(54) LOGICAL SECURITY ELEMENT

one

The invention relates to automation and computing and can be used in the construction of various control circuits.

Known logic element auth. St. No. 459856, which consists of two series-connected integrators connected to the output buses of the signal sensors and two comparison circuits with zero level; the outputs of which are connected to the output buses of the control unit of the actuator, the output of the second integrator is connected to the input of the first and one of the comparison circuits with a zero level, and the output of the first integrator is connected to the input of another comparison circuit with a zero level. object only in the vicinity of the origin.

The purpose of the additional invention is to expand the functional capabilities of the logical element.

This target is achieved by introducing into the logic element a set of settings for specified levels, the outputs of which are connected to other inputs of the comparison circuits.

As a result, it is possible to translate the phase object dimensions of an object into any admissible given neighborhood of the phase space and reduce the accuracy requirements for approximating functions; integrators.

The logic element consists of series-connected integrators and 2, connected to the output buses of dagchikov 3 and 4 signal 3 - 9 signals and two circuits 5 and 6 comparing with a given "level. The output of the integrator 2 is connected to the input of the integrator I and simultaneously with one of the inputs of the 6-comparison circuit with the specified VDOBnen. The output of the integrator 1 is connected to one of the inputs of the comparison circuit 5 with the specified level. The outputs of the comparison circuits 5 and 6 are connected to the output buses 7 and 8 of the control unit. The set levels for the circuits 5 and 6 of the comparison are set by the block 9 of the settings, the outputs of which are connected to other inputs of the circuits. 5 and 6. The logic element works as follows. For example, it is required to translate an object from point 10 to point 12 with coordinates (a, b) of the phase space. A signal X is generated at the output of integrator 1, and a signal X is output at integrator 2 output. For the integrators to work, they assume the assumed control opposite to the X sign. that the object should choose the control sign opposite to the expected one. At point 11 the phase trajectory will cross line A, which corresponds to the signal End of Analysis. - This signal can be used to switch the control sign on the object. The value of a-and dl for the object, and, for example, i and is equal to - «-. Thus, in order to transfer the object to point 12 (a, b), it is necessary to submit a setpoint (E-A) to the comparison circuit 6. The invention of the logical element of the author. St. No. 459856, characterized in that in order to extend the functionality thereof. A set of settings for specified levels has been entered, the outputs of which are connected to other inputs of the comparison circuits. Sources of information accepted.
