Description

" one

The invention relates to automation and computing and can be used to control various devices according to a given program.

The purpose of the invention is to expand the scope.

The drawing shows a block diagram of the device pantaline.

The device contains a generator of 1 pulses, the first 2 and the second 3 counters, the memory block 4, the registers 5, the first elements And 6, the second 7 and the third 8 elements I.

The memory unit 4 stores not only the service program of both points and objects, but also the time of their service. Memory block 4 is divided into section heads. Outputs that determine the division ratio of the first section of block 4 are connected to the installation inputs of counter 2. The number of information outputs of the second section of block 4 is equal to the maximum number of objects at one of the items “Elements And 6” are intended to form recording signals into registers 5,

The device works as follows.

The clock pulses of the generator 1 are fed to the subtracting input of counter 2, the pulse of transfer of counter 2 is fed to the inputs of elements 6-8, and the summing input of counter 3 "When a transfer pulse occurs, the whole device is shown.

In this case, registers 5 make a record of the new information present at their information inputs. Information is recorded only in the register 5 to which the element 6 is connected, which is open by the control of the third section of block 4. Thus.

information can be recorded not only in one register, but immediately into any, pre-programmed number of registers 5, containing

5 command control each item. If necessary according to the program, then the division factor 2 of the counter 2 changes. This is achieved by opening the element 7 with a pulse, each 0 stepping from the fourth section of block 4. The transfer pulse of counter 2, having passed element 7, makes the initial setting of counter 2 to the number coming from the first block sections 4.

If it is necessary according to the program, then the counter 3 is also zeroed out. For these purposes, the impulse coming from the fourth section of block 4 opens element 8. Thus, the programming of the coefficient of the counter of 3 pulses is achieved.

By momentum transfer counter

25 2 the counter 3 is triggered, which leads to the appearance of a new cell address of block 4, on the information outputs of which new information appears.

Thus, the proposed device allows not only the production of an arbitrary selection of objects and points of service, but also the time for their service, which greatly expands its scope.

The operating time range of the proposed software control device is determined by the formula

40 T tr Ki-Kj,

where t g - the period of the clock frequency of the generator;

K. is the division ratio of the 45 counter 2;

Ks - the division ratio of the counter and 3.
