[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In one aspect, this utility model provides a smart power cord. Figure 1 This is a schematic diagram of the structure of a smart power cord provided in an embodiment of the present utility model.

[0027] like Figure 1As shown, the smart power cord includes a housing 10; the housing 10 is equipped with a power acquisition module and a communication module for collecting and transmitting power information; one end of the housing 10 is connected to an appliance plug 20, and the other end of the housing 10 is connected to a power input plug 30.

[0028] Specifically, the housing 10 can take various shapes, such as square or round. The housing 10 integrates a power acquisition module and a communication module. The power acquisition module can be used to collect data such as current and voltage, and calculate power based on these data. The communication module can be used to transmit the collected power information. One end of the housing 10 is connected to the electrical plug 20 via a cable, and the electrical plug 20 is connected to the electrical device. The other end is connected to the power input plug 30 via a cable, and the power input plug 30 is connected to the power source, such as a 220V AC power source.

[0029] The usage process of this smart power cord is as follows: Connect the electrical plug 20 of the smart power cord to the electrical appliance, and connect the power input plug 30 to the power source. The power acquisition module integrated inside the smart power cord housing collects current and voltage data, and transmits this data through the communication module, so that the operator can determine the operating status of the electrical appliance, such as whether it is on, running, or off, based on this data.

[0030] The smart power cord provided in this embodiment integrates a power acquisition module and a communication module inside the power cord's casing, avoiding the need for additional installation and configuration of power monitoring equipment. It also reduces the risk of loss or reconfiguration of external acquisition equipment due to equipment migration. This simplifies the power information acquisition process, reduces costs, and enables convenient and quick acquisition of power information from electrical appliances.

[0031] Based on the foregoing embodiments, Figure 2 This is a schematic diagram of another smart power cord provided in an embodiment of the present invention.

[0032] like Figure 2 As shown, the power acquisition module is a power acquisition chip. The positive current input pin of the power acquisition chip is connected to the negative output line of the appliance plug 20, and the negative current input pin of the current acquisition chip is connected to the ground line of the power input plug 30. A first resistor is connected between the negative output line of the appliance plug 20 and the ground line of the power input plug 30. The voltage measurement pin of the power acquisition chip is connected to the phase line of the power input plug 30.

[0033] Specifically, the power acquisition module is a power acquisition chip U1, which includes a current input positive pin CIP, a current input negative pin CIN, and a voltage acquisition pin VP. The appliance plug CON1 has an output negative line OUT_N and a phase line AC_L; the power input plug CON2 has a ground line GND and a phase line AC_L. The CIP pin of U1 is connected to the OUT_N pin of CON1, and the CIN pin of U1 is connected to the GND pin of CON2. The OUT_N pin of CON1 and the GND pin of CON2 are connected by a first resistor R1, forming a closed loop to measure the current flowing through the power lines. The VP pin of U1 is connected to the AC_L pin of CON2 for voltage measurement.

[0034] In some embodiments, the positive current input pin of the power acquisition chip is connected to the negative output line of the appliance plug 20 through a second resistor, and the negative current input pin of the power acquisition chip is connected to the ground line of the power input plug 30 through a third resistor.

[0035] In some embodiments, the phase line of the power input plug 30 is connected in sequence to a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, and an eighth resistor, the voltage measurement pin of the power acquisition chip is connected between the seventh resistor and the eighth resistor, and the eighth resistor is grounded.

[0036] Continue to refer to Figure 2 As shown, a second resistor R2 is connected between the CIP pin of U1 and the OUT_N pin of CON1, and a third resistor R3 is connected between the CIN pin of U1 and the AC_L pin of CON2. Additionally, capacitor C1 is connected to the CIP pin of U1 and grounded, and capacitor C2 is connected to the CIN pin of U1 and grounded; these measures are to prevent excessive current from damaging the U1 chip. The AC_L pin of CON2 is connected to R4, R5, R6, R7, and R8 in sequence. The VP pin of U1 is connected between R7 and R8, with R8 grounded. This means that the 220V voltage is measured by a voltage divider formed by the series connection of R4 to R8.

[0037] Based on the aforementioned embodiments, current is collected by connecting the positive current input pin of the power acquisition chip to the negative output line of the appliance plug, and the negative current input pin of the power acquisition chip to the ground line of the power input plug. A first resistor is connected between the negative output line of the appliance plug and the ground line of the power input plug. Voltage is collected by connecting the voltage measurement pin of the power acquisition chip to the phase line of the power input plug. The power of the appliance is then calculated based on the current and voltage.

[0038] Based on the foregoing embodiments, Figure 3 This is a schematic diagram of another smart power cord provided in an embodiment of the present utility model.

[0039] like Figure 3 As shown, the smart power cord includes a housing 10; the housing 10 is equipped with a power acquisition module and a communication module for acquiring power information; one end of the housing 10 is connected to an appliance plug 20, and the other end of the housing 10 is connected to a power input plug 30; the communication module is a LoRa communication module; the LoRa communication module is connected to the power acquisition module for transmitting the power information.

[0040] Specifically, the LoRa communication module is a low-power, long-range wireless communication technology. The power acquisition chip is connected to the LoRa communication module. After the current acquisition device collects the power information, it transmits it to the corresponding server through the LoRa communication module. The corresponding server can perform various analyses on the power information, such as detecting the working status of electrical appliances.

[0041] In addition, to improve the security of power information transmission, the power information collected by the power acquisition chip can be first encoded in a custom way before being transmitted to the corresponding server. After decoding, the corresponding server can identify the working status of electrical equipment based on the decoded power information.

[0042] In some embodiments, a Bluetooth wireless module is further disposed inside the housing 10; the Bluetooth wireless module is connected to the LoRa communication module and is used to receive configuration of LoRa communication parameters of the LoRa communication module by the terminal device, and the terminal device is connected to the Bluetooth wireless module via Bluetooth.

[0043] Continue to refer to Figure 3 As shown, the housing 10 integrates a LoRa communication module and a Bluetooth wireless module. The Bluetooth wireless module is connected to the LoRa communication module and used for node parameter configuration. Field personnel can connect to the Bluetooth wireless module via Bluetooth using a handheld terminal device (such as a mobile phone). A specific application (APP) is installed on the terminal device, allowing users to configure and adjust the communication parameters of the LoRa communication module. This design allows users to conveniently manage and optimize the settings of the LoRa communication module through a mobile application, improving the flexibility and ease of use of the device.

[0044] In addition, the Bluetooth wireless module can also be connected to the power acquisition module to transmit the power information to the terminal device. In other words, the smart power cord can not only use the LoRa communication module to transmit power information to the corresponding server for remote monitoring, but also transmit power information to the terminal device of on-site personnel via Bluetooth so that on-site personnel can monitor it in real time.

[0045] like Figure 4 This is a schematic diagram of the structure of a Bluetooth wireless module provided in an embodiment of the present invention, as shown below. Figure 4As shown, the RX and TX pins of the power acquisition chip U are connected to the serial port of pins 7 and 8 of the Bluetooth wireless module, thereby enabling the acquisition of power information to be transmitted to the APP of the terminal device through the Bluetooth wireless module, and then sent to the corresponding server for analysis through the APP.

[0046] Additionally, there is a Bluetooth wireless module connection indicator light, which indicates whether LoRa communication parameters are being configured. (Continue to refer to...) Figure 4 As shown, the indicator light uses an LED. When the LED is off, it indicates that LoRa communication parameter configuration is not in progress; when the LED is on, it indicates that LoRa communication parameter configuration is in progress. Additionally, the VSW pin of the Bluetooth wireless module is connected to a DC-DC power supply circuit for filtering.

[0047] Preferably, the smart power cord will also undergo potting, waterproofing, high-temperature insulation, and other treatments to extend its service life.

[0048] Based on the aforementioned embodiments, the communication module is a LoRa communication module; the LoRa communication module is connected to the power acquisition module and is used to transmit the power information. The LoRa communication used has the advantages of low power, long transmission distance, and strong anti-interference.

[0049] Secondly, this utility model embodiment provides a power detection device. Figure 5 This is a schematic diagram of the structure of a power detection device provided in an embodiment of the present invention.

[0050] like Figure 5 As shown, the power detection device includes a smart power cord and an application server 40 as described above. The smart power cord is used to send the collected power information to the application server; the application server 40 is used to process the power information.

[0051] Specifically, the smart power line serves as a node (its structure is referenced). Figure 1 or Figure 3 As shown in the figure, it is wirelessly connected to the application server 40; after the smart power cord collects the current and voltage data of the electrical equipment, it sends them to the application server 40. The application server 40 parses, stores and analyzes the power information, such as analyzing the status of the electrical equipment, such as power on, power off, standby, abnormal, etc.

[0052] In some embodiments, the power detection device further includes a LoRa gateway 50, and the communication module disposed inside the housing of the smart power cord is a LoRa communication module; the LoRa gateway 50 is used to receive power information sent by at least one smart power cord through the LoRa communication module and forward it to the application server.

[0053] Continue to refer to Figure 5As shown, multiple smart power lines act as nodes (node ​​1, node 2... node N), and the collected power information is aggregated to the LoRa gateway 50 through the LoRa communication module and forwarded to the application server 40. The application server 40 parses, stores and analyzes the power information of each smart power line reported by the LoRa gateway.

[0054] The power detection device provided in this embodiment of the utility model collects power information from the smart power cord and sends it to the application server through a LoRa gateway. The application server analyzes the power information and identifies the working status of the electrical equipment.

[0055] Thirdly, this utility model embodiment also provides an electrical equipment power detection system. Figure 6 This is a schematic diagram of the structure of an electrical equipment power detection system provided in an embodiment of the present utility model.

[0056] like Figure 6 As shown, the electrical equipment power detection system includes electrical equipment 60 and power detection equipment as shown in the second aspect.

[0057] Specifically, the structural reference of the power detection equipment Figure 5 As shown, the smart power cord plug 20 is inserted into the electrical device 60, and the power input plug 30 of the smart power cord is inserted into the power supply. The current and voltage data of the electrical device 60 are collected, and the collected current and voltage data are sent to the application server 40 through the LoRa gateway 50 to realize the detection of the status of the electrical device 60.
