Telemetering and Remote-Signaling System


a type of telemechanic system used to monitor the condition of systems and to measure their parameters at a distance. The term “telemechanic,” as used here, is similar in meaning to the English term “remote-control” in its broadest sense (see).

Depending on the way in which the values of the measured quantities are presented, telemetering apparatus may be classified as analogue or digital. For telemetering, the error depends on the class of system and ranges from 0.25 to 4 percent.

An example of a telemetering and remote-signaling system is the Soviet Telekompleks system. It is used for the rapid collection, processing, and presentation of information in automated load-control systems for power systems or groups of power systems. The Telekompleks can handle up to 32 monitored points, which may be, for example, power substations. These points may be located at distances of up to 14,000 km from the control center. The data are transmitted through wire lines or radio communication channels. Each monitored point can receive up to 80 telemetering signals carrying measurements of, for example, current, voltage, or frequency. In addition, each monitored point can receive up to 736 remote-signaling signals; such signals may indicate, for example, that a certain unit has been connected or that a certain line is under load. In the event of large quantities of measurement information, the data are processed by computer. The control board at the control center of a telemetering and remote-signaling system may have up to 3,000 indicators for binary signals and up to 256 digital meters.
