[0018] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application. Identical or similar labels in the drawings represent identical or similar elements or elements with identical or similar functions. The described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0019] The present application provides an aero-engine finished accessory history management method, applied to a controller ground check instrument, as shown in the figure, the method comprises: Figure 1

[0020] Step S1, communicate with the engine controller, and obtain the first history information of each finished accessory recorded in the engine controller in advance;

[0021] Step S2, communicate with the finished accessory history management device, and obtain the second history information related to the finished accessory in the finished accessory storage card read by the finished accessory history management device;

[0022] Step S3, compare the first history information and the second history information, when the name and specified configuration parameters of the same type of finished accessory are consistent, write the finished accessory life information given by the engine controller into the corresponding finished accessory storage card, otherwise prohibit the engine ground start until the second history information in the finished accessory storage card is modified by the user to be consistent with the first history information.

[0023] In order to store accessory history information, the present application first provides an electronic storage card for each accessory, i.e. a finished accessory storage card. In the process of finished accessory leaving factory or field use, the electronic storage card is used to record the change of related history information. At the same time, the engine is equipped with a "finished accessory history management device", which can access all electronic storage cards of the engine which need to record the history information of finished accessories to read or modify each finished accessory storage card, and the process is controlled by the engine ground check instrument.

[0024] ​Since the ground inspection instrument is always connected during factory test run, and the ground inspection instrument needs to be connected after replacing important finished accessory in the field, the method is suitable for being integrated in the controller ground inspection instrument in the form of software, and only needs to connect the finished accessory history management device by the controller ground inspection instrument during ground run, so as to prompt the user to update the finished accessory history information through the interface of the ground inspection instrument (if not updated, the ground start is prohibited, the finished accessory information is displayed in the interface, and the user can select to update), thereby ensuring the accuracy of the recorded information and reducing the workload of the user in inputting related parameters.

[0025] The history information of the finished accessory is written into the engine controller during factory shipment or replacement, so that the controller ground inspection instrument can obtain the first history information from the engine controller in step S1, and the controller ground inspection instrument can obtain the second history information from each accessory storage card through the finished accessory history management device in step S2. In theory, the two history information should be the same. The controller ground inspection instrument compares whether the name of the finished accessory recorded in the engine controller and the name of the same type of finished accessory recorded in the finished accessory history management device are consistent, and whether the key configuration parameters are consistent, and if there is inconsistency, the interface prompts the user (including the function of selecting related information for the user), and the engine ground start is prohibited; if the comparison is consistent, the finished accessory life information in the engine controller is written into the corresponding accessory storage card.

[0026] In some optional embodiments, the first history information or the second history information includes the finished accessory type, name, life, calibration line and other key configuration parameters.

[0027] In some optional embodiments, in step S3, the finished accessory storage card is modified, and the modification includes:

[0028] Step S31, the finished accessory history management device sends the finished accessory history information in the specified storage card number to the controller ground inspection instrument according to the query instruction;

[0029] Step S32, the finished accessory history management device modifies the finished accessory history information in the specified storage card number according to the modification instruction.

[0030] The embodiment provides control logic of the finished accessory history management device, which can receive a query instruction (instruction format: CX+storage card number) communicated by the controller ground check instrument, and communicate finished accessory history information (including name, model, life information, key configuration parameters, etc.) recorded in the corresponding number storage card to the controller ground check instrument; or receive a modification instruction (instruction format: XG+storage card number) communicated by the controller ground check instrument, and modify the finished accessory history information recorded in the corresponding number storage card.

[0031] In some optional embodiments, for modification of the specified configuration parameter in the finished accessory history information, the original specified configuration parameter and the ID number of the finished accessory history management device are stored in the log area in the finished accessory storage card, and then the specified configuration parameter in the finished accessory history information is modified.

[0032] In the embodiment, if the modified history information is the key configuration parameter, the original key configuration parameter and the ID number of the corresponding finished accessory history management device are stored in the "important events" database of the storage card, and then the key configuration parameter is modified and the new finished accessory history management device ID number is recorded. The finished accessory history management device ID number is used to record the modification unit, so as to identify different users.

[0033] In some optional embodiments, the step S3 further comprises:

[0034] In step S4, during a test run, after the engine controller is powered on to receiving a start signal, all recorded finished accessory history information and engine monitoring parameters are continuously transmitted to the flight control system until the flight control system receives complete finished accessory history information. After the engine controller receives the start signal, only the engine monitoring parameters are transmitted. In the embodiment, in order to save the communication bandwidth between the aircraft and the engine, the finished accessory information in the same test run is fixed and unchanged.

[0035] In some optional embodiments, in step S4, the finished accessory history information is recorded into the flight data by the flight control system. The process is recorded only once, so that the engine finished accessory history information of the current test run can be directly extracted from the flight data.

[0036] The above merely provides specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed by the present application can be easily thought by those skilled in the art, and should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
