A Microcontroller Unit (MCU) is an integrated single-chip computer that combines a central processing unit (CPU), memory, input/output (I/O) interfaces, and various communication interfaces. MCUs are commonly used to control a wide range of electronic products, such as the devices in the rapidly developing Internet of Things (IoT) ecosystem, where they can perform functions like sensor detection, data collection, and data transmission to gateways. Due to their compact size and cost-effectiveness, MCUs play a crucial role in both industrial computers and consumer electronics, finding applications in various fields, such as industrial automation, robotics, smart manufacturing, and the gaming market. Depending on the specific application requirements, the market offers a variety of MCU options, ranging from high-performance multi-core processors to energy-efficient low-power processors.
In the context of industrial computer systems, chassis intrusion is a critical task in ensuring the safe and reliable operation of the equipment. Historically, CPU’s limited capability to continuously detect chassis intrusion when the system is powered off has caused management inconveniences and insufficiency. To tackle this challenge, Portwell has designed and developed an innovative chassis intrusion solution based on MCU technology for its partners. This solution remains operational even when the system is powered off, ensuring uninterrupted chassis intrusion, and effectively safeguarding the security and uptime of industrial equipment.
Portwell’s chassis intrusion solution utilizes a low-power MCU acting as an independent control unit. Equipped with specialized hardware peripherals, the MCU can directly interface with chassis switches and other sensing components enabling real-time detection of chassis intrusion. In battery-powered mode, Portwell’s R&D team has thoroughly optimized power-saving strategies. They have implemented various low-power modes to ensure the MCU can operate with minimal power consumption to extend battery life. Additionally, the team has meticulously designed the firmware, to ensure the MCU can perform the chassis intrusion tasks efficiently and reliably. To enhance the user/operator experience, Portwell has packaged the data transmission and processing functions into APIs, which support mainstream operating systems like Windows and Linux. Users/operators can directly access the required data through these APIs, without the need for in-depth research on MCUs and programming.
Drawing on an innovative MCU-driven approach, Portwell has launched a robust chassis intrusion solution equipped with optimized functionality and high reliability. Not only can it continue detecting chassis intrusion when the system is powered off, but it also ensures extended battery life and operational uptime. In addition, it excels in terms of hardware interfaces and communication protocols, positioning it as an industry-leading solution. Portwell’s services go beyond the off-the-shelf solutions that we provide customized design services tailored to the unique needs and requirements of individual use case. Based on specific application scenarios, our team carefully selects the most suitable MCU models and further optimizes both hardware and software to ensure the final product precisely aligns with user requirements. This development project has garnered the trust of Portwell’s partners and stands as a significant achievement in the industrial computer field. Looking ahead, Portwell remains committed to customer-centric services and technology-driven innovations, DMS, continuously delivering innovative and specialized custom solutions.
