The core of equipment health management in spaceflight launch site is information system. In order to get effective equipment health management, we need to obtain complete information, comprehensive interconnection, deep information applying. The requirements of equipment health management in spaceflight launch site based on information system include intelligent management means, professional management troops, perfect management mechanism, and management information environment. Based on these requirements, the paper analyses the general architecture of equipment health management in spaceflight launch site. The general architecture mainly includes resources management architecture, operation logic architecture, application representation architecture, and basic facilities architecture. Also, the paper designs and describes the level architecture of equipment health management in spaceflight launch site. The general architecture and the level architecture are the basis for spaceflight launch site to achieve scientific equipment health management.%有效的设备健康管理需要推进更完整的信息获取、更全面的互联互通、更深入的信息应用。对基于信息系统的航天发射场设备管理的需求进行了分析，主要有：智能化的管理手段、专业化的管理队伍、配套化的管理机制和信息化的管理环境。根据上述需求，分析了航天发射场设备健康管理的总体架构，主要包括资源管理架构、业务逻辑架构、应用表现架构和基础设施架构；设计和描述了航天发射场设备健康管理的层次架构。基于信息系统的航天发射场设备健康管理架构，能够为航天发射场实现科学的设备健康管理奠定基础。
