaces. The processor collects the status of multiple interfaces in real time. For sorting, all work is processed in one processor, and the system is complex. Due to the limitation of processor resources, the number of charging ports is limited, and the expansion performance is poor. As long as the processor fails, all charging cables cannot be used, and the fault tolerance is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method and system for charging multiple guns in turn in view of the above-mentioned defects of the prior art. [0004] The technical solution adopted by the prese...
