Problems solved by technology

However, since the field of application modeling and simulation of this model method is still in its infancy, most of the existing behavior tree simulation tools can only simulate and verify simple demand models, and cannot complete synchronization, state , real-time and probability characteristics and other problem description and analysis, there is still a lack of distributed system behavior simulation analysis tools based on behavior trees, so it is of great significance to study a method for guiding the realization of such tools

Embodiment 1

[0058] Embodiment 1, main body implementation steps of the present invention.

[0059] The basic idea of ​​the method described in the present invention is to firstly provide a behavior tree graphical editor, which is used to establish the model of the device and the system using a graphical method; the system model is converted into an XML document, and the document contains all nodes in the model and their interrelationships; search and simulate the XML document, select the execution path according to the control logic of the behavior tree, and assume that the searched process is the execution process of the behavior during the execution process, and record the results after execution. When it is necessary to analyze the reachability, real-time and reliability of the model, it is necessary to use a fixed search strategy (depth-first or breadth-first algorithm) to verify whether each node in the model is reachable, and output the corresponding verification As a result, aids...

Embodiment 2

[0081] Embodiment 2, detailed implementation steps of the present invention.

[0082] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0083] The object of the present invention is to provide a method for realizing a distributed system behavior simulation analysis tool based on a behavior tree, so as to solve the problem of realizing the simulation verification tool based on a behavior tree model. What the model simulation tool needs to provide is a graphical modeling interface. First, the basic primitives of the behavior tree need to be given, such as figure 1 As shown, in addition, it is necessary to give the usage of various graphics elements and their interrelationships by way of explanation. On the basis of the given graphic elements, the user can build a behavior tree model of the system according to the actual system. The example model is as follows figure 2 shown. The simulation ...
