The invention discloses a control method and system for an LPG vaporization device, wherein the method comprises the steps: collecting a real-time temperature signal, and carrying out preprocessing of a real-time temperature signal; performing first AD conversion or second AD conversion on the preprocessed signal according to preset temperature control precision; comparing the real-time temperature data obtained after AD conversion with a preset electromagnetic valve opening temperature threshold value, and when the real-time temperature data reach the preset electromagnetic valve opening temperature threshold value, turning on an electromagnetic valve to achieve LPG supply; according to the real-time temperature data after AD conversion, carrying out PI D adjustment on the working frequency of a solid-state relay, so as to enable the heating temperature to fluctuate within a preset range; and when the real-time temperature data after AD conversion is abnormal, controlling the heating device to stop working, closing the electromagnetic valve, and stopping acquisition of the output signal of the temperature measuring device. The problems that an existing LPG vaporization device control system is complex, high in cost and large in size are solved.
Description
technical field [0001] The invention relates to the technical field of LPG vaporization device control, in particular to a control method and system for an LPG vaporization device. Background technique [0002] The dry vaporizer is small in size and saves energy. Compared with the conventional water bath, its high efficiency and high reliability will surely be widely used in the future. [0003] The current LPG vaporization device generally adopts the water bath type, which has large energy loss, large footprint and low heat transfer efficiency, which limit the further development of LPG vaporization devices; and the dry gasifiers used in the market are all The control method of temperature controller + power relay + solid state relay is adopted. This control method has low sensitivity and single control mode, and cannot handle the damage of the external temperature probe or the abnormal temperature, both of which will cause the gasifier to heat up. Failure, the situation i...
