In some embodiments, the humidity acquisition module 2 outputs a current signal (e.g., HMT 331), but in order to enable the multiplexing switch module 31c to be compatible with four-wire input signals under special conditions, the 24-to-1 switch circuit may include a plurality of four-pole switches, where the four-pole switches may be four-channel relays. Alternatively, the 24-choice 1 switching circuit may be a circuit formed by combining switching devices, so long as the humidity signal output by one humidity acquisition module 2 can be selectively output in the 24 humidity acquisition modules 2. As shown in fig. 4, the 24-to-1 switch circuit includes 25 four-knife switches (the number is not fully shown in fig. 4) each controlled by the control module 5, wherein the 24 humidity acquisition modules 2 are respectively connected to the remaining four-knife switches D one-to-one via 24 four-knife switches C thereof, and the four-knife switches D are also connected to the matrix switch module 32. Specifically, taking one of the four-knife switches C as an example, 4 input ends of the four-knife switch C are connected to 4 signal output ends of one of the humidity acquisition modules 2 one by one, 4 output ends of the four-knife switch C are connected to 4 input ends of the four-knife switch D one by one, and 4 output ends of the four-knife switch D are respectively connected to the 9 th port to the 12 th port of the matrix switch module 32.

The matrix switch module 32 is connected with the signal measurement module 4, the control module 5 and each multiplexing switch module 31, and is configured to receive the second control signal output by the control module 5, and input the acquisition signal output by one of the multiplexing switch modules 31 to the signal measurement module 4 according to the second control signal.

The matrix switch module 32 may be any conventional matrix switch module such as those manufactured by Pickering corporation of England, model number 40-521-021. As shown in fig. 4, the matrix switch module 32 may control the ports Y1 to Y8 of the matrix switch module 32 to be connected with any of the 1 st to 16 th ports of the matrix switch module 32 according to the second control signal, and it is easy to understand that the matrix switch module 32 may select the acquisition signals of 1 module from the 112 acquisition modules to be input to the signal measurement module 4 by cooperating with each multiplexing switch module 31.

In some embodiments, as shown in fig. 3, the acquisition device further comprises a programmable dc power supply 7 and an insulation test interface 8.

The programmable direct current power supply 7 is connected with the control module 5 and the matrix switch module 32, and the programmable direct current power supply 7 is used for outputting insulation test voltage according to the test signal output by the control module 5.

It should be noted that the programmable dc power supply 7 may be a switching power supply or a power supply module in the prior art.

The first end of the insulation test interface 8 is connected with the matrix switch module 32, and the second end of the insulation test interface 8 is used for connecting sensor cables of each temperature acquisition module 1 or each humidity acquisition module 2, so that two core wires of the sensor cables are controlled to be respectively communicated with the signal measurement module 4 and the program-controlled direct current power supply 7 through the matrix switch module 32.

It should be noted that, the sensor cable belongs to the existing equipment in the nuclear power plant, and is a communication bridge between the monitoring system and the temperature acquisition module 1 and the humidity acquisition module 2, so the reliability of the sensor cable is crucial for accurately monitoring the state of the containment vessel.

In the embodiment, on the basis of the matrix switch module 32 and the signal measurement module 4, the program-controlled direct current power supply 7 and the insulation test interface 8 are additionally arranged, so that the acquisition device also has the function of measuring the insulation performance of the sensor cable, the multifunction of the acquisition device is realized, and the fault checking processing time is reduced.

Specifically, as shown in fig. 5, the ports Y1 to Y8 of the matrix switch module 32 are respectively connected to the signal measurement module 4 and the programmable dc power supply 7, the 1 st to 4 th ports of the matrix switch module 32 are sequentially connected to the 2 nd to 5 th ports of the insulation test interface 8, the 1 st port of the insulation test interface 8 is grounded, and the 1 st port 3 of the matrix switch module 32 is connected to the 14 th port. The 2 nd port to the 5 th port of the insulation test interface 8 are respectively used for connecting 4 strands of core wires of the sensor cable, and the 1 st port of the insulation test interface 8 is used for connecting a shielding wire of the sensor cable.

It is easy to understand that the insulation performance testing principle between other core wires is the same, and only two corresponding core wires are controlled to be communicated with the signal measuring module 4 and the programmable direct current power supply 7 through the matrix switch module 32, which is not described herein.
