[0002] The proximity switch electronic component is part of the air-to-ground system and is an important component of the Boeing 737NG aircraft.

[0077] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0078] Example 1

[0079] As attached Figure 1 and appendix Figure 2As shown, this embodiment discloses a testing device for proximity switch electronic components, used to test whether the function of the proximity switch electronic component (not shown) is qualified. It mainly includes a device body 1, a simulation state control mechanism 3, a discrete signal control mechanism 2, a result state feedback mechanism 5, and an auxiliary signal transmission mechanism 10. In use, firstly, the power supply voltage is connected to the power interface 11 of the testing device; then, a signal transmission line (not shown) is used to connect the testing device to the electronic component; next, the simulation state control mechanism 3 is manipulated to simulate the state of an aircraft in the air or on the ground according to the current test requirements; then, the discrete signal control mechanism 2 is manipulated to control the transmission state of the discrete signals in the testing device according to the current state of the aircraft; during this process, the qualification status of the electronic component can be displayed on the result state feedback mechanism 5, thereby achieving the purpose of testing the electronic component.

[0080] The specific structure of the testing device is as follows: it includes a device body 1, which has a power interface 11 and a power button 13; an analog state control mechanism 3; a discrete signal control mechanism 2; a result state feedback mechanism 5; and an auxiliary signal transmission mechanism 10. Compared with the prior art, this invention has a simpler structure, lower cost, and higher practicality.

[0081] In a specific application scenario, the power interface 11 is an aviation interface; the aviation interface has the advantages of high reliability, durability, high protection level and easy installation and maintenance.

[0082] In a specific application scenario, a power button 13 is located on the lower side of the device body 1, and a power indicator light 14 is located to the right of the power button 13. After the testing device is connected to a power source, the operator presses the power button 13, and the power indicator light 14 will light up. At this time, the testing device can be used to test electronic components. The power button 13 is a rocker-shaped button, which is convenient for operators to press and can improve the user experience to a certain extent.

[0083] In a specific application scenario, as shown in the appendix Figure 1As shown, the result status feedback mechanism 5 includes a release fault indicator component 51, a non-release fault indicator component 52, and a landing signal indicator 53. The release fault indicator component 51 is located on the upper left of the device body 1, and the non-release fault indicator component 52 is located to the right of the release fault indicator component 51. The release fault indicator component 51 includes a first release fault indicator 511 and a second release fault indicator 512, and the non-release fault indicator component 52 includes a first non-release fault indicator 521 and a second non-release fault indicator 522, which correspond to whether the electronic component can collect or respond to the two states of the proximity sensor, namely, the state in the air and the state on the ground. The landing signal indicator 53 is located to the right of the first non-release fault indicator 521. When the electronic component erroneously detects the aircraft's landing signal, the landing signal indicator 53 will light up, indicating that the detection system of the electronic component has a problem, the function of the electronic component is unqualified, and the personnel need to take appropriate action.

[0084] Furthermore, as shown in the appendix Figure 1 As shown, the lower part of the result status feedback mechanism 5 is equipped with a discrete signal feedback mechanism 6; specifically, the discrete signal feedback mechanism 6 consists of several discrete signal status indicator lights. When the discrete signal in the test device is successfully transmitted to the electronic component, the corresponding discrete signal status indicator light will light up; when the discrete signal in the test device is not transmitted to the electronic component under test, the corresponding discrete signal status indicator light will not light up. This design makes it convenient for staff to check the transmission status of the discrete signal in the test device.

[0085] In a specific application scenario, the discrete signal control mechanism 2 mainly includes a falling edge signal triggered button 21 and several discrete signal control switches (not marked in the figure). See attached... Figure 1 As shown, the falling edge signal trigger button 21 is located on the front of the device body 1 and is situated to the right of the result status feedback mechanism 5. The falling edge signal trigger button 21 is electrically connected to the landing signal indicator light 53 in the aforementioned result status feedback mechanism 5. When the test device simulates an aircraft in the air, the operator presses the falling edge signal trigger button 21, and the test device can simulate the aircraft's descent signal. That is, pressing the falling edge signal trigger button 21 once is equivalent to simulating the aircraft descending a certain distance. At this time, the landing signal indicator light 53 will flash once, indicating that the simulated aircraft descent operation has been successful. During this process, the operator can obtain relatively accurate test information of the tested electronic components.

[0086] It should be noted that: after the simulated aircraft descends a certain distance, the test parameters of the electronic components should also be adjusted accordingly to obtain relatively accurate test results for the electronic components. The discrete signal control switch in the discrete signal control mechanism 2 is arranged on the right side of the result state feedback mechanism 5. The discrete signal control switch is electrically connected to the discrete signal feedback mechanism 6, and the discrete signal control switch is generally electrically connected to a discrete signal generator (not shown in the figure) in the device body 1.

[0087] In another specific application scenario, the discrete signal generator can be a discrete signal sensor; in addition, the number of discrete signal sensors does not strictly correspond to the number of discrete signal control switches. Some discrete signal sensors require multiple discrete signal control switches to be controlled simultaneously to meet the triggering conditions of the discrete signal sensor. That is to say, multiple discrete signal control switches need to be turned up simultaneously to trigger the corresponding discrete signal sensor; of course, the number of discrete signal control switches, the number of discrete signal sensors, and the electrical connection method between the discrete signal control switches and the discrete signal sensors can be appropriately adjusted by the user, and the corresponding content will not be elaborated here.

[0088] It should be noted that: as shown in the attached Figure 6 - attached Figure 12 figure, whether the discrete signal control switch S1 is turned up or down, the state of S1 is grounded, and the current discrete signal to be transmitted will be introduced into the currently tested electronic component from other pins on the auxiliary signal transmission mechanism 10.

[0089] In a specific application scenario, the analog state control mechanism 3 is mainly composed of several analog state control switches (not marked in the figure). The analog state control switches are electrically connected to an analog generator (not shown in the figure) in the device body 1. The signals simulated by the analog state control mechanism 3 are two states of the proximity sensor in the actual aircraft equipment, that is, the states in the air and on the ground. Turning up the analog state control switch simulates that the proximity sensor is in the air, that is, the state of the aircraft in the air; turning down the analog state control switch simulates that the proximity sensor is on the ground, that is, the state of the aircraft on the ground. Among them, there are a certain number of reserved switches in the analog state control mechanism 3, which are mainly reserved for the model upgrade of the tested electronic components in the future, resulting in an increase in the discrete quantities required by them. If the staff can identify and transmit the corresponding state information when detecting a certain electronic component, it means that the function of the electronic component is qualified; if the electronic component cannot identify and transmit the corresponding state information, it means that the function of the electronic component is unqualified. In addition, by manipulating different analog state control switches, different position information of the aircraft can be simulated, and such a design can obtain relatively accurate test information for the electronic components.

[0090] In a specific application scenario, the simulated state control switch can be a double-pole double-throw toggle switch. This design makes it convenient for staff to simulate switching the status information of an aircraft in the air or on the ground.

[0091] In a specific application scenario, the discrete signal control switch can be a single-pole double-throw toggle switch. This design facilitates the switching of discrete signal transmission or disconnection by the operator. Furthermore, both the analog state control switch and the discrete signal control switch shown in this embodiment are manually controlled and are equipped with a discrete signal feedback mechanism 6. This design makes maintenance, testing, and parameter adjustment more convenient and efficient for the operator. The electronic components used in this embodiment are all common electronic components, which allows for easy replacement, low manufacturing cost, and low maintenance cost.

[0092] In a specific application scenario, handles 15 are arranged symmetrically on both sides of the front of the device body 1. This design makes it convenient for staff to move the test device. The test device is not limited by the test site. Therefore, the testing of electronic components is not limited to a dedicated ATE workshop.

[0093] Example 2

[0094] As attached Figure 2 As shown, this embodiment discloses a testing device for proximity switch electronic components, used to enhance the working performance of the aforementioned embodiment 1. In addition to the components of the aforementioned embodiment 1, it also includes a circuit protection component 12. When an abnormal current occurs between the testing device and the electronic component, the electrical connection between the testing device and the electronic component under test will be automatically disconnected, thereby protecting the circuits in the testing device and the electronic component.

[0095] In a specific application scenario, a circuit protection component 12 is provided on the back of the device body 1.

[0096] In another specific application scenario, the circuit protection component 12 can be a fuse holder; whereby, when the fuse holder detects an abnormal current caused by a short circuit, it will melt its own fuse to cut off the corresponding circuit.

[0097] Example 3

[0098] As attached Figure 1 Appendix Figure 3 and appendix Figure 4As shown, this embodiment discloses a testing device for proximity switch electronic components to enhance the performance of the aforementioned embodiment 2. In addition to the components of embodiment 2, it also includes an auxiliary discrete signal transmission mechanism 7. Operators can connect the testing device 16, electronic component 17, and terminal 18 together using two discrete signal transmission lines (not shown in the figure). Discrete data fed back by the electronic component 17 can be transmitted to the terminal 18 via the auxiliary discrete signal transmission mechanism 7 and the testing device 16. The terminal 18 can save this discrete data, thereby generating a test report for the tested electronic component 17. This design facilitates the viewing and review of test reports by operators. Furthermore, the steps for generating a test report using the terminal 18 can be generally referred to the appendix. Figure 4 The content of that article will not be repeated here.

[0099] In a specific application scenario, the auxiliary discrete signal transmission mechanism 7 mainly includes a first discrete signal transmission interface 71 and a second discrete signal transmission interface 72. The first discrete signal transmission interface 71 is located on the lower side of the front of the device body 1, and the second discrete signal transmission interface 72 is located to the left of the first discrete signal transmission interface 71. Both the first discrete signal transmission interface 71 and the second discrete signal transmission interface 72 use RS232 signal transmission interfaces. When the operator needs to transmit discrete data from the electronic component 17 to the terminal 18, in addition to connecting the necessary signal lines and interfaces, it is also necessary to turn on the corresponding discrete signal control switch, as shown in the attached diagram. Figure 8 and attached Figure 9 RS232_1 and RS232_2 are used to control discrete signals. When RS232_1 and RS232_2 are flipped upwards, the corresponding discrete data can be transmitted normally. The discrete data received by terminal 18 includes fault codes and status information from the proximity sensor detected by the tested electronic component 17. Terminal 18 can be a laptop computer.

[0100] Example 4

[0101] As attached Figure 1 As shown, this embodiment discloses a testing device for proximity switch electronic components, which is used to enhance the working performance of the aforementioned embodiment 3. In addition to the components in the aforementioned embodiment 3, it also includes a data display mechanism 4. During the test, the data changes of the electronic component 17 will appear on the data display mechanism 4. This design makes it convenient for staff to view the relevant information.

[0102] In a specific application scenario, the data display device 4 includes a voltage meter 41 and a current meter 42. The voltage meter 41 is located on the upper side of the aforementioned allowable fault indicator component 51, and the current meter 42 is located to the right of the voltage meter 41. In use, if the aforementioned allowable fault indicator or non-allowable fault indicator lights up, the operator can identify the cause of the fault in the tested electronic component 17 based on the data displayed by the voltage meter 41 and the current meter 42, thereby improving the speed at which the relevant personnel handle the corresponding fault causes.

[0103] Example 5

[0104] As attached Figure 1 As shown, this embodiment discloses a testing device for proximity switch electronic components to enhance the working performance of the aforementioned embodiment 4. In addition to the components of the aforementioned embodiment 4, it also includes a first auxiliary testing mechanism 8. The operator can use an analog signal transmission line (not shown in the figure) to connect an oscilloscope to the testing device 16. The analog signal fed back by the electronic component under test 17 can be transmitted to the oscilloscope through the testing device 16. This design makes it convenient for the operator to view the waveform changes of the electronic component under test 17 when it is working, and then combine the data measured in the aforementioned embodiment 4 to determine whether the electronic component under test 17 is working normally, thereby obtaining more accurate test results.

[0105] In a specific application scenario, the first auxiliary detection mechanism 8 is located to the left of the aforementioned auxiliary discrete signal transmission mechanism 7. The eighth interface of the first auxiliary detection mechanism 8 is a reserved port; seven interfaces are actually usable, TP1-TP7, as shown in the attached diagram. Figure 6 -Appendix Figure 12 As shown, when the model of the analog signal connection cable between the oscilloscope and the testing device 16 changes, the operator can adjust the corresponding circuit to adapt to the current change. Furthermore, the voltage meter 41 and current meter 42 in the aforementioned embodiment 4 are generally pointer type, which may lead to incorrect readings by the operator, resulting in misjudgment of fault information. In this embodiment, however, the operator can make a comprehensive judgment based on the data they read and the information detected by the oscilloscope, thereby reducing the possibility of misjudgment.

[0106] Example 6

[0107] As attached Figure 1 -Appendix Figure 5As shown, this embodiment discloses a testing device for proximity switch electronic components to enhance the working performance of the aforementioned embodiment 5. In addition to the components in the aforementioned embodiment 5, it also includes a second auxiliary testing mechanism 9. The operator can use the connection cable of the multimeter 20 to connect the multimeter 20 to the testing device 16. This design makes it convenient for the operator to view the precise voltage or current values ​​of the electronic component 17 under test, and then combine the data measured by the oscilloscope 19 in the aforementioned embodiment 5 to determine whether the electronic component 17 under test is working properly, thereby obtaining more accurate test results.

[0108] In a specific application scenario, the second auxiliary detection mechanism 9 is located below the aforementioned power indicator light 14; wherein, the second auxiliary detection mechanism 9 includes an auxiliary detection positive interface 91 and an auxiliary detection negative interface 92, with the auxiliary detection positive interface 91 located above the auxiliary detection negative interface 92. In use, firstly, insert one end of the red and black probes into the corresponding positions on the multimeter 20 as required; then, insert the other end of the red probe into the auxiliary detection positive interface 91 and the other end of the black probe into the auxiliary detection negative interface 92. At this time, the multimeter 20 can detect the voltage or current value of the electronic component 17 currently being tested. The second auxiliary detection mechanism 9 is the power test jack 28V+ 28V- in the testing device 16, as shown in the attached diagram. Figure 6 -Appendix Figure 12 As shown. In this embodiment, the staff can make a comprehensive comparative analysis between the specific values ​​detected by the multimeter 20 and the waveform changes detected by the oscilloscope 19. This design allows the staff to locate the cause of the fault more quickly and accurately, and to carry out corresponding repairs.

[0109] The following description, using an optional embodiment, illustrates the content involved in the above embodiments.

During testing, prepare an analog signal transmission cable, generally DL_PSEU_963_J1-DL_PSEU_963_J7. One end of the cable is connected to the J1-J7 main connectors of the test device 16, and the other end is connected to the corresponding test interface of the electronic component 17.

[0112] The following is a partial description of the actual test process: When testing whether the electronic component 17 can receive signals from the aircraft on the ground, first, the analog state control switches S0194, S0199, S0301, S0302, S0071, S0073, S0195, S0200, S0845, S0846, S1010, S1012, S1014, S0853, S0854, S1011, S1013, and S1015 are flipped upwards, while the remaining analog state control switches are flipped downwards to simulate the state of the aircraft on the ground. Then, the discrete signal control switch S1 is flipped upwards to transmit the GEAR DOWN signal to the electronic component 17 under test. At this time, pin 6 of J1 in the auxiliary signal transmission mechanism 10 can be read as GND through the RS232 signal interface, indicating that the GEAR signal in the test device 16 is GND. The DOWN signal was successfully transmitted to the electronic component under test 17.
