An underground power and communication measuring device

The present invention discloses a method for measuring underground power and communication devices. Techniques of the present invention are: it comprises ground power supply system and a signal reception system is installed above ground, underground installation of measurement and control system under the ground, as well as a single connection between the power supply system and ground receiving system and Control System Underground insulated wire; underground measurement and control system is installed in a closed housing insulation waterproof, underground ground measurement and control system from the ground after the housing leads from the case leads to the other terminal to the ground and Control system and the single insulated wires underground line terminal pin connector; ground power supply system includes a DC power source, the DC power supply positive ground, the negative single insulated wire to the ground terminal is connected to the core via the signal receiving system. Principles of the present invention is simple, low cost, easy implementation, high reliability, suitable for underground, long-term supply and baud rate underwater, underground, well small and medium-power monitoring and control system is not too high data communication.
