Embodiment Construction
[0048] For reference and clarity, technical terms, abbreviations or abbreviations used hereinafter are summarized as follows:
[0049] DSP: Digital signal processor, a unique microprocessor, is a device that processes large amounts of information with digital signals. Not only is it programmable, but its real-time running speed can reach tens of millions of complex instruction programs per second, far exceeding that of general-purpose microprocessors. It is an increasingly important computer chip in the digital electronic world.
[0050] HXD3C: The current mainstream AC drive six-axle trunk line passenger and freight dual-purpose electric locomotive.
[0051] ARM: It is a RISC processor with high performance, low cost and low energy consumption. At present, it has been applied in various products such as industrial control, consumer electronics products, communication systems, network systems, and wireless systems.
[0052]FPGA: Feld-programmable gate array, Field Programmabl...

The embodiment of the invention discloses a power supply control method, device and system for an HXD3C type electric locomotive train. The power supply control device for the HXD3C type electric locomotive train comprises two sets of same power supply control subsystems, one set of power supply control subsystem is electrified for carrying out control on a power supply system of the HXD3C type electric locomotive train, and the two subsystems are connected through a conversion control unit; each power supply control subsystem comprises a power supply control unit, a pulse allocation unit and a digital input and output (IO) unit which are inserted by using a back plate and communicated with a bust; and the power supply control units, the pulse allocation units and the digital IO units of the power supply control subsystems are inserted by the back plate and communicated with the bus, digital quantity acquisition and processing are realized, and integration degree of the device is improved. Due to the layout of an insertion line, input and output ports of all parts are installed without being singly installed by depending on manual works, thus the technical effect of improving power supply control reliability is achieved.
Description
technical field [0001] The present invention relates to the technical field of train power supply control, and more specifically relates to a train power supply control method, device and system for an HXD3C electric locomotive. Background technique [0002] The electric locomotive train power supply system is a system in which the electric locomotive itself provides the electric energy required for train air conditioning, heaters and lighting. The power supply system needs to be centrally controlled by the power supply control system to achieve reliable power supply. [0003] The existing HXD3C electric locomotive train power supply control system consists of two identical train power supply cabinets, and each train power supply cabinet contains an independent train power supply control device, such as figure 1 As shown, the existing train power supply control device includes the connection lines between the power supply control board and the conversion control board, etc.,...
