【摘要】 在海洋工程实验室现场数据采集过程中,由于测试点分散、实时性能要求较高、现场布线相对繁琐,提出一种基于WiFi的无线浪高数据采集系统;该系统主要由数据采集模块、单片机控制模块、无线WiFi模块以及上位机系统构成;采集的浪高信号经过电压偏置和低通滤波后由单片机控制器进行AD转换,然后通过无线WiFi模块输出数据;上位机系统通过无线AP点接收数据,再利用分析软件对数据进行分析和显示动态数据;在实验水池中,搭建由造波机、数据采集系统、无线接入点、上位机组成的实验系统来采集实时的浪高数据并验证系统数据传输的稳定性和数据通信的可靠性;通过实验证明,该系统可以实时采集浪高数据,具有传输速率快、可靠性高、实时性好的特点。更多还原

【Abstract】 In the progress of data types acquisition,as the geographically fragmented acquisition positions,high real-time performance demanding and complex industrial site,It is proposed a design of wave-height data gathering system based on WiFi.The system is mainly constructed of data acquisition unit,the main control unit,Wifi module and master station,wave-height data from AD converter will be stored into control circuit and outputted through WiFi module after processing by the master station.The PC in monitoring center receives wave-height data from wireless access point,after that,it will be displayed and analyzed by master station.In our lab,an experiment system consisted of the wave maker,collector,wireless access point and host is used to collect real-time wave-height data.It is also used to test the stability and the reliability of data communication of the system.The experiment suggests that the system have the advantages of high data transmission speed,high reliability,good real-time performance.更多还原
