摘要
介绍了一种基于电磁感应原理的电缆路径检测仪的硬件设计。利用发射设备向电缆中注入一定频率和强度的电流信号,根据电缆路径检测仪中的线圈所产生的感应电动势的强弱来判断电缆的具体位置,从而确定电缆的路径。该系统中以单片机和FPGA为核心,由信号处理电路、单片机系统、高速ADC等硬件电路模块组成。文中对该系统的工作原理作了详细描述。
A design of cable trace detector based on the principle of electromagnetic induction is presented in this paper. A current signal of certain frequency and intensity should be injected into this cable by a transmitting equipment, then, according to the induced electromotive force of the coils in the cable trace detector to determine the location of the cable. The MCU and FPGA is the core of this system, which also consists of signal processing circuit, ADO circuit module and so on. The operation principle of the system is described in detail.
