According to the data real-time transmission and storage method of the guidance control semi-physical simulation system, the guidance control semi-physical simulation system realizes the steps of the method.

The following examples illustrate the invention in further detail:

the embodiment is described with reference to fig. 3, and the embodiment is a specific implementation process of the VMIC-based "0-1" dynamic data transmission and storage method specifically described:

referring to fig. 3, the core of the implementation of the VMIC-based "0-1" dynamic data transmission and storage method is to reuse the VMIC reflective memory space through a "0-1" mode triggering mechanism, and dynamically switch the VMIC reflective memory address in real time. The data interaction and storage process is as follows:

the simulation system member reads a count value m in real time through a VMIC reflective memory, wherein the count value m is obtained through (k mod 2), and the (k mod 2) represents a remainder obtained by dividing k by 2; m is the dynamic switching back and forth between 0 and 1, the corresponding reflective memory address can also be dynamically switched back and forth, and k represents the kth simulation cycle;

the simulation system member combines the real-time reading count value m through a simulation communication protocol formulated by a simulation system designer to calculate the corresponding VMIC reflection memory data reading and writing address in real time, and the specific numerical formula of the address is as follows:

write address a + n × m + l (1)

Wherein a represents a base address specified by the emulated communication protocol; n denotes the total length of data of one simulation cycle, m is 0 or 1, l denotes an address offset, and l is {0,1, 2.

The simulation system member obtains real-time input data from the resolved VMIC reflective memory data reading address, correspondingly processes the data, completes the work of the simulation system member, and outputs the processed data to the resolved VMIC reflective memory data writing address;

the data storage computer writes the address according to the calculated VMIC reflection memory data, reads the data on the address in real time, and stores the data in the local space of the computer;

a VMIC-based 0-1 dynamic data transmission and storage method repeatedly utilizes a VMIC reflection memory space, and data of a k +2 simulation period can cover data of a k simulation period, so that a data storage computer is required to read and store the data in real time before the data of the k simulation period is covered.

Part members of the simulation system can read data written by other simulation system members through the VMIC reflective memory, and in order to prevent read-write conflict of the same VMIC reflective memory address, the specified data reads data from the address corresponding to the count value (1-m), and writes data in the address corresponding to the count value m.

A VMIC-based 0-1 dynamic data transmission and storage method relates to the technical field of real-time simulation control and solves the problem of limitation of data transmission and storage caused by limited reflective memory space of a VMIC in the existing real-time simulation system. The real-time simulation system triggers a simulation time sequence through an accurate clock of an RTX real-time operating system of the simulation interface computer, generates a count value in real time, and sends the count value to members in the simulation system in real time through a VMIC reflective memory network, and the members in the simulation system calculate data reading and storage addresses according to the real-time count value. The original simulation method adopts a sequential accumulation mode of counting values, makes full use of VMIC reflective memory space, can read data from a fixed data address and store the data after simulation is finished, is limited by the VMIC reflective memory space, and cannot normally operate a simulation system if the simulation data volume exceeds the reflective memory space. A count value of a 0-1 dynamic data transmission and storage method based on the VMIC adopts a 0-1 circulation mode, a VMIC reflection memory space is reasonably utilized, and dynamic addresses are adopted to transmit and store data in real time in a simulation process.
