Abstract
Disclosed is a control strategy for a hot surface igniter. On the basis of a hardware circuit of the hot surface igniter and a software algorithm, a working time of the hot surface igniter is divided into t1, t2, . . . , and tn time periods. In each time period, an output voltage or an output power of the hardware circuit is adjusted by the software algorithm to make the hot surface igniter reach an expected temperature. Through the control strategy of the disclosure, ignition time of the hot surface igniter may be easily controlled. The requirements of a user of igniting in a short time are satisfied.
Claims8
A control strategy for a hot surface igniter:
- comprising:
- dividing a working time of the hot surface igniter into t1, t2, . . . , and tn time periods on the basis of a hardware circuit of the hot surface igniter and a software algorithm, and
- adjusting an output voltage or an output power of the hardware circuit by the software algorithm to make the hot surface igniter reach an expected temperature, wherein adjusting comprises:
- step I, obtaining a working time-temperature change curve that meets requirements according to product characteristics and application scenarios of the hot surface igniter;
- step II, dividing the working time of the hot surface igniter in step I into t1, t2, . . . , and tn time periods;
- step III, in each time period, controlling, by the software algorithm, the output voltage or output power of the hardware circuit to make the hot surface igniter reach a temperature value in the time period.
