本实施例中，所述电池仓1包括八组电池组，每组所述电池组均由双节ER34615M电芯组成。
需要说明的是，电池仓1还包括电池充放电管理模块、微控制器和显示器，电池充放电管理模块的输入端与电池组连接，电池充放电管理模块的输出端与微控制器的输入端连接，显示器与微控制器的输出端连接；电池充放电管理模块用于实时检测电池组的电压和电流，并将检测到的电池组的电压和电流发送至微控制器，微控制器再将接收到的电池组的电压和电流通过显示器进行显示。
本发明提供了一种新型潜标数据采集***，包括电池仓1、主控处理器2、GPS接收机3、千兆以太网接口模块4和至少一个数据采集板，采用电池仓1为各用电模块进行供电，每个数据采集板均与主控处理器2连接，每个数据采集板的水听传感器51用于实时检测声波信号，并将检测到的模拟声波信号通过前端驱动电路52进行放大后输入至AD转换电路53，由AD转换电路53转换为数字声波信号后输入至FPGA56，再由 FPGA56传输至ARM处理器57，由ARM处理器57存储至存储模块58中，完成了每个数据采集板的采集过程；且每个数据采集板的ARM处理器57还可将接收到的数字声波信号发送至主控处理器2，由主控处理器2通过千兆以太网接口模块4传输至上位机6，使得上位机6根据接收到的数字声波信号对各数据采集板进行监控，确保各数据采集板正常工作。由此可知，本发明是将采集到的模拟声波信号转换为数字声波信号后就近保存至SD卡，避免采集数据丢失；还将数字采集数据通过千兆以太网接口模块4传输至上位机6，降低了对采集数据的衰减和干扰，提高了潜标数据采集***的采集性能；另外，GPS接收机3用于提供高精度的授时信息，并将授时信息发送至主控处理器2，由主控处理器2最终发送至每个数据采集板的FPGA56，每个数据采集板的FPGA56根据时钟模块54和接收到的授时信息设置DA转换电路55的输出电压，从而调整时钟模块的振荡频率，达到对时钟校准的目的，实现了每个数据采集板的同步触发输入和同步触发输出，即实现了整个潜标数据采集***的同步采集和控制。
以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。对这些实施例的多种修改对本领域的专业技术人员来说是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
