When operating buildings, bridges, structures, industrial facilities, certain factors arise that significantly reduce their service life. These are vibrations, mechanical stresses, static and dynamic loads, metal fatigue. They can lead to the destruction of structures, man-made accidents, significant financial losses, and unfortunately, to the victims. To avoid this or significantly reduce the risks of a tragedy, it is necessary to monitor the state of the object in real time and analyze the information received. For this, remote monitoring systems are used. They are a combination of sensors, data collection systems and a remote server. Sensors record temperature, vibration, mechanical stress, deformation, etc. At the monitoring site. The data collection system collects information from sensors, filters and analyzes it, and transfers it to a remote server. On the remote server, the data is processed, stored and presented to the operator in a visual form. If a potentially hazardous situation occurs (for example, the curvature of the bridge, or the vibration of the turbine has exceeded the permissible level), alarms will sound and alert maintenance personnel about possible problems and their occurrence. Also information about the current state of the object can be stored on the Internet for authorized access from anywhere in the world.
We propose to develop a system for remote monitoring, processing and presentation of data. Three types of monitoring systems are proposed, depending on the complexity of the task and the type of monitoring object.
- The simplest system is based on CompactDAQ platform and a personal computer (PC). CompactDAQ Chassis and data acquisition modules provide the collection of the necessary parameters and their transmission over the LAN to a PC or server, where the analysis and presentation of data.
- For applications where there is no possibility to collect data through a wired channel used Wireless Sensor Network (WSN) technology. These systems are self-powered and can transmit data over a wireless ZigBee network in a continuous period of operation without replacing batteries-up to 3 years.
- The third version of the monitoring system is based on a real-time controller CompactRIO platform. Application of these technologies allows you to create powerful multi-channel data acquisition system (and management) and to analyze the information received at the controller. This allows to send to the remote server is not the entire volume of information from the sensors and only meaningful information (for example, only the vibration transmitted to the server values exceeding critical).
You will always know the status of the object of interest, and be able to predict the occurrence of the defect. Based on the problems, we will design and develop data collection and processing system, user interface, data storage system.
