摘　　要：针对目前采油厂油井的工作参数监控缺乏远程手段的情况,论述了一种基于VxWorks的远程终端的设计。该远程终端采用CDMA通信信道,可以对油井的负荷、温度、油管回压、冲次、工作电流、工作电压等参数进行实时自动在线抄收和处理,并将数据发送至监控中心,由监控中心集中监控各油井的工作状态。该终端采用MSP430F149单片机完成数据的采集,由S3C44B0X嵌入式处理器完成数据的处理与发送,并由VxWorks嵌入式实时操作系统来保证高效率的实时多任务处理。At present, working parameters of well of oil production plant lack of remote monitoring means. The design.of a VxWorks - based Remote Terminal Unit （RTU） is dissertated in this paper. The RTU can real - time on - line collect and process the data of load,temperature,tubing pressure,stroke time,current,voltage of the oil pumping,etc. It sends the data to monitoring centre by CDMA channel. The monitoring centre centralizedly monitors the state of pumping wells. The RTU complete the collection of data by MSP430F149 MCU. Data processing and transmitting is done by S3C44B0X embedded processor. The VxWorks embedded RTOS manages the high performance multi - task real - time processing.
