Abstract

The invention relates to radio engineering and m. used for the detschiko's Omahic Interrogation polling, issuing on / off type information. The aim of the invention is to extend the functionality by transmitting to the communication line information about the state of the sensor, its identification, as well as starting 1 stop pulses. The device contains 1 clock pulse generator and demand nodes 3, each of which includes the OR 13 element, the shift register 12, the right 4 and Agora 5 AND elements, the 7 dimensional and the nine 9 triggers, and the link 15. The purpose of the invention is achieved by mixing down a 2-pulse divider, b also reporting on each polling node 3 of the signal converter 6, the first 10 and the second 8 NAND units, the coincidence block 11 and the switching block 14. 4 il.
