[0038] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0039] A specific embodiment of the utility model discloses an aircraft cable detection device, such as Figure 1 As shown, the aircraft cable detection device includes an MCU, a power supply, a voltage-dividing resistor, a first interface combination, a second interface combination and a switching module;

[0040] The first interface combination and the second interface combination both include a first number of input-output combinations;

[0041] Each input-output combination includes an output interface, an input interface, an input inverter and an output inverter; the output interface is connected to the input end of the output inverter, the input interface is connected to the output end of the input inverter, the output end of the output inverter is connected to the input end of the input inverter, the connection point serves as the external interface of the input-output combination, and the external interface of the input-output combination is connected to the power supply through a voltage-dividing resistor; the input interface and the output interface of each input-output combination are connected to the MCU;

[0042] The adapter module includes a first adapter module and a second adapter module. The external interface of each input-output combination of the first interface combination is connected to one end of the aircraft cable to be detected through the first adapter module, and the external interface of each input-output combination of the second interface combination is connected to the other end of the aircraft cable to be detected through the second adapter module.

[0043] Specifically, Figure 1 As shown, the MCU is connected to the adapter module through the first interface combination and the second interface combination, and the adapter module is connected to both ends of the aircraft cable to be detected through the first adapter module and the second adapter module, so as to detect each cable in the aircraft cable to be detected.

[0044] Specifically, there are various types of aircraft cables. The value of the first number is determined according to the number of cables included in the aircraft cable. The first number should be greater than the maximum value of the number of cables included in the aircraft cable.

[0045] The first interface combination is connected to the first adapter module through the first number of wires, and the second interface combination is connected to the second adapter module through the first number of wires. When the first adapter module and the second adapter module are connected to the aircraft cable to be detected, they need to be reasonably connected according to the actual situation of the type of the aircraft cable to be detected. For example, if there are 4 cables in the aircraft cable to be detected, the first adapter module needs to output 4 wires to connect to one end of the aircraft cable to be detected, and the second adapter module needs to output 4 wires to connect to the other end of the aircraft cable to be detected.

[0046] Specifically, Figure 1As shown, in each input-output combination, the output interface is connected to the input end of the output inverter, the input interface is connected to the output end of the input inverter, the output end of the output inverter is connected to the input end of the input inverter, the connection point serves as the external interface of the input-output combination, and the external interface of the input-output combination is connected to the power supply through a voltage divider resistor, and the input interface and output interface of each input-output combination are connected to the MCU.

[0047] Specifically, Figure 2 As shown, the MCU sends a voltage value to the output inverter through the output interface of each input-output combination, and the voltage value is inverted by the output inverter and output to the detection point on the tested cable; at the same time, the input interface of each input-output combination receives the inverted voltage value of the detection point through the input inverter.

[0048] Specifically, Figure 1 and Figure 2 As shown, the external interface of each input-output combination also needs to be connected to the power supply through a voltage divider resistor, thereby realizing the detection of the aircraft cable to be detected. Preferably, the power supply is a rechargeable lithium battery or a replaceable dry battery, so that it can be reused and save resources.

[0049] like Figure 2 As shown, when a tested cable in the aircraft cable to be tested is tested, U2A and U4A are output inverters, U1A and U3A are input inverters, and the MCU is connected to the first interface combination and the second interface combination through the input interface and the output interface. When the tested cable is tested for conduction, the MCU outputs a positive voltage value through port 1 of U2A, and port 2 of U2A becomes a negative voltage value after inversion. Since port 1 of U1A is connected to port 2 of U2A, port 1 of U1A is also a negative voltage value, and the input of port 2 of U1A is a positive voltage value after inversion. Since a positive value is output to this detection point while the outputs of the other detection points are all negative voltage values, the detection point at the other end of the detected loop outputs a negative voltage value, that is, port 1 of U4A outputs a negative voltage value.

[0050] If the tested cable is open circuit, after the second reversal of U4A and U3A, the input of U3A's port 2 is also a negative voltage value; if the tested cable is open circuit, although the output of U4A's port 1 is a negative voltage value, since U4A's port 2 is also connected to U2A's port 2, U4A is open circuit and does not have a reverse effect. Because U3A's port 1 is connected to U2A's port 2 as a negative voltage value, the input of U3A's port 2 after the reversal is a positive voltage value. That is, by outputting different positive and negative voltage values ​​to the input and output combination through the MCU, the continuity of the tested cable can be determined. When testing the aircraft cable being tested, you only need to set the test sequence to perform continuity detection on all the tested cables of the aircraft cable being tested.

[0051] Preferably, the first adapter module and the second adapter module both include a standard cable, an adapter board and an adapter socket;

[0052] The standard cable includes a first number of connecting wires, one end of the connecting wire is connected to the external interface of the corresponding input-output combination, the other end of the connecting wire is connected to the corresponding first welding hole of the adapter board, and the corresponding second welding hole of the adapter board is connected to one end of the adapter socket;

[0053] The other end of the adapter socket of the first adapter module is connected to one end of the cable of the aircraft to be detected; the other end of the adapter socket of the second adapter module is connected to the other end of the cable of the aircraft to be detected.

Specifically, the external interface of each input-output combination in the first interface combination is connected to the cable of the aircraft to be detected through a first adapter module, and the external interface of each input-output combination in the second interface combination is connected to the cable of the aircraft to be detected through a second adapter module.

[0055] Specifically, the first adapter module and the second adapter module both include a standard cable, an adapter board and an adapter socket.

[0058] Specifically, different aircraft cables to be tested include different numbers of cables, and different adapters are provided.

By using the adapter of the same model to connect to the aircraft cable to be tested, the accuracy of the test is improved.

[0064] The wireless communication module, the MCU, the first interface combination, and the second interface combination are integrated on a PCB board;

[0065] The wireless communication module is connected to the communication port of the MCU.

[0066] Specifically, the wireless communication module is used for wireless communication with external devices, such as mobile phones, computers and other external device terminals. The wireless communication module starts to detect the aircraft cable to be detected according to the instructions of the external device terminal. After the detection is completed, the detection result can be transmitted back to the external device terminal through the wireless communication module, so that the user can view the detection result more conveniently.

[0070] Preferably, the MCU also includes an alarm indicator light.

[0071] Specifically, when testing the cable of the aircraft to be tested, if a cable break is detected, the user can be notified through an alarm indicator light. Specifically, the alarm indicator light is connected to the MCU, and when the MCU receives the result of the cable break, the alarm indicator light is controlled to notify the user, so that the user can understand the test situation more timely.
