While developing IoT systems and complex apps one may need to link large number of IoT and sensors and various automation control systems that produce big data streams. PharosN enables digital transformation of such streams into custom analytics and sustainability statuses of any object in the system as well as the system as a whole in real time providing effective answer to the question “How are you my System?”
The linking is implemented by common high level communication protocols using https as transport. It allows for generic solutions avoiding specific proprietary requirements and restrictions by hardware manufacturers or various low level protocols.
The platform can meets the challenges of unified data collection supporting operations of such objects as machines, vehicles, robots, buildings, offices, homes as well as large industrial systems having heterogeneous data sources.
The data is received in a JSON file. For example, HVAC control system has a couple of thousands sensors connected over BACnet. Having TCP/IP gateway local controller collect data from all devices each 45 seconds and saves the results in one json file. The file is read by Rest API and the local controller/gateway acts as a single point of collection for all sensor readings, its processing and sending to custom IoT system app running under PharosN where is processed into various analytics for customer monitoring and visualization in a assets control center.
In case of industrial automation and relevant management systems, the installed sensors can be linked to OPC engines or SCADA or MES systems controlling large number of devices and processing relevant data.
The custom IoT app @ PharosN can communicate with such systems and IoT through common open access protocols collecting (get) or receiving (push) big data in json files. While sensors or actuators data is received over different industrial protocols such as ModBus, BACnet, KNX, etc, the relevant additional controllers – bridges allow for data streams receipt using standard open-source protocols COAP, SOAP, MQTT and SNMP using various software frameworks like AllJoyn and Iotivity providing access to sensor readings via Rest API. IN case of OPC XML-DA and OPC UA servers, industrial networks, the custom IoT app @PharosN can use these protocols as well.
The SOAP protocol is most common in industrial systems. The use of SNMP protocol is recommended mostly for closed networks e.g. LANs due to the fact that has shortcomings in security.
The dotted block in the Picture refers to the systems which are not described here but allow access to monitoring functions via some network protocols. If the protocol is missing in the list it can be promptly implemented by the PharosN development team upon request. Some new standards and relevant technologies under implementation will be supported in the releases of the platform upgrades.
IoT app @ PharosN can automatically import the stored sensor data from structured databases or files using its data import procedures as well.
