Design of automatic detection system for optimal access path of embedded network database

传统的嵌入式网络数据库最优访问路径自动检测系统在检测过程中覆盖率低,准确性差。针对上述问题,设计了一种新的系统,硬件由采集器模块、处理器模块和检测器模块三部分组成,利用CAN总线连接硬件设备。采集器模块的运行系统为PC104系统,内部装有16 GB CF卡存储器,配合软件工作,选用智能采集通信节点C805 1 FO103作为通信节点;处理器模块内部拥有寄存器单元、算术逻辑单元、输入/输出单元,通过EAD-STROBE脉冲控制信息输入,利用WEARFAFAVD脉冲信号执行输出操作。软件分为系统上电复位、信息采集、信息处理三步。为检测系统工作效果,与传统系统进行实验对比,结果表明,给出的检测系统覆盖率更高,准确性更好。

A new system is designed in view that the traditional automatic detection system for optimal access path of embedded network database has low coverage and poor accuracy in the detection process.The system hardware consists of three parts,named collector module,processor module and detector module.The CAN(controller area network)bus is used to connect the hardware equipment.The operation system of the collector module is PC104 system,equipped with 16 GB CF card memory to work with the software.The intelligent acquisition communication node C8051 FO103 is used as the communication node.The processor module is internally provided with the register unit,arithmetic logic unit and input/output unit.The EAD⁃STROBE pulse is used to control the information input and WEAR⁃FAFAVD pulse signals are used to perform the output operation.The software is divided into system power⁃on reset,information acquisition and information processing.Contrastive experiments were performed to detect the working effect of the system.The results show that the proposed detection system has higher coverage and better accuracy.
