Description

The invention relates to railway automation and can be used in systems for ensuring the safety of train traffic, in particular, to automatically warn the locomotive driver about the threat of a collision of rolling stock during shunting operations with objects such as a dead-end stop of a railway track, prohibiting a traffic signal, a busy railway way and others. Such situations arise when wagons are fed to loading sites where there is no through passage, and a diesel locomotive, electric locomotive, and other traction rolling stock (hereinafter diesel locomotive) cannot leave the railway track, and the shunting operation of the rolling stock is possible only by the locomotive feeding the cars forward.

A device for automatic control of train braking is known from the prior art (SU 1255485, IPC V60T 8/58, publ. 09/07/1986), containing a transmitting antenna located at the beginning of the block section, connected to a track generator, and on the locomotive - a receiving antenna, connected to the information receiving unit, a speed sensor connected to the first input of the first path meter and to a speed controller connected to the executive unit, and the second path meter connected to the first input to the output of the speed sensor, the second input to the first output of the information receiving unit. The device also contains an AND element connected by one input to the zero output of the first path meter, the other - to the other output of the executive unit, an OR element connected by the output to the second input of the first path meter, the first input to the second output of the information receiving unit, the second to the output element And, connected by the third input to the output of the second measuring device.

The disadvantage of this device is the limited functionality, as well as the impossibility of its functioning when the train is moving forward by cars, which is necessary when shunting.

A known system for monitoring and alerting about the approach of rolling stock (RU 2467902, IPC B61L 23/00, publ. 11/27/2012), containing a central control center, in which the interconnected application server and radio communication server, on-board units of rolling units, units individual notification, track control units installed near the rails in the places of point control of the approach of mobile units. Each control unit consists of a self-testing track sensor of the passage of wheels of mobile units, connected by two-way communication with a combined radio communication transceiver and a self-organizing network transceiver. Each unit of individual notification includes a microprocessor module of a self-organizing communication network transceiver and a switch for setting the operating mode.

The disadvantage of the system is the complexity of technical implementation due to the obligatory connection to data transmission networks, the need for a GSM cellular network with appropriate equipment, low accuracy in determining GPS coordinates, the need to connect to power supply networks. Also, the disadvantage of the known system is the impossibility of its functioning when the train is moving forward by cars, which is necessary when shunting.

A known system for regulating the movement of a train on the stretch (RU 2548645, IPC B61L 23/00, publ. 20.04.2015), containing stationary kits, each of which consists of a computing device for an automated workstation of an electromechanical and a computing device for an automated workstation for a station attendant , the first and second CAN-interface, control module, interface module, electrical interlocking module, module for monitoring signals of rail lines and automatic locomotive signaling, inter-office communication module. The locomotive is equipped with an integrated locomotive safety device, a transceiver, and a train brake system control module. Additionally, each stationary set includes a radio interface module and an automatic crossing signaling module, which are connected to the computing device of the station attendant's workstation and the control module through the first CAN interface. The locomotive is equipped with a radio signal processing module connected to the indicator, while the input of the radio signal processing module is connected via the CAN interface to the output of the transceiver and the output of the integrated locomotive safety device.

The disadvantage of the system is the complexity of operation and high cost, since it requires the presence of additional jobs of an electromechanic and a duty officer equipped with computing devices, a module for logical processing of signals on a locomotive, a system of railway automation and telemechanics. In addition, the functionality of the system is limited, since it does not provide control and regulation of the rolling stock when moving its cars forward.

The objective of the invention is to create a simple, easy-to-use and reliable rolling stock control system.

The technical result of the invention consists in expanding the functionality of the system, providing improved maneuverability of rolling stock on railway tracks, including when moving cars forward.

The technical result of the invention is achieved by a system for monitoring and warning about the threat of a collision of rolling stock during shunting operations with an obstacle in the form of a dead-end stop or a prohibitory signal of a traffic light, including inductive track control sensors installed in the control zones of technological objects near the rails along the ridge of a wheel pair, a solar battery with a panel mounted on the frame, an electronic switching device located inside a switch cabinet mounted on the frame, which contains a control unit, electrical control circuits of inductive sensors for track control and traffic light signals, batteries, a controller for controlling the charge-discharge of batteries, a radio transmitter with an antenna, and inductive sensors for directional control and traffic lights are connected to electrical control circuits by means of a connecting cable.

According to the invention, two inductive directional sensors can be used in each obstacle monitoring zone.

The essence of the invention is illustrated by drawings, where FIG. 1 shows a schematic diagram of a system for monitoring and warning about the threat of collision of a rolling stock with an obstacle, FIG. 2 is a block diagram of the electronic switching device of the system.

The system (Fig. 1) contains inductive sensors for track control 1, connected by means of a cable 2 to the switching-electronic device 3, to which the solar battery is also connected 4. Technological objects are indicated on the schematic diagram: traffic lights 5, dead-end stops 6, rolling stock with shunting diesel locomotives 7, which are equipped with radio stations, railway track No. 1 and railway track No. 2.

The switching-electronic device (Fig. 2) is located inside the switching cabinet 8 and contains a control unit 9, electrical control circuits 10 of inductive sensors and traffic lights, batteries 11, a controller for controlling 12 charging-discharging batteries, a radio transmitter 13 with an antenna 14. Control controller 12 is connected by an electric circuit with a solar battery 4.

The system is powered from an autonomous power supply set based on a solar battery; it also provides the ability to connect to an external power supply from an alternating current network, with a voltage of 220 V (not indicated in the drawing). The solar panel is mounted on a special frame. The communication cabinet is installed and fixed on a special frame directly next to the solar panel.

Inductive sensors 1 are installed in the control zones, that is, in front of the installation site of traffic lights 5 and near the dead-end stops (prisms) 6 to control and prevent the passage of a red light, collision with a dead-end prism and derailing of the rolling stock. Inductive sensors work without direct contact with the wheelset and have an increased service life. As inductive sensors can be used, for example, VBI sensors - http://www.elconnect.ru/production/engage/vbe/.

Inductive sensors - are used for contactless receipt of information about the movements of the working bodies of machines, mechanisms, robots, etc. and the conversion of this information into an electrical signal. The principle of operation of the inductive sensor is based on a change in the inductance of the winding on the magnetic circuit, depending on the position of the individual elements of the magnetic circuit (armature, core, etc.). In such sensors, linear or angular movement is converted into a change in the inductance of the sensor. They are used for measuring angular and linear displacements, deformations, dimensional control, etc.

In each obstacle monitoring zone, two inductive directional sensors can be used.

The system operates if the rolling stock is in the control zone of the inductive sensors by its front wheelset, in the direction of travel, in front of a traffic light with a prohibiting signal or without a signal. The voice message transmitted by the system over the radio channel carries the following information: "Attention, prohibiting the traffic signal, railway track No. 1 (No. 2)", and when approaching the dead-end stop - "Dead-end prism of the railway track. Attention". The command transmission should be carried out when the wheelset of the rolling stock enters the control zone of the inductive sensors.

In this case, the driver of the shunting diesel locomotive must immediately stop the train, contact the head of the shunting work.

The system works as follows.

When the wheelset of the railway rolling stock enters the monitoring zone of the sensors 1, the sensor is triggered with the closure of the corresponding electrical control circuit 10 connected to the control unit 9, which analyzes the belonging of the corresponding closed electrical circuit and issues the corresponding command assigned to this electrical circuit to the radio transmitter 13, which transmits via a programmed radio channel, voice information into the air at a programmed radio frequency. An antenna 14 with corresponding radio frequency characteristics is used to amplify the radio signal. Radio frequencies are programmed depending on the selected radio frequency of the railway transport enterprise. Control circuits 10 signals of traffic lights 5 are designed to switch modes (active / inactive) of sensors 1 located at the traffic lights. With a permitting traffic light (green) and the passage of the wheelset of the sensor control zone 1, the system does not register a violation of the technological mode of operation and does not transmit an information message over the air. In case of a prohibiting traffic light (red) and the passage of the wheel pair of the sensor control zone, the system detects a violation of the technological mode of operation and transmits an information message over the air.

Sensors 1, located at the end of the overpass near dead-end prisms 6, do not depend on the readings of traffic lights 5, and each time a wheelset of a railway rolling stock passes through the monitoring zone of these sensors, the system transmits warning voice messages via a radio channel.

The electrical power supply of the system equipment is carried out from the storage batteries 11 installed in the switch cabinet 8. The batteries are charged from the solar battery 4 located outside the switch cabinet. The controller for charge-discharge control 12 provides stabilization of the charging current of the storage batteries 11 and stabilization of the supply voltage of the system equipment.

Solar battery 4 allows you to provide power to the system in the absence of the ability to connect to external power supply of industrial voltage If it is possible to connect the system to external power grids, the use of a solar battery can be excluded.

Thus, the proposed invention makes it possible, through a simple, easy-to-use system for monitoring and warning about the threat of collision of rolling stock with an obstacle, to ensure reliable shunting operation of rolling stock on railway tracks, even on those where there is no through passage.
