摘要
为了实现水下多传感器节点系统的电磁场信号采集、处理以及处理结果的长距离传输,提出了1种基于定点DSP芯片TMS320F2812的水下电磁场信号采集与处理单元设计方案,以该芯片作为单元的核心来完成信号采集与处理,并将处理结果通过CAN总线网络进行传输。文中给出了相应的硬件实现和软件设计,其中对DSP的信号处理方法与CAN接口配置做出了较为详细的介绍。基于该方案的信号采集与处理单元已经研制完成,并在系统原理样机中得到成功应用。试验结果表明,该单元在系统中工作正常、性能稳定。
In order to realize underwater electromagnetic signal acquisition and processing and transmitting result for long distance in multi-sensor nodes system,the paper presents a design scheme based on a fixed-point DSP-TMS320F2812 which as kernel of the unit can complete signal collecting and processing,and transmitting the results through CAN bus.The hardware realization and software design and also the CAN interface configuration are introduced.The unit which is applied to the model machine has completed,and the experiment followed indicates that it works with better performance and stabilization.
