The device relates to railway automation and can be used to control train and shunting movements.

A device is known for determining the distance traveled by a locomotive, comprising a motion sensor mounted on the locomotive, a pulse generator, an information input register, an adder, a path to speed conversion unit connected to a speed indicator by an output, a recorder. .

The purpose of the invention is to increase reliability.

This goal is achieved in that the device containing a motion sensor installed on the locomotive, a pulse generator, an information input register, an adder, a path to speed conversion unit connected to a speed indicator by an output, the recorder is equipped with counting registers connected by sync inputs to the output of the pulse generator, and outputs, respectively - with one input of the path to speed converting unit and the adder, the input of the last of which is connected to the recorder and the information input of the second counting a register, and the output of the path-to-speed conversion unit is connected to the information input of the first counting register and another adder input, the second input to the output of the information input register, and the control input to the sign output of the displacement sensor, the information outputs and synchronization output of which are connected respectively to information inputs synchronization input register information input, and the displacement sensor has a housing and located in it vertically oriented and spring-loaded relative to the side walls approx perpendicular to the longitudinal axis of the body plate, and wherein the longitudinal axis of the housing parallel to the axis of the locomotive, and in the plate rows are arranged mirror reflectors and on the side walls of the housing, coaxially with the parallel plate specular reflectors mounted optronic elements, outputs of which are formed of the sensor outputs.

Figure 1 shows the location of the reflectors on the screen and the location of the optocouplers; figure 2 presents the electrical diagram of the proposed device; in FIG. 3 shows an embodiment of an adder.

The device comprises a screen 1 with a strip of reflectors 1.1, reflectors for the formation of clock pulses 1.2 and reflectors for controlling the deviation

screen 1.3. The housing 2 is connected to the spring 3. The photodiodes of the optocouplers 4 are connected through resistors 5 to the positive pole of the power supply 6 and are connected to the input

register 7. The outputs of registers 8 and 9 are respectively connected to the inputs of the adders 10 and 11, the outputs of which are connected respectively to the inputs of the speed indicators 12 and path 13. The generator 14 is connected to the input of the register 8. In the initial state, the springs 3 hold screen 1 on average position. In this case, the photodiode 4 is closed, one element 4 is open, the remaining photodiodes are closed.

5 The device operates as follows.

When the button is pressed briefly, registers 8 and 9 are reset. The sync inputs of the registers mentioned above receive pulses from the generator 14, which makes it possible to record information in these registers. The output of adder 10 along all lines has false zeros. From the output of the adder 11 to the input of the indicator 13, as well as

5 from the output of adder 10 to the input of indicator 12, logical zeros are received along all lines. Both indicators show zero. First of movement, the screen 1 moves to the left. In this case, one diode 4

0 is closed; and the second diode 4 is periodically opened in accordance with the magnitude of the acceleration. Each time the photodiode is moved over one of the reflectors 1, new information is entered into register 7. At the time of speeding up, the first diode 4 is closed and the adder 10 operates in the addition mode. For each edge of the pulse from the generator 14, a new number is added to the value of the number in the adder 10, which is written in register 7. For example, if zero was written in the register 8, then due to the other input of the adder 10 at its output, The number corresponding to the state of register is 7.

5 pulse from the output of the generator 14 in the register 8 will be written the number from the output of the adder and the output will add the sum of two numbers. If the motion is uniformly accelerated, then the optron row is above one column,

0 in this case, every second the state of the output buses of the adder increases by two units.

If then uniform motion occurs, then the optocouplers 4 are above zero

5 column and at the second input of the adder 10 along all lines there are logical zeros. The output state of the adder does not change. In this case, the adder 10 starts to work on subtraction. The adder 11 and the register 9 work similarly.
