Description

The present invention relates to the field of railway technology and can be used to monitor and alert performers when working in a hazardous area.

The main source of information on the possible impact of hazardous production factors for workers performing work related to entering railway tracks (i.e. in the so-called hazardous zone) is radio communications carried out both with the dispatching personnel (for example, at the station , with the station attendant), and with other workers on the tracks, for example, a signalman (or an employee who fenced off work sites and secured rolling stock on railway transport).

The lack of individual information via radio communication is that the dispatching personnel do not always know the exact location of each worker on the tracks or do not always have complete information about all hazardous production factors.

A known system for alerting workers on railway tracks during the production of repair and track works, comprising a transmitting device and annunciators; the transmitting device is a walkie-talkie located at the signalmen, transmitting a signal to sirens, which are bracelets that are in all workers involved in repair and track work, receiving a signal in the form of vibration and light warning, while the bracelets are additionally equipped with a feedback button, when when pressed, a signal is transmitted to the manager's control panel, which in turn is designed to receive a signal from a transmitting device about the approach of a mobile train, monitor the health of the system and receive alarm signals from bracelets about an urgent need to suspend work (RU 2701267 C1, B61L 23/06, 09/25/2019).

The well-known system for alerting workers on railway tracks requires the mandatory presence of a signalman that detects the presence of a hazardous production factor (moving rolling stock).

In addition, the use of bracelets may not be applicable to a number of workers interacting with the rolling stock, for example, train builders traveling on the running boards of rolling stock, for safety reasons, as it can lead to injury.

The closest analogue to the claimed invention is a complex for video surveillance and determination of the location, physical condition of a person, including a monitoring and video surveillance center, N wearable terminal devices, including a video camera with a wireless interface module combined with a wireless interface, located on a person, connected with a monitoring and video surveillance center , with the presence in the terminal device of a navigation receiver of signals from satellite navigation systems GLONASS, GPS, Gallileo, a compass with a wireless interface module, an audio headset with a wireless interface module; graphic information display devices with a capacitive screen and a wireless interface module, two heart rate sensors with a wireless interface module, a transceiver with a transceiver for transmitting video information, a transceiver for transmitting / receiving audio information and data; a microcontroller for controlling and compressing video information with a wireless interface module, a GSM modem, an information encryption module and an RFID tag detection module; the presence in the monitoring and video surveillance center of N transceivers for receiving video information (by the number of wearable terminal devices), a transceiver for transmitting / receiving audio information and data, a GSM modem connected via an encryption module to the operator's personal computer; at the same time, the wearable terminal device and the monitoring and video surveillance center include encryption modules that protect the transmitted information (RU 2013149592 A, G08B 21/02, 05/20/2015).

The disadvantage of the known complex is the lack of the possibility of real-time detection of hazardous production factors on railway tracks and predicting their occurrence with the subsequent notification of the work performers in the automatic mode.

The technical result consists in increasing the efficiency of control and notification when carrying out work in hazardous areas by automating the process of monitoring and alerting performers, as well as by predicting the onset of hazardous production factors in control areas.

In addition, the post 1 of control and notification includes an interface unit 24, with inputs / outputs connected to other outputs / inputs of the central processor 11, and a wearable device - mounted on the outer side of the case and connected to other outputs / inputs of the microprocessor 12 connector 25 for connection to the unit 24 pairings of 1 control and notification station.

In another embodiment (see Fig. 2), the monitoring and warning system during work in a hazardous area additionally contains a transceiver 27 installed on a controlled rolling stock 26 with a safety device on a relay element base, configured to interact via a radio channel with the transceiver 7 of the control post 1 and notifications, an indication unit 28, a sound alarm unit 29 and a navigation signal receiver 30, the output connected to the input of the transceiver 27, the output of which is connected to the inputs of the display unit 28 and the audio alarm unit 29, while the indication unit 28 and the audio alarm unit 29 are installed in driver's cab.

In the third embodiment (see Fig. 3), the monitoring and warning system during work in a hazardous area additionally contains a transceiver 32 installed on a controlled rolling stock 31 with a safety device, on a microprocessor element base, connected to a safety device 33, while a transceiver 32 made with the ability to interact over a radio channel with the transceiver 7 of the post 1 of control and notification.

The monitoring and warning system during work in a hazardous area (see Fig. 1) operates as follows.

Video cameras 3 are installed in such a way as to ensure coverage of the entire control area of a section of a railway line, station or other industrial premises. Each video camera 3 is connected to the processing unit 4 of the control and notification post 1 via a communication line. The communication line, depending on local conditions, can be performed wirelessly using Wi-Fi technology or wired using Ethernet technology, or in the form of their modifications.

Video cameras 3 in real time capture the video image of the monitoring area and send them to the processing unit 4.

The processing unit 4 is a microprocessor device. When the position of objects, people, etc. appears or changes. in video frames received from video cameras 3, processing unit 4 based on algorithms built with the use of artificial intelligence determines: the type of hazardous production factor (moving rolling stock, oversized space, broken overhead wire, spill of dangerous goods, etc.) , location and boundaries of the zone of influence of a hazardous production factor. In addition, block 4, based on the processing results, predicts the possibility of a hazardous production factor, for example, it identifies wagons with dangerous goods that can cause a hazardous production factor associated with the properties of a chemical effect on the human body, and determines their location, monitors changes in their state. etc. The block 4 sends the processing results to the central processor 11.

Block 6 of the digital map of control zones is made in the form of a memory device containing information about control zones in coordinate form, including information about track infrastructure facilities, information about hazardous production factors known from regulatory documents at the time of designing the system (location of oversized places, etc.).

The central processor 11 analyzes the results of processing the video image of the control zones and transmits to block 6 information about the types of newly identified hazardous production factors and their location and boundaries in the control zones for recording on a digital map. In this case, information about the newly identified hazardous production factors and their boundaries in the control zones is displayed on the monitor of the display unit 9.

Before starting work in the hazardous area, the operator of the control and notification post 1, using the data input unit 10, registers the identification number of the wearable device 2 for a specific performer of work and enters this data into the central processor 11. Data on assigning the wearable device 2 to a specific performer central processor 11 directs to block 8 of memory.

The issuance of the wearable device 2 to the performer assigned to it and the control that the employee has placed the device 2 on the uniform on the chest is carried out before the start of the shift, for example, at a safety briefing or a planning meeting. The handover of the wearable device 2 by the employee is carried out after the shift.

When carrying out work in the control zones, the power supply unit of the wearable device 2 is in the switched on state. The receiver 17 of navigation signals interacts with the satellite navigation system GPS / GLONASS and determines the location of the wearable device 2, and, consequently, the location of the work performer. The coordinates of the location are sent by the receiver 17 of the navigation signals to the microprocessor 12.

In addition, the video camera 21 takes pictures of the work site in real time, and the microphone 22 registers sounds at the work site.

The video camera 21 and the microphone 22 transmit data on the results of the video recording and the sound background of the work site to the microprocessor 12, which sends them to the memory unit 14.

The memory unit 14 is a non-volatile memory such as a flesh drive. The accumulation of such a significant amount of information in the memory unit 14 of the wearable device 2 makes it possible not to load the wireless communication line.

In addition, the memory unit 14 may contain a recording for subsequent playback in order to assist an employee equipped with a wearable device 2. The sequence and order of work is recorded in the memory unit 14 before the start of a work shift. The wearable device 2 is connected through the connector 25 to the interface unit 24. The duty dispatching personnel or the responsible operator, through unit 10, enters data on the sequence and order of work into the central processor 11, which sends them to the memory unit 8, and through the interface unit 24 and connector 25 transmits to the microprocessor 12 for writing to the memory unit 14 of the wearable device 2.

The microprocessor 12, according to the receiver 17 of the navigation signals, generates a corresponding message and through the transceiver 13 transmits by radio to the transceiver 7 of the control and alert station 1, which sends it to the central processor 11. Each message also includes the identification number of the wearable device 2, which allows identifying the work performer.

Wearable device 2 location coordinates may not be accurate enough. This is especially pronounced when large metal structures, cars are in the immediate vicinity, as well as in the intercar and undercar spaces, inside buildings and structures.

Based on the data on the location of the wearable device 2, the central processor 11 requests the data of the digital map of the unit 6, determines the control area in which the performer is located, and determines the video cameras 3 in the field of view of which he can be. According to the results of processing by block 4 of the images of these video cameras 3, the central processor 11 clarifies the coordinates of the location of the work performer and transmits them to block 6 for registration on a digital map.

In this case, the monitor of the display unit 9 displays: in real time, a schematic plan of the controlled area with the location of the work performers equipped with wearable devices 2, the boundaries of known and identified hazardous production factors. This allows the dispatching personnel or the responsible operator to observe the current situation in the control area. If necessary, the dispatching personnel or the responsible operator using unit 9 can request from the central processor 11 the image data of a specific video camera 3 with a decoding of the hazardous production factor for transferring them to the display unit 9.

In addition, the dispatching personnel or the responsible operator using the data input unit 10 can request video and sound at the current time from a specific wearable device 2. In this case, the central processor 11 generates a corresponding address message, transmits it to the input of the transceiver 7, which sends it via the radio channel to the transceiver 13 of a specific wearable device 2 for transmission to the microprocessor 12, which generates an appropriate message, including data on the shooting results and the sound background of the work site of the work performer, received at a given time from the video camera 21 and the microphone 22.

The generated message is transmitted by the microprocessor 12 through the transceiver 13 via the radio channel to the transceiver 7 of the control and notification station 1 for sending to the central processor 11, which transmits them to the display unit 9. In this case, on the monitor of the display unit 9, a video image of the work site is displayed in real time, as well as the sound background of the work site. This makes it possible to ensure control over the actions performed by a specific contractor, ensure control over the implementation of safety regulations, the correctness of individual operations, and prompt feedback from the contractor with a wearable device 2 located on the railway tracks.

The central processor 11 automatically records data on the current state of the schematic plan of controlled areas from block 6; processing results from processing unit 4; requests of the dispatching personnel or the responsible operator from the unit 10, information on the exchange of data from the control and notification post 1 with wearable devices 2 to the memory unit 8, which is a non-volatile memory made in the form of a hard disk, SSD-drive, etc.

At the request of the dispatching personnel or the responsible operator using unit 10, the display of the archive data stored in the memory unit 8 is available on the monitor of the display unit 9, which makes it possible to investigate various incidents related to violation of safety rules, work schedule, negotiation schedule, etc. .P.

The central processor 11 compares the corrected coordinate of the location of the work performer with the wearable device 2 with the coordinates of hazardous production factors. When the contractor is in the immediate vicinity of the zone of exposure to a hazardous production factor or within this zone, the central processor 11 automatically generates a corresponding hazard message and transmits it through the transceiver 7, the radio channel and the transceiver 13 to the microprocessor 12 of the wearable device 2.

Microprocessor 12, having received a danger message, transmits a corresponding signal to blocks 19 and 20 to turn on the light indication and / or sound alarm, notifying the work performer of the presence of danger, and to block 15 - a message to form a voice message to alert about the danger, reproduced by the speaker 23.

In addition, the microprocessor 12 displays the text version of the message for warning about the danger on the display panel of the unit 19. The fact of the receipt of the signal about the danger is transferred by the microprocessor 12 to the memory unit 14. Thus, the performer of work automatically in real time receives information about the nature of the hazardous production factor, i.e. without the involvement of the dispatching personnel or the responsible operator. This helps to reduce the possible consequences of exposure to a hazardous production factor.

In this case, the central processor 11 transmits information about the danger to the alarm unit 5 to attract the attention of the dispatching personnel or the responsible operator to the situation, and on the monitor of the display unit 9 displays the video image from the video cameras 3 of the control zone in which the performer is located, and video images from camcorders 21 wearable device 2.

If the state of health of the work performer has worsened, he presses the emergency call button 18. Upon receipt of such a signal, the microprocessor 12 generates a corresponding message, which transmits through the transceiver 13, the radio communication channel and the transceiver 7 to the central processor 11. The central processor 11, having received such a message, transmits the corresponding signal to the unit 5 to turn on the sound signal, informing about the presence of an emergency situation in the monitoring area, and also initiates a request to this wearable device 2 for sending in real time the video recording data and sound background from the site of the work of the performer. The data received in response to the request is transmitted by the central processor 11 to the display unit 9 for visual presentation to the dispatching personnel or the responsible operator. This allows the dispatching personnel or the responsible operator to immediately check and, if there is no danger to the life and health of the work performer, disable the action of unit 5 by issuing an appropriate command to the central processor 11 using the data input unit 10.

By means of the data input unit 10, the dispatching personnel or the responsible operator can enter information about a previously unknown hazardous production factor into the central processor 11 for transmission to the unit 6 of the digital map of control zones, if pressing the emergency call button 18 on the wearable device 2 was caused by a meeting of the work performer with a hazardous production factor that was previously unknown.

While maintaining a threat to the life and health of the work performer, the duty dispatching personnel or the responsible operator, using the data input unit 10, enters a command to the central processor 11 to generate a message about the need to provide assistance to the performer indicating his location and transfer to the wearable devices 2 of the work performers located within control zones.

In the absence of a corresponding command from the data input unit 10, the central processor 11 on the schematic plan of the digital map makes changes to designate the coordinates of the location of the wearable device 2 as the coordinates of the unconscious performer. This information is also displayed on the monitor of the display unit 9.

Unit 16 for determining the position of the wearable device is a set of sensors: accelerometer, gyroscope, magnetometer. Based on the data received from these sensors, information about the position of the wearable device 2 in space is formed. With a sharp change in the position of the wearable device 2 in space, which corresponds to a fall of a person: from a height or onto the surface on which he is, including cases caused by loss of consciousness, unit 16 generates a corresponding signal and transmits it to the input of the microprocessor 12. System functioning algorithm in this case, it is the same for the case of pressing the emergency button 18.

To ensure the transfer of a large amount of information stored in the memory unit 14 per shift, the duration of which can be twelve or more hours, the connector 25 of the wearable device 2 of the work performer is connected to the interface unit 24 of the post 1 control and notification after the shift. The dispatching personnel or the responsible operator, using the data input unit 10, enters the appropriate command to the central processor 11, which sends through the interface unit 24 and connector 25 a request to the microprocessor 12 to provide all the archived information from the memory unit 14. This allows the dispatching personnel or the responsible operator to view the archive of video recordings in the future, as well as not to transmit unnecessarily a large amount of data over a wireless communication line in real time.

The system additionally provides control of the movement of rolling stock in the control zones and notification of locomotive crews and drivers.

In one embodiment of the system (see Fig. 2) on a controlled rolling stock 26 with a safety device made on a relay element base, in real time the navigation signal receiver 30 interacts with the GPS / GLONASS satellite navigation system, determines the current coordinates of the rolling stock and transmits them to the input of the transceiver 27, which interacts by radio channel with the transceiver 7 of the control and notification station 1 for transmission to the central processor 11.

The central processor 11, by analyzing data on the current coordinate of the controlled rolling stock 26 and the results of processing video images by the block 4 of control zones, clarifies the coordinates of the location of the controlled rolling stock 26.

Similarly, the current position of the controlled rolling stock 26 is fixed on the schematic plan of the control zones in block 6. When the controlled rolling stock 26 approaches the place indicated on the schematic plan of the control zone as the location of a hazardous production factor or the location of the work performer, the central processor 11 generates a message transmitted through the transceiver 7 over a radio channel and the transceiver 27 to the input of the display unit 28, which displays information about the location of the hazardous production factor and / or the location of the work performer. In this case, block 29 carries out the corresponding notification of the driver.

The display unit 28 is a liquid crystal display located in the driver's cab, the signaling unit 29 is a sound detector also located in the driver's cab.

In another embodiment of the system (see Fig. 3) on a controlled rolling stock 31 with a safety device 33 made on a microprocessor element base, the notification is carried out based on the data of the safety device 33. The existing safety devices CLUB, BLOCK and their modifications have the functionality of displaying information and signaling by means of the indication and signaling units included in them, as well as determining the current coordinate by means of satellite navigation systems due to the unit for determining the coordinates included in their composition. In addition, the safety devices 33 are associated with the braking system of the rolling stock, which allows braking in emergency situations.

The security device 33 transmits the current coordinates of the rolling stock to the input of the transceiver 32, which interacts by radio with the transceiver 7 of the control and notification post 1 for transmission to the central processor 11.

The central processor 11, by analyzing the data on the current coordinate of the rolling stock 31 and the results of processing video images by the control zone unit 4, clarifies the coordinates of the location of the controlled rolling stock 31.

Similarly, the current position of the controlled rolling stock 31 is fixed on the schematic plan of the control zones in block 6. When the controlled rolling stock 31 approaches the place indicated on the schematic plan of the control zone as the location of a hazardous production factor or the location of the work performer, the central processor 11 generates a message , transmitted through the transceiver 7 over the radio channel and the transceiver 32 to the input of the security device 33, on the display unit of which information about the location of the hazardous production factor and / or the location of the work performer is displayed and sound notification is carried out by means of the alarm unit.

Thus, the proposed system automatically monitors and notifies performers in real time during work in hazardous areas, predicts the onset of hazardous production factors in control zones, which allows ensuring the safety of work performers and the safety of rolling stock traffic.
