The Application of Cellular Modem in Industrial AI: How to Achieve Intelligent Decision-Making?
In the industrial sector, a transformation driven by artificial intelligence (AI) is surging forward. Industrial AI is no longer just a sci-fi concept; it has been literally, "tangibly and solidly"  integrated into every link of the production process, bringing unprecedented efficiency improvements and cost optimizations to enterprises. In this transformation, the Cellular Modem (Data Transfer Unit) acts like an unsung hero working behind the scenes, playing a crucial role. This article delves into the application of Cellular Modem in industrial AI and how it helps achieve intelligent decision-making.

1. Cellular Modem: The "Data Bridge" of Industrial AI
Imagine an industrial site as a vast and complex maze. Various industrial equipment are like treasures hidden within the maze, constantly generating massive amounts of data. This data contains key information such as equipment operating status, production efficiency, and quality indicators. However, these devices are often scattered in different locations and use different communication protocols, much like the intricate passages within the maze. The role of the Cellular Modem is to build a "data bridge" connecting these devices and the industrial AI system. It collects data dispersed in every corner and transmits it to the AI system in a unified format and standard.

Ucloudlink IoT's cat-1 dtu USR-G771 and CELLULAR MODEM USR-G786 are two excellent examples of such "data bridges." USR-G771 adopts cat-1 communication technology, offering advantages such as low power consumption, wide coverage, and low cost. It is particularly suitable for industrial scenarios where the data transmission rate requirement is not extremely high but cost and power consumption are more sensitive, such as simple equipment monitoring in small factories and environmental data collection. It can stably transmit device data to the cloud or a local server, providing basic data support for the industrial AI system.

On the other hand, USR-G786 is a CELLULAR MODEM with high-speed and stable data transmission capabilities. In industrial scenarios with high real-time data requirements, such as equipment status monitoring on automated production lines and cargo location tracking in intelligent warehouses, USR-G786 can quickly and accurately transmit data to the AI system, ensuring that the AI system can obtain the latest information in a timely manner and make accurate decisions.

2. Data Collection and Preprocessing: Laying the Foundation for Intelligent Decision-Making
The primary task of an Cellular Modem is data collection. It connects to industrial equipment through various interfaces, such as serial ports and Ethernet ports, to collect real-time operating data of the equipment. This data may include various parameters like temperature, pressure, rotational speed, and production output. However, the collected raw data often has issues such as noise and missing values, making it unsuitable for direct AI analysis. At this point, the Cellular Modem needs to have certain data preprocessing capabilities.

Taking USR-G771 as an example, it has built-in simple data processing algorithms that can perform preliminary screening and cleaning of the collected data. For instance, it can remove obviously abnormal data points and perform simple interpolation on missing data to ensure the quality of the data transmitted to the AI system. USR-G786 has even more powerful data processing capabilities. It can not only perform data cleaning but also conduct simple data analysis and conversion, such as unifying data in different formats into a format that the AI system can recognize, providing a high-quality data foundation for subsequent intelligent decision-making.

3. Real-Time Data Transmission: Enabling the AI System to "See and Hear Clearly"
In industrial AI, real-time performance is of utmost importance. A production failure can occur in an instant, and if not detected and handled promptly, it may lead to production stoppages, product quality degradation, and other problems. The Cellular Modem transmits the collected and preprocessed data to the AI system in real-time through a stable network connection, allowing the AI system to understand the situation in the industrial site in a timely manner and make rapid responses.

Although USR-G771 uses cat-1 communication technology, it can also ensure real-time data transmission under good network coverage. It can reasonably allocate network resources based on the importance and urgency of the data to ensure that critical data is transmitted to the AI system with priority. The 4G network of USR-G786 provides higher transmission speeds and lower latency. It can quickly transmit a large amount of data to the AI system, enabling the AI system to analyze the operating status of equipment in real-time, predict potential failures, and issue warnings in a timely manner. For example, in a large-scale mechanical processing workshop, USR-G786 can transmit the operating data of each machine tool to the AI system in real-time. When the vibration data of a certain machine tool shows abnormalities, the AI system can immediately issue an alarm, notifying maintenance personnel to handle it in a timely manner to avoid equipment damage and production interruptions.

4. Collaborative Work with the AI System: Achieving Intelligent Decision-Making
The close collaboration between the Cellular Modem and the industrial AI system is the key to achieving intelligent decision-making. After receiving the data transmitted by the Cellular Modem, the AI system uses various algorithms and models to analyze and mine the data, extracting valuable information and patterns. This information and these patterns can help enterprises optimize production processes, improve product quality, reduce energy consumption, etc.

For example, in a chemical production process, USR-G786 transmits data such as the temperature, pressure, and liquid level of the reaction kettle to the AI system in real-time. Through the analysis of this data, the AI system can accurately grasp the progress and status of the reaction. Based on preset models and rules, it can automatically adjust reaction parameters such as temperature and pressure to ensure that the reaction is always in the optimal state, improving product quality and output. At the same time, the AI system can also predict the equipment maintenance cycle based on historical and real-time data, arrange maintenance plans in advance, avoid sudden equipment failures, and reduce maintenance costs.

5. Case Sharing: Cellular Modem Helping Enterprises Achieve Intelligent Decision-Making
Let's take a practical case to more intuitively feel the application of Cellular Modem in industrial AI and how it achieves intelligent decision-making.

An electronic manufacturing enterprise introduced Ucloudlink IoT's USR-G786 CELLULAR MODEM and connected it to various equipment on the production line, such as surface mount technology (SMT) machines, reflow ovens, and inspection equipment. USR-G786 collects real-time operating data of these equipment, such as the placement speed and accuracy of the SMT machine, the temperature curve of the reflow oven, and the yield of the inspection equipment, and transmits this data to the enterprise's industrial AI system.

After analyzing the collected data, the AI system found that the placement accuracy of the SMT machine fluctuated when mounting certain specific types of components. Through further analysis, the AI system identified the root cause of the problem: the wear of the SMT machine's nozzle led to insufficient suction. As a result, the AI system automatically generated a maintenance task, notifying maintenance personnel to replace the nozzle in a timely manner. At the same time, the AI system also optimized the temperature curve of the reflow oven based on historical and real-time data, improving the welding quality and reducing the defective rate.

By introducing the Cellular Modem and the industrial AI system, the enterprise's production efficiency increased by 20%, the defective rate decreased by 15%, and the maintenance cost decreased by 10%, achieving significant efficiency improvements.
