Description

Technical field

The present invention relates to the field of alerting civilians and others about emergencies that pose a threat to their life or health.

State of the art

Emergency warning systems are widely known in the prior art, in the general case they are a complex of a control room and terminal devices capable of receiving an alarm signal from a dispatcher’s console and issuing alarm messages, for example, in the form of voice messages, sirens, etc.

The general disadvantage of such systems is the limited information transmitted, since, for example, the siren signal itself does not contain any information other than audio, and therefore various code schemes for delivering such signals are forced to indicate a specific type of threat (for example, in the form alternating siren beeps). In addition, this type of notification does not provide targeted addressing, as it is usually distributed via unicast broadcasting or sirens located on buildings, towers, etc.

As the closest analogue of the invention, the applicant adopted the warning system disclosed in the patent for utility model RU 128049 U1, 05/10/2013.

In the General case, within the framework of the proposed invention provides for the use of a device for collecting and processing information, which receives information from a variety of sensors located in a particular area, in a particular building, in mines, at test sites and in other places where there is a possibility of emergency situations.

For a more clear understanding of the essence, the presentation of information is made with reference to the corresponding positions in the drawing, which shows an embodiment of a warning system in accordance with the proposed invention.

As sensors (not shown) in the framework of the present invention can be used any known from the prior art controlled means having the ability to generate a signal in response to environmental influences and capable of receiving commands over a communication network. For example, smoke detectors, seismic sensors, temperature and humidity sensors, detectors of the presence of toxic substances in the ground, water and air, etc. can be considered as such means. In some cases, the term "sensor" in the framework of the present invention can be understood as a means of video recording, capable of responding to changes in the environment, for example, equipped with a motion detector.

In accordance with the proposed invention, the device for collecting and processing information (1) polls the sensors, receives a response from them and sends the received information to the signal conditioning unit (3). The specified survey can be carried out once at a predetermined time, and the obtained values can be compared with predetermined limit values. Depending on the configuration of the signal conditioning unit, in order to save traffic, a value of 0 may not be sent.

The signal conditioning unit may be equipped with a controller configured to compare the received data with a predetermined threshold value and, if the threshold is exceeded, generate a code message in the form of a file and transfer the file to the data transmission / reception facility (4). The code message may contain the identifier of the signal conditioning unit (or the identifier of the device for collecting and processing information) and the corresponding values for exceeding the limit parameter (threshold). In this case, the signal conditioning unit converts the code message into a file format of the audio / video file MPEG2 / MPEG4.

A means of receiving / transmitting data using the technology of encapsulating data in the MPEG2 / MPEG4 transport stream encodes the file according to the Reed-Solomon code algorithm and transfers it to the channel-forming means of satellite data transmission / reception (5), preferably operating in the frequency range 5-20 GHz. Further, the means (5) initiates a direct radio connection with the spacecraft (6), preferably located in a geostationary orbit and providing a constant point of standing relative to the surface of the Earth. The device (6) is equipped with a relay system using the frequency range 5-20 GHz. Having received the radio signal, the spacecraft amplifies it and establishes a direct radio channel with another channel-forming means of satellite data reception / transmission (7). Means (5) and (7) may be identical or similar in their functionality and composition to the technical means known to the person skilled in the art.

The tool (7) after receiving the signal restores the received file using the Reed-Solomon code and transfers it to the means of demultiplexing transport streams (universal demultiplexing system) (8) using MPEG2 / MPEG4 technologies. The tool (8) selects the code package and transfers it to the automated workstation of the system operator (9). The workstation (9) may be a hardware-software complex and is also preferably equipped with means for displaying information. From the workstation (9), a request is preferably sent to the object database server (11). In response to this request, the database server of the objects returns to the workstation (9) information containing GLONASS or GPS coordinate of the object that sent the code package (1).

At the operator’s workstation, an event is displayed and a request is issued to the operator to turn on the warning signal. In the absence of an operator, this request can be performed by the system automatically. If necessary, the operator initiates a visual inspection command. In the case of initiating a visual control command, the operator’s automated workstation generates a code package containing the identifier of the information collection and processing device and sends it sequentially through another means of receiving / transmitting data (4 ′), other channel-forming means of satellite data reception / transmission, spacecraft, channel-forming means for satellite reception / transmission of data, means for receiving / transmitting data, a signal conditioning unit to the corresponding code message of the device with boron and information processing.

The device for collecting and processing information compares the identifier from the received code parcel with its own and, if they match, it makes a video recording of the area through the camera.

The resulting video file is sent along the chain of devices (1) - (3) - (4) - (5) - (6) - (7) - (8) to the operator’s workstation (9).

In case of confirmation of an emergency by the operator, the workstation (9) requests from the database server of the objects a list of objects falling into the potential zone of destruction. Having received the relevant information, the workstation (9) generates a command containing the identifiers of the objects and the notification file, which is sent to the means of interfacing with the transceiver devices (12) and / or through the device chain (4 ′) - (7) - (6) - ( 5) - (4) - (3) to the device for transmitting voice information (2). Means (12) send a command to turn on the terminal public warning systems. When sending a command along the device chain (4 ′) - (7) - (b) - (5) - (4) - (3) the voice information transmission device receives the command, analyzes the identifier included in it with its own and, if the identifiers match , turns on the alert.

Moreover, in the embodiment, the means (12) also send a command in the form of a file to the backup channel generation tool (13), which encodes the file according to the Reed-Solomon code algorithm and using data encapsulation technology in the MPEG2 / MPEG4 transport stream, as well as using the technology transmitter control DVB-T2 (T2-MI) and transmits it to the broadcasting center (14). The center (14) multiplexes this stream fragment into the air stream and sends it to the demultiplexing means of the backup channel (3), where the stream is demultiplexed and the command is sent to the voice information transmission device. The device for transmitting voice information using the backup signal receiver DVB-T2 (T2-MI) receives the signal and turns on the warning signal.

The information disclosed above allows a specialist to evaluate all the advantages of the proposed invention, and also provide the possibility of its implementation in industry.

Using the proposed signal relay scheme can significantly increase the coverage area of the emergency warning system. The coverage area of the system is also expanding without the introduction of specialized devices for receiving emergency information, since the digital broadcasting standard adopted in Russia complies with the DVB-T2 standard, which is characterized by high bandwidth and stability of the received signal. It should be borne in mind that television receivers capable of receiving a signal of this standard are widespread not only in the homes of ordinary citizens, but also are installed everywhere in crowded places. The encapsulation of data proposed in the claimed system in a digital broadcast stream allows transmitting not only voice messages, but also any other type of digital information, including video, data and encrypted messages, significantly increasing the information content of notification messages, while this kind of encapsulation can also be applied in other current digital broadcasting standards. High addressing and simple scalability of message delivery is achieved through the use of unique identifiers, while the tools included in the system, through identifiers, provide automatic verification of the need to activate the notification process, taking into account information about the potential zone of damage.
