利用FPGAProASIC3模拟串口实现多极子阵列声波仪器与RTU的通讯

To Realize Communication between Multipole Array Acoustic Logging Tool and RTU with FPGAProASIC3 Simulated Serial Port

多极子阵列声波测井仪器是通过测井公司的高速数传系统挂接在慧眼2000地面系统上,多极子阵列声波仪器与高速数传之间利用RTU连接,RTU是远程终端单元,是通用的井下仪器与数传的接口。多极子仪器与RTU之间的通讯方式是异步串口UART。多极子仪器采用的控制芯片是DSP5509,不具备串口UART功能,因此采用FPGA模拟串口来实现井下仪器与RTU的通讯。该文介绍了利用FPGA模拟串口实现多极子阵列声波仪器与RTU的通讯的实现方法。

Multipole array acoustic logging tool is connected to 2000 surface system with a high- speed digital transmission system by a remote terminal unit( RTU), which is a interface between common downhole in-struments and data transm ission. The communication mode between the tool and RTU is asynchronous se-rial UART. The control chip is DSP5509 which does not have serial port UART. Therefore FPGA Simula-ted serial port is used. This paper introduces how to use FPGA simulated serial port to communicate the multipole array acoustic logging tool with RTU.
