设计舰船机舱状态数据采集与访问系统，为舰船机舱状态管理提供数据基础。现场数据采集单元选取模拟量采集卡，利用传感器节点采集舰船机舱状态数据，所采集数据通过路由单元的路由器节点传送至汇聚单元的协调器，利用协调器节点建立通信网络。通信网络将所采集数据传送至舰船机舱状态监测服务器中，舰船机舱状态监测服务器与访问控制单元结合，利用基于属性基加密的系统访问控制方法，划分系统访问用户为授权用户与非授权用户，授权用户通过执行二次解密获取舰船机舱状态数据明文，成功访问系统。系统测试结果表明，系统有效采集舰船机舱内的柴油机等设备参数，限制非授权用户访问系统，提升舰船机舱状态数据安全性。
Design a data acquisition and access system for ship engine room state data to provide a data basis for ship engine room state management. The on-site data acquisition unit selects the analog acquisition card, and uses the sensor nodes to collect the state data of the ship's engine room. The collected data is transmitted to the coordinator of the aggregation unit through the router node of the routing unit, and the coordinator node is used to establish communication. network. The communication network transmits the collected data to the ship engine room state monitoring server. The ship engine room state monitoring server is combined with the access control unit, and the system access control method based on attribute-based encryption is used to divide the system access users into authorized users and unauthorized users. , the authorized user obtains the plaintext of the state data of the ship's engine room by performing secondary decryption, and successfully accesses the system. The system test results show that the system effectively collects equipment parameters such as diesel engines in the ship's engine room, restricts unauthorized users from accessing the system, and improves the security of ship engine room status data.
