SYSTEM OF COMMUNICATION AND DATA TRANSFER OF TOPOGRAPHIC SURVEY VEHICLE Russian patent published in 2012 - IPC H04B7/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio systems of data exchange. For this purpose a system is developed, comprising the following: a short-wave radio station (WRS) 1 carried onto a specialised vehicle, which is connected via data transfer equipment (DTE) 2 to a board computer (BC) 3 of an automated workplace (AWP) (not shown in drawings). The first inlet of the BC 3 is connected to a receiver of signals of navigation satellite systems (SR NSS) 4, the second inlet - to a control panel (CP) 5 of the AWP in the form of a BC 3 keyboard, and the outlet - to a video monitor (VM) 6 of the BC 3. The system of communication and data transfer is equipped with a carried short-wave radio station (WRS) 7, which along an information exchange channel via DTE 2 is connected to a control-correcting station (CCS) 8, an external radio facilities set (ERFS) 9 comprising two portable radio stations (PRS) 10 and an internal communication system (ICS) 11 in the form of a transport loudspeaker comprising two amplifiers of sound frequency (SFA) 12, two microphones (MC) 13 and four dynamic heads of a loudspeaker (LDH) 14. Antennas 15 are equipped with lifting mechanisms (LMA) 16 with an electric drive 17, arranged with the possibility of control from a single control panel (CP) 18. WRS 1 and 7 also include the following main units: a transceiver (TR) 19, an automatic matching device (AMD) 20, a remote control panel (RCP) 21, a modem (MD) 22.

EFFECT: development of an automated noise-protected data exchange between surface movable facilities and transfer of voice information inside them.
