The proposed method of lighting control train stopping point relates to railway equipment, and specifically to devices lighting control stopping points.
This offer is industrially applicable as the technical essence of the method of controlling the light rail stop is performed using the currently known in the technique of structural elements, techniques and methods.
A prior art method of lighting control train stopping point applies to auxiliary rail equipment, in particular to an integrated method of control of lighting at bus stops in the dark.
Today, from the information made public before the priority date of, you know, a similar proposal RU # 28850, U1 IPC: B60L1/14, B60L1/16 "automatic lighting control railway platforms", which in this case is a prototype.
The disadvantage of this proposal is that it is a device to control light railway platforms controlled by the audio signal which is fed manually by the crew approaching the stopping point of locomotive rolling stock. I.e., this device can no longer be considered a machine is ical, because it depends on the human factor. In addition, signal horn locomotive may not always be a source of control devices detect the presence of an approaching train transport, as these sources can be any sound signals of similar frequency with the locomotive horn. In addition, the frequency of the sound signal of a locomotive depends on the type and brand of the locomotive, for this range filter bandwidth determining signal should be wide to accommodate all types of frequency signals railway traction devices (locomotives) of different brands.
The proposed solution does not depend on the human factor, since the detection sensor, proximity rolling stock works from the locomotive spotlight, which is always enabled during operation of any railway vehicle.
The proposed solution is aimed at reducing electricity consumption at the expense of performance lighting control stop upon approaching the rolling stock and only in the dark. In addition, due to the automatic light alarm occurs, the notification of the passengers at the stop point of the approach of rolling stock, resulting in increased passenger safety.
T is Henichesk the result when using the method of controlling the light rail stop is to reduce energy consumption and increase the safety of passengers.
The proposed method of lighting control train stop is applied is illustrated by the scheme lies in the fact that it consists of:
the photosensitive element 1, 2, 3; a processing device of photosensors (WAFD) - 4; switch lighting devices (PPC) - 5; a determination device the night-time (OOD/N) - 6; a lighting device (EE) - 7.
The method of controlling the light rail stop is carried out in such a way that when approaching locomotive rolling stock to a stopping point its headlight of the locomotive, which is always enabled, illuminates the photosensitive element 1, which is a sensor to control the switching circuit lighting at the stop point, which consists of WAFD (processing device of photosensors) 4 and KUO (switch devices lighting) 5. To determine the night-time, the circuit includes one photosensitive element 3, which is the sensor for WAD/N (device definitions the night-time) 6, which gives the command to KUO 5, to enable UO (lighting) 7 only upon the occurrence of the dark time of the day. Thus, the lighting at the stopping point will be included only in the case when the dark and to stop the item will fit the engine.
In order to determine the possible fact stop rolling at the stop point, which may be the only passenger train, front head floodlight locomotive is another photosensitive element 2, which is the sensor, which performs the same function as the photosensitive element 1, in addition, it determines the delay time of the rolling stock at the stop point.
To determine the lighting time stopping points in the KUO scheme 5 includes an electronic timer (figure not labeled), which is determined by the fact of the departure of the locomotive with stopping points and General lighting which is disabled.
1. The method of controlling the light rail stop is made that the command for automatic switching of lighting fixtures stop is served from a photosensitive element, covered head floodlight locomotive rolling stock, the dark is determined by the other light sensitive element that gives the command to automatically turn on lighting, so the lighting will be included only in the case when the dark and to stop the item will fit the engine.
2. The method according to p. 1, characterized in that the process of lighting stopping point is determined by the electronic timer is provided passing locomotive p. the movable partition structure without stopping.
3. The method according to p. 1, characterized in that in the case of stop rolling time renewal process lighting is determined by the light-sensitive element made in the form of a sensor mounted on a stopping point before the main spotlight of the locomotive.
