摘要随着航海工业的发展，急需对航海的每一项参数进行及时的收集和测控，收集和测控又脱离不了对于数据的采集以及分析，数据收集技术现在成为很重要的组成成分。因为高科技的在这几年的进步，我们的需求已经远远赶不上时代的发展，光电发展迅速，各种各样的信息都需要我们去收集和归纳还有加密，但是国内的科技水平在这块灵越并没有涉及很深相反欧洲的一家跨国公司所垄断，价格因此也比较昂贵，简单的说我们需要拥有属于自己的技术。但是国内涉及很浅，在这个方面都没有深入研究，我主要是利用传感器来模拟海上的很多类数据，比如说先研究船舶的静态数据 然后研究他的动态数据。船在海上行驶会遇到各种情况，风平浪静的话和海啸等天气的数据运动轨迹是不一样的。在这里我们要实现对船的实时离线检测，假如说翻船了呢。就像飞机上有黑夹子一样，就算飞机失事了只要找到那个黑夹子也可以推测以及判断飞机上发生了什么，这对我们都是有很大的用处的。我们中国作为一个大国，必须与时俱进，要实现军事与经济的共同发展。这里我们就简单的介绍我的数据采集系统，是以5509A芯片为模板的，从而实现对数据的收集和分析。86363

Abstract With the development of the Marine industy,the need for every navigation parameters timely collection and measurement and control, collection and measurement and from for data collection and analysis, data collection technology now become an important component。 Because of high-tech progress over the years, we demand has far outpaced the development of The Times, the rapid development of the photoelectric, all kinds of information we need to collect and summarize and encryption, but the domestic technology level in this spirit, the more did not involve deep instead of a multinational company monopoly of Europe, prices are also more expensive, simply said that we need to have our own technology。 Domestic involves the very shallow, but no further research in this aspect, I mainly use the sensor to simulate sea many kind of data, for example to research the static data of the ship Then the dynamic data。 Ship will encounter all sorts of car is on the sea, calm and tsunami and other weather data movement is not the same。 Here we want to realize real-time offline detection of ship, if say the ship capsizing。 Like there is a black clip on the plane, even when the plane crashed just find the black clip can speculate and judge what happened on the plane, which are of great use to us。 China as a big country, we must keep pace with The Times, to achieve the common development of the military and economic。 Here we have simple my data acquisition system is introduced in this paper, based on 5509 a chip as a template, so as to realize the data collection and analysis。
