Problems solved by technology
[0005] (3) When the measured data is uploaded from the ground to the ground, it is often necessary to add additional communication cables for signal transmission, and the required cables are multiplied;
[0006] (4) Especially in some large-scale and wide-area underground measuring devices or when powering and communicating with deep underground or underwater measuring devices, the application of multiple cables will increase the system cost rapidly, reduce reliability, and reduce practicability. become worse

Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] see figure 1 , this embodiment includes a ground power supply system and a signal receiving system installed above the ground, an underground measurement and control system installed under the ground, and a single insulated wire 1 connecting the ground power supply system and signal receiving system with the underground measurement and control system . From figure 1 It can be seen from the figure that the ground power supply system includes a DC power supply 3, the positive pole of the DC power supply 3 is grounded, and the negative pole is connected to the core 2 on the upper end of a single insulated wire 1 through a signal receiving system; the signal receiving system includes a current sampling resistor Rs, a current sampling resistor Rs The upper end is connected to the negative pole of the DC power supply 3, and the lower end is...

The invention discloses a power supply and communication device for underground measurement. The device is characterized by comprising a ground surface power supply system and a signal receiving system which are installed above the ground, an underground measuring and control system installed underground and a single insulation lead connecting the ground surface power supply system, the signal receiving system and the underground measuring and control system. The underground measuring and control system is arranged in an insulated water-proof enclosed casing. The grounded end of the underground measuring and control system is led out from the casing and grounded, and the other terminal of the underground measuring and control system and led out from the casing is connected with a line core of the underground end of the single insulation lead. The ground surface power supply system comprises a direct current power supply, the positive pole of the direct current power supply is grounded, and the negative pole is connected onto a line core of the ground surface end of the single insulation lead through the signal receiving system. The device is simple in principle, low in cost, easy to implement, high in reliability, suitable for long-term power supply of underground, underwater, under-shaft and in-shaft medium and small power measuring and control systems and data communication low in baud rate.
Description
technical field [0001] The invention belongs to the technical field of underground measurement systems, and in particular relates to an underground measurement power supply and communication device. Background technique [0002] At present, underground measurement systems are usually powered by batteries, or powered by a power supply loop composed of two or more cables, and communication cables or optical cables are also required for communication. Specifically, when the underground measurement and control system needs to work for a long time, the traditional method mainly has the following problems: [0003] (1) When the battery is used for power supply, the working time is limited by the battery capacity, and it is inconvenient to replace the battery, so it is difficult to ensure the working needs of the long-term or long-term underground or underwater measurement system; [0004] (2) When using a power line to connect the ground DC power supply to supply power to the und...
