Detailed Description
The present invention will be further described with reference to the accompanying drawings, and the following description is only for clearly illustrating the technical solutions of the present invention, and the protection scope of the present invention is not limited thereby.
The invention provides a remote signaling detection method based on multi-level filtering, which comprises the following steps: s1, collecting the original remote signaling signal, and carrying out primary filtering processing; s2, time accumulation filter processing is performed on the signal processed in S1.
FIG. 1 is a flow chart of the present invention, which includes the following steps: s11, continuously acquiring remote signaling original signals at certain intervals, and storing the remote signaling original signals in sequence; s12, judging the S11 storage signal according to the mode of M-to-N, acquiring a secondary signal, and storing the secondary signal in sequence; s13, judging the S12 storage signal, continuously accumulating the same secondary signals for X times, and generating a tertiary signal; s21, obtaining a three-level signal to generate a preliminary displacement event, and beginning to accumulate anti-shake time; s22, after the preliminary displacement event, if a reverse secondary signal is obtained, the anti-shake time is cleared; and S23, after the initial displacement event, accumulating the anti-shake time to a threshold value, generating a real displacement event, and recording the telecommand displacement.
And when the system is started, the system is in the S1 stage, digital sampling is carried out on the remote signaling pins at regular time through the timer, and the remote signaling original signal values are obtained and stored in sequence. And (3) carrying out polarity judgment on the stored signal value in a 7-to-4 mode: if the sampling value of the latest 7 times is more than or equal to 4 times and is 0, the polarity of the current signal is judged to be 0; otherwise, if the number of times is more than or equal to 4, the polarity of the current signal is judged to be 1; the processed signal is the secondary signal. With the sampling of the original signal, when the accumulation of the continuous secondary signals with the same polarity reaches 8 times, a stable signal value is considered to be obtained, a tertiary signal is output, namely, a preliminary displacement event is generated, and the method enters an S2 time accumulation filtering stage; if the secondary signal fluctuates, the system stays at the stage and waits for a stable signal interval.
At the stage of S2, as the original signal sampling is carried out, the three-level signal is kept for reaching the anti-shake threshold time, namely a real displacement event is generated; if the secondary signal fluctuates to cause the interruption of the value of the tertiary signal, the anti-shake time is counted from 0 to prevent false triggering.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
