Description

Security system capable of voice command control and method thereof

The present invention relates to a security system for monitoring the inside of the security area, and more particularly to a security system and a method for controlling the operation of the surveillance camera through the voice.

As society expands and becomes more complex, the importance of safety is growing, and societal demand for safety systems is increasing. In the past, the subject for solving the safety problem was a government agency, but now it is gradually changing, led by private organizations. In fact, there is a growing demand for the installation of a safety system that requires a separate fee to protect the safety of the family and the property owned by them, more actively, beyond the protection of the government. Typically, security systems installed in homes or buildings are installed at specific locations in homes or buildings and are used to prevent damage from outsider intrusion, fire or flooding. Such security systems are known as 'Control and Method of Security System' of Publication No. 1998-041596, filed on November 30, 1996 and 'Centralized Visitor Monitoring System' of Patent 0178717, filed on April 15, 1994. It has already been filed by name.

However, the conventional security system is generally used to perform the mode of the security system using a card from the outside. Therefore, if you want to cancel the security mode outdoors and enter the indoors, there was a hassle to enter the security card to the security card reader. In addition, security card and security card reader had to be equipped, but the security card was a great risk of loss. On the other hand, as another conventional security system, there is a method for transmitting the visitor's video signal to the central control unit along with the audio signal when the visitor bell or visitor in the absence of the resident is detected by the surveillance camera installed in the guard area. The central control device receives the visitor's video signal and audio signal, and transmits the administrator's audio signal to the personal monitoring device so that the personal monitoring device and the central control device can communicate with each other. The central control apparatus stores the received visitor image signal and the audio signal so that the visitor can be checked later according to the needs of the residents.

On the other hand, such a security system is very useful not only for general households, but also for mountain areas, military special security areas, coasts, ports, airports, dams, and the like. Compared to general households, the above-mentioned regions have a wider scope of expense and more variable data due to the surrounding environment. For example, a number of animals frequently appear in the military special security area. In the case of a small animal, it is easy to identify the human, but in the case of a large animal, it is mistaken as a human. In addition, in mountainous or coastal areas, it is difficult to accurately identify objects due to snow, rain, and fog, and airports are also very difficult to identify people who actually cause crime as a place where many people visit.

In particular, mountainous and coastal areas need to minimize casualties from natural disasters such as wildfires or tsunamis, and military special security areas are responsible for national security. In addition, the airport is a place where exchanges are made between countries, and the safety system at the airport is so important that the safety system of the airport influences the image of the country. Thus, there is an increasing demand for an improved security system that can monitor such a wide range of critical areas more quickly and accurately.

Accordingly, it is an object of the present invention to provide a security system and method that can more quickly and accurately monitor the interior of the security area.

It is another object of the present invention to provide a security system and method for more quickly and accurately monitoring a wide range of security zones.

In order to achieve the above objects, in the present invention, a monitoring computer that is capable of Internet communication, connected to the management computer unit for monitoring and photographing the situation in the security area, and transfers the photographing data to the management computer In the security system including a central control unit for remotely controlling the operation of the surveillance camera for monitoring the inside of the guard area receiving the data of the management computer unit and the last management computer unit; The surveillance camera unit provides a security system, characterized in that the remote control in accordance with the voice command issued from the central control unit.

In addition, in the present invention, in order to achieve the above objects, the management computer unit capable of Internet communication, connected to the management computer unit for monitoring and photographing the situation in the guard area, and transfers the shooting data to the management computer Claims [1] A security method using a security system comprising a surveillance camera unit and a central control unit for remotely controlling an operation of a surveillance camera for monitoring the inside of a security zone by receiving data of the management computer unit.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a security system to which a surveillance camera with a suppression apparatus is applied according to the present invention.

Referring to the drawings, a plurality of surveillance cameras 1, 2 ... N (1) are connected to the management control unit 2, and the management control unit 2 includes a data storage unit 3 and a data output unit 4; ), The controller base 5 is connected. In addition, the management control unit 2 is connected to the central control unit 7 through the Internet network (6), the start control unit 8 and the fire / medical support unit 9 is connected to the central control unit (7) It is. In addition, the central control unit 7 is connected to the voice control unit 10 transmits the various commands necessary for monitoring in the security zone to the surveillance camera (1).

The surveillance camera 1 tracks and photographs an outsider who has invaded the security zone and transmits the data to the management control unit 2, and the data transmitted to the management control unit 2 is centrally controlled through the Internet network 6. Is sent to the unit 7. In this case, the data is photographing data of an external intruder, and becomes important data identifying the identity of the outsider. Then, the data transmitted to the management computer 2 is stored in the data storage unit 3, and if necessary, the data stored in the data storage unit 3 is output in accordance with the command of the central control unit (7). do. If, as a result of analyzing the data tracked and photographed by the surveillance camera (1), and it is determined that the outsider's identity is not an intrusion, it is appropriate to control the external intruder through the central control unit (7). Control measures are taken. That is, when the central control unit 7 transmits a command for controlling an external intruder to the management control unit 2 through the Internet network 6, the control unit 5 connected to the management control unit 2 can be used. Control measures are taken. For example, a gas gun or an electron gun, which can obtain a temporary control effect, is operated to control an external invader and to issue a start command to the start standby section 8. If the security system is used in military operations, appropriate control measures can be taken accordingly. However, as a result of analyzing the data tracked and photographed through the surveillance camera 1, a means for extinguishing the fire early through the controller base 5 is mobilized in the case of a disaster such as a fire that is not an external intruder. . In other words, by operating the fire-fighting device to ignite the fire of the fire, water, fire, or powder fire to premature extinguish fire. In addition, fire / medical support unit 9 is dispatched to minimize casualties and property damage.

As the surveillance camera 1, a photographing equipment that can be connected to the Internet such as a web camera can be used. The surveillance camera 1 is equipped with a zoom function of up to 30KM and a 360-degree rotation function to control and monitor intruders in a wide range of security zones, and to protect the environment, such as small animals, leaves, grass, rain or snow, The object recognition ability is excellent even under weather change conditions such as fog. In addition, it is possible to operate between minus 40 degrees and 60 degrees, and the visibility distance when the fog, rain, and snow obstructs the view is about 100 to 150 meters, and the clear distance on a clear day is about 360 meters. In addition, it is equipped with an infrared and a thermal sensor, it is possible to detect the outside intrusion approach in the guard area of about 400 meters or more, and when the outside invasion approach is detected, the direction of the surveillance camera 1 is directed toward the intruder. In addition, by detecting accidents such as fires in the guard area, it minimizes the damage to life and property due to natural disasters. The surveillance camera 1 is preferably installed at one or more places suitable for detecting and tracking the outside invasion in the guard area. Therefore, when an outsider enters the guard zone, the camera is outside the shooting range of the first surveillance camera. Keep track of intruders. On the other hand, by attaching the surveillance camera (1) to the rail may be formed to move the place, in this case there is a burden to install the rail, but one surveillance camera to effect the effects of several surveillance cameras There is an advantage that can be obtained.

In particular, in the present invention, a plurality of surveillance cameras 1, 2 ... N (1) installed in the guard zone is characterized by directly controlling the voice through the voice control unit 10 of the central control unit. For example, when an outsider's intrusion is detected in the guard zone, change the angle of the surveillance camera for more detailed shooting, or start the operation of the second surveillance camera when it is outside the shooting range of the first surveillance camera. When commanded, the operation of the surveillance camera is controlled through a voice capable of real-time control. As a result, the situation in the guard area can be suppressed more quickly and accurately.

As described above, web cameras equipped with various sensors are installed in homes, general buildings, mountains, military special security areas, coasts, ports, airports, dams, and other areas where security systems need to be constructed. Control and prevent disasters in advance, minimizing human and property damage.

2 is a flowchart illustrating an operation process of a camera tracking system according to an exemplary embodiment of the present invention.

Referring to the drawing, in step 100, the first surveillance camera among the plurality of surveillance cameras installed in the security zone is always monitored in the security zone and transmits the image data and the detection signal in the security zone to the central control unit. . In step 102, it is determined whether an invasion of an outsider occurs in the security zone. As a result of determination, when an outsider invades, the process proceeds to step 104 where the first surveillance camera is used to aim the outside invader, that is, the center of the target. In operation 106, Az and EL of the first surveillance camera are calculated, and when the target is out of the photographing range of the first surveillance camera, the coordinates of the adjacent second surveillance camera are converted in operation 108. In operation 110, the second surveillance camera is moved to the converted coordinates. In operation 112, it is determined whether the second surveillance camera is aiming at the center of the target. If the second surveillance camera does not aim at the center of the target, the process proceeds to step 114 and calculates the deviation and moves to the center of the target. On the other hand, if the determination result in step 112, if the second surveillance camera is aiming at the center of the target proceeds to step 116 proceeds to shoot and track the target invaded in the guard area. At this time, the shooting and tracking of the target invaded in the guard area is performed according to the voice command from the central control unit, this voice command control process is shown in Figure 3 below.

3 is a flowchart illustrating a voice command control process according to an embodiment of the present invention.

Referring to the figure, in step 200, the command is input by the actual voice of the person in charge of the central control unit (central control room), not the command using a conventional mouse or joystick. In this case, the command may be an angle rotation of the surveillance camera in the guard zone or a zoom function operation command. In step 202, the voice of the person in charge of the central control unit is digitally converted, and in step 204, the feature of the voice is extracted. In step 206, the voice that has been previously databased and the voice input in step 200 are compared / searched. In step 208, it is determined whether the standard probability is represented by comparing the similarity between the voice previously databased and the voice input in step 200. FIG. If it is determined that the standard probability is not indicated, the process proceeds to step 210 and requests for voice re-input. On the other hand, when the standard probability is displayed, the process proceeds to step 212 and the voice command issued in step 200 is executed.

The present invention described above is described according to the drawings and limited by way of example, but various changes and modifications are possible to those skilled in the art without departing from the technical spirit of the present invention according to the matter. to be.

As described above, in the present invention, in remotely controlling the operation of the surveillance camera for monitoring the inside of the security zone, the surveillance camera is freely remotely controlled using the voice of a real person. Therefore, it is possible to track and monitor the target more quickly and accurately in case of emergency in the guard area.
