The invention relates to automation, in particular, to devices for controlling moving objects of an ACS, and can be used in constructing an ACS.

The purpose of the invention is to increase the accuracy of information transfer.

The drawing shows the functional diagram of the device.

The device contains the first 1, second 2 and third 3 registers, the first 4 and second 5 decoders, block 6 of memory, counter 7, generator 8 of time pulses, element 9, group of elements 10, -10t, first and second groups of blocks of elements And 11, -11n, U 12, -: 12П group of blocks of elements OR 13, - 13П, first 14, second 15, third 16 and fourth 17 delay elements, trigger 18, first 19 and second 20 groups of device inputs, synchronous input 21 and a clock input 22 of the device, a group of outputs 23, -23 „and an output 24 of the device.

The device works as follows.

To control the moving objects, the information inputs 19 of the register 1 receive a code representing the number of the moving object and the indication of the call of the moving object to the communication. At the same time, an information message arrives at the information inputs 20 of register 2, which must be transmitted to the mobile object. Information from the inputs 19 and 20 to the registers 1 and 2 is entered using the sync pulse input from the input 21 to the corresponding synchronous inputs of the specified registers.

Before the operation of the device, all nodes and blocks are reset to the initial state (initial reset circuits are not shown).

The decoder 4 decodes the code of the object number and at one of its outputs generates a high potential, which opens one of the inputs respectively (L

branch element And 10; For example, element 10. And then the sync pulse from input 21, delayed by element 16 for the response times of register 1 and decoder 4, passes to the input of the fixed memory cell of block 6, where the reference coordinates of the moving object, characterizing the coordinates of the start point, are stored. movable object from which he began his movement on a given route. Codes of coordinates from the output of block 6 by a synchronization pulse from the output of delay element 17 are written to register 3.

A feature of register 3 is that its most significant bits are connected according to the counter circuit, the counting input of which is connected to the clock input 22 of the device, to which the clock pulses of time are applied.

The frequency of the pulses of time is determined by the selected time interval. For example, for a period of 1 hour, the number of bits in a register can be allotted to five, and every 24 hours the five most significant bits of the register will overflow and reset to zero.

Thus, the address code of the channel by which the mobile object with the specified number will be called consists of the base address code received from the corresponding cell of block 6 and the code determined by the state of the high bits of the register operating in the counter mode. The decoder 5 decodes this code and high potential corresponding to the code in register 3, opens the corresponding blocks of elements And the first and second groups. Suppose that these blocks of AND elements are blocks of AND 11 and 12 elements.

Then the pulse from the output of the delay element 17, the delayed element 15 at the time of reading and writing the code to the register 3, arriving at the second input of the block of elements 11, the contents of the indicative part of register 1 is copied through the blocks of elements 11 and OR 13 the data channel that is currently connected to the moving object via a coarse data channel. At the same time, the pulse from the output of the delay element 15 is fed to the single input of the trigger 18 and sets it to the single state

at which the trigger 18 with a high potential from the direct output of the output opens element 9 and thus connects the output of the generator 8 to the counting input of the counter 7. 23 will reach the mobile object via an omnidirectional antenna, and the mobile object lifts the directional antenna of the exact channel to receive the information message.

After this time has elapsed, a pulse appears at the transfer output of counter 7, which, through the block of elements And 12, rewrites the code of the information message from the output of register 2 through the block of elements OR 13, to output 23,. This code is received by the mobile unit for execution through a directional antenna of the exact channel. At the same time, output 24 is signaled to the control point that a control command has been issued to the output of the device. The same pulse from the transfer output of the counter 7, which is delayed by the time of the transmission of the information message by the delay element 14, arrives at the inputs Reset of the registers and sets them to the initial state.

The device is ready for a new work cycle.
