Detailed ways

In order to be concise and intuitive in description, the solution of the present invention is explained below by describing several representative embodiments. A large number of details in the embodiments are only used to help understand the solutions of the present invention. However, it is obvious that the implementation of the technical solution of the present invention may not be limited to these details. In order to avoid unnecessarily obscuring the solution of the present invention, some embodiments are not described in detail, but only a framework is given. Hereinafter, "including" means "including but not limited to", and "according to..." means "at least according to..., but not limited to only according to...". Due to Chinese language habits, when the quantity of a component is not specifically indicated below, it means that the component can be one or more, or it can be understood as at least one.

In the embodiment of the present invention, in order to more intuitively represent the one-dimensional time series operating data of the device, it is considered that the one-dimensional time series data is represented by a two-dimensional imaging method according to the present invention.

In order to make the technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to illustrate the present invention, and are not used to limit the protection scope of the present invention.

Fig. 1 is an exemplary flowchart of a method for representing device operating data in an embodiment of the present invention. As shown in Figure 1, the method may include the following steps:

Step S102: Obtain one-dimensional time series operating data of a device, where the one-dimensional time series operating data consists of values collected based on each time point.

In this step, the one-dimensional time series running data can be different for different devices. Taking a transformer as an example, its one-dimensional time series operation data may include voltage time series data, power time series data, or current time series data.

For example, taking the voltage time series data of a transformer device as an example, if the original data is drawn according to time points, the graph shown in FIG. 2A will be obtained. In Figure 2A, the abscissa is the time point, for example, there are more than 60,000 collection time points in two years, and the ordinate is the numerical value.

Step S104, based on an abscissa as a time period and an ordinate as the coordinate system of each time point in the time period, the value collected based on each time point is identified by a predetermined color value corresponding to the value In the coordinate system, an image is obtained. Among them, different values correspond to different color values. Wherein, the time period is determined according to the resolution of the one-dimensional time series running data.

For example, for the voltage time series data shown in Figure 2A, it is assumed that the determined time period is one day. Of course, the time period in practical applications can also be one week or one month, or 10 days, 15 days, 20 days, or 25 days. , 30 days, 40 days, etc. Any period that meets the requirements. The details can be determined according to actual needs and are not limited here. Then, a horizontal coordinate can be set to represent each day in two years, and the ordinate can represent a coordinate system at each time point of the day (taking the case of 96 collection time points per day as an example), and an image as shown in FIG. 2B can be obtained. In Fig. 2B, different grayscale color values are used for different values. The darker the color, the larger the value, and the lighter the color, the smaller the value. In practical applications, different color values can be used for different values. For example, the color range can be expressed from dark blue to dark red. The higher or lower the value, the higher the intensity of red or blue, and vice versa. The same is true. In practical applications, the effect of using colored color values for representation will be better.

It can be seen intuitively from Figure 2B that the voltage value changes with time, that is, the voltage value is higher at the beginning of each day, and there is also a high value at the end of the day, while the voltage value is lower in the middle of the day. But if this is only based on the one-dimensional time series data shown in Figure 2A, it is difficult to see.

Further, since FIG. 2B is a two-dimensional image representation of the original time series data, it sometimes appears noisy due to the presence of noise. In order to facilitate the extraction of useful features or patterns from the image in subsequent use, a filter may be further used to filter them in the embodiment of the present invention, thereby removing high frequency noise, and obtaining the filtered image shown in FIG. 2C. Among them, the filter can be any function as long as it can remove high-frequency noise. For example, in this embodiment, a two-dimensional Gaussian filter can be used to remove noise or tiny spots in FIG. 2B.

It can be seen that by superimposing the one-dimensional time series operating data in each time period to convert or reshape it into a two-dimensional image, the converted two-dimensional image can more intuitively represent the operating state of the transformer, for example, when When the color range from dark blue to dark red is used, the red area can indicate the high operation area or cycle of the transformer, and the blue area can indicate the low operation area or cycle of the transformer.
