Description

Technical Field

[0001] The utility model relates to the technical field of ray detection, and more specifically, to a ray detection device. Background Art

[0002] In the prior art, there is no security inspection equipment specifically used to detect the authenticity of electronic products such as mobile phones, tablets and smart wearable devices. Traditional X-ray security inspection equipment mainly focuses on relatively large dangerous items, such as controlled knives, firearms and ammunition, and flammable and explosive items. Traditional X-ray security inspection equipment requires a transmission device, and the equipment is large in size and occupies a large area. Another type of portable X-ray inspection equipment is mainly used for explosion-proof inspection. Since portable X-ray inspection equipment has no protective device, a relatively large protective distance is required during inspection, and the use scenario is limited.

[0003] In summary, the two types of X-ray security inspection equipment are not suitable for checking the authenticity of electronic products such as mobile phones and tablets. Therefore, in the field of electronic product security inspection, there is no good means to check the additional modification of electronic products, the addition of small chips in electronic products, the change of circuits, and other dangerous behaviors such as counterfeiting of mobile phones, and / or the storage of small amounts of explosives in electronic products. Electronic products have become a hidden danger threatening people's health and property safety. Moreover, the above two types of X-ray security inspection equipment only judge the authenticity and dangerousness of the inspected products through X-ray images, and the detection accuracy is low; in addition, the above two types of X-ray security inspection equipment need to generate X-ray images that can be clearly judged, which requires higher X-ray energy and dose, and higher X-ray energy and dose will waste resources.

[0031] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concept of the present invention. In addition, the various embodiments provided below by the present invention and the technical features in the embodiments can be combined with each other in any manner.

[0032] The terms used herein are only for describing specific embodiments and are not intended to limit the present invention. In addition, the terms "including", "comprising", etc. used herein indicate the presence of the features, steps, operations and / or components, but do not exclude the presence or addition of one or more other features, steps, operations or components.

[0033] In the prior art, there is no security inspection equipment specifically used to detect the authenticity of electronic products such as mobile phones, tablets and smart wearable devices. Traditional X-ray security inspection equipment mainly focuses on relatively large dangerous items, such as controlled knives, firearms and ammunition, and flammable and explosive items. Traditional X-ray security inspection equipment requires a transmission device, and the equipment is large in size and occupies a large area. Another type of portable X-ray inspection equipment is mainly used for explosion-proof inspection. Since portable X-ray inspection equipment has no protective device, a relatively large protective distance is required during inspection, and the use scenario is limited.

[0034] In summary, the two types of X-ray security inspection equipment are not suitable for checking the authenticity of electronic products such as mobile phones and tablets. Therefore, in the field of electronic product security inspection, there is no good means to check the additional modification of electronic products, the addition of small chips in electronic products, the change of circuits, and other dangerous behaviors such as counterfeiting of mobile phones, and / or the storage of small amounts of explosives in electronic products. Electronic products have become a hidden danger threatening people's health and property safety. Moreover, the above two types of X-ray security inspection equipment only judge the authenticity and dangerousness of the inspected products through X-ray images, and the detection accuracy is low.

[0035] Reference below Figure 1 A radiation detection device 100 according to an embodiment of the present invention is described.

[0036] like Figure 1 As shown, the radiation detection device 100 according to the embodiment of the utility model includes a protective shell 1, a radiation source 2, a detector 3, a weighing device 4 and a control device 5.

[0037] Specifically, combined Figure 1The protective shell 1 has a accommodating cavity 11, and the accommodating cavity 11 has an open mouth. A switch door 12 is provided at the open mouth to open and close the open mouth; a radiation source 2 is arranged in the accommodating cavity 11; a detector 3 is arranged in the accommodating cavity 11, and the product to be inspected is suitable for being placed between the radiation source 2 and the detector 3 to be scanned by the radiation source 2; a weighing device 4 is arranged in the accommodating cavity 11, and is used to weigh the product to be inspected; a control device 5 is communicatively connected with the radiation source 2, the detector 3 and the weighing device 4, and is used to control the beam emission of the radiation source 2, receive the radiation signal of the detector 3 and receive the weight information of the weighing device 4, process the radiation signal and the weight information, and obtain the detection result.

[0038] It is understandable that arranging the radiation source 2, the detector 3 and the weighing device 4 in the protective shell 1 can protect the security inspectors when the radiation source 2 emits a beam to inspect the product to be inspected, and reduce the damage to the health of the security inspectors caused by the radiation. The accommodating cavity 11 can facilitate the arrangement of the radiation source 2, the detector 3 and the weighing device 4 in the protective shell 1. The open mouth can facilitate the security inspectors to place the product to be inspected between the radiation source 2 and the detector 3, and also facilitate the security inspectors to take the product to be inspected out of the accommodating cavity 11. The switch door 12 can be used to open and close the open mouth to facilitate the placement of the product to be inspected. For example, the switch door 12 can be a radiation protection door. During radiation detection, the switch door 12 closes the open mouth to prevent radiation leakage.

[0039] According to the radiation detection device 100 of the embodiment of the utility model, by arranging the radiation source 2, the detector 3 and the weighing device 4 in the protective shell 1, the health of the security personnel can be protected when the radiation source 2 and the detector 3 are working. By taking and placing the products to be inspected through the open mouth, the inspection of the products to be inspected can be realized without a conveyor belt, which can reduce the volume of the radiation detection device 100, thereby reducing the footprint of the radiation detection device 100. In addition, compared with the portable X-ray inspection equipment in the prior art, the radiation detection device 100 of the utility model has a protective shell 1, so a relatively large protection distance is not required during the inspection, and the use scenario is flexible. In addition, the utility model can obtain the weight information of the product to be inspected through the weighing device 4, and the control device 5 can obtain the detection result through the comprehensive analysis of the radiation signal and the weight information. Compared with the result obtained by only analyzing the radiation signal, the conclusion of the detection result is more accurate. Compared with the traditional radiation detection equipment, the utility model only needs to analyze the radiation signal, and does not need to obtain a clear image, so the required radiation energy is lower and the dose is smaller, while saving resources, it is more conducive to radiation protection and reducing the volume of the equipment.

[0040] In some examples, the security personnel may include all persons near the radiation detection device 100 during the security inspection, including but not limited to operators of the radiation detection device 100 and owners of electronic products, etc. The communication connection may include a signal connection and an electrical connection, and the electrical connection may include a wire connection.

[0041] In some instances, such as Figure 1 As shown, the control device 5 can be disposed in the accommodating cavity 11 . In some examples, the control device 5 is outside the protective shell 1 .

[0042] According to some embodiments of the present invention, Figure 1 As shown, the weighing device 4 may include a weighing actuator 41 and a weighing processor 42. The weighing actuator 41 is arranged in the accommodating cavity 11, and the product to be inspected is suitable for being placed in the weighing actuator 41, and the weighing actuator 41 generates a weight signal; the weighing processor 42 is in communication connection with the weighing actuator 41 and the control device 5, receives the weight signal, processes the weight signal, obtains the weight information, and sends the weight information to the control device 5. Therefore, the weighing actuator 41 and the weighing processor 42 can facilitate the weighing device 4 to weigh the product to be inspected, obtain the weight information, and transmit the weight information to the control device 5.

[0043] According to some embodiments of the present invention, Figure 1 As shown, the weighing actuator 41 is arranged between the radiation source 2 and the detector 3, and the product to be inspected is suitable for being placed on the weighing actuator 41, and is scanned by the radiation source 2, and the weighing actuator 41 generates a weight signal. Therefore, the weighing actuator 41 can support the product to be inspected for radiation scanning on the one hand, and can weigh the product to be inspected on the other hand. Since the weighing actuator 41 plays the role of a support, there is no need to set up a separate support, so that the overall volume of the radiation detection equipment 100 is small, the floor space is small, and the manufacturing cost is low.

[0044] In some embodiments of the present invention, Figure 1 As shown, in the up and down direction, the radiation source 2 is arranged above the weighing actuator 41 , and the detector 3 is arranged below the weighing actuator 41 .

[0045] Alternatively, in the up-down direction, the radiation source 2 is disposed below the weighing actuator 41 , and the detector 3 is disposed above the weighing actuator 41 .

[0046] Both of the above-mentioned methods can facilitate the arrangement of the radiation source 2 , the weighing actuator 41 and the detector 3 , so that the weighing actuator 41 can be conveniently arranged between the radiation source 2 and the detector 3 .

[0047] In some embodiments of the present invention, in the left-right direction, the ray source 2 is disposed on the left side of the weighing actuator 41 , and the detector 3 is disposed on the right side of the weighing actuator 41 .

[0048] Alternatively, in the left-right direction, the radiation source 2 is disposed on the right side of the weighing actuator 41 , and the detector 3 is disposed on the left side of the weighing actuator 41 .

[0049] Both of the above-mentioned methods can facilitate the arrangement of the radiation source 2 , the weighing actuator 41 and the detector 3 , so that the weighing actuator 41 can be conveniently arranged between the radiation source 2 and the detector 3 .

[0050] In some embodiments of the utility model, a first fixing portion is provided on the weighing actuator 41, and the first fixing portion fixes the product to be inspected so that the scanning surface of the product to be inspected is parallel to the area between the ray source 2 and the detector 3. It is understandable that since the shape of the product to be inspected may not be convenient for placement, that is, it may fall or tilt after placement, so that the scanning surface of the product to be inspected cannot be located between the ray source 2 and the detector 3, the first fixing portion can facilitate the fixing of the product to be inspected so that the scanning surface of the product to be inspected is parallel to the area between the ray source 2 and the detector 3, so as to facilitate the completion of the inspection.

[0051] In some embodiments of the present invention, in the front-to-back direction, the radiation source 2 is disposed in front of the weighing actuator 41 , and the detector 3 is disposed behind the weighing actuator 41 .

[0052] Alternatively, in the front-to-back direction, the radiation source 2 is disposed behind the weighing actuator 41 , and the detector 3 is disposed in front of the weighing actuator 41 .

[0053] Both of the above-mentioned methods can facilitate the arrangement of the radiation source 2 , the weighing actuator 41 and the detector 3 , so that the weighing actuator 41 can be conveniently arranged between the radiation source 2 and the detector 3 .

[0054] In some embodiments of the utility model, a second fixing part is provided on the weighing actuator 41, and the second fixing part fixes the product to be inspected so that the scanning surface of the product to be inspected is parallel to the area between the ray source 2 and the detector 3. It can be understood that since the shape of the product to be inspected may not be convenient for placement, that is, it will fall or tilt after placement, so that the scanning surface of the product to be inspected cannot be located between the ray source 2 and the detector 3, the second fixing part can facilitate the fixing of the product to be inspected so that the scanning surface of the product to be inspected is parallel to the area between the ray source 2 and the detector 3, so as to facilitate the completion of the inspection.

[0055] In some embodiments of the utility model, in the up-down direction, the ray source 2 is arranged above the product to be inspected, the product to be inspected is arranged on the detector 3, the detector 3 and the product to be inspected are arranged as a whole on the weighing actuator 41, and the weighing actuator 41 generates a weight signal. In some examples, a support may be provided on the detector 3, the product to be inspected is arranged on the support, and the weighing actuator 41 weighs the detector 3, the product to be inspected and the support as a whole, and then transmits the overall weight to the weighing processor 42, the weighing processor 42 may pre-store the weight of the detector 3 and the support, the weighing processor 42 may calculate the weight information of the product to be inspected, and then transmit the weight information to the control device 5. This method can also facilitate the arrangement of the ray source 2, the weighing actuator 41 and the detector 3, so that the inspection of the product to be inspected can be realized.

[0056] In some embodiments of the utility model, the weighing actuator 41 may include a tray and a weight sensor. The product to be inspected is suitable for being placed on the tray; the weight sensor is connected to the tray, and generates a weight signal according to the load of the tray; the weight sensor is connected to the weighing processor 42 for communication, and sends the weight signal to the weighing processor 42. Thus, it is convenient to realize that the weighing actuator 41 generates a weight signal, so that it is convenient for the weighing device 4 to weigh the product to be inspected and obtain weight information.

[0057] In some examples, the weighing processor may include a signal amplifier, a digital-to-analog converter, and a data processor. The signal amplifier receives the weight signal, amplifies it, and then transmits it to the digital-to-analog converter. The digital-to-analog converter converts the analog signal of the weight signal into a digital signal and transmits it to the data processor. The data processor calculates the weight information corresponding to the weight signal based on the digital signal. The unit of the weight information can be grams, kilograms, or catties, etc.

[0058] According to some embodiments of the present invention, the opening can be located on the side or top of the protective shell. It is understandable that the opening can be opened at any position that is convenient for taking and placing the product to be inspected, thereby improving the inspection efficiency.

[0059] According to some embodiments of the present invention, the switch door may include a flat door, a side door or a double door. The switch door can be set in a manner that is selected according to the structure and placement space of the radiation detection device to facilitate opening and closing.

[0060] According to some embodiments of the utility model, the radiation detection equipment may further include a first safety interlock, the first safety interlock includes a first locking part and a second locking part, the first locking part is arranged at the open mouth, the second locking part is arranged at the switch door, the first safety interlock is communicatively connected with the control device, and when the first locking part and the second locking part cooperate, the control device can control the radiation source to emit a beam. It is understandable that when the switch door is in an open state, the first locking part and the second locking part are not cooperated, and the control device cannot control the radiation source to emit a beam. When the switch door is in a closed state, and the first locking part and the second locking part cooperate, the control device can control the radiation source to emit a beam. In this way, it is possible to avoid the problem of radiation leakage caused by performing radiation detection without closing the open mouth of the switch door. The switch door is a door made of radiation-proof material.

[0061] According to some embodiments of the utility model, the switch door is formed into a drawer structure, which can be pushed and pulled at the open mouth to close and open the open mouth, and the drawer includes a loading part and a blocking part, the loading part is connected to the blocking part, the loading part is located between the radiation source and the detector, and the product to be inspected is suitable for being placed in the loading part. When the switch door is pushed into the open mouth, the blocking part blocks the open mouth. Among them, the blocking part is made of radiation-proof material. The switch door of the drawer structure can make the radiation detection equipment smaller in size and occupy a smaller area.

[0062] According to some embodiments of the utility model, the radiation detection device may further include a second safety interlock, the second safety interlock includes a third locking part and a fourth locking part, the third locking part is arranged at the open mouth, the fourth locking part is arranged in the drawer, the second safety interlock is communicatively connected with the control device, and when the third locking part and the fourth locking part cooperate, the control device can control the radiation source to emit a beam. It is understandable that when the drawer is in a pulled-out state, the third locking part and the fourth locking part are not cooperated, and the control device cannot control the radiation source to emit a beam. When the drawer is in a pushed-in state, and the third locking part and the fourth locking part cooperate, the control device can control the radiation source to emit a beam. In this way, it is possible to avoid the problem of radiation leakage caused by performing radiation detection before the drawer is pushed into the open mouth.

[0063] According to some embodiments of the present invention, when the radiation source and the detector are arranged in the vertical direction, the weighing actuator is arranged between the radiation source and the detector, and the weighing processor is arranged in the accommodating cavity and located on the side of the weighing actuator. In this way, the influence of the radiation on the weighing processor can be avoided, so that the processing result of the weighing processor is more accurate.

[0064] When the radiation source and the detector are arranged in the front-to-back direction or the left-to-right direction, the weighing actuator is arranged between the radiation source and the detector, and the weighing processor is arranged in the accommodating cavity and below the weighing actuator. Thus, without affecting the accuracy of the weighing processor, the weighing processor and the weighing actuator are more easily associated, and the weighing processor is conveniently arranged.

[0065] According to some embodiments of the present invention, the radiation detection device may further include a power supply device to supply power to components of the radiation detection device that require electricity.

[0066] According to some embodiments of the utility model, the radiation detection equipment may further include a control panel, which is communicatively connected to the control device, and the radiation source may be operated to emit and stop the beam on the control panel. The control panel may display the final conclusion of whether the product to be inspected has been modified.
