Abstract:Combining the structural characteristics of a certain type of NBC defense equipment,taking equipment information collection, transmission, processing and application requirements for the traction,based on embedded system design program,this paper completes the software design and implementation of NBC defense equipment data terminal hardware. This data terminal equipment can collect and store self-test data, operational data, status data, fault data and alarm data and other information,as well as monitor real-time status of NBC defense equipment. Finally,it is tested to verify its accuracy for information acquisition,transmission and storage of a certain type of equipment and it can effectively guide the development of NBC defense equipment and supplement, management, maintenance and training activity, providing a basic, standardized information base for extended follow-up application development.
