GeoNet Wireless Network (VW) | Model 8800 Series
Mạng không dây Radio modem GeoNet kết nối tín hiệu dây rung Geokon 8800 Series
GeoNet is a low-power, wireless data acquisition network developed to more efficiently collect data from many points. The system consists of a Network Supervisor (8800-2) and up to 100 Single-Channel Sensor Nodes (8800-1). The supervisor controls the network and is the aggregator of all the data collected by the nodes. Sensor Node Multiplexers are available, which expand the capacity at each node to 8 channels, thereby allowing clusters of closely spaced sensors to be added to the system. The system is compatible with all GEOKON Vibrating Wire instruments¹. GeoNet is built on top of the IEEE 802.15.4 standard. The network is self-healing and will reconfigure itself, if possible, to tolerate disturbances to the physical environment. This topology is more flexible than star networks, in that communication can be established around obstructions. Up to 12 networks can coexist by setting each to a different operating frequency (channel).
