Abstract

PURPOSE:To attain a data collection without repeating a bisecting search by using an actual data telegram for a terminal response to a dichotomy polling from a center in a bisecting polling system. CONSTITUTION:When data transmission from a terminal having transmitting data is promoted by a bisecting polling command 6 with all terminals as a range by a command transmitting device 51 of a center 5, a response telegram 8 is sent from a terminal (for example, terminal 2) having the transmitting data in place of the response. In the response telegram 8, the address of the terminal 2) is also included in addition to the actual data and the actual data are collected by the center 5. When an ACK (acknowledge) signal originating device 53 instructs the terminal 2 to release the data link based on the obtained address information and a transmission completing signal receiving device 54 receives an ACK receiving confirming signal from the terminal 2, a next polling is shifted.
