1. Product Introduction
The WISENMESHNET
®
Vibrating Wire (VW) Interface Node is one of the key products in our
patented WISENMESHNET
®
geotechnical safety monitoring system. Working together with the WISENMESHNET
®
gateway product and our customers VW type sensors, it intelligently delivers the real-time VW derived deformation of
the structure to the information centre.
The WISENMESHNET
®
VW Interface Node operates using our core technology, i.e., the WISENMESHNET
®
Low Power,
Intelligent, Wireless Sensor Network protocol, together with its internal high precision frequency sampling module and
power unit. This interface node is compatible with conventional geotechnical vibrating wire type sensors measuring in
the range from 400 to 6000Hz. This product satisfies the three fundamental identities of the system:
A. Network Life Span: to maximise battery life across the mesh network as a whole;
B. Network Data Arrival Rate: to minimise data packet loss;
C. Single Node Environmental Coverage: to maximise radio coverage.
Our product has IP66 and is designed to work in a tough environment. It is small in size, reliable in performance, easy
for maintenance, has high precision during sampling, and has strong immunity to radio-interference.
