iQunet wireless sensors use a ‘pull’ communication protocol. To save battery life, sensors are in sleep mode most of the time. Within milliseconds of being awakened, the sensors share data, receive new settings from the iQunet server, and share status information with the iQunet OPC UA server running UNIX. You can configure the ‘wake’ frequency to the requirements of your own installation.
The software running on the sensors is both powerful and efficient, ensuring that the batteries will last for several years.
The iQunet OPC UA UNIX server runs a web server which makes it possible to communicate with the sensor network. The server can be contacted using a WebRTC-ready browser. A peer-to-peer communication network is automatically established, and the intuitive Sensor Dashboard is displayed.
The dashboard can be used to manage sensor status information or set burst intervals for automatic measurements. Data is relayed to the iQunet OPC UA server. It can also be previewed using dynamic graphs on the Dashboard.
The software controls the sensor measurements and can perform basic data analysis if a vibration monitoring sensor is connected. Sensor Dashboard software can process user requests for live data and export data to analytical software from third parties.
The iQunet UNIX Server runs an embedded OPC UA (unified architecture) server. OPC UA extends the standard, and highly successful, OPC communication protocol. It enables data acquisition and allows for data modelling and reliable and secure communication between the plant floor and the enterprise. OPC UA is future-ready, easy to configure, and maintain.
For quick and easy reporting, iQunet created a Google Sheets/Microsoft Excel export tool. The tool transforms spreadsheets into a reporting tool for process and equipment data. By connecting in real-time to the iQunet sensor network data source, sample reports can be created quickly. Production, quality, and performance reports are simple to generate. The tool does not require any installation and is managed from the wireless Sensor Dashboard.
A GraphQL server also runs on the iQunet UNIX server. GraphQL is a query language for APIs and a runtime environment to fulfil those queries using existing data on the iQunet UNIX server. GraphQL provides around 200, fully documented iQunet APIs. There is a complete and understandable description of the data in the API, giving you the power to ask for exactly what you need. Powerful developer tools are available. Using a single, but evolving version, GraphQL APIs give applications continuous access to new features and encourage cleaner server code which is easy to maintain.
