CA2190836A1 - Communications protocol for remote data generating stations - Google Patents
A method for communicating data between a central data terminal (120), a plurality of intermediate data terminals (114), a plurality of remote cell nodes (112), and a plurality of network service modules (110), using a plurality of frames with each frame having a plurality of channels. The plurality of intermediate data terminals (114) transmit IDT-synchronization signals to the plurality of remote cell nodes (112) on a first channel of the frame. The plurality of remote cell nodes (112) transmit RCN-synchronization signals to the plurality of network service modules (110) on a second channel of the frame. The network service modules (110) transmit data from a plurality of physical devices, using radio waves, as NSM-packet signals to the plurality of remote cell nodes (112) using a fourth channel of the frame. The plurality of remote cell nodes (112) store the incoming NSM-packet signals and, responsive to a first polling signal transmitted in a third channel of the frame from a particular intermediate data terminal (114), transmit the NSM-packet signals to the intermediate data terminal (114) as RCN-packet signals on a fifth channel of the frame. The intermediate data terminal (114) in turn stores the RCN-packet signals received from the plurality of remote cell nodes (112) and. responsive to a second polling signal transmitted from the central data terminal (120) on a sixth channel of the frame, transmits the RCN-packet signals as an IDT-packet signal on a seventh channel of the frame to the central data terminal (120).
