[Abstract]:With the development of science and technology, especially the development of robot technology, the inspection of transmission lines is gradually transferred from manual inspection to robot inspection, and the importance of inspection robot in transmission line inspection is gradually recognized. Due to the complex environment and various obstacles of transmission lines, the problem of automatic obstacle crossing of inspection robot is increasingly prominent, which is mainly reflected in the poor stability and low efficiency of obstacle crossing. Therefore, it is of great significance to study a new method to improve the stability and efficiency of automatic obstacle crossing. On the basis of in-depth study of production rules and expert system theory, this paper makes a full investigation of the current situation of the control system of the inspection robot, and discusses the goal and feasibility of the research. In this paper, a rule-based expert system method is proposed. The production rule and expert system theory are applied to the automatic obstacle control of the inspection robot. Combined with the structure of the robot, the degree of freedom of the robot and the characteristics of the sensor signal, this paper makes a deep research on the sensor signal acquisition circuit, the installation layout and the robot automatic obstacle crossing flow. This paper analyzes the functional requirements of the automatic obstacle crossing of the inspection robot, and designs the overall structure, function module and work flow of the automatic obstacle crossing expert system. This paper analyzes the concept of knowledge, the representation and acquisition of knowledge, and establishes the knowledge base of expert system by the combination of direct acquisition and indirect acquisition and knowledge representation of production rules. The maintenance flow of knowledge base is designed. On this basis, the reasoning mode, direction, conflict resolution strategy and Rete matching algorithm of the inference engine are discussed. Two search methods, blind search and heuristic search, are analyzed and compared. The blind search method and the improved Rete algorithm are used to design the reasoning flow of the inference machine. Based on the establishment of knowledge base and inference engine, Windows7 is used as operating system, Visual Studio 2010 is used as development tool, reasoning program is written in C # language, and SQL Server 2008 is used as database. A rule-based automatic obstacle crossing expert system for inspection robot is developed. It has good man-machine interface, automatic obstacle surmounting, knowledge base management, help and other functions. On the basis of the theoretical analysis, the experiment of the expert system is carried out with the automatic obstacle surmounting of the inspection robot, and the correctness and reliability of the theoretical analysis of the obstacle surmounting process are verified. The experimental results show the feasibility of applying the expert system theory to the automatic obstacle control of the inspection robot.
