Graphical application system for multiple DSP (Digital Signal Processor) chips and application method thereof

Abstract

The invention relates to a graphical application system for multiple DSP (Digital Signal Processor) chips and an application method thereof. The application system comprises an upper computer, a communication management board and a main control board; the upper computer is connected with the communication management board by the Ethernet; the communication management board is connected with an FPGA (Field Programmable Gate Array) chip of the main control board by a backplane bus; and the FPGA chip of the main control board is connected with at least two DSP chips. The application method comprises the steps of: carrying out writing, compiling and management of graphical application on a PC (Personal Computer); downloading a compiled executable code into the DSP chips of an application target by a network communication protocol; and after powering on embedded application systems of the DSP chips again, loading the executable code of the graphical application so as to complete the graphical application of multiple DSP chips. According to the technical scheme provided by the invention, the difficult problem of large-scale programming is solved, control and protection on a power system are well designed, and the requirements of a high-voltage high-capacity flexible DC (Direct Current) system for controlling and protecting system software are met.

Description

technical field [0001] The invention relates to an application design of a power electronic control and protection system, in particular to a graphic application system for multiple DSP chips and an application method thereof. Background technique [0002] In the field of power system control and protection, the application of DSP is more and more extensive. With the implementation of UHV DC and flexible DC projects, the control functions become more and more complex, the configuration of protection is more and more, and the multi-DSP system appears more and more. With the increasing capacity of UHV and the scale of converter stations, higher requirements are put forward for control and protection functions and reliability. DSP software functions are becoming more and more complex. DSP The scale of the program is larger, and the development becomes difficult to grasp. The traditional code development mode programming is cumbersome, the register configuration is complicated,...

Problems solved by technology

Both of these methods require developers to spend a lot of time to master the correct settings of various registers inside the DSP and the programming methods of the software, and the development cycle is long.

Secondly, another problem encountered by DSP developers is to burn the code into Flash. They need to write the CMD file by themselves, and also need to write the Flash initialization program on the chip, which brings great difficulty to the developers.

For traditional programming languages, there are many codes, low code reuse rate, and large-scale program codes with hundreds of thousands of lines or more. It becomes more and more difficult to modify codes and program maintenance. Debugging is extremely troublesome. Subsequent program upgrades and There are great difficulties in optimization and system maintenance, and it is not suitable for the development and maintenance of large-scale power system control and protection products

At present, there is no graphical programming language for multi-DSP chip systems at home and abroad. For multi-DSP programming, it still relies on traditional code writing, and operates and debugs multiple DSP chips one by one.
