Abstract

The invention discloses a municipal facility fault prediction method and device. The method comprises the following steps: acquiring data of a plurality of state classification features of municipal facilities collected in real time, pretreatment, determining whether the plurality of state classification features satisfy a condition independence hypothesis and/or a weight equal hypothesis, if not,optimizing a preset naive Bayesian classifier through the Pearson correlation coefficient and/or entropy method according to the plurality of state classification features; and inputting the preprocessed data into an optimized naive Bayesian classifier to obtain the fault prediction probability of the municipal facilities, and determining the fault prediction of the municipal facilities accordingto the sequence of the fault prediction probability of the municipal facilities in all the fault prediction probabilities of the municipal facilities. The problems that at present, municipal facilitymaintenance is low in efficiency and high in cost, and requirements cannot be matched in time due to the fact that more citizens actively report repair and conduct manual inspection can be solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of fault prediction, and in particular to a method and device for fault prediction of municipal facilities. Background technique [0002] In recent years, with the rapid development of urbanization in my country, the number of users of urban municipal facilities has increased, and corresponding equipment failures and maintenance requirements have occurred frequently, which restricts and hinders the further development of cities. In many cases, simply increasing investment in facility maintenance or adding manpower can easily lead to an imbalance between demand and supply, that is, resources allocated during the peak flow of people are likely to be idle at other times and cause waste. Therefore, how to fundamentally improve the maintenance efficiency of existing municipal facilities is the key to solving the problem.
