Embodiment Construction
[0024] Embodiments of the signal processing-based electrothermal regulation platform of the present invention will be described in detail below with reference to the accompanying drawings.
[0025] The most basic content of signal processing includes transformation, filtering, modulation, demodulation, detection, and spectrum analysis and estimation. Transformation such as types of Fourier transform, sine transform, cosine transform, Walsh transform, etc.; filtering includes high-pass filtering, low-pass filtering, band-pass filtering, Wiener filtering, Kalman filtering, linear filtering, nonlinear filtering, and Adaptive filtering, etc. Spectrum analysis includes the analysis of known signals and random signals. Usually, the most common research is the analysis of random signals, also known as statistical signal analysis or estimation. It is usually divided into linear spectrum estimation and nonlinear spectrum. Estimation; spectral estimation includes periodogram estimation,...

The invention relates to an electric heating regulation and control platform based on signal processing, and the platform comprises an electric heating regulation and control device which is connected with a resistance heating array of an electric blanket body, and is used for adjusting the specific value of a transmission current transmitted to the resistance heating array based on the received estimated entity volume; the resistance heating array consists of a plurality of resistance heating units which are connected in parallel, and the plurality of resistance heating units which are connected in parallel are uniformly distributed in the electric blanket body; and the switch control device is used for recovering or stopping power supply to the electric heating regulation and control device and the resistance heating array. According to the invention, a visual analysis mechanism of the current user volume executed while the user opens the electric blanket body can be designed for a subdivided application scene that the user enters the use starting stage of the electric blanket body, and the output power of the electric blanket body in the use starting stage is adjusted based on the analyzed current user volume. Therefore, two different requirements of energy saving and heating effect of the electric blanket body are met simultaneously.
Description
technical field [0001] The invention relates to the field of electric blanket body control, in particular to an electric heating control platform based on signal processing. Background technique [0002] Electric blanket, also known as electric mattress, is a contact electric heating appliance. It weaves or sews a special cable-type electric heating element with a standard insulation performance into the blanket in the shape of a snake, and emits heat when it is energized. [0003] Electric blankets are mainly used to increase the temperature in the bed when people sleep to achieve the purpose of heating. It can also be used for dehumidification and dehumidification of bedding. It consumes less power, has adjustable temperature, is easy to use, and is widely used, and has a history of more than 100 years. Pregnant women, children, and the elderly can safely use the non-radiation electric blanket. [0004] At present, as an important branch of electric heating devices, ele...
