(54) DEVICE FOR READING INFORMATION FROM VEHICLE

(57) The invention relates to railway automation and can be used in the systems of interval control of the movement of trains. The purpose of the invention is to increase credibility. Code plate 2 with mirrors mounted on the locomotive. The radiation receivers 3 perceive the light reflected from the code plate 1 and output information to the first and second registers 6 and 7. The decoding of the plate code is carried out by the element AND 8 and the element OR-NOT 9, which give permission to overwrite the information in the third register 11. Setting the registers reset is performed by reset unit 12. 2 Il.

The invention relates to railway automation and can be used in the systems of interval control of the movement of trains.

The purpose of the invention is to increase the reliability

FIG. 1 shows a mask for a reflector of a code plate, which may be located on a locomotive for transmitting information to a stationary device or on a route for transmitting information to a locomotive; in fig. 2 - schematic diagram.

The device contains sources 1 light, through code plate 2 connected to receivers 3, to which the pulse shapers 4 are connected, through amplifiers 5 connected to the pee and second registers b and 7, whose outputs through element I8, element OR NOT 9 are connected to the inputs of the elements 10. The output of the element 10 is connected to the counting input of the third register 11. The reset unit 12 is connected to the installation inputs of the first 6, second 7 and third 11 registers.

The device works as follows.

Code plate 2 is mounted on the outer side of the locomotive in front of the sources 1 and alternately pass mirrors (not disguised parts of the common mirror). Moreover, the mirrors on the ground have a strictly fixed arrangement and are the key to the opening of the device (control mirrors). Any other combination of the location of the mirrors at the indicated coordinates prevents the device from opening and receiving the signal. The setting is defined by items 8 and 9.

The mirrors of the second (middle) row are smaller and provide for clocking of the circuit operation. The smaller size of the mirrors of the second row ensures that the information of other rows is perceived only when the mirrors of these rows are located in the center of the optical axis of the corresponding optical axes (gating principle). Moving the mirrors of the second row provides the clock pulses to the counting inputs of the first and second registers 6 and 7. At the same time, the first and second registers of 6 m 7 receive information on similar channels. Since the registers mentioned are shifted to the right, the incoming information is recorded in a cell with a lower number, and then the new information (0 or 1) is shifted into a cell with a larger number. After passing all the columns of mirrors in front of the receiver at the outputs of the first and second registers 6 and 7, the information corresponds to that recorded in the masks of the first and third rows. That is, the presence of a mirror with a coordinate of 0.1 corresponds to the state of the first output of the first register b (output 1), the absence of a mirror with the coordinate 1.1 corresponds to the state of the second output (output O) of the same register, etc. If after the passage of the locomotive at the first and last outputs of the first register 6 and the second and penultimate outputs of the second register 7 there are logical 1, e at the second and penultimate outputs of the first register b vt the first and last outputs of the second register 7 are logical O, then at the output of element 10 Appears 1, which initiates the recording of information from the information outputs of the first and second registers 6 and 7 into the third register 11. The outputs of the third register 11 are set in full accordance with the mirrors located at coordinates 2.1; 3.1; 4.1; 5.1; 2.3; 3.3; 4.3; 5.3. The received signal can carry information about the number of cars, the weight of the train, etc., and can be used in the IRDP system. After this information is received by the TIR system, the reset device 12 resets the aux registers.

The proposed device can transmit information to the rolling stock about the length of the block, plan and profile of the path, etc.
