A remote maintenance and testing system for the network of lighting location finder is presented. Based on the maintenance method of lighting location finders, the proposed system produces the key information of realtime monitoring and running status of the lightning location finder and provides the assessment and the alarm of the equipment malfunction in fully automatic manner. Particularly, the system is implemented by using the current stateoftheart Web visual techniques with a friendly graphical user interface (GUI). The system provides robust realtime interaction with the hardware of the network. The proposed system overcomes the problems presented by the conventional maintenance mode, such as failing to response quickly to the malfunction of the distributed stations. The proposed system shows promising in the lightning location network maintenance, and can obtain a sound efficiency and accuracy performance.
