As shown in fig. 1, according to an embodiment of the present invention, there is provided a control software key instruction output method in combination with hardware condition judgment, including: setting hardware input conditions of control software according to key instructions of the control software; setting a software input condition of control software; the control software judges whether the hardware input condition is valid or not through the bottom switch measuring board, if the hardware input condition is invalid, the control software returns to judge whether the hardware input condition is valid or not through the bottom switch measuring board until the hardware input condition is valid; if the hardware input condition is valid, judging whether the software input condition of the control software is valid, and if the software input condition of the control software is valid, outputting a key instruction by the control software; and if the software input conditions of the control software are invalid, returning to judge whether the software input conditions of the control software are met or not until the software input conditions of the control software are met.
By applying the configuration mode, the control software key instruction output method combined with hardware condition judgment is provided, and the control software key instruction output method combined with hardware condition judgment judges whether the software input condition is effective or not on the basis that the hardware input condition of the control software is effective by setting the hardware input condition and the software input condition of the control software, and controls the software to output the key instruction under the condition that the software input condition is effective. The method adds a layer of hardware-based input conditions in the software input conditions, so that the output of the key instruction is not only dependent on the judgment of the software data conditions, but also overlapped with the hardware, and the reliability and the safety of the execution of the key instruction are improved. Compared with the prior art, the technical scheme of the invention can solve the technical problem of insufficient reliability of key instruction output of control software.
In order to realize the output of key instructions of control software, the invention firstly sets the hardware input condition of the control software according to the key instructions of the control software.
After determining that a certain key instruction is a key instruction of control software, setting a hardware input signal which is related to the key instruction and can be received by the control software before the key instruction is output as a locking condition. As a specific embodiment of the invention, the hardware locking condition can be set to be double-path redundancy backup, each path of input signals has an independent excitation source, and control software can read two paths of redundant input signals through a bottom layer interface. By setting the hardware locking condition of the double-path redundancy backup, the reading success rate of the hardware input condition of the control software can be improved, and the phenomenon that the key instruction output of the control software is invalid due to the fact that the hardware input condition cannot be read is avoided.
Further, in the present invention, after setting the hardware input condition of the control software, the software input condition of the control software is set. As a specific embodiment of the invention, the key data threshold value for sending the key instruction of the control software can be set as the software input condition, and the key data value and the key data threshold value are obtained by comparing the calculation of the control software to judge whether the software input condition of the control software is valid or not, so as to determine whether to execute the output of the key instruction of the control software.
In addition, after setting the software input condition of the control software, the control software judges whether the hardware input condition is valid or not through the bottom switch measuring plate, and if the hardware input condition is valid, the control software judges whether the software input condition of the control software is valid or not; if the hardware input condition is invalid, the control software returns again to judge whether the hardware input condition is valid or not through the bottom switch measuring plate until the hardware input condition is valid.
In the invention, the hardware input condition is invalid, namely, when the hardware locking condition is not released, the software instruction is not responded, and the software input condition is not required to be judged; only when the hardware input condition is valid, i.e., the hardware lock condition is released, will the software instruction be responded to. Once the hardware lock condition is released, the hardware lock condition is not judged any more and only the software instruction is responded. The invention can improve the judging efficiency of the key instruction output condition of the control software, save the flow and improve the reliability and safety of the key instruction output.
As a specific embodiment of the invention, any one of the two-way input signals in the hardware locking condition is valid, the hardware input condition is considered valid, so that the reliability of controlling the key instruction output of the software can be improved.
Further, in the invention, whether the software input condition of the control software is valid is judged, and if the software input condition of the control software is valid, the control software outputs a key instruction; and if the software input conditions of the control software are invalid, returning to judge whether the software input conditions of the control software are met or not until the software input conditions of the control software are met. In the invention, only after the hardware input condition is met, the control software calculates whether the software input condition is met or not, otherwise, calculation is not needed. And once the control software confirms that the hardware input conditions are met, the control software calculates the software input conditions without limitation, and the aircraft output instruction can be output as long as the hardware input conditions are met.
The invention provides a control software key instruction output method combining hardware condition judgment, which abandons the traditional output method of obtaining key instruction time sequence only depending on software internal data calculation result, and adds a layer of hardware-based input condition in the software condition, so that the entry condition of a branch is overlapped with hardware instead of only depending on the judgment of the software data condition, thereby improving the execution reliability of the key instruction. The method ensures that the key instruction is sent out effectively, and improves the reliability and safety of the key instruction output. The method is helpful for improving the effectiveness of judging the key instruction condition, does not depend on a single instruction, and can improve the reliability of the functions of the aircraft. The method has been generalized to a number of project applications and achieves very good results.
According to another aspect of the invention there is provided a computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, the processor implementing any of the methods described above when executing the computer program.
For further understanding of the present invention, the following describes the key instruction output method of the control software according to the present invention in conjunction with hardware condition determination with reference to fig. 1.
As shown in fig. 1, according to an embodiment of the present invention, a method for outputting a critical instruction of control software in combination with hardware condition determination is provided, where an aircraft output instruction 1 is taken as a critical instruction, and the aircraft output instruction 1 is a switching value output signal, and is controlled by aircraft control software.
Step one, setting the aircraft input signal 1 and the aircraft input signal 2 as hardware input conditions of aircraft control software according to the aircraft output instruction 1, namely, hardware locking conditions of the output instruction 1. The aircraft input signal 1 and the aircraft input signal 2 are switching value signals, the two paths are mutually independent, and control software can identify whether the aircraft input signal 1 and the aircraft input signal 2 are valid or not through a bottom layer switching value board.
Step two, setting the software input conditions of the control software: and setting the speed of the aircraft to be larger than a first threshold value and the flight angle to be smaller than a second threshold value as a software input condition of control software.
Step three, the control software takes 5ms as a sampling period, judges whether the aircraft input signal 1 or the aircraft input signal 2 lasts for 500ms through a bottom switch measuring plate of the aircraft control machine, if so, the hardware input condition is valid, and further judges whether the software input condition of the control software is valid; if not, the hardware input condition is invalid, and the control software is returned again to judge whether the hardware input condition is valid or not through the bottom switch measuring plate until the hardware input condition is valid.
Judging whether the software input condition of the control software is valid or not: the control software takes 5ms as a sampling period, calculates whether the software input condition lasts for 200ms, if yes, meets the set software input condition, and can send out an aircraft output instruction 1 at the moment; if not, the set software input conditions are not met, and the method returns to judge whether the software input conditions of the control software are met or not until the software input conditions of the control software are met.
In summary, the present invention provides a control software key instruction output method combined with hardware condition judgment, where the control software key instruction output method combined with hardware condition judgment is to set a hardware input condition and a software input condition of control software, judge whether the software input condition is valid based on the validity of the hardware input condition of the control software, and control the software output key instruction under the condition that the software input condition is valid. The method adds a layer of hardware-based input conditions in the software input conditions, so that the output of the key instruction is not only dependent on the judgment of the software data conditions, but also overlapped with the hardware, and the reliability and the safety of the execution of the key instruction are improved. Compared with the prior art, the technical scheme of the invention can solve the technical problem of insufficient reliability of key instruction output of control software.
