Basic Data Acquisition System: A Design of ARM Processor based Embedded Ethernet Interface

In today's industrial landscape, efficient data acquisition and monitoring are crucial for ensuring optimal performance and minimizing downtime. One effective way to achieve this is by implementing an embedded Ethernet interface, which allows devices to communicate with each other over a standard LAN network. This paper presents the design of an ARM processor-based embedded Ethernet interface that enables web access to distributed measurement and control systems.

The proposed system is particularly useful for applications where devices do not have a built-in network interface, such as instrumentation, educational laboratories, and home automation. The design utilizes an ARM processor that can communicate with the network, making it an ideal solution for industrial applications where devices are often equipped with processors.

To develop this system, we divided the entire design into subcircuits, covering bridge rectifiers, relay drivers, and A-to-D converters. We also conducted software simulations of these subcircuits using LabView and IMAQ vision toolbox. The results of these simulations are presented in this paper, along with a detailed description of the hardware and software requirements for designing such a system.

The proposed system is highly useful for applications where devices have high dependence on specific temperatures. For example, it can be used to constantly monitor the temperature of a machine, compare it to a predefined limit, and shut down the machine if the temperature exceeds or falls below that limit. This feature makes the system particularly useful in industries such as manufacturing, where maintaining optimal operating conditions is critical.

In addition to its industrial applications, the proposed system also has potential uses in medical imaging and robotics. For instance, digital image processing algorithms can be used to interpret medical images and register and fuse different modalities, enabling more efficient image processing. In robotics, artificial vision systems can be developed using these algorithms to enable robots to interact with their environment in a more natural and efficient way.

In conclusion, the proposed ARM processor-based embedded Ethernet interface is an effective solution for data acquisition and monitoring in industrial applications. Its ability to communicate over standard LAN networks makes it an ideal choice for devices that do not have built-in network interfaces. With its potential applications in medical imaging, robotics, and other fields, this system has significant implications for a wide range of industries.
