Research on maintenance cycle decision and support system design for wireless sensor network equipment

Maintenance cycle decision is an issue needed to be taken into account for wireless sensor network for it has too many equipment and too many kinds of maintenance events. This paper studied the issue based on case-based maintenance theory for energy-saving and emission-reducing purpose.It gave the models of anticipated loss of maintenance and failure for three types of maintenance events. Followed was a particle swarm optimization algorithm to solve the nonlinear maintenance cycle decision problem. Based on the models and the algorithm, developed a decision support software under the WinCC environment. The software can forcefully support the maintenance of wireless sensor network equipments with the in-line knowledge and the maintenance time worked out.
