The industrial IoT gateway is a very important part of the IoT system. For industrial equipment, the IoT gateway is a bridge to communicate with the outside world. The industrial IoT gateway enables distributed industrial equipment to realize data interaction, and then communicates with the Internet through the IoT gateway. The gateway has powerful protocol parsing capabilities. The IoT gateway can collect the corresponding data of various PLC, instrumentation and other equipment and support MODBUS reading and writing, support 4G, 5G, WIFI, wired Ethernet, optical fiber, LORA and other networking access methods, and support the realization of industrial Remote debugging, diagnostics and upload and download procedures for devices.
What is an Industrial IoT Gateway? The Role of an Industrial IoT Gateway
1. What is an Industrial IoT Gateway
The WG593 series industrial IoT gateway independently developed by IOT is a three network port, two serial ports, supports 4G/3G/WIFI/LORA and other network access methods, supports various industrial control protocol analysis and data collection , supports the acquisition of multiple analog inputs, multiple digital inputs and multiple digital outputs, supports LORA data transparent transmission, supports cloud platforms that report data through MQTT, supports local configuration and remote configuration deployment, and supports implementation at edge nodes An embedded comprehensive industrial IoT gateway that integrates functions such as data acquisition, computing and storage, remote control, VPN and firewall.
2. Introduction to the role of industrial IoT gateways
2.1 Rich interfaces and easy deployment
Support 4G, 3G, PPPOE, Wi-Fi network, LORA, digital IO input and output, serial terminal communication, and provide different access solutions for different applications.
2.2 Internet of Everything and Efficient Access
Embedded protocol analyzer, supports mainstream industrial control protocols and customized unique protocols; realizes local calculation through policy rule calculation and application deployment and distribution, and improves the control ability and real-time performance of the device.
The embedded communication protocol WDCP realizes the standardized access of complex machine types in the field, not only can realize data aggregation to the data center for calculation and storage, but also realize remote control and remote release.
2.3 Build a high-performance, high-concurrency application system
Support various edge computing rules (smart collection, data filtering, alarm calculation, grouping strategy, etc.) and standardize the data to reduce the pressure on the cloud service center, thus greatly improving the robustness and high concurrency of the system; Support access to third-party high-performance service suites to achieve high concurrent access, saving project R&D and construction costs.
2.4 High reliability embedded system design
2.4.1 Gateway link detection design: support real-time link detection, realize automatic re-pulling of dropped calls, and maintain long-term link connections.
2.4.2 Gateway fault self-healing design: Embedded hardware watchdog and software watchdog technology, equipment running fault self-healing, to ensure that the equipment maintains high availability.
2.4.3 Gateway Security Guard: Through the system security guard, the system status and application status are detected in real time to prevent and restore the system's unsafe and unstable nodes.
2.5 Powerful security features
2.5.1 Data transmission security: Support L2TP, PPTP, IPSec VPN, Open VPN, and CA certificates to ensure secure data transmission.
2.5.2 Network protection security: powerful firewall function, can customize a full range of protection strategies according to customer needs, such as support for SPI full state detection, Secure Shell (SSH), intrusion protection (Ping prohibited), DDoS defense, attack defense, The firewall functions such as IP-MAC binding protect the network from external attacks.
2.5.3 All nodes provide authentication and end-to-end encryption services. These nodes include devices and various cloud services. The IoT suite also provides device-level permission granularity services. This service ensures that devices or applications only have corresponding access permission to operate certain resources.
