Description

Method for operating observation system

The present invention relates to a monitoring system, and more particularly, to a method of operating a monitoring system for automatically driving the monitoring system according to a predetermined driving pattern and a start / end time.

As the need for crime prevention and security increases, the use of a surveillance system using a closed-circuit TV (hereinafter referred to as "CCTV") is increasing. The CCTV system installs a camera having at least one CCD (Charge Coupled Devices) imaging device in a surveillance region, and reads the video and audio signals applied from the installed camera to recognize a situation occurring in the surveillance region. System. Such a monitoring system has various driving patterns in addition to simply expressing an external situation on a display device. For example, in the case of banks, after the work is completed, surveillance cameras equipped with infrared sensors monitor the inside of the bank and notify the security office by sound or light when an intruder appears, and at night, infrared sensors move people or objects inside the bank. It also detects and notifies you. On the other hand, in such a surveillance system, the security guard controlling the surveillance system must manually select the operation of the surveillance camera and the driving pattern. For example, since bank customers move frequently during business hours of the bank, the surveillance cameras should not detect the movements of customers and generate driving patterns (eg beeps). Only the function of monitoring and recording the area to be monitored should be selected, and the operation pattern of the monitoring system should be turned on when it is determined that there is no movement of people / objects due to the end of the bank's working hours. That is, the conventional surveillance system should always readjust the state of the surveillance system manually according to the business hours, and when the guard who operates the surveillance system fails to readjust the operating pattern of the surveillance system and whether the surveillance camera is on or off, There is a problem that security holes are created.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 shows a block diagram of a schematic configuration of a monitoring system to which the present invention is applied.

The illustrated surveillance system is composed of at least one or more surveillance cameras 10a to 10n, sensors 20a to 20n, a main controller 30, a monitor 40, and a video device 50.

Surveillance cameras 10a to 10n obtain video and audio signals for the installed area and apply them to the main controller 30.

The sensors 20a to 20n do not have an imaging function like the surveillance cameras 10a to 10n, but operate for a predetermined time by the main controller 30 as an infrared / laser sensor for detecting an intruder from the outside. In this figure, the sensors 20a to 20n are driven separately from the surveillance cameras 10a to 10n, but the sensors 20a to 20n can also be mounted and driven on the surveillance cameras 10a to 10n. In this case, the sensor mounted on the surveillance cameras 10a to 10n is preferably an infrared sensor, and the mounted infrared sensor may perform surveillance activities even for a person / object having little movement.

The main controller 30 processes video and audio applied from the surveillance cameras 10a to 10n and the sensors 20a to 20n, reproduces them on the monitor 40 or stores them in the video device 50. In addition, the main controller 30 is driven by a predetermined application program for setting the operation time and driving pattern of the surveillance cameras 10a to 10n and the sensors 20a to 20n, and monitors the predetermined OSD menu. Displayed on to set the drive pattern and the execution time of the drive pattern.

The monitor 40 processes an image signal applied from the main controller 30 and displays the image signal so as to recognize an external situation by looking at the image displayed on the monitor 40.

The video device 50 records a video / audio signal applied from the main controller 30. When the speaker 60 detects an abnormal symptom by the surveillance cameras 10a to 10n or the sensors 20a to 20n, the speaker 60 generates a sound and a warning sound according to the driving pattern.

Preferably, the main control unit 30 has a multiplexer unit 31 and a program storage unit 32, and the multiplexer unit 31 includes a decoder unit 31a, a control unit 31b, an OSD processing unit 31c, and It has a video encoder 31d.

The multiplexer unit 31 receives a video signal and an audio signal output from the surveillance cameras 10a to 10n and processes the same to restore the video and audio. In addition, it controls the driving of each of the surveillance cameras 10a to 10n, and has a multi-display function for displaying the video signal output from each of the surveillance cameras 10a to 10n on one screen.

The decoder 31a receives a video signal output from each of the surveillance cameras 10a to 10n and converts it into a digital signal. The decoder 31a mixes the digital video signals corresponding to the surveillance cameras 10a to 10n and displays the video signals output from the surveillance cameras 10a to 10n on one monitor 40. do. Accordingly, since the monitor 40 displays all the video signals output from each of the surveillance cameras 10a to 10n, it is possible to simultaneously monitor all regions where the surveillance cameras 10a to 10n are installed.

The control unit 31b sets the operating time of the surveillance cameras 10a to 10n and the sensors 20a to 20n by an application program stored in the program storage unit 32, and the surveillance cameras 10a to 10n and the sensor during the set time. The driving pattern in response to the abnormal symptom detected at 20a to 20n is set. In addition, the control unit 31b controls each of the surveillance cameras 10a to 10n to zoom, focus, iris, pan, and tilt the surveillance cameras 10a to 10n. tilt) to control the function. Here, zoom and focus are functions for viewing the monitoring object in more detail, and iris is a function for controlling the aperture according to the ambient light of the surveillance cameras 10a to 10n, and pan and tilt. Refers to a function of moving the lens provided in the surveillance cameras 10a to 10n up / down / left / right to change the imaging positions of the surveillance cameras 10a to 10n.

The OSD processing unit 31c monitors the monitor 40 so that the control unit 31b can set the operation time and the driving pattern of the surveillance cameras 10a to 10n and the sensors 20a to 20n through the monitor 40. Predetermined characters and figures are displayed on the screen.

The video encoder 31d converts the video signal output from the decoder 31a into a format that the monitor 40 or the video device 50 can receive, for example, an NTSC or PAL format. The converted video signal is displayed on the monitor 40 or applied to the video device 50 and stored.

Hereinafter, a method of operating a monitoring system that automatically operates the monitoring system as described above according to a set time and a driving pattern will be described.

Figure 2 shows a flow chart according to a preferred embodiment of the operating method of the monitoring system of the present invention.

First, the main controller 30 sets the operation time and the driving pattern of the surveillance cameras 10a to 10n and the sensors 20a to 20n (S100). The operation time of the monitoring cameras 10a to 10n means a time when the monitoring cameras 10a to 10n are operated for motion detection in addition to the time for the monitoring cameras 10a to 10n to perform a normal monitoring operation. For example, in the case of a bank, the motion detection mode in which the surveillance cameras 10a to 10n detect the movement of people / objects to detect an intruder who invades the bank from the outside after 8 am to 5 pm is finished. It means the time to operate by switching to. In this case, a separate sensor, such as an infrared ray and a laser sensor, may be mounted on the surveillance cameras 10a to 10n to detect motion detection and external intrusion by a sensor mounted thereon.

The driving pattern corresponds to the operation mode and detection of abnormal symptoms of each of the surveillance cameras 10a to 10n and the sensors 20a to 20n. For example, when an abnormal symptom occurs, a security or warning image is used to notify the security officer of external intrusion. The monitoring cameras 10a to 10n and the sensors 20a to 20n can be individually set. The driving pattern setting and the operation time setting for each of the surveillance cameras 10a to 10n and the sensors 20a to 20n are set by the controller 31b driven by an application program stored in the program storage unit 32, and the OSD The processor 31c displays a predetermined menu on the monitor 40 so that such a setting can be easily performed through the controller 31b. This will be described later in detail.

Next, each of the surveillance cameras 10a to 10n and the sensors 20a to 20n operates in general observation, infrared / laser sensing, and motion detection modes, respectively, according to the driving pattern and operation time set by the main controller 30. And, observe the abnormal symptoms from the outside (S200). For example, even in the same time zone, the surveillance camera 10a performs a general surveillance operation, the surveillance camera 10b operates in a motion detection mode, and the sensors 20a to 20n may operate in a turn-off state.

Finally, the controller 31b performs a predetermined driving pattern according to the operation time and displays it on the monitor 40 or outputs it to a voice reproducing apparatus such as a speaker (S300).

3A to 3C show an OSD menu for setting a driving pattern and an operation time.

3A shows a main menu for setting a driving pattern.

The illustrated main menu 100 has a menu 110 for setting an operation time of a driving pattern, and a user setting menu 120 for each driving pattern.

The menu 110 for setting an operation time of the driving pattern sets an operation start time and an operation end time for each driving pattern. In the illustrated menu 110, the driving pattern 1 is operated from 8 am to 17 pm and the driving pattern 2 is operated from 17 pm to 8 am the next day. Here, in the menu 110 for setting an operation time, a driving pattern to be applied for each time zone may be selected. In the drawing, the driving pattern 1 is set from 8:00 am to 7:00 am, and the driving pattern 2 is set from 17 pm to 8:00 am the next day, but the driving pattern is not fixed for each time zone and can be changed. . In the present embodiment, a menu for setting two driving patterns is illustrated, but three or more driving patterns may be set by subdividing time zones.

On the other hand, when a signal line connecting the surveillance cameras 10a to 10n and the control unit 31b is cut by an intruder from the outside, no video signal is reproduced in the monitor 40, which is usually a video loss. In the menu, the driving pattern 2 is set. In this case, when a video loss occurs, a warning sound is generated from the speaker 60 to notify the guards. Here, the setting of the menus 110 and 120 may be performed by a remote control device (not shown) for driving an OSD menu or a setting key (for example, a direction key, an enter key, and an ESC key) attachable to a main control unit. .

3B illustrates a submenu of the driving pattern 1 illustrated in FIG. 3A.

The illustrated submenu has channels CH1 to CHn, which refer to respective surveillance cameras 10a to 10n, function setting menus 130 for each channel CH1 to CHn, and respective function setting menus 130 ) Has a motion detection menu 131, a warning sound menu 132, and a general monitoring menu 133.

Each of the surveillance cameras 10a to 10n corresponds to channel 1 (CH1), channel 2 (CH2), and channel n (CHn), and the function setting menu 130 performs motion for each channel (CH1 to CHn). Select whether to operate in the detection mode, generate a warning sound, or normal operation mode.

FIG. 3C illustrates a submenu of the driving pattern 2 illustrated in FIG. 3A, and typically illustrates an embodiment of the driving pattern from 17 pm to 8 am of the next day. As shown, the surveillance cameras 10a to 10n mainly operate in the motion detection mode, and the sensors 20a to 20n are set to generate a warning sound. 3A and 3B, the monitoring system according to the present invention does not require an additional manual setting for 24 hours since the menu is repeatedly set by the user until the menu is set and reset. In addition, since the surveillance system operates automatically according to the set time and driving pattern, the security guard who operates it does not need to manually switch the settings for the surveillance cameras 10a to 10n and the sensors 20a to 20n.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the present invention is not limited to the specific embodiments of the present invention without departing from the spirit of the present invention as claimed in the claims. Anyone of ordinary skill in the art can make various modifications, as well as such changes are within the scope of the claims.

As described above, according to the present invention, since the monitoring system operates automatically 24 hours according to the set time and driving pattern once, the monitoring system does not malfunction due to a mistake of the security guard and does not need to manually set the time and monitoring mode.
