Abstract

The invention relates to signaling and can be used to control the embarkation and disembarkation of passengers in railway transport. The aim of the invention is to increase functional reliability. The goal is achieved in that the device containing the first optical emitter 3 and terminals 17 of the on-board power supply network, includes a power supply 1, a pulse generator 2, N-1 optical emitters 3, N photodetectors 4, N amplifiers 5, a driver for 6 pulses, N detectors 7 of the pulse sequence with the closing output contact 8 and the alarm unit 9, which contains the signal lamps 10, 11, the auxiliary relay 12 with the closing contacts 13, 14, the door open button 15 and the speed sensor disconnecting contact 16. Optical emitters 3 and photodetectors 4 are arranged in pairs so that the optical communication line between them crosses the controlled hazardous zones: the near-door and inter-car space of the train. In the absence of passengers in the danger zone, signals from the optical emitter 3 are freely transmitted to the corresponding photodetector 4 and then through the amplifier 5 and the driver 6 of the pulses to the detector 7 of the pulse sequence, the contact 8 of which closes and closes the power supply circuit of the signal lamps 10, 11, after which the driver closes the door and starts moving. When a certain speed is reached, the speed sensor contact 16 opens, auxiliary relay 12 releases and turns off the device power. 2 Il.

The invention relates to the field of signaling and can be used to control the embarkation and disembarkation of passengers on railway transport.

The purpose of the invention is to increase the functional reliability of the device.

FIG. 1 shows a functional diagram of the device for monitoring the embarkation and disembarkation of passengers in FIG. 2; an arrangement diagram for pairs of an optical emitter-photodetector on a vehicle.

The device contains a power source 1, generators 2, -2f, pulses, optical emitters 3, -3 ", photodetectors A, -4", amplifiers, drivers of bd-b pulses, detectors 7d-7 "of a pulse sequence, made in the form of a relay with release closure with closing contacts, and an alarm unit 9 containing signal lamps 10 and 11, an executive relay 12 with closing contacts 13 and 14, a door-opening button 15, a softening contact 16 of the speed sensor and an on-board supply network 17.

Optical emitters 3 and photodetectors 4 are arranged in pairs on opposite sides of the monitor. part of the space, for example, a roundabout and intercarriage space of the train. In this case, the optical emitter of 3 pairs is fixed near the door of one car, and the photodetector 4 is fixed near the door of the adjacent car and handles in the direction of the doorway and inter-wagon space (Fig. 2, where the positions 18 and 19 denote Baroiib and the doors of the cars) DP control for embarking and disembarking passengers requires one device on each side of the train,

The device works as follows.

When the train is completely stopped, the driver on} K1 switches button 15 (without self-return.), Which closes the door control circuit of the pneumatic valve (not shown). At the same time, the auxiliary relay 12 triggers, the closure contacts 13 and 14. This energizes the generators 2, 2p wires, the gain | 1 (1 and the drivers 6, -6p pulses. If at least one passenger in the Controlled zone then the corresponding photodetector 4

the signal from the optical emitter 3 is not received, there are no pulses at the input of relay 7, and contact 8 is in the open state, as a result of which the power supply circuit of signal lamps 10 and 11 (respectively, in the first and second driver's cabs) is open. The lack of illumination of signal lamps 10 and 11 indicates that they are in the danger zone.

In the absence of passengers in the danger zone, the signal from the optical emitter 3 is fed to the photodetector 4 amplified by the amplifier 5 and through the driver 6, the pulses are fed to the relay 7. In the presence of a pulse sequence, the output terminal 8 of the specified relay is closed. When all controlled areas are free from passengers, all contacts 1 to 8j-8t are closed, and the signal lamps 10 and 11 are supplied with power from the on-board supply network,

In the presence of luminescence of the indicated lamps, the driver depresses the -button 15, the actuator actuates the pneumatic drive of the doors, and begins to move. Hazardous zones monitoring continues until contact 16 of the speed sensor (when a speed of 10 km / h is reached), after which the auxiliary relay 12 releases and opens its contacts 13 and 14. At the same time, the power supply to the generators, pulses, amplifiers 5 is turned off. -5, and drivers 6; (- b (, the power supply circuit of signal lamps 10 and 11 opens,
