Description

The invention relates to the field of burglar alarm and can be used to scan the current situation in the premises.

A known system (RF patent No. 128755, G08B 19/00, 05/27/2013) of fire monitoring, including hardware for receiving and transmitting information located at facilities that are connected via GSM, SMS or GPRS communication channels to the information collection and processing unit . The unit for collecting and processing information via Internet communication channels is connected with the fire department and at least one analytical unit, which is a hardware and software device that includes a computer with software that contains a database of state parameters of objects with the possibility of its constant replenishment and editing .

The disadvantage of the system is that the sensors are connected to the data collection unit via the cellular network, that is, they depend on the coverage area of the mobile operator, when used in non-remote premises there will be increased costs for communication services. Also, there is no possibility of independent movement of the sensors, since they are connected to a device for collecting and transmitting via a wired data channel.

Known intelligent security camera and tracking system for the image with an intelligent camera (RF application No. 20111137821/07, H04N 7/18, 07/10/2013). A security camera for obtaining a monitored image that must be displayed on a remote control device, and for controlling a centralized monitored image acquisition unit without using a remote control device.

The disadvantage of the system is the inability to move the camera, the inability to transfer surveillance of the object to another camera when the first one fails without a command from the control point.

The closest in technical essence and the achieved result to the claimed one is a video surveillance system (RF patent No. 127500, G08B 13/00, 2013), containing a computer connected to it by communication channels, a controller, to which, in turn, is connected by at least at least one video camera and safety sensors connected to the controller, such as motion sensors. Schemes of the protected object in 3D format are entered into the computer memory. Camcorders can be rotatable. At least one microphone may be connected to the computer. A modem connected to the Internet can be connected to the computer. The video surveillance system may include a webcam connected to a computer. A computer can be connected through an uninterruptible power supply to an electrical network and, at the same time, through a switch to an independent energy source.

The disadvantage of the analogue is the incomplete control of the object, since the cameras are located at a specific point and can only change the viewing angle. In the event of a dynamic obstacle to viewing the video camera, the state of the object is not fully monitored.

The objective of the invention is a reliable, fast and efficient data acquisition from the scanned area.

Effect: scanning a large area of premises, improving the reliability and quality of the process of collecting video information, increasing the fault tolerance of the system due to the possibility of moving video sensors.

The problem is solved and the technical result is achieved by using a video surveillance system containing a computer connected to a control unit to which a group of video sensors are connected. The system is characterized in that it contains video sensors that can be moved along the guides in such a way that when there is a lack of video information about the state of the protected object, the video sensors change their position on the guides in order to ensure the required quality of collecting information about the state parameters of the protected object.

The problem is solved and the technical result is achieved by the method of video surveillance, in accordance with which the video sensors are moved along the guides installed on the plane, accompany the video object, scan the state of the video object, obtain a panoramic and three-dimensional image using software installed on a personal computer, while failure of one video sensor, its task is transferred to another. Moreover, communication with video sensors is carried out over the air.

The invention is illustrated by drawings. In FIG. 1 - structure of a video surveillance system. In FIG. 2 - internal structure of the video sensor. In FIG. 3 and 4 show a model of a room with several video sensors; FIG. 5 - PC with a video sensors control unit connected to it.

In FIG. 3 shows a reduced model of a room with four video sensors. In real conditions, the room area can be much larger. Video sensors move along the guides when a signal arrives. If there is a lack of information or if the video sensor fails, it is supplemented or replaced by another. The control unit allows you to receive data from video sensors over the air. And it connects to a personal computer using a USB cable.

A multi-agent self-organizing video surveillance system contains a personal computer (PC) 1, a control unit (BU) 2, and a plurality of video sensors (VD) 3.

The video sensor 3 consists of a video camera 4 connected to a microprocessor 5 to which a radio module 6 is connected. All logical actions of the video camera and the radio module are carried out by the microprocessor. The video sensor, if necessary, can be supplemented with motion sensors 7, smoke 8, temperature 9, gas, pressure, etc. (Fig. 2). If the settings are exceeded, the initiative to start data exchange will come from the video sensor. It is also possible to connect actuators, in case you need to perform a certain action, for example, in case of fire.

Multi-agent self-organizing video surveillance system works as follows. A control unit 2 is connected to PC 1, which receives data from the computer via USB and transmits it over the air (RC) to the corresponding video sensor 3 (Fig. 1). The control unit 2 is powered by an independent power supply unit or from a USB connector. Video sensors are non-volatile. Video sensors can be powered from the battery or from the battery. When the battery level decreases, the video sensor, moving along the guide, can independently connect to the power terminal and charge the battery (not shown in the drawing). Each video sensor 3 has a non-volatile memory for duplication for a certain time of the information that he collected. The collected information is stored in the database on PC 1. At the request of the user, a certain area is scanned by video sensors and video information is transmitted to PC 1. The received images are processed and the user sees processed, glued images or an image in 3D format. With many tasks, the system itself makes decisions on the allocation of resources according to the priority and optimality of the resources expended.

Concrete implementation example

1. If there is a suspicion of an emergency in the form of a fire, the video sensor 3 responds to smoke and sends a signal to the control unit 2. Next, the signal is processed on PC 1 using the installed software and video sensors 3 send a command to collect video information through the control unit. In the process of collecting video sensors distribute tasks among themselves and move along the guides, since there may be several tasks and there may be obstacles to receiving video information. The video information collected by the video sensors is transmitted to a PC. Further, the video sensors receive a new signal to collect information or continue to further collect video information on the previous task.

2. In the case of tracking an object and when it is required to collect as much video information about the object as possible, using a human example, the PC transfers the task through the control unit to the video sensors. Video sensors begin collecting video information. When a person moves, video sensors can accompany him or transfer a task to a nearby video sensor. If a three-dimensional image of a person or a panoramic image of a room is required, then video information is collected by several video sensors from different points of observation. The collected information is transmitted to a PC, where the information is processed. The user on the PC monitor sees the exact location of the person, the current situation in the room on a panoramic image and can look at the volumetric image from different angles at the object of observation.

So, the claimed invention allows:

- Reliably, quickly and efficiently receive data from the scanned area;

- scan rooms of a large area;

- improve the reliability and quality of the process of collecting video information;

- increase the fault tolerance of the system.
