Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] A detection method for illegal use of a voltage-regulating socket in a student dormitory, the detection method comprising the following steps:

[0023] Step 1: With a sampling frequency of 12.8k / s, high-frequency sampling is performed on the current and voltage at the dormitory bus to obtain the current sampling sequence I of each power frequency cycle T ={i 1 , i 2 ,...,i n} T and voltage sampling sequence U T ={u 1 , u 2 ,...,u n} T , n represents the number of sampling points.

Abstract

The invention discloses a method for detecting illegal use of a voltage regulating socket in a student dormitory, and the method comprises the steps: 1, carrying out the high-frequency sampling of a current and a voltage at a dormitory bus at a certain sampling frequency, and obtaining a current sampling sequence and a voltage sampling sequence of each power frequency period; 2, calculating active power and reactive power of a corresponding power frequency period through the current sampling sequence and the voltage sampling sequence; 3, sampling active power and reactive power of the current line once per second to form an active power queue and a reactive power queue; 4, setting a power counter C=0, and when P<x+1> is greater than Px and Q<x+1> is greater than Qx, setting the power counter C=C+1; 5, judging that the power counter C is greater than or equal to 5, if so, judging that a voltage regulating socket is connected into the dormitory and runs, otherwise, executing step 6; 6, judging whether R is greater than a preset threshold value, if so, judging that the voltage regulating socket is connected into the dormitory and runs, otherwise, executing the step 1. The method provided by the invention can effectively solve the electrical potential safety hazard that the students bypass the power limiting system by means of the dormitory voltage regulating socket.

Description

technical field [0001] The invention belongs to the field of electric appliance detection, and in particular relates to a detection method for illegally using a voltage-regulating socket in a student dormitory. Background technique [0002] Nowadays, the dormitories of many schools are equipped with limited power systems to monitor the power consumption of electrical appliances connected to the dormitories. When it is detected that the power of the connected electrical appliances exceeds the set threshold, the power supply is cut off to prevent students from using prohibited electrical appliances to cause electrical fires. However, in recent years, there have been many dormitory-specific voltage-regulating sockets to escape the dormitory power rationing system. [0003] Dormitory voltage-regulating sockets can be easily purchased on major e-commerce platforms. Most of them are cheap, but the quality is poor; usually after a period of operation, there will be an obvious burn...
