Industrial Data Acquisition Applications Utilizing MYIR's MYC-JX8MMA7 ARM+FPGA SOM

With the development of communication and network technology and the Internet, the digitization, networking, and intelligence of industrial management have become an inevitable trend. The use of industrial Internet of Things (IoT) to complete industrial control is an essential part of smart factories. Traditional control and data acquisition systems struggle when the host needs to maintain high-speed communication with multiple data acquisition devices simultaneously, and undertake more complex data processing, while maintaining high-definition multimedia display functions, etc. The traditional industrial data acquisition hardware system falls short. However, embedded systems based on ARM and FPGA architectures, which come with rich peripheral interfaces, has high-definition display, and high-speed transmission capabilities, can also perform high-speed industrial data acquisition tasks in parallel. They are one of the essential choices for hardware upgrades in Industry 4.0.

The industrial data acquisition and control system mainly consists of two major structures. The first is the data acquisition system, which primarily uses FPGA processors for high-speed acquisition and obtaining of industrial protocol data; the second is the embedded control platform, which mainly uses ARM processors as the main control center for coordinating and managing the modules, resource scheduling, and at the same time receiving the data from FPGA, result visualization, and human-computer interaction. Using communication modules, the acquired data is transmitted to industrial MES+ERP systems, which not only reduces the risk of manual data entry but also saves on human resources.

The industrial data acquisition and control system can be mainly divided into high-speed data acquisition system and embedded human-computer interaction system. The two major systems are important components of the industrial automation data acquisition system and are essential industrial systems for upgrading to Industry 4.0.

High speed data acquisition system: The high-speed data acquisition system composed of FPGA chip and industrial signal acquisition system is an important way to quickly obtain industrial information data. Through various external data acquisition modules such as cameras, displacement sensors, high-precision ADC sampling modules, etc., FPGA chips perform parallel sampling processing and storage of the data signals from each module. Thus achieving high-speed industrial data acquisition function.

Embedded human-computer interaction system: As the core of the entire system, the human-computer interaction system sends acquisition command signals to the signal control system FPGA for data acquisition through SPI/PCIe. After data acquisition and processing, it is uploaded to the ARM chip for data processing and analysis through SPI/PCIe. On the other hand, it is possible to connect a mouse and keyboard via USB, manually input commands, perform script based automatic data capture, and display data results through a touch display system; Industrial MES+ERP systems can also be uploaded through the network for cloud storage of industrial data.
