The embodiment of the utility model provides an in divide into M group with a plurality of thermal resistance, a switch is corresponded to a set of thermal resistance, and each switch timesharing switches on. The main control module 10 collects N voltage signals each time (the main control module 10 determines a temperature value corresponding to the thermal resistor according to the collected voltage signals), and the collection can be completed all times. For example, there are M × N thermal resistors, and the prior art requires M × N connection lines to connect to the main control module 10.
