[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] like Figure 1 As shown, in a preferred embodiment, the detector neutron source test system provided by the present invention includes two parts: a signal measuring device 100 and a test operation device 200 .

[0047] The signal measurement device 100 is primarily used to provide the required high-voltage signal to the neutron detector and detect and display the detector's status signal. This allows for real-time detection and display of the detector's signal, enabling detector status monitoring. The test operation device 200 is primarily used to secure the neutron detector and enable remote operation of the neutron source, while also enabling mobile measurement of the neutron source assembly.

[0048] Specifically, such as Figure 1 As shown, in this embodiment, the signal measuring device 100 includes: a high-voltage output module 105 , a microprocessor 102 , a signal acquisition module 104 , a signal conversion module 103 and a measurement signal display module 101 .

[0049] The high-voltage output module 105 outputs a high-voltage signal and transmits it to a neutron detector mounted in the test operation device 200. Optionally, in this embodiment, the high-voltage output module 105 includes a digital-to-analog converter (DAC). The DAC is connected to the neutron detector mounted in the test operation device 200 and the microprocessor 102, respectively, and is configured to perform digital-to-analog conversion on the digital high-voltage signal generated by the microprocessor 102 before transmitting the analog high-voltage signal to the neutron detector. Specifically, the DAC receives the digital high-voltage signal generated by the microprocessor 102, performs digital-to-analog conversion on it, and transmits the resulting analog high-voltage signal to the neutron controller, thereby ensuring the required operating high voltage for the neutron detector. The high-voltage signal output by the high-voltage output module 105 can reach over 600V. It should be noted that different types of neutron detectors provide different high-voltage signals, meaning that the digital high-voltage signal generated by the microprocessor 102 can be adjusted based on the type of neutron detector. Furthermore, in this embodiment, the high-voltage signal output by the DAC has an output protection function to prevent the output high-voltage signal from exceeding the operating limit of the neutron detector, potentially damaging it.

[0050] The microprocessor 102 employed in the present invention can be any brand and model of microprocessor, such as a single-chip microcomputer or a DSP. The digital-to-analog converter employed in the present invention can be any brand and model of digital-to-analog converter, as long as it can convert digital signals into analog signals. For example, digital-to-analog converters such as the ZLC2541-18BSABT, SGM5347-8, UDACX088MS, and CBM97D79TQ can all be used.

[0051] The signal acquisition module 104 is connected to the neutron detector to acquire the signal generated by the neutron detector during the neutron source operation test to obtain the status signal of the neutron detector.

[0052] In this embodiment, the state signals collected by the signal collection module 104 include: a pulse signal and a current signal. The signal collection module 104 includes: a pulse collection circuit and a current collection circuit.

[0053] The pulse acquisition circuit is connected to the neutron detector to acquire the pulse signal generated by the neutron detector during the neutron source operation test to obtain the pulse signal of the neutron detector; the current acquisition circuit is connected to the neutron detector to acquire the current signal generated by the neutron detector during the neutron source operation test to obtain the current signal of the neutron detector.

[0054] In this embodiment, in order to ensure the stability and reliability of the collected pulse signal, the pulse signal collection circuit also amplifies the pulse signal after collecting the pulse signal. Figure 2 The circuit shown is implemented. Specifically, Figure 2 As shown, after the pulse signal is collected and input, it is first processed by RC filtering and then passed through the amplifier (such as Figure 2 The amplifier circuit composed of transistors VT1 and VT2 amplifies the pulse signal and then outputs it. This achieves the purpose of receiving the pulse signal stably.

[0055] In this embodiment, in order to ensure the stability and reliability of the collected current signal, the current collection circuit also amplifies the current signal after collecting the current signal. Figure 3 The circuit shown is implemented. Specifically, Figure 3 As shown, the current signal is collected and then passed through a logarithmic amplifier (such as Figure 3 The current is processed by VT1 in the circuit, amplified and then output to obtain a stable and reliable current signal.

[0056] To ensure that the current acquisition circuit has a relatively complete range, the resistance of the sampling resistor can be changed to achieve the measurement of currents of different magnitudes. Current signals of different magnitudes can be converted to voltage using precision resistors of different resistance values.

[0057] In this embodiment, signal conversion module 103 is connected to signal acquisition module 104 to convert the status signal into a standard signal. Specifically, signal conversion module 103 includes an analog-to-digital converter connected to the pulse acquisition circuit and the current acquisition circuit, respectively. The analog-to-digital converter performs analog-to-digital conversion on the pulse signal and the current signal, respectively, to obtain a digital signal of the pulse signal and a digital signal of the current signal.

[0058] Specifically, after receiving the pulse signal and the current signal, the analog-to-digital converter needs to perform analog-to-digital conversion on the pulse signal and the current signal to convert the analog signal generated by the neutron detector into a digital signal that can be recognized by the microprocessor 102 .

[0059] It should be noted that the analog-to-digital converter used in the present invention can be any existing brand and model, as long as it can convert analog signals into digital signals recognizable by the microprocessor 102. For example, analog-to-digital converters such as AD7656, AD7663, AD7606, and ADS8364 can all be used.

[0060] The microprocessor 102 is connected to the signal conversion module 103, processes the standard signal and sends the processed standard signal to the measurement signal display module 101. The standard signal is a pulse signal and a current signal. The current signal is at the pA and uA levels. Specifically, in this embodiment, the microprocessor 102 is mainly used to generate the high-voltage signal required by the neutron detector, and sends the generated high-voltage signal to the high-voltage output module 105, which is then sent to the neutron detector by the high-voltage output module 105. At the same time, the microprocessor 102 also performs corresponding processing on the pulse signal and current signal obtained after the conversion processing by the signal conversion module 103 and then sends them to the measurement signal display module 101. Specifically, the microprocessor 102 converts the received pulse signal and current signal into standard signals that can be accepted and displayed by the measurement signal display module 101 to ensure that the measurement signal display module 101 can normally display the pulse signal and current signal. The pulse signal can be converted into a voltage signal of 0-10V.

[0061] Optionally, in this embodiment, the microprocessor 102 may utilize, but is not limited to, existing single-chip microcomputers or embedded processors. Examples include 51 single-chip microcomputers, Am186 / 88, 386EX, SC-400, Power PC, 68000, MIPS, and ARM / StrongARM series embedded processors. It should be noted that in this embodiment, only the existing functions of the single-chip microcomputer or embedded processor are utilized, and no modifications are made to the internal computer programs.

[0062] The measurement signal display module 101 is connected to the microprocessor 102 and displays the standard signal processed by the microprocessor 102. In this embodiment, by setting the measurement signal display module 101 to display the status signal of the neutron detector in real time, visual monitoring of the neutron detector status signal is achieved.

[0063] Optionally, in this embodiment, the measurement signal display module 101 includes: a display screen, wherein the display screen includes but is not limited to an LCD display screen, an OLED display screen, a flexible display screen, and the like.

[0064] In this embodiment, the signal measuring device 100 can provide the high-voltage signal required by the neutron detector to the neutron detector fixed in the test operation device 200, and can also perform real-time detection of the status signal of the neutron detector, thereby realizing independent offline status detection of the neutron detector, thereby being able to discover quality defects of neutron detector spare parts in advance, improving the quality assurance of neutron detector spare parts, and avoiding unit degradation and unnecessary economic losses.

[0065] The test operation device 200 is used to fix the neutron detector and perform a neutron source operation test.

[0066] In this embodiment, the test operation device 200 includes: a detector fixing module 201. The detector fixing module 201 is used to fix the neutron detector. Specifically, Figure 4 As shown, the detector fixing module 201 includes two identical metal support frames, each of which includes: a base 2011 and a fixing portion 2012, wherein the base 2011 can be composed of a plurality of support columns and a chassis, the lower ends of the plurality of support columns are fixed to the chassis, and the upper ends of the plurality of support columns are connected to the fixing portion 2012, wherein the base 2011 and the fixing portion 2012 can be fixed by welding. Optionally, in this embodiment, in order to ensure that the neutron detector can be stably mounted on the detector fixing module 201, the bending radius of the fixing portion 2012 is the same as the radius of the neutron detector. The metal support frame can be made of, but not limited to, stainless steel, aluminum, iron and other materials, as long as it can support the neutron detector.

[0067] By providing the detector fixing module 201 , the neutron detector can be fixed during the neutron source test operation to avoid the risk of the neutron source falling.

[0068] Furthermore, the test operation device 200 also includes: an operation module 205; the operation module 205 is used to receive the operation action performed by the user and generate an operation signal according to the operation action. Optionally, in this embodiment, the operation module 205 includes: a mechanical rocker and a button. By setting the mechanical rocker, the forward and backward movement control of the test moving module 202 on the guide rail 207 can be achieved. In this embodiment, the button includes: a switch button 208 and a speed control button 209. Among them, the switch button 208 realizes the start and stop control, and the speed control button 209 is used to realize the forward and backward speed control of the test device. Among them, Figure 5 This is a schematic diagram (top view) of the use of the neutron source tank 2021 provided by the utility model without installation. Figure 6 It is a side view.

[0069] In this embodiment, by setting up the operation module 205, the operation module 205 generates a corresponding operation signal according to the operation of the experimenter, and the operation signal controls the forward and backward movement of the experiment movement module 202 (i.e., return movement), thereby realizing the control of the neutron source moving different distances.

[0070] Furthermore, if Figure 1 As shown, the test operation device 200 further includes: a wireless signal transceiver module, a test movement module 202 and a test signal display module 206 .

[0071] The wireless signal transceiver module receives the operation signal generated by the operation module 205 and transmits the operation signal to the test movement module 202, and returns the movement signal generated by the test movement module 202 during the neutron source operation test to the test signal display module 206; the test movement module 202 is connected to the wireless signal transceiver module, performs the movement operation according to the operation signal and generates the movement signal; the test signal display module 206 is connected to the wireless signal transceiver module, receives the movement signal and displays it.

[0072] By setting up the wireless signal transceiver module, it is possible to receive the operation signal generated by the remote operation module 205 , and it is also possible to receive the movement signal generated by the test movement module 202 and transmit it to the test signal display module 206 .

[0073] In this embodiment, Figure 1 As shown, the wireless signal transceiver module includes: a first wireless signal transceiver unit 203 and a second wireless signal transceiver unit 204 .

[0074] The first wireless signal transceiver unit 203 is connected to the operation module 205, and is used to receive the operation signal generated by the operation module 205 and transmit the operation signal to the second wireless signal transceiver unit 204, and receive the mobile signal returned by the second wireless signal transceiver unit 204; the second wireless signal transceiver unit 204 is connected to the test mobile module 202, and is used to receive the operation signal transmitted by the first wireless signal transceiver unit 203 and send the operation signal to the test mobile module 202, and transmit the mobile signal generated by the test mobile module 202 to the first wireless signal transceiver unit 203.

[0075] Specifically, the first wireless signal transceiver unit 203 and the second wireless signal transceiver unit 204 communicate via a TCP network or an IP network. The first wireless signal transceiver unit 203 and the second wireless signal transceiver unit 204 can both use an RS232 communication interface, a TTL communication interface, or a USB communication interface to achieve signal transmission. The baud rates of the RS232 communication interface, the TTL communication interface, and the USB communication interface are 4800 b / s, 9600 b / s, and 19200 b / s, respectively.

[0076] The test moving module 202 can be used to move the neutron source to different distances (ie, back and forth) to complete the neutron source test operation.

[0077] In this embodiment, the test mobile module 202 includes: a neutron source tank 2021, a neutron source mobile receiving unit and a neutron source transmission unit.

[0078] The neutron source tank 2021 is used to install the neutron source; the neutron source mobile receiving unit is connected to the wireless signal transceiver module, and is used to receive the operation signal transmitted by the wireless signal transceiver module and generate a driving signal according to the operation signal.

[0079] Furthermore, in this embodiment, the test mobile module 202 also includes: a neutron source transmission unit; the neutron source transmission unit is connected to the neutron source mobile receiving unit and the wireless signal transceiver module, and is used to perform a return movement operation according to the driving signal and return the generated movement signal to the wireless signal transceiver module.

[0080] In this embodiment, the neutron source tank 2021, the neutron source mobile receiving unit and the neutron source transmission unit are an integrated mobile device. The neutron source mobile receiving unit can receive the forward and backward control signals sent by the operating module 205. Figure 7 A schematic diagram of the use of the neutron source tank 2021 of the present invention after being fixed is shown.

[0081] In this embodiment, the neutron source tank 2021 is mainly used to carry the neutron source, which can not only meet the measurement requirements of the neutron detector, but also has a certain radiation protection function.

[0082] Optionally, the neutron source tank 2021 is made of stainless steel, and during the test, a cement wall is placed between the personnel and the neutron source tank 2021 to achieve neutron shielding. In this embodiment, the neutron source transmission unit includes: a driving mechanism, a pulley, and a pulley frame.

[0083] Among them, the pulley frame is made of aluminum alloy profiles. The hollow design not only ensures the strength of the platform, but also greatly reduces the mass of the platform. Fixings are provided on the guide rail 207 to prevent the device from rushing out of the track, and there are also fixings on both sides to ensure that the device moves in the same straight line and the accuracy of the test data. There is a ruler on the track to indicate the position of the device. In order to facilitate storage and transportation, the guide rail 207 is designed in a segmented mode, and the joints are connected by a snap-on method to ensure the firmness of the connection.

[0084] The test signal display module 206 can realize the display of the moving distance, so that the actual moving distance of the neutron source can be monitored to detect whether the actual moving distance of the neutron source is consistent with the required moving distance, thereby ensuring the accuracy of the measurement.

[0085] This novel detector neutron source test system provides independent offline status monitoring of neutron detectors. The operating module 205 enables remote operation of the neutron source, while the test signal display module 206 monitors the neutron source's position in real time. This significantly reduces the risk of neutron exposure from manually moving the neutron source while accurately monitoring its real-time location. Furthermore, the use of the detector fixing module 201 to secure the neutron source for mobile measurement reduces the risk of the source falling.
