Amid the wave of deep integration between Industry 4.0 and the Internet of Things (IoT), the role of industrial computers is evolving from a single data acquisition terminal to an "intelligent control hub" with capabilities in edge computing, AI decision-making, and multi-protocol conversion. PUSR's industrial pc USR-EG628, an industrial fanless pc, redefines the performance boundaries of industrial IoT devices with its "four-in-one" architecture (edge computing + AI computing power + communication capabilities + control capabilities).

 

1. The Core Value of Industrial Computers: From Data Acquisition to Intelligent Decision-Making

Industrial PC (IPC) serves as a bridge connecting the physical and digital worlds, with its core value upgraded from traditional "data acquisition and transmission" to "local real-time decision-making + cloud-based collaborative management." The breakthroughs of Industrial PC EG628 include:
