Description

TECHNICAL FIELD

[0001] The present application relates to the field of electric rudder system information management, and particularly relates to an electric rudder system information storage and query method. BACKGROUND

[0002] The electric rudder system is a classic actuator in the field of aerospace, and is an important part of the flight control system of integrated systems such as rockets, missiles or unmanned aerial vehicles. After the electric rudder system is delivered to the customer after completing the test with the integrated system, the state of the electric rudder system needs to be checked and confirmed during the regular inspection of the integrated system, and the basic file information (model, product name, product code, production number, software fingerprint code, date of manufacture and manufacturer, etc.) of the electric rudder system and the important history information (cumulative power-on time, cumulative power-on times, overvoltage value and its duration, overcurrent value and its time, motor overheating value and its time, and rudder system fault type code, etc.) are confirmed to confirm the state of the rudder system.

[0003] During the regular inspection and confirmation process, the basic file information of the electric rudder system such as the model, code, number and date of manufacture is quickly confirmed; before the flight task, the important history information such as the cumulative power-on time and the cumulative power-on times is queried to ensure that the state of the electric rudder system itself can continue to carry out the flight task; during the maintenance and repair process, the important history information such as the overvoltage value and its duration, the overcurrent value and its time, the rudder and the rudder controller overheating value and its time, and the rudder system fault type code are queried to quickly confirm the state and locate the fault problem. Improve the supportability and maintainability of the electric rudder system.

[0004] The traditional electric rudder system does not have the functions of querying and feeding back the basic file information and important history information. When performing maintenance confirmation, the model, code, number, fingerprint code and date of manufacture of the electric rudder system are confirmed through the matching “paper data” or “other medium data”. When the number of electric rudder systems to be checked and confirmed is large, the data to be reviewed is also increasing, which increases the cost, reduces the maintenance efficiency and is prone to errors; when confirming the remaining service life of the electric rudder system, only the flight test time and the ground test time are recorded and confirmed, and it is easy to be missed. During the rudder system repair and problem finding process, only the “fault phenomenon description” of the “on-site operator” is used for speculation, and the available information for fault positioning is less. SUMMARY

[0005] The present application aims to overcome the technical problems in the prior art and provides an electric rudder system information storage and query method. The basic file information and important history information of the electric rudder system are recorded, stored and queried to improve the convenience and speed of rudder system maintenance and repair.

[0006] The object of the present application is achieved by the following technical solutions: The application discloses an electric rudder system information storage and query method. After initialization of the electric rudder system is completed, basic profile information in the storage chip and important history information in a previous working process are loaded; During storage, working state information of the electric rudder system is collected and stored in real time, and the working state information is stored in a specific address area corresponding to the important history information, wherein a storage operation is performed once every certain time interval; During query, the electric rudder system receives an informationized query instruction sent by a flight control combination, reads the stored basic profile information and important history information, and feeds back the information to the flight control combination.

[0007] In some embodiments, the working state information includes a cumulative power-on number, a cumulative power-on time, voltage, current, temperature and a rudder system failure mode.

[0009] In some embodiments, when the cumulative power-on time is stored, the cumulative power-on time is added once every 1 second on the basis of the cumulative power-on time in the previous working process until the rudder system is powered off.

[0010] In some embodiments, when the voltage, current and temperature are stored, corresponding threshold trigger recording conditions are set.

[0011] In some embodiments, when the rudder system failure mode is stored, a failure code corresponding to the failure is written into a specific address area of the storage chip.

[0012] In some embodiments, the electric rudder system feeds back the read basic profile information and important history information to the flight control combination according to an agreed instruction frame format.

[0013] In some embodiments, the electric rudder system is connected with the flight control combination in communication through an on-board cable (or an on-aircraft cable).

[0014] It should be further explained that the technical features corresponding to the above-mentioned embodiments can be combined or replaced with each other to form new technical solutions without conflict.

[0015] Compared with the prior art, the present application has the following beneficial effects: 1.The application records and stores the "basic profile information" and "important history information" of the electric rudder system in a specific area of the storage chip.

[0018] The technical solutions of the application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the application, not all embodiments. The components of the embodiments of the application described and shown in the drawings can be arranged and designed in various different configurations. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.

[0019] It should be noted that the defects in the above prior art solutions are the result of the inventors' practice and careful study, therefore, the discovery process of the above problems and the solutions proposed by the embodiments of the application to solve the above problems should be the contribution of the inventors to the application during the process of invention and creation, and should not be understood as technical content known to those skilled in the art.

[0020] To solve the technical problems pointed out in the background art, the embodiments provided by the application are as follows: In an exemplary embodiment, an electric rudder system information storage and query method is provided, comprising: After the initialization of the electric rudder system is completed, the basic profile information in the storage chip and the important history information in the previous working process are loaded; When storing, the working state information of the electric rudder system is collected and stored in real time, and the working state information is stored in a specific address area corresponding to the important history information, wherein a storage operation is performed once every certain time interval; When queried, the electric rudder system receives the information query instruction sent by the flight control combination, reads the stored basic profile information and important history information, and feeds back to the flight control combination.

[0021] Specifically, after the electric rudder system is powered on and initialized, the basic profile information stored in the specific address area of the storage chip and the important history information recorded and stored in the previous working process are loaded out while the rudder position feedback signal is collected in real time and the rudder position control instruction sent by the flight control combination is received for closed-loop control. At the same time, the information such as voltage, current, temperature, etc. that needs to be collected and recorded in real time is collected and recorded, and a storage operation is performed every certain time T. Among them, for the important history information (such as cumulative power-on time and cumulative power-on times) that needs to be continuously recorded, it is loaded out and recorded and stored in real time on this basis. For the important history information (such as voltage, current, temperature and rudder system failure mode) that needs to be recorded only when the threshold is reached, the threshold is set, and when the trigger condition is reached, the corresponding voltage value, current value, temperature and its duration are stored in the specific address area of the storage chip. At the same time, the state of the electric rudder system is monitored in real time, and when the abnormal state of the rudder system is monitored, the fault code is stored in the fixed address of the storage chip.

[0022] Further, in the ground maintenance mode, when the basic profile information and important history information of the rudder system need to be queried, the flight control combination needs to send an information query instruction to the rudder system, and the rudder system enters the information query mode. After receiving the basic profile information query instruction, the basic profile information stored in the storage chip is read and fed back to the flight control combination according to the agreed instruction frame format. After receiving the important history information query instruction, the important history information stored in the storage chip is read and fed back to the flight control combination according to the agreed instruction frame format. The electric rudder system is connected with the flight control combination through the on-board cable. The flight control combination can query through RS422 communication, CAN bus communication and 1553B bus communication.

[0023] Figure 1 As shown, the present embodiment takes the cumulative power-on times, cumulative power-on time, voltage, current, temperature, and specific storage of rudder system failure mode as an example to illustrate the method. Specifically as follows: 1. Cumulative power-on times: After the rudder system is initialized, the "cumulative power-on times" power_on_count stored in the specific address area during the previous working process are loaded out, and after a "accumulation operation" is performed on this basis, the accumulated power_on_count is written to the specific address area of the storage chip.

[0024] 2. Accumulated power-on time: After the initialization of the rudder system is completed, the "accumulated power-on time" power_on_time stored in the specific address area during the previous working process is loaded out, and then the accumulated power_on_time is added every 1 second, and the accumulated power_on_time is written to the specific address area of the storage chip, which continues until the rudder system is powered off. Among them, the interval time can be adjusted according to the actual situation, which is not explained as a limitation of the present application.

[0025] 3. Overvoltage value and its duration: After the initialization of the rudder system is completed, the "maximum working voltage value" U stored in the specific address area during the previous working process is loaded out, and when the voltage is greater than U, the timing is started and the maximum working voltage (Umax) recorded during the working process is recorded. When the voltage is lower than U, the maximum working voltage recorded during the working process and the duration T1 are written to the specific address area of the storage chip.

[0026] 4. Overcurrent value and its time: After the initialization of the rudder system is completed, the "maximum working current value" I stored in the specific address area during the previous working process is loaded out, and when the current is greater than I, the timing is started and the maximum working current (Imax) recorded during the working process is recorded. When the current is lower than I, the maximum working current recorded during the working process and the duration T2 are written to the specific address area of the storage chip.

[0027] 5. Rudder controller and rudder overheating value and time: After the initialization of the rudder system is completed, the "maximum working temperature value" TPE stored in the specific address area of the rudder and the rudder controller during the previous working process is loaded out, and when the temperature is greater than TPE, the timing is started and the maximum working temperature (TPEmax) of the rudder and the rudder controller recorded during the working process is recorded. When the temperature is lower than TPE, the maximum working temperature recorded during the working process and the duration T3 are written to the specific address area of the storage chip.

[0028] 6. Rudder system fault type code: After the initialization of the rudder system is completed, the running state of the rudder system is monitored, and when the rudder system fails, the fault code corresponding to the fault (such as: the fault code corresponding to the communication exception is AA, the fault code corresponding to the following exception is BB, the fault code corresponding to the position sensor exception is CC, the fault code corresponding to the power supply exception is DD, and the fault code corresponding to the motor exception is EE, etc.) is written to the specific address area of the storage chip.

[0029] Further, the basic file information of the electric rudder system, such as the type, product name, product code, production number, software fingerprint code, factory date and manufacturer, is loaded, and the basic file information is fed back to the flight control combination when a basic file information query instruction is received. When an important history information query instruction is received, the cumulative power-on times, cumulative power-on time, voltage, current, temperature, rudder system failure mode and other information stored above are fed back to the flight control combination.

[0030] The above detailed description is a detailed description of the present application, which cannot be considered as limiting the specific embodiments of the present application only to these descriptions. For ordinary skilled persons in the technical field to which the present application belongs, a number of simple deductions and substitutions can be made without departing from the concept of the present application, and all of them should be considered as belonging to the protection scope of the present application.
