[0041] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0042] The power metering method, device, electronic device and storage medium of the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0043] Figure 1 is a schematic flowchart of the power metering method for a lamp provided by the present invention. This power metering method is applied to a cloud device or the lamp, that is, the execution subject of this power metering method is the lamp or the cloud device. As Figure 1 shown, this power metering method includes the following steps:

[0044] Step 100, obtaining the real-time working state of the lamp;

[0045] Step 110, obtaining the input power corresponding to the real-time working state according to the association information and the real-time working state. The association information is obtained based on a pre-measurement of the lamp, and the association information includes the correspondence between the working state of the lamp and the input power;

[0046] Step 120, outputting the input power. Specifically, the electric energy consumed by the lamp in different working states may not be the same, that is, the input power of the lamp in different working states may not be the same; in order to more conveniently present a more accurate input power to the user, the input power corresponding to each working state of the lamp can be pre-measured and saved. After the lamp is installed and used, the input power corresponding to the real-time working state of the lamp can be determined based on the real-time working state of the lamp and the input power of the lamp in different working states measured in advance, and used to present to the user.

[0047] Among them, pre-measuring and saving the input power corresponding to at least one working state of the lamp can be completed at the factory stage of the lamp.

[0048] Optionally, the association information may be a table information, for example, it may be the table information as shown in Table 1 below:

[0049] Table 1

[0050] Working state State A State B State C Input power a b c

[0051] Taking a lamp as an example, assume that the lamp has three usage states, namely bright state, warm state, and sleep state. The associated information can be the information in Table 2 below:

[0052] Table 2

[0053] Working state Bright state Warm state Sleep state Input power 100W 75W 50W

[0054] Optionally, the associated information can be a string of information representing the corresponding relationship, such as:

[0055] State A - a; State B - b; State C - c.

[0056] Taking a lamp as an example, assume that the lamp has three usage states, namely bright state, warm state, and sleep state. The associated information can include:

[0057] Bright state - 100W; Warm state - 75W; Sleep state - 50W.

[0058] The power measurement method provided by the present invention pre-measures and stores the input power corresponding to the lamp in at least one working state respectively. Then, the lamp or the cloud device only needs to determine the real-time working state, and the input power corresponding to the real-time working state can be directly obtained, realizing simplicity and accurate measurement.

[0059] In some optional embodiments, the power measurement method is applied to the lamp, the lamp has at least two working states, and the method for obtaining the associated information based on the pre-measurement of the lamp includes:

[0060] Switch the working state of the lamp, and measure the input power corresponding to the lamp in each working state through a power meter;

[0061] Generate the associated information based on each working state and the input power corresponding to each working state;

[0062] Store the associated information in the storage unit of the lamp.

[0063] Optionally, the associated information can be locally saved by the lamp, such as saved in the first storage unit of the lamp, such as a Near Field Communication (NFC) module; the wireless module of the lamp can determine the real-time working state, and the wireless module of the lamp can directly determine the input power corresponding to the real-time working state based on the associated information locally saved by the lamp.

[0064] Specifically, the associated information is generated by the lamp itself. Specifically, during the factory stage of the lamp or before the lamp is installed and used, a power meter is connected to one side of the lamp. Then, the lamp orderly changes the pulse width modulation (PWM), continuously adjusts its working state, and measures the input power of the lamp through the power meter in each working state until the input powers corresponding to all working states are measured. Thus, the associated information can be generated and stored in the first storage unit of the lamp, such as an NFC module.

[0065] Specifically, when the associated information is stored in the storage module of the lamp itself, the lamp can directly determine the input power corresponding to the real-time working state based on the associated information in the storage module and the real-time working state, and send the determined input power corresponding to the real-time working state to the cloud, which is output to the user by the cloud. For example, the cloud presents it to the user through a display device or an APP.

[0066] Figure 2 It is a schematic diagram of measuring the input power of the lamp provided by the present invention. As Figure 2 shown, during the factory stage of the lamp or before the lamp is installed and used, a power meter is connected to one side of the lamp. The circuit structure of the lamp may specifically include: an alternating current / direct current (AC / DC) driver for converting an alternating voltage into a direct voltage; a direct current / direct current (DC / DC) driver for converting a constant voltage into a constant current; a wireless module for controlling the DC / DC driver through pulse width modulation (PWM) to achieve dimming and color adjustment, that is, to adjust the working mode; an NFC for storing data. Specifically, during the measurement process of the input power, an automated test method is used to control the wireless module to enter an automated test program (the automated test program is a pre-written program for automatically measuring the input powers corresponding to the lamp in the at least one working state), orderly change the PWM to continuously adjust the working state of the lamp, export the test data, that is, the input power measured by the power meter, and burn it into the NFC.

[0067] The present invention uses NFC to store data, which is convenient for adjusting the stored data at any time.

[0068] In some optional embodiments, the power measurement method is applied to a cloud device, and the method for obtaining the associated information further includes: receiving the associated information sent by the lamp.

[0069] Optionally, the associated information can be saved by the cloud device;

[0070] Specifically, the association information is generated by the luminaire itself. Specifically, at the stage of the luminaire leaving the factory, or before the luminaire is installed and used, a power meter is connected to one side of the luminaire. The luminaire changes the PWM in an orderly manner, continuously adjusts its working state, and measures the input power of the luminaire through the power meter in each working state until the input power corresponding to all working states is measured. Then, the association information can be generated and sent to the cloud. The cloud receives the association information sent by the luminaire and stores the association information in the second storage unit.

[0071] As Figure 2 shown, at the stage of the luminaire leaving the factory, or before the luminaire is installed and used, a power meter is connected to one side of the luminaire. The circuit structure of the luminaire may specifically include: an AC-DC driver for converting an AC voltage into a DC voltage; a DC-DC driver for converting a constant voltage into a constant current; a wireless module for controlling the DC-DC driver through pulse width modulation (PWM) to achieve dimming and color adjustment, that is, to adjust the working mode; an NFC for storing data. Specifically, during the measurement of the input power, an automated test method is used to control the wireless module to enter an automated test program (the automated test program is a pre-written program for automatically measuring the input power corresponding to the luminaire in at least one working state). The PWM is changed in an orderly manner to continuously adjust the working state of the luminaire, and the test data, that is, the input power measured by the power meter, is exported and sent to the cloud for storage. The cloud receives the association information sent by the luminaire and stores the association information in the second storage unit.

[0072] In some alternative embodiments, when the power measurement method is applied to a cloud device, obtaining the real-time working state of the luminaire further includes: receiving the real-time working state sent by the luminaire.

[0073] Specifically, in the case where the association information is stored in the cloud device, the real-time working state can be directly determined by the luminaire and sent to the cloud device. After the cloud device receives the real-time working state sent by the luminaire, based on the stored association information and the real-time working state, the cloud device determines the input power corresponding to the real-time working state and then outputs it to the user. For example, it is presented to the user by the cloud through a display device or an APP.

[0074] In some alternative embodiments, when the power measurement method is applied to a cloud device, obtaining the real-time working state of the luminaire further includes: receiving the working state information sent by the luminaire, where the working state information is used to indicate the real-time working state of the luminaire; and determining the real-time working state of the luminaire based on the working state information.

[0075] Specifically, the real-time working state of the luminaire can be carried in the working state information and sent by the luminaire to the cloud device;

[0076] Specifically, when the associated information is stored in the cloud device, the lamp can directly determine the real-time working state, generate working state information and send it to the cloud device. After receiving the working state information sent by the lamp, the cloud device determines the real-time working state of the lamp based on the working state information, and based on the stored associated information and the real-time working state, determines the input power corresponding to the real-time working state, and then outputs it to the user, for example, presented to the user by the cloud through a display device or an APP.

[0077] In some alternative embodiments, the power measurement method is applied to the lamp, and further includes: receiving the input power sent by the cloud device.

[0078] Specifically, when the associated information is stored in the cloud device, the lamp can directly determine the real-time working state, generate working state information and send it to the cloud device. After receiving the working state information sent by the lamp, the cloud device determines the real-time working state of the lamp based on the working state information, and based on the stored associated information and the real-time working state, determines the input power corresponding to the real-time working state, and then sends it to the lamp. After receiving the input power sent by the cloud device, the lamp can be presented to the user through a display device or an APP.
