摘要船舶电网作为船舶的生命线，反映它运行的工作数据显得无比重要。船舶 电力系统是船舶的核心部分，船舶电力系统的稳定对于船舶的安全和可靠性非常 重要。船舶电力系统发展到今天，很多电气设备都安装在了船舶机舱里，这些设 备包括电力供应设备、船舶配电装置、用电装置、监测装置、通信装置以及控制 装置，因为这些电气装置的运转以及稳定对于船舶电力系统的安全运行非常重 要，所以我们就必须对船舶电力装置实施全面有效的监控。要想实现对于船舶电 网的监测，最重要是必须对这些船舶电气设备的电气参数和实时数据进行收集和 分析。本文设计了一种面向船舶整个电力的工作数据的无线采集系统；该系统由 前置电路、控制与数据无线传输电路和上位机客户端等三部分所构成。串口通讯 和 Labview 网络两种模式的实验结果表明了它能够实现数据采集频率远远高于 数据传输频率，数据通信速度能够到达毫秒，图形刷新速率达到秒级，能够充分 满足船舶电力数据采集与处理在精确度和实时性等方面的要求，保障船舶电力系 统稳定运行，所以这个船舶电力系统能适应于船舶电力系统的无线采集。82351

Abstract The electric power system is the lifeline of the ship, the working data of marine power system which reflects running state is very important。 The ship electric power system is the heart of the ship, its stability is very important for ensuring the safe and reliable running plays a role。 With the development of modern shipbuilding technology, high-end electrical equipment installed in the engine room more and more, the main power supply equipment equipment, power distribution equipment, electrical equipment, testing equipment, communication equipment and control equipment,Because the operation and stability of these electrical equipment is very important for the safe operation of the ship power system, so we must implement a comprehensive and effective monitoring of the ship  power plant。 In order to  realize the monitoring of the ship power grid, the most important is to collect and analyze the electrical parameters and real time data of the ship electrical equipment。We  introduce a design a wireless acquisition system of working data for marine power system。The system consists of a front end circuit, control and data wireless transmission circuit and PC client 。 Serial communication LabVIEW network model  of experimental results show that the it can reach microsecond data acquisition frequency,millisecond radio communication data rate,second graphics and refresh frequency,which can fully meet the requirements of ship electric power data acquisition and processing in  terms of accuracy and real-time, to ensure the stability of the ship power system,so the system can adapt to realize the wireless acquisition of the ship power system。
