0-1 dynamic data transmission and storage method and system based on reflective memory network

Abstract

The invention provides a 0-1 dynamic data transmission and storage method and system based on a reflective memory network. The 0-1 dynamic data transmission and storage method comprises the steps thatsimulation system members bind initial values; a simulation interface computer triggers real-time simulation interruption , counts in a 0-1 mode, and sends the interruption and a counting value to the simulation system member; the simulation system member calculates a VMIC data reading and writing address according to the count value in a preset simulation period, reads the data for resolving, and writes the data into an address corresponding to the VMIC; the data storage computer reads the data on the current address in real time according to the resolved VMIC data write-in address, and stores the data in the local space of the computer; and the simulation model computer completes the task in a preset simulation period and judges whether a preset simulation ending condition is met or not. Under the condition of ensuring the stability of the simulation system, the problem that the data volume of the simulation system is limited is effectively solved, and the expandability of the simulation system is improved.

Description

technical field [0001] The present invention relates to the technical field of real-time simulation control, in particular, to a 0-1 dynamic data transmission and storage method and system based on a reflective memory network, and more specifically, to a real-time data transmission of a guidance control hardware-in-the-loop simulation system The main role of the storage method is to provide enough data sharing space for each subsystem in the simulation system and to transmit and store efficiently and accurately. Background technique [0002] The current guidance control hardware-in-the-loop simulation real-time system mostly uses VMIC reflective memory for data transmission. The data storage space of the VMIC reflective memory card is 128M. The current communication protocol classifies the simulation data and uses the 128M data space of the reflective memory to open up multiple In the shared area, each simulation subsystem reads data from the reflective memory or writes data...

Problems solved by technology

However, with the development of missile technology, the range of missiles is getting longer and longer, and there are more and more simulation data. The simulation data of a ballistic trajectory is often hundreds of megabytes, and the disadvantages of the current transmission protocol are gradually revealed.

When the originally allocated data space is not enough to accommodate the simulation data of the long trajectory, various types of simulation data will overlap each other, affecting the data analysis after the test, and even affecting the test process

Therefore, under the framework of the existing communication protocol, the size of the onboard memory cannot meet the needs of long trajectory simulation

[0003] Aiming at this problem, a "0-1" dynamic data transmission and storage method based on VMIC is proposed. This technology is mainly used to improve the efficiency of the onboard memory of the VMIC reflective memory card and solve the problem of insufficient onboard memory in the existing data transmission mode. problem
