CPLD在测井仪器中的应用

应用CPLD（复杂可编程逻辑器件）技术，已经成为当今实现电子系统成化的重要手段，使用CPLD设计优化的新一代Manchester码接口板不仅在功能上完成了原有接口板的功能，并且加进了深度和张力系统，更加提高了地面系统的集成度，兼容性和可靠性，同样，在双晶C／O能谱测义井下电路中使用CPLD技术也达到了很好的效果。

Application of CPLD in Well Logging

Zhang Zhi, Han Dong. Application of CPLD in Well Logging Tool． WLT， 2001， 25（2）： 158－160 It’s a very important method to apply CPLD (Complex Programmable Logic Device) in integration of electron system. The optimized new interface board with a CPLD chip for Manchester code communication not only fulfills the function of the old one, but also adds the depth and tension system in it. The new board has better integration, compatibility and reliability. Furthermore, the downhole circuit of double detector C／O spectrum logging tool with CPLD also shows better application result.
