(Russian, telesignalizatsiia), the reporting, over a distance and through telemechanic means, of information on the status of a monitored system (see). The English term “remote control,” in its broadest sense, is similar in meaning to the term “telemechanics” used here; the term “remote control” is used below in a narrower sense (see).
Remote signaling is the branch of telemechanics that deals with the transmission, over a distance, of discrete information on the state, or condition, of a monitored system (for example, open-closed or on-off) and with the presentation of the information in a form suitable for direct perception by the operator, for input into a control device, or for automatic recording. Remote signaling is used to carry out expeditious monitoring of switching operations at the monitored point and of the execution of the operator’s commands and to inform the operator if the values of the monitored parameters go beyond the permissible limits or if an emergency situation occurs in the monitored system. Often remote signaling is combined with remote control.
Remote-signaling means are sometimes used to transmit discrete measurement information, such as the number of articles produced, the number of loaded cars sent off, or the number of generators in operation. Remote signaling provides the operator with basic data needed to make control decisions and to initiate control actions. Signaling information can be transmitted by a combined remote-control and remote-signaling system, by a combined telemetering and remote-signaling system, or by a more complex telemechanic system.
