[0036] Figure 1 It is a structural schematic diagram of an aircraft handheld tester provided in an embodiment of the present disclosure. DETAILED DESCRIPTION

[0037] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0038] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0039] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0040] Figure 1 This is a schematic diagram of the structure of the aircraft handheld tester provided by the embodiment of the present disclosure. Figure 1 , the aircraft handheld tester 100 comprises:

[0041] A rotary switch 101 , a controller 102 , a comparator 103 , an operator 104 , an adjustable resistor 105 and a detection unit 106 .

[0042] The rotary switch 101 is connected to a controller 102. The controller 102 is used to connect to an external engine 200.

[0043] The rotary switch 101 and the external engine 200 are both connected to the comparator 103 . The comparator 103 is connected to the operator 104 .

[0044] The controller 102 is connected to an adjustable resistor 105. The adjustable resistor 105 is used to connect to an external engine 200.

[0045] The detection unit 106 is used to be connected to the external engine 200. The detection unit 106 is connected to the calculation unit 104.

[0046] In this embodiment, the knob switch 101 is directly operated by the user and is used to send a start / stop signal to the controller 102. The controller 102 is the core control component of the aircraft handheld tester 100. The controller 102 can directly control the start / stop operation of the external engine 200 according to the state of the knob switch 101.

[0047] The comparator 103 is an electronic device for receiving the actual working status from the knob switch 101 and the external engine 200. The function of the comparator 103 is to compare whether the two signals received are consistent, and then send the judgment result to the operator 104. The operator 104 is the core computing component of the aircraft handheld tester 100. The operator 104 can determine whether the current external engine 200 is in a normal state or a fault state according to the judgment result of the comparator 103. In addition, the operator 104 can also involve processes such as logic judgment, signal amplification, algorithm processing or calculation, and instruction adjustment.

[0048] For example, when the rotary switch 101 is in the start state, a high level signal is sent to the comparator 103, and when the rotary switch 101 is in the off state, a low level signal is sent to the comparator 103; when the external engine 200 is in the start state, a high level signal is sent to the comparator 103, and when the external engine 200 is in the stop state, a low level signal is sent to the comparator 103. When the comparator 103 receives two consistent level signals (both signals are high level signals or both signals are low level signals), a high level signal is sent to the operator 104, and the operator 104 can judge that the current external engine 200 can be controlled by the rotary switch 101 to make a corresponding state response based on the electrical signal, that is, the external engine 200 is in a normal state. When the comparator 103 receives two inconsistent level signals (the two signals are a high level signal and a low level signal), a low level signal is sent to the operator 104. The operator 104 can determine based on the electrical signal that the current external engine 200 cannot make a corresponding status response according to the control of the knob switch 101, that is, the external engine 200 is in a fault state.

[0049] The adjustable rheostat 105 is a device that controls the throttle size of the external engine 200 by controlling the access current. The controller 102 can be connected to the adjustable rheostat 105 to control the adjustable rheostat 105 to change the access resistance. The adjustable rheostat 105 serves as an actuator of the controller 102 and is connected to the external engine 200 to change the current or voltage of the external engine 200, thereby dynamically controlling the power output (i.e., the throttle size) of the external engine 200 to achieve precise control.

[0050] For example, when the external engine 200 is started normally, the controller 102 can control the adjustable rheostat 105 to gradually change the size of the connected resistance within a specified time to ensure that the external engine 200 gradually increases the throttle. The controller 102 can also control the adjustable rheostat 105 according to a pre-set gear mode to ensure that the external engine 200 changes the throttle size under different gears.

[0051] The detection unit 106 may include a variety of detection instruments, and by connecting to the external engine 200, monitor various operating parameters of the external engine 200 in real time, such as temperature, rotation speed, voltage, current, vibration, etc. The detection unit 106 may feed back the detection data to the operator 104, and the operator 104 may analyze various performance parameters of the external engine 200 in real time, thereby ensuring that the external engine 200 can operate safely.

[0052] It can be concluded from the above that this embodiment can achieve comprehensive control and debugging of the external engine 200 through the interconnection and collaborative work between various components, save manual testing costs, improve testing efficiency, and ensure the performance and safety of the aircraft external engine 200.

[0053] In one embodiment of the present disclosure, the aircraft handheld tester 100 further includes:

[0054] Parameter adjustment unit.

[0055] The computing unit 104 is connected to a parameter adjustment unit. The parameter adjustment unit is used to connect to an external engine 200.

[0056] In this embodiment, since the operating parameters of each engine may be different in different operating states, in order to be able to comprehensively test the operating parameters of each external engine 200 in each operating state, a parameter adjustment unit may be provided to adjust the operating parameters of the external engine 200. The parameter adjustment unit may include a parameter adjustment button and a parameter adjustment chip. The parameter adjustment button is used to input the parameter value to be adjusted, and the parameter adjustment chip is used to receive and send the corresponding parameter adjustment instruction.

[0057] The operator 104 can be connected to the parameter adjustment unit. After processing the real-time detection data from the detection unit 106 and the feedback from the comparator 103, it can not only directly control the adjustable resistor 105 according to the calculation result, but also transmit the calculation result to the parameter adjustment unit. The parameter adjustment unit directly fine-tunes the specific parameters of the engine according to the instructions given by the operator 104, for example, it may involve the fuel mixture ratio, ignition timing, turbine speed, etc. By adjusting the operating parameters of the external engine 200, it is placed in different operating states so as to better test it.

[0058] It can be concluded from the above that the present embodiment can change the operating state of the external engine 200 through the parameter adjustment unit, and can also adapt to different models of external engines 200, meet the personalized testing needs of aircraft engines in different stages or conditions, so as to perform more accurate and comprehensive testing on them, and improve the overall intelligence level of the test.

[0059] In one embodiment of the present disclosure, the aircraft handheld tester 100 further includes:

[0060] Decoder.

[0061] The rotary switch 101 and the external engine 200 are both connected to the decoder, and the decoder is connected to the comparator 103 .

[0062] In this embodiment, the decoder is an electronic device that can translate the status signals of the knob switch 101 and the external engine 200. The knob switch 101 and the external engine 200 are both connected to the decoder. Each switch action of the knob and the status information of the external engine 200 will be captured by the decoder and converted into a digital signal or a level signal. This process improves the accuracy and safety of the operation instructions and avoids misoperation. The digital signal or level signal obtained by the decoder is then transmitted to the comparator 103, and the comparator 103 compares the two signals. The addition of the decoder ensures the accurate transmission of the instructions and the correctness of the execution.

[0063] It can be concluded from the above that this embodiment can improve the accuracy of instruction transmission, and the decoding process helps to avoid signal interference and errors in the signal transmission process. At the same time, it can also accurately transmit the signal to the next level judgment process, thereby improving the test accuracy of the entire tester.

[0064] In one embodiment of the present disclosure, the detection unit 106 includes:

[0065] Pressure detector, temperature detector, vibration detector, speed detector.

[0066] The input ends of the pressure detector, the temperature detector, the vibration detector and the rotation speed detector are all used to connect to the external engine 200 .

[0067] The output ends of the pressure detector, the temperature detector, the vibration detector and the rotation speed detector are all connected to the operator 104 .

[0068] In this embodiment, the detection unit 106 may include: a pressure detector, a temperature detector, a vibration detector, a speed detector, etc. Among them, the pressure detector can be used to detect the pressure parameters of the external engine 200 (for example, fuel pressure, cylinder pressure, etc.); the temperature detector can be used to detect the temperature parameters of the external engine 200 (for example, engine temperature, coolant temperature, exhaust temperature, etc.); the vibration detector can be used to detect the vibration frequency of the external engine 200; the speed detector can be used to detect the speed of the external engine 200 (for example, crankshaft speed, turbine speed, etc.).

[0069] The input ends of the above detectors can be directly connected to the external engine 200 to detect various operating parameters of the external engine 200 in real time. The output ends of the above detectors are connected to the operator 104 to transmit the detected data to the operator 104 in real time for further data processing by the operator 104. The operator 104 can summarize all the detection data, perform comparison, calculation, alarm threshold judgment and other processes, or feed back to the controller 102 to adjust the working state of the external engine 200 through the adjustable resistor 105 to perform the next test operation.

[0070] It can be concluded from the above that this embodiment can not only realize multi-dimensional, real-time and accurate detection of the engine operating status, provide a data basis for fault prevention and maintenance of the external engine 200, but also ensure the safety of the external engine 200 after it is put into use.

[0071] In one embodiment of the present disclosure, the aircraft handheld tester 100 further includes:

[0072] Display.

[0073] The adjustable resistor 105 and the operator 104 are both connected to the display screen.

[0074] In this embodiment, in order to facilitate real-time observation of the test results of the current external engine 200, a display screen can be set to display the control resistance value of the adjustable rheostat 105 and the data processing results of the operator 104. The adjustable rheostat 105, as an actuator of the controller 102, is responsible for adjusting the output power of the external engine 200 according to the instructions of the operator 104, and the working state of the adjustable rheostat 105 or the parameter changes adjusted by it can be fed back to the display screen in real time. This means that the operator can intuitively see the current setting of the adjustable rheostat 105 through the display screen, so as to accurately understand the current working state of the external engine 200.

[0075] The calculation result and data processing process of the operator 104 as the core processing unit can be directly displayed on the display screen, providing the operator with a real-time monitoring window of the operation status of the external engine 200, including engine parameters, execution status of adjustment instructions, fault diagnosis feedback, etc.

[0076] From the above, it can be concluded that this embodiment can provide the operator with an intuitive test interface by adding a display screen. The operator can quickly understand the current operating status of the aircraft engine without professional knowledge, which greatly improves the convenience and safety of the test operation and the timeliness of fault handling.

[0077] In one embodiment of the present disclosure, the aircraft handheld tester 100 further includes:

[0078] shell.

[0079] The knob switch 101, the controller 102, the comparator 103, the operator 104, the adjustable resistor 105 and the detection unit 106 are all arranged inside the housing. The display screen is arranged on the outer surface of the housing.

[0080] In this embodiment, in order to protect the various electronic components from damage by the external environment and extend their service life, a housing may be provided to provide physical protection for all internal components of the tester and prevent external environmental factors, such as dust, moisture, impact, etc., from damaging the delicate electronic components. The housing is usually made of durable materials, such as high-strength plastic or lightweight metal alloy (aluminum molded housing), which ensures both portability and durability of the entire tester.

[0081] Among them, the key components such as the knob switch 101, the controller 102, the comparator 103, the operator 104, the adjustable resistor 105 and the detection unit 106 can all be integrated inside the housing. This layout is conducive to neat wiring and maintenance of the circuit, and also reduces the impact of external interference on sensitive electronic components. The display screen can be set on the outer surface of the housing. This design makes it easy for the operator to directly read the test results and status information. The display screen can be made of LCD or LED material.

[0082] It can be concluded from the above that this embodiment can optimize the practicality and operational convenience of the entire aircraft handheld tester 100 and also enhance its adaptability in harsh environments.

[0083] In one embodiment of the present disclosure, the aircraft handheld tester 100 further includes:

[0084] Storage.

[0085] The computing unit 104 is connected to the memory.

[0086] In this embodiment, the storage is a memory component used to store data and instructions. After processing the real-time data, the operator 104 of the tester can not only use it for immediate control decisions, but also transmit these processed data, historical records, calculation results, control instruction sequences and other information to the storage. The storage is responsible for long-term preservation of these valuable data records, providing historical basis for subsequent fault tracing, performance evaluation, aircraft maintenance, and optimization strategy formulation. The addition of the storage enables the handheld tester to not only respond to control in real time, but also provide important data support for the long-term management, performance improvement, and fault prevention of the aircraft.

[0087] It can be concluded from the above that this embodiment can provide the operator with historical test data, so that the operator can review the performance status of various aspects of the aircraft external engine 200 according to the data records, and realize the intelligent and information management of the aircraft external engine 200 test data.
