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.

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 numbers and the time sequence data, and solves 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 terminal sends the initial detection instruction to the control terminal:
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, powered on, software is started, and initialization is completed.
b) The variable thrust electric engine torch ignition remote control instruction end 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 the real-time periodic 10ms time sequence data is 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 data are lost and difficult to check in the conventional engine torch ignition real-time drawing is solved. And the remote control instruction end uses a 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] according to the number of the time series data, and then the second data group [1,2,3] can be calculated according to the first data group [3,5,1], 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.
