What is an IoT Gateway?

An IoT (Internet of Things) Gateway is a device or software that serves as a bridge between IoT devices or sensors and the cloud or data center. It acts as an intermediary between the devices and the cloud, allowing them to communicate and exchange data with each other.

IoT Gateways are typically equipped with hardware and software components that enable them to interface with various IoT devices, such as sensors, actuators, and controllers. They also provide connectivity options, such as Wi-Fi, Bluetooth, Zigbee, and other wireless protocols, to connect to the Internet or cloud.

IoT Gateways perform a variety of tasks, including data aggregation, protocol translation, data filtering, and security. They also provide local data processing and analytics capabilities, which can help reduce the amount of data that needs to be transmitted to the cloud. This can help to reduce network congestion and latency, as well as lower data transmission costs.

The main functions of the IoT gateway:

  • Communication bridging and M2M communication.
  • Used as data cache, buffer and stream devices.
  • Real-time control of offline services and devices.
  • Aggregated data.
  • Preprocess, clean and filter data before sending it.
  • Additional intelligence for some IoT devices.
  • It provides additional security.
  • Device configuration and change management.

How does an IoT gateway work?

Most IoT devices in today's networks can aggregate data. For example, sensors in automobile traffic can aggregate data and send it to an AI analysis service in the cloud. But to reach the cloud, the sensors must first send all this raw data to an IoT gateway.

  • IoT gateways follow this simple process.
  • Preprocess, clean and filter raw data.
  • Translate protocols used for encryption and communication.
  • Send data to targets on the Internet or Intranet.

IoT gateway application environment

1. Power environment monitoring system

The power environment monitoring system is aimed at the equipment characteristics and working environment of various computer rooms (including communication, petroleum, electric power, subway, financial medical, education and other industries), and monitors the power supply, battery pack, UPS, generator air conditioner, etc. in the computer room. Intelligent, non-intelligent equipment and environmental quantities such as temperature and humidity, smoke zero, ground water, access control, etc. realize functions such as telemetry, remote signaling, remote control, and remote adjustment. The power environment monitoring system makes unattended computer rooms a reality, saving users A large amount of channel resource investment and operation and maintenance investment have reduced user operating costs.

2. Battery remote monitoring system

The battery remote monitoring system adopts micro-signal processing and high-precision satellite measurement technology to transform dumb equipment such as batteries into visible intelligent equipment, and realize the actual operating status, total voltage and current of the online long-term floating charge battery pack. Accurate monitoring of the voltage, internal resistance, and negative electrode temperature of each single battery can give early warning of battery failure, avoid vicious accidents in the computer room, reduce maintenance work safety risks, and reduce maintenance workload.

3. Energy consumption monitoring pipe embedded system

The energy consumption monitoring management system conducts real-time monitoring of the power consumption of small equipment, air-conditioning equipment, lighting equipment, power supply equipment and other systems in the computer room, conducts detailed statistics and analysis of equipment power consumption, and regularly generates various data reports to provide Suggestions for energy-saving renovation, and evaluate the energy-saving effects of various energy-saving measures, and obtain the optimal energy-saving measures and solutions under different conditions through analysis.

4. Intelligent access control management system

The intelligent access control management system is mainly to carry out safe and effective access control to the passages of the computer room. It consists of access control controllers, card readers, and electronic door locks. The system software is composed of remote control, IC/D swiping card, fingerprint, face and other ways to open the door. It supports independent networking, and can also be connected to the dynamic environment monitoring system through RS485/P for centralized management.

Finally: As an industrial computer for smart IoT security applications, most customers will choose to customize. A motherboard corresponds to a chassis, and serial ports, network ports, and expansion slots required by customers are often required to be corresponding, so each different Behind the IoT gateway system, most of the industrial computers used in various application environments are different machines, which are customized according to specific needs.

The 1U industrial computer is widely used in various IoT gateway scenarios. As the core component of the IoT gateway, it can realize the following functions:

Data collection and processing: Data is collected from various sensors, processed and analyzed to extract useful information.

Data transmission and storage: The collected data is transmitted to the cloud or other devices through various communication interfaces, and the data can also be stored locally.

Edge computing and decision-making: Local computing and decision-making, thereby reducing the burden of data transmission and cloud computing, improving response speed and security.

Safe and reliable: It has high security and reliability, and can protect the data and operation of IoT gateways and related devices.
