[0053] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0054] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0055] This utility model provides a radiation detection device. Figure 1 This is a schematic diagram of a radiation detection device provided in an embodiment of the present invention. (Reference) Figure 1 The radiation detection device includes a signal control module 1, a detection module 2, and an industrial control module 3. The signal control module 1 is connected to the object under test (AUT) 4 and outputs current to AUT 4 after a set delay, causing AUT 4 to emit a radiation signal. The detection module 2 is connected to the signal control module 1 and detects the radiation signal emitted by AUT 4 in at least one set wavelength band, inputting the detection data into the signal control module 1. The industrial control module 3 is connected to the signal control module 1 and receives the detection data after a set delay, converting it into radiation intensity information.

[0056] The signal control module 1 provides current to the object under test (DUT) 4. When a certain current is input, DUT 4 emits radiation. The detection module 2 receives the radiation signal emitted by DUT 4 and generates detection data. For example, the radiation signal emitted by DUT 4 is a full-band radiation signal. In actual testing, the detection module 2 can select a radiation signal within a set band to reflect the radiation intensity information. For example, a radiation signal with a wavelength in the range of 3-5 μm, or a radiation signal with a wavelength in the range of 8-14 μm, can be selected.

[0057] After the detection module 2 generates the detection data, the detection data can be input into the industrial control module 3 through the signal control module 1, and the industrial control module 3 converts the detection data into radiation intensity information, which is the radiation intensity emitted by the object under test 4.

[0058] To prevent the industrial control module 3 from failing to receive the detection data sent by the detection module 2 in a timely manner when the object under test 4 emits a radiation signal, a delay time can be set through the signal control module 1. This allows the signal control module 1 to output current to the object under test 4 after the set delay time. Setting the delay time also provides sufficient time for personnel to move away from the area where the object under test 4 is located, ensuring high safety. Simultaneously, the signal control module 1 can input the delay time into the industrial control module 3, enabling the industrial control module 3 to receive the detection data promptly after the set delay time. This configuration ensures the consistency between the detection data received by the industrial control module 3 and the radiation signal emitted by the object under test 4, preventing the industrial control module 3 from missing the detection data sent by the detection module 2.

[0059] The technical solution provided by this utility model embodiment sets a delay time through a signal control module, and outputs current to the object under test after the delay time, allowing relevant personnel to stay away from radiation areas, thus providing a high level of safety. The industrial control module can also receive detection data according to the delay time, improving the consistency between the industrial control module's data sampling time and the time when the object under test emits a radiation signal, avoiding situations where the industrial control module fails to collect detection data, thereby improving the accuracy of radiation detection.

[0060] Figure 2 A schematic diagram of another radiation detection device provided in an embodiment of this utility model. (Reference) Figure 2Based on the above embodiments, optionally, the signal control module 1 includes: a transmission unit 11, a delay counting unit 12, a multiplex simulation unit 13, and a current output unit 14. The delay counting unit 12 is connected to the transmission unit 11, which is also connected between the detection module 2 and the industrial control module 3. The delay counting unit 12 is used to enable the transmission unit 11 to output a signal after a set delay time. The transmission unit 11 includes at least one signal output port. The multiplex simulation unit 13 is connected to the current output unit 14 and is used to provide a level signal to the current output unit 14. The current output unit 14 includes multiple current output ports 141 and is used to control one current output port 141 to output current to the object under test according to the level signal.

[0061] The multiplexed analog unit 13 may include a multiplexed analog switch for outputting multiple level signals. For example, the multiplexed analog switch can output 16 level signals, applicable to a current output unit 14 with 16 current output ports 141. The current output unit 14 may include a current source. Each current output port 141 can be connected to a device under test (DUT) 4; therefore, using this multiplexed analog switch, 16 DUTs 4 can be tested with a single connection.

[0062] The delay counting unit 12 may include a counter. After a set delay time, the delay counting unit 12 controls the multiplex analog unit 13 to output a level signal, so that the current output unit 14 controls a current output port 141 to output current according to the level signal, thereby causing the test object 4 connected to the current output port 141 to emit a radiation signal.

[0063] This embodiment of the invention, by setting up a multi-channel simulation unit, can realize the output of multi-channel level signals to control the current output port to output current. Furthermore, by setting up a delay counting unit, it achieves delayed output of current, which has high reliability and safety, improves the consistency between the data sampling time of the industrial control module and the time when the measured object emits radiation signals, and enhances the accuracy of radiation detection.

[0064] Continue to refer to Figure 2 Based on the above embodiments, optionally, the signal control module 1 includes a trigger delay time selection knob connected to the delay counting unit 12. The trigger delay time selection knob generates a pulse signal by rotation, and the delay counting unit 12 adjusts the delay setting time according to the pulse signal.

[0065] The trigger delay time selection knob can be located outside the signal control module 1. By rotating the trigger delay time selection knob, a pulse signal is generated, and the delay counting unit 12 can count and process the pulse signal.

[0066] For example, when the trigger delay time selection knob is rotated clockwise, a positive pulse is generated. Upon receiving these pulses, the delay counting unit 12 increments the time value according to a preset rule. For instance, if the delay counting unit 12 counts in seconds, it increments the time by one second for each received pulse. Conversely, when the trigger delay time selection knob is rotated counterclockwise, a reverse pulse is generated, and the delay counting unit 12 decrements the time value accordingly. The delay counting unit 12 can also be connected to a digital display for numerical display, allowing the user to intuitively see the adjusted time.

[0067] Continue to refer to Figure 2 Based on the above embodiments, optionally, the current output unit 14 further includes at least two first current output ports; the signal control module 1 further includes an ignition position selection knob. One first current output port is connected to a test object 4. The ignition position selection knob is connected to the transmission unit 11, and the ignition position selection knob rotates the first current output port of the current output unit 14.

[0068] Each of the first current output ports can output the same current. By controlling the output current of different first current output ports, radiation detection can be performed on different test objects 4.

[0069] The ignition position selection knob can be used to select the first current output port of the current output unit 14. For example, the ignition position selection knob may include a single-pole multi-position switch; by rotating the ignition position selection knob, different first current output ports of the current output unit 14 can be connected. The circuit simulation unit 13 may also be connected to a digital tube for numerical display, allowing the user to intuitively see which first current output port is outputting current.

[0070] Figure 3 This is a schematic diagram of a detection module provided in an embodiment of the present utility model. (In conjunction with...) Figure 2 and Figure 3Based on the above embodiments, optionally, the detection module 2 includes: an optical unit 21, a modulation unit 22, a first acquisition unit 23, a first processing unit 24, a second acquisition unit 25, a second processing unit 26, and a control unit 27. The optical unit 21 receives the radiation signal emitted by the object under test 4 and filters out radiation signals outside a set wavelength band. The modulation unit 22 is connected to the optical unit 21 and modulates the radiation signal within the set wavelength band. The first acquisition unit 23 is connected to the modulation unit 22 and acquires the radiation signal within the first set wavelength band and converts it into first detection data. The first processing unit 24 is connected to the first acquisition unit 23 and amplifies and filters the first detection data. The second acquisition unit 25 is connected to the modulation unit 22 and acquires the radiation signal within the second set wavelength band and converts it into second detection data; wherein the second set wavelength band does not overlap with the first set wavelength band. The second processing unit 26 is connected to the second acquisition unit 25 and amplifies and filters the second detection data. The control unit 27 is connected to the first processing unit 24 and the second processing unit 26, and is also connected to the signal control module 1 through the first communication interface 28 and the second communication interface 29. The control unit 27 outputs the first detection data to the signal control module 1 through the first communication interface 28 and the second detection data to the signal control module 1 through the second communication interface 29.

[0071] In the detection of radiation signals, the radiation intensity emitted by the object under test 4 can be reflected by the radiation signals in the 3-5μm and 8-14μm bands. The radiation signals can be infrared radiation signals. The optical unit 21 can filter out all radiation signals outside these two bands and input the radiation signals within the two bands into the modulation unit 22.

[0072] The modulation unit 22 can modulate the radiated signal onto a high-frequency carrier wave and utilize higher frequency resources to increase the bandwidth of the radiated signal transmission, thereby improving the efficiency of information transmission and enabling the transmission of more data. The first acquisition unit 23 can be used to acquire the radiated signal in the 3-5μm band and convert it into first detection data. The second acquisition unit 25 can be used to acquire the radiated signal in the 8-14μm band and convert it into second detection data. Exemplarily, the first and second detection data can be analog signals.

[0073] After signal conversion, the first processing unit 24 can amplify and filter the first detection data, and the second processing unit 26 can amplify and filter the second detection data. The first detection data is output through the first communication interface 28, and the second detection data is output through the second communication interface 29. For example, both the first processing unit 24 and the second processing unit 26 may include a filter and a signal amplifier.

[0074] The signal control module 1 can input the first detection data and the second detection data into the industrial control module 3, and the industrial control module 3 converts them into radiation intensity information in the 3-5μm band and radiation intensity information in the 8-14μm band. This radiation intensity information corresponds to the radiation intensity emitted by the object under test 4. For example, the industrial control module 3 may also include a display for displaying the radiation intensity.

[0075] Figure 4 A schematic diagram of another radiation detection device provided as an embodiment of this utility model. (Reference) Figure 4 Based on the above embodiments, optionally, the radiation detection device further includes: a switch module 5, connected between the current output port 141 and the object under test 4, for conducting or cutting off the output current of the current output port 141.

[0076] To prevent the signal control module 1 from erroneously outputting current and causing the tested object 4 to generate radiation, a switch module 5 can be set between the current output port 141 and the tested object 4. When the signal control module 1 is not needed, the switch module 5 can be turned off, so that the current output port 141 cannot output current.

[0077] This embodiment of the utility model achieves control over the output current of the current output port 141 by setting the switch module 5, which has a better control effect and improves the safety of the radiation detection device.

[0078] Continue to refer to Figure 4 Based on the above embodiments, optionally, the radiation detection device further includes: a calibration module 6, used to emit a calibration radiation signal with a fixed radiation intensity; a detection module 2, used to detect the calibration radiation signal and convert it into a calibration analog signal input signal control module 1; and an industrial control module 3, used to convert the calibration analog signal into calibration radiation intensity information.

[0079] The calibration module 6 may include a blackbody that radiates a calibration radiation signal with a fixed intensity. The detection module 2 detects this calibration radiation signal. If the calibration radiation intensity information detected by the industrial control module 3 does not match the actual calibration radiation signal radiated by the blackbody, it indicates that the calibration analog signal converted by the detection module 2 has a certain error. Therefore, the accuracy of the radiation detection device can be calibrated by adjusting the detection module 2. For example, the detection data generated by the detection module 2 may include a voltage signal, and the industrial control module 3 can calculate the radiation intensity information by converting the voltage signal.

[0080] Continue to refer to Figure 4Based on the above embodiments, optionally, the current output unit 14 further includes: at least two second current output ports, and the ignition position selection knob is also used to switch the second current output port for current output; wherein the output current of the second current output port is greater than the output current of the first current output port. The radiation detection device further includes: a speed sensing module 7 and a speed testing module 8, the speed sensing module 7 being connected to the speed testing module 8, the speed sensing module 7 being used to receive radiation signals and change the connection state with the speed testing module 8. The speed testing module 8 being used to generate a first electrical signal and a second electrical signal according to the connection state. The signal control module 1 is connected between the speed testing module 8 and the industrial control module 3, and is used to input the first electrical signal and the second electrical signal into the industrial control module 3. The industrial control module 3 is used to calculate the transmission speed of the radiation signal based on the first electrical signal and the second electrical signal.

[0081] The radiation detection device can also detect the transmission speed of the radiation signal emitted by the object under test 4. When speed detection is required, the signal control module 1 controls the second current output port to output current, and the current output by the second current output port is greater than the output current of the first current output port. Therefore, this current allows the object under test 4 to react more fully and generate more radiation signal. After the radiation signal is received by the speed sensing module 7, the speed sensing module 7 can disconnect itself from the speed testing module 8. The speed testing module 8 can generate a first electrical signal and a second electrical signal according to the disconnection time. This allows the industrial control module 3 to calculate the transmission speed of the radiation signal based on the first and second electrical signals. For example, the speed testing module 8 may include a digital signal processor (DSP).

[0082] Figure 5 This is a structural schematic diagram of a speed sensing module provided in an embodiment of the present utility model. (Combined with...) Figure 4 and Figure 5Based on the above embodiments, optionally, the speed sensing module 7 includes: a first support 71, a second support 72, a first carbon rod 73, and a second carbon rod 74. The first support 71 and the second support 72 are arranged in parallel; the first support 71 includes a first through hole 711 and a second through hole 712, spaced apart by a first preset distance. The second support 72 includes a third through hole 721 and a fourth through hole 722, the third through hole 721 coinciding with the orthographic projection of the first support 71 and the fourth through hole 722 coinciding with the orthographic projection of the first support 71 and the second through hole 712. The first carbon rod 73 is disposed between the first through hole 711 and the third through hole 721, and the second carbon rod 74 is disposed between the second through hole 712 and the fourth through hole 722; both ends of the first carbon rod 73 and the second carbon rod 74 are connected to the speed testing module 8. The first carbon rod 73 is used to disconnect when receiving a radiation signal emitted by the object under test 4; the second carbon rod 74 is used to disconnect when receiving a radiation signal emitted by the object under test 4.

[0083] In this arrangement, the long sides of the first carbon rod 73 and the second carbon rod 74 are placed facing the object 4 to be tested, and the distance between the first carbon rod 73 and the object 4 to be tested is less than the distance between the second carbon rod 74 and the object 4 to be tested. The placement height of the object 4 to be tested can be the same as the height of the first carbon rod 73 and the second carbon rod 74.

[0084] When the second current output port outputs current, the object under test 4 emits a radiation signal. When the radiation signal passes through the first carbon rod 73, the first carbon rod 73 will break due to radiation, thereby severing the electrical connection between the first carbon rod 73 and the speed test module 8. At this time, the speed test module 8 generates a first electrical signal. When the radiation signal passes through the second carbon rod 74, the second carbon rod 74 will break due to radiation, thereby severing the electrical connection between the second carbon rod 74 and the speed test module 8. At this time, the speed test module 8 generates a second electrical signal.

[0085] Since the distance between the first carbon rod 73 and the second carbon rod 74 is fixed, and the transmission speed of the radiation signal can be calculated by the generation time of the first electrical signal and the second electrical signal. For example, the industrial control module 3 may include a divider, which can calculate the transmission speed of the radiation signal by the difference between the distance between the first carbon rod 73 and the second carbon rod 74 and the generation time of the first electrical signal and the second electrical signal.

[0086] For example, the first bracket 71 and the second bracket 72 may also include multiple through holes, which can be adapted to the actual testing requirements.

[0087] This embodiment of the invention, by setting up a speed sensing module and a speed testing module, allows the carbon rod in the speed sensing module to sense radiation signals and change the connection state with the speed testing module when a radiation signal is received, thereby realizing the calculation of the radiation signal transmission speed. This invention has a simple design structure and good speed detection performance.

[0088] Based on the above embodiments, optionally, the signal control module further includes a key switch, which is connected between the power input terminal of the signal control module and the multiplex analog unit.

[0089] To ensure the safety of radiation characteristic testing, the key switch in the signal control module must be in the off state when radiation characteristic testing is not being performed. For example, the key switch can be turned on or off by rotating the key. When radiation characteristic testing is not being performed, the key switch is in the off state and the key is removed. At this time, the signal control module cannot connect to the power input terminal, effectively preventing the tested object 4 from emitting radiation signals due to accidental activation of the signal control module, thereby affecting the safety and health of relevant personnel.

(Reference) Figure 6 Optionally, the radiation detection device further includes a power supply module 9 and an exhaust fan 10. The power supply module 9 is connected to the signal control module 1, the speed test module 8, the detection module 2, and the exhaust fan 10, and is used to supply power to the signal control module 1, the speed test module 8, the detection module 2, and the exhaust fan 10. The exhaust fan 10 is used to dissipate heat from the radiation detection device.

[0091] When the radiation detection device is started, the power supply module 9 can be used to connect the signal control module 1, the speed test module 8, the detection module 2, and the exhaust fan 10 respectively. For example, the power supply module 9 may include a transformer, which can be used to convert the 220V voltage to a voltage level such as 24V or 28V to adapt to the reliable power consumption of each module in the radiation detection device.
