Embodiment 1

[0034] Such as figure 1 Shown is a flow chart of an invented method for measuring and calculating the standby power of electrical equipment. The specific steps are as follows:

[0035] (1) Collect the current power value of the electrical equipment at the set collection time interval

[0036] In this embodiment, the air conditioner will be used as a typical electrical equipment for related descriptions, such as figure 2 Shown is a graph of the power change from the time an air conditioner is powered on to when it is turned on.

[0037] The current power value of the air conditioner is collected by the power collection device at a set collection time interval. The collection time interval can be set manually, for example, 0.1s or 0.05s. However, the smaller the interval, the more accurate the final calculated value. This implementation Example 1 takes 0.1s as an example.

[0038] Select 10 consecutive collection points in the collection time axis as a collection window period, and put...

Embodiment 2

[0055] Such as image 3 As shown, it is a flow chart of another method for measuring and calculating the standby power of electric equipment according to the present invention, which specifically includes the following steps:

[0056] (1) Collect the current power value of the electrical equipment at the set collection time interval, and continuously take n (n is a natural number greater than or equal to 3) window period values ​​in the collection time axis. In this embodiment 2, n takes 3 ;

[0057] This embodiment 2, such as Figure 4 Shown is a graph of the power change of an air conditioner from running to standby.

[0058] The current power value of the air conditioner is collected by the power collection device at a set collection interval. The collection time interval can be set manually, for example, 0.1s or 0.05s. However, the smaller the interval, the more accurate the final calculated value. This embodiment 2Take 0.1s as an example.

[0059] Select 10 continuous acquisiti...

Abstract

The invention provides a standby power calculating method for power consumption equipment, which belongs to the field of calculation. The current power of the power consumption equipment is acquired through setting a time interval, and an acquiring window period is set. When a power jump is determined, an accurate standby power is obtained through checking the power of the window period, and finally the standby power of the power consumption equipment is obtained through calculation. The standby power calculating method can satisfy a requirement for calculating the standby powers of different types of power consumption equipment, and overcomes a problem of incapability of accurately calculating the standby power because of low power factor of the power consumption equipment on the standby condition. A relatively accurate standby power can be obtained.

Description

Technical field [0001] The invention relates to the field of measurement and calculation, in particular to a method for measuring and calculating the standby power of electric equipment. Background technique [0002] With the development of the times, there are more and more types of electrical equipment in modern homes, and residents' electricity consumption is getting higher and higher. Many users have no habit of cutting off the power when they are not using electrical appliances, resulting in a lot of standby power being wasted every year. Many people are beginning to pay attention to whether there is hidden power consumption in household appliances, and there is an urgent need for standby power consumption detection of electrical equipment. General households use power testers to test, but the current power is tested, which cannot reflect the actual results normally. Summary of the invention [0003] In view of the shortcomings of the prior art, the present invention provide...
