EMQ is based to build a new generation of massive equipment access electric IoT platform
With the new electric IoT strategy, the State Grid is making efforts to promote the construction of a unified IoT management platform . This will realize cross-discipline data sharing to achieve practical results in transmission and transformation, distribution station area, customer side, supply chain, and other fields. During the construction of the IoT platform, it is necessary to define a large number of heterogeneous terminal management and access through software, and support the concurrent access of millions of devices, while carrying a large number of message consumption.
Challenge
Traditional platforms can't carry a huge number of electric power devices that access at the same time
The number of smart devices in the power industry is huge, and the construction of the electric IoT platform by provincial power grid companies often needs to support the access capacity of more than one million devices. The traditional IoT management platform is difficult to cope with.
Compatibility difficulties with industry and IoT access protocols
In various production environments of transmission-transformation-distribution-use, the existing devices mainly communicate with IEC104, DL/T698.45, I1, and other power industry protocols. With the gradual increase of power devices communicating with MQTT IoT protocols, compatibility access and management of multiple traditional power protocols and IoT protocol devices has become a major difficulty in the construction of a new generation power IoT platform.
is difficult to adapt to the existing northbound device management platform
The old device management platform is usually managed by establishing a separate connection for each device. In the process of connecting the new generation power IoT platform with the existing device management platform, it is necessary to bridge the data between the new platform and the existing platform through a large concurrent one-to-one connection.
Solution
EMQ power IoT solution provides millions of concurrent long connections through EMQX, a cloud-native distributed IoT access platform, which supports distributed cluster deployment and flexible horizontal scaling architecture on demand. In the device access layer architecture of the IoT management platform, using the high-performance EMQX cluster as the platform access module, MQTT connections and TCP connections for a large number of IoT terminals can be carried with a small number of infrastructure resources.
The solution supports the unified access of IEC104, DL/T698.45, and I1 protocols based on TCP protocol, which is transformed into MQTT protocol to achieve unified and efficient data transfer in the access layer. Combined with EMQX's MQTT, LwM2M/CoAP, and other IoT protocol access capabilities, it meets the access layer requirements of unified protocol access and high concurrent connections for the power IoT platform.
EMQX uses optimized bridge configuration read and write efficiency to achieve more than 100,000 levels of northbound bridging capability in EMQX clusters, meeting the one-to-one routing capability between devices and upper management platforms in power application scenarios. Thus breaking the business bottleneck between the new platform and the customer's existing device management platform.
Results
- Quickly realize the one-stop 10 million IoT platform access capability and greatly shorten the R&D cycle.
- Based on EMQX's high-performance access capability and high concurrent communication modules, multi-protocol unified connection services and large connection and high traffic connection management can be achieved with relatively small hardware resources. Thus saving more than 50% of hardware resource cost compared to other access layer solutions.
- It provides massive real-time data for the whole life cycle control of smart devices, one-stop IoT application management, and other IoT ecological applications, and provides powerful support for the "accurate sensing, edge intelligence, unified IoT, open sharing" power IOT intelligent IoT system.
