The housing 150 can be provided with a power access port 110, an instruction communication port 143, a power output port 120, a display device 145, and the like. The power access port 110 is used for connecting an external power source 30 (for example, a power grid power source), and may be in the form of a power connector adapted to the power source 30, such as a three-wire power plug, to cooperate with a three-wire connecting wire, and finally connect to the live wire L, the neutral wire N, and the ground wire GND of the power source 30. The power access port 110 has at least a power ground 111 for connecting a power ground, and when a three-core power plug is used, the power ground 111 is a core located at the center.
A plurality of magnetic electrodes 131, which are spaced apart from each other on the surface of the casing 150, are attached to the exposed metal region on the outer surface of the refrigerator body of the refrigerator 20 to be tested by magnetic force, and each magnetic electrode 131 is connected to the power ground via an independent electrode ground line.
The magnetic force of the magnetic electrode 131 is required to satisfy the requirement of attaching the intelligent detection device 10 to the exposed metal area of the outer surface of the refrigerator body of the detected refrigerator 20. Generally, the back plate of the refrigerator housing is a metal plate, the refrigerator housing itself needs to be reliably grounded, and after the intelligent detection device 10 is attached to the back plate of the housing of the detected refrigerator 20, the magnetic electrode 131 realizes reliable connection with the housing of the detected refrigerator 20.
The housing 150 of the smart detection device 10 is a square box or other portable shape, the shape shown in the figure is only an example, and the shape of the housing 150 can be selected according to specific use requirements.
The smart detection device 10 for a refrigerator of the present embodiment may further be provided with a sheath 151. The sheath 151 is disposed on the outer side of the housing 150, and an opening is disposed at a position of the sheath 151 opposite to the plurality of magnetic electrodes 131 for the magnetic electrodes 131 to pass through, and the plurality of magnetic electrodes 131 are further disposed to protrude from the outer surface of the sheath 151. The sheath 151 may prevent the housing 150 from being knocked on the one hand, and may be convenient to hold on the other hand. The plurality of magnetic electrodes 131 protrude from the outer surface of the sheath 151, so as to be attached to the refrigerator 20 to be tested.
Fig. 4 is an electrical connection schematic diagram of the smart detection device 10 of the refrigerator according to one embodiment of the present invention. The smart detection device 10 further includes a power connection bank 130. The intelligent detection device 10 is further provided with a power output port 120 on the outer casing 150 for connecting a refrigerator power connector 210 of the detected refrigerator 20, and the power output port 120 is provided with a refrigerator ground terminal 121 for connecting a ground wire of the detected refrigerator. The power output port 120 is generally adapted to a power connector 210 of the tested refrigerator 20, such as a three-wire socket, wherein the refrigerator ground terminal 121 is used for connecting a ground terminal of the power connector 210.
The power connection line set 130 is connected between the power access port 110 and the power output port 120 to transfer the electric power from the external power source 30 to the power output port 120, and the power connection line set 130 has a ground connection line connected between the power ground and the refrigerator ground 121. One end of the power connection wire set 130 is connected to a power supply through the power access port 110, for example, the power connection wire set can be respectively connected to a live wire L, a neutral wire N, and a ground wire GND of the power supply 30; the other end of the power connection line set 130 is connected to a power connector 210 of the detected refrigerator 20 through the power output port 120.

In some embodiments, the electrode ground lines corresponding to the plurality of magnetic electrodes 131 may be respectively connected to different sections of the ground connection line, and through the respective ground connections, it may be ensured that when an unexpected fault occurs in one magnetic electrode 131 or the electrode ground line, the other magnetic electrodes 131 still ensure reliable ground connection. Since the magnetic electrodes 131 are attached to the exposed metal regions on the outer surface of the case body, and the case body is grounded, the ground protection can be realized by only grounding any one of the magnetic electrodes 131 through the above structure. By optimizing the arrangement of the magnetic electrodes 131, the grounding reliability is improved. After the intelligent detection device 10 is attached to the metal shell of the detected refrigerator 20, the ground of the intelligent detection device 10 is communicated with the ground of the refrigerator 20, so that the ground faults caused by various accidents such as poor contact of the power supply ground terminal of the intelligent refrigerator 20, poor contact of the refrigerator ground terminal 121, breakage of the power supply ground wire and the like are avoided. Therefore, the smart detection device 10 of the present embodiment can reliably ensure the power supply 30, the smart detection device 10, and the refrigerator 20 to be tested to be grounded through the magnetic electrode 131.

Fig. 5 is a system schematic diagram of the smart detection device 10 of the refrigerator in a detection state according to one embodiment of the present invention, and fig. 6 is an electrical connection schematic diagram of the smart detection device 10 of the refrigerator in a detection state according to one embodiment of the present invention. The smart detection apparatus 10 of the refrigerator may be further provided with a measurement component 141, a data processing module 142, an instruction communication port 143, a data transmission module 144, a display device 145, and the like. The above-described detection means may be configured as necessary.
The measuring assembly 141 is disposed in the casing 150, connected to the power connection line set 130, and configured to detect a current value and/or a voltage value of the power connection line set 130 supplied to the detected refrigerator 20. The measurement unit 141 may include a current detection element and a voltage detection element, and a power value may be further calculated by detecting the obtained current value and voltage value. The current value, the voltage value and the power value reflect the operation state of the detected refrigerator 20. Since there is a difference in the use of electric energy by different executing parts of the refrigerator 20 to be tested while performing their respective functions, this is directly reflected in the current value, the voltage value, and the corresponding power value.
The data processing module 142, disposed within the housing 150, may be configured to determine an operating state of the detected refrigerator 20 according to the current value and/or the voltage value. The data processing module 142 may perform various analysis operations on the current and/or voltage values, such as calculating power values, analyzing currents (e.g., amplitude, frequency, trend), analyzing voltages (e.g., amplitude, frequency, trend), and so on. Since the analysis and calculation of various electrical signals are known per se by those skilled in the art, they will not be described herein.
In order to comprehensively analyze whether various functions of the detected refrigerator 20 are normal, the command communication port 143 of the intelligent detection device 10 may be configured to be connected to a test port 221 preset on the main control board 220 of the detected refrigerator 20 through a communication line. The data processing module 142 is further connected to the instruction communication port 143, and is configured to send a test instruction sequence to the test port 221, where the test instruction sequence includes one or more test instructions configured according to a set order, and each test instruction is used to enable the main control board 220 to issue a corresponding action instruction to one or more execution units; and determines the action execution result of the execution part according to the current value and/or the voltage value in the process of sending the test instruction sequence to the test port 221. The performing components may include various load components of the refrigerator 20 to be tested, such as a refrigeration system (compressor, etc.), a fan, a defrost heater, a vertical beam heater, lights, other auxiliary functional components (display screen, camera, sensing device, fresh keeping device), and so on. The different models of the refrigerator 20 may be configured with different performing components.
That is, the smart detection device 10 sends one or more test instructions to the detected refrigerator 20, and each test instruction may cause the main control board 220 of the refrigerator 20 to control one or more execution units to complete or change the operation status. If the current, voltage, power, etc. of the detected refrigerator 20 are changed due to different actions of the executing components, the data processing module 142 can determine whether the action executing result of the executing component is correct according to the current value and/or the voltage value and other corresponding electrical signal characteristic quantities.
For example, the test command may sequentially turn on the defrosting heater, the lighting lamps in each compartment, the air supply fans, the compressor, and other components, and the main control board 220 may be used to send an action command, or may determine whether the function of the main control board 220 is correct. The test instructions may be pre-configured according to the function of the refrigerator 20 being tested. The command communication port 143 may communicate with the refrigerator main control board 220 through various communication means, such as serial communication, parallel communication, or other communication bus means.
In consideration of the great difference in the functions and configurations of the detected refrigerator 20, the intelligent detection device 10 of the present embodiment may also automatically configure the test instructions according to the model of the detected refrigerator 20 by means of big data technology. For example, the data transmission module 144 is connected to the data processing module 142, and is configured to establish a data connection with the external detection terminal 40, acquire a test instruction sequence provided by the detection terminal 40, and send an action execution result to the detection terminal 40.
The detection terminal 40 may be a portable terminal having a network connection function, such as a mobile phone, a tablet computer, or a dedicated terminal. During detection, the detection terminal 40 determines the model specification of the detected refrigerator 20, and searches the electric detection model of the detected refrigerator 20 in the management server connected to the refrigerator through the network. The electric detection model may be prepared in advance in the production detection stage of the detected refrigerator 20, for example, as the basis for factory detection of the detected refrigerator 20. The electric detection model can comprise the type specifications of the execution components of the refrigerator configuration (such as the number of compartments, the number of evaporators, the number of fans, the number and configuration state of illuminating lamps, the specification of defrosting heating wires, the configuration state of fresh-keeping auxiliary equipment, the specification of vertical beam heating wires, the configuration and specification of various intelligent equipment) and the respective reasonable ranges of current, voltage and power of each execution component after being started. For example, the detection terminal 40 may automatically determine the model specification of the detected refrigerator 20 by scanning the code, image recognition, and the like of the detected refrigerator 20, and further obtain the electrical detection model and the corresponding test instruction and judgment threshold range.
The detection terminal 40 may implement a detection function by installing an App (application program) for refrigerator detection, and may be connected to the smart detection device 10 in various wireless or wired communication manners, for example, may communicate with the smart detection device 10 through bluetooth.
The detection terminal 40 provides the test instruction and the corresponding determination threshold range (the voltage value reasonable range, the current value reasonable range, the power value reasonable range, the variation speed of various electric signals, etc.) to the intelligent detection device 10 through the data transmission module 144, and the data processing module 142 can perform the state detection of the refrigerator 20 to be detected according to the test instruction and the determination threshold range provided by the detection terminal 40. If the detected refrigerator 20 executes the action corresponding to the test instruction and the detection result of the measurement component 141 is within the corresponding reasonable range, the data processing module 142 may determine that the execution component corresponding to the test instruction operates normally; otherwise, the data processing module 142 may determine that the execution unit corresponding to the test instruction operates abnormally. The data processing module 142 may perform multiple detections on one execution component at a specific determination time to avoid a deviation of a single detection.
Data transmission module 144 may also be configured to provide the action execution results to detection terminal 40 for output by detection terminal 40. For example, the inspection terminal 40 may display the respective execution components of the inspected refrigerator 20 and the inspection results thereof on its own screen. The test terminal 40 may also obtain the selection operation of the after-market maintenance staff on its own screen, generate a test instruction according to the selected execution component, and display the test result according to the action execution result provided by the data transmission module 144. In other embodiments, the detection terminal 40 may also upload the detection result to a network server, which may be used to record the detection result of the detected refrigerator 20 and provide a repair recommendation and a parts ordering recommendation when a fault occurs.
When the action execution result corresponding to any test instruction does not match the expected result, the data processing module 142 may output a notification message indicating that the execution unit corresponding to the test instruction is faulty. The prompt may be output by the test terminal 40 for reporting to after-market maintenance personnel.
And a display device 145 disposed at the display opening of the housing 150, connected to the data processing module 142, and configured to display the operation state of the detection apparatus 10. For example, before detection, the display device 145 may be used to display the connection state of the smart detection apparatus 10 and the detection terminal 40 (for example, connected to the terminal App, or a detection terminal to be connected, etc.); during the detection process, the display device 145 may be used to display the currently detected items (e.g., basic function detection, light detection, air supply detection, defrosting detection, etc. of the main control panel 220), and after the detection is completed, the display device 145 may be used to display the detection result (e.g., overall normal, some component abnormal, etc.).
In some embodiments, the smart detection device 10 has an overall flattened box shape, wherein the back portion is used for arranging a plurality of magnetic electrodes 131 to be attracted to the refrigerator 20, and the top or bottom portion is provided with a power access port 110 for connecting to the power supply 30. For convenience of operation, a power output port 120, a display device 145, and an instruction communication port 143 connected to the refrigerator 20 may be disposed at the front surface. In addition, the intelligent detection device 10 can also be provided with buttons or other input devices as required to realize local operation devices such as switches, resets and the like.
Because the intelligent detection device 10 of the embodiment performs reliable grounding connection, after-sales maintenance personnel can safely perform various operations, thereby ensuring the safety of the connection and the test process and providing safety guarantee for efficient and accurate detection.
In addition, the whole detection process of the intelligent detection device 10 of the refrigerator of the embodiment is automatically performed, whether the corresponding execution component functions normally is determined through the electric signal change corresponding to the action of the refrigerator responding to the test instruction sequence, the detection is accurate, and the efficiency is high. The test instruction is obtained by the detection terminal 40 (such as a mobile phone, a mobile terminal, a tablet, etc.) according to the power supply detection model of the detected refrigerator 20, and the data transmission module 144 of the intelligent detection device 10 obtains the test instruction matched with the detected refrigerator 20 from the test terminal, so that the detection requirements of refrigerators 20 of different models and different functions are met, the universality is greatly improved, and the working efficiency of after-sales personnel is improved.
The using process of the intelligent detection device 10 applying the refrigerator of the embodiment may specifically include: the after-sales service person receives the order to check the checked refrigerator 20. First, after-sales service personnel powers off the refrigerator 20 and removes the shutter of the refrigerator 20 to expose the test port 221 from the main control board 200. The intelligent detection device 10 is connected with the detected refrigerator 20 through a cable, a power plug of the refrigerator 20 is inserted into the power output port 120, the power access port 110 is connected with the power supply 30, and the instruction communication port 143 is connected with the test port 221 through a communication cable. After the intelligent detection device 10 is powered on, the refrigerator 20 is firstly kept powered off, and the connection detection terminal 40 is prompted. The detection terminal 40 starts a detection APP (corresponding APP can be developed according to the system of the detection terminal 40), and establishes a data connection with the intelligent detection device 10 through bluetooth or other wireless communication modes.
After the data connection between the detection terminal 40 and the intelligent detection device 10, the model of the detected refrigerator 20 is obtained through code scanning or other identification methods, meanwhile, the information (such as the number, the model, the specification, the configuration, the user information, and the like) of the detected refrigerator 20 is provided to the network server, the power-making detection model (including the test instruction and the corresponding judgment basis) of the detected refrigerator 20 is obtained, and the detection terminal 40 forms a detection scheme.
The detection scheme may be used to detect the detected refrigerator 20 in its entirety or to detect a portion of the executing components. The detection terminal 40 provides a test instruction to the intelligent detection device 10 through an encrypted communication mode. The intelligent detection device 10 verifies the detection terminal 40, and after the detection terminal 40 is determined to pass the verification (i.e., has the detection authority), decrypts the encrypted data to obtain the test instruction. The intelligent detection device 10 powers on the detected refrigerator 20 to enable the detected refrigerator to enter a detection state, and all execution components are maintained in a standby state.
After determining that the electrical signal parameters of the detected refrigerator 20 entering the detection state are normal and obtaining the correct feedback of the main control board 220, the intelligent detection device 10 sends the test instructions according to the sequence of the detection scheme, so that the main control board 220 sends the action instructions to one or more execution units.
The refrigerator 20 receives the test command, turns off all other loads (no tested execution unit), and activates or changes the operation state of the execution unit corresponding to the operation command. In the action process of the execution component, the measurement component 141 continuously collects the power supply signal of the detected refrigerator 20, and the sampled value is filtered to obtain a current value, a voltage value, a power value and part or all of other electric signals. The measured electrical signal parameters and the corresponding judgment basis are judged, and if the detection result is in the corresponding reasonable range, the data processing module 142 can judge that the execution component corresponding to the test instruction operates normally; otherwise, the data processing module 142 may determine that the execution unit corresponding to the test instruction operates abnormally.
The smart detection device 10 provides the action execution result to the detection terminal 40 for output. The detection terminal 40 may output the detection result on the interface for detecting the APP. For example, for a normally functioning execution unit, it is identified in green; the execution unit for the abnormal operation is identified in red. After-sale maintenance personnel can instruct the abnormal execution component to be tested independently through operation on the interface, so that the detection accuracy is improved.
