METHOD OF TRANSMITTING AND RECEIVING INFORMATION OF CONDITION OF STATIONS UNDER CONTROL AND TV SYSTEM FOR REALIZATION Russian patent published in 1994 - IPC

FIELD: telemetry. SUBSTANCE: general purpose command signal is transmitted in sequence from one control station to the other one. Time delay is chosen in such a manner that individual telemechanical communication is adjusted between control station and station under test. Series connection of telemetric equipment is provided by linear commutator 7 and time delay element 4 by means of general purpose command signal. Objects disposed in controlled station are controlled optionally. These objects are available for communication for that time. Control is performed by commutator 19 mounted in control station and other members of equipment. The method of command signal is used in the cycle of receiving number-pulse code which is formed by transmission of control signal from any station under control 2, as well as address of the station which is available for communication for that time period. The method concludes in sequence of operations when transmitting general and selection command control from control station to station under control. Then sequence of transmission of control annunciation signals is formed which is transmitted to control station from stations under control and addresses of objects of controlled stations are searched as well as sections of communication line to which they are connected. Telemetric communication is available with any stations connected with common communication line by using electric power supply which is disposed in control station only (additional communication lines are not used). Power supplies may also be used disposed on the objects. Open- or short-circuits may be found automatically in the communication line without introducing special equipment. System keeps its serviceability for any object which is connected to communication line in form of section of the line of controlled station where damage was detected. EFFECT: improved quality of control; wider volume of information to be transmitted. 2 cl, 5 cl, 3 dwg
