Design and Implementation on Analog Parameter Detection-circuits of AUV

检测控制电路是AUV检测控制单元的核心功能部件,其可靠性及性能的高低是AUV在水下任务成败的关键因素。文章提出了一种高精度多通道模拟参数检测电路设计方法,采用模拟隔离、多路选择及AD转换等电路实现多路模拟信号的实时采集,并集成了检测电路的测试与维护接口。该电路具有精度高、实时性强、隔离度高及可扩展性等特点,具有较好的应用前景。

As a core unit of the detection and control system of AUV,the performance of analog parameter Detection-circuits is one key factor in the success or failure about AUV＇s; underwater task. In this paper, an analog-data-acquisition circuit design method with multi-channel and high precision is introduced. This kind of circuit contains the different parts such as analog iso_ lating, multiplexer and AD transferring to achieve the purpose of real time gathering. And it also provides the interface of testing and maintenance. The circuit has the advantage of high precision,strong real time, high isolation degree and scalability, which has a good application prospect.
