Public water drinking device-based fault diagnosis method

Abstract

The invention discloses a public drinking water device-based fault diagnosis method. The public drinking water device-based fault diagnosis method comprises the steps of transferring a detection dataset to a cloud server by a drinking water device arranged at each place; building a test matrix for each detection data set under a time frame, wherein the test matrix comprises multiple groups of parameter vectors taking running parameter types of drinking water devices as units; building a trend map of the running parameter type according to the parameter vectors, and acquiring the trend maps ofall parameter vectors; and taking the test matrix and all trend maps as a test sample, inputting the test sample into a neural network-based fault identification model, and acquiring a fault type, afault position and fault early-warning. The public drinking water device-based fault diagnosis method can be applied to joint management and fault detection of a large amount of public drinking fountains within a wide range and is rapid in response speed and accurate and reliable in fault positioning and fault identification, the requirement of a user on experience is reduced, the fault type and the fault generation position can be rapidly and accurately obtained, and an accurate repair guidance parameter can be provided for a maintainer.

Description

technical field [0001] The invention belongs to the technical field of public equipment fault diagnosis, in particular to a fault diagnosis method based on a public drinking water device. Background technique [0002] With the development of the sharing economy, the sharing economy has gradually penetrated into every corner of our lives. Public drinking water equipment has also become a part of the sharing economy. At present, public water dispensers are often installed in public places so that people can drink delicious drinking water at any time. [0003] However, shared public drinking water equipment is placed in various locations in public places, with a wide range of distribution and scattered locations. Maintenance personnel need to conduct regular inspections and checks to report the information of the faulty machine before maintenance by maintenance personnel. During the inspection process of the maintenance personnel, because the maintenance personnel are not prof...

AI Technical Summary

Problems solved by technology

[0004] This causes a waste of manpower and material resources, and requires a large number of personnel to participate in maintenance and repair work

Complicates the work of the maintenance personnel and greatly reduces the maintenance efficiency

The maintenance efficiency of the entire public drinking water installation is extremely low, often causing the drinking water equipment to stagnate for a long time, and it is impossible to perform fault maintenance on the equipment in time
