Deep geothermal in-situ power generation multi-parameter integrated test system

The invention belongs to the technical field of thermal power generation, and provides a deep geothermal in-situ power generation multi-parameter integrated test system, which is characterized in that an evaporation interval, a heat insulation interval and a condensation interval are respectively defined on a pipe body, a working medium moves along the direction from the evaporation interval to the condensation interval, and the form of the working medium is switched according to a liquid-gas-liquid sequence; the evaporation section and the heat insulation section output electric energy outwards; the first measuring part is used for acquiring a parameter signal of a working medium in a testing process; the second measuring part is used for acquiring parameter signals of the inner cavity of the pipe body; the temperature measuring part is used for acquiring a temperature signal of the pipe body in a testing process; the liquid level meter is used for acquiring a liquid level signal of a working medium in the e
