All falling within the scope of the present invention.
This example takes a certain semi-physical simulation interconnected system as an example.
As in FIG. 1, the agent software and adapter are deployed in two processes. The process of the agent software completes the ordering/publishing of the data through the DDS. The adapter software is embedded in a control program of the guidance semi-physical simulation system in a thread form, the original control program of the guidance semi-physical simulation system is used as a main thread, the adapter thread is used as a sub-thread, and the two threads cooperate to complete the control of the semi-physical simulation system. The simulation agent software and the adapter software realize communication and data interaction functions through a shared memory. The adapter thread and the main thread are in the same process and interact with the global variable through messages, wherein the simulation command is transmitted to the main thread through the messages, and the state of the simulation system is acquired from the main thread through the global variable; the adapter completes the read-write of the simulation data by reflecting the memory I/O operation.
As shown in fig. 2, the agent software monitors the DDS data stream through the Listener, and when receiving the DDS data, triggers the related message to convert the DDS data into the simulation command and data, and writes the simulation command and data into the shared memory. As shown in fig. 3, a timer is set in the agent software to periodically listen for the activity of the adapter operating the shared memory. As shown in fig. 4, when the agent software monitors the data written into the shared memory by the adapter software, the data is converted into DDS data and sent to other systems.
As shown in fig. 5, a timer built in the adapter periodically monitors the operation activity of the simulation agent on the shared memory, and simultaneously monitors the state and data of the semi-physical simulation system, and simultaneously determines whether the conditions for uploading real-time data are satisfied. When the timer monitors relevant signals (flag bits of data ready, data changed, command ready, state ready, and the like), corresponding messages are sent, and corresponding functions are mapped to complete uploading and downloading of data. As shown in fig. 6, when downloading emulation data, the adapter reads data from the shared memory, performs message conversion, and then writes the data into the reflective memory; and when the command is downloaded, the adapter sends the simulation command to the semi-physical simulation main control program in a message form. As shown in fig. 7, when uploading simulation data and commands, the adapter collects the semi-physical simulation status and data information in real time and transmits the status and data information to the agent software through the shared memory.
As shown in fig. 8, each system drives each system simulation engine by using a homologous, high-precision timing signal output by an external GPS time system server, so that time synchronization of each system can be directly guaranteed.
