项目摘要

The visual data storage tag was installed with a complementary metal-oxide-silicon charge-coupled device (CMOS CCD) that took 100 black-and-white pictures with 28000 pixels and stored them in a 1 mega-byte flush memory. The dimension of the tag is 92 x 40 x 28 mm^3, weighed ca. 200g in air and ca. 18g in water. It has an IrDA interface to transfer pictures to a personal computer. A prototype model has capacity to 100 m pressure and was timer-controlled to take pictures every one-hour. The magnetic field sensor accelerometer has a magneto-resistive effect (MR) sensor and three accelerometers in it. The MR sensor detects 3D magnetic field to transform into 3D direction data. All the signals of the MR sensors and the accelerometers were converted by A/D converter to 12-bit digital data controlled by a microprocessor inside the tag. The dimension is 54 mm 0 x 178 mm with ca.1500g in the air and ca. lOOOg in water. We conducted the first field tests of these tags attached to sea turtles in Thailand.Our final goal is to develop new tag types applicable to fish tracking. However, the prototypes of the tags were too large to be attached on fish. Therefore, we conducted the field test of the tags using adult sea turtles in the Sea Turtle Conservation Station belonging to the Department of Fisheries of Thai government. The Station was located at the Mannai Island in the Gulf of Thailand about 200 km eastward far from Bangkok. The station was founded in 1972 and was the center for the sea turtle research in the Gulf of Thailand.We also conducted to observe behaviors of turban shells and abalones using CCD-video camera system.

使用互补的金属氧化物 - 硅电荷耦合设备（CMOS CCD）安装了视觉数据存储标签，该设备（CMOS CCD）用28000个像素拍摄了100张黑白图片，并将它们存储在1兆字节的齐平齐平齐中。标签的尺寸为92 x 40 x 28 mm^3，称重为ca。 200克空气和CA。在水中18克。它具有将图片传输到个人计算机的IRDA接口。原型模型的容量为100 m，并且由计时器控制，每小时一次拍照。磁场传感器加速度计具有磁性抗性效果（MR）传感器和其中三个加速度计。 MR传感器检测到3D磁场以转换为3D方向数据。 MR传感器和加速度计的所有信号均由A/D转换器转换为由标签内部的微处理器控制的12位数字数据。尺寸为54毫米0 x 178毫米，空气中的1500g和Ca.1500g。在水中居住。我们对泰国海龟附带的这些标签进行了首次现场测试。我们的最终目标是开发适用于鱼类跟踪的新标签类型。但是，标签的原型太大，无法附着在鱼上。因此，我们在属于泰国政府渔业部的海龟保护站中使用成年海龟进行了标签测试。该车站位于泰国海湾的曼奈岛，距离曼谷远约200公里。该站成立于1972年，是泰国湾海龟研究中心。我们还进行了使用CCD-Video摄像机系统来观察Turban壳和鲍鱼的行为。
