Beschreibung
Zusammenfassung:	The invention discloses a heater loop control method which comprises steps as follows: the passing current of a heater is detected in real time, when the passing circuit is higher than a preset value, a work loop of the heater is opened; otherwise, the work loop of the heater is closed; when the work loop cannot be opened, secondary protection is started. With the adoption of the technical scheme, the passing current passing through the heater is detected, the work loop of the heater is controlled to be in an automatically opened or automatically closed state, when automatic opening fails, secondary protection is started, so that the running safety and reliability of the heater loop are improved, and engine failures are reduced. The invention further discloses a system applying the control method as well as the heater loop.
