| This paper presents the upgrade and modification design of the SL-3000 model digital-controlled logging system, which consists of two important modules - communication control module and acoustic wave VDL (Variable Density Logging) module. The working principle of these two modules, hardware architecture, circuit design and the implementation of the PCI interface are also expatiated. Based on the hardware platform , the principle and development method of device driver under Windows operating system are introduced. The development process of virtual device driver based on PCI9052 is also provided. |
