Problems solved by technology

Due to the huge amount of simulation result data, it takes a long time delay for the embedded target machine 102 to transmit the simulation result to the host 101, causing the host 101 to fail to display the simulation result in real time

[0065] see Figure 5 , the flow chart of the first embodiment of a rapid control prototyping implementation method of the present invention. Include the following steps:

[0066] S501: Modeling, writing, and compiling real-time control programs and simulation programs. The real-time control program and simulation program needed for simulation are modeled according to the performance of the controlled object, and then the real-time control program is written and compiled under a specific operating system and software environment. The software environment for writing and compiling the real-time control program on the host computer of the present invention is preferably a Windows operating system and an Open Watcom C / C++1.5 compiler. OpenWatcom C / C++1.5 is a professional, superior performance, multi-platform C / C++ compiler with a set of powerful development and debugging tools, capable of developing pure DOS, extended DOS, WINDOWS95 / 98 / ME, 16-bit and 32-bit applications for WI...

Abstract

The invention provides a rapid prototype control system, comprising a host computer, a target machine and a control target; the target machine comprises a download unit, an acquisition unit, a simulation unit, a control unit and a display unit. The download unit is used to download the real-time control program and the simulation program from the host computer; the acquisition unit is used to collect the operating data of the control target; the simulation unit is used to operate the simulation program and simulate the operating data, and transfer the simulated result to the control unit and the display unit; the control unit is used to operate the real-time control program and switch the simulated result into a control signal, and then uses the control signal to control the operation of the control target; the display unit is used to display the simulated result. The invention displays the simulated result on the target machine and can make real-time observation of the simulation status through the simulated result displayed on the target machine so as to timely control the control target; the invention provides a low-cost rapid prototype control system.

Description

technical field [0001] The invention relates to the field of data simulation, in particular to a system and a method for realizing rapid control prototype. Background technique [0002] Rapid Control Prototyping (RCP, Rapid Control Prototyping) is derived from Rapid Prototyping (RP, Rapid Prototyping) in the manufacturing industry. In the initial stage of system development, quickly establish the control object and controller model, and conduct multiple offline and online tests on the entire system to verify the feasibility of the software and hardware solutions of the control system. This process is called RCP. The RCP technology is widely used in the research and development process of AC drive control system to improve the confidence of AC drive control system simulation. [0003] see figure 1 , is an existing rapid control prototyping system, including a host computer 101 , an embedded target computer 102 , and a controlled object 103 . The host computer 101 is equipp...
