congatec is showcasing a best practice design approach for the simplified orchestration of wireless sensor networks at Embedded World (hall 1, stand 358). It is based on the new, application-ready congatec Cloud API (Application Programming Interface) for IoT Gateways that is capable of integrating any local sensor networks into any cloud system.

congatec’s new Cloud API for IoT Gateways communicates with local smart sensors, processes and converts the acquired data and executes automated actions based on a local rule engine, reducing traffic to the IoT cloud and enabling fast local actions. Secure bidirectional data exchange with any suitable clouds is achieved by using the TLS secured MQTT protocol. The best practice design utilises the Microsoft Azure cloud. Clients can access this cloud via https in client or administrator mode. All these features make the new congatec Cloud API for IoT Gateways a useful starting point for OEMs that need to access smart sensor networks via IoT gateways and IoT edge servers. Typical application areas can be found in various IoT segments, from industrial production and machinery to smart cities, smart facilities, smart homes, smart energy grids, medical IoT, the transportation sector and digital signage.

The new Cloud API from congatec impresses with its application readiness and built-in openness to integrate a broad range of wireless sensor interconnects, including Bluetooth LE, ZigBee, LoRa and other LPWANs, as well as wired protocols for building or factory automation via one single Cloud API. Even heterogeneous protocol configurations and communication with other gateways are possible. Typical applications for the latter scenario are Industry 4.0 connected machines and intra-logistic systems.

Christian Eder, director of marketing at congatec explains: “Each smart sensor network has its own demands. Often, heterogeneous sensor networks are required and various different database implementations can be found in IoT clouds as well. At the edge of the IoT we are able to manage these heterogeneous, bidirectional demands by centrally orchestrating local smart sensor networks including the IoT edge gateways themselves. Our application ready congatec Cloud API for IoT Gateways meets this demand. Its freely programmable software modules can be instantly utilised to get access to our boards and their data as well as connected sensor networks. They are available in C++ and can be used as a blueprint for any custom specific implementations. which highly simplifies the development of individual IoT solutions.”

The main software components of congatec’s system are the different Cloud API function modules as well as the demo and test modules for provider independent IoT clouds. The sensor engine of the congatec Cloud API for IoT Gateways makes the communication with the local sensor and actuators independent from any protocol. In addition, it normalises the data records to freely definable physical units and checks for consistency. The congatec operating system (CGOS) library integrates relevant gateway system parameters, such as system temperatures, CPU workload and intrusion detection.

The rule engine enables the gateway to locally initiate warnings and automated actions if certain values exceed or threaten to exceed a defined threshold. Finally, the communication engine takes care of encrypted and provider independent data cloud communication via wired or wireless internet connections. The IoT cloud evaluation software provides the required tools for consolidating the sensor data in the cloud. In addition, they can establish central messaging and control rules for the connected IoT applications, define further escalation scenarios and provide dashboards for remote clients.

congatec provides OEMs with all required software modules in the C++ source code on request, which simplifies the development of own IoT applications for Linux and Windows based on this application ready reference design. On demand, congatec also provides additional software services for the Cloud API and its cloud connection. Go to www.congatec.com for more details.
