The HMI technology has revolutionised the industrial world, offering a completely new perspective on how we interact with machines and optimize their performance. From ATMs, vending machines, ticketing systems to home automation and smart factories, HMIs have become ubiquitous and an integral part of everything “SMART”. Recent developments in technology, IoT and edge computing have contributed to further sophistication of existing HMI technology, leading to much more intelligent and interactive interface.
In industrial settings, HMIs can be used to:
• Monitor machine inputs and outputs
• Quickly locate malfunctions and enable faster troubleshooting
• Track various problems and optimize manufacturing process to increase productivity
• Provide a realistic view of plant operations
• Remotely control the facility from a central location
• Easily test devices and equipment with simulations
• Reduce operation costs and simplify maintenance
• Improves communications among various types of equipment
• And more
Key challenges of the existing HMI technology:
Industrial HMI applications demands interface solutions that are extremely accurate and reliable. The algorithms that drive these applications may require continuous upgrades and design changes to meet the evolving market demands. An ASIC based HMI solution cannot scale up to these escalating performance requirements as they cannot be re-programmed.
Some of the key limitations of ASIC processor based HMI include:
• Inability to meet changing I/O and multimedia demands
• Failure to incorporate new and multiple value-added services
• High latency and response time due to increased processing time
• High power consumption and heat dissipation
• Limitations in peripheral interfaces
• No fail safe feature in communication standards
• Inability to manage concurrent applications efficiently
• Multiple processors to perform various applications takes up space and increase cost
• Complex physical design
How FPGA can overcome these limitations:
Adopting a reprogrammable FPGA architecture such as the Xilinx Zynq 7000 SoC can dramatically improve system performance and efficiency. The Xilinx Zynq 7000 SoC FPGA is a single device that can have different blocks to do different operations. This allows designers to utilize one piece of hardware flexibly, for multiple purposes. Since it can be reprogrammed, new features can constantly be added and fine-tuned to meet evolving design requirements.
iWave Systems is now offering advanced HMI platforms based on Xilinx Zynq-7000 System on Modules.
