Abstract:In order to meet the demand and use of software to reduce the presence of low coverage, high cost, high packet loss rate, data acquisition frequency, proposed and designed the embedded ARINC429 interface board software testing platform based on. According to the structure diagram of ARINC429 interface board to design embedded software testing platform for user login security, design platform login authentication function; through the display of the embedded software running information, real-time monitoring of the running state of the software, so as to provide data acquisition and query support; design tool chain as code development and the structure of test tools; to improve software testing platform coverage through data acquisition, processing and transmission. Through the comparative analysis of the experiment, we can see that the test platform can improve test coverage, reduce packet loss rate, greatly increase the frequency of data acquisition, and provide a guarantee for the safe and effective operation of software testing platform.
