Charon visualization and monitoring software

Taking its name from Greek mythology, Charon is the software that binds all sensing data together in one platform. Compatible with all LIOS sensing products and a range of third party sensors, Charon can combine data from multiple sources and store them in a common SQL database. From the database, the sensing data can be presented both visually in one big overview where you can quickly get a status on the entire installation being monitored, or split up in graphs, tables or any other format you may want.

Charon is a user-friendly and easy-to-learn software application for storage and visualization of data from LIOS distributed temperature sensing (DTS) systems. Data from point data sources and optional En.Sure Real-Time Thermal Rating (RTTR) results are also stored and visualized by Charon.

The measurement data is stored in a powerful SQL database for convenient access. Data visualisation presents desired information in a comprehensive manner. The enhanced visualisation options of Charon4 offer various customisable views of data. Data export, import and software interfaces support third party tools. Optional En.Sure RTTR provides real-time information about conductor temperatures of power cables.

Technical Background

Charon is a multithreaded 64-bit (or 32-bit) Windows application. State-of-the-art object oriented software techniques are adopted using the Qt framework. Measurement and configuration data is stored in a powerful SQL database using a database server.

In a standard installation, database, communication services and visualisation client are installed on a single PC. Network installations with a central database and several clients can be used in applications with several users accessing the same data.

A Windows software package and maintenance procedure can be used for installation, update and removal. Communication with the DTS systems can be established over TCP/IP connections. Data compression algorithms are applied for efficient communication and minimum use of data storage. Data integrity is guaranteed by the use of cryptographic hashes. The GUI (Graphical User Interface) of Charon4 is compliant with modern Microsoft Windows standards in order to offer intuitive operation to the user. A concept of user levels with different access rights is used to protect sensitive settings. The display language can be changed. Further display languages can be easily implemented using the LIOS Technology translation tool.

Database

Measurement data is stored in a SQL database on the user PC or optional on a database server with huge storage capacity normally sufficient for several years. Historic measurement data can be deleted automatically after a user-defined period. With this feature, measurements can be run for unlimited time without overloading the database. Measurements during alarms, fibre breaks, errors and other events can be excluded from automatic deletion or deleted after a longer period. High availability and safety of data can be achieved by running two databases in parallel. DTS systems communicate with the database over a network via UDP and TCP/IP protocols.

Visualisation Capabilities

Various data types of DTS systems and other data sources (e.g. temperature profiles, temperature history, zone data, point sensor history) can be shown synchronously in different windows or on multiple screens.

DTS, data sources, structures and user-defined enhanced views are listed in a tree-view NAVIGATION window with project folders.

Properties of a selected project, DTS, fibre, data source, structure or enhanced view are shown in the PROPERTIES window (name, alarm and failure status, IP address, …).

Temperature profiles from several channels can be visualized on a common CHART window. The charts can be scaled and zoomed. Reference curves and curves from the repository can be added for comparison.

Zones from all DTS systems within a project can be visualized in a common ZONE VIEW window. Zones can be sequenced according to status, temperatures and other criteria in order to show most relevant information always on top.

The HISTORY window can show the history of temperature data at selected locations and data from point sensors.  Temperature data can be visualized in a contour plot showing temperature as false colour over time and location. All windows are updated in real-time.

Structure Monitoring

Structures combining data from several DTS can be easily defined and visualized. The structures enable the combined visualization of large or long installations, plants, tunnels, cables or pipelines that are monitored by multiple DTS. It also allows to combine data from different DTS monitoring the same area using certain rules (minimum, maximum or average). This feature is especially useful for safe monitoring of structures using redundant DTS installations.

Enhanced View

The optional ENHANCED VIEW can be used for custom visualization of installations. Custom pictures, maps or drawings can be used as background. Zone, temperature and point sensor data can be visualized using different shapes for numerical, colour or chart displays.
