FIELD: pulse equipment. SUBSTANCE: trigger, that keeps its state during power breaks, allows to increase resistance to interferences and trustworthiness of functioning, to simplify trigger operation control. Trigger, that keeps its state during power breaks, has four logic members, core with rectangular hysteresis loop and winding, resistor and integrating RC-circuit. First inputs of first and second gates are connected with output of third gate. Output of first gate through core winding is connected to input of integrating RC-circuit, output of which is connected with first input of third gate Middle point of core winding through resistor is connected with output of second gate, second input of which is connected with output of fourth gate. Second input of third gate is connected with second input of first gate and with reset bus, third input - with first input of fourth gate and with setting 1 bus, and fourth input - with interrogation bus and with second input of fourth gate, third input of which is connected with recovery bus. Second gate is made as difference gate and first, third and fourth gates - as negative-OR gates. EFFECT: increased resistance to interferences and trustworthiness of functioning, simplified trigger operation control. |
