[导读]在老旧产线改造中，常有大量RS485 Modbus RTU设备（温湿度、电表、变频器）需要接入上位机或MES，但它们不支持TCP。此时用Raspberry Pi（树莓派）运行Modbus TCP↔RTU网关程序，既能做协议转换，又能充当边缘数据预处理节点。本文基于Raspberry Pi OS + pymodbus库，给 ...

We are standing at the end of an era we never thought to mourn: the era of human-speed threats. For years, cybersecurity moved to a rhythm organizations could follow. A researcher found a bug, a CVE ...

Which technology should I study to increase my market value? Since becoming an engineer, I have seen this question many times. And I myself have been searching for that answer for a long time. Should ...

[导读]在产线设备中，PLC常作为主控单元负责工艺流程，FPGA作为高速算法加速/多路采集前端。两者之间通过Modbus RTU（RS485）或 ...

2026年的小程序开发市场，正在经历一场静水深流的范式转移。一方面，AI技术的突飞猛进让开发门槛前所未有地降低——AI几小时就能生成小程序的基础框架，市场报价从2018年的20万-30万被压缩至2万-3万，行业陷入“价格战”的红海。另一方面，企业对小 ...
