| Abstract: | A kind of character-overlay board based on CPLD.for deep-well detection is introduced.It can not only complete current depth measure of detector , but also display the depth data on video image in real time, and when video signal is off , it can still display the depth information continuously. In addition, depth measure related to data acquisition can be realized by means of connecting the character-overlay board to other DAQ systems via RS232, so the whole system can work synchronously. Application indicates, it has high reliability, measure precision, can find application in oil-field, water conservancy etc . |
