The shapes and sizes of the various elements in the drawings are not to be considered true scale, but are merely illustrative of the implementations described in the exemplary embodiments below.

Example one

The embodiment one provides an aircraft engine maintenance training system 100. As shown in fig. 1, the aircraft engine maintenance training system 100 may include: an aircraft engine simulation model 110, a detection system 120, and a monitoring system 130. Wherein the detection system 120 may be connected to the monitoring system 130.

Alternatively, the aircraft engine simulation model 110 may be used to carry physical or simulated components of a real aircraft engine.

For example, the aircraft engine simulation model 110 may be a physical part or a simulation part of an aircraft engine of CFM56 series, taking an example of a real aircraft engine of CFM56 series. For example, the external dimensions of the aircraft engine simulation model 110 are the same as or highly similar to the external dimensions of the CFM56 series aircraft engines, and the materials, dimensions, and connection relationships of the components of the aircraft engine simulation model 110 are the same as or highly similar to the materials, dimensions, and connection relationships of the components of the aircraft engine simulation model 110.

For example, the apparent dimensions of the aircraft engine simulation model 110 may be set to: 4 meters (length) by 2.10 meters (width) by 2.30 meters (height); the total weight is 1000 kg; the input power supply is set as 220V alternating current power supply. The connection components of the aircraft engine simulation model 110 may be english fasteners. For example, all the connecting bolts and nuts on the body part of the aircraft engine simulation model 110 may be the same as the original english connecting bolts and nuts of the CFM56 series aircraft engine, and the same as the connecting mode of the CFM56 series aircraft engine, so that a trainee can master the practical training skills for disassembling and assembling and maintaining the aircraft engine in the teaching process.

Specifically, the aircraft engine simulation model 110 includes a plurality of controllable components 111. Wherein any one of the controllable elements 111 may comprise a plurality of attachment points thereon.

In particular implementations, the plurality of controllable components 111 may include, but are not limited to: the fuel/oil heat exchanger 9, the fuel filter cover 7, the left fuel nozzle 3, the right fuel nozzle 10, the fan blade 19, the rear rectifier cone 1, the N2 speed sensor 5, the tail cone 4, the HPTACC control valve 11, the air/oil heat exchanger 8, the high-pressure rotor input cover 6 and the fuel flow sensor 2.

Alternatively, the detection system 120 may include a plurality of sensors respectively disposed at a plurality of attachment points of any of the controllable elements 111, i.e., one attachment point may correspond to one or more sensors. The detection system 120 may detect and acquire operation information of a trainee performing each maintenance operation on any of the controllable elements 111 in real time through a plurality of sensors provided at a plurality of detachable points of any of the controllable elements 111. The maintenance operation may be an operation of removing or installing any of the points of removal of any of the controllable components 111.

In a specific implementation process, the detection system 120 can achieve real-time detection and information feedback in a practical teaching process through a plurality of sensors on a plurality of dismounting points of any controllable component 111, so that the maintenance operation of a student can be monitored in real time, the student can conveniently carry out dismounting training on corresponding components strictly according to the requirements of a maintenance manual, and the training effect can be greatly improved.

For example, the switch inside the sensor may be formed by a conductive contact pin and a conductive contact plate. When the outside uses tools such as spanner to operate the dismouting point that is equipped with this sensor, if external operating force or distance reach triggering condition, then can trigger the contact of the inside electrically conductive contact pilotage of sensor and electrically conductive touch panel, produce corresponding switch signal of telecommunication, at this moment, can explain that the dismouting point that is equipped with this sensor is dismantled or is installed. In particular, the sensor may be one of a normally closed sensor (e.g., a nut pull out sensor), a normally open sensor (e.g., a screw in sensor), and a proximity sensor. In a specific implementation process, the sensors of corresponding types can be arranged on the dismounting points according to the structural characteristics of the dismounting points, so that the accuracy of sensor detection can be improved. For example, a normally closed sensor may be provided at a point of attachment/detachment of the fuel/oil heat exchanger 9; a normally open sensor may be provided at the point of disassembly of the air/oil heat exchanger 8; a proximity sensor may be provided at the point of detachment of the fan blade 19. Alternatively, the sensor may be a pressure sensor, and when the external user operates the detachable point provided with the sensor using a tool such as a wrench, if the pressure value detected by the sensor satisfies a corresponding condition, it may be determined that the detachable point provided with the sensor is detached or attached.

Alternatively, the monitoring system 130 may be configured to determine whether each maintenance operation performed by the trainee on any one of the controllable components 111 is correct according to the operation information, and count and output the result of the maintenance training of the trainee. That is, the monitoring system 130 may output the maintenance training result while determining whether the maintenance operation of the trainee is correct according to the received sensor detection data.

For example, the input power of the monitoring system 130 may be set to 12V dc power.

In a specific implementation process, in a scene of multi-machine monitoring, the monitoring system 130 may allow N detection systems 120 (corresponding to N aircraft engine simulation models 110) to be networked, may support N trainees to disassemble and assemble the same component, and simultaneously monitors and records the disassembling and assembling processes, so as to realize a skill competition between the trainees, increase the interest of learning and training, and contribute to improving the enthusiasm of the trainees in actual operation and training, where N is an integer greater than or equal to 2 and less than or equal to 6. In the single-machine monitoring scenario, the monitoring system 130 is networked with the detection system 120, so that the dismounting operation of 2 students can be monitored simultaneously, and whether the dismounting operation is performed according to the correct dismounting order specified by the maintenance manual can be monitored.

Optionally, as shown in conjunction with fig. 1-5, the monitoring system 130 may include an information input module 131, a status monitoring module 132, a control module 133, and an information output module 134. The information input module 131, the status monitoring module 132, and the information output module 134 may be respectively connected to the control module 133.

Optionally, as shown in fig. 1-5, the information input module 131 may be used for one or more of input, modification, deletion, and selection of related information. Specifically, the related information may include, but is not limited to: student number information and password information, identification information and operation order information of any one of the controllable sections 111, and related functions. The related functions may include, but are not limited to: component disassembly, component assembly, state monitoring and result statistics. Wherein the identification information of any one of the controllable parts 111 may be number information.

For example, in order to standardize and count the effect of student operation training, the power of the monitoring system 130 may be turned on, and the operation of component disassembly, assembly and maintenance performed by the student may be monitored. In the process, the student can input his own scholar number information and password information through the information input module 131, and then select a corresponding function, for example, select component disassembly, and finally, the student can select the component to be disassembled and the operation sequence thereof through the identification information and the operation sequence information of the controllable component 111, so that the subsequent monitoring system 130 can monitor the component disassembly training performed by the student, and count and feed back the training result of the student.

Illustratively, an administrator of the monitoring system 130 can, but is not limited to, alter or delete the identification information and operational sequence information of any of the controllable components 111 via the information input module 131.

It should be noted that, if the aircraft engine simulation model 110 is used for teaching, for example, when unidirectional course teaching such as fuse and english tool usage is directly performed on the aircraft engine simulation model 110, the monitoring system 130 is not needed, and at this time, the power supply of the monitoring system 130 may be disconnected.

Alternatively, as shown in fig. 1 to 5, the control module 133 may be configured to control operations of the status monitoring module 132 and the information output module 134 according to the information acquired by the information input module 131.

Alternatively, as shown in fig. 1 to 5, the status monitoring module 132 may be configured to monitor the statuses of the plurality of controllable components 111 under the control of the control module 133 when the control module 133 determines that the information acquired by the information input module 131 is the information for selecting status monitoring.

For example, when the trainee/administrator selects to monitor the states of the plurality of controllable components 111 through the information input module 131, the control module 133 may control the state monitoring module 132 to monitor the states of the plurality of controllable components 111.

Specifically, the interface information may include, but is not limited to: information input page information, score output page information, function selection page information and fault point position display page information.

For example, when the trainee opens the monitoring platform provided by the monitoring system 130, the control module 133 may control the information output module 134 to display the information input page information, and at this time, the trainee may input his/her own number information and password information based on the information input page information through the information input module 131 to log in the monitoring platform. After the trainee successfully logs in the monitoring platform, the control module 133 may control the information output module 134 to display the function selection page information, and at this time, the trainee may select the status monitoring function based on the function selection page information through the information input module 131. When the control module 133 detects and confirms that the student selects the status monitoring function, the status monitoring module 132 may monitor the statuses of the plurality of controllable components 111, for example, the status of the controllable components 111 is monitored by the sensors on the controllable components 111, and at this time, if the control module 133 confirms that a fault point (the controllable component 111 or the detachable point) exists based on the detection data fed back by the sensors on the controllable components 111, the control information output module 134 may be controlled to display the fault point location display page information, so that the student can conveniently confirm the location of the fault point. Alternatively, when the trainee selects the score counting function based on the function selection page information through the information input module 131, the information output module 134 may be controlled to display the score output page information, so that the trainee can confirm his training score.

Alternatively, as shown in connection with fig. 1-5, the control module 133 may comprise an ARM industrial control chip.

Corresponding interface information can be displayed through the display screen, prompt voice can be output through the voice output device, a student can be convenient to concentrate on maintenance operation, and maintenance operation or maintenance operation stopping can be carried out according to the prompt voice.

In a specific implementation process, the display screen and the voice output device may be integrally arranged or may be independently arranged, which is not limited in this embodiment.

In a specific implementation process, when the information input module 131 and the information output module 134 are integrated together, the display screen may be a touch display screen, which may display corresponding interface information, and may support one or more of input, change, deletion, and selection of related information.

Alternatively, as shown in connection with FIGS. 1-5, the aircraft engine simulation model 110 may also include a fan case 20. The fan case 20 may be provided with an engine electrical circuit, and the engine electrical circuit may be connected to the control module 133, so as to provide a standard circuit construction practice training, thereby supporting a trainee to perform a standard circuit construction training based on a national skill competition.

Alternatively, as shown in connection with FIGS. 1-5, the aircraft engine simulation model 110 may also include a plurality of uncontrollable components for component disassembly training.

To facilitate understanding of the technical solution of the first embodiment, the following description will take an example of the disassembly and assembly training of the fuel flow sensor by using the aircraft engine maintenance training system 100.

For example, the assembly and disassembly training process for the fuel flow sensor using the aircraft engine maintenance training system 100 may include the following:

firstly, the power supply of the aircraft engine simulation model 110 is switched on, the monitoring system 130 is simultaneously switched on, a fuel flow sensor is prepared, and the following steps are carried out after the fuel flow sensor is prepared, wherein the number of the fuel flow sensor is 1:

disassembling:

the first step is as follows: the monitoring system 130 will voice prompt "part No. 1 is operating correctly" when the electrical plug is disconnected from the fuel flow sensor.

The second step is that: the left 4 anchor bolts are removed (no disassembly sequence required, every time a bolt is removed, the monitoring system 130 will voice prompt "part No. 1 operates correctly").

The third step: the right 4 anchor bolts are removed (no disassembly sequence required, every time a bolt is removed, the monitoring system 130 will voice prompt "part No. 1 operates correctly").

The fourth step: the monitoring system 130 outputs a voice prompt: "part No. 1 operation is complete, you congratulations".

The installation step:

the first step is as follows: install 4 fixing bolts on the left side oil pipe flange (no installation order requirement, every time install a bolt, monitoring system 130 would voice prompt "part No. 1 operates correctly").

The second step is that: install 4 fixing bolts on the right side oil pipe flange (no installation order requirement, every time install a bolt, monitoring system 130 will voice prompt "No. 1 part operates correctly").

The third step: when the electrical plug is installed, the monitoring system 130 prompts the user that the operation of the No. 1 component is correct through voice.

While the above steps are performed, the monitoring system 130 monitors whether the dismounting process is correct, and when the operation of each step is correct, the system completes the operation of each step, the monitoring system 130 prompts by voice: "part No. 1 operates correctly," until all operations are completed, the monitoring system 130 prompts with voice: "part No. 1 operation completed, congratulation of you"; when one of the steps is wrong, the monitoring system 130 prompts by voice: "part No. 1 operates erroneously, stops operating". The monitoring system 130 may output statistics of operation results of all the trainees after monitoring the operation process of each trainee, so that the teacher can know the actual operation level of each trainee and give reasonable evaluation.

It should be noted that the trainee must strictly follow the requirements of the service manual to perform the disassembly and assembly training, so as to obtain the voice prompt of "correct operation" of the monitoring system 130, and perform the next operation.

As can be seen from the above description, the aircraft engine maintenance training system 100 provided in this embodiment can support various training items such as use training, fuse training, standard circuit construction training, component disassembly and assembly training of various english-system tools, and can have the characteristics of controllable operation, sustainable use, easy-to-damage component replacement at any time, low teaching cost, high teaching efficiency, teaching practice investment saving, high training interestingness, and the like.
