该系统采用三块TCS230颜色传感器，监测轮船经过后海水的颜色变化的情况，数据采用就地处理，并运用改进型BP神经网络算法进行污染模式训练和模式识别。通过nRF401无线数字收发器，把污染识别的结果发送回监 视器，再通过字符和语音对识别结果进行报告。把轮船污染数据采集器安装在轮船尾部两侧进行实时监测，结果表明，监测速快，精确度高。-The system uses three TCS230 color sensor to monitor the ship through the water

A wireless sensor network (WSN) has important applications such as remote environmental monitoring and target tracking. This has been enabled by the availability, particularly in recent years, of sensors that are smaller, cheaper, and intelligent
