Internet of Things (IoT) gateways designed for sensor networks must constantly meet the high heterogeneity requirements of the cloud and the field. As a result, the IoT gateway forms the core of all communications and can be tailored to specific Application requirements are customized.
According to the MarketsandMarkets report, the IoT gateway market is expected to grow significantly between 2016 and 2022, reaching a compound annual growth rate (CAGR) of 14.2%. Second only to the general temperature operating gateways designed for office or home environments, the demand for industrial gateways designed for harsh environments is also enormous. After exploring the application market outside the operating temperature range of the office and the home environment, it is not difficult to find the distinctive features of the harsh environment-specific gateways that stand out in the mass market.
In addition to the market segmentation of ruggedness and durability - this is why developers love to use embedded hardware, which has a high degree of heterogeneity.
‧ Systems installed in the roof or basement of large public or private buildings must integrate heating, cogeneration, solar energy, elevators and walkie-talkies to provide operators with true all-round information.
‧ Substations often need to manage heterogeneous microgrids that contain various energy sources and energy storage systems.
• Train, aircraft or commercial fleet-specific systems need to integrate localized information and navigation systems, combined with the soundness of information entertainment, supply chain management and driving systems.
‧ Logistics applications are one of the most important markets for warehousing and transportation vehicle gateways.
‧ Oil and gas pipelines can be better monitored through cloud technology.
‧ Security monitoring is another important market, mainly including image monitoring systems and door and window sensors.
‧ Industrial gateways provide a wide range of sensor data and intelligent nodes for industrial applications.
‧Smart city uses include parking guidance systems, electric vehicle charging stations, and street lighting control systems.
Even with the application layer alone, the logic requirements of the gateway are full of high heterogeneity; the connection between the (wireless) sensor network and various communication protocols, and the communication between the various databases in the cloud. The lines are the same. The gateway acts as a two-way node and must act as a true master for communication and decision making. We need a system that collects sensor data, transcodes it after analysis, and then makes decisions based on the information we get. Data must also be properly processed to ensure consistency of data architecture and cloud transport. Finally, there must be two-way communication logic that communicates with the cloud solution, all with secure end-to-end encryption.
Keep in mind that application developers are primarily focused on the application layer, and the seven-tier ISO/OIS model requires a lot of extra work to evolve from a single component to a full-featured IoT solution.
For example, Germany's Congatec has developed a new cloud application programming interface (API) that allows solution providers to quickly and flexibly adapt to the specific needs of the IoT sensor network and the cloud. The cloud API is designed to simplify the work for OEMs by providing software modules that support applications, and enables customers to develop their own applications using blueprints. The principle is similar to hardware-level carrier circuit diagrams. Developers can also integrate end APIs designed for IoT gateways into any regional sensor network.
This API communicates with all types of area sensors, processes the data and converts the acquired data, and then analyzes it using the rules engine to make decisions from the regional side, which reduces traffic in the IoT cloud and accelerates response times. By using TLS to protect the security of the MQTT protocol, two-way data exchange with the cloud is realized, and the protocol and the Internet of Things cloud itself can be replaced.
The advantages of the cloud API function module in C++ programming have been confirmed by connecting to the Bluetooth LE sensor network. Reference designs for other wireless sensor networks, such as ZigBee or LoRa, as well as wired solutions for building and industrial automation, can also be implemented, with more advanced implementations including heterogeneous configurations and immediate, fast-area data exchange. Large equipment with additional gateway connection communication. The best example of this implementation possibility is the Industry 4.0 connection equipment and system. In the demonstration version of the system, the cloud API is integrated into the IoT gateway that can be expanded with the Qseven module, providing a wide range of expansion options for the customer's specific configuration needs. This open, best practice solution is ideal for OEM customers to evaluate their specific IoT applications.
Among the best practice solutions for supporting applications, the most important software components include cloud API functional modules and demonstration and test modules for independent IoT clouds from various vendors. The Cloud API software module uses a sensor engine to integrate independent communication protocols and devices, as well as communication links between sensors and actuators. The software module also normalizes the recorded data into a definable entity unit and checks for consistency. The Operating System (CGOS) library integrates all relevant gateway system parameters such as CPU workload, CPU and motherboard temperature, intrusion detection, hard disk status, and watchdog timer. The rules engine allows the zone gateway to define instant messages and actions in any connected state, while the communications engine is responsible for standardizing encrypted independent vendor cloud communications over wired or wireless internet connections.
The demonstration and test module of the Internet of Things cloud allows developers to define cloud data storage, further establish central messages and rules for controlling IoT applications, define other upgrade scenarios, and provide dashboards for remote clients. However, the core functionality remains in the cloud API, including access to the IoT gateway and its regionally connected sensor network.
The Cloud API collects a large amount of physical data from the Bluetooth LE sensor. The data is then processed and encrypted in the IoT gateway, and transmitted to the cloud along with the gateway status data (such as CPU temperature). The data is integrated and displayed in the cloud. On the online dashboard.
