The execution subject can be adjusted according to the specific case, such as a server, an electronic device, a computer, and the like.

The embodiment of the invention provides a control method for a rocket engine torch ignition remote control instruction end, which is used for the torch ignition of a recoverable liquid carrier rocket variable thrust electric engine, is mainly responsible for issuing aperiodic control instructions and receiving and processing periodic time sequence data, and has good interpretability. By configuring the xml file to self-define the generating configuration items, the problem of repeated development of conventional engine flare ignition is avoided.

In one aspect of the embodiments of the present invention, referring to fig. 1, a method for controlling a remote control command end for rocket engine torch ignition is provided, including:

and responding to the starting instruction, and sending an initial detection instruction to the control end by the remote control instruction end. The remote control instruction end and the control end are similar to the relationship between an upper computer and a lower computer, the remote control instruction end is equivalent to the upper computer and is used for carrying out interactive operation with a user, the control end is equivalent to the lower computer and is used for receiving an instruction sent by the user through the remote control instruction end to execute response operation, and an execution result is fed back to the remote control instruction end. Optionally, the initial detection instruction includes: communication interface inspection instruction, equipment self-checking instruction, sensor self-checking instruction, valve test instruction.

And responding to a return command returned by the control end, and the remote control command end executes interface display to prompt whether to perform time sequence parameter binding.

And responding to the time sequence parameter binding instruction, and reading an xml configuration file by the remote control instruction terminal to perform item configuration to form a configuration item corresponding to the xml configuration file. By reading the xml configuration file, the xml configuration file can be configured to define the configuration items, and the test configuration items are realized by combining with the service requirements, so that the problems of frequent change and repeated development of the conventional engine torch ignition are solved. The contents and structure of the xml configuration file are described in detail in an embodiment below.

And the remote control instruction end sends a control instruction corresponding to the configuration item to the control end.

And the remote control instruction end receives and processes the periodic time sequence data returned by the control end. Optionally, the periodic time series data includes: torch state data, valve state data, sensor data. Preferably, the periodic timing data is real-time periodic 10ms timing data.

The remote control command end mainly executes two types of tasks, one type is aperiodic command control, and the other type is real-time periodic 10ms time sequence data receiving processing. In the aerospace activity, the measurement data and events acquired and recorded by each measurement and control station must have the same strict and uniform time standard to be analyzed and processed, so that the application value is realized. The time signal is also used for controlling a program instrument to complete the ignition of the rocket and the missile and enable the instrument to work according to the program. The standardized time system equipment has the functions of time difference measurement, delay correction, leap second, leap year, time setting, fault alarm and the like, has high reliability and stability, is distributed in each large measurement and control station, and provides a unified time frequency signal format for the measurement and control equipment. The aperiodic command mainly refers to some preparation work before the timing signal, such as checking equipment self-checking, sensor value self-checking, testing valve operation, and the like. The remote control instruction end real-time periodic 10ms time sequence data receiving and processing mainly comprises real-time periodic 10ms time sequence data such as torch state, valve state, sensor data and the like which are issued after the control end receives the timing signal.

It should be noted that, the steps of the embodiment of the present invention are not limited in the written order of priority, but are executed in response to a trigger condition. And when the trigger condition of a certain step is met, executing a corresponding process. The order in which the steps are performed is consistent with the inherent logic understood by those skilled in the art.

In an implementation manner of the embodiment of the present invention, referring to fig. 2, the receiving and processing of the periodic time series data returned by the control end by the remote control instruction end includes:

and responding to a drawing instruction, and analyzing the periodic time sequence data and drawing a pattern by the remote control instruction end. When the periodic real-time sequence data is analyzed, in order to prevent the data from being lost and difficult to interpret due to factors such as bus interference, Bit inversion and the like, when the issued real-time sequence data is analyzed, the number bytes of the control end are found according to an agreed protocol and are subjected to graph drawing, and the problem that the real-time drawing data is lost and difficult to check can be solved.

Further, the analyzing the periodic time series data and drawing a pattern by the remote control instruction end includes:

extracting the serial number and the time sequence value of the periodic time sequence data;

and drawing by using a QCustomplot component by using the number as an X axis and the time sequence value as a Y axis. The step can clearly display the corresponding relation between the serial number and the time sequence data, and solve the problem that real-time drawing data is lost and difficult to check. The QCustomPlut component is a Qt-based drawing and data visualization C + + control. The QCustomPlut component is used for programming, so that the portability and the reusability are good.

In one implementation of the embodiment of the present invention, referring to fig. 3 and 4, the xml configuration file adopts a multi-level tree structure. And the xml is stored in a tree form through the DOM, so that the operation is simple and the access is convenient. Specifically, the xml configuration file comprises a plurality of state modes, each state mode comprises a plurality of inspection classifications, and each inspection classification comprises a plurality of configuration item tests. The xml tree structure is configured in conjunction with business requirements.

In an implementation manner of the embodiment of the present invention, after the remote control instruction end sends the initial detection instruction to the control end:

and if the command returned by the control end is not received within the preset time, continuously sending an initial detection command to the control end.

The working process of the torch ignition remote control command end of the variable thrust electric engine is described as follows in combination with FIG. 2:

a) all hardware equipment is in place, power is on, software is started, and initialization is completed.

b) The torch ignition remote control instruction end of the variable thrust electric engine sends a non-periodic control instruction to the control end, receives an instruction return instruction within a specified timeout period, and performs interface display to prompt whether to perform time sequence parameter binding.

c) And after the time sequence parameters are bound, receiving periodic time sequence data.

d) And receiving periodic time sequence data of a control end, analyzing the number of the frame, and drawing and storing the frame.

According to the ignition remote control instruction end control method, the configuration items are generated by defining through configuring the xml, and the problems of frequent change and repeated development of the conventional engine torch ignition are solved. When real-time periodic 10ms time sequence data are processed, the serial number and the time sequence value in the time sequence data are extracted, the serial number of the time sequence data is used as an X axis, the time sequence value is used as a Y axis for drawing, whether the data are lost or not can be visually seen, and the problem that the conventional engine torch ignition real-time drawing data are lost and difficult to check is solved. And the remote control instruction end uses the QCustomPlut component for drawing, and has better portability.

In the process of issuing the periodic real-time data, in order to prevent data loss caused by factors such as bus interference, Bit overturn and the like from being difficult to interpret, when the time sequence data is issued, all the periodic time sequence data are numbered, and the problem that the conventional engine torch ignition real-time drawing data is lost and difficult to check can be solved. That is to say, the problem that real-time data are lost and difficult to check is solved by numbering time series data, and the interpretation efficiency is improved.

The problem that data are lost and difficult to investigate can be solved by numbering the sequential data, but correspondingly, if the numbers are arranged in sequence, the difficulty in cracking the data is easily reduced, the data are easily stolen, and if the numbers are arranged in non-sequence, the reduction effect on the difficulty in investigating the real-time data loss is limited. Therefore, in an optional embodiment, a third data group is generated according to the first data group which is not repeated and out of order and the second data group which is not repeated and in order, the time series data is numbered by using the data in the third data group, the ignition control device checks the time series data lost by the stream according to the third data group and the first data group, wherein optionally, each data in the third data group is the sum of the data in the corresponding second data group and the second data, when the ignition control device checks the time series data lost by the stream according to the third data group and the first data group, the third data group can be obtained according to the time series data which is numbered, the third data group subtracts the first data group to obtain the second data group, and the lost time series data is determined according to whether the data lost in the second data group or not. Illustratively, the first data group is [3, 5, 1], the second data group is [1, 2, 3], then, the third data group is [4, 7, 4], since the time series data is numbered by the third data group, the third data group is [4, 7, 4] can be obtained according to the number of the time series data, and then, according to the first data group [3, 5, 1], the second data group [1, 2, 3] can be obtained by calculation, and since the second data group is sequential data, the lost data in the second data group can be rapidly judged. When the time series data is illegally acquired, the third data group is out of order, so that the actual order of the time series data cannot be known under the condition that the first data group is unknown, and an illegal acquirer is difficult to decode and restore the time series data according to the number, so that the problem that the time series data is difficult to lose and check can be solved, and the safety of the time series data can be improved.
