Example 2

Referring to Figures 7 and 8, it is the second embodiment of the present invention, which provides a power distribution room safety monitoring system based on infrared sensing. In order to verify the beneficial effects of the present invention, scientific demonstrations are carried out through economic benefit calculations and simulation experiments , the data used in the embodiment of the present invention are ten sets of tests performed by the infrared sensor safety monitoring system of a power distribution room in a certain intelligent power distribution room in a distribution network in a certain area.

Specifically, as shown in the table below,

Among them, the algorithm of portrait feature contrast is to use the Euclidean distance of each portrait feature point, substitute it into the sigmoid function, and calculate its percentage;

In the formula, e is a natural constant, equal to 2.718281828459045, and x is the Euclidean distance;

Through the above formula to realize the calculation of the percentage, we only need to calculate the parameters to calculate the percentage.

Let's run in the verification set and record the maximum value x1 of the Euclidean distance. At this time, set a value corresponding to the maximum percentage of 99%, and then record the minimum value x2 of the Euclidean distance, and set the value corresponding to the minimum The percentage is 40%, and then substituting x1 and x2 into the above formula can calculate the values of α and β.

It is inferred from the experimental data that when the contrast ratio of portrait features is ≥85%, it is basically correct to judge as a new authorized person, and when the contrast ratio of portrait features is <85%, it is basically correct to judge as a new unauthorized person.

Among them, the No. 10 test was caused by the large gap between its current appearance and the information carrier of the uploaded personnel. After subsequent re-uploading and re-testing, the accuracy rate was correct.

Further, it can be seen that the accuracy rate has a great relationship with the image size, and the high-definition image processed by the infrared acquisition image has a higher accuracy rate (refer to Figure 7, Figure 8), thereby ensuring the accuracy of the portrait contrast rate and improve safety.

In addition, the data efficiency of the system is high, and the total amount of output data is small, generally a few bits. When the number of sensors is increased according to needs, the total output data of all sensors is usually tens of bits. The identification method greatly saves communication resources and computing resources.
