Embodiment 1

[0073] The method of the present invention is used to evaluate the health of the switching power supply in a communication base station. The goal is to evaluate the change trend of the health of the switching power supply within a month, and to score the health of the switching power supply every other day, that is, the scoring interval is 1 day.

[0074] S1. Collect the alarm data of the switching power supply of the communication base station, and write the alarm data into the database according to the time sequence of alarm occurrence over a period of one month.

[0075] S2: Eliminate invalid data such as missing, repeated, and instantaneous interruptions in the alarm data, and extract data attributes such as the name of the alarm event, the alarm severity, the alarm occurrence time, the alarm end time, and the number of alarm repetitions.

[0076] Missing alarm means that the alarm data information is incomplete and some field values ​​are empty. Instantaneous alarm inter...

Abstract

The invention belongs to the field of device health degree analysis, and particularly relates to an alarm data analysis based device health degree estimation method and apparatus. The alarm data analysis based device health degree estimation method and apparatus uses an alarm event as an estimation index, determines index score and index weight according to alarm features, can objectively estimate the health degree of a device, and can provide a basis for instructing later device failure management and maintenance.

Description

technical field [0001] The invention mainly belongs to the field of equipment health degree analysis, and in particular relates to an equipment health degree evaluation method and device based on alarm data analysis. Background technique [0002] The equipment health degree refers to the good degree of the overall operation of the equipment, and is a comprehensive evaluation of the operation status of the entire equipment. A commonly used health assessment method is health assessment based on equipment operating state parameters, that is, by monitoring the running equipment and obtaining equipment state parameters to evaluate the state. However, in practical applications, the equipment is encapsulated in a cabinet, and it is difficult to obtain the equipment parameters in operation, and most of them are tested by manual discharge test and conductivity test, which is not only complicated, but also has strong professional requirements. [0003] There are literature reports on...
