摘　　要：针对机床物联网系统中多紧急度数据调度的要求和数据通信稳定性的要求,在机床物联网系统中采用了RT-thread实时操作系统,通过对mailbox进程通信机制的改进,满足了数据优先级调度的需求,提高了系统对紧急数据优先处理的能力。通过采用socket通信技术,满足了网络重负载通信的要求,在硬件上采用了ARM Cortex-M3处理芯片和W5100网络通信芯片。通过实验仿真,证明了本系统大幅度提高了机床数据处理的实时性和可调度性。The design and implementation of the machine tools internet of things system based on RT- Thread. To meet the demand of multi-urgency data scheduling and data communication stability, RT-Thread real-time operating system is used. The improvement of mailbox thread communication model satisfies the need of data scheduling priority, enhance the system＇ s ability to give a priority to urgent data. The use of Socket can meet the need of network heavy load communication. Employ ARM Cortex-M3 processing chip and w5100 network communication chip in hardware. The experiment result proved that the system can largely improve the real-time and Sheduling of machine tools data processing.
