    • Maintenance information is collected by a sensor on an electric power cable installed in a manhole. The information is transmitted to a radio transmitter which is positioned in a vicinity of a bottom plane of an inner lid in an opening of the manhole. The information is transmitted by the radio transmitter, and received by a receiving antenna mounted on a bottom plane of the inner lid. On a top plane of the inner lid, an electrode, a connecting lead or a transmitting antenna is provided to be connected to the receiving antenna by an impedance matching circuit. The information is supplied to an outer lid in the opening of the manhole by the opening of the manhole by the electrode using a spatial coupling capacitance relative to the outer lid, or the connecting lead directly connected to the outer lid. Thus, the information is transmitted as a radio signal by the outer lid functioning as an antenna. Otherwise, the information is radiated below the outer lid by the transmitting antenna. Thus, the radiated information is leaked via the outer lid to the exterior of the manhole.
    • 维护信息由安装在人孔的电力电缆上的传感器收集。 信息被发送到位于人孔的开口中的内盖的底面附近的无线发送机。 信息由无线电发射机发送,并由安装在内盖底面上的接收天线接收。 在内盖的顶面上设置电极,连接引线或发射天线,通过阻抗匹配电路与接收天线连接。 通过使用相对于外盖的空间耦合电容或直接连接到外盖的连接引线,通过电极打开井孔,将信息提供给人孔的开口中的外盖。 因此,通过用作天线的外盖将信息作为无线电信号发送。 否则,信息通过发射天线辐射在外盖下方。 因此,辐射信息经由外盖泄漏到人孔的外部。
