[0068] Before describing the technical solutions provided in the embodiments of this application, in order to facilitate understanding of the embodiments of this application, this application first specifically explains the problems existing in the related technologies:

[0069] A detector is an instrument used to collect radioactive elements in the surrounding air.

[0070] The ability of a detector to accurately output signals that meet the requirements of a radioactive material monitoring system has become a key factor in evaluating the performance of such systems. Different models of radioactive material monitoring systems require detectors with different output signal types. However, when verifying detectors with different signal types, related technologies cannot quickly and accurately acquire the detector's output signals, leading to cumbersome overall testing procedures and long testing times.

[0071] Based on this, embodiments of this application provide a multi-channel multi-track analysis circuit and analysis device, which can quickly and accurately acquire different types of signals output by the detector, saving test time and improving test efficiency.

[0072] The multi-channel multi-track analysis circuit provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0073] Figure 1 This is a schematic diagram of a multi-channel multichannel analysis circuit 100 provided in an embodiment of this application. The multi-channel multichannel analysis circuit 100 is used to acquire signals output by the detector 200, such as... Figure 1 As shown, the multi-channel multichannel analysis circuit 100 includes at least one single-channel multichannel analysis circuit 110 and a multichannel acquisition module 120.

[0074] The detector 200 can be a gamma detector or a neutron detector. The multi-channel multi-channel analysis circuit 100 can acquire the signal output by the gamma detector or the signal output by the neutron detector.

[0075] The input terminal of the single-channel multichannel analysis circuit 110 is electrically connected to the output terminal of the detector 200.

[0076] The input terminal of the multichannel acquisition module 120 is electrically connected to the output terminal of the single-channel multichannel analysis circuit 110, and the output terminal of the multichannel acquisition module 120 is electrically connected to the industrial control computer 300. The multichannel acquisition module 120 is used to convert the signal output by the single-channel multichannel analysis circuit 110 into a digital signal and transmit it to the industrial control computer 300.

[0077] The single-channel multi-channel analysis circuit 110 includes a gating module 10 and an operational amplifier circuit 20.

[0078] The input terminal of the gating module 10 is electrically connected to the output terminal of the detector 200.

[0079] The non-inverting input terminal of the operational amplifier circuit 20 is electrically connected to the first output terminal of the gating module 10, and the inverting input terminal of the operational amplifier circuit 20 is electrically connected to the second output terminal of the gating module 10.

[0080] The operational amplifier circuit 20 is used to amplify the signal output by the detector 200 before outputting it.

[0081] The gating module 10 is used to transmit the signal output by the detector 200 to the non-inverting input of the operational amplifier circuit 20, or to transmit the signal output by the detector 200 to the inverting input of the operational amplifier circuit 20. The gating module 10 can be implemented by selectively soldering a 0Ω resistor, jumper wire, switching device, etc.

[0082] It should be noted that, in the embodiments of this application, the multi-channel multichannel analysis circuit can be referred to as a multi-channel multichannel analysis circuit, and the single-channel multichannel analysis circuit can be referred to as a single-channel multichannel analysis circuit.

[0083] According to the multi-channel multichannel analysis circuit 100 provided in the embodiments of this application, the multi-channel multichannel analysis circuit 100 can acquire positive or negative signals output by the detector 200. The multi-channel multichannel analysis circuit 100 includes at least one single-channel multichannel analysis circuit 110 and a multichannel acquisition module 120. The input terminal of the single-channel multichannel analysis circuit 110 is electrically connected to the output terminal of the detector 200. The input terminal of the multichannel acquisition module 120 is electrically connected to the output terminal of the single-channel multichannel analysis circuit 110, and the output terminal of the multichannel acquisition module 120 is electrically connected to an industrial control computer 300. The multichannel acquisition module 120 is used to convert the signal output by the single-channel multichannel analysis circuit 110 into a digital signal and transmit it to the industrial control computer 300. The single-channel multichannel analysis circuit 110 includes a gating module 10 and an operational amplifier circuit 20. The input terminal of the gating module 10 serves as the input terminal of the single-channel multi-channel analysis circuit 110, enabling it to acquire the signal output by the detector 200. The gating module 10 can transmit the signal output by the detector 200 to the non-inverting input terminal of the operational amplifier circuit 20, or it can transmit the signal output by the detector 200 to the inverting input terminal of the operational amplifier circuit 20. The gating module 10 allows for flexible selection of whether the signal output by the detector 200 is transmitted to the non-inverting or inverting input terminal of the operational amplifier circuit 20. For example, a positive signal can be transmitted to the non-inverting input terminal of the operational amplifier circuit 20, or a negative signal can be transmitted to the inverting input terminal of the operational amplifier circuit 20, providing more options and flexibility for signal processing and adapting to different signal types output by the detector 200. The non-inverting input of the operational amplifier circuit 20 is electrically connected to the first output of the gating module 10, and the inverting input is electrically connected to the second output of the gating module 10. The output of the operational amplifier circuit 20 serves as the output of the single-channel multichannel analysis circuit 110. The operational amplifier circuit 20 amplifies the signal output by the detector 200 before outputting it. The operational amplifier circuit 20 amplifies the signal output by the detector 200, helping to enhance the signal strength and making it easier for the subsequent industrial control computer 300 to recognize and analyze, thus improving the accuracy and reliability of the test. In this embodiment, the multichannel multichannel analysis circuit 100 includes a multichannel acquisition module 120 and at least one single-channel multichannel analysis circuit 110, which can be expanded into multiple single-channel multichannel analysis circuits 110. It has multichannel processing capabilities, enabling it to quickly and accurately acquire different types of signals output by the detector, saving test time and improving test efficiency.

[0084] Figure 2-A This is another schematic diagram of the structure of the multi-channel multi-track analysis circuit provided in the embodiments of this application.

[0085] In some embodiments, such as Figure 2-A As shown, the gating module 10 includes a first switch 01 and a second switch 02.

[0086] The first end of the first switch 01 serves as the input end of the gating module 10, the second end of the first switch 01 is electrically connected to the non-inverting input end of the operational amplifier circuit 20, and the control end of the first switch 01 is electrically connected to the first control signal end.

[0087] The first terminal of the second switch 02 is electrically connected to the first terminal of the first switch 01, the second terminal of the second switch 02 is electrically connected to the inverting input terminal of the operational amplifier circuit 20, and the control terminal of the second switch 02 is electrically connected to the second control signal terminal.

[0088] At any given moment, one of the first switch 01 and the second switch 02 is in the ON state, and the other switch is in the OFF state.

[0089] This embodiment of the application achieves complementary control of the first switch 01 and the second switch 02, that is, only one switch is turned on at any given time. This enables the selection module 10 to flexibly switch the output signal of the detector to the non-inverting or inverting input terminal of the operational amplifier circuit 20. This can quickly and accurately adapt to and collect different types of signals output by the detector, saving test time and improving test efficiency.

[0090] Figure 2-B This is another schematic diagram of the structure of the multi-channel multi-track analysis circuit provided in the embodiments of this application.

[0091] In some embodiments, such as Figure 2-B As shown, the first control signal terminal and the second control signal terminal are the same control signal terminal.

[0092] The first switch 01 and the second switch 02 have different conduction conditions. For example, the first switch 01 is a P-type transistor, and the second switch 02 is an N-type transistor.

[0093] The embodiments of this application simplify the circuit structure by using a first switch 01 and a second switch 02 with different conduction conditions, while still maintaining the flexibility to select the in-phase or out-of-phase input terminals of the signal input operational amplifier circuit, thus improving the simplicity of the circuit design.

[0094] Figure 2-C This is another schematic diagram of the structure of the multi-channel multi-track analysis circuit provided in the embodiments of this application.

[0095] In some embodiments, such as Figure 2-C As shown, the single-channel multichannel analysis circuit 120 includes a first voltage comparator 121, a second voltage comparator 122, and a master controller 123.

[0096] The non-inverting input terminal of the first voltage comparator 121 is electrically connected to the first voltage terminal, and the inverting input terminal of the first voltage comparator 121 is electrically connected to the output terminal of the detector, wherein the first voltage terminal is configured with a first voltage.

[0097] The inverting input terminal of the second voltage comparator 122 is electrically connected to the second voltage terminal, and the non-inverting input terminal of the second voltage comparator 122 is electrically connected to the output terminal of the detector. The second voltage terminal is configured with a second voltage.

[0098] The first input terminal of the main controller 123 is electrically connected to the output terminal of the first voltage comparator 121, the second input terminal of the main controller is electrically connected to the output terminal of the second voltage comparator 122, and the control signal output terminal of the main controller 123 serves as the control signal terminal.

[0099] The first voltage terminal can be configured with a first voltage (e.g., 0V, 0.5V, etc.). The inverting input of the first voltage comparator 121 is electrically connected to the output of the detector 200. The first voltage comparator 121 is configured to detect when the signal output by the detector 200 is greater than the first voltage (e.g., 0V, 0.5V, etc.). In other words, the first voltage comparator 121 is configured to detect a positive signal output by the detector 200. Similarly, the inverting input of the second voltage comparator 122 is electrically connected to the second voltage terminal, which is configured with a second voltage (e.g., 0V, -0.5V, etc.). The non-inverting input of the second voltage comparator 122 is electrically connected to the output of the detector 200. The second voltage comparator 122 is configured to detect when the signal output by the detector 200 is less than the second voltage (e.g., 0V, -0.5V, etc.). In other words, the second voltage comparator 122 is configured to detect a negative signal output by the detector 200.

[0100] Specifically, when the first voltage comparator 121 detects that the signal output by the detector 200 is greater than the first voltage (e.g., 0V, 0.5V, etc.), the control signal output terminal of the main controller 123 continuously outputs a control signal to control the first switch 01 to be turned on and the second switch 02 to be turned off. This transmits the positive signal output by the detector 200 to the non-inverting input terminal of the operational amplifier circuit 20, so that the non-inverting operational amplifier circuit in the operational amplifier circuit 20 can function. Alternatively, when the second voltage comparator 122 detects that the signal output by the detector 200 is less than the second voltage (e.g., 0V, -0.5V, etc.), the control signal output terminal of the main controller 123 continuously outputs a control signal to control the first switch 01 to be turned off and the second switch 02 to be turned on. This transmits the negative signal output by the detector 200 to the inverting input terminal of the operational amplifier circuit 20, so that the inverting operational amplifier circuit in the operational amplifier circuit 20 can function.

[0101] In this embodiment, the multi-channel acquisition module 120 can detect the signal type (positive or negative signal type) output by the detector 200 through the first voltage comparator 121 and the second voltage comparator 122, and output control signals through the main controller 123 to flexibly control the conduction and cutoff of the first switch 01 and the second switch 02. It can flexibly select whether the non-inverting operational amplifier circuit or the inverting operational amplifier circuit in the operational amplifier circuit 20 is active. Therefore, it can automatically switch the working mode of the operational amplifier circuit 20 according to the output signal type of the detector 200, and can quickly and accurately acquire different types of signals output by the detector, saving test time and improving test efficiency.

[0102] In one example, see Figure 2-C The operational amplifier circuit 20 shown includes a non-inverting operational amplifier circuit and an inverting operational amplifier circuit. A first switch 01 is electrically connected to the non-inverting input terminal of the non-inverting operational amplifier circuit, and a second switch 02 is electrically connected to the inverting input terminal of the inverting operational amplifier circuit. The inventors discovered that since only one of the first switch 01 and the second switch 02 is active at any given time—meaning only one of the non-inverting and inverting operational amplifier circuits in the operational amplifier circuit 20 is active at any given time—the output terminals of the non-inverting and inverting operational amplifier circuits in the operational amplifier circuit 20 can be electrically connected as the output terminal of the operational amplifier circuit 20. This reduces wiring and saves costs.

[0103] In another example, the operational amplifier circuit 20 may further include a first impedance matching circuit and a second impedance matching circuit. The first switch 01 is electrically connected to the non-inverting input terminal of the non-inverting operational amplifier circuit in the operational amplifier circuit 20 via the first impedance matching circuit, and the second switch 02 is electrically connected to the inverting input terminal of the inverting operational amplifier circuit in the operational amplifier circuit 20 via the second impedance matching circuit. The first impedance matching circuit can be found in the appendix. Figure 7 The circuit connection structure of the first capacitor 31, the first sliding rheostat 32, the third resistor 33, and the fourth resistor 34 in the figure, and the second impedance matching circuit can be found in the appendix. Figure 7 The circuit connection structure of the second capacitor 41, the second sliding rheostat 42 and the ninth resistor 43 is not described in detail here.

[0104] Figure 3 This is another schematic diagram of the structure of the multi-channel multi-track analysis circuit provided in the embodiments of this application.

[0105] In some embodiments, such as Figure 3 As shown, the gating module 10 may include a first resistor 11.

[0106] The first pin of the first resistor 11 serves as the input terminal of the gating module 10, and the second pin of the first resistor 11 serves as the first output terminal of the gating module 10. The first resistor 11 is used to transmit the positive signal output by the detector 200 to the non-inverting input terminal of the operational amplifier circuit 20.

[0107] In this embodiment, when the detector 200 outputs a positive signal, the positive signal output by the detector 200 is transmitted to the non-inverting input terminal of the operational amplifier circuit 20 by welding the first resistor 11, so as to subsequently configure the operational amplifier circuit 20 as a non-inverting operational amplifier circuit, thereby achieving precise signal selection and enabling the acquisition function of the positive signal output by the detector 200.

[0108] In one example, the first resistor 11 can have a resistance of 0Ω, which can serve as a circuit connection, and using a 0Ω resistor is more reliable than using a jumper.

[0109] In some embodiments, see [link to relevant documentation]. Figure 3 The operational amplifier circuit 20 may include a first operational amplifier 21 and a second resistor 22.

[0110] The non-inverting input of the first operational amplifier 21 is electrically connected to the second pin of the first resistor 11.

[0111] The first pin of the second resistor 22 is electrically connected to the inverting input terminal of the first operational amplifier 21, and the second pin of the second resistor 22 is electrically connected to the output terminal of the first operational amplifier 21.

[0112] The second resistor 22 can be 1KΩ.

[0113] In this embodiment, the operational amplifier circuit 20 forms a feedback path through the connection of the first operational amplifier 21 and the second resistor 22, thereby realizing the feedback amplification of the signal. The non-inverting input terminal of the first operational amplifier 21 directly receives the signal from the gating module 10, so it can receive the positive signal output by the detector 200 and amplify the positive signal in the same phase. This achieves accurate acquisition and amplification of the positive signal output by the detector 200, improving the signal processing efficiency and flexibility.

At this time, the first knob RSW1 and the second knob RSW2 can be fixed as the measurement reference, and then the other detectors 200 to be verified can be tested. If the positive signal and the negative signal output by the detector 200 to be verified can also overlap, it means that the detector 200 to be verified is qualified.
