Embodiment 1

[0027] This embodiment discloses a smart monitoring method based on electric energy meters, such as figure 1 As shown, the method includes the following steps: S1. Obtain the total power of the outgoing line of the electric energy meter; in this step, various methods in the prior art can be used to collect the total power. Taking the household electric meter as an example, a household usually There is only one electric energy meter, and the electric power generated by all the electrical appliances in the household is the total power. A signal collector can be used to connect the electric energy meter to collect the total power of the electric appliances in the user's home. This is the prior art and will not be discussed here. To repeat, of course, other methods may also be used to collect the total power. This embodiment does not set any limitation on the method of obtaining the total power, and it is only used as an example for illustration.

[0028] S2. Determine whether the...

Embodiment 2

[0039] On the basis of Embodiment 1, this embodiment provides a more preferred technical solution. First, in the step of detecting the fluctuation range of the current total power, this embodiment adopts the following steps:

[0040] Collect total power every preset time interval;

[0041] Take continuous k total power data in time order to obtain the average power sample M (k is a positive integer greater than 1);

[0042] The total power data collected each time takes the average power sample M as the average value to obtain the standard deviation δ. The method of calculating standard deviation can be obtained according to the formula of standard deviation.

[0043] In this step, analyzing power fluctuations by means of calculating the standard deviation has better anti-interference performance.

[0044]As an alternative implementation manner, the preset power threshold is not less than 100W. The time threshold is not less than 24 hours. In this way, misjudgment caused b...

Embodiment 3

[0046] This embodiment provides an intelligent monitoring system based on electric energy meters, such as figure 2 As shown, it includes a current detection unit 1, a voltage detection unit 2, a processor 4 and a communication unit 3, the current detection unit 1, the voltage detection unit 2, and the communication unit 3 are respectively connected to the processor 4, Wherein the processor 4 is used to perform the following operations: collect the current and voltage information of the outgoing line of the electric energy meter every preset time interval and calculate the total power of the electric energy meter outgoing line, and take continuous k total power data in time order to calculate the average power sample M, calculate the fluctuation range of the total power according to each total power data and the average power sample M, when the fluctuation range of the total power is less than the preset fluctuation range threshold, timing, when the timing time exceeds the pres...

Abstract

The invention discloses an intelligent monitoring method and system based on an electric energy meter. The method comprises the following steps: S1, acquiring total power; S2, judging whether the current total power is greater than a preset power threshold value or not according to a preset power threshold value; S3, detecting a fluctuation amplitude of the current total power and comparing with apreset fluctuation amplitude threshold value, and if the fluctuation amplitude of the current total power is smaller than the preset fluctuation amplitude threshold value, entering a step S4; S4, calculating duration t of a state that the fluctuation amplitude of the current total power is smaller than the preset fluctuation amplitude threshold value; and S5, judging whether the time t is greaterthan a preset time threshold, and if so, making the electric energy meter trip. In the invention, an unattended state of a high-power electric appliance after the high-power electric appliance is continuously started for a certain time can be analyzed so that tripping operation is performed on the electric meter in time, power utilization safety of users and the society is ensured, and electric energy is saved.

Description

technical field [0001] The invention relates to the technical field of electric energy meters, in particular to an intelligent monitoring method and system based on electric energy meters. Background technique [0002] With the rapid development of the national economy, the increase in electricity sales year by year and the vigorous promotion of smart meters, the number of verification and installation of energy meters is increasing year by year. Although the current energy meters have been greatly improved compared with the previous generation, However, due to the huge user base, many electricity consumption behaviors that waste electric energy or even endanger public safety are still common. If you work for a long time without supervision, it will waste electricity at least, or cause a fire and endanger public safety. However, if it is possible to detect these electrical appliances that have been forgotten by the user to close and work for a long time and trip from the el...
