[0002] In various examinations, in order to ensure the fairness of the examinations and prevent candidates from cheating by using electronic devices or other metal objects, examination rooms are usually equipped with metal detectors for inspection. An existing handheld metal detector is named because it is used by holding it in the hand. It can detect weapons, explosives or small metal objects carried by people, and can be used in different occasions such as anti-cheating in examination rooms. However, the existing handheld metal detectors have a relatively single function and can usually only be used to detect metal, but not mobile phones. Therefore, in the examination room, in addition to using handheld metal detectors to detect whether there is metal on the candidates, it is also necessary to set up a mobile phone detection door to detect the candidates. This will increase the layout cost of the examination room and reduce the efficiency of security checks in the examination room.

Similarly, the metal detector can only be used to detect metals, and cannot detect a variety of different items such as mobile phones.

[0027] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0028] In view of the defect that the existing handheld metal detectors can only be used to detect metals but cannot detect a variety of different objects such as mobile phones, the present application provides an intelligent safety detector for use in the field of examinations.

[0029] Example 1

[0030] like Figure 1-Figure 4 As shown, this embodiment provides an intelligent safety detector for use in the field of examinations, the detector comprising a main body 1; a first detection structure 5 and a second detection structure 6 are provided in the main body 1, the second detection structure 6 is located on one side of the first detection structure 5, the first detection structure 5 is used to execute a first detection mode, and the second detection structure 6 is used to execute a second detection mode;

[0031] The main body 1 is provided with a controller 4 and a control button 21, and the control button 21, the first detection structure 5, and the second detection structure 6 are all electrically connected to the controller 4; the control button 21 is used to control the controller 4 so that the controller 4 is electrically connected to the first detection structure 5 or the second detection structure 5.

[0032] It should be noted that the controller 4 of the present application automatically executes the first detection mode or the second detection mode according to the control button 21, which is realized by the circuit inside the controller 4, and this circuit is a prior art, so the present application does not describe the specific circuit structure. However, those skilled in the art can know that when the controller 4 executes the first detection mode, the controller 4 is electrically connected to the first detection structure 5, and the first detection mode is realized through the first detection structure 5; when the controller executes the second detection mode, the controller 4 is electrically connected to the second detection structure 6, and the second detection mode is realized through the second detection structure 6.

[0033] Specifically, in one embodiment, the first detection mode is used to detect metal. In the detector of the present application, the first detection structure 5 can use electromagnetic induction technology to accurately detect whether the examinee carries metal objects, such as watches, keys, metal accessories, etc. This detection mode is crucial to maintaining the fairness and security of the examination. The second detection structure 6 is responsible for executing the second detection mode, namely mobile phone detection. This structure uses radio frequency identification technology to effectively detect whether the examinee carries a mobile phone or other communication device that is turned on, turned off, or even in flight mode. This function is particularly critical for preventing cheating in examinations.

[0034] The above-mentioned intelligent security detector applied to the examination field, in actual application, the first detection mode of the detector is used for metal detection, and the second detection mode is used for mobile phone detection, and the processor receives and processes the signal from the detection structure to determine whether there is metal or mobile phone on the examinee. The control button 21 enables the invigilator to easily switch between the first detection mode and the second detection mode to adapt to different security inspection requirements, and meets the needs of metal detection and mobile phone detection on one detector, which can effectively prevent the examinee from bringing prohibited items into the examination room, thereby maintaining the fairness and security of the examination. During use, the invigilator only needs to press the corresponding control button 21, and the intelligent security detector can quickly switch to the required detection mode. This flexibility and convenience greatly improves the efficiency and accuracy of examination security inspection.

[0035] Furthermore, a first cavity 161 and a second cavity 162 are provided in the main body 1, and the second cavity 162 is provided on one side of the first cavity 161; the first detection structure 5 is provided in the first cavity 161; the first detection structure 5 includes a first transmitting coil 51 and a first receiving coil 52, and two first receiving coils 52 are provided, and the two first receiving coils 52 are relatively provided on one side of the transmitting coil, and the transmitting coil is electrically connected to the controller 4.

[0036] The main body 1 of the intelligent safety detector is further subdivided into a first cavity 161 and a second cavity 162, which are arranged adjacent to each other and separated by a certain isolation structure to ensure that the detection structures in each cavity can work independently and stably. The first detection structure 5 is composed of a first transmitting coil 51 and two first receiving coils 52. The first transmitting coil 51 is located in the center and is responsible for generating a changing electromagnetic field. The two first receiving coils 52 are arranged on one side of the transmitting coil to receive the induction signal generated by the metal object in the electromagnetic field. This configuration not only improves the sensitivity of detection, but also helps to locate and identify metal objects more accurately. The controller 4 is electrically connected to the first transmitting coil 51 and is responsible for controlling it to generate an electromagnetic field of appropriate frequency and intensity. At the same time, the controller 4 also receives the signal from the first receiving coil 52, determines whether there is a metal object after processing, and intuitively displays the detection results to the invigilator through the display screen 13 or indicator light.

[0037] In a more specific embodiment, the second detection structure 6 is disposed in the second cavity 162, and the second detection structure 6 includes a second receiving coil 62 and a second transmitting coil 61, the second receiving coil 62 and the second transmitting coil 61 are both disposed in the second cavity 162, the second transmitting coil 61 is located on one side of the second receiving coil 62, and the second transmitting coil 61 is electrically connected to the controller 4.

[0038] The present application places detection structures with different functions in separate cavities, thereby achieving a modular design and facilitating maintenance, upgrading and expansion of the equipment.

[0039] In actual applications, the second detection structure 6 is specifically used for detecting electronic devices such as mobile phones. The second detection structure 6 uses electromagnetic waves to detect electronic devices such as mobile phones. When the electromagnetic waves emitted by the second transmitting coil 61 encounter electronic devices such as mobile phones, these devices will generate specific reflection or interference signals. These signals are then captured by the second receiving coil 62 and transmitted to the controller 4 for processing. By analyzing the characteristics of these signals, the controller 4 can accurately determine whether there is an electronic device and notify the invigilator through the display screen 13, sound prompts or other methods.

[0040] It should be noted that, in another embodiment, the first detection structure 5 of the present application mainly uses the electromagnetic induction principle to detect metal, and the second detection structure 6 can use radio spectrum analysis technology to detect mobile phones.

[0041] Furthermore, the main body 1 includes a first shell 11 and a second shell 12 that are clamped together, and a mounting cavity is formed between the first shell 11 and the second shell 12;

[0042] The installation cavity includes a sensing area 16, a control area 17 and a power supply area 18 which are connected in sequence. The first detection structure 5 and the second detection structure 6 are arranged in the sensing area 16, the controller 4 is arranged in the control area 17, and a power supply 3 is arranged in the power supply area 18. The power supply 3 is electrically connected to the controller 4.

[0043] In this embodiment, the structure of the main body 1 is described. The main body 1 includes a first shell 11 and a second shell 12. The two shells are tightly matched to form a complete main body 1 structure, which is not only beautiful in appearance, but also stable in structure, and can effectively protect the internal electronic components from the influence of the external environment.

[0044] An installation cavity is formed between the first shell 11 and the second shell 12, and the installation cavity is divided into a sensing area 16, a control area 17 and a power supply area 18. This partition design makes each functional module relatively independent, does not interfere with each other, and is easy to maintain. The sensing area 16 is an important part of the installation cavity, and a first detection structure 5 and a second detection structure 6 are arranged in the sensing area 16. These two detection structures are responsible for metal detection and electronic device detection, respectively, and together constitute the core sensing function of the intelligent safety detector. By concentrating the detection structure in the sensing area 16, not only the detection efficiency is improved, but also it is helpful to reduce signal interference and ensure the accuracy of the detection results. Preferably, an indicator light can also be set in the sensing area 16 to reflect the detection results. For example, when metal is detected, the indicator light flashes a red signal; when no metal is detected, the indicator light flashes a green signal.

[0045] The control area 17 is used to install the controller 4, which is the "brain" of the intelligent safety detector. The controller 4 is responsible for receiving the signal from the sensing area 16 and performing data processing and analysis. By placing the controller 4 alone in the control area 17, the electromagnetic interference from other areas can be effectively isolated to ensure the stable operation of the controller 4. The controller 4 of the present application can be implemented by an existing single-chip microcomputer or MCU. The power supply area 18 is provided with a power supply 3 to provide stable power support for the entire detector. The power supply 3 is electrically connected to the controller 4 to ensure the normal operation of the controller 4 and other electronic components. At the same time, the independent design of the power supply area 18 is also conducive to the heat dissipation and safety management of the power supply. It should be noted that the power supply 3 of the present application adopts a rechargeable power supply, and the charging area is provided with a connector for charging the power supply 3.

[0046] Furthermore, a LORA communication module 41 is provided in the control area 17, and the LORA communication module 41 is electrically connected to the controller 4. The LORA communication module 41 is a wireless communication module based on the LORA (Long Range) technology, which has the characteristics of long transmission distance, low power consumption, strong anti-interference ability, etc. In this embodiment, the LORA communication module 41 is integrated into the control area 17 and closely cooperates with the controller 4 to realize wireless communication between the intelligent safety detector and the remote monitoring center or other intelligent devices.

[0047] Through the LORA communication module 41, the intelligent safety detector can upload detection results, equipment status and other information to the remote monitoring center in real time, and receive instructions or data updates from the monitoring center. This wireless communication method not only greatly simplifies wiring and maintenance work, but also makes the use of the detector more flexible and convenient.

[0048] In addition, the low power consumption characteristics of the LORA communication module 41 also help to extend the battery life of the smart safety detector, reduce energy consumption during long-term use, and improve the efficiency of equipment use.

[0049] Furthermore, a display screen 13 is also provided in the control area 17, the display screen 13 is exposed on the first housing 11, and the display screen 13 is electrically connected to the controller 4. The display screen 13 is also electrically connected to the power supply 3. The interactive experience between the user and the detector is improved, and the usability and intuitiveness of the device are also enhanced.

[0050] In a specific application, when the detector detects prohibited items such as metal or mobile phones, the display screen 13 will immediately display a corresponding warning message, such as "metal detected" or "mobile phone detected", and may be accompanied by sound or light prompts so that the invigilator can respond quickly. In addition to the basic detection results, the display screen 13 can also display other relevant information, such as power level, device number, user guide, etc., enriching the functionality of the device. In one use method, the display screen 13 can also display the configured examination room and examination center information.

[0051] In a more preferred embodiment, a camera 131 is further provided on the main body 1 , and the camera 131 is electrically connected to the controller 4 .

[0052] The addition of camera 131 enables the intelligent safety detector to not only detect prohibited items such as metal and mobile phones, but also monitor the examination room environment in real time and capture the dynamic situation in the examination room. This visual monitoring function provides invigilators with a more comprehensive examination room management method, which helps to detect and deal with various abnormal situations in a timely manner.

[0053] In actual applications, the camera 131 can also be used to perform facial recognition on the examinee to verify whether the examinee's information is accurate.

[0054] More specifically, the main body 1 is provided with a handle 14, and a hanging rope 15 is provided at one end of the handle 14;

[0055] The main body 1 is provided with a mounting groove 2 , the mounting groove 2 is provided on one side of the handle 14 , and the control button 21 is provided in the mounting groove 2 .

[0056] The detector of the present application is provided with a handle 14, and a lanyard 15 is provided on the handle 14.

At the same time, a lanyard 15 is also provided at one end of the handle 14, and the user can conveniently hang the detector on the wrist for easy carrying and use. The mounting groove 2 is located on one side of the handle 14, which is both beautiful and does not affect the grip.

[0057] Furthermore, an RFID reader 132 is also provided in the main body 1 , and the RFID reader 132 is electrically connected to the controller 4 .

[0058] RFID technology, that is, wireless radio frequency identification technology, uses radio signals to identify specific targets and read and write related data. In this embodiment, the RFID reader 132 is used to implement the question card inventory function. For example, an RFID tag is attached to each question card, and each tag has a unique identification code. Use the RFID reader 132 to scan the tag, and the reader can quickly identify and read the information in the tag. The RFID reader 132 transmits the read data to the background computer system, and the system automatically counts and records. Compared with the traditional manual inventory method, RFID technology can greatly improve the inventory efficiency. Reduce errors caused by human factors.

[0059] In another embodiment, the RFID reader 132 can also read the RFID tag information attached to the examinee or the object, such as the examinee's identity, the object's attributes, etc. In actual application, when the examinee enters the examination room, the invigilator can use the intelligent safety detector to scan the examinee. The RFID reader 132 will quickly read the RFID tag on the examinee and transmit the information to the controller 4 for processing. In this way, the examinee's identity can be quickly verified to ensure the fairness of the examination.

[0060] Example 2

[0061] This embodiment provides a method for using an intelligent safety detector, which is implemented using the intelligent safety detector applied to the examination field as described above;

[0062] See also Figure 5 , the method comprises the following steps:

[0063] S100, using the first detection mode to detect the person to be detected; this mode may focus on detecting larger metal objects or other common illegal objects. Through this step, the person to be detected who is obviously carrying illegal objects can be quickly screened out.

[0064] S200: When the first detection mode determines that the person to be detected is normal, the second detection mode is used to detect the person to be detected; the second detection mode may have higher sensitivity and accuracy, and can detect smaller and more hidden illegal items. This step is intended to improve the accuracy and reliability of detection and ensure that no potential safety risks are missed.

[0065] S300, processing the detection result through the processor, and automatically recording the detection data and alarm information.

[0066] After completing the detection of the two detection modes, the detection results are processed by the processor. The processor will automatically analyze the detection data, determine whether there is any violation, and automatically record the detection data and alarm information. This step realizes the automation and intelligence of the detection process, and improves work efficiency and accuracy.

[0067] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0068] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0069] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
