Description

Technical Field

[0001] The present invention relates to a management system, and particularly to an anti-cheating examination management system for use in identity recognition and posture monitoring of examinees in an examination room. Background Art

[0002] Traditionally, standardized examinations were paper-based, where examinees gathered in a room and were given paper-based examination materials, usually including a questionnaire booklet and an answer sheet that could be made machine-readable by optical or magnetic means. With the growth of the computer industry and the reduction in the price of computing devices, the field that traditionally disseminated information through paper has begun to shift to electronic means of information dissemination. The field of standardized examinations is no exception, and the use of a computer system to deliver examination questions to users is commonly described as "computer-based testing" (CBT). However, whether it is a traditional paper-based examination or a computer-based examination, there are constantly emerging cheating methods. Today, with a large number of high-tech cheating methods, how to effectively prevent cheating without affecting the examinees' answering of questions has become an urgent problem to be solved. Relying on traditional monitoring systems often cannot completely eliminate the risk of cheating because there are usually dozens of examinees in an examination room, and it is difficult for the back-end and invigilators to effectively identify the status of each examinee. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to overcome the defects in the prior art and provide an anti-cheating examination management system that can collect examination data in multiple aspects, has a high safety factor, a wide coverage range, and diverse identification methods.

[0004] To achieve the above purpose, the present invention provides an anti-cheating examination management system, including multiple examination PC terminals provided at examination stations, an application server, and a back-end storage device; the application server has an in-built examination information database for storing examination items and examinee information, and wirelessly transmits them to the examination stations in the form of examination packages.

[0006] Before the examinee enters the venue and takes a seat, it is necessary to turn on the NFC mobile terminal through fingerprint recognition, connect the NFC mobile terminal and the NFC tag. The examinee wears the NFC mobile terminal to receive relevant examination information and wears it until the end of the examination. If the removal time in the middle is too long, it will be fed back to the data acquisition module in the PC terminal and prompted to the background. In this way, it is possible to prevent examinees from whispering to each other and avoid examinees wearing cheating devices such as wireless earphones.

[0007] Preferably, the application server communicates with multiple examination stations through a distributed network.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by those of ordinary skill in the art, unless the term is otherwise defined. It should be understood that the terms defined in a commonly used dictionary have the same meaning as the terms in the prior art.

[0025] See Figures 1 - 4 , an anti-cheating exam management system, including a plurality of exam PC terminals set at the exam station, as well as an application server and a backend storage device; the application server is built with an exam information database for storing exam items and candidate information, and wirelessly transmits them to the exam station in the form of an exam package, and is characterized in that: it further includes an access control unit set at each exam station; each access control unit is equipped with a corresponding face recognition device; the face recognition device is built with a storage module for receiving candidate registration information; the face recognition device is electrically connected to an electric control lock through a signal transmission module; each of the exam PC terminals is built with a data collection module and externally connected to an NFC mobile terminal; the exam PC terminal is externally connected to an NFC tag; the reader-writer is controlled to open through a fingerprint recognition module; the NFC mobile terminal is built with a pressure sensing unit; the pressure sensing unit controls the on-off state of the NFC mobile terminal and the NFC tag through a controller.

[0026] Furthermore, the exam PC terminal includes an identity recognition module and an exam question answering unit for display and input; the fingerprint recognition module of the NFC tag sends recognition results to the NFC mobile terminal and the identity recognition module respectively; the NFC mobile terminal selects the opening and closing state according to the recognition result; the identity recognition module selects whether to load the subsequent exam question answering unit according to the recognition result.

[0027] In this embodiment, after access control recognition, the NFC mobile terminal will perform secondary identification (fingerprint) on the candidate's identity. If the recognition is successful, the NFC mobile terminal and the NFC tag can achieve wireless communication; at the same time, the NFC mobile terminal sends a recognition success signal to the identity recognition module in the PC terminal, and the computer receives the signal and enters the exam question answering unit.

[0028] In addition, the NFC mobile terminal can also be used to receive examination site information (such as voice prompt information such as remaining exam duration broadcast, foreign language listening broadcast, etc.).

[0029] Specifically, after the NFC mobile terminal is successfully paired with the NFC tag, the examinee must continuously wear the NFC mobile terminal during the exam. If the removal time exceeds the preset threshold, it will be detected by the pressure sensing unit and the signal will be transmitted to the remote control terminal. Since the examinee must wear the NFC mobile terminal during the exam, it is possible to prevent the examinee from wearing other high-tech cheating earphones in the ear canal. At the same time, the NFC mobile terminal uses noise-canceling headphones. Given that the voices of examinees whispering to each other in the examination room are relatively low, and supplemented by noise cancellation, the possibility of examinees communicating with each other during the exam can be greatly reduced.

[0030] Furthermore, the application server communicates with multiple examination stations through a distributed network. In each of the examination stations, a corresponding examination item memory is configured according to the application server, and the examination items are transmitted to the examination item memory or the examination PC in the form of examination packages.

[0031] Furthermore, the NFC mobile terminal is a wireless in-ear headphone; the NFC tag is built-in with a signal source and emits NFC data signals; the NFC mobile terminal is built-in with an NFC module for receiving NFC data signals.

[0032] Furthermore, the controller is arranged inside the NFC tag; the controller is used to receive the real-time signal of the pressure sensor; the controller is connected to the data acquisition module of the examination PC.

[0033] Specifically, in this embodiment, combining the pressure sensor with the wireless headphone is a conventional technical means, which can detect whether the headphone is in the ear canal. After applying this technology to this system, the wireless headphone can play a dual role of receiving and anti-cheating.

[0034] Furthermore, the signal source is an NFC chip, and the NFC chip has security and confidentiality functions, a one-time programmable memory, and a locking mechanism; the NFC chip is used to send on-off instructions to the NFC mobile terminal; the data acquisition module is built-in with a processing unit and a storage unit, and is used to analyze and store the data instruction information sent by the above-mentioned controller to the PC.

[0035] Specifically, in this embodiment, the NFC mobile terminal can be wirelessly connected to a computer through communication protocols such as 2G / 3G / 4G, wifi, etc. It includes an NFC antenna for receiving a signal source after approaching an NFC tag closely; an NFC chip for identifying and analyzing the NFC data signal received by the NFC. The above-mentioned chip is preferably selected from: CC2530, CC2430, etc. CC2530 is a true system-on-chip (SoC) solution for 2.4-GHz IEEE 802.15.4, ZigBee, and RF4CE applications. It can build powerful network nodes at a very low total material cost. CC2530 combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 CPU.

[0036] Furthermore, a data detector is externally connected to the PC terminal for the exam, which is used to collect real-time image data of the human body posture and feedback it to the data analysis module built in the PC terminal.

[0037] Furthermore, the data detector includes a camera and a somatosensory sensor; the somatosensory sensor is wirelessly or wiredly connected to the PC terminal for the exam; the data analysis module is connected to the remote control terminal in a wireless communication manner.

[0038] In this embodiment, the somatosensory sensor adopts a Kinect somatosensory sensor. The abnormal posture model is established by obtaining the candidate's bone point information from the pictures taken by the camera on the somatosensory sensor, and then the candidate's posture is monitored in real time according to the model. Specifically, the characteristic points obtained during the exam are the head, shoulders, hands, etc. According to the spatial positions of the above characteristic points, a normal value range is established. If the real-time data value is greater than the set threshold, it means that the human body deviates from the standard coordinate system and an abnormal position transformation occurs, that is, it means that the candidate may make actions such as turning around or turning the head to whisper to each other. At this time, a warning signal will be sent to the remote control terminal through the PC terminal for the exam.

[0039] In other embodiments, a six-axis sensor can also be used as the data detector, and the JY61 module is adopted for the six-axis sensor. Its measurement ranges are as follows: the linear acceleration is ±16g, the angular acceleration is ±2000° / s, and the angle is ±180°. The measurement errors are: the linear acceleration is 0.01g, and the angular acceleration is 0.05° / s. The acquisition frequency is 10 times / s. Different from the widely used three-axis sensors, this six-axis sensor can integrate the functions of a three-axis accelerometer and a three-axis gyroscope, and simultaneously collect the linear acceleration data and angular acceleration data in three directions, a total of six types of data. The above X, Y, and Z directions are perpendicular to each other, and are respectively the horizontal front-back direction, the horizontal left-right direction, and the vertical direction. Here, the front-back and left-right are both referenced to the human body to be measured. Kalman filtering is performed on the six types of collected data transmitted to the host computer in real time to obtain the filtered data and store it in the background. The Kalman filtering method adopted in this embodiment is a data fusion method, which combines the advantages of ordinary acceleration sensors and gyroscopes, combines the angle obtained from the linear acceleration and the attitude angle obtained by the gyroscope through integral operation, automatically calculates the weights of the two according to statistical laws, and fuses out accurate state values. Analyze the data characteristics presented by various types of data. For each type of data, t (t is an integer greater than 1) data statistical characteristics are selected, and there are a total of t * 6 data statistical characteristics, which are used as conditional attributes for discriminating human postures. Extract the data statistical characteristics of the data sets in various postures to form a sample set. The samples in the sample set are divided into training samples and test samples.

[0040] For example, when the examinee's hands are not on the desktop for a long time, or when the deviation angle of the examinee's body is significantly greater than the normal state, this posture will be determined as a suspicious posture, and a warning will be sent to the remote control terminal.

[0041] Furthermore, the examination PC is equipped with a monitoring component, and the monitoring component is connected to the remote control terminal; the monitoring component is used to obtain the environmental information of the examination PC; the monitoring component has a memory for storing the configuration information of the examination PC.

[0042] Furthermore, the monitoring component has a network adapter independent of the examination PC; the monitoring component is connected to the standard Ethernet / IP network through an Ethernet port; the monitoring component is a board inserted into the PCI slot inside the examination PC and communicates with the examination PC through the bus of the examination PC.

[0043] Specifically, in this embodiment, the monitoring component has a built-in monitoring processor, and the S3C4510B chip is adopted. The chip integrates an Ethernet media access controller internally. Chips such as MPC860 that do not integrate a network adapter can also be used, and are implemented through a separate network adapter chip.

[0044] It can be understood that in this embodiment, a remote monitoring method is adopted to monitor the computer interface, operation status, and usage environment in real time. If the computer is in an abnormal state, such as not being operated for a long time, connecting to the external network, etc., a warning will be sent to the remote control terminal.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
