Smart control and sensor devices single wire bus multiplex system

摘要: Control of a plurality relay drivers by smart control devices and the continuous status monitoring switches associated sensors, wherein each device sensor is connected at separate single point on single-wire bus, are affected multiplex system. The system employs microcomputer driver receiver circuit for developing particular offset square wave pulse train which placed bus to provide power voltage signals sensors. contain circuits that respond form in manner causes drive an after chosen number polling cycles.
