摘要
基于C8051F020的测井数据采集系统是利用专用的字符叠加芯片uPD6450,在C8051F020控制下,将采集到的温度、压力、深度数据与井下CCD摄像机产生的视频信号进行叠加,实时直观地显示井下状况,并采用USB方式与工控机进行通信,做到即插即用。该系统在测井过程中的应用表明系统工作稳定。
To show the situation of well logging in real time, a system display CCD video of the well was designed. Temperature, pressure and depth signals sampled by C8051F020 were overlapped on the video. The system used USB to communicate with industry computer. The application of well logging shows the system works stably.
