AI Technical Summary
Testing electronic circuit boards in nuclear instrumentation systems of nuclear power plants is difficult. Ordinary testing instruments cannot perform invasive inspections, and electronic circuit boards cannot operate offline when separated from their original host equipment, resulting in low efficiency in equipment fault detection and affecting the safe operation of the unit.
Design a testing device for electronic circuit boards of nuclear instrumentation systems in nuclear power plants, including a host computer, a signal measurement and control unit, a micro-current source, a signal distribution unit, a signal conversion unit, and a power distribution unit. Through these units, rapid and accurate board-level testing and fault circuit range location of various circuit boards in nuclear instrumentation systems can be achieved.
It enables comprehensive measurement of electronic boards in nuclear instrumentation systems, improves equipment performance verification and maintenance capabilities, solves the problem of electronic boards being unable to operate offline, and provides an effective approach for fault analysis.
