12 Jul 1996TL;DR: In this paper, the authors present a configurable schedule of settings that defines actions to be taken when a deficiency in the messaging software or a messaging link connecting messaging systems is detected.
Abstract: The present invention is directed to systems and methods for automatically monitoring the status of messaging software. When a deficiency in the messaging software or a messaging link connecting messaging systems is detected, the invention refers to a configurable schedule of settings that defines actions to be taken. Actions may include identifying at least one message that should be sent when a particular warning or alert occurs, identifying the method to send the message, identifying the destination or recipient of the message, and identifying a time to send the message. In addition, the schedule allows an administrator to configure operation times for notification methods. If the system decides that notification should be sent via a method that is not allowed to operate until a certain time, notification using that method will be delayed until the allowed time. Using the time to send the notification, the method that should be used to send the notification, and the time that the identified notification method is allowed to execute, the system schedules the notifications and sends the appropriate notifications when the time arrives. If indicated by the schedule, the system will also undertake automatic repair of the deficiency by performing such actions as stopping and restarting various software components, executing new software components, or performing an automated shutdown and restart of the affected system. An administrator can prevent attempts at automated repair by placing a system in a maintenance mode which locks out all automated repair actions but leaves notification actions intact.

TL;DR: In this paper, a remote maintenance technology for substation automation equipment based on general service protocol (GSP) is first proposed, and the brand new system architecture is designed which involves the service management center, the maintenance center, and substations.
Abstract: With the rapid development of China's economy, smart grid has been built in an all-round way. As an important basic node of smart grid, the technical complexity of smart substation automation system is getting higher and higher. Once a fault occurs, if not handled in time, it will seriously affect the safety and stability of the power grid, which poses a great loss to economic production activities. The traditional mode of local maintenance has the drawbacks of high time consuming, low efficiency, and heavy workload. To solve these problems, a remote maintenance technology for substation automation equipment based on general service protocol (GSP) is first proposed in this paper, and the brand new system architecture is designed which involves the service management center, the maintenance center, and substations. The standardized interaction mechanism, integrated deep security protection methods, and flow control strategy are adopted to ensure the standardization, security, and reliability of the remote maintenance system. Finally, the effectiveness of the proposed methods is successfully demonstrated, and the comprehensive performance of the remote maintenance system is evaluated by comparing with the traditional local maintenance mode.

TL;DR: In this paper, the authors present a diagnostic method for assessing intermittent failures which occur in the components and systems of material handling vehicles, using an on-board microprocessor and display to allow an operator to determine whether any intermittency is present in the internal systems.
Abstract: The present invention features a diagnostic method for assessing intermittent failures which occur in the components and systems of material handling vehicles. The material handling vehicle of this invention uses an on-board microprocessor and display to allow an operator to determine whether any intermittency is present in the internal systems. The microprocessor is programmed to analyze each system during normal vehicular operation. The program is divided into two vehicular modes, "normal operating" and "program". During the normal operating mode, the vehicle operator is warned of a problem by different audible tones and patterns. A fault code scrolls across the vehicle display screen, indicating the nature of the failure. The program mode can then be entered to assess just where the problem is located. The program mode is divided into three additional modes: "maintenance mode", "configure mode" and "learn mode". The vehicle is selected for maintenance diagnostics during the program mode, and then switched back to the normal operating mode, where the intermittent failures can be diagnosed. The maintenance mode is divided into three diagnostic surveys: output controls, digital input measurements for analyzing switches and encoders, and analog input measurements for testing voltages and potentiometers. Each system in the vehicle can be analyzed by selecting the proper maintenance code.
