Claim 2:
3. The electrical control system for minimally invasive tumor therapies according to claim 2, wherein in the refrigeration working medium perfusion module, the first working medium storage tank being a refrigeration tank body, the first external working medium container being a Dewar vessel, the Dewar vessel being connected with the refrigeration tank body by means of a Dewar conveying pipeline; the refrigeration working medium perfusion module further comprises a refrigeration tank perfusion port insertion detection unit; and
the control module is further configured to:
detect, when the received liquid level of the first working medium storage tank of the refrigeration working medium perfusion module is lower than the first liquid level threshold value, whether the Dewar conveying pipeline is connected with the refrigeration tank body according to an insertion message sent by the refrigeration tank perfusion port insertion detection unit; and
determine, when the Dewar conveying pipeline is connected with the refrigeration tank body, 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.
