DEVICE FOR AUTONOMOUS MEASUREMENT OF PHYSICAL QUANTITIES Russian patent published in 1997 - IPC

FIELD: measurement technology, design of measurement system for robot sensing functioning independently of man. SUBSTANCE: device for autonomous measurement of physical quantities has two units 1 and 2 of measurement converters connected correspondingly to first and second inputs of first 3 and second 4 controlled commutators, comparator 5, which direct input is connected to output of first unit 1 of measurement converters and which inverse input - to output of second unit 2 of measurement converters. Output of comparator 5 is one of outputs of device and is directly connected to controlling input of commutator 3 and via inverter 6 - to controlling input of commutator 4 which output is linked to input of divider 7 having N outputs and manufactured in the form of resistive matrix. Device also has N groups each incorporating adder 8, comparator 9, controlled commutator 10. In last group there is no controlled commutator. Output of adder 8 of each group is connected to inverse to input of corresponding comparator 9 and first input of commutator 10 with exception of last group where commutator is absent. Outputs of comparators 9 are outputs of device and are connected to controlling inputs of corresponding commutators 10. Output of commutator 10 of each preceding group is connected to first input of adder of following group and to second input of commutator 10 of mentioned group with exception of last group. First input of adder 8 of first group is connected to zero bus and second input of commutator 10 of first group. Second inputs of adders 8 are connected to proper outputs of divider 7 manufactured in the form of resistive matrix and direct inputs of comparators 9 of groups are connected to input of first commutator 3. EFFECT: enhanced functional efficiency and reliability of device. 1 dwg
