Abstract

The invention solves the problem of cascading programmable logic arrays for controlling automata in ceramic production to create combinational logic circuits in cases where it is necessary to expand the number of inputs, the number of outputs and the number of termi. Signals from the controlled technological process are fed to the inputs of two programmable logic arrays, while their outputs are fed to the inputs of another pair of programmable logic arrays. The output from the second pair of programmable logic arrays is fed to the input of another pair of these circuits. The outputs from the third pair of programmable logic arrays are already control signals for the actuators of the given technological process.

Description

The present invention relates to the capability of programmable logic arrays for controlling automata in a ceramics industry, which is composed of programmable logic arrays such as. elements and very large integration to create combinational logic circuits.

The prior art is such that a programmable logic field can be used to design and implement combinational and sequence circuits. Each type of programmable logic '' field can be connected with a certain number of inputs, create a certain number of their logical sums, and output a certain number of output functions, that is, sums of logical sums. Doposis' known solutions have not dealt with the complex case if the number of inputs, outputs, and terms is insufficient. Insufficient number of inputs, outputs and term can be solved by one programmable logic pole in certain cases, which allows manufacturing of integrated circuit technology, but this solution is economically advantageous if the proposed programmable logic field is produced in a large series of tens of thousands of pieces.

The above mentioned drawbacks are eliminated by cascading the connection of programmable logic arrays for the control of automatic machines in ceramic production, which is composed of programmable logic arrays as elements with very large integration to create combinational logic circuits according to the invention, which is based on to the inputs of the first and second programmable logic poles. The outputs of the first and second programmable logic terminals are connected to the inputs of the third and fourth programmable logic terminals. The outputs of the third and fourth programmable logic poles are connected to the inputs of the fifth and sixth programmable logic poles. The outputs of the fifth and sixth programmable logic poles are inputs for the actuators of the controlled technological process.

The cascading connection of programmable logic arrays for control of automata * in ceramic manufacturing enables the creation of combinational logic circuits to control the RF automata where the number of inputs, the number of terms and the number of outputs is insufficient and where it is technically not possible to realize the control circuit with one programmable logic field.

The attached drawing is a block diagram of a cascade wiring of programmable logic arrays for the control of automatic machines in ceramic production. The outputs of the process control position sensors are connected to inputs 1, 2, J of the first and second programmable logic poles 101 and 102. The outputs 5, 6, 2, 8 of the first and second programmable logic poles 101 and 102 are connected to inputs 2, i2i. il, 12 of the third and fourth programmable logic poles 103 and 104. The outputs 13, 14, 15, 16 of the third and fourth programmable poles 103 and 104 are connected to inputs 12, 16, 12, 20 of the fifth and sixth programmable logic poles 105, and 106. The outputs 21, 22, 23, 24 of the fifth and sixth programmable logic poles 105 and 106 are for control signals, i.e. inputs for the actuators of the controlled technology process. An increase in the number of inputs allows blocking of the programmable logic fields 101 and 102 as shown. The expansion of the number of terms allows blocking of the programmable logic fields 103 and 104 as shown. The expansion of the number of outputs allows blocking of the programmable logic fields 105 and 106.

In the case of realization of cascading of programmable logic arrays according to the invention, it is necessary to use the train as 6 programmable logic arrays, according to the control function for the given machine, by combining eg outputs J to J and merging outputs 13 to 16. one to two and sometimes more programmable logic arrays can be used.
