摘要
设计一种多参数海洋环境检测装置,采用低功耗的ARM7系列的S3C44B0作为主处理器,采用I2C总线扩展多个智能传感器。为了提高模拟传感器的精度,采用数字滤波方法处理采集到的数据。在铱星通信过程中采用数据校验的方法和数据加密的方法,降低了数据的误码率和提高了数据的安全性。在实验室的环境下进行模拟实验,结果表明:系统工作可靠,并且模拟传感器具有很好的测量精度。
A set of multi-parameter marine environment testing devices is designed.Its processor is low consumption ARM7 processor S3C44B0.Several intelligent sensors are extended by the I2C bus.In order to improve the precision of the analog sensor,the digital filtering method is used to deal with the data collected.In iridium satellite communication process,data calibration method and data encryption method are used to reduce the false code rate probability and improve the data security.Simulation experiment is carried out in laboratory environment,the results show that the system works reliably,and analog sensor has satisfied precision.
