It should be noted that the embodiments provided by the embodiments of the present application can be combined with each other without conflict.
[0027] Before elaborating on the technical solutions provided by the embodiments of the present application, for the convenience of understanding the embodiments of the present application, the present application first specifically describes the problems existing in the related technologies:
[0028] With the rapid development and application of nuclear power and nuclear technology, the demand for nuclear radiation (X-ray and γ-ray) dose monitoring has increased significantly. Especially in some special fields, such as the nuclear medicine department of hospitals, a large number of medical staff are exposed to radioactive nuclear drugs every day. In the literature "Discussion on Occupational Exposure Monitoring and Radiation Protection of Medical Staff in the Nuclear Medicine Department" in the 16th volume, No. 1 of the "Nursing Practice and Research" journal in 2019, the long-term radiation dose monitoring of medical staff in a hospital's nuclear medicine department was described. In addition to medical staff, there are also patients (mobile radiation sources) injected with radioactive nuclear drugs. These patients generally need to be hospitalized and isolated for a period of time, and the radiation dose in the patients' bodies is monitored until the internal radiation level reaches the specified requirements before they can be discharged. To achieve these monitors, professional radiation monitoring instruments are required to assist in data collection. And to not affect the work, the instruments are required to be as small as possible and have a long battery life, which is convenient for medical staff or other relevant industry workers to wear.
[0029] At present, the vast majority of nuclear radiation dose monitoring instruments on the market can be roughly divided into 3 generations due to the use of different types of detectors: the first-generation gas detectors, such as GM tube detectors; the second-generation scintillator detectors, such as cesium iodide (CsI) detectors; the third-generation semiconductor detectors, such as cadmium zinc telluride (CdZnTe) detectors. The disadvantage of a radiation monitor using the first-generation Geiger counter as a sensor is low sensitivity and a high measurement energy upper limit. The Geiger counter requires several hundred volts of high voltage to work, the instrument has a large volume, high power consumption, and most Geiger counters are extremely easy to break. Using the second-generation scintillator detector requires a photoelectric conversion device. In a certain patent, a personal dosimeter based on a SiPM and a CsI detector was disclosed, where CsI is a scintillator detector and SiPM is a photoelectric conversion device. Its main function is to convert the optical signal of CsI into an electrical signal to be recognized, amplified, and processed by the backend circuit. And the detector has a large size, and the sensitivity is very different from that of cadmium zinc telluride (CdZnTe) under the same detector size.
[0030] To solve the above technical problems, this application proposes a radiation monitoring system, a host, and a device. A radiation monitor designed with a third-generation semiconductor radiation sensor based on cadmium zinc telluride (CdZnTe) solves the problems of high detection sensitivity and low power consumption while reducing the volume of the instrument. And the cadmium zinc telluride (CdZnTe) semiconductor radiation sensor directly outputs an electrical signal. Compared with the second-generation scintillator sensor, the photoelectric conversion unit is omitted.
[0031] First, the following will introduce a radiation monitoring system in this application.
[0032] Figure 1 It is a schematic structural diagram of a radiation monitoring system provided by an embodiment of this application, as Figure 1As shown, the radiation monitoring system 100 may include: a crystal detection module 110, a signal conversion module 120, a comparison module 130, and a collection and processing module 140.
[0033] In some embodiments, the crystal detection module 110 may include a cadmium zinc telluride crystal detector. Since cadmium zinc telluride crystals can be made smaller when performing radiation monitoring compared to other crystals, the selection of cadmium zinc telluride crystal detectors makes the radiation monitoring system designed in this application smaller in volume. And since the cadmium zinc telluride crystal detector outputs a direct electrical signal when receiving a radiation signal, compared to other detection systems, the optoelectronic conversion unit device is omitted, which also makes the radiation monitoring system smaller in volume.
[0034] The crystal detection module 110 is used to generate corresponding charge pulse signals when receiving radiation signals.
[0035] The radiation signals include X-rays, γ-rays, and other radiation signals.
[0036] The signal conversion module 120 is electrically connected to the crystal detection module 110, and the signal conversion module 120 is used to convert the charge pulse signal into a quasi-Gaussian signal.
[0037] The comparison module 130 is electrically connected to the signal conversion module 120, and the comparison module 130 is used to classify and digitize the quasi-Gaussian signal and output the corresponding digital pulse signal.
[0038] In some embodiments, the comparison module 130 may include a channel comparator, for example, a low-power four-channel comparator. The low-power four-channel comparator can divide the quasi-Gaussian signal into four different signals according to the signal amplitude size, and then output them to the collection and processing module for calculation.
[0039] The collection and processing module 140 is electrically connected to the comparison module 130, and the collection and processing module 140 is used to receive the digital pulse signal and convert the digital pulse signal into the corresponding radiation dose value. The collection and processing module 140 may include an ultra-low-power microcontroller unit (MCU).
[0040] When X-rays and γ-rays act on the crystal detection module, the crystal detection module generates charge pulse signals. After the signal conversion module converts the signals into quasi-Gaussian signals that are easier to classify, the comparison module classifies and digitizes the quasi-Gaussian signals to obtain the corresponding digital pulse signals. The collection and processing module calculates the corresponding radiation dose value based on the digital pulse signals, thereby realizing the process of radiation monitoring. Relevant industry practitioners can evaluate the magnitude of the radiation dose they receive based on this dose value. Since the optoelectronic conversion unit is omitted compared to other detectors, the radiation monitoring system in this application is smaller in volume and convenient to wear.
[0041] Figure 2 It is another schematic structural diagram of the radiation monitoring system provided by the embodiments of the present application. As Figure 2 shown, the signal conversion module 120 may include a charge integration and amplification unit 121, an operational amplification unit 122, and a signal shaping unit 123.
[0042] The charge integration and amplification unit 121 is electrically connected to the crystal detection module 110. The charge integration and amplification unit 121 is used to convert the charge pulse signal into a voltage pulse signal; the operational amplification unit 122 is electrically connected to the charge integration and amplification unit 121. The operational amplification unit 122 is used to receive the voltage pulse signal and amplify the voltage pulse signal to obtain an amplified voltage pulse signal; the signal shaping unit 123 is electrically connected to the operational amplification unit 122. The signal shaping unit 123 is used to shape the amplified voltage pulse signal to obtain a quasi-Gaussian signal.
[0043] Figure 3 It is yet another schematic structural diagram of the radiation monitoring system provided by the embodiments of the present application. As Figure 3 shown, the radiation monitoring system 100 may further include: a Bluetooth wireless communication unit 150, an indicator light 160, a vibration motor 170, and a power acquisition unit.
[0044] The Bluetooth wireless communication unit 150 is electrically connected to the acquisition and processing module 140. The Bluetooth wireless communication unit 150 is used for Bluetooth transparent transmission with a mobile client. It should be noted that the mobile client is an external mobile phone. That is, the Bluetooth wireless communication unit 150 is used for communication with an external mobile phone.
[0045] In some embodiments, the mobile client can wake up the radiation monitoring system through Bluetooth, so as to avoid the radiation monitoring system being always started and reduce the power consumption of the radiation monitoring system.
[0046] The radiation monitoring system of the present application can adopt a brand-new low-power processing method, that is, the MCU in the radiation monitoring system of the present application has a sleep or standby state, and other modules and units do not. To reduce the power consumption of the radiation monitoring system, the MCU will be woken up only when at least one of the following three conditions is met.
[0047] (1) When the crystal detection module detects that the radiation dose is greater than a certain value, the MCU is woken up;
[0048] (2) When the Bluetooth wireless communication module detects an external request for Bluetooth communication, the MCU is woken up;
[0049] (3) When neither of the above two conditions is met, the MCU enters the sleep state. During the sleep period of the MCU, the MCU wakes up actively every once in a while to read the value of the external counter, accumulates and saves it, and then enters the sleep state.
[0050] Figure 4 It is a schematic diagram of the working logic of the radiation monitoring system provided by an embodiment of the present application. As Figure 4 shown, as long as the crystal detection module detects that the radiation count is greater than the background level, or the radiation monitoring system detects an external request for Bluetooth communication, the MCU is immediately awakened to process the current situation. After the current situation is processed, when the system detects that the radiation dose is always at the background level within 5 minutes and there is no external request for Bluetooth connection communication, the MCU enters the sleep state. The key device responsible for detecting and awakening the MCU is an external counter.
[0051] Due to the different sizes of cadmium zinc telluride crystal detectors, the number of responses to cosmic background is different. The cosmic background response data of the cadmium zinc telluride crystal detector used in this system is 1-2 counts per second, and this data can be used as a parameter to evaluate whether the radiation count exceeds the background level. The cumulative dose is a very useful indicator in radiation protection work, which can summarize and evaluate the exposure status of an individual based on the risk. During the normal operation of the MCU, the cumulative dose can be normally counted, but during the sleep period, the calculation of the cumulative dose is that the MCU actively wakes up every once in a while to read the value of the counter, accumulates and saves it, and then continues to enter the sleep state.
[0052] The indicator light 160 is electrically connected to the acquisition and processing module 140; in some embodiments, the indicator light includes an alarm indicator light and / or a working mode display indicator light, and the colors of the alarm indicator light and the working mode display indicator light are different.
[0053] The vibration motor 170 is electrically connected to the acquisition and processing module 140, and the vibration motor 170 is used to vibrate when the radiation dose value exceeds the background level.
[0054] The indicator light 160 can be used in cooperation with the vibration motor 170. Exemplarily, when the radiation monitoring system is in the working mode, the working mode display indicator light (green) in the indicator light 160 starts to work. When in the scanning mode of the working mode, the green light flashes at intervals of 20S; when in the monitoring mode of the working mode, the green light flashes at intervals of 1S. When the surrounding radiation exceeds the standard, the alarm indicator light (red) starts to work. When the radiation exceeds the standard and alarms, the red light flashes quickly at intervals of 0.5S and the host vibrates; or when the battery power is insufficient, the red light is always on.
[0055] The battery power acquisition unit 180, and the battery power acquisition unit 180 is electrically connected to the acquisition and processing module 140. The battery power acquisition unit is used to display the current power of the radiation monitoring host.
[0056] Continue to participate Figure 3, in some embodiments, the radiation monitoring system further includes: a power management subsystem 190, which is electrically connected to the crystal detection module 110, the signal conversion module 120, the comparison module 130, and the acquisition and processing module 140, and is used to supply power to the crystal detection module 110, the signal conversion module 120, the comparison module 130, and the acquisition and processing module 140.
[0057] Figure 3 Taking the acquisition and processing module 140 as an ultra-low power consumption MCU and the comparison module 130 as a low-power four-channel comparator as an example.
[0058] The power management subsystem 190 may include: a lithium battery 191, a first power management module 192, a voltage unit 193, a second power management module 194, and a wireless charging management unit 195.
[0059] The lithium battery 191; the first end of the first power management module 192 is electrically connected to the lithium battery 191, and the second end of the first power management module 192 is electrically connected to the signal conversion module 120.
[0060] The first end of the voltage unit 193 is electrically connected to the third end of the first power management module 192, the second end of the voltage unit 193 is electrically connected to the crystal detection module, and the voltage unit 193 is used to amplify the voltage of the first power management module 192 and provide the amplified voltage to the crystal detection module 110.
[0061] In some embodiments, the voltage unit may be a high-voltage module unit, and some crystal detection modules require high-voltage startup.
[0062] The first end of the second power management module 194 is electrically connected to the comparison module 130, the second end of the second power management module 194 is electrically connected to the acquisition and processing module 140, the third end of the second power management module 194 is electrically connected to the battery power acquisition unit 180, the vibration motor 170, the indicator light 160, and the Bluetooth wireless communication unit 150; the wireless charging management unit 195, and the wireless charging management unit 195 is electrically connected to the lithium battery 191.
[0063] Since different modules or units require different voltages to start, the present application provides a first power management module and a second power management module to meet different voltage requirements.
[0064] The above is the structural design of the radiation monitoring system in the present application. The radiation monitoring system is located in the radiation monitoring host, and the radiation monitoring host is a part of the radiation monitoring device.
[0065] Figure 5 This is a schematic structural diagram of the radiation monitoring device in the present application, as Figure 5As shown in the figure, the radiation monitoring device includes: the above-mentioned radiation monitoring host, a wireless charging base, and a silicone hanging strap.
[0066] The wireless charging base is electrically connected to the wireless charging management unit of the radiation monitoring host. The wireless charging base is provided with a wireless charging indicator light and a charging port.
[0067] The silicone hanging strap includes a protection part and a hanging loop. The protection part is arranged around the radiation monitoring host, and the hanging loop is connected to the protection part. In some embodiments, the radiation monitoring device may include two matching silicone hanging straps. Figure 5 This is one of them. The silicone hanging strap can also be set in the style of a watch loop for the convenience of the user to wear. The styles of the silicone hanging strap are not listed one by one here.
[0068] Regarding the indicator light in the radiation detection device in this application, exemplarily, the embodiments of this application can use three-color (red, blue, green) lights and vibration to prompt information.
[0069] (1) When the host is in use:
[0070] ① Scanning mode: The green light flashes at intervals of 20S.
[0071] ② Monitoring mode: The green light flashes at intervals of 1S.
[0072] ③ Radiation over-limit alarm: The red light flashes quickly at intervals of 0.5S, and the host vibrates.
[0073] ④ Insufficient power: The red light is always on.
[0074] (2) Charging base status:
[0075] ① Charging: The blue light on the charging base is always on.
[0076] ② Charging anomaly: The blue light flashes quickly at intervals of 0.5S or does not light up.
[0077] (3) When the host is charging:
[0078] ① Charging: The blue light is always on.
[0079] ② Fully charged: The blue light goes out.
[0080] As Figure 4 shown, the indicator light of the radiation monitoring host can be located at the center of the host screen. The radiation monitoring device in this application solves the problems that while reducing the volume of the instrument, it also ensures high detector sensitivity and low power consumption, etc.
[0081] The radiation monitoring device in this application is relatively small in size. The overall dimensions of the device can reach only 55mm×38mm×12mm. Low power consumption means that the overall power consumption of the device is only 1.65mW, and the theoretically sustainable working time can reach 1000 hours. High sensitivity means that when the detector size is only 5mm×5mm×1mm, the sensitivity is 1.9 cps / uSv / h. This well solves the problem that it is inconvenient to carry and has a short battery life in special occasions. For example, in the DR operating room of a hospital, doctors need to detect the received radiation dose while performing surgery. If the instrument size is too large, it will directly affect wearing.
