Development of Technology of DSP Based Mechanical Vibration Data Real-time Ethernet Transmission

为了实现工业现场机械振动信号就地采集的实时数据传输,并根据多测点及大数据量数据采集的需要,提出了一种基于DSP控制的RTL8019AS实现机械振动信号实时以太网数据传输的设计方案.高速的DSP完成A/D芯片采集的数据的UDP和IP数据包的封装并通过对网络控制器RTL8019AS的寄存器的控制完成数据的实时传输.并根据需要精简了以太网的帧协议、TCP/IP协议,解决了以太网控制芯片RTL8019AS与DSP的接口技术,以及实现TCP/IP协议通信的技术,并进行了系统的调试与验证.

In accordance with the requirements of industrial mechanical vibration field data real-time transmission in the condition of multi-survey-point and mass data acquisition, an Ethernet data transmission method based on Ethernet controller RTL8019AS and TMS320C5402 DSP is presented. Packing data from A/D into UDP and IP package and controlling RTL8019AS through I/O mapped registers, high-speed DSP makes real-time communication high performance. Ethernet frame protocol and TCP/IP protocol are simplified for the specific purpose. And the interface technology between Ethernet controller RTL8019AS and DSP is solved. The system evaluation and debugging are made.
