Communication networks distributed over a wide geographical area – such as those used for smart grids or in traffic management – are often limited to small bandwidths. Now information can be processed on-site in a virtual environment in the router, thus making room for more devices on the network – a key requirement for the Industrial Internet of Things (IIoT).
Thanks to new software for its Ruggedcom RX1400 router, Siemens is enabling applications and intelligence at the network edge. Ruggedcom is an extremely robust communication technology from Siemens specifically designed for rugged conditions. The new solution comprises a virtual environment that enables users to install their own Linux operating system on the router and run programs. For example, sensor data or camera images can be preprocessed in the router to keep the volume of transmitted data to a minimum.
More Efficient Use of Capacity
In addition to eliminating transmission bottlenecks and making communications more secure, the new software also contributes to a more efficient use of network capacity. In other situations it frees up space for transmitting additional information. Such a solution is especially beneficial, for example, for widely distributed communication networks such as those used in traffic management or smart grid control systems. These applications employ numerous sensors that are sometimes connected to a control center over long distances and transmit via connections – cable, fiber-optic, or mobile radio – with different transmission capacities.
A practical example of this is a router that has continuously transmitted data from a temperature sensor but now analyzes this information on site. The control center is notified only if given values exceed a defined threshold. Another example would be mobile monitoring containers such as those set up on large, remote construction sites. Such containers transmit a variety of information to a control center, including video data of the premises, usually via the mobile radio network. Instead of transmitting a continuous video stream, the router sends images only when something unusual happens in front of the camera, thus saving a great deal of bandwidth that can be used, for example, for a second video camera.
Fog Computing
Until now, on-site data processing required the installation of separate hardware in addition to the routers. The new solution – the Ruggedcom VPE1400 (Virtual Processing Engine) – comprises software that partitions off a separate virtual environment in the router where users can install a Linux operating system and load their own self-generated programs or those of service providers.
The partitions ensure that the programs never interfere with actual router operation – not even if the programs malfunction and, for example, take up too much processor power. The virtual environment enables an application to connect via all network interfaces on the Ruggedcom RX1400 router– LTE, copper, fiber-optic – and with serial transmission interfaces. Special application interfaces also enable communication with devices integrated into SCADA systems for control and monitoring purposes.
The new software is part of the trend toward communication networks with distributed computing capacities in which, as much as possible, data is processed on site rather than centrally. Experts refer to this as “fog” or “edge computing.” Such technologies are a key requirement for integrating a growing number of devices into an ever more distributed Industrial Internet of Things and operating them efficiently.
