Embodiment Construction

[0009] The present invention will be further described below via accompanying drawing:

[0010] as attached figure 1 As shown, the digital quantity control method of the power electronic distributed control system firstly sets the digital quantity storage buffer pool 1 of the power electronic control system, and the digital quantity storage buffer pool 1 of the power electronic control system is additionally equipped with a distributed control system connector 2. The distributed control system connector 2 is externally connected to the pin 3 , and the connection pin 3 of the distributed control system connector 2 triggers conduction with the driver 5 of the power supply device 4 of the digital quantity storage buffer pool 1 of the power electronic control system. The said distributed control system connector 2 is provided with a communication compatible conversion module inside. When the power electronic distributed control system is running, a large number of data streams mu...

Abstract

Disclosed is a digital quantity control method of a power electronic distributed control system. During the process of the operation of the power electronic distributed control system, before a large number of data flow is sent simultaneously to the power electronic distributed control system to be processed, the large number of data flow is prestored in a digital quantity storage buffer pool of the power electronic distributed control system, and the digital quantity storage buffer pool of the power electronic distributed control system is communicated with a connector of the power electronic distributed control system in breakover mode. The large number data flow is classified and taken out and processed. A strong function of the power electronic distributed system and a situation of not losing data under the communication environment of large digital quantity are achieved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a digital quantity control method of a power electronics distributed control system. Background technique [0002] Power electronics distributed control system is commonly used in current power electronics control. The power electronics distributed control system is composed of process control level and process monitoring level. It is a multi-level computer system with communication network as the link. The basic idea of ​​4C technology is decentralized control, centralized operation, hierarchical management, flexible configuration and convenient configuration. [0003] However, such a power electronic distributed control system is not powerful in a communication environment with a large number of numbers, and often loses data. Contents of the invention [0004] The invention provides a digital quantity control method of a power electronic distributed control system....
