    摘要: A repeater for use in a two way communication system for retransmitting information between a first device and a second device to help ensure reliable two way communication between the devices, comprising: a transmitter/receiver, the transmitter/receiver receiving signals from the first and second devices and transmitting the received signals for reception by the respective first and second devices; and further wherein a direct communication path for the information between the first and second devices is provided, the direct communication path being intermittently unreliable, the repeater providing an additional path for the information between the first and second devices; the repeater being spaced from said first and second devices by a specified distance, said specified distance being significantly less than a theoretical maximum communication distance thereby to ensure communication reliability. A plurality of repeaters can be provided in the system as the overall system expands when additional first and second devices, such as master units and control devices, are added. The plural repeaters employ a repeater transmission sequence in order to ensure reliability of communication. In addition, the repeaters build a bit map of status information received during the repeater sequence to ensure that all status information is received by each master unit.

    摘要: A communication protocol for a two way transmission system having at least one first transmitter/receiver device, at least one second transmitter/receiver device and at least one repeater for relaying signals between the first and second devices. The protocol includes the steps of transmitting a first signal comprising a command from the first device, repeating the first signal with each repeater in a respective repeater time slot, receiving the first signal at the second device, transmitting status information from each second device in a respective status time slot, forming a status bit map comprising all status information in the at least one repeater, and transmitting the status bit map with the repeater so that the at least one first device has received the status bit map. Preferably, the transmission system comprises an R.F. communication system. If a plurality of repeaters are employed, the repeaters repeat the transmitted signals in a defined repeater sequence. The repeaters build a bit map of all status information received by the respective repeaters during the repeater sequence. In this way, it is assured that all first and second devices receive those signals intended for the respective devices.
