Sensor system used for building-structure safety monitoring

Abstract

The invention proposes a sensor semantic system including sensor nodes, a local-area network, a monitoring-center server, the Internet and a text-message alarm module. The sensor nodes are arranged on parts to be detected and connected with the monitoring-center server through the local-area network. A built-in web server of the monitoring-center server provides data services or sends forewarning information to remote users through the Internet and forewarning text messages can also be sent through the text-message alarm module. The system is characterized in that the sensor nodes include a sensor information semantic module, a detected-point information semantic module and a sensed-data semantic module and the three semantic modules are associated through attributes and add a semantic background for data output by the sensor. An RDF (Resource Description Framework) is used to describe the three semantic modules and sensor information, detected-point information and sensed data are defined as resources on networks through a URI (Universal Resource Identifier). The sensed-data semantic module carries out semantic annotation on data so that semantic data are formed and then stored. When a storage space exceeds a limit, data saved at earliest time are covered automatically and at the same time, the semantic data are submitted to the monitoring-center server through a server interface module.

Description

technical field [0001] The invention relates to a sensor system for monitoring, in particular to a sensor system for building structure safety monitoring. Background technique [0002] With the rapid development of the national economy, real-time safety monitoring of buildings, bridges, tunnels and other infrastructure structures is of great significance for ensuring their normal operation and preventing major public safety accidents caused by structural disasters. The building structure safety monitoring system has become an important technical means to accomplish this task. The system integrates knowledge in multiple fields such as sensor technology, signal testing technology, and data transmission technology. It can test, store, and monitor various information of building structures. Continuous and real-time monitoring of the state of the building to strengthen the management level of building maintenance, ensure the reliability, safety and durability of the building stru...

AI Technical Summary

Problems solved by technology

With the passage of monitoring time and the increase in the amount of sensing data, there are greater difficulties in the management of sensors and the organization of sensing data

For the sensing data collected by the sensor, if there is no application background information such as sensor information and measuring point information, the data will also make the data meaningless
