The pulse power supply real-time control system of the present invention has the advantages of capacity of improving transmission real-time performance, transmission delay determinacy and reliability of data and commands in the control system, etc.

Description

technical field [0001] The invention mainly relates to the field of high-power pulse power supply, in particular to a pulse power real-time control system based on a reflective memory network and a DSP controller. Background technique [0002] With the continuous development of research in the field of controlled nuclear fusion and the increasing application of test equipment in the military field, the demand for high-power pulse power supplies is also increasing; at the same time, higher requirements are also put forward for the performance of high-power pulse power supplies. For example: the requirements for real-time response speed, control accuracy, reliability and stability of the power supply are getting higher and higher. [0003] As one of the core components of the high-power pulse power supply, the real-time performance of the control network and controller directly determines the real-time performance of the high-power pulse power supply device. Most of the tradi...

Problems solved by technology

[0004] In the above mode, the data interaction between the master control unit and each sub-control unit is realized by means of bus communication, the period of bus communication is long, and the real-time index is not high enough; The real-time control performance of this control system will be further reduced; in terms of real-time data interaction performance, data transmission rate, bandwidth, etc., the traditional pulse power control network is far inferior to the performance of the reflective memory network
