1. An electrical control system for minimally invasive tumor therapies, wherein the system comprises a control module, a perfusion module and a power box, the perfusion module comprising a refrigeration working medium perfusion module and a heating working medium perfusion module, the refrigeration working medium perfusion module comprising a first working medium storage tank, a first tank liquid level meter, a first tank pressure sensor, a first tank deflation valve, a first liquid charging valve and a first external working medium container; and
the heating working medium perfusion module comprising a second working medium storage tank, a second tank liquid level meter, a second tank pressure sensor, a second tank deflation valve, a second liquid charging valve, and a second external working medium container;
the power box being configured to supply power to the control module and the perfusion module;
the control module being configured to receive working medium parameters sent by the first tank liquid level meter of the refrigeration working medium perfusion module and the first tank pressure sensor of the refrigeration working medium perfusion module, and to control, when the working medium parameters meet a perfusion condition, the first tank deflation valve of the refrigeration working medium perfusion module and the first liquid charging valve of the refrigeration working medium perfusion module to open or close, so as to input a refrigeration working medium from the first external working medium container of the refrigeration working medium perfusion module into the first working medium storage tank of the refrigeration working medium perfusion module;
wherein the working medium parameter sent by the first tank liquid level meter of the refrigeration working medium perfusion module is a liquid level of a working medium inside the first working medium storage tank of the refrigeration working medium perfusion module, and the working medium parameter sent by the first tank pressure sensor of the refrigeration working medium perfusion module is a tank pressure intensity of the first working medium storage tank of the refrigeration working medium perfusion module;
the control module further being configured to receive working medium parameters sent by the second tank liquid level meter of the heating working medium perfusion module and the second tank pressure sensor of the heating working medium perfusion module, and to control, when the working medium parameters meet a perfusion condition, the second tank deflation valve of the heating working medium perfusion module and the second liquid charging valve of the heating working medium perfusion module to open or close, so as to input a heating working medium from the second external working medium container of the heating working medium perfusion module into the second working medium storage tank of the heating working medium perfusion module;
wherein the working medium parameter sent by the second tank liquid level meter of the heating working medium perfusion module is a liquid level of a working medium inside the second working medium storage tank of the heating working medium perfusion module, and the working medium parameter sent by the second tank pressure sensor of the heating working medium perfusion module is a tank pressure intensity of the second working medium storage tank of the heating working medium perfusion module; and
the control module is further configured to:
determine, when a received liquid level of the first working medium storage tank of the refrigeration working medium perfusion module is lower than a first liquid level threshold value, whether a received tank pressure intensity of the first working medium storage tank of the refrigeration working medium perfusion module is less than a first pressure intensity threshold value; wherein the first liquid level threshold value is 95% or 90%, and the first pressure intensity threshold value is 300 KPa;
open, if the received tank pressure intensity of the first working medium storage tank of the refrigeration working medium perfusion module is not less than the first pressure intensity threshold value, the first tank deflation valve of the refrigeration working medium perfusion module, so as to reduce an internal pressure intensity of the first working medium storage tank of the refrigeration working medium perfusion module;
continue to determine whether the received tank pressure intensity of the first working medium storage tank of the refrigeration working medium perfusion module is less than the first pressure intensity threshold value; and
open, if the received tank pressure intensity of the first working medium storage tank of the refrigeration working medium perfusion module is less than the first pressure intensity threshold value, the first liquid charging valve of the refrigeration working medium perfusion module, so as to input the refrigeration working medium from the first external working medium container of the refrigeration working medium perfusion module into the first working medium storage tank of the refrigeration working medium perfusion module.
