Abstract

PURPOSE:The leak coaxial cable is provided at the boundary area of each zone where electric wave interference occurs, and the power supply system for electric wave is switched on the ground when the moving object passes through the boundary area. Thus, the communication incapable range is eliminated. At the same time, the operational flexibility of each zone can be increased.
