FIELD: radio engineering, communication.
SUBSTANCE: communication system for collecting data has a distributed network for delivering data to a query initiator device, wherein the distributed network has a plurality of devices for reading parameter values of at least one sensor, a control processor assigned by the query initiator from a number of reading devices, designed to query a plurality of reading devices, wherein the control processor is configured to transmit to the distributed network query commands for a time which overlaps the wakeup period of the reading devices, having an arbitrary wakeup time, receive sensor data, sample said data according to priority and send acknowledgement to the selected reading device, in case of collision, sending negative acknowledgement; the reading devices are designed to receive query commands, transmit data, termination thereof upon receiving acknowledgement, and terminating data transmission upon receiving negative acknowledgement, and resumption thereof after a pseudorandom delay.
EFFECT: high coefficient of utilisation of capacity and reduced power consumption and shorter data collection time.
