As an important node connecting physical devices and the cloud, the edge computing gateway supports a variety of access methods, which can be categorized as wired, wireless, and industrial protocols, ensuring flexibility and compatibility and facilitating the flexible transmission of data from different devices. Through diversified access methods, it realizes local processing and real-time transmission of data, providing powerful support for IoT applications.
I. Edge Computing Gateway
Edge computing gateway connects the perception layer and network layer to perform functions such as data collection, protocol conversion, edge computing and local storage, helping to pre-process locally and reducing the computational burden of the cloud. Edge computing gateway can transfer data between the device and the cloud, realize the filtering and analysis of data, and ensure data privacy to a certain extent. The edge computing gateway can also perform remote monitoring and management, realizing real-time control and fault detection of industrial equipment.
II. Wired into the network
Stable transmission
Wired-in edge computing gateways mainly use Ethernet and optical fiber to provide stable high-bandwidth connections. It is used in scenarios where the network environment is stable and not mobile, such as factories, warehouses and other fixed locations. This method is superior in terms of data transmission rate and stability, and can cope with industrial control applications with high requirements for large data volumes and real-time performance. Although the wired method is stable and fast transmission, the deployment is more complex and limited by physical location. Once the environment changes, wired gateway rewiring and adjustment of high cost.
III. Wireless into the network
Flexibility and large coverage
Wireless entry gateway uses Wi-Fi, 4G/5G, LoRa and other wireless communication methods, which can quickly establish connections in scenarios that require frequent movement or temporary deployment. Wireless gateways are highly flexible, facilitating rapid device access and supporting wide-range coverage. Wireless methods are susceptible to signal interference, bandwidth limitations, and other factors, and their stability and latency can be significantly affected by the surrounding environment. In addition, long-term data transmission will generate high power consumption, suitable for places with continuous power supply conditions.
IV. Industrial protocols into the network
Industrial protocol compatibility
Devices and systems in industrial environments usually communicate using specific industrial protocols, such as Modbus, PROFINET, OPC UA, and so on. Edge gateways supporting industrial protocols can connect devices with different protocols to a unified network and realize interoperability between different devices through protocol conversion. Such a design is ideal for complex industrial environments where multiple devices and protocols coexist. Gateways for industrial protocols into the network have high compatibility and scalability in terms of protocol support, but they are also usually complex in design and require specialized configuration and maintenance. Deployment and operation costs are high, suitable for environments requiring standardized industrial interfaces.
