项目摘要

An appratus for the measurement of waves and currents in near-shore area was designed and fabricated. Through our experience of field measurements, we have had ideas that the instruments should be transportable by one or two persons and free from cables connecting them to recording or power supplying devices for safe and easy doployment, and that they should be unnecessary to open the lid of the case which houses the electronic unit to change recording media or battery. Moreover, each one of multiple apparatuses deployed in array must enable us to make synchronized measurements so that we can obtain simultaneous data, although they are completely separated electrically. The apparatus consists of the following units ; 1.measuring.unit, 2.power supplying unit, 3.recording unit, 4.control unit, 5.communication branch unit.The measuring unit is composed of a pressure gauge and an electromagnetic current meter. The measurable range of the EMCM is (]SY.+-。[)3.0m/s ((]SY.+-。[)1.5V). The signa … More ls are stored in memory together with the magnetic bearings taken with a compass, then they are written on PCMCIA flash ROM.The power source is a sealed lead acid battery with capacity of 12V25Ah. All parts of this unit are housed in a watertight and pressure resistant stainless steel case. Prior to station the apparatus, control data and measuring schedule are written on the ROM f the outside of the case without electrical contact through infra-red communication port using an optical data communication module which is connected to a portable computer. The measured data is also withdrawn by using the optical communication module. The transmission rate is 115Kbit/s and it takes about 13 minutes to transmit data of four megabytes. In order to obtain simultaneous data using multiple apparatuses, a multiple branch communication unit is used to transmit control signals and measuring schedule, and to start up counting clock pulses. Test results of the apparatuses at Fukiage beach were satisfactory. Less

根据我们的现场测量经验，我们设计并制造了一种用于测量近岸区域的波浪和海流的装置，我们认为该仪器应可由一两个人携带，并且无需连接记录或记录的电缆。电源装置必须能够安全、方便地部署，并且应该打开容纳电子单元的外壳的盖子来更换不必要的记录介质或电池。此外，阵列中部署的多个设备中的每一个都必须使我们能够同步。测量以便我们仪器由以下单元组成：1.测量单元，2.供电单元，3.记录单元，4.控制单元，5.通讯分支单元。单元由压力表和电磁电流表组成，EMCM的测量范围为(]SY.+-.[)3.0m/s。 ((]SY.+-.[)1.5V)。信号与指南针拍摄的磁力轴承一起存储在存储器中，然后写入 PCMCIA 闪存 ROM 上。电源是密封铅酸。容量为 12V25Ah 的电池。该装置的所有部件均装在防水耐压的不锈钢外壳内，在安装前，控制数据和测量计划均写入外壳外部的 ROM 中，无需通电。通过红外通讯端口与便携式计算机连接，测量数据也通过光通讯模块提取，传输速率为115Kbit/s，传输数据大约需要13分钟。为了使用多个设备同时传输数据，使用多分支通信单元来传输控制信号和测量时间表，并启动计数时钟脉冲，在吹上海滩的设备的测试结果令人满意。
