摘　　要：船载多传感器采集系统的设计需要满足数据采集的并发性、数据分析的正确性、数据传输的可靠性与数据处理的实时性等条件。基于实时操作系统(RTOS)设计一种新型的具有广泛适应性的船载多传感器采集系统,采用VxWorks作为传感器数据处理系统,利用其多任务并发的特性进行数据采集与数据处理,并与Windows系统协同工作,共同完成数据应用。设计中采用多任务并发、Socket通信等关键技术,对XBT和AirMar气象站两种传感器所采集的数据进行采集、处理及应用。Concurrency of data acquisition, correctness of data analysis, reliability of data transmission and real time of data processing are the prerequisites of designing in ship-borne muhi-sensor acquisition system. Design a new type of and universal ship-borne multi-sensor acquisition system based on realtime operation system（RTOS） , and due to multi-task concurrency characteristic of VxWorks, it is used to implement data acquisition and processing. Cooperate with Window system together complete data applications. Key technologies of multi-task concurrency and Socket communication are used in design, to handle acquisition, processing and application of data acquired by two types of sensors of XBT and AirMar.
