Further, measuring circuit adopts resistance measurement bridge, electric heating element R
LAs an arm of measuring bridge, the electrical quantity of its measurement inserts amplifying circuit A, inserts cpu control circuit by analog to digital conversion circuit ADC again, and measuring circuit adopts divider resistance formula circuit, and electric heating element is as one of divider resistance.
The sign register adopts autotelegraph electricity wiping formula storaging chip, and electric heating element can be heating wire, Electric radiant Heating Film, electric heating paper tinsel, carbon fiber, electric heating powder, electric-heating coatings etc.
The utility model is by the improvement to controller circuitry, and making the electric heating element in the clothing is heat converter, is again temperature sensor simultaneously, such technical scheme, and advantage is:
1, omitted the temperature-sensitive transducer that tradition adds, reduced the failure rate of transducer, the wire structures of electric heating clothing inside is also greatly simplified;
2, the corresponding identification with electric heating element of sign register makes exchange, observing and controlling temperature precision problem between the electric heating element accessory obtain solution;
3, produce molding process simple, reduce cost;
