Abstract

The invention relates to the technical field of circuit line and electronic line hardware, in particular to a positioning device for various short-circuit points of a circuit board card, which mainlycomprises an MCU, a signal source driving module, a power supply module, a signal interface conditioning and collecting module, a TFT touch color screen interface and a JTAG updating interface. The MCU is used for driving the DDS chip and the AD chip and processing the acquired data; an STM32F103ZET6 chip is selected and used as the MCU. The signal source driving module mainly comprises an external driving hardware interface and a DDS module; the signal source driving module is used for outputting an alternating current signal to realize digital-to-analog conversion; an AD9833 chip is selectedas the DDS module; the power supply module is used for converting an externally provided power supply into a low-voltage voltage through the power supply module so as to provide a stable and reliablepower supply for each functional module; on-line debugging and on-line program upgrading of the short-circuit positioning device system can be realized without disassembly, and great convenience is brought to upgrading of a user.
