Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
The invention provides a network monitoring system, which can send out warning signals through a display device of a user and achieve instant notification according to the use situation of the user. FIG. 1 is a schematic diagram of a network monitoring system 10 according to an embodiment of the present invention. As shown in fig. 1, the network monitoring system 10 may include a display device 100, an image providing unit 101, a router 200, and one or more webcams 300. The image providing unit 101 is connected to the display device 100, and can transmit the local video to the display device 100. On the other hand, a plurality of webcams 300 are connected to the router 200, and the router 200 is connected to the display device 100. Different webcams 300 can capture different areas to generate monitoring video. Each web camera 300 transmits its surveillance video to the display device 100 via the router 200 in areas such as gate entrances and exits, parking lots, and the like. The monitoring video is transmitted to the display device 100 for viewing by the user.
The display device 100 can convert the network signal from the network camera 300 into the monitoring video. The user can view a plurality of monitoring pictures on the display device 100, the invention can also convert the network signal into monitoring video signal, and then input the monitoring video signal by the audio-video terminal (such as HDMI interface) of the display device 100, and under some conditions, a single network camera 300 can be used, and at the moment, the router 200 is not needed and the received signal can be directly transmitted to the display device 100. The display device 100 may further have a plurality of audio/video input terminals, and one of the input terminals may be selected to connect to the image providing unit 101 (such as a DVD player, a PC or a game machine), so that the display device 100 may have a function of generally using a display in addition to a monitoring function.
Fig. 2 is a schematic diagram of an embodiment of the display device 100. As shown in fig. 2, the display device 100 includes a screen 103, a processing device 110, and a display operation device 120. The display device 100 can receive the local video V1 and the monitor video V2 simultaneously through an external interface (such as HDMI, VGA or RJ45), and then a user selects one of the videos as a display screen to be displayed on the screen. The processing device 110 receives the monitoring video V2 and determines a notification message according to the comparison and analysis of the images, the content of which includes the priority and the type of the abnormal condition, and the processing device 110 further determines an alarm signal a according to the notification message and an alarm rule; the display operation device 120 may be a scaler (scaler), which receives the local video V1, the monitor video V2 and the alarm signal a, and determines the image to be displayed on the screen 103 according to the alarm signal a.
In other examples, the display device 100 may be a tablet computer or an All In One PC (All In One PC), and the native video V1 may be generated by the display device 100. In other words, a display device incorporating an image providing unit may be employed. The processing device 110 processes the monitor video V2 and sends it to the display computing device 120. For example, the processing device 110 decodes the surveillance video V2 and combines multiple surveillance videos V2 from different webcams 300. Whether to generate the notification message is determined according to the monitoring video V2 and the preset comparison condition.
In one embodiment, the notification message is generated by the processing device 110 according to the comparison condition. The comparison condition is, for example, an abnormal condition such as a person or an animal entering, a camera lens being shielded, and the like. When the processing device 110 finds abnormal situations such as intrusion of people, lens shielding or intrusion of animals after image processing and comparison of signals, a notification message is generated. The processing device 110 generates an alert signal A according to the notification message and the alert rule. The alert rule may include, for example, a correspondence between a usage context and a notification message. In other words, the processing device 110 can determine which abnormal condition is the abnormal condition from the notification message, and generate the warning signal a according to the warning rule.
Referring to the embodiment of table one, two usage scenarios of the screen display monitor screen and the screen display local screen are defined in the alert rule, and the notification message may have priority and abnormal status such as: there are three abnormal situations of personnel intrusion, lens shielding and animal intrusion. The first two abnormal conditions have a high priority level, while the condition of animal intrusion is a low priority level. When the abnormal condition occurs, the warning signal A generated according to the notification message and the warning rule comprises a command for carrying out screenshot. In the first table, the high priority level may be used to capture the screen shot by the network camera 300 in which the abnormal condition occurs with low transparency and then cover the captured screen with low transparency, while the low priority level may be used to display the captured screen on the monitor screen or the local screen with higher transparency after capturing the screen, so as to avoid interfering the user to view the screen being watched.
On the other hand, the usage scenario may include, for example, an amount of operation load of the display operation device. In other words, the two usage scenarios can be distinguished according to the operation load of the display operation device. For example, when displaying the local video, the display operation device 120 performs a relatively large amount of image processing or operation, so that the operation load amount when displaying the monitoring screen is smaller than the operation load amount when displaying the local screen, and therefore, when determining that the user is viewing the local video, in the first place, under the abnormal condition that the animal intrudes, the screenshot display with high transparency is used to avoid too much influencing the concentration of the user, and when determining that the user is viewing the monitoring screen, the screenshot window with medium transparency can be displayed; in some situations, even if the video of the local computer is displayed, the operation load may have different levels, for example, the fast moving and still pictures of the picture will have different effects on the operation load, and in this state, the warning rule may set different rules according to different operation loads, for example, the transparency of the screenshot may be adjusted corresponding to the operation load.
(watch one)
It should be added that the above-mentioned screenshot refers to the screenshot generated according to the monitored video. Returning to FIG. 2, in particular, the display computing device generates the local screen and the monitoring screen according to the local video and the monitoring video. The warning signal A can comprise a screenshot request, the display arithmetic device generates a screenshot picture from the monitoring video according to the screenshot request, and a composite picture of the screenshot picture is combined on the picture when the local picture or the monitoring picture is displayed, so as to remind a user of the abnormal condition.
Fig. 3 is a schematic diagram of another embodiment of the display device 100. As shown in fig. 3, the display device 100 includes a processing device 110 and a display operation device 120. The display computing device 120 receives the native video V1 and the surveillance video V2. The processing device 110 processes the monitor video V2 and sends it to the display computing device 120. Whether to generate the notification message is determined according to the monitoring video V2 and the preset comparison condition.
In one embodiment, the notification message S is generated by the web camera 300 performing image processing on the captured image according to the comparison condition. For example, the web camera 300 finds an abnormal condition after image recognition, and accordingly generates the notification message S and transmits the monitoring video V2 to the display device 100 at the same time. As shown in FIG. 3, the processing device 110 includes an event handler 112 configured to parse the notification message and generate an alert signal A according to the notification message and the alert rule.
Referring to table two, the alert rule may include two usage scenarios, i.e. displaying the monitor screen and displaying the local screen, and the notification message may have priority and abnormal status, such as: there are three abnormal situations of personnel intrusion, lens shielding and animal intrusion. These three exception conditions have different priority levels. When an abnormal condition occurs, screenshots with different effects can be generated according to the warning rule. For example, an abnormal condition with a high level may generate a screenshot effect with low transparency or without reducing transparency, so that the user may perceive the abnormal condition, an abnormal condition with a medium level may generate a screenshot effect with medium transparency, and an abnormal condition with a low level may generate a screenshot effect with high transparency, so as to avoid blocking the image currently being viewed by the user.
(watch two)
Taking fig. 3 and table two as an example, the alert signal a includes a screenshot request. The screenshot request includes transparency adjustment corresponding to different priority levels to generate a screenshot having transparency different from transparency of the local screen and the monitored screen. For example, in table two, an abnormal condition with a high level may correspondingly generate a screenshot with the lowest transparency, so as to clearly remind the user of the occurrence of an abnormal event. The display computing device 120 generates a screenshot from the monitoring video V2 according to the screenshot request, and forms a composite frame having the screenshot combined with the local frame or the monitoring frame.
Fig. 4, 5 and 6 are schematic diagrams of different warning manners. As shown in FIG. 4, when the user is in the test game, the display computing device displays a local screen P1 on the display device 100 according to the local video. When a person intrudes, the processing device generates an alarm signal A. The display computing device generates a screenshot Q1 from the surveillance video with low transparency (represented by dots) based on the screenshot request. In the embodiment of fig. 4, a composite screen is formed of the screenshot screen Q1 and the native screen P1. The screenshot image Q1 is superimposed on the local image P1. In other examples, the transparency of the screenshot picture Q1 and the native picture P1 may be the same.
As shown in FIG. 5, when the user is in the test game, the display computing device displays a local screen P1 on the display device 100 according to the local video. When the lens is shielded, the processing device generates an alarm signal A. The display computing device generates a screenshot Q1 from the surveillance video with medium transparency (shown with diagonal lines) based on the screenshot request. In the embodiment of fig. 5, a composite screen is formed of the screenshot screen Q1 and the native screen P1. The screenshot image Q1 is formed on the local image P1 in an overlapped manner, and the screenshot image Q1 has a different transparency from the local image P1, because the user has a high computational load during the test game, and when an abnormal condition occurs, the user may want to see the local image P1, so that the transparency of the screenshot image Q1 can be increased, and the user can still see the local image P1.
As shown in fig. 6, when the user views the monitoring screen, the display operation device displays the monitoring screen on the display device 100 based on the monitoring video (P21, P22, P23, P24). When an animal intrudes (such as the monitoring picture P23), the processing device generates an alarm signal A. The display computing device generates a screenshot Q1 from the surveillance video according to the screenshot request. In the embodiment of fig. 6, a composite screen is composed of the screenshot screen Q1 and the monitoring screens (P21, P22, P23, P24). The screenshot screen Q1 is superimposed on the monitoring screen (P21, P22, P23, P24). The transparency of the screenshot Q1 in fig. 6 is higher than the transparency of the screenshots in fig. 4 and 5.
Fig. 7 is a schematic diagram of another embodiment of the display device 100. As shown in fig. 7, the display device 100 further includes a screen camera 130 and a bluetooth receiving device 140 in addition to the processing device 110 and the display operation device 120. The screen camera 130 and the bluetooth receiving device 140 serve as sensing devices to determine whether the user is in front of the display device 100. The processing device 110 processes the monitor video V2 and sends it to the display computing device 120. The display operation device 120 receives the local video V1 and the monitor video V2, and the user selects one of the videos to be displayed on the screen 103. Whether to generate the notification message is determined according to the monitoring video V2 and the preset comparison condition. In addition, the processing device 110 includes an event processor 112 configured to parse the notification message and generate an alert signal A according to the notification message and the alert rule.
In one embodiment, the screen camera 130 may face the same direction as the display surface, for example, so as to know whether the user is in front of the display device. For example, the size of the image obtained by shooting is used to determine whether the user is within 1 meter of the front of the display device. The bluetooth receiver 140 may be, for example, a positioning signal receiver using bluetooth low energy technology, which can detect bluetooth signals of a user's mobile phone or a wearable device. Thereby determining whether the user is in front of the display device. In general, the sensing device is configured to sense whether a user is in front of the display device to generate a sensing result, and determine a usage situation and an alert rule according to the sensing result.
In addition, as shown in fig. 7, the network monitoring system further includes an input device 400 in addition to the display device 100. The input device 400, such as a keyboard or a mouse, is connected to the display device 100. The input device 400 has a switching service. When the switching service is triggered, the display operation device 120 switches and displays the local screen, the monitoring screen or the composite screen. The switching service can be, for example, Display Data Channel/Command Interface (DDC/CI), which is a communication protocol that can change the way of displaying information on the Display device through a keyboard or a mouse. For example, the keyboard can set shortcut keys by switching services, when the user leaves the display device and is informed of abnormal conditions, the user can trigger the switching services by key operation before returning to the display device, so that the display operation device is switched from the local picture to the composite picture.
In other examples, when the user executes other tasks before the display device and the popped screenshot picture informs that there is an abnormal condition, the user can trigger the switching service through the key operation, so that the display operation device cancels the screenshot picture superimposed on the local picture in the composite picture and returns to the local picture, and presses the shortcut key again to switch the screenshot picture and the monitoring picture displayed in a picture-in-picture manner. Therefore, the user can quickly switch to the required watching mode.
Referring to table three, as shown in table three, the warning rule defines three use situations, namely, displaying the monitoring screen, displaying the local screen, and leaving the display device for the user, and defines three abnormal situations, namely, intrusion of a person, lens shielding, and intrusion of an animal. These three exception conditions have different priority levels. Generally, the warning rule includes a combination of a plurality of corresponding relationships, such as a corresponding relationship between the notification message and the operation load of the display operation device, and a corresponding relationship between the notification message and whether the user leaves the display device. When an abnormal condition occurs, for example, a screenshot or warning tone with different effects may be generated according to the warning rule.
Further, the alert rule may set at least one alert action for each usage scenario and abnormal condition, for example, a combination of different alert actions. As shown in table three, four warning actions (screen shot, text, warning sound, and warning light) or one warning action (screen shot) are set at different priority levels for viewing the usage situation of the monitoring screen in the warning rule. For the use situation of viewing the local picture, three warning actions (screenshot, character and warning light) or one warning action (character) are respectively set at different priority levels. In the case of leaving the display device, two warning actions (warning sound and warning light) are set for the high level and the low level, respectively, and one warning action (warning sound) is set for the low level.
For example, the different warning tones in table three may be set as: the warning sound a1 is a continuous short tone and is a high volume, the warning sound a2 is a trilong tone and is a medium volume, and the warning sound A3 is a voice broadcast. The priority level is a difference in warning effect, and for example, when the user views the monitor screen, the abnormal condition of the high level causes effects such as a low transparency screen shot, characters, warning sound a1, warning light B1, and the like. When the display device is left, the abnormal condition with the grade of middle generates a warning sound A2 and a warning light B2.
In addition, the different warning lights in table three can be set as: the warning light B1 is a flashing red light, and the warning light B2 is a flashing green light. Besides the light color, the warning light can also be set to different flashing frequencies.
(watch III)
Taking fig. 7 and table three as an example, the warning signal a includes a voice prompt request. As shown in fig. 7, the display device 100 includes a sound controller 150 connected to a speaker device 160. The warning signal A includes an audio prompt request. The voice prompt request includes warning tone adjustment corresponding to different priority levels. The audio controller 150 receives the audio alert request to generate various alert tones at the microphone device 160. In addition, the alert signal a may include a screenshot request. The processing device 110 generates the warning signal a according to the warning rule corresponding to different abnormal conditions, and the warning signal a may be a warning sound or a combination of the warning sound and other warning actions.
In addition, taking fig. 7 and table three as an example, the warning signal a includes a light-emitting prompt request. As shown in fig. 7, the display device 100 includes a light source controller 170 connected to a peripheral light source 180. The warning signal A includes a light-emitting prompt request. The light-emitting prompt request corresponds to different priority levels and comprises warning light adjustment. The light source controller 170 receives the light-emitting prompt request to generate different warning lights at the peripheral light source 180. In addition, the warning signal a may include an audio prompt request or a screenshot request. The warning signal a generated by the processing device 110 according to the warning rule may be a warning sound generated together with the warning light or a warning sound generated separately.
For text based alerts, for example, the alert signal further comprises a text prompt request. Referring to fig. 7 and table three, the processing device 110 includes a screen controller 114. The warning signal A includes a text prompt request. The text prompt request may generate corresponding event descriptions corresponding to different priority levels. The frame controller 114 generates an alert text describing the detected abnormal condition according to the text prompt request. The display computing device 120 receives the warning text transmitted from the screen controller 114, and forms a text prompt screen with the warning text superimposed on the local screen or the monitoring screen. For example, when viewing the monitoring screen, an abnormal situation (occurrence of a human intrusion) with a high level may generate a warning character of "human intrusion" and superimpose the warning character on the monitoring screen on which the human intrusion is captured.
As mentioned above, the alert rule sets a combination of different alert actions. In other words, the alert signal a may include a text prompt request, an audio prompt request, a light prompt request, and/or a screenshot request. The warning signal a generated by the processing device 110 according to the warning rule may be generated by capturing a picture, text, warning sound and warning light together, or only one of the warning actions. In general, the processing device 110 can generate the alert signal a having a configuration corresponding to the corresponding relationship (i.e. the notification message corresponds to the usage situation) according to the alert rule. In other words, the alarm signal a has a different configuration, which includes at least one alarm action, as shown in table three above. For example, the processing device 110 detects that the display operation device 120 is low and detects a notification message with a high corresponding level, and the generated alert signal a has a first configuration including four alert actions. For another example, the processing device 110 detects that the user leaves the display device 100 and detects a notification message corresponding to a level of being in the middle, and the generated alert signal a has a sixth configuration including two alert actions.
Fig. 8 is a schematic diagram of another embodiment of the warning method. As shown in fig. 8, the user leaves the display device 100. When an abnormal condition occurs, the processing device knows that the user leaves the display device 100 according to the image shot by the screen camera 130, and generates an alarm signal a according to the alarm rule. The display and operation device generates a warning sound through the sound amplification device 160 according to the voice prompt request. Thereby allowing the user to immediately detect the abnormal condition.
Fig. 9 is a schematic diagram of another embodiment of the warning method. As shown in FIG. 9, when the user is in the test game, the display computing device displays a local screen P1 on the display device 100 according to the local video. When a person intrudes, the processing device generates an alarm signal A. The display computing device generates a screenshot Q1 from the surveillance video according to the screenshot request. Meanwhile, according to the text prompt request, the screenshot picture Q1 displays the warning text W1 and the number of the web camera. In addition, a warning sound is emitted from the speaker 160 according to the sound prompt request and the light prompt request, and a warning light is emitted from the peripheral light source 180.
In the embodiment of fig. 9, a composite screen is formed of the screenshot screen Q1 and the native screen P1. The screenshot screen Q1 is formed on the local screen P1 in a divided display manner. The peripheral light source 180 is disposed to face the same direction as the display surface, but is not limited thereto. In other embodiments, the perimeter light source 180 is disposed facing a different direction than the display surface, such as on the back of the display surface. Thus, when the user leaves the display device 100, the user can immediately detect the abnormal condition. On the whole, by using the network monitoring system of the invention, different warning modes can be generated according to the type of the abnormal condition and the activity condition of the user on the display device, thereby achieving the effect of immediate warning.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
