All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
Fig. 1 is a diagram illustrating an abnormal signal alarm method according to an embodiment of the present invention, applied to a signal comparison system.
As shown in fig. 1, the method may include:
In the embodiment of the present invention, the image characteristic data and the sound characteristic data of the main path signal may be extracted, and the main path signal may be monitored for abnormal states, where the abnormal state monitoring is used to monitor abnormal states appearing in the final-stage signal, the abnormal states include a video abnormal state phenomenon and an audio abnormal state phenomenon, the video abnormal state phenomenon includes a static frame phenomenon, a black field phenomenon, a color bar phenomenon, and the like, and the audio abnormal state phenomenon includes a mute phenomenon of audio, an overhigh (low) volume of a left (right) channel, and the like. It is understood that the program signal anomaly may also include the case where the video anomaly phenomenon and the audio anomaly phenomenon exist simultaneously, for example: the mute frame phenomenon and the mute phenomenon exist at the same time, the black field phenomenon and the phenomenon of overhigh volume of the left sound channel exist at the same time, and the embodiment of the invention does not limit the phenomenon.
Further, consistency comparison can be performed on the main path signal and the standby path signal, specifically, data can be obtained by analyzing the signals, and synchronization and comparison of the signals are performed based on the data, so as to obtain whether the main path video signal and the standby path video signal are consistent, that is, a target comparison result. The target comparison result may be a comparison result of signal consistent representation of the main path signal and the standby path signal, or a comparison result of signal inconsistent representation of the main path signal and the standby path signal. And according to the information such as the detection parameter, the parameter threshold value and the like of the signal content, which one of the main path and the standby path is abnormal is judged. For example, feature parameters are extracted frame by frame for main path signals and standby path signals, and the two path signals are compared based on the feature parameters and statistical vectors, and common video statistical vectors include: mean, histogram, difference, gradient; common sound statistics vectors are: mean, zero-crossing rate, mean energy, cepstral coefficient, FFT coefficient, etc. The content of the alignment may include: whether the playing contents of the main and standby video and audio signals are consistent, whether local areas such as subtitles and station captions of the main and standby video and audio signals are consistent, and the like are not limited in the embodiment of the invention.
102, selecting an abnormal state alarm threshold corresponding to the target comparison result from preset abnormal state alarm thresholds according to the target comparison result, and using the abnormal state alarm threshold as a target abnormal state alarm threshold; the preset abnormal state alarm threshold comprises different abnormal state alarm thresholds corresponding to different comparison results.
In the embodiment of the invention, the abnormal state alarm threshold is the maximum frame number or time which can be broadcasted when the signal is in the abnormal state, can be set automatically according to the requirement, and is specifically used for alarming based on the abnormal state alarm threshold when the main path signal is monitored to be in the abnormal state.
The preset abnormal state alarm threshold values comprise different abnormal state alarm threshold values corresponding to different comparison results, namely the abnormal state alarm threshold values corresponding to the comparison results of the signal consistency representation and the abnormal state alarm threshold values corresponding to the comparison results of the signal inconsistency representation. Under the condition that the target comparison result is the comparison result of the consistent representation of the signals of the main path signal and the standby path signal, taking the abnormal state alarm threshold corresponding to the comparison result of the consistent representation as a target abnormal state alarm threshold to perform abnormal state monitoring based on the target abnormal state alarm threshold; and under the condition that the target comparison result is the comparison result of the inconsistent characterization of the signals of the main path signal and the standby path signal, taking the abnormal state alarm threshold corresponding to the comparison result of the inconsistent characterization as the target abnormal state alarm threshold, and carrying out abnormal state monitoring based on the target abnormal state alarm threshold.
And 103, outputting abnormal alarm information according to the abnormal information monitored by the abnormal monitoring operation and the target abnormal alarm threshold value.
In the embodiment of the present invention, the abnormal state information may include the number of frames of the main path signal in which the abnormal state occurs, and it can be understood that, in the television playing, a picture of 25 frames can be played in one second, and the abnormal state information may also be the time for which the abnormal state occurs in the main path signal.
And under the condition that the abnormal state of the main circuit signal is monitored, positioning the position where the abnormal state occurs, acquiring the abnormal state information of the main circuit signal, and outputting abnormal state alarm information based on the target abnormal state alarm threshold value. Wherein, abnormal alarm information can send to display screen, intelligent terminal, be used for controlling the controller of warning piece work. The intelligent terminal includes, but is not limited to, a smart phone, a notebook computer, and a desktop computer. The warning device includes but is not limited to a buzzer and a warning light.
In summary, in the embodiment of the present invention, the target comparison result is obtained by performing anomaly monitoring operation on the main path signal and performing consistency comparison on the main path signal and the standby path signal; according to the target comparison result, selecting an abnormal state alarm threshold corresponding to the target comparison result from preset abnormal state alarm thresholds as a target abnormal state alarm threshold; the preset abnormal state alarm threshold comprises different abnormal state alarm thresholds corresponding to different comparison results; and outputting abnormal alarm information according to the abnormal information monitored by the abnormal monitoring operation and the target abnormal alarm threshold value. Therefore, the flexibility of the alarm threshold used in abnormal state monitoring alarm is improved by presetting the preset abnormal state alarm threshold comprising different abnormal state alarm thresholds corresponding to different comparison results and dynamically selecting the required abnormal state alarm threshold from the different abnormal state alarm thresholds according to the current target comparison result, and the flexibility of abnormal state alarm can be further improved.
In addition, in the prior art, if the used alarm threshold value is to be changed, the alarm threshold value needs to be manually adjusted, and the monitoring function of the signal comparison system needs to be suspended during manual adjustment, so that the real-time state of the signal during manual adjustment cannot be monitored, and the broadcasting potential safety hazard is brought. In the embodiment of the invention, the single threshold does not need to be manually adjusted and changed, the required abnormal state alarm threshold is dynamically selected according to the target comparison result by presetting the preset abnormal state alarm threshold comprising different abnormal state alarm thresholds corresponding to different comparison results, and the used alarm thresholds are different under the condition that different target comparison results appear in the comparison process, namely, the used alarm threshold is changed, so that the broadcasting potential safety hazard caused by manually adjusting the abnormal state alarm threshold can be avoided to a certain extent.
Optionally, the comparison results include a first comparison result indicating that the signals are consistent and a second comparison result indicating that the signals are inconsistent. Specifically, under the condition that the signals of the main path signal and the standby path signal are consistent, a first comparison result is obtained, and the first comparison result corresponds to a first abnormal alarm threshold value; (ii) a And under the condition that the signals of the main path signal and the standby path signal are inconsistent, obtaining a second comparison result, wherein the second comparison result corresponds to a second abnormal alarm threshold value. Wherein the first anomaly alarm threshold is greater than the second anomaly alarm threshold. For example, the first abnormal alarm threshold is 50 frames (2 s), and the second abnormal alarm threshold is 25 frames (1 s), which indicates that the abnormal alarm threshold is larger under the condition that the signals of the main path signal and the standby path signal are inconsistent, and the abnormal alarm information is output more quickly when an abnormal state occurs.
In the embodiment of the invention, under the condition that the main path signal is inconsistent with the standby path signal, compared with the condition that the main path signal is consistent with the standby path signal, the main path signal has higher possibility of abnormal state occurrence, so that the abnormal state can be alarmed under different conditions by correlating the consistency comparison result of the main path signal and the standby path signal with the abnormal state alarm threshold, and when the main path signal and the standby path signal are inconsistent, the alarm threshold is shortened, so that the abnormal state can be timely treated correspondingly when occurring, the abnormal state alarm speed is accelerated, and the abnormal state processing speed is improved to a certain extent.
Optionally, the embodiment of the present invention further includes the following steps:
step 201, when the abnormal state monitoring operation is started on the main path signal, determining the first abnormal state alarm threshold as the target abnormal state alarm threshold.
In the embodiment of the invention, the first abnormal alarm threshold value can be used as an initial abnormal alarm threshold value, and abnormal monitoring operation can be carried out on the main path signal based on the first abnormal alarm threshold value.
Accordingly, the step 102 may include the steps of:
step 202, reading the second abnormal alarm threshold value in the preset abnormal alarm threshold values when the target comparison result indicates that the main path signal is inconsistent with the standby path signal.
In the embodiment of the invention, when the comparison result is the first comparison result, it is indicated that the current main path signal is inconsistent with the standby path signal, and the target abnormal state alarm threshold value is the second abnormal state alarm threshold value. And under the condition that the current target abnormal state alarm threshold is the first alarm threshold, reading a second abnormal state alarm threshold in the preset abnormal state alarm thresholds.
Step 203, switching the target abnormal alarm threshold value from the first abnormal alarm threshold value to the second abnormal alarm threshold value.
In the embodiment of the invention, after the second abnormal state alarm threshold corresponding to the first comparison result is read from the preset abnormal state alarm threshold, the target abnormal state alarm threshold is switched from the current first abnormal state alarm threshold to the second abnormal state alarm threshold, so that the abnormal state alarm threshold is shortened, and the alarm speed when the abnormal state occurs is accelerated.
In the embodiment of the invention, the first abnormal alarm threshold is determined as the target abnormal alarm threshold in advance, and the target abnormal alarm threshold is switched to the second abnormal alarm threshold corresponding to the inconsistency of the signals of the main and standby paths under the condition that the signals of the main and standby paths are inconsistent, because the first abnormal alarm threshold is larger than the second abnormal alarm threshold, the larger first abnormal alarm threshold is kept for abnormal monitoring under the condition that the signals of the main and standby paths are consistent, the frequency of abnormal alarm can be reduced, the accuracy of abnormal alarm is ensured, and when the signals of the main and standby paths are inconsistent, namely the probability of abnormal is higher, the target abnormal alarm threshold is shortened to the second abnormal alarm threshold, the alarm speed is increased, so that the abnormal processing speed can be increased, and the processing efficiency is improved.
Meanwhile, the abnormal state alarm threshold value does not need to be manually adjusted and changed, the corresponding abnormal state alarm threshold value is automatically switched according to different comparison results, the labor cost is saved, the broadcasting safety hidden danger caused by manual adjustment of the abnormal state alarm threshold value is avoided, the influence of manual operation on the broadcasting safety is avoided to a certain extent, and the program broadcasting effect is ensured while the overall safety of program broadcasting is improved.
Optionally, the preset abnormal state alarm threshold includes a second abnormal state alarm threshold corresponding to a second comparison result of different abnormal state types.
In the embodiment of the invention, the preset abnormal state alarm threshold comprises a second abnormal state alarm threshold corresponding to a second comparison result of different abnormal state types and a first abnormal state alarm threshold corresponding to a first comparison result of different abnormal state types.
Because the abnormal state comprises a video abnormal state phenomenon and an audio abnormal state phenomenon, in the existing requirements, the maximum allowable broadcasting time of different abnormal state types during broadcasting is different, if the broadcasting time of the abnormal state exceeds the maximum allowable broadcasting time, the broadcasting accident is judged, and therefore the abnormal state alarm threshold values corresponding to different abnormal state types are also different. For example, if the maximum allowed play-out time of the black field phenomenon is 50 frames (2 s), and the maximum allowed play-out time of the static frame phenomenon is 75 frames (3 s), the alarm threshold corresponding to the black field type in the first abnormal alarm threshold may be set to be less than or equal to the threshold of the maximum allowed play-out time, such as 50 frames (2 s), and the alarm threshold corresponding to the static frame phenomenon may be set to be less than or equal to the threshold of the maximum allowed play-out time, such as 75 frames (3 s); and setting the alarm threshold corresponding to the black field type in the second abnormal alarm threshold to be a threshold smaller than the first abnormal alarm threshold, such as 25 frames (1 s), and setting the alarm threshold corresponding to the static frame phenomenon to be a threshold smaller than the first abnormal alarm threshold, such as 50 frames (2 s). That is, the different-state alarm threshold value corresponding to the same different-state type when the main and standby signals are inconsistent is smaller than the different-state alarm threshold value corresponding to the different-state type when the main and standby signals are consistent.
Accordingly, step 202 may include the steps of:
step 301, determining the type of the abnormal state occurring in the main path signal as the target abnormal state type when the abnormal state monitoring operation monitors that the main path signal has the abnormal state and the target comparison result indicates that the main path signal is inconsistent with the standby path signal.
In the embodiment of the invention, when the situation that the main circuit signal is abnormal and the main circuit signal and the standby circuit signal are inconsistent is monitored, the target abnormal state alarm threshold value needs to be adjusted, and based on the situation, the abnormal state type of the current main circuit signal is determined as the target abnormal state type. Namely, if the black field phenomenon occurs in the current main path signal, the black field phenomenon is the target abnormal state type.
Step 302, reading a second abnormal state alarm threshold corresponding to a second comparison result of the target abnormal state type from the preset abnormal state alarm thresholds.
In the embodiment of the invention, after the target abnormal state type of the abnormal state of the current main path signal is determined, the second abnormal state alarm threshold value of the target abnormal state type corresponding to the second comparison result is read from the preset abnormal state alarm threshold value. For example: and reading a second abnormal state alarm threshold corresponding to the black field phenomenon when the main and standby signals are inconsistent under the condition that the black field phenomenon occurs in the current main path signal.
In the embodiment of the invention, by setting the second abnormal state alarm threshold values of different abnormal state types, the abnormal state alarm prompt can be carried out according to the actual abnormal state processing requirement when the main path signal has different abnormal state types, so that the accuracy of abnormal state monitoring is improved, and the overall safety of the broadcasting system is improved to a certain extent.
Optionally, the main path signal and the standby path signal are program signals of a currently broadcast program.
In the embodiment of the present invention, a program signal of a currently broadcast program of a current channel is divided into a main path signal and a standby path signal, where the main path signal may be an output signal, the standby path signal is a standby broadcast line correspondingly accessed by the broadcast switcher, and the standby path signal may be one path or multiple paths, which is not limited in this embodiment of the present invention.
The step 103 may further include the steps of:
step 401, outputting the abnormal alarm information when the abnormal information is greater than or equal to the target abnormal alarm threshold value.
In the embodiment of the invention, under the condition that the main path signal is abnormal, the number of the abnormal frames of the main path signal is more than or equal to the target abnormal alarm threshold value, the abnormal state is confirmed to need to be subjected to alarm operation, and abnormal alarm information is output.
Correspondingly, the embodiment of the invention also comprises the following steps:
step 402, under the condition of outputting the abnormal alarm information, switching the main path signal used by the current broadcast program into the standby path signal.
In the embodiment of the invention, under the condition of outputting abnormal alarm information, namely representing the abnormity of the main path signal, the main path signal used by the current broadcast program can be automatically switched into the standby path signal, wherein when the standby path signal is in a multi-path state, one path of standby path signal is selected for switching according to the switching strategy corresponding to the current broadcast program. It can be understood that, after the abnormal alarm information is output, the worker receives the alarm information and manually processes the abnormal condition of the main road signal.
Optionally, the preset abnormal alarm threshold is preset in an assigned configuration file.
In the embodiment of the present invention, a first abnormal alarm threshold and a second abnormal alarm threshold may be preset in a designated configuration file, where the first abnormal alarm threshold and the second abnormal alarm threshold may correspond to different logic codes, an alarm threshold defined in a logic code corresponding to the first abnormal alarm threshold is the first abnormal alarm threshold, and an alarm threshold defined in a logic code corresponding to the second abnormal alarm threshold is the second abnormal alarm threshold, and in a case where the first abnormal alarm threshold needs to be switched to the second abnormal alarm threshold, the logic code of the second abnormal alarm threshold may be read first and used as the logic code corresponding to the current abnormal alarm threshold. Correspondingly, when the logic code corresponding to the current abnormal state alarm threshold value is operated, the abnormal state alarm information can be automatically triggered and output when the abnormal state information is larger than or equal to the second abnormal state alarm threshold value, and the main path signal used by the current broadcast program is converted into the standby path signal. Specifically, when switching is performed, the switching instruction can be directly sent to the switching control panel through the SNMP network protocol, the SNMP control protocol is converted into the GPI serial port protocol by the switching control panel, and switching is automatically performed at the video switching line through the switching device.
In the embodiment of the invention, the preset abnormal state alarm threshold value is preset in the designated configuration file, so that when the target abnormal state alarm threshold value needs to be switched, the corresponding abnormal state alarm threshold value can be directly read from the designated configuration file, the monitoring function is not required to be suspended, the alarm threshold value is manually changed, and the signal comparison system is not required to be restarted, so that the processing efficiency is improved, and the comprehensiveness and the safety of signal monitoring are improved.
Optionally, the image characteristic data and the sound characteristic data of the standby channel signal may be extracted at the same time, and the abnormal state monitoring may be performed on the main channel signal and the standby channel signal at the same time, so as to perform the abnormal state monitoring on the standby channel signal. Meanwhile, when the backup path signal is abnormal, abnormal alarm information may be output by the abnormal alarm method in step 103, which is not described herein.
