Network Security Keyword Search Drive Data Backup Test System

摘要:

传统数据处理系统在测试网络安全关键字搜索驱动备灾数据时，花费成本高、测试精度低、误差率高。为了解决上述问题，设计一种新的测试系统，分别对系统硬件和软件进行设计，系统硬件主要由采集器、处理器、存储器、传输器组成，采集器选取PL3200采集芯片，实现多功能采集;处理器选用SOC处理器，能够同时处理多类型数据;存储器选用的是STM32存储器，降低系统工作延时;传输器采用HDMI传输器，提高系统兼容能力。软件由安全数据划分、测试计划编写、测试环境构建以及测试结果检测四部分组成。为检测系统性能，与传统系统进行了实验对比。实验结果表明，所设计的测试系统的平均相对误差比传统测试系统低10.09%，系统花费成本比传统测试系统节约了近1500千元。由实验结果可得所设计的备灾测试系统能够有效降低成本、减少误差率。

Abstract:

Traditional data processing system tests the network security keyword search to drive the disaster recovery data, the cost is high, the test precision is low, and the error rate is high. In order to solve the above problems, a new test system is designed, which is designed for system hardware and software. The system hardware is mainly composed of collector, processor, memory and transmitter. The collector selects PL3200 acquisition chip to realize multi-function acquisition. The processor selects the SOC processor and can process multiple types of data at the same time; the memory selects the STM32 memory to reduce the system working delay; the transmitter uses the HDMI transmitter to improve the system compatibility. The software consists of four parts: security data partitioning, test plan writing, test environment construction and test result detection. In order to test the performance of the system, an experimental comparison was made with the conventional system. The experimental results show that the average relative error of the designed test system is 10.09% lower than that of the traditional test system, and the cost of the system is nearly 1500 yuan less than that of the traditional test system. Experimental results show that the designed disaster preparedness test system can effectively reduce the cost and reduce the error rate.
