Description

The invention relates to the field of video surveillance of objects and can be used to quickly obtain video information about the state and / or situation at the monitored objects, such as a crossroads on a transport highway, a section of road, parking, adjacent territory, etc. in real time .

Known Method of multichannel video surveillance, video surveillance of the state of the object, video surveillance is carried out by video cameras, the video signal from each video surveillance unit is introduced into a single cable line, from which the video signal is transmitted to the input of the visualization system (RF Patent No. 2250503, G08B 13/196; 25/08; H04N 7/18, op. 20.04 2005).

The disadvantage of this Method is the use of outdated television cable lines and the high cost and complexity of using several centers for receiving information due to the need to lay highways to each center.

The closest technical solution is the Method of multichannel video surveillance of traffic intersections, which consists in placing video surveillance devices at video surveillance sites, video surveillance of video surveillance objects by means of video surveillance devices and video transmission from the video surveillance devices to the central server, through which the video signal is output as video image of the object on the screen of the user's device via wired or wireless Second line of communication in real time. (Patent of the Russian Federation No. 2442217, G08G 1/04, op. 10.02 2012, the prototype.)

The disadvantage of the known Method is: high load on data transmission channels due to the continuous transmission of information from all objects, regardless of the degree of need at a given time, and the complexity of obtaining information from other objects other than video surveillance cameras, such as video signal repeaters.

The proposed solution eliminates the above disadvantages and improves the efficiency of video surveillance of video surveillance objects, including by reducing the load on communication channels and server capacity, thereby ensuring long-term stable work on video surveillance of video surveillance objects, transmitting the video image of the video surveillance object in real time from video surveillance devices to one or at the same time several user devices through a central server with a computer lexom programs and receiving live video information about the state and / or situation on the monitored video surveillance object at a given point in time and for a specified time, which in turn allows you to quickly respond and manage the video surveillance object, as well as ensuring security at the video surveillance object.

This goal is achieved by the method of video surveillance of objects, which consists in placing video surveillance devices on video surveillance objects, video surveillance of video surveillance objects by means of video surveillance devices and transmitting video information from video surveillance devices to a central server, through which video output is performed as video image of the object on the screen of the user's device via a wired or wireless communication line in real A pre-developed map of a given area, on which video surveillance devices are placed at video surveillance sites with a geo-coordinate reference to a given area, then the developed map of a specified area is entered into the central server software as a site map of a specified area; registration in a central server with software for obtaining an access code to the site of a map of a given area, according to the results of registration The user’s device receives an access code as a combination of data, the access code is entered into the access code database of the central server, after which the registered user device queries the central server to provide access to the site map of a specified area, upon request from the user's device, the central server software checks the combination of access code data by matching the entered access code data combination with the registered Nation of the access code data and, if they coincide, the central server provides access for the user's device to the site map of a given area, select at least one video surveillance object and video surveillance of the selected video surveillance object for a specified time using the video signal transmitted at a given moment time from a given device or video surveillance devices, while the video surveillance of the video surveillance object is carried out from one or several user devices are additionally placed on the map of a given area traffic lights and carry out a change in the mode of operation of the traffic light on a given video surveillance object in real time.

FIG. 1 shows a diagram of the implementation of a video surveillance method for video surveillance objects, on which video surveillance is performed from one user device on a video surveillance object from the first video surveillance device and simultaneously from two other user devices on another video surveillance object from a second video surveillance device, FIG. 2 shows a diagram of the implementation of the method of video surveillance of video surveillance objects, on which video surveillance is carried out simultaneously from three user devices behind one video surveillance object from the first video surveillance device, while the second video surveillance device does not transmit information.

The method of video surveillance of objects is as follows.

Carry out the placement of video surveillance devices 1 (hereinafter referred to as "Devices") on the objects of video surveillance. Objects are, for example, a crossroads, a section of a road, a parking lot, a territory adjacent to a building, a parking lot, etc.

At the same time, a map of a given area is preliminarily developed and devices 1 are placed on video surveillance sites on a map of a given area. Devices 1 are placed on a map of a given area with a geo-coordinate reference to a given area, which contributes, among other things, to a visual representation of the entire network of video surveillance objects (hereinafter referred to as “Objects”) and, accordingly, increases the effectiveness of video surveillance.

Then the developed map of a given area is introduced into the software of the central server with a complex of programs 2 as a site of a map of a given area.

Device 1 is configured to transmit video information from an object to a central server 2 via a wired or wireless communication line in real time, for example, from a road junction with traffic flows, and is a network device that has a fixed IP address that can transmit, for example, video signal - a video stream using the RTSP protocol, accessible at a given address, and represents, for example, a video camera, an IP camera and / or a relay server.

At least one device 1 transmits video information from an object to a central server with a set of programs 2, which displays the video signal as a video image of an object on the screen of at least one user device 3 via a wired or wireless communication line in real time.

The central server with software package 2 is, for example, a computer with Web server capabilities; a relay server that transmits multiple streams of information, such as transport streams, simultaneously.

Also, the central server with the software package 2 is a two or one computer with the specified software that allows you to receive and transmit video in the form of a video image of an object in real time, for example, one computer with the specified software 2 allows you to receive the video signal in the form of a video image, at least measure one object in real time simultaneously for multiple user devices 3.

The site of a map of a given area is, for example, a map of the area of a city on which objects with geographically-coordinate reference to a given area are placed.

The user's device 3 is made with the specified software that allows access to the Internet, and is a device in the form of, for example, a computer, a web browser that supports javascript, HTML5, CSS.

The device of the user 3 at the first access to the central server with the software 2 performs the registration for obtaining the access code to the site of the map of the specified terrain as a combination of data. As a result of the registration, the user's device 3 receives an access code in the form of a combination of data, which is entered into the access code database of the central server 2. Then the user's device 3, equipped with a personal access code on the site map of a specified area and registered in the access code database of the central server 2 , carries out a request (authorization) to the central server 2 to provide access to the site maps of a given area. The central server 2, upon request from the user device 3, verifies the access code data combination by matching the entered data of the access code data with the registered data combination of the access code and, if they match, the central server 2 provides access for the user device 3 to the site of the specified terrain map.

The data of the access codes of the user devices 3, the data of the requests of the devices of the user 3 and the data about the video surveillance objects are stored in the databases of the central server 2. The server part of the central server 2 provides the mechanisms for the authorization of the user 3 devices, provides for separation of access rights and displaying video information about the video surveillance objects. The central server 2, when authorizing a user device 3, accesses the database of access codes in order to obtain information about the user devices 3 registered in it.

For example, after successful authorization, i.e. User device 3 is registered in the access code database, central server 2 accesses the database of video surveillance objects, receives video information about at least one object and sends the received video information about a given object to the screen of user device 3 that made the request to the central server 2 with a set of programs.

Thus, after the user's device 3 has accessed the site of a predetermined terrain map from this user device 3, at least one object is selected, and then the selected object is monitored for a specified time and in real time.

Video surveillance of the selected object is carried out by means of the device or devices 1 and video surveillance of the video signal transmitted at a given moment in time from a given device or devices 1 through the channels of a wired or wireless communication line to the central server 2, which carried out the video signal output to the screen, at least one user device 3 via wired and / or wireless communication lines.

In this case, video surveillance of the video surveillance object is carried out from one or simultaneously from several devices of user 3.

Channels 4 wired lines are a twisted pair UTP / fiber, wireless channels are GPRS / 3G / 4G or Wi-Fi.

The user's device 3, which has access to the video information of the object, receives video information about the object not permanently, but at a given time, for a specified time and in real time, which contributes, among other things, to a significant reduction in the load on communication channels and server capacities.

For example, the transmission of video information in the form of a video image of an object from device 1 is transmitted via wired and / or wireless communication lines in real time, at a given point in time and for a specified period of time to a central server with software 2, which then outputs this video signal as video image of the object on the screens simultaneously to three devices of the user 3 via wired and / or wireless communication lines. Thus, video surveillance of one object from one device 1 is carried out simultaneously from three devices of user 3.

Video information about an object from device 1 is, for example, video information about the actual location of an object with geo-coordinate reference to a specified location (object coordinates); video information about the state of the object; video information about the situation at the facility, including fire, emergency, traffic jams; traffic and / or pedestrian traffic information; about the technical characteristics of the device 1, etc.

The web interface of the video surveillance system for objects allows you to view this map and, if necessary, modify it, for example, add or delete objects, as well as receive additional information about devices 1, for example, on the site maps of a given area. , when you click on an object icon on a map of a given area, an additional window opens with additional information, for example, a description of device 1 (information about models and characteristics of video surveillance devices), addr eu object, traffic video, etc.

Video surveillance object carry out:

at a given time, for example, at any time of the day; in the morning and evening; in the morning time; in the evening, etc .;

within a specified time, for example, within a month; in a week; during the day, etc .;

at a given time and within a specified time, for example, during the month at any time of the day; during the week at any time of the day; during the day at any time of the day; during the month in the morning and evening; during the week in the morning; during the day at any time, etc.

The user's device 3 analyzes the received video information about the object and, based on the results of the analysis, decides whether or not to make a change on the object:

for example, a traffic congestion has formed on the road section and it is decided to make a change on the object from the user's device 3: eliminate the traffic congestion on the object by changing the movement of vehicles, thereby controlling the situation on the object.

Additionally, on the map of a given area, traffic lights 5 are placed on objects and in addition, the operation mode of traffic light 5 on a given object is changed directly from device 1 in real time:

for example, for pedestrians, a push-button system is installed or automatic; install an additional arrow by installing additional modules; changing the duration of the traffic light signals, thereby reducing, for example, the workload of a particular section of the road and getting rid of the traffic jam; changing the direction of traffic and / or pedestrian traffic; the change at the intersection of two highways modes, namely, a red signal stops the movement of all vehicles at the intersection, and at this time a green signal permits the movement of pedestrians at the intersection.

In this case, the video information is, including information, for example, information about the modes of operation of traffic lights.

That is, from the user's device 3, if necessary, manage the object, for example, change the mode of operation of a traffic light at a particular intersection and accordingly change the settings of the traffic flow, the flow of pedestrians by changing the intensity of traffic flow on a given object; eliminate an emergency situation by removing a traffic jam at a crossroads or highways; provide unimpeded movement of buses on line A; fill the parking area; call an ambulance to the object in case of an accident in the parking lot; call an emergency crew to the site; cause snow removal equipment to the object for cleaning the snow blockage on the territory adjacent to the road; call the police to the site; call the road service at the facility; cause fire service at the facility; etc.

As soon as the user’s device 3 or user’s device 3 finishes viewing the video information - the video stream from the object, the central server 2 closes the connection with the device or devices 1 and the video information about the object is closed.

An example of a specific implementation.

Pre-develop a map of the Leninsky district of the city of Tyumen. What for on the map of the Leninsky district of the city of Tyumen, namely, at the facilities of the Leninsky district of the city of Tyumen, devices 1, which are video cameras, are placed, while devices 1 are placed geographically - coordinate referencing to a given area.

The object is a crossroads of the Republic and Ordzhonikidze streets.

Then, the developed map of the Leninsky district of the city of Tyumen with the facilities of the Leninsky district of the city of Tyumen and the devices 1 placed on them is entered as a site map of the Leninsky district of the city of Tyumen into the software of the central server 2, which is a computer with Web server capabilities and having the ability to transfer several transport threads at the same time.

Three devices of user 3, which are computers, register in the software on Central Server 2 and receive an access code to the site with a map of the Leninsky district of the city of Tyumen based on the results of registration. The access code to the site map of the Leninsky district of the city of Tyumen is a combination of numbers and letters.

Each registered computer 3 makes a request by entering its access code into the software of the Central Server 2, which checks the entered data of each access code of computer 3, matching the entered combination of numbers and letters with the registered combination of data of the access code in the database of the access code of user devices.

If the access code coincides, the central server software 2 accesses each computer 3 to the site of the map of the Leninsky district of the city of Tyumen.

From each computer 3, a given object is selected on the map of the Leninsky district of the city of Tyumen: the intersection of Respublika and Ordzhonikidze streets and video surveillance of the selected object, namely, the intersection of Respublika Respublika and Ordzhonikidze, from three computers 3 simultaneously during the week in the morning and evening real time.

Video surveillance of the crossroads of Republic and Ordzhonikidze streets is carried out from video camera 1, located at the crossroads of Republic and Ordzhonikidze streets, which sends video information from the crossroads of Republic and Ordzhonikidze streets via Wi-Fi to the central server 2, which transmits the received video information, by outputting the video signal as a video image of the intersection of Republic Street and Ordzhonikidze simultaneously on the screens of three computers 3 via wireless channels 4 th communication in the form of Wi-Fi.

Video transmission in the form of a video image of the intersection of the Republic and Ordzhonikidze streets from the video camera 1, located at the intersection of the Republic and Ordzhonikidze streets, is carried out in real time during the week in the morning and evening.

In the process of video surveillance from three computers, 3 monitor the condition and traffic situation at the intersection of Republic and Ordzhonikidze streets: for traffic and pedestrian traffic jams.

Analyze the video information obtained from the video camera 1, located at the crossroads of the Republic and Ordzhonikidze, and conclude that a non-standard situation has arisen in the form of a traffic jam at the crossroads of the Republic and Ordzhonikidze in the evening.

Then decide on its elimination.

Since the traffic jam arose due to the snow that was not cleaned on time on the road, which interfered with the heavy traffic flow in the evening, road equipment was used to remove snow from the roadway.

The snow was removed, the traffic flow was restored in the working mode.

Video surveillance of this object is finished.

The proposed solution allows to increase the efficiency of video surveillance of video surveillance objects, including by reducing the load on communication channels and server capacity, thereby ensuring long-term stable work on video surveillance of video surveillance objects, transmitting the video image of a video surveillance object in real time from a video surveillance device to one or simultaneously several user devices through a central server with a complex of programs and receiving opera ivnuyu video information on the status and / or the situation on the monitored video object at a given time and for a predetermined time, which in turn makes it possible to react quickly and manage the object surveillance, as well as simultaneously providing security at the facility surveillance.

Reducing the load on the video data transmission channels, at the same time, the complexity of obtaining video information from other objects other than video surveillance cameras, such as video signal repeaters, from using multiple information receiving centers due to the need for laying highways to each center, also reduces costs.
