4 is a schematic diagram showing a remote monitoring system of a digital surveillance device according to the present invention in which a digital video monitoring terminal and a remote monitoring device for remote monitoring the monitoring terminal shown in FIG. 1 are connected through a data communication network.

In the drawing, a plurality of digital video monitoring terminals 10 shown in FIGS. 1 to 3 are connected to a remote monitoring apparatus 400 via a data communication network 300.

According to the functional block configuration of the remote monitoring apparatus 400 shown in FIG. 5, the main control unit 410 has overall control related to the event generation of the digital video monitoring terminal 10 by the corresponding remote monitoring apparatus 400. Will run.

The data communication unit 412 is connected to each digital video monitoring terminal 10 via the data communication network 300 to receive event status information transmitted from each digital video monitoring terminal 10 to the main control unit 410. Will be delivered.

In addition, in the remote monitoring apparatus 400, the data input unit 414 is configured to include, for example, a keyboard and a mouse to instruct setting and execution of a specific function for the main control unit 410.

The operating program storage unit 416 stores an operating program including a processing procedure for the event state of the digital video monitoring terminal 10 executed by the main control unit 410, and the monitoring terminal information storage unit 418. Information stored in the digital video monitoring terminal 10 (for example, position or alarm setting information, etc.) connected through the data communication network 300 is stored in the monitoring terminal event storage unit 420. Event occurrence image screen data transmitted from) is stored.

In addition, in the remote monitoring apparatus 400, the monitoring screen driver 422 forms an image screen for monitoring the status of each monitoring terminal 10 under the control of the main controller 410 and displays it on the display unit 424. In addition, when an event occurs in a specific monitoring terminal 10, a process of enlarging and displaying the video screen from the monitoring terminal 10 is performed on any one of the plurality of auxiliary display units 424a to 424n.

That is, an icon 426a corresponding to each monitoring terminal 10 is displayed on the display unit 424, and information related to the occurrence of an event is transmitted from the specific monitoring terminal 10 to the sub display units 424a to 424n. The basic information (eg, location or alarm condition) of the monitoring terminal 10 where the event is generated is displayed, and the video screen 424a transmitted from the monitoring terminal 10 is enlarged to display the situation of the event. Observation becomes possible.

According to the operation of the digital video surveillance system according to the present invention of the above configuration, the monitor using a keyboard or mouse (and / or jog shuttle or remote controller) constituting the data input unit 70 of the monitoring terminal 10 When the icon 150 related to the alarm registration / change of 144 is selected, an alarm registration or alarm change screen is displayed on the monitor 144 under the control of the controller 60.

On the alarm registration or alarm change screen, alarm execution items (for example, ① warning light, ② alarm buzzer, ---, ⓝ call number xxx-xxx-xxxx) are registered.

Then, the control unit 60 gives priority to the alarm execution item of the registration target and stores it in the operation data memory 100 (step 500 of FIG. 7A).

Under the state in which the alarm execution item is registered, the controller 60 determines whether the weekly monitoring mode is set by the mode setting key 50a of the mode setting unit 50.

As a result of the determination, when the weekly monitoring mode is set (that is, YES in step 502 of FIG. 7A), the controller 60 executes the monitoring terminal 10 in the weekly monitoring mode (step 504 of FIG. 7A). In the weekly monitoring mode, the first image monitoring unit 20 is activated under the control of the control unit 60.

That is, in the weekly monitoring mode, the first imaging controller 22 of the first video monitoring unit 20 is activated, and the first to nth color video cameras 24a to 24n are activated, and the first imaging is performed. The controller 22 scans an image screen captured by the first to nth color video cameras 24a to 24n and applies the scanned image screen to the controller 60.

Accordingly, the control unit 60 allows the video screen applied from the first to nth color video cameras 24a to 24n to be stored in the surveillance data memory 110 and the image distribution unit 142. Through the monitor 144 is displayed in the form illustrated in FIG.

In such a state, if the occurrence of the field event is not detected by a specific color video camera (eg, 24a) (i.e., No in step 506 of FIG. 7A), the controller 60 determines whether the emergency button 52 is operated. If the emergency button 52 is operated (YES in step 507a of FIG. 7A), the control unit 60 transmits an alarm corresponding to the operation of the emergency button 52 as a top priority. The transmission of is preferably done via the alarm transmitter 120, for example to a police station / police box or security company (step 507b of FIG. 7A).

In contrast, when the occurrence of the field event is detected (i.e., YES in step 506 of FIG. 7A) (e.g., detection due to a difference in the image pattern comparison result with the video screen of the preceding frame), the control unit 60 determines that The image screen captured by the color video camera 24a is displayed on the monitor 144 through the image distribution unit 142, and the alarm is based on the alarm execution items stored in the operation data memory 120. Alarms are sequentially generated through the transmitter 120 to notify the manager of the occurrence of an event (steps 508 and 510 of FIG. 7A).

In addition, even when a screen for the video camera 24a is selected, the controller 60 causes the video screen to be enlarged on the monitor 144.

During the weekly monitoring mode, the alarm set by the alarm transmitter 120 is executed even when a situation such as a fire or an impact is detected by the detection sensor groups 46a to 46n. do.

In such a state, for example, when the emergency button 52 is operated, an alarm is executed first and foremost, an immediate notification is made to a security center including, for example, a police station or police box.

While the weekly monitoring mode is in progress, the controller 60 checks the mode change to the night monitoring mode. For example, the administrator sets the night mode by the mode setting key 50a of the mode setting unit 50. If set (ie, YES in step 512 of FIG. 7A), the control unit 60 switches the first image monitoring unit 20 to the inactive state while the second image monitoring unit 30 and the event detection sensor are inactive. Part 40 is activated (step 514 of FIG. 7A).

Therefore, in the night monitoring mode, the second image control unit 32 of the second image monitoring unit 30 activated under the control of the control unit 60 controls the first to nth monochrome video cameras 34a to 34n. The sensor control unit 42 of the event detection sensor unit 40 activates the first to nth human body detection sensors 44a to 44n and the monitoring sensor group 46a to 46n.

In such a state, when the occurrence of an event is detected by the first to nth monochrome video cameras 34a to 34n, the controller 60 controls the alarm transmitter 120 similarly to the weekly monitoring mode. The alarm execution items registered by driving are sequentially executed, and specific field events (eg, unauthorized intrusion, fire, ---, gas) are performed by the human body sensor 44a to 44n or the monitoring sensor group 46a to 46n. Even if a leak, an impact caused by damage of a window or a door, etc.) occurs, the registered alarm execution items are sequentially executed.

Here, the alarm execution item for the event can be set differently for the daytime monitoring mode and the night monitoring mode.

On the other hand, when an emergency event occurs for the monitoring terminal 10, that is, the commercial AC power applied to the power supply unit 82 of the corresponding monitoring terminal 10 is cut off (for example, by deliberately removing or disconnecting the AC plug). Is detected by the power state detection unit 88, or any of the monochrome video cameras 34a, ---, 34n configured in the second image monitoring unit 20. Is not applied to the video signal or a basic signal is not detected from the human body sensor 44a to 44n and the sensor group 46a to 46n of the event sensor 40, or the state detector 90 Is attempted to move or cut the monitoring terminal 10 without inputting a valid password, thereby detecting a status detection signal S / W from the state detection unit 90 (i.e., YES in step 516 of FIG. 7B). The controller 60 indicates the emergency event occurrence situation. The remote monitoring apparatus 400 to output information and image screen data stored in the surveillance data memory 110 through the data communication network 300 via the wired or wireless LAN 130a from the state transmitter 130. Will be sent to the side.

Here, the transmission of the video screen stored in the surveillance data memory 110 is prioritized to the last video screen data stored in the surveillance data memory 110 until the backup power 84 as the emergency power supply is exhausted. Transmission is performed in reverse order (step 518 of FIG. 7B).

In addition, the controller 60 executes the alarm by driving the alarm transmitter 120 based on the registered alarm execution item.

In the night monitoring mode, the screen display by the main monitor 144 by the video distribution unit 142 may not be performed in order to save power when the manager is not arranged.

A separate power source is applied to any one of the first to nth monochrome video cameras 34a to 34n and to any one of the first to nth human body detection sensors 44a to 44n of the event detection sensor 40. Even when the power supply to the corresponding monitoring terminal 10 is cut off (for example, when the power plug is removed or the power line is disconnected), the image of the field is captured and the control unit 60 operated by the backup power source 84 is operated. The control may be transmitted to the remote monitoring apparatus 400 through the data communication network 300.

On the other hand, the present invention is not limited to the above embodiments, and various changes and modifications can be made within the scope not departing from the technical gist and gist of the invention. For example, in the mode setting unit 50, the mode setting key 50a for selecting the daytime monitoring mode and the nighttime monitoring mode is displayed on the monitor in the form of a mode setting icon so that the change of the daytime / nighttime monitoring mode is performed. It may be made.

When changing from the night monitoring mode to the daytime monitoring mode or from the daytime monitoring mode to the nighttime monitoring mode, the specific password number is registered in advance in the operation data memory 100 under the control of the controller 60 and the mode is changed. At the time, the mode change is made only when the password number is input by forming an input window of the password number on the main monitor 144, while inputting the correct password number for a predetermined number of times (for example, three times). If this is not done, the registered alarm execution items may be executed sequentially.

As described above, according to the digital video remote monitoring and emergency detection system according to the present invention, the video camera for recording the video screen in the daytime monitoring mode and night monitoring mode for the monitoring terminal is composed of color and monochrome (B / W) Therefore, it is possible to provide an optimal video screen according to the day / night monitoring mode.

In addition, for events occurring on the monitoring terminal itself (main power cut off, abnormal disconnection of the video signal, abnormal movement / cutting of the main body, etc.), the data communication network is reversed from the current video screen to the integrated remote monitoring device of the remote site. As it is transmitted and displayed, continuous and real-time confirmation of on-site events and emergency events of the monitoring terminal main body and on-site record preservation and post-processing can be executed quickly even in the event of the worst event.
