4 is a flowchart illustrating a flow of transmitting an acquired image to a receiver.
The present invention relates to a mobile security system, and more particularly, a security system capable of transmitting image information of a site to a user through an HSDPA mobile communication network and providing information on the field image to an emergency personnel on site by voice. It relates to a control method of the system.
In general, a security system is a general term for facilities and equipment for protecting people and property from various disasters, accidents and crimes. Types of security systems include unmanned security systems of facilities, home security systems, unmanned security systems of financial institutions, closed circuit television (CCTV), product theft prevention systems, and access control systems.
The unmanned security system of the facility is a system that detects the occurrence of an accident such as an outsider's unauthorized intrusion and sends a signal to the security service provider's situation room and sends the incident handling personnel of the security service provider to the accident occurrence facility. It is used in various facilities such as schools, department stores, shopping centers, supermarkets, private houses, offices and buildings. The home security system detects accidents such as unauthorized intrusion, theft, gas leak, fire, etc. and sends the detected signal to the wired / wireless transmitter in advance to notify the danger and the owner of the home who receives the signal returns home or provides security services. It is a system for emergency dispatch of accident handling personnel at home. The unmanned security system of financial institutions is a system that can automatically operate lighting control, announcements, various error detection, and opening and closing of doors in computers in open areas such as 365 corners of financial institutions such as banks. It is possible to remote control. CCTV system is a system that prevents an accident and tracks the situation of an accident when it occurs by monitoring and recording the behavior of the person in a situation that cannot be controlled by general security equipment such as a large workplace with a lot of outsiders.
Such conventional security systems primarily detect intruders using infrared sensors or heat sensors. However, these sensors detect infrared rays or body temperature included in the thermal element of the object. Therefore, when an intruder uses clothing or other tools that block radiant heat emitted from the human body, the intruder may not be detected. Also, the intruder may not be able to detect the intruder. It may cause malfunction. In addition, most conventional security systems are configured to notify the situation room by a wired line such as a dedicated line, a telephone line, and the like. Therefore, when an outsider cuts the wired network, enters the facility, or cuts the wired network due to a fire, the emergency cannot be grasped. In addition, since the conventional security systems must have a lot of additional equipment, there is a problem that the maintenance and management by a private security company is relatively expensive. Recently, a system for transmitting a sensed voice signal to a mobile phone by using a telephone line has emerged. Such a system may reduce the administrative cost of a private security company, but relies on an infrared sensor to detect intruders only. The problem of being vulnerable to disconnection by using dot and wired networks remains a problem.
The present invention has been made to solve the conventional problems as described above, in judging the intruder, in addition to the heat detection by the infrared ray or motion detection sensor in addition to rotating the line laser to project the intrusion by the refraction or distortion of the laser, etc. In addition to detecting, by combining and correcting and analyzing the image information obtained from the omni-directional camera, it is possible to determine the external intrusion more accurately, and to provide the user with real-time information on the site situation through the HSDPA mobile communication network It is a first and second object of the present invention to provide a security system and a method for controlling the security system.
In addition, the user can remotely control the peripheral device of the on-site security system at a long distance using the HSDPA mobile communication network, and in case of external infringement, the user can directly watch the video from the remote site and transmit the situation to the police by voice to enable effective facility security. A third object is to provide a security system.
In addition, a fourth object of the present invention is to provide a security system that can more accurately identify an emergency situation such as a gas leak or a fire, and notify a user located at a remote location.
The present invention for achieving the above object is provided with a camera capable of 360-degree omnidirectional shooting, in the security system for transmitting a video signal obtained from the surveillance camera to the designated path through the HSDPA mobile communication network, 360-degree for surveillance A processor unit for correcting and converting an analog image signal input from a camera into digital image data; A laser rotation driver and encoder which rotates 360 degrees and projects a line laser and detects refraction or distortion of the laser; A flash for acquiring an accurate image in a dark place; An illumination sensor which senses brightness around the security system and operates a built-in flash; An acceleration sensor unit detecting a movement of the security system; And a wireless module for transmitting the image data corrected by the processor through the HSDPA mobile communication network and receiving the control data received through the mobile communication network.
In addition, the present invention comprises a camera capable of 360-degree omni-directional photographing, and in the security system control method for transmitting a video signal obtained from the surveillance camera to the designated path through the HSDPA mobile communication network, input from the surveillance 360-degree omnidirectional camera Correcting and converting the analog video signal into digital video data; Periodically rotating 360 degrees to project a line laser, generating intruder detection information through refraction or distortion of the laser, and determining whether to intrude; Sensing the brightness around the security system to activate the embedded flash; And transmitting the image data corrected by the processor through the HSDPA mobile communication network. And a user receiving a danger signal and controlling the security system through the HSDPA mobile communication network.
Hereinafter, with reference to the accompanying drawings for a mobile security system by a omnidirectional sensor according to the present invention will be described a preferred embodiment.
According to Figure 1, a preferred embodiment of the security system according to the present invention is to identify the contrast around the camera (capable of 360-degree omni-directional shooting), the laser rotation drive for rotating and projecting the line laser, the laser rotation encoder, the security system It consists of an illuminance sensor, a flash to correct the brightness, an acceleration sensor to detect movement of the system, a wireless module to transmit danger signals and field images to the user, and to receive control signals. It may include a motion sensor and a PIR sensor.
The camera transmits circular image information obtained by capturing 360 degrees at a time to the processor, and the processor includes a digital image converter (not shown) capable of correcting the received image signal in a planar form.
The laser rotation driver rotates the line laser by 60 degrees and projects it diagonally, and the laser rotation encoder detects whether the projected laser is refracted or distorted.
The illuminance sensor recognizes the brightness of the surrounding area to obtain accurate image information, and if the illuminance is too low to obtain clear images, the illuminance sensor drives the flash installed in the system to increase the illuminance. Detect that the system is being moved by an intruder. The wireless module transmits the acquired video data of the processor to the user's mobile communication device through the HSDPA mobile communication network when the system detects an intruder or moves the system in an illegal manner by the acceleration sensor, or from the user through the HSDPA mobile communication network.

It has the advantage that it can secure the constant of security status. On the other hand, the image information obtained from the camera provides a clear information about the scene situation gives the user a strong confidence in determining whether an emergency situation caused by external intrusion. However, in the case of confirming whether the intruder is only based on the image information obtained by the camera, inaccurate images may be transmitted due to differences in the surrounding brightness and the like, thereby reducing the reliability of the image information. Therefore, the illuminance sensor may determine whether it is possible to acquire an accurate image and operate the mounted flash.

However, if there is an intruder in the field and the refraction or distortion of the projected line laser is detected, the image information of the corresponding area is stored and the encoder value of the corresponding area is checked to obtain a 360-degree omni-directional screen when an abnormality occurs.
4 is a diagram illustrating a process of driving a mobile security system and transmitting an image by an omnidirectional sensor camera.
When the security system operates, it checks the timing of 360-degree image captured by the line laser projection error, and the acceleration sensor determines the movement of the security system, and then detects the darkness around the system through the illuminance sensor. By determining whether the operation is to obtain a visible light image of the omnidirectional identifiable. The 360-degree omnidirectional circular image thus obtained is converted into a planar image by the processor and transmitted to the user's mobile phone using a bus module.
On the other hand, the processor that occupies the center of the system controls the operation of the system by comparing the sensor values detected by the various sensors in addition to the correction of the image, and transmits the image obtained through the wireless module, the user uses Receives a control signal transmitted through a wireless module to control the driving of various devices (rotation, flash operation, image zoom in / out) of the system.
