Sensor Based Bridge Monitoring System

Resensys was founded in 2008 with the mission of protecting infrastructure systems against aging and malfunction . For this purpose, Resensys developed a global network to supply its high precision, durable and reliable structural monitoring solutions to customer applications including bridges, tunnels, buildings, dams and cranes.

Based on its award winning ultra low power wireless sensor network technology, known as SenSpot™, Resensys provides a powerful platform for remote monitoring of strain (stress), vibration (acceleration), displacement, crack activity, tilt, inclination, temperature, and humidity.

Having monitored all these important structural quantities in real time, SenSpot sensors provide reliable tools to measure overstrain, metal fatigue, formation of cracks, movement and stability of foundation, as well as monitoring vibration and performing modal analysis. Currently, Resensys’s SenSpots are the world’s most energy efficient wireless monitoring sensors and a SenSpot sensor provides a minimum of 10 years of monitoring using a small CR123A battery.

SenSpot™(Wireless Sensors)

SENIMAX™(Data Acquisition)

Resensys SeniMax™ is an ultra low power and high performance data collector and remote communication gateway. SeniMax™ communicates with SenSpot™ sensors using IEEE802.15.4 protocol. Wireless communication between SeniMax™ and SenSpot™ sensors uses unlicensed ISM 2.4GHz band. SeniMax™ has capability to transmit the aggregated data from SenSpot™ sensors to any remote data center with Wi-Fi, Ethernet or cellular data services (depending on the model). Different versions of SeniMax™ for remote communication using HSPA, Verizon CDMA network or using GPRS network are available. Additionally, SeniMax™ can be used as a data logger, where it receives data of SenSpot™ sensors, and stores them. The logged data can later be transferred to a computer.‍

A single SeniMax™ device can cover up to 250 SenSpot sensors in its communication range. SeniMax is ideal solution in applications of distributed sensing and data acquisition where there is no access to main power or communication infrastructures. Particular applications include: structural integrity monitoring for highway bridges, airframes, construction projects, pipelines, etc.

SENSCOPE™(Software)

Resensys SenScope™ is for real-time monitoring and structural diagnostics based on measurements of Resensys SenSpot™ sensors. SenScope™ is capable to reduce large volume of data of Resensys SenSpot™ sensors into specific structural diagnostics information. The information generated by SenScope™ facilitates decision-making and accelerates the course of action for maintenance/repair.
