Temperature control system, detection system and temperature control method for micro-fluidic chip

A temperature control system for a micro-fluidic chip, comprising:

• a circuit structure in a functional layer of the micro-fluidic chip, corresponding to a reaction zone of the micro-fluidic chip, and comprising a plurality of thermistors and a plurality of ports, wherein the plurality of ports comprises input ports and output ports, and the input ports are electrically coupled to the output ports are electrically through at least one of the plurality of thermistors to form application circuits, respectively;
• and
• a controller electrically coupled to each of the plurality of ports and configured to select a first input port and a first output port among the plurality of ports, such that the circuit structure is configured to form a first application circuit as a heating device, and to select a second input port and a second output port among the plurality of ports, such that the circuit structure is configured to form a second application circuit as a temperature sensor,
• wherein the first application circuit;
• comprises the first input port, the first output port and a first number of thermistors among the plurality of thermistors electrically coupled between the first input port and the first output port, and the second application circuit comprises, the second input port, the second output port, and a second number of thermistors among the plurality of thermistors electrically coupled between the second input port and the second output port,
• wherein the controller is further configured to:
• obtain a current temperature of the reaction zone, in response to the circuit structure being configured to form the second application circuit as the temperature sensor;
• and
• select the first input port and the first output port, in a case where the current temperature is lower than a first preset temperature, such that the circuit structure is configured to form the first application circuit as the heating device to heat the reaction zone until a temperature of the reaction zone reaches the first preset temperature.
