NOVELTY - A heating picture control system belongs to the technical field of heating and ventilating device, specifically comprising a Hall current sensor, a first switch and a second switch; a PLC unit and a graphene heating plate; the Hall current sensor collects the current data of two ends of the graphene heating plate to determine the change condition of the resistor; it can effectively collect the change condition of the resistance value of the graphene heating plate in real time; and it does not affect the normal work of the heating picture; once the heating picture has the condition of short circuit in the gate; the PLC controller can quickly judge and control the second switch to cut off the power supply circuit; it radically eliminates the potential safety hazard; In addition, the system has simple structure, can be integrally installed with the heating picture, small occupied space, at the same time, the use safety of the heating picture is ensured.
