中文摘要：

这份报纸为多极数组论述一个调试系统声学的记载(MPAL ) 工具。调试系统在这建议学习能调试 MPAL 工具系统，分系统和本地电子学。在测试设备，我们使用了主要、辅助的结构，并且经由以太网互连主机计算机和前端机器。前端机器基于 ARM7 (先进减少的指令集计算(RISC ) 机器) 技术，其处理器运用一个嵌入的操作系统，也就是 uClinux OS。我们分析了系统电信，人机器的接口电路，传输器心轴接口电路，接收装置心轴接口电路，和板级的测试接口电路。在系统使用的软件由嵌入的前面计算机软件和主机应用程序软件组成。我们详细在嵌入的前面计算机软件解释了靴子装载器的流动图表。主机应用程序软件由四个应用程序子程序组成，它与系统硬件的功能的模块匹配。一个网通讯程序借助于窝编程基于服务者 / 顾客模式被实现并且多线程编程。测试结果显示系统的数据传播率比 1 MB/s 高，它完全满足在工具系统和有线线路遥感勘测设备之间的数据传播率的当前的要求。调试系统的申请，包括多重水平测试方法，证明建议系统罐头充分在各种各样的层次满足 MPAL 的测试要求。

英文摘要：

This paper presents a debugging system for multi-pole array acoustic logging （MPAL） tools. The debugging system proposed in this study can debug the MPAL tool system, sub-system and local electronics. In the test equipment, we have used principal and subordinate structures, and interconnected the host computer and the front-end machine via Ethernet. The front-end machine is based on the ARM7 （advanced reduced instruction set computing （RISC） machine） technique, the processor of which runs an embedded operating system, namely, uClinux OS. We have analyzed the system telecommunication, human-machine interface circuit, transmitter mandrel interface circuit, receiver mandrel interface circuit, and board-level test interface circuit. The software used in the system consists of the embedded front-computer software and the host application software. We have explained in detail the flow chart of the boot loader in the embedded front-computer software. The host application software is composed of four application subroutines, which match with the functional modules of the system hardware. A net communication program based on the server~client mode is implemented by means of socket programming and multi-thread programming. Test results indicate that the data transmission rate of the system is higher than 1 MB/s, which completely meets the current requirements of the data transmission rate between the tool system and the wireline telemetry device. Application of the debugging system, which includes multiple level test methods, shows that the proposed system can fully meet the test requirements of MPAL at various levels.
