中文摘要：

设计了一种基于FPGA（EP1C12Q240）的数据遥传测试板,将其应用到（EILog测井系统的测试台架中。测试板具有CAN、DTB主控端和DTB仪器端通讯功能。CAN接口功能由FPGA内部控制逻辑和SJA1000芯片共同实现;DTB接口除少量外围电平转换电路外,控制逻辑及数据缓存功能均在FPGA中实现。该卡在软件的配合下既能模拟高性能地面系统及遥测短节对CAN和DTB总线井下仪器进行调试,也能模拟CAN和DTB总线井下仪器对高性能地面系统和遥测短节进行调试。

英文摘要：

A telemetry test board based on FPGA（field programmable gate array） is designed and implemented in the test bench of EILog system.The board has CAN,DTB telemetry cartridge and DTB tool communication capabilities.The CAN interface is jointly accomplished by SJA1000 and FPGA.FPGA and level conversion circuit together implement DTB communication function.With the support of software,it can not only simulate telemetry system debugging downhole tools,but also simulate various downhole tools for test of telemetry system and surface system.
