Differences Between IoT Gateway and Industrial Gateway

PublishTime： 2023-10-26 Article Source：usr News

What is a gateway?

A gateway is a computer system or device that acts as a translator. Between two systems that use different communication protocols, data formats, or languages, or even completely different architectures. The gateway is a translator. Unlike bridges, which simply communicate information, gateways repackage the information they receive to suit the needs of the destination system. The gateway can also provide filtering and security functions.

What is an Industrial gateway?

An industrial gateway is an important industrial Internet of Things device, which is used to realize data exchange and transmission between different devices. It usually has multiple ports, supports multiple protocols, and can translate and bridge network protocols. So that different types of devices can communicate with each other. At the same time, Industrial Gateway also undertakes the tasks of safety management, equipment monitoring, and troubleshooting.

Advantages and disadvantages of Industrial Gateway

Advantage

It supports multiple protocols and interfaces so that different types of devices can be easily integrated into the same network.

Provides powerful security features that reduce the risk of device attacks.

It has high reliability and stability and is suitable for complex and high-load industrial environments.

Support remote management and monitoring, effectively reducing maintenance costs.

Shortcoming

The price is high and requires a certain input cost.

Configuration and management are complex and require professional operation.

There are certain security risks, and attention should be paid to strengthening network security management.

Industrial gateway application scenario

Industrial gateways are commonly used in the following areas:

IOT device access: connect various IOT devices to a unified network to realize centralized management and control of data.

Intelligent manufacturing: In the intelligent manufacturing system, the Industrial gateway plays the role of a bridge connecting different devices and data. It can optimize the production process and improve the efficiency.

Energy management: detect and collect energy consumption in real-time by connecting sensors or monitoring instruments.In order to achieve energy conservation and optimization.

Industrial automation: In the field of industrial automation, the industrial gateway can help to realize the connection and communication between various devices. It is convenient to realize automatic control and management.

IoT gateway, like the human brain, is the hub of the Internet of Things. The gateway will calculate, process, and transmit the data generated.

What is an IoT gateway?

In the architecture of the Internet of Things, a bridge is built between the perception layer and the network layer. That is "IoT gateway". It can realize both Wan interconnection and LAN interconnection. In addition, the IoT gateway also needs to have device management functions, and operators can manage the underlying sensing nodes through IoT gateway devices. Understand the relevant information of each node and realize remote control.

Characteristics of IoT gateway

Comprehensive perception, that is, using RFID technology, sensor access, two-dimensional code, and so on to obtain object information at any time;

Reliable transmission, networking through NB-IoT or LoRa, and integration with the Internet, real-time and accurate transmission of information;

Intelligent processing, using cloud computing, fuzzy recognition technology, edge computing technology, etc. To analyze and preprocess the data. Intelligent control of objects.

IoT gateway features

1. Protocol conversion

The protocol conversion from different perception networks to the access network, the unified encapsulation of the data in the standard format of the lower layer, and the guarantee of different perceptions. The protocol of the known network can become unified data and signaling. And analyzing the data packet sent by the upper layer into signaling and control instructions which can be identified by a sensing layer protocol.

2. Controllability and management capability

First of all, the gateway should be managed, such as registration management, authority management, state supervision, and so on. The gateway realizes the management of the nodes in the subnet, such as obtaining the identification, state, attribute, energy, and the like of the nodes. As well as remote implementation of wake-up, control, diagnostics, upgrades, and maintenance. Because the technical standards of subnets are different and the complexity of protocols is different, gateways have different management capabilities.

3. Data filtering function

Sometimes, sensors/devices generate a lot of data, which can put a lot of pressure on the system. And the cost of transmission and storage will increase accordingly. Usually, in this case, only a small part of the data is valuable and the rest is filtered out. For example, the camera does not need to send video data of the corridor. The gateway can pre-process and filter the data generated by the sensors/devices to reduce transmission, processing, and storage requirements.

4. Extensive access capabilities

At present, there are many technical standards for short-range communication, and standardization work for IoT gateway has been carried out at home and abroad. Such as 3GPP, sensors, and the Lora working group, to achieve the interconnection and interoperability of various communication technology standards.

In the development stage of the Internet of Things with serious fragmentation, no standard can directly achieve great unification like Qin Shihuang. But IoT gateway can "save the nation by curve" to some extent.

Differences between IoT gateway and Industrial gateway

IoT gateway and Industrial gateway are two different devices, and they have some differences in functions and application fields.

The IoT gateway is the core device connecting Internet of Things devices and the Internet. It can collect, process, and transmit data generated by IoT devices. IoT gateway usually uses wireless communication technology (such as Wi-Fi, Bluetooth, Zigbee, etc.) To communicate with Internet of Things devices. And transmit the data to the cloud platform or other systems for further processing and analysis. The main function of an IoT gateway is to realize the interconnection and data transmission between devices.

Industrial gateway is a device used in industrial control system, which plays the role of connection and interaction in industrial scenarios. Industrial gateways typically support multiple communication protocols (e.g. Modbus, Profibus, Ethernet, etc.). The ability to connect different types of devices, sensors, and controllers into industrial control systems. Industrial gateway can also be used for data acquisition, protocol conversion, security control, and other functions. To ensure the stable and safe operation of the industrial control system.

Therefore, the IoT gateway is mainly oriented to smart home, smart city, logistics, and other fields. Industrial gateway is mainly used in industrial automation and control systems. They have different design goals, communication modes, and functional features, and are used in different application scenarios.
