Description

The utility model relates to the field of railway transport and can be used in devices to alert service personnel about the approach of a train.

The closest in technical essence and the achieved effect is a device for alerting service personnel about the approach of a train, described in the patent for the invention of the Russian Federation No. 2070123 "Device for fencing the place of work on the railway" M class. 6 B61L 23/06 publ. 12/10/1993, which includes an information processing unit with sound and information alarms connected to it and sensors for determining the location of the train installed on tracks outside the control zone.

The disadvantage of this device is that connecting the device to rail circuits, the signals from which are taken as signals from sensors to determine the location of the train, interferes with the operation of rail circuits and affects the safety of train traffic.

Another disadvantage of the device is that it does not record the operation of the device and cannot be used in the investigation of an accident that occurred during the work of maintenance personnel on railway tracks, which reduces its functionality.

The objective of this utility model is to increase the safety of train traffic and the expansion of functionality.

The problem is solved in that in the device for alerting staff about the approach of the train, including an information processing unit with sound and information alarms connected to it and sensors for determining the location of the train installed on tracks outside the control zone, optocoupler galvanic isolation is introduced through which the processing unit information is connected to the sensors for determining the location of the train and the event logger connected to the output of the information processing unit.

This embodiment of the device, in which the optocoupler isolation is introduced, through which the information processing unit is connected to the sensors for determining the location of the train and the event recorder connected to the output of the information processing unit, allows the introduction of the optocoupler isolation to minimize the effect of the device on the operation of the rail circuits and thereby thereby improving the safety of train traffic, and the presence of an event recorder allows you to record the operation of the device during the operation of the attendant Staff at the track and in the event of an accident event recorder testimony may be used in the investigation, which increases the functionality of the device.

A device for alerting service personnel about the approach of a train contains an information processing unit 1 with signaling devices connected to it: sound, in the form of a loudspeaker 2 and a siren 3 and an information board 4 with sirens 3 placed on it, an indicator 5 “Train”, track numbers 6 and indicators 7 direction of movement of the rolling stock. Sensors 8 determine the location of the train, installed on tracks 9 outside the control zone. The information processing unit 1 is connected to the sensors 8 determine the location

trains through optocoupler isolation 10. Event logger 11 is connected to the output of information processing unit 1.

The device operates as follows.

The information processing unit 1 controls the entire device. It receives information from the sensors 8 to determine the location of the train and generates output audio and information signals. When you turn on the unit 1 for processing information, the device goes into standby mode. There are no luminous signals on the information board 4. Loudspeaker 2 every 15 sec. gives a control signal with a frequency of 300 Hz and a duration of 1-1.5 seconds. The device is ready for work and maintenance personnel can start work on the tracks. The control signal informs the operating personnel about the operability of the device. The absence of a control signal from loudspeaker 2 in the presence of a train in the area approaching the control zone indicates the inoperability of the device. At the same time, service personnel must immediately leave the place of work. When a train enters the control zone, the device enters the train availability mode. On the information board 4, the direction indicators 7 light up, the indicator 5 for the presence of the train in the control zone starts flashing, and information appears on which track number 6 the train is approaching. Sirens 3 sound every 4 seconds for 1.5 seconds. Loudspeaker 2 reproduces a tell-tale and voice information about an approaching train. The voice message contains information about the approaching train and its direction and is repeated every 16 seconds. When signaling sirens 3 and a voice message about the approach of a train, maintenance personnel must leave the place of work on the tracks and, pressing the “Confirm” button on the information processing unit 1, confirm that the signal about the approach of the train is heard and from this moment the signal of sirens 3 stops, but loudspeaker 2 continues to signal the approach of a train. Signals

in loudspeaker 2 stop only after the last unit of the rolling stock leaves the control zone and only after that it is possible to continue the work of maintenance personnel on the tracks.

Simultaneously with turning the device on and off, the event recorder 11 turns on and off. The event recorder 11 has four operating modes. In the date and time setting mode, the current date is set, then the time: hours, minutes, seconds. After setting the time, the device automatically switches to the mode of storing information about passing trains. In this mode, events are recorded in the memory: turning on the device, entering the train, pressing the “Confirm” button, leaving the train, malfunctioning of the information processing unit 1, turning off the device. In the memory of the recorder 11 events are stored up to 99 events. Each new event is recorded in place of the oldest. The mode of transmitting information from the memory of the recorder 11 events to the computer occurs when a connection is established with the computer and the reception program is launched on it. In the mode of viewing recorded events, information on trains passing through the control zone is viewed on the display.
