Components of PLC Control Systems

Components of PLC Control Systems

The hardware of a PLC mainly consists of several parts: the Central Processing Unit (CPU), memory, input units, output units, communication interfaces, expansion interfaces, and power supply.The CPU is the core of the PLC, while the input and output units serve as the interface circuits connecting field input/output devices to the CPU. The communication interface … Read more

Edge AI Applications for Low-Power Devices – Practical Project for Remote Meter Reading

Edge AI Applications for Low-Power Devices - Practical Project for Remote Meter Reading

This project is significant for the cornerstone project selection editor, as I have been engaged in the Internet of Things and edge computing fields, primarily working with microcontrollers/embedded ARM processors that are not designed for AI-capable computing devices.Although these devices are functionally stable, they struggle with data collection, remote monitoring, and intelligent management; moreover, in … Read more

Why Edge Computing and 6G Intelligence Will Continue to Be Aspirational

Why Edge Computing and 6G Intelligence Will Continue to Be Aspirational

One of the core visions of 5G is edge computing, sometimes referred to as Mobile Edge Computing (MEC). The idea is to enable Mobile Network Operators (MNO) to deploy computing resources closer to the base stations, thereby achieving ultra-low latency and allowing them to charge higher fees for premium services. Five years have passed, and … Read more

Unveiling the Core Mechanism of RS-485 Communication: The Key Role and Implementation Principle of 120Ω Termination Resistors

Unveiling the Core Mechanism of RS-485 Communication: The Key Role and Implementation Principle of 120Ω Termination Resistors

Common “Difficulties” in the Field One of the most troublesome issues during device debugging: RS-485 communication is unstable, with intermittent data transmission. The program logic is fine, the cable connections are correct, and there are no address conflicts, yet communication timeouts, data corruption, and sporadic failures still occur. Changing cables, adjusting baud rates, and checking … Read more

Building Ansible Execution Environment Images

Building Ansible Execution Environment Images

Building Ansible Execution Environment Images The construction of Ansible’s execution environment is essentially the construction of a container image, with Ansible providing a command <span>ansible-builder</span> to achieve standardized image building. <span>ansible-builder</span> will by default use the <span>execution-environment.yaml</span> or <span>execution-environment.yml</span> in the current directory as the execution environment definition file (which is the <span>Containerfile</span> or <span>Dockerfile</span>). … Read more

Analysis of the Impact of Back Power Distribution Network (BSPDN) on Power/Performance/Area/Temperature (PPAT)

Analysis of the Impact of Back Power Distribution Network (BSPDN) on Power/Performance/Area/Temperature (PPAT)

This literature is from IMEC, published in 2022, focusing on the impact of BSPDN on the study of PPAT.The front end (FEOL) is an active driver of chip power/performance/area (PPA). As scaling approaches the physical limits of semiconductor devices, the back end (BEOL)/middle end (MEOL)/packaging becomes increasingly important for PPA improvements in chips/systems. At 2nm … Read more
