The detection terminal 40 of the present embodiment may be a portable terminal having a network connection function, such as a mobile phone, a tablet computer, or a dedicated terminal, and the present embodiment does not specifically limit the specific specification of the detection terminal 40. At the time of the detection, the detection terminal 40 is used for formulating a detection scheme corresponding to the detected refrigerator 20 and providing the detection scheme to the detection device 10 pre-connected to the detected refrigerator 20. After determining the detection result, the detection terminal 40 may be configured to display the detection result and perform subsequent processing.

In some embodiments, the detection terminal 40 may implement a detection function by installing an App (application program) for refrigerator detection, and may be connected to the detection device 10 through various wireless or wired communication methods, for example, may communicate with the detection device 10 through bluetooth.
The detection terminal 40 may be configured to: acquiring the specification and model information of the detected refrigerator 20; inquiring a power-making detection model of the detected refrigerator 20 according to the specification model information; making a detection scheme according to the electric detection model; the detection scheme is provided to the detection device 10 which is connected with the detected refrigerator 20 in advance, and the detection device 10 detects the detected refrigerator 20 according to the detection scheme. And the electric detection model is used for recording the test instruction and the judgment parameter threshold value corresponding to the test instruction. The detection scheme includes one or more test instructions and their corresponding decision parameter thresholds. 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 specification of the type 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 characteristics of the signal after each executing component 230 is turned on, such as the respective reasonable ranges of current, voltage and power. The detection terminal 40 can automatically determine the model specification information of the detected refrigerator 20 by scanning the code, image recognition, personnel input and other modes of the detected refrigerator 20, and further obtain the power-on detection model corresponding to the specification model information.
The specification and model information of the detected refrigerator 20 may be used to indicate a series of indexes such as brand, function, performance, quality, configuration, etc. of the refrigerator, and may be specifically composed of a set of letters and numbers with a certain rule. In general, the uniqueness of the kind of the detected refrigerator 20 can be determined using the specification model information.
The acquisition of the specification and model information of the detected refrigerator 20 by the detection terminal 40 can be performed by the following method:
firstly, scanning the label information of the detected refrigerator 20, and identifying the specification and model information according to the label information; the specification and model information is encoded in advance to form a label such as a barcode, a two-dimensional code, or the like. The label may be part of the tag or separately attached to the refrigerator 20 being tested. And the specification model information can be obtained by scanning the code. The tag information may be used as a means for identifying the detected refrigerator 20 during the after-sales process, and may also be used as an identifier of the refrigerator 20 during the factory inspection stage.
Secondly, the image of the detected refrigerator 20 is obtained, the specification and model information is obtained through image recognition, the detection terminal 40 can have a photographing function, the image of the detected refrigerator 20 is obtained through photographing the appearance and the interior of the compartment of the detected refrigerator 20, and then the specification and model information is obtained through an image recognition technology. In the detection of the detected refrigerator 20, the detection terminal 40 may provide a photographing instruction, such as an instruction of a photographing angle and a photographing region, perform pattern recognition based on the obtained image, and determine to obtain the specification model information.
Thirdly, input information for the detected refrigerator 20 is acquired, and specification model information is determined according to the input information. That is, the user or the after-sales maintenance personnel can input the specification model information or the related information in a manual input mode.
The three methods for acquiring the specification and model information can be selected or combined according to needs, for example, a label scanning method is preferably adopted to acquire the specification and model information, and if the reading of effective information cannot be realized under the conditions of label damage and the like, the specification and model information can be acquired through image recognition; in addition, if the specification model information determined by the label scanning mode or the image recognition mode is missing, the manual input information can be acquired for supplement. Those skilled in the art can select the manner of obtaining the specification and model information and the combination method of the obtaining manner according to the actual implementation requirement.

The detection terminal 40 in this embodiment can perform overall function and/or performance detection on all the execution components 230 of the detected refrigerator 20, and can select some execution components 230 to perform overall function and/or performance detection as required. The detection scheme may be generated according to the test instruction corresponding to the execution unit 230 selected from the electrical detection model to be detected and the corresponding determination parameter threshold. That is, the sensed items may be part or all of the functions of the sensed refrigerator 20. The actuating component 230 may also be referred to as an electrical load, and the actuation or change of the operating state may perform its own functions, such as lighting, refrigeration compressor, defrosting heating, sensing, and the like.
Wherein the electrical detection model may be pre-stored in the network service device 50. The network service device 50 provides data service to the detection terminal 40 on one hand and can also provide data service to the detected 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). That is, the network service device 50 stores in advance a correspondence between specification and model information of the refrigerator and the power generation detection model.
The network service device 50 may also have a data analysis function and a right management function, such as providing a detection right to the detection terminal 40 according to a detection request; and analyzing the detection result and the fault diagnosis request to obtain a fault solution.
The step of the detecting terminal 40 inquiring the power generation detection model of the detected refrigerator according to the specification model information may include: sending a query request including specification model information to the network service apparatus 50; and acquiring feedback data of the network service equipment 50 responding to the query request, and analyzing the feedback data to obtain an electric detection model. The sensing terminal 40 may establish a data connection with the network service device 50 through various network transmission means.
The electric detection model corresponds to the specification and model of the refrigerator 20 to be detected, and the detection scheme made by the electric detection model is in accordance with the actual configuration of the refrigerator 20 to be detected. Therefore, the detection scheme obtained by the method can meet the detection requirements of various refrigerators which are pre-configured with electric detection models, and the detection universality is greatly improved.
The test device 10 in cooperation with the test terminal 40 may 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 detection apparatus 10 of the refrigerator serves as an apparatus for directly supplying 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 communication line can adopt various communication modes, such as a serial communication mode. In this embodiment, the refrigerator 20 to be tested is connected via a communication line, so that the reliability of the test can be ensured.
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 detection scheme to the test port 221 through the instruction communication port 143, where the detection scheme may be configured as one or more according to a detection requirement, 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 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. Each test instruction may be used to test a different function of a particular component or set of components 230, such as adjusting a different power of the compressor to determine a frequency modulation function of the compressor, etc.
That is, the decision parameter threshold may comprise a reasonable threshold range of power supply parameters of the detected refrigerator 20 when executing the test instructions. The detection device 10 is used for supplying power to the detected refrigerator 20, and is provided with a measurement component for detecting a power supply parameter, so that a detection result is obtained by comparing a measurement result of the power supply parameter during the execution of the test instruction by the detected refrigerator 20 with a judgment parameter threshold value.
The detection terminal 40 may obtain the detection result fed back by the detection device after the step of providing the detection scheme to the detection device 10 pre-connected with the detected refrigerator, so as to be used for showing or further analyzing to after-sales maintenance personnel. For example, the detection terminal 40 may generate a corresponding detection result display interface according to the detection result, and display the detection result by using the display interface. For another example, the detection terminal 40 may forward the detection result to the data analysis device; and if the detection result indicates that at least one execution component of the detected refrigerator is abnormal, sending a fault diagnosis request to the data analysis equipment, so that the data analysis equipment analyzes the detection result and the fault diagnosis request to obtain a fault solution. The data analysis device may be integrated inside the detection terminal 40, and in other embodiments, the data analysis device may be disposed on the network side as a part of the network service device 50, and the fault diagnosis request is processed by using the big data analysis technology of the network device. The detection results may be saved locally at the detection terminal 40 and/or at the network service device 50 to form a historical detection record for use in subsequent invocations.
In addition, the detection terminal 40 can be used to manage after-sales services, and can perform detection only after authorization is obtained. For example, the detection terminal 40 further includes, before the step of sending the query request containing the specification model information to the network service apparatus 50: sending a detection authorization request to network service equipment 50, and verifying the detection authorization request by network service equipment 50; obtain authorization information provided by network service device 50 upon detecting that the authorization request has been verified. For example, the network service device 50 may obtain after-sales service information, which may be a repair application sent by the user, or the like. The network service device 50 compares the detection authorization request with the pre-received after-sales service information, and if the detection authorization request is matched with the pre-received after-sales service information, the network service device grants a detection authority to the detection terminal 40 of the after-sales maintainer. For example, when receiving the detection authorization request, the network service device 50 may provide corresponding authorization information by matching the responsible area of the after-sales maintenance staff with the repair information in the area.
The network service device 50 may also establish a data connection with the detected refrigerator 20. Authorization information can also be contained in the detection scheme provided by the detection terminal 40 to the detection device 10, so that the detection device 10 can determine the detection authority through the authorization information. Specifically, the detection terminal 40 provides the authorization information to the detection device 10, and the detection device 10 provides the authorization information to the main control board 220 of the detected refrigerator 20. The main control board 220 sends an authentication request to the network service device 50, and queries whether the authorization information matches with the authorization information provided by the network service device 50, and if not, the detection is considered as illegal. By the permission granting and verifying means, only the test instruction from the trusted detection terminal 40 can be executed, 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.
Fig. 3 is a schematic block diagram of a detection terminal 40 according to an embodiment of the present invention, and the detection terminal 40 may include a memory 410 and a processor 420, wherein the memory 410 stores a computer program 411, and the computer program 411 is executed by the processor 420 to implement any one of the detection methods of the refrigerator according to the embodiment. Processor 420 may be a single core processor, a multi-core processor, a computing cluster, or any number of other configurations. Memory 410 may include Random Access Memory (RAM), read only memory, flash memory, or any other suitable storage system.

step S408, providing the detection scheme to the detection device pre-connected to the detected refrigerator 20, and allowing the detection device 10 to detect the detected refrigerator 20 according to the detection scheme.
And the electric detection model is used for recording the test instruction and the judgment parameter threshold value corresponding to the test instruction. 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 specification and model information of the detected refrigerator 20 may be used to indicate a series of indexes such as brand, function, performance, quality, configuration, etc. of the refrigerator, and may be specifically composed of a set of letters and numbers with a certain rule. In general, the uniqueness of the kind of the detected refrigerator 20 can be determined using the specification model information.
Step S402 may include:
scanning the label information of the detected refrigerator 20, and identifying to obtain specification and model information according to the label information; and/or
Acquiring an image of the detected refrigerator 20, and identifying the image to obtain specification model information; and/or
Input information for the detected refrigerator 20 is acquired, and specification model information is determined based on the input information.
The three modes for determining the specification and model information can be selected or combined according to requirements. In the method of identifying the specification and model information according to the label information, the specification and model information can be encoded in advance to form labels such as bar codes and two-dimensional codes. The label may be part of the tag or separately attached to the refrigerator 20 being tested. And the specification model information can be obtained by scanning the code. The tag information may be used as a means for identifying the detected refrigerator 20 during the after-sales process, and may also be used as an identifier of the refrigerator 20 during the factory inspection stage.
In the mode of determining the specification and model information by image recognition, the image of the detected refrigerator 20 is obtained by shooting the appearance and the interior of the compartment of the detected refrigerator 20, and then the specification and model information is obtained by the image recognition technology.
In the mode of acquiring the input information, a user or after-sales maintenance personnel can input specification model information or related information in a manual input mode.
The three modes for determining the specification and model information can be combined for use, for example, a label scanning mode is preferably adopted to obtain the specification and model information, and if the reading of effective information cannot be realized under the conditions of label damage and the like, the specification and model information can be obtained through image recognition; in addition, if the specification model information determined by the label scanning mode or the image recognition mode is missing, the manual input information can be acquired for supplement. Those skilled in the art can select the manner of obtaining the specification and model information and the combination method of the obtaining manner according to the actual implementation requirement.
The information of the detected refrigerator 20 can be accurately and conveniently determined by the acquisition mode of the specification model information, and a foundation is provided for subsequent detection.
The electricity-making detection model may be pre-stored in the network service device 50, that is, the network service device 50 pre-stores the corresponding relationship between the specification and model information of the refrigerator and the electricity-making detection model, accordingly, step S404 may include: and sending a query request containing the specification and model information to the network service equipment 50, acquiring feedback data of the network service equipment 50 responding to the query request, and analyzing the feedback data to obtain the power-on detection model.
Step S406 may include: acquiring a detection request for indicating a detection item; determining a test instruction corresponding to the detection item from the power generation detection model according to the detection request; and generating a detection scheme according to the determined test instruction. The test items may be part or all of the functions of the tested refrigerator 20. In this embodiment, all the execution units 230 of the detected refrigerator 20 may be subjected to overall function and/or performance detection as required, and some execution units 230 may be selected as required to be subjected to overall function and/or performance detection. The detection scheme may be generated according to the test instruction corresponding to the execution unit 230 selected from the electrical detection model to be detected and the corresponding determination parameter threshold. When the overall detection is performed, the detection scheme may arrange all the functional test instructions in sequence to form a test instruction sequence. In the partial detection, the detection scheme may select one or more corresponding test instructions to form a test instruction sequence.
The electric detection model corresponds to the specification and model of the refrigerator 20 to be detected, and the detection scheme made by the electric detection model is in accordance with the actual configuration of the refrigerator 20 to be detected. Therefore, the detection scheme obtained by the method can meet the detection requirements of various refrigerators which are pre-configured with electric detection models, and the detection universality is greatly improved.
The decision parameter threshold may comprise a reasonable threshold range of the power supply parameter of the detected refrigerator 20 when executing the test instruction, and the detection device 10 is used for supplying power to the detected refrigerator 20 and is provided with a measurement component 141 for detecting the power supply parameter. The detection result is obtained by comparing the measurement result of the power supply parameter in the process of executing the test instruction by the detected refrigerator with the judgment parameter threshold value. That is, the detection apparatus 10 is used to supply power to the detected refrigerator 20, and is provided with a measurement component for detecting a power supply parameter, so that a detection result is obtained by comparing a measurement result of the power supply parameter during execution of the test instruction by the detected refrigerator 20 with the determination parameter threshold value.
The power supply parameters may include current values and/or voltage values and/or power values, and other parameters that may 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. 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.
The test command may cause the main control board 220 of the refrigerator 20 to control the 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.
Step S408 may be followed by: and acquiring a detection result fed back by the detection device 10. The test results are used for display to after-sales maintenance personnel or for further analysis. In some embodiments, the step of obtaining the detection result fed back by the detection device 10 further includes: and generating a corresponding detection result display interface according to the detection result. For example, the presentation interface may be generated by the detection 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.
In other embodiments, the step of obtaining the detection result fed back by the detection device 10 may further include: forwarding the detection result to the data analysis equipment; and if the detection result indicates that at least one execution component of the detected refrigerator is abnormal, sending a fault diagnosis request to the data analysis equipment, so that the data analysis equipment analyzes the detection result and the fault diagnosis request to obtain a fault solution. For example, the detection result indicates that at least one execution component of the detected refrigerator is abnormal, a fault diagnosis request can be sent to the data analysis device, so that the data analysis device can analyze the detection result and the fault diagnosis request to obtain a fault solution. The data analysis device may be integrated inside the detection terminal 40, and in other embodiments, the data analysis device may be disposed on the network side as a part of the network service device 50, and the fault diagnosis request is processed by using the big data analysis technology of the network device.
Before the step of sending the query request containing the specification model information to the network service device, the method further comprises the following steps: sending a detection authorization request to network service equipment 50, and verifying the detection authorization request by network service equipment 50; obtain authorization information provided by network service device 50 upon detecting that the authorization request has been verified. For example, the network service device 50 compares the detection authorization request with the pre-received after-sales service information, and if the detection authorization request is matched with the pre-received after-sales service information, the network service device grants the detection authority to the detection terminal 40 of the after-sales maintenance staff. For example, when receiving the detection authorization request, the network service device 50 may provide corresponding authorization information by matching the responsible area of the after-sales maintenance staff with the repair information in the area. The detection authorization request can include information such as an account key of the after-sales maintenance personnel, and the detection authority is granted only after the after-sales maintenance personnel is scheduled for corresponding service work, so that the detection work is managed.
In addition, authorization information may be further included in the detection scheme provided in step S408, so that the detection device 10 can determine the detection authority through the authorization information. Specifically, the authorization information received by the detection device 10 can be provided to the main control board 220 of the detected refrigerator 20. The main control board 220 sends an authentication request to the network service device 50, and queries whether the authorization information matches with the authorization information provided by the network service device 50, and if not, the detection is considered as illegal. By the permission granting and verifying means, only the test instruction from the trusted detection terminal 40 can be executed, 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.

After the detection device 10 is powered on, the refrigerator 20 is first kept powered off, and the connection of the detection terminal 40 is prompted. The detection terminal 40 starts a detection APP, and establishes a data connection with the detection device 10 in a bluetooth manner or the like.
The detection terminal 40 logs in the account of the after-sales service person, and then grants the detection authority to the network service device 50 according to the detection terminal 40 of the after-sales service person. After the data connection between the detection terminal 40 and the 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 service device 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 test terminal 40 provides the test instruction to the test device 10 by means of encrypted communication. The detection device 10 verifies the detection terminal 40, and after determining that the detection terminal 40 passes the verification (i.e., has the detection authority), decrypts the encrypted data to obtain the test instruction. The detection device 10 powers on the detected refrigerator 20 to make it enter a detection state, and maintains all the execution parts 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 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.

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 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.
