Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

At present, when a computer is adopted to realize online examination, an examinee is monitored in a software mode, invigilating software cannot automatically display examination terminals connected with invigilating terminals and actual examination terminal positions on a monitoring interface of the invigilating terminals in a one-to-one correspondence mode, the examination terminals connected with the invigilating terminals and the actual examination terminal positions can be displayed on the monitoring interface of the invigilating terminals in a one-to-one correspondence mode only by manually operating the invigilating terminals and all examination terminals by workers, and the examinee on each machine position can be monitored.

The existing steps of positioning the examination terminal in the examination room and monitoring and displaying the interface of the invigilating terminal are as follows: 1) after the examination terminal and the invigilating terminal are connected in an examination room, a worker manually inputs a serial number on an examination program of each examination terminal in sequence, and after the serial number is input, the examination terminal sends the input serial number and the MAC address information of the examination terminal to the invigilating terminal; 2) the invigilating terminal receives the serial number and the MAC address information sent by the examination terminal and displays the serial number and the MAC address information on a screen; 3) the staff manually arranges the corresponding marks of the examination machines displayed on the screen according to the layout of the examination room to realize one-to-one correspondence; 4) in the examination process, the invigilating terminal receives the examination state of the examination terminal and the examination room monitoring video in real time to realize examination room monitoring.

In the above steps, since the invigilation terminal and the examination terminal are arranged in a back direction, if the invigilation terminal and all examination terminals are operated in a manual mode by a worker, a single person cannot give consideration to the invigilation terminal and the examination terminals at the same time, and a lot of time is consumed for completing the positioning of all the examination terminals. Moreover, manual operation by a worker may also introduce human errors, time and labor. Therefore, the embodiment of the invention provides an examination terminal positioning method to solve the technical problems in the prior art.

Fig. 1 is a schematic flowchart of a positioning method of an examination terminal according to an embodiment of the present invention. As shown in fig. 1, the method for positioning an examination terminal according to an embodiment of the present invention includes:

s11, sending a starting instruction to an examination terminal to be positioned in the examination room, and acquiring the examination room monitoring video sent by the starting instruction;

s12, determining the position information of the examination terminal based on the brightness change condition of each block in the examination room monitoring video;

Specifically, in the examination terminal positioning method provided in the embodiment of the present invention, the execution subject may be a server, and the purpose of the method is to position the examination terminal so as to determine the position information of the examination terminal on the screen of the examination monitoring terminal. The server is in communication connection with the invigilating terminal and the examination terminal. The invigilating terminal and the examination terminal can be computers, the invigilating terminal is particularly a computer for monitoring the examination terminal, and examination software is installed in the examination terminal so that an examinee can perform online examination through the examination software.

Step S11 is performed first. When the examination terminal is positioned, the invigilation terminal sends a positioning request to the server, the server sends a starting instruction to the examination terminal to be positioned in the examination room, the examination room can refer to any examination room comprising the examination terminal to be positioned, the examination terminal to be positioned refers to the examination terminal needing to determine the position information of the examination terminal on the screen of the invigilation terminal, and the number of the examination terminals to be positioned in the examination room can be one or more. The starting instruction is sent on the premise that the default test terminal is connected with the server. It should be noted that, for a newly added examination terminal to be positioned in an examination room, the newly added examination terminal to be positioned installs examination software through a local storage installation package, or downloads the examination software through the IP address of a given invigilation terminal. When the examination software is installed through the locally stored installation package, the IP address of the corresponding invigilation terminal needs to be input. After the newly-added examination terminal to be positioned is installed, the examination terminal and the monitoring terminal are connected, and the monitoring terminal also acquires the IP address of the examination terminal. And then, the monitoring terminal sends the acquired IP address of the examination terminal to the server. And the server sends a starting instruction to the corresponding test terminal according to the received IP address.

After a starting-up instruction is sent to the examination terminal to be positioned, the examination room monitoring video sent by the starting-up instruction can be obtained. The examination room monitoring video can be obtained by shooting through a camera device which is arranged in the examination room and faces the screens of all examination terminals, and the camera device is in communication connection with the server and can send the shot examination room monitoring video to the server in real time. The duration of the examination room monitoring video can be set according to the needs, which is not specifically limited in the embodiment of the invention.

Fig. 2 is a schematic diagram of a connection relationship among the examination terminal, the server, the examination monitoring terminal and the camera device according to the embodiment of the present invention. As shown in fig. 2, the examination terminal 21 and the imaging device 22 are connected to a server 23, and the server 23 is connected to a monitoring terminal 24. The server 23 may send a power-on instruction or a power-off instruction to the test terminal 21, and may receive related information returned by the test terminal 21 to implement interaction; the server 23 may receive the examination room monitoring video obtained by the camera 22, and may position each examination terminal in the examination room according to the examination room monitoring video to determine the position information of the examination terminal on the screen of the examination invigilator terminal.

Then, step S12 is executed. And determining the position information of the examination terminal according to the brightness change condition of each block in the examination room monitoring video. Each block in the examination room monitoring video represents an area where the actual position of each examination terminal in the examination room is located, and can be specifically determined by the server through examination terminal distribution information of the examination room. The examination terminal distribution information of the examination room is the actual position distribution information of each examination terminal in the examination room, namely the arrangement of the machine positions in the examination room. For example, there are N test terminals in the test field, and all the test terminals are arranged in m rows and N columns, that is, N — m × N. The distribution information of the examination terminals of the examination room can be obtained by dividing the area of each examination terminal according to a preset area range, and the server can specifically acquire a monitoring video of the examination room through the camera device when the examination room is deployed, and then divide any frame of image of the monitoring video of the examination room to determine the distribution information of the examination terminals of the examination room. After the distribution information of the examination terminals of the examination room is determined, the distribution information of the examination terminals can be mapped to the obtained examination room monitoring video when the examination terminals are positioned, and each block in the examination room monitoring video is obtained.

After the examination room monitoring video sent by the starting instruction is obtained, brightness identification is carried out on the corresponding position of each block in the examination room monitoring video on each frame of image, and the brightness change condition of each block in the examination room monitoring video is determined. The starting instruction can enable the screen of the examination terminal to be changed from dark to bright, so that the position information of the examination terminal on the screen of the invigilation terminal can be determined according to the brightness change condition of each block in the examination room monitoring video.

The examination terminal positioning method provided by the embodiment of the invention comprises the steps of firstly sending a starting-up instruction to an examination terminal to be positioned in an examination room through a server, and acquiring an examination room monitoring video sent by the starting-up instruction; and then determining the position information of the examination terminal according to the brightness change condition of each block in the examination room monitoring video. The whole process does not need manual operation, automatic positioning of the examination terminal can be realized, and the positioning result is more accurate. The problems of large time consumption and operation errors possibly caused by manual operation are solved, the labor input is reduced, and the error rate is reduced.

On the basis of the above embodiment, according to the examination terminal positioning method provided in the embodiment of the present invention, after the server acquires the examination room monitoring video sent by the start instruction, the server may sample the acquired examination room monitoring video, and then perform subsequent processing on the sampled examination room monitoring video, so as to reduce the amount of calculation in the positioning process.

On the basis of the above embodiment, in the examination terminal positioning method provided in the embodiment of the present invention, the server may specifically number each examination terminal in the examination room in sequence after determining the distribution information of the examination terminals in the examination room. For example, the layout of the seats in the examination room is 6 columns and 10 rows, and each examination terminal in the examination room can be numbered sequentially from 1 to 60 in the order of left to right and front to back. After the distribution information of the examination terminals of the examination room is determined, the serial number of each block in the monitoring video of the examination room is the same as the serial number of the corresponding examination terminal in the examination room.

On the basis of the above embodiment, the examination terminal positioning method provided in the embodiment of the present invention is a method for sending a power-on instruction to an examination terminal to be positioned in an examination room, and acquiring an examination room monitoring video sent by the power-on instruction, and specifically includes:

based on a preset instruction sending interval, sending starting instructions to examination terminals to be positioned in the examination room one by one, and acquiring examination room monitoring videos with first preset duration after the starting instructions corresponding to each examination terminal are sent;

Specifically, in the embodiment of the present invention, since the number of the examination terminals to be positioned in the examination field is at least one, in order to ensure the positioning accuracy of each examination terminal to be positioned, the server needs to separately position each examination terminal. When the server executes step S11, in order to avoid being influenced by other examination terminals when positioning a certain examination terminal, a time for the server to send a power-on instruction to each examination terminal may be set, and specifically, a preset instruction sending interval may be set, so that the server sends the power-on instruction to an examination terminal to be positioned in the examination room at regular intervals. The value of the preset instruction sending interval can be set as required, for example, the value of the preset instruction sending interval is 10s, and the test terminals with the numbers of 1 and 2 are to-be-positioned test terminals, so that the starting instruction is sent to the test terminal with the number of 1 at the 1 st s, and the starting instruction is sent to the test terminal with the number of 2 at the 11 th s.

Meanwhile, the positioning accuracy and the positioning cost are comprehensively considered, and the first preset time length which is less than the preset instruction sending interval can be set, so that the server obtains the examination room monitoring video with the first preset time length after the starting instruction is sent, the storage cost of the server can be reduced, and the mutual influence among the examination room monitoring videos corresponding to different examination terminals can be prevented. The value of the first preset duration can be set as required, for example, the value of the first preset duration is 8s, that is, after a power-on instruction is sent to the examination terminal numbered 1 in the 1 st s, the examination room monitoring video in 8s from the 1 st s to the 8 th s is obtained.

In the embodiment of the invention, the preset instruction sending interval and the first preset time length are set, so that the influence of other examination terminals on positioning of a certain examination terminal can be avoided, the positioning accuracy is improved, and the positioning cost is reduced.

On the basis of the above embodiment, the examination terminal positioning method provided in the embodiment of the present invention is a method for determining position information of an examination terminal based on a luminance change condition of each block in the examination room monitoring video, and specifically includes:

Specifically, in the embodiment of the invention, for the current examination terminal to be positioned, the server sends the starting-up instruction to the current examination terminal and acquires the examination room monitoring video sent by the starting-up instruction. And carrying out brightness identification on the corresponding position of each block in the examination room monitoring video on each frame of image, and determining the brightness change condition of each block in the examination room monitoring video. It should be noted that, because the sending of the power-on instruction to the examination terminal to be positioned in the examination room may be sending the power-on instruction to each examination terminal to be positioned one by one at every preset instruction sending interval, when the power-on instruction is sent to a certain examination terminal to be positioned, the examination terminal to be positioned is the current examination terminal, that is, the examination terminal to be positioned needs to send the power-on instruction to the examination terminal to be positioned at the current time for positioning. The last test terminal of the current test terminal is the object pointed by the last startup instruction sent before the startup instruction is sent to the current test terminal.

If a block with changed brightness exists in the examination room monitoring video corresponding to the current examination terminal, the position information of the block with changed brightness in the examination room monitoring video can be used as the position information of the current examination terminal, that is, the position information of the current examination terminal can be determined to be the position information of the block with changed brightness in the examination room monitoring video.

If there is no block with brightness change in the examination room monitoring video corresponding to the current examination terminal, it is indicated that the current examination terminal and the screen of the examination terminal which has sent the power-on instruction but has not been positioned by the server before the power-on instruction are not lit up, so that the position information of the current examination terminal cannot be determined, and at this time, the position information of the current examination terminal can be determined to be empty, that is, the current examination terminal is not positioned successfully at this time.

In the embodiment of the invention, the position information of the current examination terminal is determined by judging whether a block with changed brightness exists in the examination room monitoring video corresponding to the current examination terminal and combining whether the position information of the last examination terminal of the current examination terminal is empty, so that the position information of the current examination terminal can be determined more intuitively and quickly.

On the basis of the above embodiment, the examination terminal positioning method provided in the embodiment of the present invention is configured to determine that location information of a block with a luminance change in an examination room monitoring video corresponding to a current examination terminal is location information of the current examination terminal if it is determined that the block with the luminance change exists in the examination room monitoring video, and specifically includes:

Specifically, in the embodiment of the present invention, for a current examination terminal to be positioned, after the server determines a luminance change condition of each block in an examination room monitoring video, under the condition that a block with a luminance change exists in the examination room monitoring video corresponding to the current examination terminal, on one hand, the position information of the last examination terminal of the current examination terminal is not null, that is, the last examination terminal is a normal terminal, and positioning can be performed, and the position information of the last examination terminal is determined, a block with a luminance change in the examination room monitoring video corresponding to the current examination terminal cannot be caused by a delayed response of the last examination terminal, that is, a block with a luminance change does not exist in the examination room monitoring video acquired by the server after sending a power-on instruction to the current examination terminal. On the other hand, the previous examination terminal is an abnormal terminal, which indicates that no block with brightness change corresponding to the previous examination terminal exists in the examination room monitoring video acquired after the server sends the power-on instruction to the previous examination terminal. In the two aspects, the starting-up instruction sent by the server to the previous examination terminal does not influence the examination room monitoring video obtained after the starting-up instruction is sent to the current examination terminal. At this time, if a block with changed brightness exists in the examination room monitoring video corresponding to the current examination terminal, the position information of the block is certain to be the position information of the current examination terminal. The location information of the block refers to the location of the block.

In the embodiment of the invention, aiming at the condition that delayed response may occur to the examination terminal, if a block with changed brightness exists in an examination room monitoring video corresponding to the current examination terminal and the position information of the previous examination terminal is not empty, the position information of the block with changed brightness in the examination room monitoring video is determined to be the position information of the current examination terminal, so that the misjudgment of the position information can be reduced, and the accuracy of the position information of the current examination terminal is improved.

If a block with brightness change exists in the examination room monitoring video corresponding to the current examination terminal and the position information of the last examination terminal of the current examination terminal is null, it is indicated that the block with brightness change existing in the examination room monitoring video corresponding to the current examination terminal is likely to correspond to the current examination terminal and is also likely to correspond to the last examination terminal with delayed response. At the moment, a shutdown instruction is sent to the current examination terminal, and a shutdown monitoring video with the duration of a second preset duration after the shutdown instruction is sent is obtained. The server sends a starting instruction to the previous examination terminal of the current examination terminal, but the screen of the previous examination terminal is not lighted up and positioning is not achieved, so that the position information of the previous examination terminal cannot be determined, at the moment, the position information of the previous examination terminal can be determined to be empty, namely, the previous examination terminal is not positioned successfully at the moment.

The current examination terminal can be changed from bright to dark under the action of the shutdown instruction, so that whether a block with changed brightness exists in the shutdown monitoring video needs to be judged, and if the block with changed brightness exists in the shutdown monitoring video, the position information of the block is the position information of the current examination terminal. If the block with the brightness change does not exist in the shutdown monitoring video, the brightness change of the block with the brightness change existing in the examination room monitoring video corresponding to the current examination terminal is irrelevant to the shutdown of the current examination terminal and is caused by the delayed lighting of the screen of the previous examination terminal, and therefore the position information of the block is the position information of the previous examination terminal.

This is because, if a block with brightness change in the examination room monitoring video corresponds to the current examination terminal, it indicates that the delay of the current examination terminal in receiving and responding to the instruction is within the monitorable range. In this case, if a shutdown instruction is sent to the current test terminal, there may be a case where a block in which a luminance change cannot be detected in the shutdown monitoring video due to delay in reception and response of the current test terminal to the shutdown instruction. Therefore, when detecting whether a block with brightness change exists in the shutdown monitoring video, the response delay problem of the current examination terminal needs to be considered, and if the block with brightness change cannot be detected, the position information of the block with brightness change in the examination room monitoring video can be directly used as the position information of the last examination terminal.

In the embodiment of the invention, under the condition that a block with changed brightness exists in the examination room monitoring video corresponding to the current examination terminal, the condition that the position information of the last examination terminal of the current examination terminal is empty is considered, further analysis is carried out, and the position information of the current examination terminal or the last examination terminal is determined, so that the position information of the current examination terminal can be determined more intuitively and quickly, and the position information of the last examination terminal of the current examination terminal can be determined under certain conditions.

On the basis of the above embodiment, the examination terminal positioning method provided in the embodiment of the present invention is a method for determining position information of an examination terminal based on a luminance change condition of each block in the examination room monitoring video, further including:

if the fact that at least two blocks with changed brightness exist in the examination room monitoring video corresponding to the current examination terminal is obtained through judgment, the preset instruction sending interval and the first preset duration are adjusted, all examination terminals to be positioned in the examination room are shut down, and on the basis of the adjusted preset instruction sending interval, the examination terminals to be positioned in the examination room are linearly sent with the starting instructions one by one again until the starting instructions are sent to all examination terminals to be positioned in the examination room, and at least two blocks with changed brightness do not exist in the examination room monitoring video corresponding to any examination terminal.

Specifically, in the embodiment of the present invention, for the current examination terminal to be positioned, after the server determines the brightness change condition of each block in the examination room monitoring video, if at least two blocks with changed brightness exist in the examination room monitoring video corresponding to the current examination terminal, it is indicated that the position information of the current examination terminal may exist in the positions of the blocks, or the position information of the current examination terminal may not exist, and all of the positions are caused by delayed lighting of the screen of the previous examination terminal to be positioned. At this time, the preset instruction sending interval and the first preset time length need to be adjusted, and the preset instruction sending interval and the first preset time length may be specifically increased. And then all examination terminals to be positioned in the current examination room are shut down, the server sends the starting instructions to the examination terminals one by one according to the adjusted preset instruction sending interval, the examination room monitoring video with the time length being the adjusted first preset time length is obtained through the camera device, a new round of positioning process is executed until the starting instructions are sent to all examination terminals to be positioned in the examination room, and at least two blocks with changed brightness do not exist in the examination room monitoring video corresponding to any examination terminal. All examination terminals to be positioned in the current examination room are shut down, and the automatic shutdown can be realized by manually shutting down the examination terminals or sending shutdown instructions to all examination terminals to be positioned in the current examination room through the server. When the preset instruction sending interval and the first preset duration are adjusted, as an optimal scheme, the preset instruction sending interval and the first preset duration may be adjusted to be at least twice of the original intervals respectively.

In the embodiment of the invention, the condition that at least two blocks with changed brightness exist in the examination room monitoring video corresponding to the current examination terminal is considered, the sending interval of the preset instruction and the first preset time length are adjusted, all examination terminals to be positioned in the examination room are shut down, the starting instructions are sent to all examination terminals to be positioned one by one again according to the adjusted sending interval of the preset instruction, and the examination terminals to be positioned in the examination room are positioned for a new round. The automatic positioning of the examination terminals can be ensured to be realized through the server as many as possible.

On the basis of the embodiment, the server sends a starting-up instruction to the test terminal, and the corresponding MAC address information is sent to the server for storage when the test terminal is normally started. At this time, after the position information of the test terminal is determined, the server may also bind the serial number of the corresponding block and the MAC address information, and store the serial number and the MAC address information in the server together. The server can send the stored binding relationship to the invigilation terminal, so that the examination terminal identification is displayed on the screen of the invigilation terminal. The examination terminal identifier may specifically include a serial number and MAC address information of a block in the binding relationship, and may further include a uniform style icon of the examination terminal.

On the basis of the above embodiment, the examination terminal positioning method provided in the embodiment of the present invention, after determining the position information of the examination terminal based on the luminance change condition of each block in the examination room monitoring video, further includes:

Specifically, in the embodiment of the present invention, after the position information of all the examination terminals in the examination room is determined, that is, after the server sends the power-on instruction to all the examination terminals, each examination terminal has one corresponding position information, where the position information may be null or not null, and if the position information is not null, the positioning is successful, and if the position information is null, the positioning is failed, so that the examination terminal whose position information is null needs to be marked as an abnormal terminal, and the abnormal reason of the abnormal terminal needs to be continuously determined.

Because the server sends the starting-up instruction to the test terminal, the corresponding MAC address information is sent to the server for storage when the test terminal is normally started. Moreover, under normal conditions, interaction is realized between the server and the test terminal through IP connection, so that the judgment of the abnormal reason of the abnormal terminal can be realized through the following steps:

and after the server sends a starting-up instruction to the abnormal terminal, judging whether response information returned by the abnormal terminal is received or not, and determining the difference value between the total number of all the examination terminals in the examination room and the total number of the connected examination terminals. The response information may include MAC address information of the abnormal terminal, and the connected test terminal is a test terminal connected to the server in the IP.

Based on the judgment result and the difference value, the abnormal reason of the abnormal terminal can be determined. The abnormal reasons can be specifically divided into unlighted, unlighted and unlinked, wherein unlighted means that response information returned by the abnormal terminal can be received, but the screen of the abnormal terminal is unlighted, that is, a block with no brightness change exists in the examination room monitoring video corresponding to the abnormal terminal. The non-startup means that no response information returned by the abnormal terminal is received, and meanwhile, the screen of the abnormal terminal is not lighted up, that is, the abnormal terminal does not receive the starting-up instruction sent by the server. The unconnected state means that the difference value between the total number of all the examination terminals in the examination room and the total number of the connected examination terminals is larger than 0, the unconnected examination terminals are all abnormal terminals at the moment, and the abnormal reasons are all unconnected.

On the basis, the server can control the monitoring terminal to display different prompt messages according to the abnormal reason of the abnormal terminal. For example, when the abnormal reason is not lighted, the server can control the monitoring terminal to display prompt information for prompting the screen condition of the abnormal terminal to be checked manually; when the abnormal reason is not started, the server can control the monitoring terminal to display prompt information for prompting whether the network or the connection between the abnormal terminal and the server is stable or not for manual checking; when the abnormal reason is not connected, the server can control the monitoring terminal to display prompt information and the like for prompting whether the examination software on the abnormal terminal is normally installed or not.

In the embodiment of the invention, the examination terminal which is not successfully positioned is marked as the abnormal terminal, and the abnormal reason of the abnormal terminal is judged, so that the follow-up inspection and maintenance of the abnormal terminal can be helped.

Specifically, in the embodiment of the present invention, when determining the position information of the examination terminal according to the brightness change condition of each block in the examination room monitoring video, the user block marked by the user for the examination terminal may be received, that is, the user may mark the position information of the examination terminal corresponding to the power-on instruction on the user input device manually, and mark the position information as the user block. The marking mode of the user block can be a mode that a user drags and selects a certain block in the screen of the invigilation terminal through a mouse, and can also be realized by setting a window with a fixed size and collecting the window on different blocks in the screen of the invigilation terminal through the user. Note that the window size may not span two blocks.

The server judges whether the position information of the automatically determined examination terminal is consistent with the user block, the specific judgment method is to determine the identification information of the block corresponding to the position information of the examination terminal, compare the identification information with the identification information of the user block, if the two are consistent, the position information of the automatically determined examination terminal of the server is consistent with the user block, otherwise, the position information of the automatically determined examination terminal of the server is inconsistent with the user block. The judging method can also be that the position information of the user block is determined, the position information is compared with the position information of the examination terminal automatically determined by the server, if the position information is consistent with the position information of the examination terminal automatically determined by the server, the position information of the examination terminal automatically determined by the server is consistent with the user block, and if not, the position information of the examination terminal automatically determined by the server is inconsistent with the position information of the user block.

And if the server judges that the results are inconsistent, sending block prompt information comprising the position information of the examination terminal and the user blocks to a user terminal held by the user for the user to select on the user terminal and feeding back to the server. The feedback information is confirmation information for confirming the final position information of the examination terminal. The server receives the confirmation information and updates the position information of the examination terminal with the final position information contained in the confirmation information.

In the embodiment of the invention, the processes of manual selection and manual confirmation are introduced, so that man-machine combination is realized, the positioning result is more accurate, and the automatic positioning error of the server is avoided.

Specifically, in the examination terminal monitoring method provided in the embodiment of the present invention, the execution main body is the server, and the server monitors the examination state of the examination terminal in the examination process.

First, step S31 is executed, during the examination, the invigilating terminal sends invigilating request to the server, and the server uniformly starts all the examination terminals. And the server receives the state identification returned by each test terminal in real time and determines the state information of each test terminal based on the state identification. The state identifier is used for identifying state information of the examination terminal, and can be specifically represented as a state code. The state information of the test terminal refers to test state information and may include a normal state and an abnormal state. The normal state refers to a state in which the test terminal can provide a normal test for the examinee, and the abnormal state may include unconnected state, hardware falling-off state, test suspension, data abnormality, test failure and the like. In the embodiment of the present invention, the status flag of the unconnected abnormal status may be set to be gray, and the status flags of the other abnormal statuses are red.

And after receiving the state identifier, the server analyzes the state identifier, wherein the analyzing process is a process of determining the state information according to the state identifier. Therefore, a correspondence between the state identification and the state information may be stored in the server. And after receiving the state identification, searching the corresponding state information through the corresponding relation.

Then, step S32 is executed, in which the server transmits the state information of each test terminal to the invigilation terminal, and the invigilation terminal dynamically displays the state information of each test terminal at the position of each test terminal in real time according to the position information of each test terminal in the examination room. It should be noted that the status information may carry a unique identifier, such as an MAC address, and the display area of the examination terminal on the monitoring terminal is determined according to the correspondence between the MAC address and the blocks in the monitoring video of the examination room, so as to display the corresponding status information in the corresponding area.

On the basis, abnormal state reminding can be carried out. The position information of each test terminal in the examination room is determined by the test terminal positioning method provided in the embodiment.

Meanwhile, the shooting device can transmit the examination room monitoring video obtained through shooting to the invigilating terminal in real time, and the examination room monitoring video and the state information of the examination terminal are displayed together through the invigilating terminal.
