Abstract: FIELD: control systems. 
     SUBSTANCE: invention relates to automated control systems (ACS) and can be used in ACS construction complex, which includes geodesic dispatching station, house building factory for production of building modules, blocks and materials, a construction site for erecting multi-storey buildings and structures and a system for receiving and transmitting information and can be used to make rapid and reasonable decisions at all levels of control and control of loading and unloading and transport and storage processes using computer equipment and radio frequency labels. ACS construction complex comprises dispatcher geodetic point 1, house building factory 2 for production of building modules, blocks and materials, warehouses of building modules, blocks and materials, construction site 4, loaders 5.i (i = 1, 2, …, n), trailers 6.j (j = 1, 2, …, m), devices 7.1 (i = 1, 2, …, I) for control of robotic technological complexes and information receiving and transmission system (IRT) 8. Duplex radio station placed in dispatcher geodetic station 1 comprises computer 9, first master oscillator 10, discrete message source 11, first phase manipulator 12, continuous message source 13, amplitude modulator 14, first heterodyne 15, first mixer 16, second heterodyne 17, first amplifier 18 of first intermediate frequency, first power amplifier 19, first duplexer 20, transceiving antenna 21, a second power amplifier 22, second mixer 23, first amplifier 24 of a second intermediate frequency, a first limiter amplifier 25, a first synchronous detector 26, first multiplier 27, a first band-pass filter 28, a first phase detector 29, first recording unit 30, first amplifier 87 of total frequency, first amplitude detector 88 and second switch 89. Transmitting radio station placed in dispatcher geodetic station 1 comprises device 33 of differential corrections, second master oscillator 34, second phase manipulator 35, third power amplifier 36, transmitting antenna 37, GPS signal receiver 32 with antenna 31. Duplex radio station placed on each loader (trailer) comprises sensor 38 of loader (trailer) number, sensor 39 of loading-unloading, microprocessor 40, third driving oscillator 41, third phase manipulator 42, second amplitude modulator 43, third heterodyne 44, third mixer 45, fourth heterodyne 46, second amplifier 47 of the second intermediate frequency, fourth power amplifier 48, second duplexer 49, second transceiving antenna 50, fifth power amplifier 51, fourth mixer 52, second amplifier 53 of first intermediate frequency, second amplifier-limiter 54, second synchronous detector 55, second multiplier 56, second band-pass filter 57, second phase detector 58, second receiving antenna 59, high-frequency amplifier 60, first delay line 61, third phase detector 62, loader (trailer) location unit 63, third receiving antenna 64, second receiver 65, sixth power amplifier 66, third detector 67, third transceiving antenna 68, seventh power amplifier 69, fourth phase detector 70, correlator 71, threshold unit 72, light beacon 73, sound beacon 74, second registration unit 75, switch 76, second delay line 77, adder 78, synthesizer 93 of carrier frequencies and logic element 94. Each radio-frequency label comprises piezocrystal 79.i, transceiving antenna 80.i, electrodes 81.i, buses 82.i and 83.i, set of reflectors 84.1, unit 95.i accessibility to IDT, narrow-band filter 96.i, amplitude detector 97.i, keys 98.i and 99.i (i = 1, 2 …, n). As a result, higher reliability of ACS is provided on the basis of higher reliability of reading individual codes simultaneously from several units (modules) located in the zone of radio sounding, by successive in time of their radio query. 
     EFFECT: higher reliability.
