INTRODUCTION
Circuit breakers are crucial components for power system operations. They play an important role in switching for the routine network operation and protection of other devices in power systems. To ensure circuit breakers are in healthy condition, periodical inspection and preventive maintenance are typically performed. The maintenance schedules and routines usually follow the recommendation of circuit breaker vendors, although the recommended schedules may be conservative.
The mobile agent software provides a flexible framework for mobile agent applications. An agent application program can travel through the internet to the computers where the mobile agent server or transporter is running. The mobile agent software also supports Distributed Events, Agent Collaboration and Service Bridge. Compared with client server systems, an agent can process the data locally and thus reduce the network traffic. Besides, the Java platform encapsulates the network layer from the agent, which makes the programming easier. The mobile agent software may fit very well in the circuit breaker maintenance scenario.
Mobile Agent Software
An agent is a proactive software component, which is capable of acting reasonably to accomplish tasks on behalf of the user. An agent should be autonomous and have sound intelligence. A good software agent should be able to adapt to the changing environment; it may also be helpful to have the ability to exchange knowledge with other agents.
Agent-based programming offers greater flexibility and adaptability than component-based programming. Compared with object-oriented software engineering, agent-oriented software engineering uses a set of high-level, flexible abstractions to represent systems. Agents communicate with each other by passing messages or by synchronization.
CONCLUSION
Utilizing mobile agent techniques, the convenience and speed of accessing and generating maintenance data will be improved. With increasing complexity of circuit breaker equipment, more information is needed to perform the maintenance work, so an efficient data communication exchange becomes very important. Mobile agents can process information locally with less network bandwidth consumption. Also its ability to provide reliable transmission on disconnected or low quality networks is an important merit
Mobile agent computing easily facilitates the integration and automation of the maintenance process, starting from the generation of work orders to the completion of the
maintenance report. The entire process may involve multiple entities and steps. Thus, an automated procedure is highly desirable. With the ability to collaborate and update agent
itineraries adaptively, the mobile agent software provides an ideal framework for modeling and supporting the maintenance workflow.
Furthermore, mobile agent computing also provides the means by which real-time and off-line data can easily be integrated into a single distributed maintenance management system. Using real-time monitoring data, the maintenance system can evaluate the condition of devices, which makes predictive maintenance possible. The integration of real-time data may be utilized to improve the maintenance management decisions. The platform independence feature of mobile agents provides interface and support for great variety of devices.
