Description

one

The proposed device relates to the field of automation and computer technology and is intended for addressing moving objects of continuous transport installations without address carriers on moving objects.

A device for addressing moving objects is known, which contains a memory matrix, the inputs of which are connected to the outputs of the distributor, the launch bus of which is connected to the first output of the command circuit, two inputs of which are connected to the object position sensors, and the second output through the trigger - to the distributor memory matrices through the address information output element — with the third input of the command circuit.

The aim of the invention is to increase the speed of the addressing device in the testing mode of the output sensor program while maintaining the positive properties of the prototype.

The proposed device differs from the known one in that the distributor is reversible, the reverse bus of which is connected to the second output of the command circuit, the third input of which is connected to the output of the memory matrix through the information advancement control element.

The drawing shows a block diagram of the proposed device.

It contains the memory matrix /, bus (input) 2 input address information into the memory matrix, wi y (exit) 3 output address information (output) from the memory matrix,

reversible pulse distributor 4; bus 5 read by the elements of the distributor cells of the memory matrix, the element 6 controls the advancement of address information along the memory matrix, the command circuit 7, bus 8

launch of the distributor, bus for receiving the signal. Advance of address information by the command circuit (third input 9 of the command circuit), bus 10 of the reverse of the distributor, sensor 11 of the input of the moving object to the area; sensor

12. the output of the movable object from the site and the generator of clock pulses 13.

The arrows indicate the directions of movement of the address information along the memory matrix and the signal along the distributor.

The basis of the device is formed by a memory array 1, constructed for example in the form of a shift register. The number of cells in the matrix is equal to or greater than the possible number of moving objects in a controlled area of the transport installation. The address of the moving object is recorded in the matrix cells as a binary code. Each cell is a set of memory elements, e.g. ferrite transistor modules, a number. elements in the cell are determined by the number of binary bits of the address code. Accepts the address information of the incoming load but input 2 is the input cell of the matrix, and the output code of the output load is removed from output 3 of the output cell.

Promotion of the address information in the matrix is carried out by means of a reverse distributor of pulses 4. For each cell of the matrix of nodes and read imulses of the distributor elements.

The outputs of all the cells of the matrix to us through element 6, which controls the promotion of address information, are nodans to the input 9 of the command scheme 7.

The proposed device works as follows.

By the command of the sensor 13 of the entrance of the movable volume, the address information stored in the memory matrix is shifted by one cell to the output. For this, the command circuit 7 sends a trigger signal to the bus 8. Under the influence of the advancing pulses from the clock pulse generator 13, the signal moves along the distributor in the direction coinciding with the upper arrow of the distributor 4. In this case, the memory matrix cells are alternately directed from the output to the input . After the input cell is released, the address code of the incoming load is accepted.

Upon command of sensor 12, the address code stored first to the output of the memory array is searched for and output. For this, the command circuit 7 sends the distributor start signal to the bus 5, the distributor signals alternately in the direction from the output to the input will read the cells of the memory array.

As soon as the signal of the distributor reads the cell containing the address code, the element 6 of the control of the advancement of the address information will work and will give a signal to the input 9

command schema. Last bus 10 switches the valve to reverse (bottom arrow in valve 4). Thus, the signal of the distributor, reading the memory cell in the direction from the input of the matrices to the output, will display on the tires 5 the address information of the released load.

The command circuit controls the order in which the sensor program is processed. When two commands are received at the same time, the program of one and then the other sensors is first processed.

The clock generator does not enter directly into this device, it serves all the addressing devices of the transport system.

The proposed device can serve as a basis for achieving the addressing of moving objects of any continuous transnort systems.
