[0023] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] In this document, the term "and / or" merely describes a relationship, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Furthermore, the term "at least one" in this document means any combination of at least two of any one or more elements. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0026] Research has revealed that in existing technologies, various test loads and sensors are connected to the control cabinet using a single set of wiring. This single-set wiring method consumes a significant amount of connection time, thereby reducing the control cabinet's testing efficiency. Furthermore, this method is prone to errors such as incorrect wiring between external loads and sensors and the control cabinet.

[0027] To facilitate understanding of this embodiment, a control cabinet testing method disclosed in this disclosure will first be described in detail. The execution subject of the control cabinet testing method provided in this disclosure is generally an electronic device with a certain computing power.

[0028] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0029] Please see Figure 1 The present invention provides a flowchart of a control cabinet testing method, including the following steps S101 to S107:

[0030] S101. Establish the signal correspondence between each connection position of the connection device and the input / output signals of the control cabinet under test; wherein, the connection device is used to realize the communication connection between the test load and the control cabinet under test.

[0031] Here, the connection device includes connectors and plugs, wherein there are multiple connectors, and one end of each connector is communicatively connected to the test equipment; the plugs (i.e. Figure 2 The terminal block 5 and the wire clamp 6 shown are illustrated, wherein the connector includes multiple insertion holes for inserting the other end of the connector plug, and the connector is configured to communicate with the control cabinet under test. Figure 2 The diagram shown is a structural schematic of the connector plug in the connecting device. From Figure 2 It can be seen that the connector plug of the connector device includes a top cover 1, a wire spring pin 2, a base 3, and a limiting block 4. The connector plug can also be called a self-resetting telescopic connector mechanism.

[0032] In the embodiments of this disclosure, the test load can be understood as a device used to test the function and wiring accuracy of the control cabinet under test. For example, the test load can be a fan or other equipment. The test load can also be a sensor or other equipment used to detect the function and wiring accuracy of the control cabinet under test. This disclosure does not specifically limit the type and category of the test load. Any equipment capable of detecting the function and wiring accuracy of the control cabinet under test is within the protection scope of this application.

[0033] Here, the connection device enables communication between the test load and the control cabinet under test. Specifically, the connector can be installed on the control cabinet under test, establishing an electrical connection between the connector and the control cabinet. Then, the fixed end of the self-resetting telescopic connection mechanism (i.e., the connector plug) can be connected to the test host via a wire, as shown in the specific connection diagram. Figure 3 As shown.

[0034] As described above, in this embodiment of the disclosure, a self-resetting telescopic connecting mechanism (as described above) is used. Figure 2 The connection device shown enables a quick connection between the test host and the connector (e.g., a junction box) of the control cabinet under test, thereby achieving a physical connection between the test host and the control cabinet under test. This connection method avoids system misjudgments caused by human wiring errors, ensuring the testing process is unaffected by the skill level of the testing personnel, and effectively improving testing efficiency.

[0035] Here, the signal correspondence is used to indicate the correspondence between each connection position of the connector and the input / output signals of the control cabinet under test. Each pin of the connector plug in the connector is a connection position. By establishing this signal correspondence, the type of signal corresponding to each connection position of the connector can be made consistent with the type of each input / output signal of the control cabinet under test.

[0036] S103. Send the target control command to the control cabinet under test.

[0037] After establishing the signal correspondence described above, the test host can send a target control command to the control cabinet under test. This target control command is used to control the control cabinet under test to perform a corresponding control action. For example, the target control command can be used to control the control cabinet under test to perform the control action of starting the fan. This disclosure does not specifically limit the type and content of the target control command, but only to the extent that it can be implemented.

[0038] S105. Based on the signal correspondence, determine the target action signal in the test load that matches the target control command.

[0039] After sending the target control command to the control cabinet under test, the wiring position in the control cabinet that reflects the control action can be determined. Then, based on the wiring position and signal correspondence, the target action signal in the test load that matches the target control command can be determined.

[0040] In practice, based on the signal correspondence, the connection position corresponding to the wiring position can be determined among the multiple connection positions of the connection device; then, based on the electrical signal output from the corresponding connection position, the target action signal matching the target control command in the test load can be determined.

[0041] S107. Verify the control cabinet under test based on the target action signal.

[0042] After the target action signal is determined, the function and wiring accuracy of the control cabinet under test can be verified based on the target action signal, thereby obtaining the verification result of the control cabinet under test.

[0043] In this embodiment of the disclosure, a communication connection can be established between the test load and the control cabinet under test (DUT). Through this communication connection, the DUT can control the test load to perform corresponding actions based on control commands. After establishing the communication connection between the DUT and the DUT, a signal correspondence can be established between each connection position of the connection device and the input / output signals of the DUT. Then, a target control command can be sent to the DUT, and based on the aforementioned signal correspondence, a target action signal in the test load that matches the target control command can be determined. Subsequently, the DUT can be verified based on this target action signal.

[0044] In the above embodiments, since the test load and the control cabinet under test are connected by a connecting device, the connection method between the test load and the control cabinet under test can be simplified, thereby shortening the connection time between the test load and the control cabinet under test. Furthermore, after detecting the signal correspondence, the target action signal matching the target control command is determined based on this signal correspondence, and the control cabinet under test is then verified based on this target action signal. This method can further improve the verification efficiency of the control cabinet under test, thereby solving the problem of low control cabinet detection efficiency caused by wiring errors between the test load and the control cabinet in the prior art.

[0045] The above steps will be described in detail below with reference to specific implementation methods.

[0046] As described above, in this embodiment, firstly, the fixed end of the self-resetting telescopic connection mechanism is electrically connected to the test host via a wire; then, the self-resetting telescopic probe of the self-resetting telescopic connection mechanism is inserted into the socket of the connector (i.e., power strip) of the control cabinet under test, thereby realizing the circuit connection between the test host and the control cabinet under test. Next, the signal correspondence between the various connection positions of the connection device and the input / output signals of the control cabinet under test can be established.

[0047] In an optional implementation, step S101 above establishes the signal correspondence between each connection position of the connection device and the input / output signals of the control cabinet under test, specifically including the following steps:

[0048] Step S1011: Determine the signal type of the signal output from each wiring position in the control cabinet under test;

[0049] Step S1012: Based on the signal category, calibrate the signals at each connection position of the connection device to establish the signal correspondence.

[0050] As described above, each wiring position (also known as an external signal) on the power strip of the control cabinet under test has a specific purpose, and the connection relationship between the self-resetting telescopic connection mechanism and the test host remains fixed. This can be used as a benchmark to establish the signal correspondence. The signal type of the external signal (input or output, voltage, current, or switching quantity) is calibrated, and based on this signal type, the corresponding connection position in the self-resetting telescopic connection mechanism of the power strip hardware connection is calibrated, thereby ensuring that the signal type of each connection position in the self-resetting telescopic connection mechanism is the same as the signal type of the connected wiring position in the power strip.

[0051] Here, the signal types at each connection point in the self-resetting telescopic connection mechanism can be programmed to be the same as the signal types at the corresponding wiring positions in the power strip. A line switching device can be installed between the test host and the self-resetting telescopic connection mechanism to establish the aforementioned signal correspondence. Specifically, the signal categories and uses of each wiring position in the power strip of the control cabinet under test can be pre-programmed. Then, the test host sends this programming to the line switching device, thereby ensuring that the definitions of the corresponding pins in the test host are consistent with the definitions of the corresponding pins in the control cabinet under test.

[0052] Based on this, the signal category of the output signal at each wiring position in the control cabinet under test can be determined. For example, this signal category can be various types of signals such as voltage signals, current signals, and switching signals. Then, based on the signal category of each wiring position, the signal category and purpose of each wiring position in the power strip of the control cabinet under test can be programmed, and this programming can be sent to the line switching device. After receiving the programming, the line switching device can calibrate the signals at each connection position of the connection device based on the programmed content, thereby establishing the signal correspondence.

[0053] In the above embodiments, by establishing signal correspondence, the verification efficiency of the control cabinet under test can be improved, thereby solving the problem of low detection efficiency of control cabinet caused by wiring errors between the test load and the control cabinet in the prior art.

[0054] In an optional implementation, step S103 above, which sends a target control command to the control cabinet under test, specifically includes the following steps:

[0055] Step S1031: When there are multiple test loads, determine the test order of the multiple test loads and the test action of each test load;

[0056] Step S1032: In accordance with the test sequence, send a target control command that matches the test action to the control cabinet under test.

[0057] In this embodiment of the disclosure, after establishing the signal correspondence described above, the test host can send a target control command to the control cabinet under test, so that the control cabinet under test can be controlled to perform a corresponding control action. This control action is the action of controlling the test load to perform a corresponding action.

[0058] If there are multiple test loads on the control cabinet under test, then the matching target control commands need to be sent to the control cabinet under test in the order of the test of the multiple test loads.

[0059] Specifically, the test sequence of multiple test loads and the test action of each test load can be determined, where the test action can be understood as the control action of the control cabinet under test described above.

[0060] Here, the test order can be determined in at least one of the following ways:

[0061] The testing sequence of multiple test loads can be determined based on the functions of the control cabinet under test.

[0062] The test order of multiple test loads can be determined based on the load type of the test load;

[0063] The test sequence of multiple test loads can be determined based on the test location of the control cabinet under test.

[0064] After determining the test sequence, the target control command that matches each test load can be determined, and the matching target control command can be sent to the control cabinet under test in accordance with the test sequence.

[0065] Here, target control commands matching the test actions can be sent to the control cabinet under test sequentially according to the test order; or, after each target control command is sent, the next target control command can be sent to the control cabinet under test after the target action signal corresponding to the target control command is detected.

[0066] After sending the target control command to the control cabinet under test, the target action signal in the test load that matches the target control command can be determined based on the signal correspondence.

[0067] Here, it is possible to send all target control commands to the control cabinet under test, and receive the target action signal corresponding to each target control command in sequence. Alternatively, after each target control command is sent, the target action signal corresponding to that target control command can be received, and the next target control command can be sent, until all target control commands have been sent.

[0068] Here, it is possible to set up automatic sending of target control commands to the control cabinet under test, or it is possible to set up manual sending of target control commands to the control cabinet under test. This disclosure does not make specific limitations on this.

[0069] In an optional implementation, step S105 above, based on the signal correspondence, determines the target action signal in the test load that matches the target control command, including:

[0070] Step S1051: Based on the signal correspondence, determine at least one target pin in the test load that matches the target control command;

[0071] Step S1052: Determine the pin output signal for each target pin;

[0072] Step S1053: Determine the target action signal based on the pin output signal.

[0073] In this embodiment of the disclosure, after sending the target control command to the control cabinet under test, firstly, the wiring position in the control cabinet under test used to perform the corresponding control action can be determined. Then, based on the signal correspondence, the connection position corresponding to the wiring position among multiple connection positions of the connecting device can be determined. At this time, the connection position can be determined as at least one target pin described in the above steps.

[0074] Next, based on the electrical signals output by each target pin, the target action signal in the test load that matches the target control command can be determined.

[0075] In practice, after identifying at least one target pin that matches the target control command, the test host can send a switching command to the line switching device to switch to connecting to each target pin. After switching to connecting to each target pin, the test host can obtain the target action signal by acquiring the electrical signal output by each target pin and processing the signal.

[0076] In the above embodiments, the method of determining the target action signal that matches the target control command through the signal correspondence and verifying the control cabinet under test based on the target action signal can further improve the verification efficiency of the control cabinet under test, thereby solving the problem of low detection efficiency of control cabinet caused by wiring errors between the test load and the control cabinet in the prior art.

[0077] In an optional implementation, step S107 verifies the control cabinet under test based on the action signal, specifically including the following steps:

[0078] Step S1071: Determine whether the target action indicated by the target action signal matches the expected action indicated by the target control command;

[0079] Step S1072: If it is determined that the target action and the expected action match, the test control cabinet is verified as passed.

[0080] In this embodiment of the disclosure, the expected action signal of the test load can be determined; wherein, the expected action signal is used to indicate the action signal output by the signal terminal of the test load when the control cabinet under test is operating normally; for example, a target control command can be determined as the expected action signal. Then, the consistency between the expected action signal and the target action signal is verified to obtain a verification result; based on the verification result, it is determined whether the target action and the expected action match.

[0081] Here, if the verification result shows that the target action and the expected action match, then the test on the control cabinet under test is deemed to have passed; if the verification result shows that the target action and the expected action do not match, then the test on the control cabinet under test is deemed to have failed.

[0082] For example, assuming the test load is a fan, the auxiliary contacts of the AC contactor controlling the fan's start are connected to the terminal block of the control cabinet under test via a self-resetting telescopic connection mechanism. After the test host sends the target control command to start the fan in the control cabinet under test, it checks whether the corresponding target pins act according to the control command. If they match, it's normal; otherwise, it's considered abnormal. Here, the pin output signals of the target pins can be controlled and checked sequentially to see if they match the expected action signals. If they match, it's normal; otherwise, it's considered abnormal. Through the above processing method, the correctness of the control cabinet's wiring and the functionality of its electrical components can be tested.

[0083] After obtaining the test results, if multiple functions of the control cabinet under test need to be tested, the test result for each function can be determined, for example, indicating a pass or a fail result. Furthermore, for functions that fail the test, the reasons for the failure can be analyzed. Specifically, the target action signal can be compared with a fault database. If a matching fault action signal is found in the fault database, the cause of the failure is determined based on the fault action signal. Here, the fault database can contain at least one fault action signal and the corresponding fault cause for each fault action signal.

[0084] In the above embodiments, since the test load and the control cabinet under test are connected by a connecting device, the connection method between the test load and the control cabinet under test can be simplified, thereby shortening the connection time between the test load and the control cabinet under test. Furthermore, after detecting the signal correspondence, the target action signal matching the target control command is determined based on this signal correspondence, and the control cabinet under test is then verified based on this target action signal. This method can further improve the verification efficiency of the control cabinet under test, thereby solving the problem of low control cabinet detection efficiency caused by wiring errors between the test load and the control cabinet in the prior art.

[0085] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0086] Based on the same inventive concept, this disclosure also provides a control cabinet detection device corresponding to the control cabinet detection method. Since the principle of the device in this disclosure for solving the problem is similar to the control cabinet detection method described above in this disclosure, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be described again.

[0087] Reference Figure 4 The diagram shown is a schematic of a control cabinet detection device provided in an embodiment of this disclosure. The device includes: an establishment unit 10, a sending unit 20, a determination unit 30, and a verification unit 40; wherein,

[0088] Establishment unit 10 is used to establish the signal correspondence between each connection position of the connection device and the input and output signals of the control cabinet under test; wherein, the connection device is used to realize the communication connection between the test load and the control cabinet under test;

[0089] The sending unit 20 is used to send target control commands to the control cabinet under test;

[0090] The determining unit 30 is used to determine, based on the signal correspondence, the target action signal in the test load that matches the target control command;

[0091] Verification unit 40 is used to verify the control cabinet under test based on the target action signal.

[0092] By establishing a communication connection between the test load and the control cabinet under test (DUT) through a connecting device, the connection method between the test load and the DUT can be simplified, thereby shortening the connection time. Furthermore, after detecting the signal correspondence, the target action signal matching the target control command is determined based on this correspondence. The DUT is then verified based on this target action signal, further improving the verification efficiency of the DUT. This solves the problem of low control cabinet testing efficiency caused by wiring errors between the test load and the control cabinet in existing technologies.

[0093] In one possible implementation, the verification unit is further configured to: determine whether the target action indicated by the target action signal matches the expected action indicated by the target control command; and, if the target action and the expected action match, determine that the verification of the control cabinet under test has passed.

[0094] In one possible implementation, the verification unit is further configured to: determine the expected action signal of the test load; wherein the expected action signal is used to indicate the action signal output by the signal terminal of the test load when the control cabinet under test is operating normally; verify the consistency between the expected action signal and the target action signal to obtain a verification result; and determine whether the target action and the expected action match based on the verification result.

[0095] In one possible implementation, the sending unit is further configured to: determine the test order of the multiple test loads and the test action of each test load when there are multiple test loads; and send a target control command matching the test action to the control cabinet under test according to the test order.

[0096] In one possible implementation, the determining unit is further configured to: determine at least one target pin in the test load that matches the target control command based on the signal correspondence; determine the pin output signal of each target pin; and determine the target action signal based on the pin output signal.

[0097] In one possible implementation, the establishment unit is further configured to: determine the signal category of the signal output at each wiring position in the control cabinet under test; and calibrate the signals at each connection position of the connection device based on the signal category, so as to establish the signal correspondence.

[0098] Based on the same inventive concept, this disclosure also provides a control cabinet testing system corresponding to the control cabinet testing method. For example... Figure 5 The diagram shown is a structural schematic of a control cabinet detection system provided in a specific embodiment of the present invention. Figure 5 As shown, the control cabinet testing system includes: a test host 100, a test load 200, and a connection device 300.

[0099] like Figure 5 As shown, the test host 100 is communicatively connected to the control cabinet under test 400, the connection device 300 is communicatively connected to the test load 200 and the control cabinet under test 400 respectively, and the test load 200 is communicatively connected to the test host.

[0100] In this embodiment of the disclosure, the test host 100 is configured to establish a signal correspondence between each connection position of the connection device and the input / output signals of the control cabinet under test; wherein the connection device is used to realize the communication connection between the test load and the control cabinet under test; to send a target control command to the control cabinet under test, and to determine a target action signal in the test load that matches the target control command based on the signal correspondence; and to verify the control cabinet under test based on the target action signal.

[0101] Here, the signal correspondence is used to indicate the correspondence between each connection position of the connector and the input / output signals of the control cabinet under test. Each pin of the connector plug in the connector is a connection position. By establishing this signal correspondence, the type of signal corresponding to each connection position of the connector can be made consistent with the type of each input / output signal of the control cabinet under test.

[0102] In this embodiment of the disclosure, a self-resetting telescopic connection mechanism (as described above) is used. Figure 2 The connection device shown enables a quick connection between the test host and the connector (e.g., a junction box) of the control cabinet under test, thereby achieving a physical connection between the test host and the control cabinet under test. This connection method avoids system misjudgments caused by human wiring errors, ensuring the testing process is unaffected by the skill level of the testing personnel, and effectively improving testing efficiency.

[0103] In one alternative implementation, such as Figure 5 As shown, the control cabinet testing system also includes: a line switching device 600; wherein the line switching device is configured to communicate with the connection plug of the connection device and the test host.

[0104] The test host is configured to establish a signal correspondence between the connection positions of the connection device and the input / output signals of the control cabinet under test through the line switching device.

[0105] As described above, each wiring position (also known as an external signal) on the power strip of the control cabinet under test has a specific purpose, and the connection relationship between the self-resetting telescopic connection mechanism and the test host remains fixed. This can be used as a benchmark to establish the signal correspondence. The signal type of the external signal (input or output, voltage, current, or switching quantity) is calibrated, and based on this signal type, the corresponding connection position in the self-resetting telescopic connection mechanism of the power strip hardware connection is calibrated, thereby ensuring that the signal type of each connection position in the self-resetting telescopic connection mechanism is the same as the signal type of the connected wiring position in the power strip.

[0106] Here, the signal types at each connection point in the self-resetting telescopic connection mechanism can be programmed to be the same as the signal types at the corresponding wiring positions in the power strip. A line switching device can be installed between the test host and the self-resetting telescopic connection mechanism to establish the aforementioned signal correspondence. Specifically, the signal categories and uses of each wiring position in the power strip of the control cabinet under test can be pre-programmed. Then, the test host sends this programming to the line switching device, thereby ensuring that the definitions of the corresponding pins in the test host are consistent with the definitions of the corresponding pins in the control cabinet under test.

[0107] In this embodiment of the disclosure, when a target action signal is determined, the test host can send a switching command to the line switching device to switch to the target pin described above. After switching to the target pin, the signal processor can acquire the electrical signal output by each target pin, process the electrical signal, and then send the obtained target action information to the test host.
