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.
