[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 2023118190014, filed on December 26, 2023, entitled “Power metering method and system for lamps, lamps, cloud devices and electronic devices,” which is incorporated herein by reference in its entirety. Technical Field

[0004] With the development of Internet of Things technology, smart homes have also developed rapidly. More and more smart home systems and smart home products have been popularized. Energy saving and environmental protection of smart home products are also aspects that users are more concerned about. In order to allow users to clearly understand the power consumption of lamps, power detection functions can be added to lamps and presented to users in digital form.

[0005] However, in the related art, when measuring the input power of the lamp, a metering chip is used to directly detect the input current, input voltage and phase angle, which can accurately calculate the input effective power. However, the metering chip is expensive, and since the metering chip is at the primary level of the lamp circuit structure and the wireless module is at the secondary level of the lamp circuit structure, an isolation device needs to be added to transmit the metering information to the wireless module. The architecture is cumbersome and complex and not conducive to miniaturization design. If the output power is calculated by detecting the output voltage and output current of the lamp, and the input power is reversed by the preset conversion efficiency, it will lead to a large error in the input power detection.

[0044] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0045] The power metering method, device, electronic device, and storage medium according to the embodiments of the present application are described below with reference to the accompanying drawings.

[0046] FIG1 is a flow chart of a method for measuring the power of a lamp provided in an embodiment of the present application. The method is applied to a cloud device or the lamp, that is, the lamp or the cloud device is the executing entity of the method. As shown in FIG1 , the method includes the following steps:

[0047] Step 100, obtaining the real-time working status of the lamp;

[0048] Step 110: Acquire input power corresponding to the real-time working state based on correlation information and the real-time working state, wherein the correlation information is obtained based on pre-measurement of the lamp and includes a correspondence between the working state of the lamp and the input power;

[0049] Step 120: Output the input power. Specifically, the electrical energy consumed by the lamp in different operating states may not be the same, that is, the input power of the lamp in different operating states may not be the same. To more conveniently present a more accurate input power to the user, the input power corresponding to each operating state of the lamp can be pre-measured and stored. After the lamp is installed and used, the input power corresponding to the real-time operating state of the lamp can be determined based on the real-time operating state of the lamp and the pre-measured input power of the lamp in different operating states, and presented to the user.

[0050] The pre-measuring and storing of the input power corresponding to the lamp in at least one working state may be completed when the lamp leaves the factory.

[0051] Optionally, the association information may be a table information, for example, the table information may be the following Table 1:

[0052] Table 1

[0053] Taking a lamp as an example, assuming 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:

[0054] Table 2

[0055] Optionally, the association information may be a string of information indicating a corresponding relationship, such as:

[0056] A state - a; B state - b; C state - c.

[0057] Taking a lamp as an example, assuming that the lamp has three usage states: bright state, warm state, and sleep state, the associated information may include:

[0058] Bright mode - 100W; Warm mode - 75W; Sleep mode - 50W.

[0059] The power metering method provided in this application pre-measures and stores the input power corresponding to the lamp in at least one working state. Then the lamp or cloud device only needs to determine the real-time working state to directly obtain the input power corresponding to the real-time working state, which is simple and accurate.

[0060] In some optional embodiments, the power metering method is applied to the lamp, the lamp has at least two operating states, and the method of obtaining the associated information based on pre-measurement of the lamp includes:

[0061] Switching the working state of the lamp, and measuring the input power corresponding to each working state of the lamp by a power meter;

[0062] generating the associated information based on each of the working states and the input power corresponding to each of the working states;

[0063] The associated information is stored in a storage unit of the lamp.

[0064] Optionally, the associated information can be stored locally by the lamp, such as in a first storage unit of the lamp, such as a near field communication (NFC) module; the real-time working status can be determined by the wireless module of the lamp, and the wireless module of the lamp can directly determine the input power corresponding to the real-time working status based on the associated information stored locally by the lamp.

[0065] Specifically, the associated information is generated by the lamp itself. Specifically, a power meter can be connected to one side of the lamp at the factory stage or before the lamp is installed and used. The lamp then sequentially changes pulse width modulation (PWM) to continuously adjust its working state. The power meter measures the input power of the lamp in each working state until the input power corresponding to all working states is measured. This generates the associated information and stores it in the first storage unit of the lamp, such as an NFC module.

[0066] Specifically, when the associated information is stored in the storage module of the lamp itself, the lamp itself can directly determine the input power corresponding to the real-time working status based on the associated information of the storage module and the real-time working status, and send the determined input power corresponding to the real-time working status to the cloud, which outputs it to the user from the cloud, for example, presenting it to the user through a display device or APP from the cloud.

[0067] FIG2 is a schematic diagram of measuring the input power of a lamp provided in an embodiment of the present application. As shown in FIG2 , a power meter is connected to one side of the lamp before the lamp leaves the factory or is installed and used. The circuit structure of the lamp may specifically include: an alternating current / direct current (ACDC) driver for converting AC voltage into DC voltage; a direct current / direct current (DCDC) driver for converting constant voltage into constant current; a wireless module for controlling the DCDC driver through pulse width modulation (PWM) to achieve dimming and color adjustment, that is, to adjust the operating mode; and NFC for storing data. Specifically, during the input power measurement process, an automated testing 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 lamp in at least one of the aforementioned operating states). The PWM is varied in an orderly manner to continuously adjust the operating state of the lamp. The test data, i.e., the input power measured by the power meter, is derived and burned into the NFC.

[0068] This application uses NFC to store data, making it convenient to adjust the stored data at any time.

The cloud receives the associated information sent by the lamp and saves the associated information in the second storage unit.

[0073] In some optional embodiments, the power metering method is applied to a cloud device, and obtaining the real-time working status of the lamp further includes: receiving the real-time working status sent by the lamp.

[0074] Specifically, when the associated information is stored in the cloud device, the real-time working status can be directly determined by the lamp and sent to the cloud device. After the cloud device receives the real-time working status sent by the lamp, the cloud device determines the input power corresponding to the real-time working status based on the stored associated information and the real-time working status, and then outputs it to the user, for example, it is presented to the user by the cloud through a display device or APP.
