During the operation of 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, technological accidents, significant financial losses, and unfortunately, to the victims. To avoid this or significantly reduce the risks of tragedy, you must constantly monitor the state of the object in real-time and analyze the information received. For this, remote monitoring systems are used. They are a collection of sensors, data acquisition systems and a remote server. Sensors record temperature, vibration, mechanical stress, strain, etc. at the monitoring site. The data acquisition system collects information from sensors, filters and analyzes it, and transfers to a remote server. On a remote server, data is processed, stored and presented to the operator in a visual form. When a potentially dangerous situation arises (for example, the bridge curvature, or turbine vibration exceeded the permissible level), alarms are triggered and alert service personnel of potential problems and where they occur. The same 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 most simple system is based on the CompactDAQ platform and a personal computer (PC). The CompactDAQ chassis and data acquisition modules provide for the collection of the necessary parameters and their transfer over the local network to a PC or server, where the analysis and presentation of data takes place.
- 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.
