In one embodiment, as shown in fig. 1, the invention discloses a multi-simulation scene dynamic management method, which comprises the following steps:
step one, the simulation scene management software receives a scene starting instruction of the guiding control software;
step two, the simulation scene management software sends a starting instruction to proxy software on the corresponding computer;
step three, the proxy software starts a simulation scene instance on the local machine;
step four, the simulation scene management software receives a scene intervention instruction of the guiding control software;
step five, the simulation scene management software sends scene intervention instructions to simulation scene instances on the corresponding computers;
step six, executing a scene intervention instruction by the simulation scene instance;

step eight, the simulation scene management software receives a scene closing instruction of the guide control software;
step nine, the simulation scene management software sends a closing instruction to agent software on a corresponding computer;
and step ten, the proxy software closes the simulation scene instance on the local machine.
The simulation scene management software needs to be started along with the computer operating system, presets the IP addresses of computers to be operated by different scene examples, and sends instructions to the proxy software through network communication.
The proxy software is started along with the operating system, and can start or close the simulation scene instance program on the computer through an application program interface provided by the operating system of the computer.
The simulation scene instance needs to be able to send the current simulation time, the CPU utilization rate of the host computer and the memory utilization rate of the computer to the simulation management software, and the simulation scene instance software can receive the scene intervention instruction through the network communication method.
The scene intervention instructions can cause a change in the state of the simulation object in the simulation scene.
Specifically, step one, the simulation scene management software receives a scene starting instruction of the guiding control software, and needs to be ensured to be in an operating state first, deployed on a remote server and kept in a normally open state along with a computer. The simulation management software can obtain the IP addresses of the computers on which the simulation scene programs are deployed currently in a mode of reading the configuration files, and can cope with the situation that the number of the computers on which the simulation scene programs are deployed is increased or the IP addresses are changed by adopting the mode of the configuration files. The simulation management software should be able to intuitively display the running states of different simulation scene instances, and the adopted data structure should support the situation that the number of simulation scene instances is expanded.
Specifically, in the second step, the simulation scene management software sends a starting instruction to proxy software on the corresponding computer. The proxy software itself needs to keep a normally open state, and because the proxy software receives the start and close instructions through network communication, in order to avoid receiving illegal start and close instructions, the proxy software can set a receivable instruction source range through a configuration file, and unnecessary IP addresses are eliminated.
In step ten, when the proxy software starts the simulation scene instances on the local machine, each started simulation scene instance needs to be identified, for example, by using attributes such as a process PID provided by the operating system, when the simulation scene instance is closed, a certain simulation scene instance can be closed in a targeted manner.
