Description
Technical Field

[0002] Understanding the actual power consumption of household appliances can help users save energy, reduce electricity bills and optimize usage habits, so as to control and reduce unnecessary power consumption. Generally speaking, the power consumption of household appliances is detected under standard working conditions. Taking a refrigerator as an example, the standard working conditions include elements such as stable physical environment, stable electrical environment and stable environmental humidity. However, there is a large gap between the actual power consumption of household appliances and the power consumption under standard working conditions, and the power consumption under standard working conditions cannot represent the actual power consumption.
[0003] With the development of artificial intelligence, to solve this problem, in the prior art, a monitoring model based on deep learning is used to monitor the actual power consumption of household appliances. Since the monitoring model requires high computing power, the monitoring model is usually deployed on a cloud server, and the operating parameters are uploaded to the cloud server by using the wireless communication function of household appliances. After receiving the operating parameters, the cloud server calls the monitoring model to calculate the actual power consumption of household appliances.
[0004] However, household appliances are usually connected to a cloud server through a router or a gateway. If the router or the gateway has a temporary failure or is disconnected due to the user's active operation, since the operating parameters during the network disconnection cannot be uploaded to the cloud server, resulting in data loss, it will cause a large deviation in the calculation result of the actual power consumption of household appliances.

[0043] As Figure 1 、 Figure 7 and Figure 8 shown, one or more embodiments of the present application provide a power consumption detection device 10. The power consumption detection device 10 is provided independently of the controller 202 in the household appliance 20. The power consumption detection device 10 includes a communication module 101, a processing chip 102, and a storage module 103.
[0044] In one or more embodiments of the present application, the communication module 101 includes a PCB antenna. The communication module 101 is communicatively connected to the cloud server 30. The processing chip 102 is communicatively connected to the communication module 101. The storage module 103 is communicatively connected to the processing chip 102. The processing chip 102 is also communicatively connected to the controller 202, and the controller 202 is disposed in the household appliance 20 to control the operation of the household appliance 20. The controller 202 is configured to transmit the operation parameters of the household appliance 20 to the processing chip 102 and store them in the storage module 103.
[0045] More specifically, the controller 202 is communicatively connected to the load 204 and the sensing module 203 in the household appliance 20. The controller 202 is used to control the operation of the load 204 and collect status data through the sensing module 203. Taking a refrigerator as an example, the status data collected by the sensing module 203 includes ambient temperature, ambient humidity, temperature of the refrigerator compartment, compressor speed (frequency), fan speed, defrost status of the refrigerator, compressor status, etc. The controller 202 generates operation parameters based on the status data to control the load 204 therein, such as a compressor, a fan, a defrost heating element, etc., so that they operate to meet the requirements of the set parameters. The method by which the controller 202 collects status data and generates operation parameters to control the operation of the household appliance 20 is an algorithm disclosed in the prior art and is not the focus of protection of the present utility model. In the prior art, the controller 202 uploads the operation parameters to the cloud server 30, and the cloud server 30 further generates the actual power consumption; this may result in data loss during a network disconnection.
[0046] In the present application, on the basis of the original controller 202, a redundant power consumption detection device 10 independent of the controller is provided. The processing chip 102 in the detection device is directly communicatively connected to the controller 202, continuously obtains the operation parameters of the household appliance 20, and stores the obtained operation parameters of the household appliance 20 in the local storage module 103. In this way, even if the network is temporarily interrupted, the data integrity during the interruption can be ensured. For the cloud server 30, the operation parameters during the temporary network interruption can still be obtained, which will not affect the calculation of the actual power consumption and can avoid the degradation of the generalization ability caused by the model's inability to fully learn the data distribution.
[0047] In addition, the power consumption detection device 10 provided in the present application can also be matched with traditional non-smart household appliances to expand the function of monitoring the actual power consumption.
[0048] Such as Figure 9As shown, in one or more embodiments of the present application, the power consumption detection device 10 may be disposed in an independent housing. The power consumption detection device 10 further includes a display 104. When matching with traditional non-smart household appliances, the power consumption detection device 10 may also display the real-time power consumption. The display 104 may be an LCD or an LED display 104, which may display a human-machine interaction interface or a Web interface.
[0049] In one or more embodiments of the present application, the cloud server 30 is communicatively connected to the mobile terminal 40. The mobile terminal 40 includes, but is not limited to, one or more of a laptop computer, a tablet computer, a smart phone, a wearable device, a handheld mobile device, and a vehicle-mounted device.
[0050] Refer to Figures 1 to 6 , and the specific circuit design of the power consumption detection device 10 will be introduced.
[0051] In one or more embodiments of the present application, the PCB antenna PCB_ANT in the communication module 101 refers to an on-board PCB antenna PCB_ANT integrated on a printed circuit board, which is used for transmitting and receiving wireless signals between the communication module 101 and the cloud server 30. The size and shape of the PCB antenna PCB_ANT may be designed according to the operating frequency. Exemplarily, the PCB antenna PCB_ANT may be a ceramic patch antenna.
[0052] In one or more embodiments of the present application, the communication module 101 includes a resonant circuit. The resonant circuit includes a first inductor L3 and a first capacitor C5. The first end of the first inductor L3 is electrically connected to the feeding end of the PCB antenna PCB_ANT, the positive electrode of the first capacitor C5 is electrically connected to the second end of the first inductor L3, and the negative electrode of the first capacitor C5 is grounded. The grounding end of the PCB antenna PCB_ANT is grounded. The resonant circuit is used to adjust the impedance matching of the PCB antenna PCB_ANT. By adjusting the inductance value and capacitance value of the first inductor L3, the resonant spectrum is changed, so that the PCB antenna PCB_ANT operates in the required frequency band.
[0053] In one or more embodiments of the present application, the matching impedance of the communication module 101 is 50 ohms.
[0054] In one or more embodiments of the present application, the communication module 101 further includes a filtering circuit. The filtering circuit includes a second capacitor C11, a second inductor L2, and a third capacitor C12. The positive electrode of the second capacitor C11 is electrically connected to the first end of the first inductor L3 and the feeding end of the PCB antenna PCB_ANT. The first end of the second inductor L2 is electrically connected to the positive electrode of the second capacitor C11. The positive electrode of the third capacitor C12 is electrically connected to the second end of the second inductor L2 in one path and to the input pin LNA_IN of the low-noise amplifier of the processing chip 102 in another path. The low-noise amplifier can further enhance the receiving performance of wireless communication, improve the receiving sensitivity and signal quality of the signal, and minimize the noise interference of the signal during transmission. The impedance of the input pin LNA_IN of the low-noise amplifier is matched with the impedance of the PCB antenna PCB_ANT to avoid signal reflection and loss.
[0055] The second capacitor C11, the second inductor L2, and the third capacitor C12 form a PI-type filtering circuit, and the filtering circuit can filter out noise and further adjust the impedance of the signal to optimize the transmission of wireless signals.
[0056] In one or more embodiments of the present application, the power consumption detection device 10 further includes a clock module. The clock module includes a crystal oscillator chip Y1. The crystal oscillator chip Y1 includes a crystal oscillator chip input terminal XIN and a crystal oscillator chip output terminal XOUT.

[0057] In one or more embodiments of the present application, a fourth capacitor C1 is provided at the crystal oscillator chip input terminal XIN. The positive electrode of the fourth capacitor C1 is electrically connected to the crystal oscillator chip input terminal XIN, and the negative electrode is grounded. A fifth capacitor C4 is provided at the crystal oscillator chip output terminal XOUT. The positive electrode of the fifth capacitor C4 is electrically connected to the crystal oscillator chip output terminal XOUT, and the negative electrode is grounded. The fourth capacitor C1 and the fifth capacitor C4 form an external crystal oscillator circuit for generating an accurate clock frequency signal.
[0058] The processing chip 102 applies a power supply voltage to the crystal oscillator chip input terminal XIN of the crystal oscillator chip Y1, and the crystal starts to oscillate, generating a stable clock frequency signal. The clock frequency signal is amplified by an amplifier and fed back to the input terminal of the crystal. Due to the piezoelectric effect of the crystal, the feedback signal causes the crystal to generate mechanical vibration. This mechanical vibration generates charge again, forming a new electrical signal. This new electrical signal is amplified and fed back to the crystal, forming a stable oscillation cycle. In this way, the external crystal oscillator circuit can generate a very stable frequency signal, which is input to the processing chip 102 through the crystal oscillator chip output terminal XOUT of the crystal oscillator chip Y1 for generating the clock signal of the processing chip 102.
[0059] Since the power consumption detection device 10 is configured to temporarily store operation parameters when the network is interrupted, the clock module of the processing chip 102 provides a stable and accurate clock signal, which can ensure the consistency and integrity of data during communication with the controller 202 and reduce potential faults related to timing.

[0069] In one or more embodiments of the present application, the write protection terminal / WP is configured to be active low. When the write protection terminal / WP receives a low-level signal, the write operation is prohibited to protect the data of the flash chip U2 from being accidentally rewritten.
