Abstract

The invention relates to a method and a system for controlling atomization fumigation by multipoint temperature feedback, which solves the technical problem that an atomization fumigation chamber outputs water mist to realize equalization in space. The invention has the following technical proposal: the method sets the distribution positions of a multipoint temperature sensor and an atomizer according to boundary conditions which are determined according to the geometric shape of the inner space of the atomization fumigation chamber and include an airflow spraying direction angle formed by the ultrasonic atomizer nozzle and the change of temperature gradient caused by the speed. The system comprises a multipoint temperature collecting circuit, a central processing circuit, a heat regulating circuit, a water mist output circuit and a mist quantity regulating circuit. The invention has the advantages that the invention realizes the effect of accurate temperature control in the fumigation chamber by a multipoint temperature measuring and calculating model, has good use effect for users and has good economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of temperature feedback control, in particular to a method and system for multi-point temperature feedback control atomization fumigation. Background technique [0002] With the development of modern science and technology, atomized fumigation packs are gradually used in various fields, such as medical treatment, beauty, health care, etc. Since the mist emitted by the fumigation packs is distributed in the air, it is difficult to guarantee the heat balance. If the thermal balance cannot be guaranteed, it may cause a waste of resources and affect the effect of fumigation. If you want to control the heat balance well, it is necessary to measure and experiment with the temperature parameters output by the fumigation package, the parameters of the mist volume, the output point and the output direction in the space. For a long time, due to the large size of the fumigation bag, the uneven heat, and the difficulty...
