Description

The invention relates to the field of railway automation, telemechanics and communications and can be used for fencing a place of work and for automated notification of workers on railway tracks about the approach of railway rolling stock without using signalists.

Known warning system about the approach of rolling stock, containing a central control unit, including a receiver of radio signals, collective and individual sirens, sensors for detecting rolling stock, designed to be installed along the way, and connected to them the corresponding radio signal transmitters, with at least four sensors rolling stock detection to accommodate at least two on each track on each side of the track work site, the central control unit is configured to receive radio signals from transmitters with a frequency sufficient to determine the order of starting the activation of rolling stock detection sensors and determine the direction of movement of the train, each sensor for detecting the rolling stock is an ultrasonic sensor designed to be installed on the rail neck, and each radio signal transmitter is a system unit with a built-in signal radio station, connected with one sensor for detecting a rolling stock or with two sensors for detecting a rolling stock located on one side of the track work site (RU 137532 U1, 20.02.2014).

The disadvantage of the known system is that in the presence of the automation of the process of alerting workers about the approach of the rolling stock, there are no means for fencing the boundaries of the work site if obstacles to the movement of the rolling stock arise at the work site.

The closest to the proposed one is a system for fencing the site of work and alerting workers on the railway tracks, which contains sensors for detecting rolling stock installed on the foot of the rail at a given distance on both sides of the boundaries of the work site, each of which is connected by a flexible shielded cable to a radio station, installed near the railway track, radio-controlled portable signaling devices of the fence (RPSO), located at a given distance on both sides of the boundaries of the work site, and a collective portable annunciator installed at the work site, collective portable annunciators installed on track machines, individual portable annunciators , attached to the working, and a collective portable signaling device (KPS), while the RPSO contains red and yellow emitters, a controller, photodetectors for analyzing the radiation, respectively, emitters, a radio station and a power supply unit in the form of a rechargeable battery, the controller outputs are connected to the inputs of the emitters, the inputs are connected to the outputs of the photodetectors, and the input / output is to the output / input of the radio station, and is fixed on a bar mounted vertically on a plate with holes for installing locking locks, and is equipped with a sensor tilt control, the output of which is connected to the controller (RU 2655566 C1, 26.06.2017). This system is taken as a prototype.

The system has the following disadvantages. In accordance with the formula L = Vmax / 60, where Vmax is the maximum permitted train speed on the section of the fence (140 km / h), the sensors should be installed at a distance of 2.3 km from the KPS, which is difficult to achieve in conditions of curved sections or other obstacles for the passage of the radio signal for their guaranteed functioning. The KPS are separately communicated by radio with the sensors and separately with the RPSO. If the connection with the RPSO is not in doubt, since it is closer to the KPS (1000-1700 m), then the radio communication with the sensor (2000-2300 m) under certain conditions can be problematic.

In addition, the disadvantage of the known system is the complexity of the installation of sensors for detecting the rolling stock on the foot of the rails and fencing devices, requiring the participation of at least two people and the duration of work is not less than 10 minutes, especially laborious in winter conditions.

The technical problem solved by the invention is to increase the reliability of the system, ensure the possibility of increasing the distance of the sensor installation from the work site, which allows the system to be used on large sections of the railway infrastructure, as well as simplifying the system, reducing material and operating costs when using it,

The technical result achieved by the invention and allowing to solve the specified problem is to increase the reliability of signal transmission of sensors for detecting rolling stock, including at a large distance from the place of work and on curved track sections.

The technical result is achieved by the fact that the system for fencing the site of work and warning workers on the railway tracks contains sensors for detecting a rolling stock with a radio station, radio-controlled portable signaling devices intended for installation on a rail of a railway track at a given distance on both sides of the boundaries of the work site. placement at a given distance on both sides of the boundaries of the work site, individual portable sirens for each worker on the track and a collective portable signaling device designed for installation at the work site, made with the ability to communicate by radio channel with radio-controlled portable fence signaling devices and individual portable sirens, when this, according to the invention, each radio-controlled portable fence signaling device is configured to relay the signal from the sensor to the collective portable signaling device, and the system with equipped with repeaters to ensure communication of the collective portable signaling device via radio channel through the radio-controlled portable fence signaling device with the corresponding sensor for detecting the rolling stock.

To eliminate the need to use special supports for placing portable fencing devices on the ground, each radio-controlled portable fence signaling device, as well as each repeater, includes a means of fastening to a contact network support,

A preferred embodiment of said fastening means is a lockable flexible fastening strap.

To simplify the installation of the sensor on the rail, a magnet for mounting on the rail neck is built into the housing of each detection sensor, and to simplify the system, a corresponding radio station is built in the housing of each detection sensor.

In a preferred embodiment, the system is equipped with a remote control panel for control and monitoring by radio channel through a collective portable signaling device of radio-controlled portable fence signaling devices.

In addition, the collective portable annunciator and individual portable annunciators are made with frequency switches.

The invention is illustrated by a drawing, which shows a diagram of an embodiment of a system for fencing a work site and warning workers on railway tracks for one direction.

The system for fencing the site of work and notification of workers on the railway tracks (SORBIS-M1) contains sensors 1 for detecting rolling stock (symbol DOP.RSDOP-M) installed on the rail at a given distance on both sides of the work site boundaries (symbol DOP.RSDOP-M), each which is equipped with a radio station (radio modem), radio-controlled portable signaling devices of the fence 2 (RPSO 2), located at a given distance on both sides of the boundaries of the work site, a collective portable signaling device installed at the work site (symbol KPS-L), individual wearable sirens 4 (INO 4) for each worker on the track and a remote control panel 5 (VP 5) of the work manager, as well as two repeaters 6 (RT 6). The drawing shows an area on one side of the work site.

The design of each DOP.RSDOP-M 1 includes a magnet, which is an integral part of the case. DOP.RSDOP-M 1 is installed with a magnet on the rail neck at a distance that a train moving at the maximum speed for a given section passes in at least 60 s. A radio station is also fixed in the DOP.RSDOP-M 1 building.

KPS-L 3 interacts by radio directly with INO 4, VP 5 and RPSO 2, and through RT 6 - with DOP.RSDOP-M 1.

RT 6 and RPSO 2 are placed on the corresponding supports 7 and 8 of the contact network at a certain height with the help of lockable flexible fastening clamps 9. At the same time, RPSO 2 are fixed on the supports 7 of the contact network, located at a distance of 1000-1700 m from the boundaries of the work site, and RT 6 - on both sides of the work site on the supports 8 of the contact network, located at a distance of 100-300 meters from DOP.RSDOP-M 1.

RT 6 are used to ensure guaranteed radio communication between DOP.RSDOP-M 1 and KPS-L 3, especially on curved sections of railway tracks, where there can be two or more of them (RT 6).

Each RPSO 2 contains emitters of red and yellow colors, a controller, photodetectors for analyzing the radiation of the emitters, respectively, a radio station and a power supply in the form of a rechargeable battery, while the controller outputs are connected to the inputs of the emitters, the inputs are connected to the outputs of the photodetectors, and the input / output is to the output / radio station input (not shown in the drawing). The radio station is made with a repeater function, which is provided by the corresponding software (SW) of the controller.

RPSO 2 provides fencing of the work site on the stretch by giving the locomotive driver an optical signal that requires the rolling stock to stop at the border of the work site, where there is an obstacle to movement, or a signal that allows movement at a set speed. In this case, RPSO 2 additionally performs the function of relaying the radio signal in the signal transmission chain from KPS-L 3 to DOP.RSDOP-M 1 and back, both in the presence of RT 6 in the chain and in their absence. The retransmission function in RPSO 2 is turned on automatically if necessary, which is provided by the software. If the signal level from KPS-L 3 to DOP.RSDOP-M 1 is sufficient, the signal is transmitted directly, bypassing RPSO 2, and if not enough, then the signal is transmitted through RPSO 2.

RPSO 2 also has a memory and a status record (red, yellow, battery discharge, failure) of a light element linked to real time and Glonass / GPS coordinates with the possibility of subsequent reading and copying of the archive to an external medium.

Structurally, KPS-L 3 can be made in the form of a known collective portable device containing a control device, a generator of acoustic monitoring and warning signals, an amplifier and a loudspeaker, as well as an optical emitter connected to another output of the control device, an analyzing device, connected to the input of the device control device, a transceiver, the input / output of which is connected to the output / input of the control device, and a microphone installed in the immediate vicinity of the loudspeaker connected to the input of the analyzing device (see, for example, RU 2583011 C1, 27.06.2016).

KPS-L 3 provides reproduction of audio and optical control signals, audio and optical warning signals, analysis of the quality of reproduced acoustic signals and transmission of information about normal operation or failure of RPSO 2 via a radio channel to VP 5.

INO 4 is designed for individual notification of a railway worker about the approach of railway rolling stock. INO 4 is provided for workers whose location or conditions of work performance worsen the conditions for the perception of the notification from KPS-L 3.

INO 4 provides reception of radio signals and reproduction of sound, vibration and optical alert signals when receiving KPS-L 3 alert signals over the radio channel. Reception of control signals is indicated by the INO 4 optical indicator.

At the same time, KPS-L 3 can be equipped with an automatic sound level control system depending on the noise level in the notification area, which ensures that the useful signal level exceeds the average noise level by 10 dB, but not higher than 120 dB.

KPS-L 3 has a frequency switch, and if the working frequency is busy at the place of work or there is interference on it, you can quickly switch to other pre-programmed frequencies. There are six frequencies in total. When switching the frequency to KPS-L 3, all other devices in the system automatically receive a command and switch to this frequency, except for INO 4. INO 4 also has a switch for six frequencies. The frequencies of INO 4 and KPS-L 3 must match. When switching to INO 4 and KPS-L 3, the channel number is announced by speech.

The VP 5 of the work manager is made with the ability to control by radio channel through the KPS-L 3 RPSO 2. In addition, the VP 5 has a control indication that displays what color the RPSO 2 is on, and an indication of its failure. VP 5 also has direction indication (busy, unoccupied), voice, sound and vibration notification of rolling stock detection. On VP 6 there is a button that manually triggers an alert on KPS-L 3 and INO 4. There is also a button to cancel the playback of the alert signal. VP 6 has a memory and recording of events (on / off the VP, on / off the signal, the state of the RPSO, etc.) with reference to real time and the coordinates of Glonass / GPS with the possibility of subsequent reading and copying of the archive to an external medium.

The system for fencing the site of work and warning workers on the railway tracks works as follows.

Before starting work, DOP.RSDOP-M 1 is installed with a magnet on the rail neck at a given distance on both sides of the work site. RPSO 2 and RT 6 are fixed respectively on the supports 7 and 8 of the contact network on both sides of the work site. These operations do not require time-consuming labor. KPS-L 3 is located at the work site and supplies the working INO 4. The work manager is equipped with VP 5.

After installing DOP.RSDOP-M 1, RT 6, RPSO 2, their work is activated by turning on the power on each device. To do this, insert the key into the slot on each device and turn it to the appropriate position. After installing and turning on all devices, including VP 5, you must also turn on the KPS-L 3 with the key and press the "NU" button (initial setting). After that, KPS-L 3 interrogates all devices, and the status indication of each device lights up on its front panel. Green indicator - there is radio communication, the device is working properly; red - there is radio communication, the device is not working properly; the indicator does not light up - there is no radio communication.

In the absence of rolling stock, the DOP.RSDOP-M 1 sensor generates and transmits through its radio station through the RT 6 repeater and through the RPSO 2 to the KPS-L 3 signals, upon receipt of which the KPS-L 3 reproduces sound and optical control signals, and upon detecting a mobile composition DOP.RSDOP-M 1 generates and transmits through RT 6 and RPSO 2 signals, upon receipt of which KPS-L 3 reproduces the alert signal.

Alert signals coming from the radio station of each DOP.RSDOP-M 1 contain information about the direction of movement of the rolling stock approaching the place of work.

Control signals and warning signals are broadcast by KPS-L 3 via a radio channel to INO 4, which are reproduced by them in the form of sound, optical and vibration signals.

Control signals are sent to KPS-L 3 from each DOP.RSDOP-M 1 in different time intervals, confirming the absence of rolling stock in each direction.

KPS-L 3, based on information about the absence of rolling stock, reproduces a common tone and optical control signal from two directions.

When one of the DOP.RSDOP-M 1 detects an approaching rolling stock, the corresponding radio station stops transmitting the control signal and generates an alert signal, which transmits over the radio channel through RT 6 and RPSO 2 to KPS-L 3. The alert signal is reproduced by a loudspeaker and the corresponding KPS optical emitter -L 3.

The playback of the warning signal continues from the moment the rolling stock is detected until the end of its passage by the sensors DOP.RSDOP-M 1 plus an additional 7-10 s.

It is allowed to start work only after the rolling stock has followed the place of work.

In this case, at the beginning of the reproduction of the warning signal, KPS-L 3 generates a speech signal reproduced by a loudspeaker containing a message about the direction along which the train is approaching.

The speech signal that will be played back can be quickly recorded for an unambiguous understanding of where the train is coming from. For example - “Attention! Train from Moscow! " or "Train on the first track!" To record a speech signal on the KPS-L 3, a microphone headset is provided.

If, during the playback of an alert about the approach of rolling stock from one of the directions, a rolling stock approaching from another direction is detected on a double-track section, KPS-L 3 reproduces a voice message through the loudspeaker about the direction of movement of the detected rolling stock.

The direction of movement of the approaching rolling stock is indicated on the KPS-L 3 control and display panel by appropriate optical indicators.

If the communication between KPS-L 3 and one of the DOP.RSDOP-M 1 fails as a result of the termination of the control signals, KPS-L 3 turns on the alarm. At the same time, information about the failure of a specific DOP.RSDOP-M 1 appears on its control and display panel.

Monitoring and warning signals KPS-L 3 automatically transmits over the radio channel to INO 4, which reproduce optical control signals and sound, optical and vibration warning signals within the work site.

In order to increase the reliability, KPS-L 3 automatically compares the reproduced signals with the received signals and, if they do not coincide, reproduces the alarm signal.

If there are obstacles to movement at the work site, the head, using the control elements KPS-L 3 or VP 5 through KPS-L 3, sets the appropriate control signal and transmits it by radio to RPSO 2 to form and turn on a prohibiting indication that requires the train to stop at the border places of work. In the absence of obstacles to movement at the work site, KPS-L 3 or VP 5 transmits a control signal via the KPS-L 3 to RPSO 2 via a radio channel to generate and turn on an indication that allows the train to move at a set speed.

RPSO 2, having received the control signal from VP 5, forms the corresponding indication of the emitters. To form a prohibiting indication, the RPSO 2 controller supplies a pulsed supply voltage to a red emitter, and when a permitting indication is formed, to a yellow emitter. In either case, red and yellow emitters work in a flashing mode.

In this case, the RPSO 2 photodetectors control the operation of the emitters. In the radiation mode, a signal is generated at the output of the corresponding photodetector, which is fed to the corresponding input of the controller. The controller transmits to the radio station the corresponding acknowledgment signal as control signals for transmission over the radio channel to KPS-L 3.

The KPS-L 3 radio station automatically reproduces an acknowledgment signal from each RPSO 2 and transmits it to the control controller, which compares it with a given control signal and generates a corresponding signal, which transmits via the radio channel to VP 5. If the signals do not match, the KPS-L 3 generates a tone Emergency Signal.

When confirming the prohibiting indication of each RPSO 2 on the VP 5 panel, the signal indicators of each direction of movement emit a red flashing light, and when the permissive indication is confirmed, they emit a yellow flashing light.

If communication with RPSO 2 is broken or when an acknowledgment signal is received that does not correspond to the transmitted control signal, the signal indicator on the VP 5 panel starts to glow blue, on the KPS-L 3 panel the corresponding indicator starts to glow red and KPS-L 3 plays an audible alarm ...

Each DOP.RSDOP-M 1, RPSO 2 and RT 6 provides for the presence of a gyroscope to control the initial (after turning on the device) position. In the event of a change in its position (fall, theft), an alarm sounds on the KPS-L 3, and the indicator of the device changes to red.

Thus, the proposed technical solution ensures traffic safety and the safety of those working on railway tracks as a result of reducing the impact of the human factor on their provision, which also makes it possible to increase labor productivity when carrying out repair work and current maintenance of railway infrastructure facilities by simplifying the process of installing rolling stock detection sensors. and fencing devices.
