The disadvantage of such devices lies in the formation of false output signals when short-term signals from sensors appear.

The closest to the proposed solution of the technical problem is the driver of the signals about the maximum deviations of the parameters of the object, which is part of the systole of the remote control and control, which contains sensors for switching off the electric | protection of consumers of electricity, the element OR, and the number of sensors triggers, HH vertori, elements AND, single vibrators, and differentiating RC circuits Gz.

The disadvantage of this shaper. is the ability to form them

The goal is achieved by the fact that the driver that contains the sensors of the object parameters, the time relay and the number of sensors are logic elements AND, the first inputs of which are connected to the outputs of the sensors, and triggers with two stable states, which are connected to the direct outputs The inputs of the corresponding elements are AND, 1 {the information inputs of which are connected to the outputs of the sensors, and the outputs through the element OR are connected to the input of a time relay, the output of which is connected to the second inputs of the elements AND, additionally contains 0 .Inv The actuators are based on the number of sensors, the inputs of which are connected to the corresponding outputs of the sensors and the latter. the inputs of the elements are And, the outputs of which are connected to the zero inputs of the trigger with two stable states, and the single inputs of the triggers are connected to the outputs of the corresponding elec- tromes I. The drawing is a functional on the block diagram; shaper signal p of maximum deviations of object parameters. It contains sensors 1 maximum deviations of the object parameters, element 2 OR, relay 3 times, and according to the number of SENSORS 1 triggers 4 with two stable states, inverters 5, elements b and 7 I. The delay for the operation of the relay 3 times is selected by one. above the maximum duration of the false false signals of sensors 1, and the delay for releasing the time relay 3 is determined by the required duration of the output signal of the device. The output of each sensor 1 is connected to one input of the corresponding element bI, with an information code input of element 7I and through an inverter 5 with zero input of the corresponding trigger 4, whose single input is connected to the output of element bI, the output of trigger 4 with two stable states connected to the control input of the element 7 I. The outputs of the elements 7 and through the element 2 OR are connected to the input of the relay 3 time, the output of which is connected to the output terminal 8 of the device and connected between the other inputs of the elements 6 and the driver dy r1tsim manner. In the initial state, the signals of sensors 1 are absent and the output signals of the inverters 5 trigger 4 are set to the zero position. In the case of the maximum deviation of the object's parameter, the output signal of sensor I is fed to one input of the element bI and through the series-connected elements 7 I and element 2 of the W) to the 3xoh relay 3 times. If the duration of sensor signal 1 is greater than & When the relay is triggered by the relay 3 sp & le, the relay 3 times is triggered and outputs a signal to the inputs of the AND components and to the output 8 of the signal conditioner on the maximum deviations of the parametrosis of the object. the insufficient signal duration of sensor 1 of relay 3 does not turn on, and the signal to the output stamp 8 does not pass. When a relay 3 triggers, its input signal passes to the input terminal 8 and through element 6 I, 1 on one input of which sensor 1 signal is present, sets trigger 4 to one position, the output signal of which prevents the signal from sensor 1 through element 7 I to input a time relay 3, whereby the signal at the output terminal 8 of the device is removed. Thus, in case of occurrence of an emergency parameter deviation by -. the output terminal 8 of the device forms a pulse, the duration of which is determined by holding the release of the relay 3 times. After the completion of the change in state of the trigger 4, the device is ready for the formation of a pulse of the maximum deviation of the next parameter of the object. The proposed implementation of the device eliminates the possibility of generating spurious output signals when 1 | the appearance of short-term signals from sensors caused, for example, by voltage fluctuations in the power supply network, etc. The invention formula Signal shaper about the maximum deviations of the object parameters containing the object parameters sensors , time relays and by the number of sensors, the logic elements are And, the first inputs of which are connected to the outputs of the sensors, and triggers with two resistances, to the direct outputs of which are connected The control inputs of the corresponding elements AND, whose information inputs are connected to the sensor outputs, and the outputs through the IS1 element are connected to the time relay input, the output of which is connected to the second inputs of the elements and, in order to expand its use, the hedgehog contains inverters according to the number of sensors whose inputs are connected with the corresponding. sensor outputs and VTO1SHMI elements and outputs whose outputs are connected to zero trigger inputs with two stable states, and single trigger inputs are connected to the outputs of the corresponding elements I.
