FIELD: electricity.
SUBSTANCE: system contains terminal data collection and transmission units (DCTU), operating on different frequencies within chosen operating band, measuring devices and central DCTU. Every terminal DCTU contains microcontroller and interface block. Central DCTU contains the second interface block, analog-to-digital converter and external interface unit. Every terminal DCTU contains pulse hopping signal shaper generating randomly varying carrier frequency. Central DCTU contains pulse hopping signal processing module.
EFFECT: higher range, noise immunity and reliability due to implementation frequency hopping technology.
