自来水管道漏水定点探测系统中数据处理的实现

Realization of Data Processing in the Detecting System of the Fixation Leakage Point of the Tap Water Pipeline

在介绍相关渗漏检测仪器的工作原理和分析互相关理论的基础上,提出了一种基于数字处理器(DSP)TMS320VC5402芯片实现相关分析的方法,给出了仪器数据处理部分硬件设计电路和相应软件算法及流程图。实验证明:整个仪器的测量误差在0.5 m内,达到了预期要求。

By introducing the main principle of the leakage detecting instrument and analyzing the correlative theory, this paper put forward a method for realizing correlative analyses with one type of digital signal processor（DSP）chip TMS320VC_5402, and inla＇ouduced the hardware of data processed part of the instrument, the software arithmetic and the flow chart, After testing, the error of the whole instrument was known to be 0.5 meter,which has satisfied our expected need.
