Heat Tracing Control Method Based On Petri Nets

In recent years, too few heat source tracking control method, lack of flexibility,so that research and development in this field is slow. With the heat tracing increasingly complex environment, a large number of heat-related tasks consequent track, need for a method of controlling the heat source can be automatically tracked.How effective control method for quickly and accurately track the heat source is a strong theory and application value research.In this thesis, a set up by using Petri net models for mobile robot control, to achieve its self-tracking heat source, so as to effectively track the heat source to provide a suitable method. By analyzing the behavior characteristics of heat tracing robot establish Petri net model, according to the established model of the control logic,the preparation of its control program, source tracking mobile robot. When the mobile robot walking, due to environmental temperature changes, the temperature of the perceived value of the robot will change. To perceive the subtle changes in temperature, to achieve traceability robot source, the need for complex modeling expertise. The traditional rule-based knowledge modeling approach lacks logic and reasoning ability visibility, integrity and internal, not adequately express the relationship between the overall and the internal logic and the interaction mechanism between knowledge. The Petri net with better visualization, integration, internal logic expression, and automated reasoning. Therefore, this paper will combine Petri nets knowledge regular library robot control. Finally, based on Petri net model established by Proteus simulation and dolly to achieve the robot tracking heat.This article is based on Proteus as a heat source tracking control algorithm development and verification of basic platform, developed with heat tracing basic function module, the main source acquisition module, heat display module, the decision-making process and tracking source module module. Multiplexing the heat collection, decision-making process as well as some of the key technologies andcapabilities to track heat and so on. Especially in from close range in the heat source to the heat source and heat efficient track positioning. In addition, the system in the smaller temperature difference between the heat source and the surrounding still has good tracking and positioning effect, have to achieve a reliable source tracking capabilities in a complex environment. In the heat tracing process temperature acquisition by walking robot, stop, turn left, turn right between the four acts to achieve self-switching. Due to the above acts between concurrent, asynchronous coupling and autonomous decision-making, etc., using Petri net modeling the system.In this paper, Petri net model established, to prepare the corresponding control procedures applied to the simulation software and physical verification platform.Through experiments and analysis, to verify the source of the proposed tracking control method based on Petri nets for robots provide a suitable heat source tracking method.
