Embodiment Construction

[0060] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present application, and Not an exhaustive list of all embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0061] In the process of implementing the present application, the inventors found that during the degradation process of the power supply, the action of its internal feedback regulation circuit will increase the fluctuation degree of the power supply case temperature, which is manifested as an increase in the variance of the case temperature. Therefore, the shell temperature variance can be used as the degradation...

Abstract

The invention provides a power supply shell temperature variance obtaining method, electronic equipment and a computer storage medium, and the method comprises the steps: obtaining the environment temperature data of a rail transit signal power supply system and the shell temperature data of a power supply in real time in a service process; the influence of the environment temperature data on the shell temperature data is removed, and the processed shell temperature data is obtained; grouping the processed shell temperature data; different shell temperature values in each group and the number of the different shell temperature values are determined; and determining the shell temperature variance of each group of the power supply according to the different shell temperature values in each group and the number of the different shell temperature values. According to the method provided by the invention, the influence of the environment temperature data on the shell temperature data is removed according to the environment temperature data of the rail transit signal power supply system and the shell temperature data of the power supply to obtain each group of shell temperature variances of the power supply, so that the real-time and accurate acquisition of the shell temperature variance data is realized.

Description

technical field [0001] The present application relates to the technical field of rail transit, and in particular to a method for obtaining the temperature variance of a power supply casing, electronic equipment, and a computer storage medium. Background technique [0002] The rail transit signal power supply system suffers from various stresses for a long time during its service, and it inevitably degrades. Its degradation will seriously affect the normal operation of its back-end load equipment. Therefore, it is of great significance to obtain the degradation characterization parameters of the power supply in real time during the service process for evaluating its degradation state and ensuring the safety and reliability of the rail transit signaling system. [0003] At present, the output voltage and ripple voltage are often used as the degradation characterization parameters of the power supply. According to the change degree of the degradation characteristic parameters...
