摘要： A control system for selectively communicating a plurality of sensors (17) with associated remote control devices (19, 20) includes a Master Synchronizer (10), a transmitter (11, 12) for each sensor and a receiver (13 14a) for each control device. A single signal line (14) is connected to all transmitters (11, 12) and receivers (13, 14a), and a single synchronization line (15) couples the Master Synchronizer (10) to all transmitters and receivers. The Master Synchronizer (10) generates a time frame signal which has a reset portion for resetting all transmitters and receivers synchronously at the start of each frame, and a periodic portion which determines the time slots for each frame and which decrements counters (31, 38) in all transmitters and receivers synchronously. A time division multiplex system is used to communicate each transmitter with one or more associated receivers during a predetermined time slot of a periodic time frame determined by the Master Synchronizer.
