[0002] Due to the special use environment of aviation oil-cooled motors, there are many types of cooling oil used in simulation tests.

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0047] Figure 1 is a structural block diagram of an oil product matching system provided by an embodiment of the present invention, see Figure 1 The oil matching system includes a test bench 10 and a plurality of oil tanks 20. An aviation socket 210 is provided on the oil tank 20. The connection modes of the pins of the aviation socket 210 in different oil tanks 20 are different, and the oil types in different oil tanks 20 are different. The test bench 10 is electrically connected to the oil-cooled motor to be tested and the aviation socket 210, respectively, and is used to determine the connection mode of the pins of the corresponding aviation socket 210 according to the voltage information of the pins of the aviation socket 210 obtained, and determine the first oil product information of the corresponding oil tank 20 according to the connection mode, and obtain the second oil product information of the oil-cooled motor to be tested, and determine whether to perform the durability test according to the first oil product information and the second oil product information.

[0048] Specifically, an oil-cooled motor is a motor that uses cooling oil as a cooling medium. The cooling oil is sprayed directly into the motor or onto the windings to remove heat and reduce the motor temperature. Due to the special use environment of aviation oil-cooled motors, there are many types of cooling oils to be tested when performing durability tests on oil-cooled motors used in the aviation field. Therefore, before performing a durability test on an oil-cooled motor, it is necessary to first distinguish the type of cooling oil in the corresponding oil tank 20, and then match the type of cooling oil in the oil tank 20 with the required oil type of the oil-cooled motor to be tested. For example, the required oil type of the oil-cooled motor to be tested is type A cooling oil, type B cooling oil, type C cooling oil or type D cooling oil, etc. When the required oil type of the oil-cooled motor to be tested is type A cooling oil, the corresponding cooling oil to be added must also be type A cooling oil. Similarly, when the required oil type of the oil-cooled motor to be tested is type B cooling oil, the corresponding cooling oil added must also be type B cooling oil, ... and so on. That is, the oil-cooled motor durability test will only be started when the required oil type of the oil-cooled motor to be tested is consistent with the oil type of the cooling oil in the oil tank 20.

[0049] In the prior art, the oil type of the cooling oil in the oil tank is usually identified manually, and it is manually confirmed that the required oil type of the oil-cooled motor to be tested is consistent with the oil type of the cooling oil in the oil tank. However, the manual identification of the oil type is slow and it is easy to make mistakes in identifying the oil type of the cooling oil in the oil tank, and fill the oil type that does not match the oil-cooled motor to be tested, thereby delaying the endurance test cycle and erroneous measurement results.

[0050] To this end, the embodiment of the present invention sets pins of different connection modes for the aviation sockets 210 in different fuel tanks 20 to correspond to cooling oils of different oil types. Exemplarily, the aviation socket 210 includes a plurality of pins, and there are multiple connection modes between different pins, and the voltage information between the lower pins of different connection modes is also different, and then the connection mode of the pins of the aviation socket 210 in the fuel tank 20, the voltage information between the pins, and the oil type of the cooling oil in the fuel tank 20 are made to correspond. For example, the connection mode of the pins in the aviation socket 210 includes a first connection mode, a second connection mode, and a third connection mode, and the oil type of the cooling oil in the fuel tank 20 includes type A cooling oil, type B cooling oil, and type C cooling oil. The voltage information under the first connection mode corresponds to type A cooling oil, the type B cooling oil corresponds to the voltage information under the second connection mode, and the type C cooling oil corresponds to the voltage information under the third connection mode. In this way, when the test bench 10 is electrically connected to the aviation socket 210 of any fuel tank 20, the test bench 10 can determine the connection mode of the pins in the corresponding aviation socket 210 by detecting the voltage information of the aviation socket 210, and determine the first oil product information of the corresponding fuel tank 20 through the connection mode. For example, when the test bench 10 determines that the connection mode is the first connection mode according to the voltage information of the corresponding aviation socket 210, the first oil product information in the fuel tank 20 can be determined as type A cooling oil according to the first connection mode, when the test bench 10 determines that the connection mode is the second connection mode according to the voltage information of the corresponding aviation socket 210, the first oil product information in the fuel tank 20 can be determined as type B cooling oil according to the second connection mode, and when the test bench 10 determines that the connection mode is the third connection mode according to the voltage information of the corresponding aviation socket 210, the first oil product information in the fuel tank 20 can be determined as type C cooling oil according to the third connection mode. Afterwards, the test bench 10 also obtains the required oil type of the oil-cooled motor to be tested, that is, the second oil information, and determines whether to perform a durability test based on the required oil type of the oil-cooled motor to be tested (the second oil information) and the oil type of the cooling oil in the oil tank 20 (the first oil information). For example, the oil-cooled motor durability test will only be started when the required oil type of the oil-cooled motor to be tested is consistent with the oil type of the cooling oil in the oil tank 20. In this way, since the first oil information in the oil tank 20 and whether to perform a durability test (whether the first oil information and the second oil information are consistent) are both determined by the test bench 10, the time for manual judgment is saved, and manual identification errors are avoided, and the situation of filling an oil type that does not match the oil-cooled motor to be tested is improved, thereby improving the test efficiency and test accuracy.

[0051] It should be noted that Figure 1The example of three different oil tanks 20 is merely used for illustration, but is not intended to be limiting. In other embodiments, other numbers of oil tanks, i.e. other numbers of oil types, may be provided, and those skilled in the art may set the same as required.

[0052] In summary, the oil matching system in the embodiment of the present invention includes a test bench and multiple oil tanks. An aviation socket is provided on the oil tank, and the connection methods of the pins of the aviation sockets in different oil tanks are different, and the oil types in different oil tanks are different. The test bench is electrically connected to the oil-cooled motor to be tested and the aviation socket, respectively, and is used to determine the connection method of the pins of the corresponding aviation socket according to the voltage information of the pins of the aviation socket obtained, and determine the first oil product information of the corresponding oil tank according to the connection method, and obtain the second oil product information of the oil-cooled motor to be tested, and determine whether to perform a durability test according to the first oil product information and the second oil product information. In this way, since the connection methods of the pins of the aviation sockets in different fuel tanks are different, and the oil types in different fuel tanks are different, when the test bench is connected to the aviation socket of the fuel tank, the first oil product information of the corresponding fuel tank can be determined through the connection method, and then the test bench automatically determines whether the second oil product information of the oil-cooled motor to be tested matches the first oil product information in the connected fuel tank. Since the first oil product information in the fuel tank and whether to perform a durability test are both determined by the test bench, the time for manual judgment is saved, and at the same time, manual identification errors are avoided, and the situation of filling the oil type that does not match the oil-cooled motor to be tested is avoided, thereby improving the test efficiency and test accuracy.

[0053] Optional, Figure 2 Schematic diagram of the structure of an oil matching system provided by an embodiment of the present invention. Figure 2 The aviation socket 210 includes at least three pins, and the aviation sockets 210 in different fuel tanks 20 short-circuit different pins.

[0054] For example, Figure 2In the illustrated embodiment, the oil types in different fuel tanks 20 are distinguished by short-circuiting different pins in different aviation sockets 210. Specifically, short-circuiting two of the multiple pins in the aviation socket 210 is used as a connection method. For example, the aviation socket 210 includes three pins, namely the first pin T1, the second pin T2, and the third pin T3. Among them, short-circuiting the first pin T1 and the second pin T2 is used as the first connection method, and short-circuiting the first pin T1 and the third pin T3 is used as the second connection method. Then, when the test bench 10 is electrically connected to the aviation socket 210, if it is detected that there is a voltage between the first pin T1 and the second pin T2, and there is no voltage between the first pin T1 and the third pin T3, it is confirmed that the connection method of the corresponding aviation socket 210 is the first connection method. If it is detected that there is no voltage between the first pin T1 and the second pin T2, but there is voltage between the first pin T1 and the third pin T3, it is confirmed that the connection mode of the corresponding aviation socket 210 is the second connection mode. In this way, different connection modes are distinguished by the presence of voltage between the two short-circuited pins, thereby ensuring that the identification method of the first oil product information in different fuel tanks 20 is simple.

[0055] Based on the above embodiments, continue to refer to Figure 2, at least three pins include a first pin T1, a second pin T2, a third pin T3 and a fourth pin T4. The multiple oil tanks 20 include a first oil tank 201, a second oil tank 202 and a third oil tank 203. Different oil tanks 20 correspond to cooling oils of different oil types. Among them, the oil type of the cooling oil in the first oil tank 201 is the first oil, that is, type A cooling oil. The oil type of the cooling oil in the second oil tank 202 is the second oil, that is, type B cooling oil. The oil type of the cooling oil in the third oil tank 203 is the third oil, that is, type C cooling oil. On this basis, the first pin T1 and the second pin T2 of the aviation socket 210 in the first oil tank 201 are short-circuited as the first connection mode, that is, the first connection mode corresponds to type A cooling oil. The first pin T1 and the third pin T3 of the aviation socket 210 in the second oil tank 202 are short-circuited as the second connection mode, that is, the second connection mode corresponds to type B cooling oil. The first pin T1 and the fourth pin T4 of the aviation socket 210 in the third oil tank 203 are short-circuited as the third connection mode, that is, the third connection mode corresponds to the C-type cooling oil. In this way, when the test bench 10 is electrically connected to one of the oil tanks 20, if a voltage is detected between the first pin T1 and the second pin T2, it is determined that the connection mode of the corresponding aviation socket 210 is the first connection mode, that is, the oil tank 20 is the first oil tank 201, and the cooling oil therein is the A-type cooling oil. If a voltage is detected between the first pin T1 and the third pin T3, it is determined that the connection mode of the corresponding aviation socket 210 is the second connection mode, that is, the oil tank 20 is the second oil tank 202, and the cooling oil therein is the B-type cooling oil. If a voltage is detected between the first pin T1 and the fourth pin T4, it is determined that the connection mode of the corresponding aviation socket 210 is the third connection mode, that is, the oil tank 20 is the third oil tank 201, and the cooling oil therein is the C-type cooling oil. In this way, by matching the oil type of the cooling oil with the oil tank 20 and the connection method, the identification method of the first oil product information in the corresponding oil tank 20 is ensured to be simple, and the accuracy of the first oil product information identification is improved, thereby improving the test efficiency and test accuracy.

[0056] Optionally, based on the above embodiment, the first pin T1 can be electrically connected to the power supply end, and the power supply end can provide a 24V voltage. Then, when the voltage between the first pin T1 and the second pin T2 is detected to be 24V, it is determined that the connection mode of the corresponding aviation socket 210 is the first connection mode, that is, the fuel tank 20 is the first fuel tank 201, and the cooling oil therein is type A cooling oil. If the voltage between the first pin T1 and the third pin T3 is detected to be 24V, it is determined that the connection mode of the corresponding aviation socket 210 is the second connection mode, that is, the fuel tank 20 is the second fuel tank 202, and the cooling oil therein is type B cooling oil. If the voltage between the first pin T1 and the fourth pin T4 is detected to be 24V, it is determined that the connection mode of the corresponding aviation socket 210 is the third connection mode, that is, the fuel tank 20 is the third fuel tank 203, and the cooling oil therein is type C cooling oil.

[0057] Optional, continue to see Figure 2 The test bench 10 includes an interface (not shown in the figure), which is detachably connected to one of the multiple aviation sockets 210. Specifically, when matching oil products, the test bench 10 can only be electrically connected to the aviation socket 210 of one of the oil tanks 20 at a time. When it is determined that the second oil product information of the oil-cooled motor to be tested is consistent with the first oil product information in the corresponding oil tank 20, the corresponding oil tank 20 is filled with oil for the oil-cooled motor to be tested, thereby starting the durability test. If the second oil product information of the oil-cooled motor to be tested is inconsistent with the first oil product information in the corresponding oil tank 20, the test bench 10 is disconnected from the aviation socket 210 being connected, so that the corresponding oil tank 20 is disconnected from the oil-cooled motor to be tested, and the oil-cooled motor to be tested is not subjected to the durability test. After that, the oil tank 20 is replaced and re-matched until the second oil product information of the oil-cooled motor to be tested is consistent with the first oil product information in the corresponding electrically connected oil tank 20, thereby further ensuring the accuracy of the durability test.

[0058] Optionally, based on the above embodiment, continue to refer to Figure 2 The oil product matching system further includes a display unit (not shown in the figure), which is electrically connected to the test bench 10 and is used to display the first oil product information of the corresponding electrically connected oil tank 20. Specifically, after the test bench 10 determines the first oil product information of the corresponding electrically connected oil tank 20, it also sends a control signal to the display unit so that the display unit displays the corresponding first oil product information, which is convenient for the staff to check the final matching result. In this way, the accuracy of the durability test is further guaranteed through the dual judgment of the test bench 10 and the staff.

[0059] Based on the same inventive concept, an embodiment of the present invention further provides an oil matching method. Figure 3 Schematic diagram of a flow chart of an oil product matching method provided by an embodiment of the present invention. Figure 1 and Figure 3, the oil matching method includes:

[0060] S110: Obtain voltage information of the pins of the aviation socket.

[0061] Specifically, the aviation socket 210 includes multiple pins, and there are multiple connection methods between different pins, and the voltage information between the lower pins of different connection methods is also different. In this way, the test bench 10 is electrically connected to the aviation socket 210, and then the voltage information corresponding to the aviation socket 210 is determined through the test bench 10, so as to identify the connection method of the corresponding aviation socket 210.

[0062] S120: Determine a connection mode of a pin of a corresponding aviation socket according to the voltage information, and determine first oil product information of a corresponding oil tank according to the connection mode.

[0063] Exemplarily, the connection mode of the pins of the aviation socket 210 in the fuel tank 20, the voltage information between the pins, and the oil type of the cooling oil in the fuel tank 20 are matched. For example, the connection mode of the pins in the aviation socket 210 includes a first connection mode, a second connection mode, and a third connection mode, and the oil type of the cooling oil in the fuel tank 20 includes type A cooling oil, type B cooling oil, and type C cooling oil. The voltage information under the first connection mode is matched with type A cooling oil, the type B cooling oil is matched with the voltage information under the second connection mode, and the type C cooling oil is matched with the voltage information under the third connection mode. In this way, when the test bench 10 is electrically connected to the aviation socket 210 of any fuel tank 20, the test bench 10 can determine the connection mode of the pins in the corresponding aviation socket 210 by detecting the voltage information of the aviation socket 210, and determine the first oil product information of the corresponding fuel tank 20 through the connection mode. For example, when the test bench 10 determines that the connection mode is the first connection mode according to the voltage information of the corresponding aviation socket 210, the first oil product information in the oil tank 20 can be determined as type A cooling oil according to the first connection mode; when the connection mode is determined to be the second connection mode according to the voltage information of the corresponding aviation socket 210, the first oil product information in the oil tank 20 can be determined as type B cooling oil according to the second connection mode; and when the connection mode is determined to be the third connection mode according to the voltage information of the corresponding aviation socket 210, the first oil product information in the oil tank 20 can be determined as type C cooling oil according to the third connection mode.

[0064] S130, obtaining second oil product information of the oil-cooled motor to be tested, and determining whether to perform a durability test according to the first oil product information and the second oil product information.

[0065] The test bench 10 also obtains the required oil type of the oil-cooled motor to be tested, that is, the second oil information, and determines whether to perform the durability test based on the required oil type of the oil-cooled motor to be tested (the second oil information) and the oil type of the cooling oil in the oil tank 20 (the first oil information). For example, the oil-cooled motor durability test will only be started when the required oil type of the oil-cooled motor to be tested is consistent with the oil type of the cooling oil in the oil tank 20. In this way, since the first oil information in the oil tank 20 and whether to perform the durability test (whether the first oil information and the second oil information are consistent) are both determined by the test bench 10, the time for manual judgment is saved, and manual identification errors are avoided, and the situation of filling the oil type that does not match the oil-cooled motor to be tested is improved, thereby improving the test efficiency and test accuracy.

[0066] In summary, the embodiment of the present invention obtains the voltage information of the pin of the aviation socket, determines the connection mode of the pin of the corresponding aviation socket according to the voltage information, and determines the first oil product information of the corresponding oil tank according to the connection mode. Then, the second oil product information of the oil-cooled motor to be tested is obtained, and whether to perform the durability test is determined according to the first oil product information and the second oil product information. In this way, since the connection modes of the pins of the aviation sockets in different oil tanks are different, and the oil types in different oil tanks are different, when the test bench is connected to the aviation socket of the oil tank, the first oil product information of the corresponding oil tank can be determined by the connection mode, and then the test bench automatically determines whether the second oil product information of the oil-cooled motor to be tested matches the first oil product information in the connected oil tank. Since the first oil product information in the oil tank and whether to perform the durability test are all determined by the test bench, the time of manual judgment is saved, and at the same time, manual identification errors are avoided, and the situation of filling the oil type that does not match the oil-cooled motor to be tested is improved, thereby improving the test efficiency and the accuracy of the test.

[0067] Optional, Figure 4 FIG. 1 is a flow chart of another oil product matching method provided by an embodiment of the present invention. Figure 2 and Figure 4 , the oil matching method includes:

[0068] S210, obtaining voltage information between different pins of the aviation socket in the fuel tank.

[0069] By short-circuiting different pins in different aviation sockets 210, the oil types in different fuel tanks 20 can be distinguished. Specifically, short-circuiting two of the multiple pins in the aviation socket 210 is used as a connection method. For example, the aviation socket 210 includes four pins, namely the first pin T1, the second pin T2, the third pin T3 and the fourth pin T4. Among them, short-circuiting the first pin T1 and the second pin T2 is used as the first connection method, short-circuiting the first pin T1 and the third pin T3 is used as the second connection method, and short-circuiting the first pin T1 and the third pin T4 is used as the third connection method. On this basis, the test bench 10 is electrically connected to the aviation socket 210 to obtain the corresponding voltage information.

[0070] S220: Determine a connection mode of a pin of a corresponding aviation socket according to the voltage information, and determine first oil product information of a corresponding oil tank according to the connection mode.

[0071] When the test bench 10 is electrically connected to the aviation socket 210, if there is a voltage between the first pin T1 and the second pin T2 of the aviation socket 210 in the fuel tank 20, the connection mode of the aviation socket 210 is determined to be the first connection mode. If there is a voltage between the first pin T1 and the third pin T3 of the aviation socket 210 in the fuel tank 20, the connection mode of the aviation socket 210 is determined to be the second connection mode. If there is a voltage between the first pin T1 and the fourth pin T4 of the aviation socket 210 in the fuel tank 20, the connection mode of the aviation socket 210 is determined to be the third connection mode. In this way, different connection modes are distinguished by the presence of voltage between the two short-circuited pins, ensuring that the identification method of the first oil product information in different fuel tanks 20 is simple.

[0072] In addition, the test bench 10 presets a first correspondence between the connection mode and the oil type, and determines the first oil product information of the corresponding oil tank according to the connection mode and the first correspondence. Specifically, when the test bench 10 is electrically connected to one of the oil tanks 20, if a voltage is detected between the first pin T1 and the second pin T2, it is determined that the connection mode of the corresponding aviation socket 210 is the first connection mode, and the oil tank 20 is determined to be the first oil tank 201 according to the first connection mode and the first correspondence, and the cooling oil therein is type A cooling oil. If a voltage is detected between the first pin T1 and the third pin T3, it is determined that the connection mode of the corresponding aviation socket 210 is the second connection mode, and the oil tank 20 is determined to be the second oil tank 202 according to the second connection mode and the first correspondence, and the cooling oil therein is type B cooling oil. If a voltage is detected between the first pin T1 and the fourth pin T4, it is determined that the connection mode of the corresponding aviation socket 210 is the third connection mode, and the oil tank 20 is determined to be the third oil tank 201 according to the third connection mode and the first correspondence, and the cooling oil therein is type C cooling oil. In this way, by matching the oil type of the cooling oil with the oil tank 20 and the connection method, the identification method of the first oil product information in the corresponding oil tank 20 is ensured to be simple, and the accuracy of the first oil product information identification is improved, thereby improving the test efficiency and test accuracy.

[0073] S230. When the oil type of the first oil product information is consistent with the oil type of the second oil product information, the oil tank is filled with oil for the oil-cooled motor to be tested, and the oil-cooled motor to be tested starts the durability test; and when the oil type of the first oil product information is inconsistent with the oil type of the second oil product information, the oil tank is disconnected from the oil-cooled motor to be tested, and the oil-cooled motor to be tested stops the durability test.

[0074] Specifically, when performing oil matching, the test bench 10 can only be electrically connected to the aviation socket 210 of one of the oil tanks 20 at a time. When it is determined that the second oil product information of the oil-cooled motor to be tested is consistent with the first oil product information in the corresponding oil tank 20, the corresponding oil tank 20 is filled with oil for the oil-cooled motor to be tested, thereby starting the durability test. If the second oil product information of the oil-cooled motor to be tested is inconsistent with the first oil product information in the corresponding oil tank 20, the test bench 10 is disconnected from the aviation socket 210 being connected, so that the corresponding oil tank 20 is disconnected from the oil-cooled motor to be tested, and the oil-cooled motor to be tested is not subjected to the durability test. After that, the oil tank 20 is replaced and re-matched until the second oil product information of the oil-cooled motor to be tested is consistent with the first oil product information in the corresponding electrically connected oil tank 20, further ensuring the accuracy of the durability test.

[0075] In summary, the embodiment of the present invention obtains voltage information between different pins of the aviation socket in the fuel tank, determines the connection method of the pins of the corresponding aviation socket according to the voltage information, and determines the first oil product information of the corresponding fuel tank according to the connection method. Then, when the oil type of the first oil product information is consistent with the oil type of the second oil product information, the fuel tank is filled with oil for the oil-cooled motor to be tested, and the oil-cooled motor to be tested starts the durability test; when the oil type of the first oil product information is inconsistent with the oil type of the second oil product information, the fuel tank is disconnected from the oil-cooled motor to be tested, and the oil-cooled motor to be tested stops the durability test, thereby further improving the test efficiency and test accuracy.
