Development of Database System for Overhead Power Transmission Line Inspection Robot

In order to store and manage the basic information and inspection task for overhead high voltage power transmission line inspection robots, a database system is built up. This database system can store and manage such information as sensor information, historical data, report, inspection task, and line fault detected. Moreover, there is a simple line fault expert database in the database system developed for automatic line fault detection of the robots. SQLite is adopted as the backend database in this system. According to the specific requirements of the actual inspection application, the E-R model of the database system is designed, which is composed of two parts: sensor data model and line inspection model. Application experiments reveal that this database system can accomplish the information storage and management work for inspection robots.
