Industrial gateways are able to connect industrial devices and sensors for data collection and transmission. It has powerful data processing capabilities and efficient communication protocols, and is able to handle massive amounts of real-time data. At the same time, the industrial gateway also has high reliability and stability, which can meet the complex environment requirements of the industrial site. With the development of the Industrial Internet of Things (IIoT), industrial gateways are playing an increasingly important role in connecting devices, sensors, and control systems. Through data collection, the industrial gateway collects, converts and processes the data of equipment and sensors, and provides basic data support for factory intelligence, industrial automation control, remote monitoring, data analysis, etc.
Data collection method for industrial gateways.
1. Direct connection to the device: The industrial gateway directly connects the device through the serial port, Ethernet port and other communication interfaces to collect data from the device. For some devices that support standard communication protocols, industrial gateways can collect data through the corresponding communication protocols.
2. Connect sensors: The industrial gateway monitors the operating status of the equipment in real time by connecting sensors, such as temperature, pressure, displacement and other sensors. For some smart sensors, the industrial gateway can collect data through the corresponding communication protocol.
3. Connect to the control system: The industrial gateway can be connected to the control system, such as PLC, DCS, etc., and collect the operating status and parameters of the equipment by reading the data of the control system. For some control systems that support standard communication protocols, the industrial gateway can collect data through the corresponding communication protocol.
4. Through the linkage between gateways: In complex industrial environments, industrial gateways can realize automatic data collection and transmission by deploying the linkage between multiple gateways. This linkage can be achieved through preset rules and trigger conditions, which increases the flexibility and efficiency of data acquisition.
5. Data preprocessing: In the process of data collection, the industrial gateway can preprocess the data, such as filtering, summarizing, calculating and other operations, to improve the quality and availability of data. This pre-processing can help users better understand and utilize the collected data.
6. Selection of data transmission protocol: When transmitting data, the industrial gateway can choose different communication protocols and formats according to actual needs, such as MQTT, HTTP, OPC UA, etc. These protocols and formats can meet different application scenarios and needs, ensuring reliable data transmission and compatibility.
7. Data security: In the process of data collection and transmission, the industrial gateway needs to ensure the security of data. Encryption algorithms can be used to encrypt data to prevent data leakage and tampering. At the same time, reasonable access rights and authentication mechanisms should be set up to ensure that only authorized users can access and manipulate data.
8. Data storage and management: The industrial gateway needs to store and manage the collected data. You can use local storage or cloud storage to choose according to your actual needs. For the storage and management of large amounts of data, a distributed database or big data storage scheme should be considered to improve the efficiency and scalability of data management.
9. Data analysis and application: The data collected by the industrial gateway can be used for further data analysis and application. Machine Xi, artificial intelligence and other technologies can be used to mine and analyze data to discover the application value of equipment operation rules, failures and maintenance. At the same time, the collected data can be integrated with the business system to realize the sharing and application of data, improve production efficiency and reduce operating costs.
