低功耗水下通信系统设计

Design of Low Power Underwater Equipment Communication System

设计了一种基于MSP430单片机和TMS320C55x系列DSP的低功耗水下通信系统,该系统中单片机一直处于上电状态,实时监测通信控制信号,在非通信时段DSP处于关机状态,单片机收到通信指令后,通过启动DSP电源启动DSP接收并解码通信信号,DSP完成通信并进行相关的指令操作后关机;单片机通过滑动相关方法检测通信控制信号,通过控制DSP电源启动关闭DSP,实验表明该系统能有效的降低功率,其中在通信时段占总时段1%的情况下,该系统能节省88.7%的功率。

The low power underwater equipment communication system is based on MSP430 MCU and the series of TMS320C55x DSP.The MCU is in power state and monitors the communication control signal persistently in the system.The DSP is closed in no communication time.Until the MCU receives communication instructions,the DSP is turned on after opening the power of DSP,then receives and decodes the signal.After the DSP accomplishes communication and operates instructions,the DSP is turned off.The MCU detects the communication control signal using sliding related method,and controls the power of DSP to start-up DSP.The experiments show that the system can effectively reduce the power,when the communication time is 1% of the total time,The system can save 88.7% of the power.
