Self-adaptive unmanned trolley simulation method based on Datalog rule

Abstract

The invention discloses a self-adaptive unmanned vehicle simulation method based on a Datalog rule, and the method comprises the steps: building a dynamically changing self-adaptive unmanned vehicle simulation scene, improving an operation scene through employing a digital matrix and the Datalog rule, and achieving the dynamic updating of the scene; and constructing a state conversion diagram of the operation logic according to the state of the unmanned vehicle and the change of the environmental parameters, performing equivalent translation on the operation logic by using a Datalog rule, and reasoning the state conversion process to realize the operation logic of the self-adaptive unmanned vehicle. According to the method, the dynamic change of the environment and the update of the operation logic are stripped and extracted from the system codes, the independent Datalog rule module is used for deductive reasoning, the self-adaptive process is realized, the system code quantity is greatly reduced, the coupling of the system codes is reduced, the self-adaptive operation logic is more efficient and simpler, and the problems of code rewriting and redeployment caused by dynamic scene updating are avoided.

Description

technical field [0001] The invention belongs to the field of unmanned system simulation, in particular to an unmanned car simulation method. Background technique [0002] In the field of unmanned system research, the adaptive ability of the system has received extensive attention. Adaptive ability, first proposed in the "open world" concept, it requires that the software can adapt to changes and dynamically adjust under the changing working environment, and has the ability of self-organization. Opposite to the concept of "open world" is the "closed world" of traditional software development, that is, the system and environment are immutable, and the logic and environmental information of the system are a priori. This traditional software development method is no longer applicable to the operation logic of the unmanned car, because the environment where the unmanned car is located must be constantly changing. If the traditional software development method is used, every time...

Problems solved by technology

When the programming language itself does not have deductive reasoning ability, the operating logic often contains a large number of conditional judgments and action-triggered statements, resulting in cumbersome system codes and low execution efficiency
