Abstract

The invention discloses a method and a device for determining a temperature change trend and electronic equipment. The method comprises the following steps: collecting a plurality of temperature observation data of a target observation point in a target time period corresponding to a sunset moment of the same day to a sunrise moment of the next day; according to the obtained temperature observation data corresponding to different moments, performing fitting operation on a preset fitting function by using a preset fitting algorithm until an error value between the temperature observation data and corresponding fitting data in a fitting result meets a preset error condition, and obtaining cooling intensity according to the fitting result; calculating according to the steps to obtain the cooling intensity of each day in multiple consecutive days; According to the cooling intensity of each day in the continuous multi-day, determining the temperature change trend in the multi-day by using a preset trend detection algorithm. The temperature characteristic of the day is represented by extracting the cooling intensity capable of representing the stable cooling trend, the advantage in the aspect of high-frequency disturbance resistance is obvious, and the accuracy of a temperature trend analysis result is improved.

Description

technical field [0001] The invention relates to the technical field of data analysis, in particular to a method, device and electronic equipment for determining a temperature change trend. Background technique [0002] The analysis of temperature change trend plays an important role in scientific research on climate change, weather forecasting, fire risk assessment, and earthquake monitoring. The existing temperature change trend detection method mostly uses the temperature observation value at a specific time or the average value of multiple temperature observation values ​​at a specific time to represent the temperature value of the day, and analyzes the temperature change trend by continuously acquiring the temperature value for multiple days. [0003] However, the temperature observation value at a specific time is used to analyze the temperature change trend. Due to the influence of climate conditions and the accuracy of observation equipment, the temperature observatio...
