Abstract

The invention relates to the transmission of information from a vehicle and can be used for the operational control of the operation of rail transport. The purpose of the invention is to increase credibility.

At the moment when the first railway wheel 1 passes through the readout section, a signal is emitted from the sensor 6 signal, through which sensors 4 are connected and information is recorded from the 1st to 9th bits of the buffer register. At the moment when the first wheel passes the second control zone, the second railway wheel 1 of the vehicle hits sensor 6, the signal from which goes to the second group of inputs of the buffer register and is recorded into the 10th to 18th bits of the buffer register from the first and second wheels of the vehicle first and second control zones. 2 n. i. y (L with HS about oo fi. 7

Description

The invention relates to the transmission of information from a vehicle and can be used for the operational control and management of railway transport in the mining, chemical industries, ferrous and non-ferrous metallurgy, in enterprises of other industries where railway transport is used.

The purpose of the invention is to increase reliability.

FIG. 1 shows the structural diagram of the device; in fig. 2 - functional device diagram.

The railway wheel 1 (Fig. D), on which magnetic tags 2 are applied, moves along the surface of the rail head 3, to the side surface of which the readings 4 elements of the first control zone are attached, readings 5 elements of the second control zone and the sensors 6 of the wheel.

Element 4 of the first control zone and element 5 of the second control zone are connected respectively to the inputs of one and another sensor switches 7 of the first and second control zones, which are connected to the first and second control zones of the first and second control zones connected to the decoder inputs by the first and second groups of outputs 9 of the first and second control zones, which OHO; D, you are connected to the inputs of the information processing unit 10. The first output control unit 11 is connected to the fault inputs of the buffer registers 8 and the switches 7.

The device works as follows.

Before the vehicle enters the readout zone, the switches 7 are in the initial state.

When a first wheel of a vehicle with a two-axle carriage comes to the reading section, the control unit 11 sends a signal to the control input of one switch 27, the signal to which one switch 7 node-1; 1 connects the sensors 4 to the first group of inputs of the buffer register 8 first control zone) 1. Therefore, when the first wheel passes through the first control zone, the signals of the elements 4 are recorded respectively in 1-9 bits of the buffer register 8.

At the moment when the first wheel passes the second control zone, the second wheel of the vehicle hits the sensor 6, the signal of which arrives at block 11. Block 11 outputs a signal to the switch 7, through which the outputs of elements 5 are connected to the second group of inputs of the buffer register 8 of the second control zone. Therefore, when the second wheel passes the first control zone, the cells} of the elements 4 are written respectively to the 1-9th bits of the buffer register 8. At the same time, the elements 5 of the second control zone read magnetic labels from

0

first wheel. Moreover, the signals of the elements 5 are recorded respectively in the 10-18th position of the buffer register 8 of the first control zone.

After the first code passes the second control zone at the time it travels to the sensor 6, the block 11, on the basis of the signal from the sensor 6, outputs to the control input of the switch 7 a signal that connects the outputs of the elements 5 to the first group of inputs of the buffer register 8 of the second control zone. Therefore, when the second wheel passes the second control zone, the signals of the elements 5 are recorded respectively in the 10-18th digit of the register 8.

5 Thus, the information read from the first wheel of the vehicle is written to the buffer register 8 first, and the information read from the second wheel to the buffer register 8 of the second control zone. The information at the outputs of one and the other decoder 9 appears, depending on the position of the 8 signals read from the first (second) wheel in the buffer registers. So that the readable magnetic mark is not perceived as two bits by

2, the signal recorded in the first bit of the first six bits of register 8 is prohibited from passing to the first output of the decoder 9 signals recorded in the fifth and sixth bits of the first six bits of the buffer register 8.

0 After the second wheel passes the read section at the moment of its arrival on sensor 6, unit 11 outputs a reset signal to switches 7 and buffer registers 8 and returns them to their initial state.
