[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] The present invention aims to solve the problem that the existing technology has a single detection function and no data interaction during helicopter repair and daily maintenance, making it impossible to perform original aircraft in-situ equipment detection and multi-system joint testing. By building a closed-loop measurement and control system, the excitation and output of each key system are uniformly planned, so that the excitation and response of each device system to be tested can be shared, realizing linkage testing between systems, and by building a standard aircraft model and applying responses according to technical requirements, the purpose of closed-loop testing and rapid troubleshooting is achieved.

[0041] Example 1

[0042] See also Figure 1 The present invention provides a helicopter intelligent detection system for detecting various physical components and equipment systems on a helicopter. Its subsystems include an original machine in-situ detection system, an ATE joint debugging platform, a semi-physical simulation platform and a standard machine system; the specific functions of each subsystem are set as follows:

[0043] Original aircraft in-situ detection system: used to detect various physical components and equipment systems without disassembling the helicopter and with each physical component in its original installation position; mainly includes specific functions such as data collection, fault diagnosis, performance parameter measurement, status monitoring and supervision.

[0044] It should be pointed out that the original in-situ detection system is the basis of the helicopter intelligent detection system. The system realizes the switching of test channels and functions of the system under test through the measurement and control system and the digital acquisition hardware, so that one set of equipment can complete the detection of multiple systems under test. The digital acquisition hardware uses non-destructive and flexible technology to perform equipment testing, fault location and damage assessment. The specific setting method can be selected according to actual conditions.

[0045] ATE joint debugging platform: Based on the original machine in-situ detection system, by injecting simulated excitation or fault signals into the system under test, and collecting feedback information from the system under test, the changes in feedback signals during normal excitation and fault excitation are displayed in a graphical manner. By comparison, it is tested whether the system under test is operating normally and the system's anti-interference and fault tolerance performance are verified.

[0046] Semi-physical simulation platform: Based on the original aircraft in-situ detection system, the real helicopter components (such as various sensors, ECUs, control mechanisms, etc.) are connected to the simulation loop for testing. During the ground maintenance and testing of the flight control system and accessory systems, it provides an actual environment that reflects the working status of the helicopter, and can effectively test the stability and flight characteristics of each helicopter system.

[0047] Standard machine system: The standard machine system consists of a standard machine database and an equivalent model. With the help of a semi-physical simulation platform and an ATE joint debugging platform, the same operation is performed on the repair machine and the simulated standard machine (the same stimulus signal is input, such as Figure 2 The response signals are compared to achieve rapid troubleshooting and performance evaluation.

[0048] Exemplarily, the original machine in-situ detection system can be set up by a measurement and control system, a performance parameter measurement system and a status monitoring system; wherein,

[0049] Measurement and control system: mainly completes the acquisition of analog and digital quantities such as temperature, pressure, flow, and speed, and the output of standard signals; controls the enabling of acquisition channels and the direction of data flow through switch switching, and realizes channel multiplexing and function switching when testing different systems;

[0050] Performance parameter measurement system: When multiple equipment systems to be tested are connected to the measurement and control system, channels are switched through switches, and the performance parameter measurement system switches accordingly, changing the conversion parameters and calculation algorithms, so as to measure the corresponding performance parameters;

[0051] Status monitoring system: During system operation, the status monitoring system determines the status based on the preset monitoring strategy and performs emergency processing when necessary.

[0052] Exemplarily, the ATE joint debugging platform can be set up by means of a simulation excitation system, an excitation injection system, a signal monitoring system and a whole machine joint debugging system;

[0053] The whole machine joint debugging system coordinates the simulation excitation system, excitation injection system, and signal monitoring system to perform different tasks according to the test requirements of the ground joint test, and integrates the task results through the comprehensive control of the whole machine joint debugging to verify the communication and functional status between the systems of each device under test;

[0054] First, the whole machine joint debugging system will simulate according to the joint testing requirements and generate corresponding normal excitation signals or fault excitation signals through the simulation excitation system;

[0055] Then, the excitation injection system cooperates with the measurement and control system to inject the normal excitation signal or the fault excitation signal into the corresponding device under test system through the data injection operation;

[0056] Finally, the feedback signal of the device under test is monitored through the signal monitoring system; the feedback signal is analyzed and processed to obtain the verification result, which is for the linkage between different systems and is different from the single system test.

[0057] Exemplarily, a semi-physical simulation platform can be set up through a physical model system, an actual equipment system, a mixed injection system, a signal monitoring system and an algorithm testing system; wherein the semi-physical simulation platform is mainly composed of an ECU closed-loop test, an operating system test and a control panel test system. By creating a physical model and cooperating with necessary actual equipment, simulated / real signals are input into the system under test, and the function of the system under test is checked by adjusting the input signal. Through a preset algorithm, the feedback signal of the system under test is analyzed to determine whether the system under test is working normally and stably.

[0058] In addition, since the helicopter detection system can provide comprehensive detection information from the individual to the whole, and does not leave the original position of the original aircraft, its data reliability is high; therefore, based on the helicopter detection, we also expand the comprehensive functions of this system by setting up a health management system to improve the reliability, maintainability and effectiveness of the equipment.

[0059] Health management refers to monitoring the system's operating parameters in various ways when the system is in operation or working state, and judging whether the system can work normally (mission capability) under the current conditions. In order to avoid the failure of certain operating processes causing the entire equipment system to be paralyzed, it is necessary to deal with the failure quickly after it occurs, maintain the normal basic functions, improve the utilization efficiency and safety of the equipment, and ensure safe and reliable operation.

[0060] The premise of health management is to understand the failure mechanism of the equipment. For example, abnormal vibration and noise signals of fluid rotating machinery provide important information for health management in the time domain and frequency domain, which is only part of the fault information; the load of fluid machinery and the changes in medium temperature, pressure and flow have an important impact on the operating status of the equipment and are often important factors leading to equipment abnormality and unstable operation.

[0061] Therefore, based on the information such as steady-state data, transient data, process parameters and operating status of the machine obtained by the helicopter detection system, we can determine the cause of the fault through fault symptom calculation, fault sensitive parameter extraction and comprehensive analysis and judgment, draw a practical diagnostic conclusion, and propose treatment measures.

[0062] During the operation of the system, the data platform collects, records and saves the data generated by each system. By building a data platform, the data is managed in a unified manner, thus providing data support for big data analysis and model training.

[0063] The setting of the instrument simulation system can display the performance parameters graphically in the form of instrument simulation, which is convenient for personnel to observe, understand, monitor and share.

[0064] Example 2

[0065] See also Figure 3 ,This embodiment provides a detection device, including a device mainboard, data acquisition hardware and an operation panel;

[0066] The system provided in Example 1 is mounted on the device mainboard of the detection device,

[0067] The data acquisition hardware can be connected to the physical components and equipment systems on the helicopter through aviation plugs (with adapter modules when necessary) (the connection relationship of the data acquisition hardware is as follows Figure 4 shown);

[0068] During use, the user selects the system to be tested through the operation panel. After selecting the system to be tested and the content to be tested, the system will run automatically, and the signals of interest and system status will be displayed in real time during the operation. After the operation is completed, the corresponding test report will be generated and the user will be prompted to end the test.

[0069] The above embodiments only express preferred implementation modes, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
