Pulse type sensor data acquisition method applied to cooking utensil, and cooking utensil

Abstract

The invention discloses a pulse type sensor data acquisition method applied to a cooking utensil, and the cooking utensil. According to the invention, an upper cover and a pot body of the cooking utensil are coupled, connected and communicated through a coupling connector; and a control chip communicates with a temperature sensor through a power supply carrier communication mode based on pulse counting so as to acquire temperature data. The acquisition method comprises the steps that N frames of temperature data are continuously acquired according to a set acquisition period, wherein the acquisition period is set according to a specified interference pulse period and / or interference pulse width, and N is an integer not smaller than 3; the N frames of temperature data is sorted according to size so as to obtain a sorting queue; and according to one or more pieces of intermediate data in the sorting queue, temperature data in which interference pulse is filtered out is determined. According to the invention, no circuit needs to be added, software filtering is adopted, specified interference pulses can be effectively filtered, more reliable temperature data can be left, temperature measurement accuracy can be improved, and a cooking process can be more reliably controlled based on a temperature measurement result.

Description

technical field [0001] The present application relates to the technical field of cooking control, in particular to a pulse sensor data acquisition method applied to a cooking appliance and the cooking appliance. Background technique [0002] At present, for similar cooking utensils such as electric rice cookers and electric pressure cookers, when they contain a top temperature sensor and the upper cover and the pot body are detachable, the coupling and docking method can be used. In order to improve the coupling reliability, a two-wire docking method is used. In this connection mode, the communication line and the power supply line are multiplexed, and the control chip can communicate with the top temperature sensor by means of power supply carrier communication to collect top temperature data. [0003] In the prior art, contact resistance is generated at the coupling connection, and the contact resistance will cause a large error in the analog signal passing through the cou...
