Embodiment 1
[0025] see figure 1 with figure 2 , a kind of million-kilowatt-level nuclear power plant radiation monitoring system processing unit test platform proposed in embodiment one includes a test seat 10 and a PCB extension board 20 vertically fixed on the test seat; The vertical control board guide rail 11 of the extension board, the measurement board guide rail 12 and the energy spectrum analysis board guide rail 13, the control board connector 21 and the control board test hole 24 electrically connected to each other are provided on the PCB extension board 20, and the measurement of the mutual electrical connection Board connector 22 and measurement board test hole 25, and the energy spectrum analysis board connector 23 and the energy spectrum analysis board test hole 26 that are electrically connected to each other; The inner end of described control board connector 21 and control board guide rail 11 is opposite and vertical, makes radioactivity The control board (not shown) o...
Embodiment 2
[0029] Embodiment 2 also includes a shielded cable (not shown) on the basis of Embodiment 1. The shielded cable includes a control board connection wire, a measurement board connection wire and an energy spectrum analysis board connection wire. One end of the control board connection wire It is electrically connected to the control board connector 21, and the other end is electrically connected to the control board interface on the processing unit of the radiation monitoring system; one end of the measurement board connection line is electrically connected to the measurement board connector 22, and the other end is connected to the radiation monitoring system processing unit. The measurement board interface on the unit is electrically connected; one end of the energy spectrum analysis board connection line is electrically connected to the energy spectrum analysis board connector 23, and the other end is electrically connected to the energy spectrum analysis board interface on th...
Embodiment 3
[0032] Embodiment 3 further refines the design on the basis of Embodiment 1 or Embodiment 2. Specifically, please continue to figure 1 with figure 2, the test base 10 is fixed with uprights 14 on the left and right sides perpendicular to it, and the PCB extension plate 20 is fixed between the uprights 14 on the left and right sides; the upper and lower ends of the PCB extension plate 20 are fixed with beams 15, and The beams 15 at both ends are respectively fixed to the upper and lower ends of the columns 14 on the left and right sides; the middle parts of the beams 15 at the upper and lower ends are fixedly connected with vertical beams 16 .
