Description

The invention relates to regulatory or warning devices installed along the route of locomotives or trains, namely, traffic lights that regulate the movement of trains.

Three-digit traffic lights are known in which incandescent lamps are used as the emitting element, which are connected to power supplies by the contacts of the corresponding signal relays, and the color of the traffic light is determined by a specially installed light filter (Railway Automation and Telemechanics Systems: Textbook for High Schools / Yu.A. Kravtsov, V .L. Nesterov, G.F. Lekuta et al .; Edited by Yu.A. Kravtsov. - M.: Transport, 1996.- P. 68, Fig. 4.1).

The disadvantages of these devices is the low reliability due to the short service life of incandescent lamps and the effect of vibration from passing trains on the lamp, which leads to premature failure of incandescent lamps.

Known traffic lights of railway transport in which LEDs are used as a radiating element [Patent "THREE-VALUE LED LIGHT" No. 2239575, RF, Sergeev BS, Savelyev E.O.].

The closest in technical execution to the proposed device is the device [Patent "FIVE-VALUE LED LIGHT" No. 2278417, RF, Saveliev E.O.].

The disadvantages of this device are:

- reducing the intensity of the glow of the green LED circuit while turning on red;

- reducing the intensity of the glow of the LED circuit in green and red while turning on green, blue and red;

- the need for a separate installation of LEDs for each color;

- the inability to control more than five indications (red, green, yellow, white, blue), for example, the input traffic light can transmit 13 signals to the train driver (Operational basics of automation and telemechanics. A textbook for universities of railway transport. Vl. V. Sapozhnikov et al. - M.: Route, 2006. - 247 p., p. 30).

The claimed device is aimed at solving the problem of simplifying traffic lights by replacing several single-color LEDs with one multi-color and increasing the number of signal indications of a traffic light.

A multi-color LED consists of K LEDs of various colors located in one housing and has a K + 1 pin.

The essence of the invention lies in the fact that in the device, characterized in that M multi-color LEDs are introduced into it, the inputs of the device are control inputs and a common input, each control input is connected to M anodes of the same color of multi-color LEDs, the common input is connected to M cathodes of multi-color LEDs , the light reading is determined by mixing K the colors of the LEDs included in the multicolor LEDs.

A functional diagram of the device is shown in FIG. one.

The device consists of multi-color LEDs 1 _i , i = l, ..., M.

The inputs of the device are the control inputs U ₁ ... U _K and the common input O.

Each control input is connected to M anodes of the same color of multi-color LEDs.

Common input O is connected to the M cathodes of multi-color LEDs.

The operation of the device is based on the inclusion of one or several LEDs (as part of a multi-color LED) with a different glow color. The light reading is determined by mixing K the colors of the LEDs included in the multi-color LEDs.

Thus, using multi-color LEDs having K colors, 2 ^K signal readings can be obtained, with one signal reading corresponding to a turned off traffic light.

The device operates as follows.

At the input O low potential is applied.

When applying simultaneously low voltage to all inputs U ₁ ... U _K, all LEDs of multi-valued LEDs are off. There will be no light indication (traffic light off).

When high potential is applied to one of the control inputs U _i in all multi-valued LEDs 1 ₁ ... 1 _M , the i-th LEDs turn on. The light reading corresponds to the color of the LEDs turned on for multi-color LEDs.

When high potential is applied to several inputs U ₁ ... U _K simultaneously, in all multi-valued LEDs 1 ₁ ... 1 _M , LEDs are turned on, the high potential of which is applied to the anodes. The light reading will be determined by the color mixing of the on LEDs of the multi-color LEDs.

Thus, when applying a combination of high potentials to the control inputs U ₁ ... U _{K, the} light reading of the device will be determined by mixing the colors of the turned-on LEDs of multi-color LEDs.

The simplicity of this N-digit traffic light and a wide range of signal readings make it a very promising means of regulating the movement of trains.
