To manage and control a complex IoT environment with multiple connectivity options and protocols, energy profiles, dispersed systems, and an ever growing number of connected devices requires a critical component called Edge Gateway. Gadgeon has packaged ready to use IoT Gateway based on open source components running on OpenWRT Linux distribution, which is generic and can be easily ported and customized to custom designed hardware for any market segment and needs.
Gadgeon has extensive experience in developing and deploying Edge Gateway based on off-the-shelf or custom designed hardware platforms and open source software components for various customers. Gadgeon’s Edge gateway software package is thoroughly tested for scalability and security using Gadgeon’s automated testing frameworks.
When it comes to Edge Gateway considerations, there are few options the customers can choose from:
Option 1: Off-the-shelf Edge Gateway platform - hardware + software, only configuration, and provision can be done. Need to depend on equipment vendor for any customization.
Option-2: Off-the-shelf IoT Gateway HW platform + open standard based SW platform with required customization - typically 90% of use cases can be addressed with this option
Option-3: Custom HW & open standard based SW platform with required customization - this option need to be considered for cases where the above options are not feasible
Our recommendation would be to go with Option-2 till the pilot is completed or limited volume is deployed if the form-factor and Ultra Low Cost are NOT must requirements. Advantages - no hardware design/ development required initially; customer can focus on solution and features and proving the value of the solution; SW ownership is with the customer so that customer has the flexibility with the feature set and customization.
Go to option (3) when volume pushes the business for lower HW cost or form-factor as a MUST to have requirement. With minimal cost and schedule, we should be able to move the completed software from Option -2 to Option-3.
Key success factor for any commercial IoT implementation is the ability to collect data from equipment or devices and then transfer the collected data to cloud server through a secure connection. Gadgeon has developed an IoT gateway – ‘thingway’ for commercial IoT implementation. ‘thingway’ is a cost effective industrial IoT gateway design. The gateway can be remotely maintained via remote firmware updates from the cloud.
This IoT Gateway with its highly optimized cost and features enables commercial deployment in large volumes in domains like remote monitoring and outdoor applications. thingway is designed to be weather and tamper proof for infrastructure monitoring. Cellular 4G/3G/2G connectivity enable the use of the system in remote locations where no other communication infrastructure is available, like telecommunication towers.
The gateway can collect data from devices in the field through wired (RS485/RS232) or wireless interfaces (WIFI, ZigBee). Devices could vary based on the exact use case, but some of the examples are generator sets, battery management systems, energy meters, HVAC etc. Gateway sends the data to the cloud platform using protocols like MQTT, REST API, CoAP.
thingway can collect data from Smart meters through ZigBee, RS232 or other interfaces and collect the data. The system can also collect demand response signals from the utility and control the power usage accordingly. Gateway can connect to the internet using Ethernet, Wi-Fi or cellular interface
thingway can be deployed in a wide range of home automation applications. It can talk to wireless ZigBee or Z-wave devices using add on modules on the PCIe interface. Uplink can be supported over Ethernet, WiFI or cellular interfaces.
DelEdge is an Industrial IoT Gateway from Gadgeon. DelEdge is a Linux based field gateway software that runs on any industrial grade off-the-shelf hardware which can be deployed on premise. DelEdge is a field Gateway located on the factory floor which connects existing PLC, SCADA system and legacy equipment for data collection and aggregation. It supports all major industrial PLCs from Siemens, Mitsubishi, Bachmann, OMRON, etc. and harmonizes different protocols like Modbus, BACNet, OPC-UA, PROFINET, HART-IP before sending data to the Cloud database. The DelEdge gateway is a must-have equipment to address round trip network latency from cloud server and to realize near real-time experience for monitoring via local HMI. Docker based implementation facilitates easy upgrades and modularization of protocols and functionality. Features of DelEdge include:
