Fig. 3 is a diagram showing the software architecture of the player 100 according to an embodiment of the present invention. The software architecture of the player 100 includes a monitoring module 310, a frame analysis module 320, a troubleshooting module 330, and an exception reporting module 340.

The operation of the above elements can be further described with reference to the following corresponding methods.
Fig. 4 shows a flowchart of a method for repairing a digital billboard according to an embodiment of the invention. The method for overhauling the digital billboard according to the embodiment of the invention can be applied to the digital billboard playing system 10 shown in fig. 1. For example, the method may be performed by the processor 110 of the player 100 shown in fig. 1.
First, in step S402, the monitoring module 310 is activated to load and detect the processor (e.g., CPU) usage status of one or more processing programs corresponding to a playback software through the monitoring processing program of the monitoring module. Specifically, each player software may have a processing program list including one or more corresponding processing programs used by the player software for playing, and these processing program lists may be pre-stored in the storage device 120, so that the monitoring module 310 can know which processing programs to perform subsequent monitoring according to the processing program list of the player software used for playing. In this embodiment, the monitoring handler detects the CPU utilization of all the handlers in the list once every first time period (e.g., 30 seconds).
Next, in step S404, the monitoring module 310 determines whether a predetermined condition is satisfied according to the CPU utilization status of the monitored processing program. In one embodiment, the monitoring module 310 determines whether the predetermined condition is satisfied and determines whether the CPU utilization rates of all the monitored processing programs are zero according to the CPU utilization states of the monitored processing programs, determines that the predetermined condition is satisfied when the CPU utilization rates of all the monitored processing programs are zero, and determines that the predetermined condition is not satisfied when the CPU utilization rate of any processing program is not zero. In another embodiment, the monitoring module 310 determines whether a predetermined condition is satisfied according to the CPU usage status of the monitored processing programs, determines whether the number of times that the CPU usage rates of all the monitoring processing programs are zero exceeds a predetermined number of times, determines that the predetermined condition is satisfied when the number of times that the CPU usage rates of all the monitoring processing programs are zero is greater than the predetermined number of times, and determines that the predetermined condition is not satisfied when the number of times that the CPU usage rates of all the monitoring processing programs are zero is not greater than the predetermined number of times.
Specifically, when the playing software of the player 100 is abnormal, the multimedia information, such as the advertisement content, played by the digital billboard 200 will stop playing and generate a black picture, and at this time, the CPU utilization rate occupied by each processing program used by the playing software will become zero. According to the detection mechanism of the embodiment of the invention, only when the predetermined condition is satisfied, the operation of reading the data of the current frame from the storage device 120 and performing frame sampling and comparison to detect the current screen frame is started, so that a large amount of unnecessary memory data access can be saved, the number of data access times and time can be greatly reduced, thereby effectively detecting whether the frame is abnormal or not, and improving the monitoring efficiency.
When the predetermined condition is satisfied, in step S406, the frame analysis module 320 is activated to detect whether a frame is abnormal. Specifically, whether the screen is abnormal or not is detected, and whether the current screen is a black screen or not is detected. Since each pixel point in the black image is a black pixel point, the image analysis module 320 can determine whether the image is abnormal by checking whether each pixel point of the current image is a black pixel point.
In some embodiments, the monitoring module 310 periodically monitors the CPU utilization status of the processing program for a first time period, and continuously determines whether the predetermined condition is continuously satisfied according to the CPU utilization status of the processing program for a second time period when the predetermined condition is determined to be satisfied, wherein the second time period is shorter than the first time period. For example, the monitoring module 310 may monitor the CPU utilization status of each related processing program at the frequency detected every 30 seconds and determine whether the CPU utilization rates of all the processing programs are all zero, if it is detected that the CPU utilization rate of any processing program is not zero, continue to monitor the CPU utilization status of the processing program at the frequency detected every 30 seconds, and detect the occurrence number of times that the CPU utilization rates of the processing programs are all zero at the frequency detected every 10 seconds when it is detected that the CPU utilization rates of all the processing programs are all zero, thereby greatly shortening the detection time of the monitoring module 310. In an embodiment, the monitoring module may further determine the number of times the predetermined condition is detected to be satisfied, and when the number of times the predetermined condition is continuously detected to be satisfied is greater than a predetermined number of times, the screen analyzing module 320 may detect whether the screen is abnormal, so as to avoid the occurrence of misjudgment. For example, the monitoring module 310 may start to detect whether the subsequent frames are abnormal or not only when it is continuously detected that the CPU utilization of all the processing procedures occurring three times or more in 30 seconds is zero.
In response to the detection of the abnormal picture by the picture analysis module 320, in step S408, the troubleshooting module 330 is activated to execute an automatic troubleshooting process. In one embodiment, the automatic troubleshooting process is performed by automatically restarting the playing software, but the invention is not limited thereto. When the playing software is restarted, the multimedia information can be played on the digital billboard again, so that the content which is originally stopped to be played can be quickly played continuously. In one embodiment, the anomaly reporting module 340 is activated to generate an anomaly record about the anomaly time point and transmit an image anomaly message to a remote device (not shown) via a network (not shown) in response to the image analysis module 320 detecting that the image is anomalous (i.e., black image). In this embodiment, the player 100 can be coupled to the remote device through a connected communication network (e.g., any wired or wireless communication network such as the Internet, 3G network and/or Wireless Local Area Network (WLAN), etc.). The player 100 may further communicate with a remote device through a connected communication network. In some embodiments, the exception reporting module 340 may further detect whether the picture after the troubleshooting module 330 automatically restarts the playing software is normal, and if the picture is normal after the playing software is restarted, it indicates that the fault is cleared. Conversely, if the number of times that the screen is not recovered to normal is detected to exceed a predetermined number of times, the abnormality reporting module 340 may transmit a message indicating that the screen is abnormal and that the fault is automatically removed and invalid to the remote device through the network. For example, when the picture analyzing module 320 detects that the picture is abnormal, the abnormality reporting module 340 will automatically generate an abnormality record to record the start time and the end time of each occurrence of the picture abnormality, and transmit a picture abnormality message to a remote device such as a server through a network to report the picture abnormality to realize the notification of the occurrence of the fault condition, the processor 110 determines whether the picture can be normally played after restarting the playing software, if the picture abnormality occurs 3 times or more continuously within 15 minutes, which indicates that the picture cannot be automatically eliminated, the abnormality reporting module reports a message indicating the picture abnormality and automatically eliminates the invalid picture to the remote device. When the remote device receives the information that the picture is abnormal and invalid is automatically eliminated, the remote device indicates that other fault reasons which cannot be automatically eliminated occur in the digital advertising board, and relevant personnel are dispatched to the site where the digital electronic advertising board is located to inspect and eliminate the fault.
In some embodiments, to further reduce the time required for detecting the frame, the frame analysis module 320 may sample the frame according to a predetermined sampling rate during detecting the frame, and then check whether the sampled pixels are black pixels to determine whether the frame is abnormal. In an embodiment, the step of the picture analysis module 320 detecting whether the picture is abnormal may further include: sampling the current picture according to a sampling rate to obtain a plurality of sampling pixel points in the current picture, judging whether all the sampling pixel points are black pixel points, and automatically executing the automatic fault elimination program when the detected picture is judged to be abnormal.
FIG. 5 is a flowchart illustrating a method for troubleshooting and warning a digital billboard according to an embodiment of the invention. The method for troubleshooting and warning a digital billboard according to an embodiment of the invention can be applied to the digital billboard playing system 10 shown in fig. 1. For example, the method may be performed by the processor 110 of the player 100 shown in fig. 1.
When the processor 110 is ready to perform the frame detection, in step S502, a frame of the digital billboard is sampled according to a sampling rate to obtain a plurality of sampling pixels. For example, the sampling rate may be once every ten pixels, although the disclosure is not so limited.
Next, in step S504, the processor 110 determines whether all the sampling pixels are black pixels. As mentioned above, since each pixel in the black image is a black pixel, the processor 110 can check whether each sampling pixel of the current image is a black pixel through the image analysis module 320, and determine whether the image is abnormal. When all the sampling pixel points are black pixel points, the current picture is possibly a black picture, the detected picture is judged to be abnormal, and when any sampling pixel point is not a black pixel point, the detected picture is judged to be normal.
When all the sampling pixels are black pixels, in step S506, the processor 110 determines that the frame is abnormal, and then automatically restarts the playing software to replay the multimedia information and generate an abnormal record about the abnormal time point and transmit a frame abnormal information to a remote device through a network. Specifically, in response to the frame analysis module 320 detecting that the frame is abnormal (i.e., black frame), the abnormal reporting module 340 will start to generate an abnormal record about the abnormal time point and transmit a frame abnormal message to a remote device via a network. In some embodiments, the exception reporting module 340 may further detect whether the picture after the playing software is automatically restarted by the troubleshooting module is recovered to be normal, and if the picture is recovered to be normal after the playing software is restarted, it indicates that the fault is cleared. On the contrary, if the number of times of continuously detecting that the screen is not recovered to normal exceeds a predetermined number of times, the abnormality reporting module 340 may transmit a message indicating that the screen is abnormal and that the fault is automatically eliminated to the remote device through the network.
The following embodiments are provided to help explain the repairing method of the digital billboard and the method of troubleshooting and warning and the practical application details thereof according to the present invention, but the invention is not limited thereto.
Fig. 6A-6B are flow charts illustrating a method for signal detection and troubleshooting and alerting thereof for a digital billboard in accordance with another embodiment of the invention. The method for signal detection and troubleshooting and warning of the digital billboard according to the embodiment of the invention can be applied to the player 100 shown in fig. 1. For example, the method may be performed by the processor 110 of the player 100 shown in fig. 1. In this embodiment, the processor 110 may control the operations of the monitoring module, the image analysis module, the troubleshooting module, and the abnormality reporting module to perform the signal detection method and the troubleshooting and warning method of the digital billboard, so as to detect whether the image is abnormal and automatically perform troubleshooting when the image is detected to be abnormal.
First, the monitoring processing program of the monitoring module loads a processing program list corresponding to the playback software (step S602) and detects the CPU utilization of one or more processing programs in the processing program list every 30 seconds (step S604). For example, in one embodiment, the playing software may be a media player "Window media player", and the corresponding processing program may be "wmp. Then, the monitoring module determines whether the CPU utilization of all the processing programs under monitoring is zero to determine whether a predetermined condition is satisfied (step S606). In the present embodiment, the predetermined condition is determined to be satisfied when the CPU utilization of all the processing programs is zero, and the predetermined condition is determined not to be satisfied when the CPU utilization of any of the processing programs is not zero.
When the CPU utilization of any processing program is not zero (no in step S606), it indicates that the operation of the playback software is normal, and determines that the predetermined condition is not met, the process returns to step S604, and the monitoring module continues to detect the CPU utilization of one or more processing programs in the processing program list every 30 seconds and determines whether the predetermined condition is met.
When the CPU utilization of all the handlers is zero (yes in step S606), it indicates that there is a possibility of an abnormality in the operation of the playback software, and determines that the predetermined condition is satisfied, and then the monitoring handler of the monitoring module shortens the detection time period, detects the CPU utilization of all the handlers in the handler list every 10 seconds (step S608), and determines whether there are three or more consecutive abnormalities (step S610). Specifically, the monitoring module may record that an abnormality occurs once every time a predetermined condition is satisfied, and thus may determine whether an abnormality occurs three or more times continuously according to the number of times the predetermined condition is satisfied. When the monitoring module determines that the abnormality does not occur more than three times continuously (no in step S610), which indicates that the determination may be an erroneous determination or the screen has recovered to normal, the process returns to step S604, and the monitoring module returns to detect the CPU utilization of one or more processing programs in the processing program list every 30 seconds and determines whether the predetermined condition is satisfied.
When the monitoring module determines that the abnormality occurs more than three times continuously (yes in step S610), the frame analysis module is activated to obtain partial sampling pixels of the current frame by sampling every ten pixels (step S612) and determine whether the sampling pixels are black pixels to determine whether the frame is abnormal (step S614). When all the sampled pixels are not black pixels (no in step S614), the image is normal, and the process returns to step S604, and the monitoring module continues to detect the CPU utilization of one or more processing programs in the processing program list every 30 seconds and determines whether the predetermined condition is satisfied. When all the sampled pixels are black pixels (yes in step S614), it indicates that the current frame is a black frame, and the troubleshooting module is activated and automatically restarts the playing software to play the multimedia information again (step S616). Then, the process returns to step S604, and the monitoring module continues to detect the CPU utilization of one or more of the processing programs in the processing program list every 30 seconds and determines whether the predetermined condition is satisfied.
On the other hand, when all the sampled pixels are black pixels, the exception reporting module is also activated to start an exception reporting operation and generate an exception record, record the time information of the exception occurrence and transmit a message indicating the screen exception to a remote device (not shown) through a network to report the screen exception (step S618). After the playback software is restarted, the monitoring module continues to detect the CPU utilization of one or more of the handlers in the handler list every 30 seconds and determines whether the predetermined condition is satisfied.
The anomaly reporting module counts the number of times of image anomalies and determines whether image anomalies occur 3 times within 15 minutes (step S620). If no screen abnormality occurs for 3 times within 15 minutes (no in step S620), it indicates that the fault has been successfully and automatically cleared, no additional action is required to be executed, the abnormality reporting module is turned off, and the abnormality reporting operation is ended (step S622). If the playback software still has image anomalies for more than 3 times within 15 minutes after the playback software is restarted (yes in step S620), indicating that the playback software cannot be restarted to remove the fault, the anomaly reporting module transmits information indicating that one image is anomalous and that the fault is automatically removed and invalid to the remote device via the network (step S624), and then closes the anomaly reporting module to end the anomaly reporting operation (step S622). When the remote device receives the information that the picture is abnormal and invalid is automatically eliminated, the remote device indicates that other fault reasons which cannot be automatically eliminated occur to the digital advertising board, and relevant personnel are dispatched to the site where the digital electronic advertising board is located to inspect and eliminate the fault. The remote device can be a server or a portable device of a specific person, such as a mobile phone of an engineer near a place where the digital billboard has a fault, and after the remote server receives a fault signal, the remote server can try to remove the fault in a remote control mode or can quickly send a person to the relevant place where the digital billboard is placed to remove the fault, so that the fault can be quickly removed, and the digital billboard is prevented from losing due to the fact that the digital billboard stops playing advertising contents for a long time.
Therefore, according to the method for overhauling the digital billboard and the fault clearing and warning thereof, the processing program used when the playing software is played can be monitored, when the specific action is monitored, the picture analysis module executes the action of detecting the current screen picture, if the picture is black, the abnormal reporting module sends out a notice, the fault clearing module executes the automatic fault clearing process, and reports the result to the abnormal reporting module, thereby the occurrence of the fault condition can be detected immediately, the notice of the occurrence of the fault condition is achieved, the fault clearing and the report of the clearing result are performed when the fault condition occurs, the fault can be cleared immediately and repaired quickly, the manpower is effectively reduced, and the monitoring efficiency of the digital billboard is improved.
