Detailed Description
Fig. 1 and 2 are schematic diagrams of an angle of a smart detection device 10 of a refrigerator according to an embodiment of the present invention. Wherein fig. 1 mainly shows the shape of the side of the smart detection device 10 facing away from the detected refrigerator 20 (the side facing the detected person), and fig. 2 mainly shows the shape of the side of the smart detection device 10 facing towards the detected refrigerator 20 (the side abutting against the refrigerator 20). Fig. 3 is an electrical schematic block diagram of the smart detection device 10 of the refrigerator according to one embodiment of the present invention.
The smart detection device 10 of the refrigerator of the present embodiment may generally include: the power supply system comprises a power supply access port 110, a power supply output port 120, a power supply connecting wire 130, a measuring component 141, a data processing module 142 and an instruction communication port 143.
The power access port 110 is used for connecting an external power source 30 (for example, a power source of a power grid), 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 output port 120 is used for connecting a power connector 210 of the detected refrigerator 20. The power output port 120 is generally adapted to a power connector 210 of the tested refrigerator 20, such as a three-wire socket.
The power connection line 130 is connected between the power access port 110 and the power output port 120 to transfer power from the external power source 30 to the power output port 120. That is, the smart detection device 10 of the refrigerator serves as a device that directly supplies power to the detected refrigerator 20. One end of the power connection line 130 is connected to the power supply through the power access port 110, for example, the live line L, the neutral line N, and the ground line GND of the power supply 30 can be connected respectively; the other end of the power connection line 130 is connected to a power connector 210 of the detected refrigerator 20 through the power output port 120.
The command communication port 143 is used for connecting a test port 221 preset on the main control board 220 of the detected refrigerator 20 through a communication line. The instruction communication port 143 sends a test instruction to the test port 221, where the test instruction is used to enable the main control board 220 to send an action instruction to one or more execution units 230 of the detected refrigerator. The performing part 230 may include various load parts of the refrigerator 20 to be tested, such as a refrigerating system (a compressor, etc.), a fan, a defrosting heater, a vertical beam heater, a light, other auxiliary functional parts (a display screen, a photographing device, a sensing device, a refreshing device), and the like. The different models of the refrigerator 20 may be configured with different executing components 230. Since different actuators 230 of the detected refrigerator 20 have different uses of electric energy when performing their respective functions, this is directly reflected in the parameter changes of electric signals such as current value, voltage value, power value, etc.
The measuring component 141 is connected to the power connection line 130 and configured to detect one or more parameters of the electrical signals supplied by the power connection line 130 to the detected refrigerator 20, and the parameters of the electrical signals may include a current value and/or a voltage value and/or a power value, and other parameters that can be analyzed based on the above data, including but not limited to: one or more of a voltage value, a current value, an electrical signal waveform, a power value, a harmonic content, and the like. For example, the measurement component 141 may include a current detection element and a voltage detection element, and a power value or other further parameters may be further calculated by detecting the current value and the voltage value. The current value, the voltage value and the power value reflect the operation state of each actuator 230 of the refrigerator 20 to be tested. Since there is a difference in the use of electric power by the different actuators 230 of the refrigerator 20 to be tested in performing their respective functions, this is directly reflected in the current value, the voltage value, the power value, and other parameters.
And the data processing module 142 is configured to determine an action execution result of the execution unit 230 according to the parameter after the test instruction is sent to the test port 221. The data processing module 142 may perform various analysis operations on one or more of the current values, voltage values, power values, or other electrical signal parameters, 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.
The data processing module 142 may send a test instruction sequence to the test port 221 through the instruction communication port 143, 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 230; and determines the action execution result of the execution part 230 according to the value of the electric signal parameter measured by the measurement component 141 in the process of sending the test instruction sequence to the test port 221.
The smart detection device 10 sends one or more test instructions to the detected refrigerator 20, and each test instruction can cause the main control board 220 of the refrigerator 20 to control one or more execution units 230 to complete or change the operation state. If the current, voltage, power, etc. of the detected refrigerator 20 are changed due to the actions of different executing components 230, the data processing module 142 may determine whether the action of the executing component 230 is correct according to the current value and/or the voltage value and/or other electrical signal parameters. 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 means.
In some embodiments, the smart detection device 10 may also be used to test a certain or a certain group of the execution units 230 for different functions, such as adjusting different powers of the compressor to determine a frequency modulation function of the compressor, and the like.
The housing 150 of the smart detection device 10 of the present embodiment may be a square box or other portable shape, the shape shown in the figures is only an example, and the shape of the housing 150 may be selected according to specific use requirements. A plurality of magnetic electrodes 131 spaced apart from each other on the back of the casing 150 for being attached to the exposed metal region of the outer surface of the refrigerator body of the refrigerator 20 to be tested by magnetic force, and each of the magnetic electrodes 131 is connected to a power ground via an independent electrode ground.
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 magnetic electrode 131 provides a fixing means for the intelligent detection device 10 and the detected refrigerator 20, and provides reliable grounding protection, so that the electric shock risk caused by poor grounding is avoided. The intelligent detection device 10 is attached to the refrigerator 20 through magnetic force, so that reliable connection between the magnetic electrode 131 and the refrigerator 20 is also shown, grounding can be visual, and reliability is greatly improved. That is, the magnetic force can ensure that the smart detection device 10 is attached to the refrigerator 20, and also ensure that the magnetic electrode 131 is reliably connected to the outer case of the refrigerator 20.
The intelligent detection device 10 of the refrigerator of the present embodiment may further be provided with a sheath. The sheath is sleeved on the outer side of the shell 150, so that the shell 150 can be prevented from being collided, and the sheath can be conveniently held by hands.
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, the front face may be arranged to connect the power output port 120, the display device 145, and the command communication port 143 of the refrigerator 20. 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.
The smart detection device 10 is attached to the detected refrigerator 20 by magnetic attachment, which facilitates the operation of after-sales maintenance personnel and improves the reliability of grounding.
The test instruction can be configured in advance, and in consideration of the great difference between the functions and the configuration of the detected refrigerator 20, the intelligent detection device 10 of the embodiment can also automatically configure the test instruction according to the model of the detected refrigerator 20 by means of big data technology. Such as identifying the model and configuration of the detected refrigerator 20 and invoking the corresponding test protocol. In some embodiments, multiple test instructions may be executed in sequence to complete the testing of the entire refrigerator 20 under test.
Fig. 4 is an electrical connection schematic diagram of the smart detection device 10 of the refrigerator according to another embodiment of the present invention, and fig. 5 is a system schematic diagram of the smart detection device 10 of the refrigerator shown in fig. 4 for detection. In order to further facilitate and universality and meet detection requirements of more refrigerators, the intelligent detection device 10 of the refrigerator of the embodiment can be obtained by the detection terminal 40 (such as a mobile phone, a mobile terminal, a tablet and the like) according to an electricity making detection model of the detected refrigerator 20, and the data transmission module 144 of the intelligent detection device 10 obtains a test instruction matched with the detected refrigerator 20 from the detection terminal 40, so that detection requirements of refrigerators with different models and different functions are met, the universality is greatly improved, and the work efficiency of after-sales personnel is improved.
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 the detection, the detection terminal 40 determines the model specification of the detected refrigerator 20, and searches the power detection model of the detected refrigerator 20 in the server 50 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 may include the type specification of the executing component 230 configured in the refrigerator (e.g. the number of compartments, the number of evaporators, the number of fans, the number and configuration state of lighting 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 devices), and the respective reasonable ranges of current, voltage and power after each executing component 230 is turned on. For example, the detection terminal 40 may automatically determine the model specification of the detected refrigerator 20 by scanning the code, image recognition, personnel input, and the like of the detected refrigerator 20, and further obtain an electrical detection model and a corresponding test instruction and a 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.
And the data transmission module 144 is connected with the data processing module 142, and is configured to establish data connection with the external detection terminal 40 and obtain the test instruction provided by the detection terminal 40, and the test instruction is formulated by the detection terminal 40 according to the power supply detection model of the detected refrigerator 20, so that the detection of different types of refrigerators is satisfied.
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.
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 units 230 of the inspected refrigerator 20 and the inspection results thereof on its own screen. The inspection terminal 40 may also acquire a selection operation of the after-market maintenance worker on its own screen, generate a test instruction according to the selected execution part 230, and display an inspection result according to an action execution result provided by the data transmission module 144. In other embodiments, the detection terminal 40 may also upload the detection result to the network server 50, and the network server 50 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 failure occurs.
In addition, the server 50 provides data services to the detection terminal 40 on one hand and can also provide data services to the intelligent refrigerator 20 on the other hand, for example, as a management device of the refrigerator 20, for example, data connection can be made with the refrigerator 20 through a network to acquire operation parameters of the refrigerator 20 and other data (such as storage information). The server 50 may be a computing system that provides network services, including or otherwise implemented by one or more server computing devices. Where multiple server computing devices are included, such server computing devices may operate according to a sequential computing architecture, a parallel computing architecture, or some combination thereof.
The data transmission module 144 may communicate with the detection terminal 40 by means of encrypted data connection, and after establishing data connection with the detection terminal 40, receive encrypted data from the detection terminal 40, and decrypt the encrypted data to obtain a test instruction. That is to say, the detection terminal 40 adopts an encryption means to perform data transmission, and the intelligent detection device 10 of the refrigerator only executes a test instruction from the trusted detection terminal 40, so that illegal detection is avoided, data security is improved, and the situation that a fitting is falsely cheated due to a false fault is avoided.
The data transmission module 144 may further obtain a decision criterion corresponding to the test instruction provided by the detection terminal 40, where the decision criterion includes a parameter threshold range. The parameter threshold range is determined according to the characteristics of the parameters of the power signal when the different actuators 230 of the detected refrigerator 20 are operated or perform state transition, and may include ranges of current values and/or voltage values and/or power values, such as a reasonable range of voltage values, a reasonable range of current values, a reasonable range of power values, and the variation speeds of various electrical signals. Each test instruction may correspond to one or more sets of criteria.
The data processing module 142 may also be configured to: comparing the parameters measured by the measurement component 141 with the corresponding parameter threshold ranges; and determining the action execution result of the execution unit 230 according to the comparison result, wherein the parameters include: current values and/or voltage values and/or power values. The data processing module 142 can perform the status detection of the refrigerator 20 to be detected according to the test instruction and the parameter 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 230 corresponding to the test instruction operates normally; otherwise, the data processing module 142 may determine that the execution unit 230 corresponding to the test instruction operates abnormally. The data processing module 142 may perform multiple detections on one execution block 230 at a specific decision to avoid a single detection deviation.
In the case that the action execution result corresponding to any test instruction does not match the expected result, the data processing module 142 may output a prompt message indicating that the execution component corresponding to the test instruction is faulty. The prompt may be output by the test terminal 40 for reporting to after-market maintenance personnel.
The measurement component 141 may also be configured to sample the electrical signals supplied by the power connection line set to the detected refrigerator, and perform filtering calculation on a set number of sampling results to obtain parameters. For example, the measurement unit 141 continuously performs a set number of sampling operations, for example, 10 sampling operations, and then performs a filtering calculation on the sampling results, thereby eliminating detection errors due to measurement errors.
The data transmission module 144 is further configured to authenticate the test terminal 40 to determine whether the test terminal is authorized for testing prior to establishing a data connection with the test terminal 40. The verification may be performed by reading the identification of the detection terminal 40 or by verifying the key of the detection terminal 40. The detection terminal 40 may update its own key for verification by the data transmission module 144 after authorization by the network server 50.
For the intelligent refrigerator 20 with the network connection function, a preferred verification method is as follows: the communication port 143 is instructed to transmit verification information (such as an identifier, a key, etc.) of the detection terminal 40 to the main control board 220 through the test port 221, the main control board 220 sends a verification request to the network service through its own network interface, and determines whether the detection terminal 40 is a valid detection device according to a reply of the network server 50. For an illegal detection terminal, the intelligent detection device 10 refuses to execute the test instruction provided by the intelligent detection device. That is, the web server 50 manages the after-sales maintenance staff by managing the inspection terminal 40.
The smart detection device 10 can also detect the main control board 220 of the detected refrigerator 20. The command communication port 143 obtains a response command to the test command fed back by the main control board 220 through the test port 221. The data processing module 142 is further configured to determine the operation status of the main control board 220 according to the response instruction. Generally, the main control board 220 enters a detection state after the test port 221 receives the test command, and then replies with a response command (e.g., an execution result of the test command). The smart detection device 10 may determine whether the main control board 220 operates normally according to the response command returned by the main control board 220.
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, the front face may be arranged to connect the power output port 120, the display device 145, and the command communication port 143 of the refrigerator 20. 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.
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, 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-on 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 with different models and different functions are met, the universality is greatly improved, and the work efficiency of after-sales personnel is improved.
Further, the intelligent detection device 10 of the refrigerator of the embodiment only allows the legal detection terminal 40 to perform detection through the verification and encrypted transmission of the detection terminal 40, so that the background management is facilitated, and the false detection and the false order condition are avoided.
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 the detection APP, and establishes a data connection with the intelligent detection device 10 in a bluetooth manner or the like.
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, etc.) of the detected refrigerator 20 is provided to the network server 50, 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 execution unit 230. 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 make it enter a detection state, and maintains all the execution components 230 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 test instructions according to the sequence of the detection schemes, so that the main control board 220 sends action instructions to one or more execution units 230.
The refrigerator 20 receives the test command, turns off all other loads (no tested execution unit), and the execution unit 230 corresponding to the action command starts or changes the operation state. In the action process of the executing component 230, the measuring component 141 continuously collects the power supply signal of the detected refrigerator 20, and the sampled value is subjected to filtering operation 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 230 corresponding to the test instruction operates normally; otherwise, the data processing module 142 may determine that the execution unit 230 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 properly functioning execution component 230, it is identified in green; execution component 230 for the running exception is identified in red. After-sales maintenance personnel can instruct the abnormal execution component 230 to be tested again individually by operating on the interface, so as to improve the detection accuracy.
After the multiple detections are completed, the detection APP of the detection terminal 40 may upload the detection result to the network server 50 for data trace detection. The server 50 may analyze the execution component with abnormal operation result according to big data calculation, form a maintenance suggestion and a method, give a maintenance guidance suggestion, and send the suggestion to the detection terminal 40. After-sale maintenance personnel can perform troubleshooting maintenance according to maintenance guide suggestions, so that the rapid detection of refrigerator faults, the rapid positioning of the faults and the data retention are realized, the accessories can be managed, and the condition that the accessories are acquired through false detection is avoided.
