COMMUNICATION SYSTEM AND COMMUNICATION METHOD |
摘要 |
<p>A communication device 1 has a first protocol analysis section 11 that analyzes a status of a transmission signal Vs received at a transmission signal receiver 10. A transmission controller 14 determines a communication available period and a communication unavailable period based upon the analysis result. When the communication available period is determined, the transmission controller 14 allows a second protocol signal transmitter 12 to transmit a packet in accordance with a second protocol to a signal line Ls. With this result, it is possible to transmit a relatively large amount of data while suppressing noise influence caused by a varying condition of a carrier, in contrast to a prior system in which the transmission signal is superimposed only by a simple determination of the carrier condition. Thus, it is possible to share the signal line Ls with the time-division multiplexing transmission system and improve reliability of data transmission.</p> |
