Embodiment 1

[0031] A method for monitoring the life of a variable frequency fan used in an air disinfection and purification device, such as figure 1 shown, including:

[0032] Step S1: When the frequency conversion fan is powered on, collect the timing information of the current and send it to the server;

[0033] Step S2: The server extracts feature vectors based on the collected current sequence information, and inputs the extracted feature vectors into the trained first model to obtain the remaining life percentage, wherein the first model may use a convolutional neural network or the like.

[0034] Wherein, the training process of the first model includes:

[0035] Step A1: Obtain multiple sets of test data, where each set of test data includes the timing information of the energizing current of a variable frequency fan from the first energization to the end of its service life;

[0036] Step A2: For each set of test data, extract multiple eigenvectors, and obtain the remaining lif...

Abstract

The present invention relates to a method and a device for monitoring service life of a variable-frequency fan used for an air disinfection purification device. The method comprises the following steps: S1, when the variable-frequency fan is powered on, timing information of current is collected and sent to a server; S2, the server extracts a feature vector based on the collected current timing information; and the extracted feature vector is inputted into a trained first model to obtain a remaining service life percentage. Compared with the prior art, the invention determines the remaining service life of the variable-frequency fan through a networking mode and cloud technology, burden of the terminal is reduced; thereby the cost of the device is reduced and the more accurate result can be obtained.

Description

technical field [0001] The invention relates to a fan life detection technology, in particular to a method and device for monitoring the life of a variable frequency fan used in an air disinfection and purification device. Background technique [0002] With people's attention to health, air purification products have been greatly developed. At present, all purification products are equipped with life detection for filter elements, but they often lack the detection of fans. The reason is that the existing purification products are all It adopts the method of combining the filter screen with the fan, which has lower requirements on the fan and does not involve precise control of the fan. [0003] In this regard, some new purification products either do not have a filter element or require precise control of the frequency conversion fan, or due to the need to be normally open, the loss of the fan is large, and the fan needs to be maintained. Therefore, it is necessary for thes...
