[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0027] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] The present application embodiment provides a portable electric energy metering device. Figure 1 , which is a structural diagram of a portable electric energy metering device according to an embodiment of the present application.

[0029] In an embodiment of the present application, the portable electric energy metering device 1 includes: a control module 11, a metering socket 12, a metering plug 13, a metering module 14 and a display module 15 respectively connected to the control module 11, and the metering module 14, the metering socket 12 and the metering plug 13 are connected to each other.

[0030] The metering socket 12 is used to connect the power plug of the load to be measured, and the metering plug 13 is used to connect the power socket of the power supply. The metering socket 12 and the metering plug 13 connect or disconnect the load to be measured and the power supply under the control of the control module 11.

[0031] The metering module 14 is used to detect the electric energy parameters corresponding to the measured load under the control of the control module 11 and send the electric energy parameters to the control module 11 .

[0032] The control module 11 determines the power usage data corresponding to the measured load according to the power parameters, and sends the power usage data to the display module 15 for display.

[0033] Furthermore, the measured load refers to the load for which the power usage data needs to be measured. The types of measured loads include but are not limited to: Internet of Things devices. For example: air conditioners, televisions, refrigerators, etc.

[0034] Furthermore, the metering socket 12 can be a five-point socket. The metering plug 13 can be a wired plug. Both the metering socket 12 and the metering plug 13 comply with the new national standard. The power plug of the load under test can be changed from being inserted into the power socket to being inserted into the metering socket 12, thereby connecting the portable electric energy metering device 1 to the front end of the load under test. The metering plug 13 is inserted into the power socket, thereby connecting the portable electric energy metering device 1 in series between the power supply and the load under test, so that the power supply can normally supply power to the load under test. Figure 2 , which is a schematic diagram of the appearance of a portable electric energy metering device 1 according to an embodiment of the present application.

[0035] Furthermore, the electric energy parameter is a detection value of the metering module 14. The electric energy parameter includes but is not limited to: current and voltage.

[0036] Furthermore, the power usage data at least includes: the power used by the measured load. The control module 11 needs to measure the power usage time. Power used (kWh) = power (kW) × power usage time (h). Power used (degrees) = power (W) × power usage time (h) / 1000. Power = voltage × current.

[0037] In the embodiment of the present application, the portable electric energy metering device 1 may further include: a communication module 16 connected to the control module 11. Figure 3 , which is a structural diagram of a portable electric energy metering device 1 according to another embodiment of the present application.

[0038] The communication module 16 is used to receive control instructions sent by a preset intermediate device and send the control instructions to the control module 11. The intermediate device may be a control device in a local area network or a designated Internet of Things device. For example, the intermediate device may be a smart assistant device in a smart home system.

[0039] Furthermore, types of control instructions include, but are not limited to: connection instructions, disconnection instructions, detection instructions, and reporting instructions.

[0040] The connection instruction is used to instruct the metering socket 12 to connect to the power plug, and the metering plug 13 to connect to the power socket. In this way, the electric energy of the power supply can reach the load under test through the power socket, the metering plug 13, the metering socket 12, and the power plug, so as to supply power to the load under test.

[0041] The disconnection instruction is used to instruct the metering socket 12 to disconnect the power plug, and the metering plug 13 to disconnect the power socket. In this way, the electric energy of the power supply cannot reach the metering plug 13 through the power socket, and then the electric energy cannot reach the load to be measured, and the load to be measured cannot be powered.

[0042] The detection instruction is used to instruct the metering module 14 to start detecting the electric energy parameters corresponding to the measured load.

[0043] The reporting instruction is used to instruct the control module 11 to report the power usage data of the measured load to the intermediate device, or the reporting instruction is used to instruct the control module 11 to report the power usage data of the measured load to the user terminal through the intermediate device.

[0044] When the control instruction is a connection instruction, the control module 11 controls the metering socket 12 and the metering plug 13 to connect the measured load and the power supply. Furthermore, in the embodiment of the present application, a switch mechanism can be set in the metering socket 12 and the metering plug 13. The switch structure can connect the passage or disconnect the passage. After the metering socket 12 is inserted into the power plug of the measured load, and the metering plug 13 is inserted into the power socket, only a line connection relationship is generated between the metering socket 12 and the power plug, and a line connection relationship is generated between the metering plug 13 and the power socket. However, when the switch mechanisms in the metering socket 12 and the metering plug 13 are not closed, the line connection relationship cannot generate a passage, so the power supply cannot supply power to the measured load.

[0045] When the control instruction is a disconnection instruction, the control module 11 controls the metering socket 12 and the metering plug 13 to disconnect the measured load and the power supply.

[0046] When the control instruction is a detection instruction, the control module 11 controls the metering module 14 to start detecting the electric energy parameters corresponding to the measured load. Of course, the type of control instruction may also include a stop detection instruction. When the control instruction is a stop detection instruction, the control module 11 controls the metering module 14 to stop detecting the electric energy parameters corresponding to the measured load.

[0047] When the control instruction is a reporting instruction, the control module 11 sends the power usage data to the intermediate device through the communication module 16. Although the control module 11 sends the power usage data to the intermediate device through the communication module 16, the destination of the power usage data is not limited to the intermediate device.

[0048] In the embodiment of the present application, the control instruction can be triggered on the portable energy metering device 1. For example, buttons corresponding to the connection instruction, disconnection instruction, detection instruction and reporting instruction are set on the portable energy metering device 1. Clicking the corresponding button can issue the corresponding control instruction. The types of buttons include: virtual buttons displayed in the display module 15 and physical buttons set on the portable energy metering device 1.

[0049] In the embodiment of the present application, since the portable electric energy metering device 1 may further include a communication module 16 , it may also receive control instructions from an external device.

[0050] Specifically, the communication module 16 is used to receive control instructions collected by the intermediate device, or receive control instructions sent by a preset user terminal through the intermediate device, or receive control instructions sent by the user terminal through a preset cloud server, a preset communication device and an intermediate device. The types of user terminals include but are not limited to: mobile phones, tablet computers and personal computers.

[0051] Correspondingly, when the control instruction is a reporting instruction, the control module 11 sends the power usage data to the intermediate device so that the intermediate device plays the power usage data by voice; or, when the control instruction is a reporting instruction, the control module 11 sends the power usage data to a preset user terminal through the intermediate device, or sends the power usage data to the user terminal through the intermediate device, the preset communication device and the preset cloud server, so that the user terminal displays the power usage data.

[0052] In the embodiment of the present application, the portable electric energy metering device 1 includes: a control module 11, a metering socket 12, a metering plug 13, a metering module 14 and a display module 15 connected to the control module 11 respectively, and the metering module 14, the metering socket 12 and the metering plug 13 are connected to each other; the metering socket 12 is used to connect the power plug of the load to be measured, and the metering plug 13 is used to connect the power socket of the power supply, and the metering socket 12 and the metering plug 13 are connected or disconnected from the load to be measured and the power supply under the control of the control module 11; the metering module 14 is used to detect the electric energy parameters corresponding to the load to be measured under the control of the control module 11 and send the electric energy parameters to the control module 11; the control module 11 determines the electric energy usage data corresponding to the load to be measured according to the electric energy parameters, and sends the electric energy usage data to the display module 15 for display. In the embodiment of the present application, the portable electric energy metering device 1 is connected in series between the power supply and the load to be measured through the metering socket 12 and the metering plug 13, and other loads in the environment where the load to be measured are located can operate normally. The portable electric energy metering device 1 can be used to measure the electric energy usage data of the load to be measured separately, which is simple and easy to use. After adding the communication module 16 to the portable power metering device 1, the portable power metering device 1 can be remotely controlled, and the user can interact with the portable power metering device 1 through an intermediate device. For example, voice control instructions can be sent to the portable power metering device 1, and the power usage information of the device under test can be played through the intermediate device.

[0053] In the embodiment of the present application, the metering module 14 can adopt an electric meter metering chip. The electric meter metering chip has a clock calibration-free function, integrates 2-way high-precision Sigma-Delta ADC, reference voltage, power management and other analog circuit modules, and digital signal processing circuits for processing active power, current and voltage effective values ​​and other electrical parameters, can measure current, voltage effective value, active power, active electric energy and other parameters, can output fast current effective value (for overcurrent protection), and waveform output and other functions, output data through the UART / SPI interface, and can collect data through the main control MCU (Microcontroller Unit).

[0054] In the embodiment of the present application, the communication module 16 may be a Bluetooth module. For example, the Bluetooth module complies with the Bluetooth version 5.0 specification, the transmission speed is 4 times that of Bluetooth 4.2, the effective transmission distance is 4 times that of Bluetooth 4.2, the Bluetooth module embedded 512KB flash memory allows customized software development, and the Bluetooth module uses a serial port to interact with the control module 11.

[0055] In the embodiment of the present application, the control module 11 can use a low-power main control chip. The control module 11 can connect the communication module 16 and the metering module 14 through two UART serial ports, read the various power parameters output by the metering module 14 in real time and perform processing and calculation to obtain the power usage data corresponding to the measured load. Whenever the control module 11 receives a reporting instruction transmitted from the intermediate device, it returns the power usage data to the intermediate device through the communication module 16.

[0056] In the embodiment of the present application, the display module 15 is connected to the control module 11 via an IIC bus, and the display module 15 may adopt an OLED display screen to achieve low power consumption display.

[0057] Based on the portable power metering device 1, the embodiment of the present application provides a portable power metering system. Based on the portable power metering system, the receiving path of the control instruction and the reporting path of the power usage data can also be better understood. Figure 4 FIG. 1 is a schematic diagram of a portable electric energy metering system according to an embodiment of the present application.

[0058] In an embodiment of the present application, the portable power metering system includes: an intermediate device 2, a portable power metering device 1, a communication device 3 and a user terminal 4 respectively connected to the intermediate device 2, a cloud server 5 connected to the communication device 3, and a load to be measured connected in series between a power source and the portable power metering device 1.

[0059] The types of communication devices 3 include, but are not limited to: home gateways and routers.

[0060] The intermediate device 2 collects control instructions or receives control instructions from the user terminal 4. Further, the intermediate device 2 collects control instructions, including: the intermediate device 2 collects control instructions input by the user through voice. The control instructions from the user terminal 4 include: control instructions sent by the user terminal 4 to the intermediate device 2, or sent by the user terminal 4 to the intermediate device 2 through the cloud server 5 and the communication device 3.

[0061] For example, when a user is at home, he / she hopes to see the power usage data of the measured load at home on the mobile phone. Then, the user can click the button corresponding to the reporting instruction to be issued on the mobile phone, and send the reporting instruction corresponding to the button to the intermediate device 2.

[0062] For another example: when a user is not at home, he wants to see the power usage data of the measured load at home on his mobile phone. Then the user can click the button corresponding to the reporting instruction to be issued on the mobile phone, and send the reporting instruction corresponding to the button to the cloud server 5 through the data network, and the cloud server 5 sends it to the communication device 3, and then the communication device 3 sends the reporting instruction to the intermediate device 2.

[0063] The intermediate device 2 sends the control instruction to the portable power metering device 1, so that the portable power metering device 1 executes the control instruction. Further, the types of control instructions include but are not limited to: connection instructions, disconnection instructions, detection instructions and reporting instructions.

[0064] When the control instruction is a connection instruction, the control module 11 controls the metering socket 12 and the metering plug 13 to connect the measured load and the power supply.

[0065] When the control instruction is a disconnection instruction, the control module 11 controls the metering socket 12 and the metering plug 13 to disconnect the measured load and the power supply.

[0066] When the control instruction is a detection instruction, the control module 11 controls the metering module 14 to start detecting the electric energy parameters corresponding to the measured load.

[0067] When the control instruction is a reporting instruction, the control module 11 sends the power usage data to the intermediate device 2 through the communication module 16 .

[0068] In the case where the control instruction is a reporting instruction, if the reporting instruction is collected by the intermediate device 2, the control module 11 sends the power usage data to the intermediate device 2 so that the intermediate device 2 can play the power usage data by voice.

[0069] In the case where the control instruction is a reporting instruction, if the reporting instruction is sent by the user terminal 4 to the intermediate device 2 , the control module 11 sends the power usage data to the user terminal 4 through the intermediate device 2 .

[0070] In the case where the control instruction is a reporting instruction, if the reporting instruction is sent by the user terminal 4 to the intermediate device 2 through the cloud server 5 and the communication device 3, the control module 11 sends the power usage data to the user terminal 4 through the intermediate device 2, the communication device 3 and the cloud server 5, so that the user terminal 4 displays the power usage data.

[0071] The embodiment of the present application proposes a portable electric energy metering device 1. If the power consumption of a load needs to be measured, the portable electric energy metering device 1 only needs to be connected in series to the front stage of the load. The portable electric energy metering device 1 is equipped with a metering plug 13 and a metering socket 12 for convenient access to the power grid. The portable electric energy metering device 1 has a communication module 16, which can interact with the intermediate device 2, and can inquire about the power consumption of the load to be measured by voice, and quickly disconnect the power consumption of the load to be measured by voice. Of course, the portable electric energy metering device 1 can also be remotely controlled through the user terminal 4, which is convenient for users to use and view the power consumption of the load to be measured, and can be highly real-time.

[0072] Based on the portable power metering device, the embodiment of the present application also provides a portable power metering method. The execution subject of the portable power metering method is the above-mentioned control module. Figure 5 FIG. 1 is a flow chart of a portable electric energy metering method according to an embodiment of the present application.

[0073] Step S510: connecting or disconnecting the load to be measured and the power supply by controlling the metering socket and the metering plug.

[0074] Since the metering socket is connected to the power plug of the load under test, and the metering plug is connected to the power socket of the power supply, the load under test and the power supply can be connected or disconnected by controlling the metering socket and the metering plug.

[0075] Specifically, a control instruction sent by a preset intermediate device is received, wherein the control instruction collected by the intermediate device is received, or the control instruction sent by a preset user terminal through the intermediate device is received, or the control instruction sent by the user terminal through a preset cloud server, a preset communication device and the intermediate device is received.

[0076] The types of control instructions include: the connection instruction, the disconnection instruction, the detection instruction and the reporting instruction.

[0077] Furthermore, after receiving a connection instruction sent by the intermediate device, the metering socket and the metering plug can be controlled to connect the load under test and the power supply; after receiving a disconnection instruction sent by the intermediate device, the metering socket and the metering plug can be controlled to disconnect the load under test and the power supply.

[0078] Step S520: When the load under test and the power supply are connected, the metering module is controlled to detect the electric energy parameters corresponding to the load under test.

[0079] When the load under test and the power supply are connected, the power supply can normally supply power to the load under test, and the load under test can work normally. At this time, the metering module can detect the corresponding electric energy parameters under test. The types of electric energy parameters include but are not limited to: current, voltage effective value, active power, and active electric energy.

[0080] Specifically, when the load under test and the power supply are connected, after receiving the detection instruction sent by the intermediate device, the metering module is controlled to detect the electric energy parameters corresponding to the load under test.

[0081] Step S530, receiving the electric energy parameters detected by the metering module and determining the electric energy usage data corresponding to the measured load according to the electric energy parameters.

[0082] The power usage data includes at least the power used by the measured load.

[0083] Specifically, after determining the power usage data corresponding to the measured load according to the power parameters, the power usage data corresponding to the measured load can be sent to the intermediate device through the communication module after receiving the reporting instruction sent by the intermediate device.

[0084] Furthermore, the power usage data is sent to the intermediate device so that the intermediate device plays the power usage data by voice; or, the power usage data is sent to the intermediate device, and the power usage data is sent to a preset user terminal through the intermediate device, or, the power usage data is sent to a preset user terminal through the intermediate device, a preset communication device and a preset cloud server, so that the user terminal displays the power usage data.

[0085] Step S540: sending the power usage data corresponding to the measured load to a display module for display.

[0086] The control module sends the power usage data to the display module, and the display module displays the power usage data.

[0087] In an embodiment of the present application, the control module connects or disconnects the load to be measured and the power supply by controlling the metering socket and the metering plug; when the load to be measured and the power supply are connected, the control module detects the electric energy parameters corresponding to the load to be measured; receives the electric energy parameters detected by the metering module and determines the electric energy usage data corresponding to the load to be measured according to the electric energy parameters; and sends the electric energy usage data corresponding to the load to be measured to the display module for display. The embodiment of the present application utilizes the metering socket and the metering plug to connect the portable electric energy metering device in series at the front end of the load to be measured, utilizes the metering module to detect the electric energy parameters of the load to be measured, utilizes the control module to determine the electric energy usage data according to the electric energy parameters, and utilizes the display device to display the electric energy usage data, thereby realizing the metering of the electric energy usage of a load to be measured, and is convenient to operate without affecting the normal operation of other loads.

[0088] The present application also provides a portable electric energy metering device. Figure 6 , which is a structural diagram of a portable electric energy metering device according to an embodiment of the present application.
