摘要：

水下信息处理平台是隔水管疲劳监测装置的神经中枢,控制疲劳参数检测,信号处理,数据发射,监测设备的休眠与启动等一系列流程.低功耗水下信息处理平台的硬件系统包括低功耗微处理机,高速数字信号处理器(DSP),多种传感器,信号调制与发送电路,电源及其他附件等.为了提高监测设备的服役期限,对"十一五"期间的低功耗水下信息处理平台进行优化设计,增加了存储模块,优化空间布局与程序流程,使得电路板面积大大缩小.优化后,水下信息处理平台的可靠性进一步增强,进而降低了隔水管监测系统的体积和质量,提高了其便捷性和适用性.

Abstract:

Underwater information processing platform is the nerve center of the riser fatigue monitoring device. It controls fatigue parameters detection, signal processing, data transmission, dormancy and initiation of the monitoring equipment and a series of processes. The hardware system of the low-power-consumption underwater information processing platform consists of low-power microprocessor, high-speed digital signal processor (DSP), a variety of sensors, signal modulation and transmission circuit, power supply and other accessories and so on. In order to improve the service period of the monitoring equipment, we optimize the design of the low-power underwater information processing platform during the "Eleventh Five-Year" period. We add storage modules and optimize spatial layout and program flow to greatly reduce the circuit board area. After optimization, the reliability of the underwater information processing platform is enhanced further. And then the volume and weight of the riser monitoring system are reduced and its convenience and applicability are improved.

Key words: marine oil and gas pipeline, deepwater riser, fatigue, low power consumption, underwater information processing platform, optimal design
