Description

The sensor unit 1 is designed to generate signals about the movement of a moving object. Sensors 6ij are designed to select a monitored moving object from a variety of objects and generate signals about its passage through the exits ij of the nodes of the transport network on which the sensors are located. Selection of a mobile facility with a large carrying capacity from a variety of circulating rolling stock and a railway transport network can be carried out, for example, using strain gauges mounted on specific pressure of wheelsets of an object mounted on rails at the entrance arrows of the station nodes.

The encoders of rows 2 and columns 3 at the inputs (where m is the number of edges of the transport network graph) and n outputs are each intended to form signals at the outputs 1. .. when signals at the inputs 1 ... N from the 6IJ sensors come with the first () , and the second (.p) indices of rows and columns of the transport network matrix, respectively.

Unit 4 is designed to convert the sensor signals according to the algorithm shown in FIG. 1 in the table. 1. In the first line of the table. 1, defining the algorithm, the designations of the initial positions or directions of movement of the object are given, in the second line - the designations of the sensors from which signals are received, in the third line - the results of the conversion of sensor signals, which are the designations of the resulting positions (II, jj) or directions of movement ij, ji) of the object for the four transform variants in rows and columns of the transport network matrix.

Unit 5 is designed to graphically display the movement of an object on a map of the transport network. Indicators 7 II are located with reference to the designation of nodes of the transport network and are intended to indicate the location of the object in these nodes, indicators Tij (Mj) are placed on the map with reference to the outputs of the nodes of the transport network and are indicated by the arrow .

FIG. Figure 1 shows an example of an indication of the movement of an object along a predetermined route indicated against the background of the sensor unit 1. At its initial state (indicated by a triangle) at an instant, the object is at point (node) 1 of the transport network. Further movement of the object is indicated by a dash-dotted line. The indication state of the object moving to

moments after the issuance of the sensor signals are given in Table. 2

Matrix 4 contains n2 signal processing nodes 8ij (i, 1, p) located in nodes

matrices of the php dimension; nodes 8 ij have common inputs 9 for setting the initial state of the device. Nodes 8 Each of the 1st () rows and each j-ro) column of the matrix have common inputs 10, 11, respectively. In addition, nodes 8II (have groups of inputs 12, 13, nodes 8 Ij (i ,, n, t / j) have outputs 14, 15 connected to one of the inputs 12.13 of the group, respectively, node 811 common with the node eij-line matrix and output

5 16 connected to one of the inputs 12 of the 8jJ node group in common with the 8IJ node of the column, matrix. The nodes 8lj (8ji) also have inputs 17, 18 and outputs 19, 20, while the inputs 17 of the blocks 8lj, 8jl (,, n, (connected to

0 outputs 19, and inputs 18. - outputs 20 nodes 8JI, 8ij, respectively.

Nodes .811, 8ij contain triggers T 21 and elements AND 22 with inputs 10, 11, element AND 23, elements OR 24, 25, and delay elements 26. 27. Delay elements serve to delay signals during triggers and switching triggers schemes. VseaSij contains, besides the element And 22 and the trigger 21, the elements And 28. 29,

0 30, delay elements 31,32, serving to delay the signals at the time of transients in the circuits.

The device works as follows.

5 After a general reset of the device, carried out by applying a signal of sufficient length to input 9, it is set to state 1 by applying a signal to the single input of trigger 21 of the Qii node

0 or 8IJ corresponding to the source location of the object at the node H or the direction of movement of the object ij in the transport network. Timing diagram of the device for the initial state 1 trigger 21

5 of node 81}, in which the indicator 7ij of block 5 is lit, is shown in FIG. 5. At the time t4 of the movement of the object along the route shown in FIG. 1, the 6IJ sensor is triggered and outputs signals to the encoder inputs

0 rows 2 and column encoder 3. Signals from the 6IJ sensor received at the encoder inputs form signals at the i-th output of the encoder 2 and the j-th output of the encoder 3, which arrive at the buses of the 1st row and jrro

5 columns of matrix 4. When a signal arrives at the inputs 10, 11 of node 8ij, element AND 22 is triggered. When element 22 triggers, element 28 also triggers, input 17 of which contains backwater from the inverse output of trigger 21 of node 8 ij, and element

And 29. The signal from the output of the element And 28 enters the counting input of the trigger 21 of the node 8IJ and translates it to the state O, and the indicator 7ij goes out. At the same time, the signal from the output of the element 29 through the output 14 of the node 8iJ enters one of the inputs 12 of the group of the node 8il and through the element OR 24 of this node transfers the trigger 21 of the node 8M to the state 1, and the indicator 7I of the unit 5 lights up. as shown in FIG. 5, the signal at the outputs of the delay elements 31, 32 of the node 8IJ and 27 of the node 8I changes in accordance with the change in the state of the triggers of these nodes. In this case, the device operation cycle is completed. At time 15, the 6IJ sensor is again triggered, the signals from which are sent through the encoder 2, 3 to the inputs of matrix 4. In the same way (as in the previous cycle), elements And 28, 29 of node 8ij are activated. The signal from the output of the And 28 element triggers the 21 trigger of the 8IJ node to state 1, and the indicator 7ij of the block 5 lights up. At the same time, the signal from the output of the And 28 element through the 15 output of the 8ij node enters input 13 of the 8IJ node and through the OR 25 element, the AND element 23, the first input of which is supported from the direct output of flip-flop 21 of node 8ii, enters the input of delay element 26. After a delay time Tc, the pulse from the output of element 26 sets the flip-flop 21 of node 8ii to state O, and indicator 7ii goes out. At the same time, the signal at the outputs of elements 31, 32 of node 8ij changes. Through time Tz after the transition of the trigger 21 of the block 8II to the state O, the signal at the output of the delay element 27 of this node changes, after which the device is ready for the next cycle of operation. After the sensor 6 JI has triggered at time te, an element is triggered. And there are 22 nodes 8 ji, from the output of which the signal goes through the output 20 of the node 8ji to the input 18 of the node 8ij. When a signal arrives at input 18, element 30 is triggered, at the first input of which there is backwater from the direct output of flip-flop 21 of node 8ij. The signal from the output of the AND element 30 is switched to the state O of the trigger 21 of the node 8ij, while the indicator 7ij goes out and the output 16 of this node enters the input 12 of the node 8jj. The signal received at input 12 of node 8jj, through element OR 24, sets the trigger 21 of this node to state 1, and indicator 7jj lights up. After a delay time Tc, the signal at the outputs of elements 31, 32 of node 8ij and element 27 of node 8jj changes. Transients in the device in this cycle are completed. The last of the device operation cycles is as follows. At time t, sensor 6 is triggered and outputs signals to encoders 2, 3. On output signals, the encryptorop element AND 22 of node 8ji is triggered. And the signal from the output of this element triggers AND element 28, at input 17 of which there is support from output 19 of node 8IJ. The signal from the output of the AND element 28 arriving at the counting input of the trigger 21 of the 8JI node transfers the trigger to the state 1 (the indicator turns on 10 Kator7 1) and through the output 15 enters the input 13 of the 8jJ node. The signal received at the input 13 of the group of the node 8jj, through the element OR 25 occurs on; the input element And 23, on the first input of which there is a backwater from the direct

5 trigger outputs 21 of this node. Element And 23 is triggered and outputs a signal to delay element 26. After time Tz, the signal from the output of element 26 sets in O the trigger 21 of the node 8jj, and the indicator 7jj goes out. AT

0 the same instant of time changes the signals at the outputs of the delay elements 31, 32 of block 8jj. Through time Tz after being transferred to the state O of the trigger 21, the signal at the output of the element 27 changes - the operation cycle

5 device is complete.
