| 摘要 | PURPOSE:To miniaturize the transmitter and to decrease radio wave interference with plant equipment by coupling signals in terms of capacitance with a copper plate provided to a shield type parallel 2-wire line installed along with a running path of a mobile and collecting power through contact. CONSTITUTION:A check apparatus (e.g., temperature sensor, radioisotope detector or the like) mounted on a mobile body 1 is moved and stopped by an operating panel 4 at the outside of a case 2 along a running route 3 around a main device provided in the case (barrier) 2 and the information of a district is collected. The transmission route 3 is formed with a shield parallel 2-wire line and a copper plate, the signal transmission is coupled with a capacitance with the copper plate and the power is fed by the contact collecting system. Thus, external operation is conducted easily externally to a small-sized device and this system is suitable for maintenance and inspection of an atomic reactor or the like. | ||||||
