PURPOSE:To decrease the time required till a set reserved packet or an emergent data packet is correctly received by a center station without collision by dividing a transmission data into plural numbers as subpackets, copying an emergent data and sending it as plural subpackets. CONSTITUTION:When a length data 3-2 is received, it is divided into five, data 1, data 2, data 3, data 4, and data 5, a header such as its own station address and subpacket information are added to each data and the result is sent as subpackets. When an emergent data 3-3 is received, copy number =4 is decided based on the received traffic status signal and traffic control signal, the emergent data is copied for times, a header such as its own address and subpacket information are added to each of the five emergent data in total to form subpackets and to send 3 subpackets. Thus, the emergent information reaches the center station in a short time without being reset by a terminal station. |
