Description

Technical Field

[0001] The present invention relates to the technical field of audio and video communication supervision, and in particular to an online audio and video communication management system suitable for judicial procedures. Background Art

[0002] In the judicial process, especially when hearing a case in court, witness testimony and lawyer defense often require face-to-face communication, which not only increases the workload of the court, but also makes the court hearing too long. Due to geographical and time factors, the court is often unable to guarantee the participation of all relevant personnel, making the trial results prone to disputes. Therefore, communication technology has been gradually applied to court case hearings. By sending the court's online audio and video to the receiving end, relevant personnel outside the court can participate in the court hearing;

[0003] However, when managing the communication of the court's online audio and video, it is impossible to reasonably analyze and accurately evaluate the use risks of all receiving ends before audio and video transmission, and it is difficult to ensure that all connected receiving ends are in a low-risk state. In addition, it is difficult to evaluate the network status of the connected receiving end and accurately judge the abnormal transmission status of online audio and video during audio and video transmission, which increases the difficulty of communication management of the court's online audio and video, and is not conducive to ensuring the security and stability of the court's online audio and video transmission;

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0005] The purpose of the present invention is to provide an online audio and video communication management system suitable for judicial procedures, which solves the problems that the prior art is unable to reasonably analyze and accurately evaluate the usage risks of all receiving ends before online audio and video transmission in the court, and it is difficult to evaluate the network status of the connected receiving end and accurately judge the abnormal transmission status of the online audio and video during audio and video transmission, and the communication management is difficult and the degree of intelligence is low.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An online audio and video communication management system suitable for judicial procedures, comprising a communication management platform, a court audio and video acquisition module, a trusted terminal network condition detection module, an audio and video transmission supervision module and a background supervision terminal; the court audio and video acquisition module is used to collect voice and video information of court-related personnel, and digitize the collected information, and send the digitized audio and video information to the corresponding trusted terminal outside the court through the communication management platform and the Internet, and the trusted terminal displays the audio and video information to the corresponding trusted personnel;

[0008] When the trusted terminal displays audio and video information, the trusted terminal network status detection module detects the network status of the corresponding trusted terminal, marks the corresponding trusted terminal as a network stable terminal or a network abnormal terminal through analysis, and sends the marking information of the corresponding trusted terminal to the intelligent terminal of the corresponding trusted personnel through the communication management platform; the audio and video transmission supervision module monitors the audio and video display effects of all network stable terminals, and generates a transmission stable signal or a transmission abnormality signal through analysis, and sends the transmission abnormality signal to the background warning terminal through the communication management platform. The background warning terminal issues a corresponding warning when receiving the transmission abnormality signal.

[0009] Furthermore, the communication management platform is communicatively connected with the registration and login verification module, which is used to register personnel, mark the successfully registered personnel as trusted personnel, and send the identity information of the trusted personnel to the communication management platform for storage; and authenticate the trusted personnel when they log in, and allow them to log in and receive the court's online audio and video information after the identity authentication is correct.

[0010] Furthermore, the registration login verification module is also used to register out-of-court audio and video receiving terminals, and mark the successfully registered out-of-court audio and video receiving terminals as trusted terminals, and send the device information of the trusted terminals to the communication management platform; and when the corresponding trusted personnel log in through the corresponding trusted terminal, the registration login verification module obtains the device information of the trusted terminal. If the obtained device information is consistent with the corresponding device information stored in the communication management platform, the trusted terminal is allowed to access the communication management platform and receive the court's online audio and video information.

[0011] Furthermore, the communication management platform is connected to the trusted terminal pre-assessment module for communication. The trusted terminal pre-assessment module obtains all trusted terminals and marks the corresponding trusted terminal as i; collects the production interval time and the total usage time of the trusted terminal i, and compares the production interval time and the total usage time with the corresponding preset production interval time threshold and the preset total usage time threshold, respectively. If the production interval time or the total usage time exceeds the corresponding preset threshold, a high-risk signal for the use of the trusted terminal i is generated;

[0012] If both the production interval duration and the total usage duration do not exceed the corresponding preset thresholds, the preset production interval duration threshold is subtracted from the production interval duration to obtain the production interval time difference, and the preset total usage duration threshold is subtracted from the total usage duration to obtain the total usage time difference value; and when the trusted terminal i is impacted by an external force, the maximum impact force, the average impact force and the duration of the impact of the corresponding external force impact process are collected, and the maximum impact force, the average impact force and the duration of the impact are numerically calculated to obtain the external force detection value, and the external force detection value is numerically compared with the preset external force detection threshold. If the external force detection value exceeds the preset external force detection threshold, the corresponding external force impact process is marked as an external force high-loss process;

[0013] The number of external force high-loss processes involving trusted terminal i in the historical stage is obtained and marked as the external force high-loss frequency, and the total time that the trusted terminal i is in the terminal ring loss state in the historical stage is obtained and marked as the terminal ring loss time inspection value; the production interval time difference, the total use time difference value, the external force high-loss frequency and the terminal ring loss time inspection value are numerically calculated to obtain the trusted terminal traceability value, and the trusted terminal traceability value is numerically compared with the preset trusted terminal traceability threshold. If the trusted terminal traceability value exceeds the preset trusted terminal traceability threshold, a high-risk signal for the use of the trusted terminal i is generated.

[0014] Furthermore, if the trusted terminal tracing value does not exceed the preset trusted terminal tracing threshold, a terminal evaluation period is set, the number of times the trusted terminal i is attacked by network attacks and virus intrusions during the terminal evaluation period is collected and marked as the terminal network loss frequency analysis value, and the duration of the impact of the trusted terminal i by network attacks and virus intrusions during the terminal evaluation period is collected and marked as the terminal network loss time analysis value;

[0015] The terminal network loss frequency analysis value and the terminal network loss time analysis value are numerically compared with the preset terminal network loss frequency analysis threshold and the preset terminal network loss time analysis threshold respectively. If the terminal network loss frequency analysis value or the terminal network loss time analysis value exceeds the corresponding preset threshold, a high-risk signal for the use of the trusted terminal i is generated; if both the terminal network loss frequency analysis value and the terminal network loss time analysis value do not exceed the corresponding preset threshold, a low-risk signal for the use of the trusted terminal i is generated; and the high-risk signal or the low-risk signal for the use of the trusted terminal i is sent to the background supervision end via the communication management platform.

[0016] Furthermore, the communication management platform is connected to the trusted terminal operation and environment detection module in communication. The trusted terminal operation and environment detection module detects and analyzes the environment of the trusted terminal i, collects the real-time temperature, real-time humidity and environmental pH of the environment of the trusted terminal i, calculates the difference between the real-time temperature and the median of the preset suitable real-time temperature range, and takes the absolute value to obtain the terminal temperature deviation value. Similarly, the terminal humidity deviation value and the pH deviation value are obtained;

[0017] The dust concentration of the environment in which the trusted terminal i is located is collected and marked as a dust detection value, the terminal temperature deviation value, the terminal humidity deviation value, the pH deviation value and the dust detection value are numerically calculated to obtain a terminal environment inspection value, and the terminal environment inspection value is numerically compared with a preset terminal environment inspection threshold value. If the terminal environment inspection value exceeds the preset terminal environment inspection threshold value, it is determined that the trusted terminal i is in a terminal ring damage state. When it is determined that the trusted terminal i is in a terminal ring damage state, corresponding warning information is generated and sent to the intelligent terminal of the corresponding trusted personnel via the communication management platform.

[0018] Furthermore, the specific operation process of the trusted terminal network status detection module is as follows:

[0019] Collect the network bandwidth data of the corresponding trusted terminal in several detection periods within a unit time, mark the deviation value of the network bandwidth data compared with the preset appropriate network bandwidth standard value as the network bandwidth deviation value, calculate the average of all network bandwidth deviation values ​​to obtain the terminal network bandwidth detection value, and mark the proportion of the number of detection periods in which the network bandwidth deviation value exceeds the preset network bandwidth deviation threshold as the terminal network bandwidth deviation value;

[0020] and collecting the network speed curve of the corresponding trusted terminal in unit time, placing the network speed curve in a rectangular coordinate system located in the first quadrant, wherein the X-axis of the rectangular coordinate system represents time, the Y-axis represents network speed, and the starting point of the network speed curve is located on the Y-axis; making a network speed standard ray parallel to the X-axis and with its endpoint located on the Y-axis in the rectangular coordinate system, marking the portion of the network speed curve located below the network speed standard ray and the area enclosed by the network speed standard ray as the terminal network speed low detection value;

[0021] And all trough points in the network speed curve are obtained, the network speeds of all trough points are summed up and the average is taken to obtain the terminal network speed trough value; the terminal network speed trough value, the terminal network speed low detection value, the terminal network band detection value and the terminal network band deviation value are numerically calculated to obtain the trusted terminal network condition value, and the trusted terminal network condition value is numerically compared with the preset trusted terminal network condition threshold value. If the trusted terminal network condition value exceeds the preset trusted terminal network condition threshold value, the corresponding trusted terminal is marked as a network abnormal terminal; if the trusted terminal network condition value does not exceed the preset trusted terminal network condition threshold value, the corresponding trusted terminal is marked as a network stable terminal.

[0022] Furthermore, the specific operation process of the audio and video transmission supervision module includes:

[0023] All network-stable terminals within a unit time are acquired, the audio and video delay duration of the corresponding network-stable terminal is collected, as well as the freeze frequency and each freeze duration when the corresponding network-stable terminal performs audio and video display within a unit time, and all freeze durations are summed up to obtain the total freeze duration; and when the output of the audio information and the video information of the corresponding network-stable terminal is inconsistent, it is judged that the corresponding moment is in the state of audio and video docking error, the duration of the corresponding network-stable terminal in the state of audio and video docking error within a unit time is acquired and marked as the total audio and video output error duration; the audio and video delay duration, freeze frequency, total freeze duration and total audio and video output error duration are numerically calculated to obtain the terminal exhibition effectiveness value, and the terminal exhibition effectiveness value is numerically compared with the preset terminal exhibition effectiveness threshold. If the terminal exhibition effectiveness value exceeds the preset terminal exhibition effectiveness threshold, the corresponding network-stable terminal is marked as a poor exhibition terminal;

[0024] The number of terminals with poor display is marked as a poor display analysis value, the ratio of the poor display analysis value to the number of stable terminals is marked as a poor display percentage value, the terminal display effectiveness values ​​of all stable terminals in a unit time are averaged to obtain a terminal display value, the poor display analysis value, the poor display percentage value and the terminal display value are numerically calculated to obtain an audio and video transmission value, the audio and video transmission value is numerically compared with a preset audio and video transmission threshold, and if the audio and video transmission value exceeds the preset audio and video transmission threshold, a transmission abnormality signal is generated;

[0025] If the audio and video analysis value does not exceed the preset audio and video analysis threshold, the packet loss rate of the audio and video transmission process per unit time is collected, and the packet loss rate is numerically compared with the preset packet loss rate threshold. If the packet loss rate exceeds the preset packet loss rate threshold, a transmission abnormality signal is generated; if the packet loss rate does not exceed the preset packet loss rate threshold, a transmission normal signal is generated.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In the present invention, the registration and login module is used to register personnel and the off-court audio and video receiving terminal, and is used for the login access verification of trusted personnel and trusted terminals, which is conducive to ensuring the transmission security of online audio and video in the court. The trusted terminal operation environment detection module is used to detect and analyze the environment of the trusted terminal and determine whether it is in a terminal environment loss state, which is convenient for timely environmental regulation and provides data support for the analysis process of the trusted terminal pre-assessment module. In addition, the trusted terminal pre-assessment module is used to reasonably analyze and accurately evaluate the use risk of the trusted terminal to be connected before audio and video transmission, ensuring that the connected trusted terminals are in a low-risk state, further improving the transmission security of online audio and video in the court;

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1: Figure 1 As shown, the present invention proposes an online audio and video communication management system suitable for judicial procedures, including a communication management platform, a registration and login verification module, a court audio and video acquisition module, a trusted terminal network condition detection module, an audio and video transmission supervision module and a background supervision terminal; the registration and login module is used to register personnel, and the successfully registered personnel are marked as trusted personnel, and the identity information of the trusted personnel is sent to the communication management platform for storage, wherein the identity information of the trusted personnel includes name, gender, occupation, age, ID number and contact information, etc.; and identity authentication is performed on the trusted personnel when they log in, and the identity authentication methods include password verification, mobile phone verification code verification and fingerprint verification, etc. After the identity authentication is correct, they are allowed to log in and receive the court's online audio and video information, which helps to ensure the communication security of the court's online audio and video.

[0034] The registration and login verification module is also used to register out-of-court audio and video receiving terminals, and the successfully registered out-of-court audio and video receiving terminals are marked as trusted terminals, and the device information of the trusted terminals is sent to the communication management platform; wherein, the device information of the trusted terminal includes the device model, device life, device production date, etc.; and when the corresponding trusted personnel log in through the corresponding trusted terminal, the registration and login verification module obtains the device information of the trusted terminal. If the obtained device information is consistent with the corresponding device information stored in the communication management platform, the trusted terminal is allowed to access the communication management platform and receive the court's online audio and video information, further ensuring the communication security of the court's online audio and video.

[0035] The court audio and video acquisition module is used to collect voice and video information of court-related personnel, and digitize the collected information. The digitized audio and video information is sent to the corresponding trusted terminal outside the court through the communication management platform and the Internet. The trusted terminal displays the audio and video information to the corresponding trusted personnel;

[0036] When the trusted terminal displays audio and video information, the trusted terminal network status detection module detects the network status of the corresponding trusted terminal, marks the corresponding trusted terminal as a stable terminal or a network abnormal terminal through analysis, and sends the marking information of the corresponding trusted terminal to the intelligent terminal of the corresponding trusted personnel through the communication management platform. The corresponding trusted personnel promptly conducts network inspection and regulation of the network abnormal terminal to improve the stability and fluency of the received court online audio and video; the specific operation process of the trusted terminal network status detection module is as follows:

[0037] Collect network bandwidth data of a number of detection periods of the corresponding trusted terminal in a unit time, mark the deviation value of the network bandwidth data compared with the preset appropriate network bandwidth standard value as the network bandwidth deviation value, calculate the average of all network bandwidth deviation values ​​to obtain the terminal network bandwidth detection value, and mark the proportion of the number of detection periods in which the network bandwidth deviation value exceeds the preset network bandwidth deviation threshold as the terminal network bandwidth deviation time value; wherein, the larger the values ​​of the terminal network bandwidth detection value and the terminal network bandwidth deviation time value, the worse the network condition of the corresponding trusted terminal in a unit time;

[0038] And collect the network speed curve of the corresponding trusted terminal in unit time, put the network speed curve into a rectangular coordinate system located in the first quadrant, the X-axis of the rectangular coordinate system represents time, the Y-axis represents network speed, and the starting point of the network speed curve is located on the Y-axis; make a network speed standard ray parallel to the X-axis and with its endpoint on the Y-axis in the rectangular coordinate system, mark the part of the network speed curve located below the network speed standard ray and the area surrounded by the network speed standard ray as the terminal network speed low detection value; and obtain all the trough points in the network speed curve, sum and calculate the network speeds of all the trough points and take the average to obtain the terminal network speed trough value;

[0039] By formula TX = (fy2 TK+fy3 TF+fy4 TP) / (fy1 TG+fy2) The terminal network speed valley value TG, the terminal network speed low detection value TK, the terminal network band detection value TF and the terminal network band deviation value TP are numerically calculated to obtain the trusted terminal network condition value TX, wherein fy1, fy2, fy3, fy4 are preset proportional coefficients, and the values ​​of fy1, fy2, fy3, fy4 are all greater than zero; and the larger the value of the trusted terminal network condition value TX is, the worse the network performance of the corresponding trusted terminal is in unit time;

[0040] The trusted terminal network condition value TX is numerically compared with the preset trusted terminal network condition threshold. If the trusted terminal network condition value TX exceeds the preset trusted terminal network condition threshold, indicating that the network performance of the corresponding trusted terminal in unit time is poor, the corresponding trusted terminal is marked as a network abnormal terminal; if the trusted terminal network condition value TX does not exceed the preset trusted terminal network condition threshold, indicating that the network performance of the corresponding trusted terminal in unit time is good, the corresponding trusted terminal is marked as a network stable terminal.

[0041] The audio and video transmission supervision module monitors the audio and video display effects of all network terminals, and generates transmission stability signals or transmission abnormality signals through analysis, and sends the transmission abnormality signals to the background warning terminal through the communication management platform. When the background warning terminal receives the transmission abnormality signal, it issues a corresponding warning, which facilitates the management personnel to timely investigate, trace and diagnose the causes of online audio and video transmission abnormalities, and take corresponding targeted control measures in a timely manner, so as to ensure the transmission stability and transmission quality of the court's online audio and video; the specific operation process of the audio and video transmission supervision module includes:

[0042] All network-stable terminals within a unit time are obtained, the audio and video delay duration of the corresponding network-stable terminal is collected, and the freeze frequency and each freeze duration when the corresponding network-stable terminal performs audio and video display within a unit time are collected, and all freeze durations are summed up to calculate the total freeze duration; and when the output of the audio information and video information of the corresponding network-stable terminal is inconsistent (that is, the audio information and the video image information at the corresponding moment are not aligned), it is judged that the corresponding moment is in an audio and video connection error state, and the duration of the corresponding network-stable terminal in the audio and video connection error state within the unit time is obtained and marked as the total audio and video output error duration;

[0043] By formula The audio and video delay time FW, the freeze frequency FY, the total freeze time FQ and the total audio and video input difference time FS are numerically calculated to obtain the terminal display effect value FK, where sg1, sg2, sg3, and sg4 are preset proportional coefficients, and the values ​​of sg1, sg2, sg3, and sg4 are all positive numbers; and the larger the value of the terminal display effect value FK, the worse the audio and video display effect of the corresponding trusted terminal in unit time;

[0044] The terminal exhibition effectiveness value FK is numerically compared with the preset terminal exhibition effectiveness threshold. If the terminal exhibition effectiveness value exceeds the preset terminal exhibition effectiveness threshold, it indicates that the audio and video display effect of the corresponding trusted terminal in unit time is poor, and the corresponding network-stable terminal is marked as a poor exhibition terminal; the number of poor exhibition terminals is marked as a poor exhibition number analysis value, and the ratio of the poor exhibition number analysis value to the number of network-stable terminals is marked as a poor exhibition number ratio value. The terminal exhibition effectiveness values ​​of all network-stable terminals in unit time are averaged to obtain the terminal exhibition table value;

[0045] By the formula YF=wq1 YP+wq2 YK+wq3 YW / (wq1+wq2) numerically calculates the display poor number analysis value YP, the display poor number ratio value YK and the terminal display table value YW to obtain the audio and video analysis value YF, wherein wq1, wq2 and wq3 are preset proportional coefficients, wq2>wq1>wq3>0.26; and the larger the value of the audio and video analysis value YF is, the worse the transmission quality of the court's online audio and video per unit time is; the audio and video analysis value YF is numerically compared with the preset audio and video analysis threshold value, if the audio and video analysis value YF exceeds the preset audio and video analysis threshold value, it indicates that the transmission quality of the court's online audio and video per unit time is poor, and a transmission abnormality signal is generated;

[0046] If the audio and video analysis value YF does not exceed the preset audio and video analysis threshold, the packet loss rate of the audio and video in the network transmission process per unit time is collected. The packet loss rate refers to the proportion of data packets lost in the network transmission process. The packet loss rate directly affects the stability of audio and video communication. The packet loss rate is numerically compared with the preset packet loss rate threshold. If the packet loss rate exceeds the preset packet loss rate threshold, it indicates that the transmission quality of the court's online audio and video per unit time is poor, and a transmission abnormality signal is generated. If the packet loss rate does not exceed the preset packet loss rate threshold, it indicates that the transmission quality of the court's online audio and video per unit time is good, and a transmission normal signal is generated.

[0047] Preferably, the present invention can also have the function of initiating online trials for multiple applications, and push information to each applicant and respondent. At the same time, the key information of each case generates complete trial scripts with the assistance of intelligent voice. After both parties receive the information push, they can participate in the online trial by completing the biopsy certification at the specified time. When there is no intervention from both parties online, the intelligent voice will perform voice broadcasts and prompts according to the process, and finally complete the overall process through online signing, realizing a one-to-many video scene, with online biopsy authentication and intelligent voice assistance to provide corresponding audio information, reducing the complex online communication environment, and realizing one-to-one face-to-face communication online, speeding up the overall execution process efficiency.

[0048] Embodiment 2: Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the communication management platform is connected to the trusted terminal operation and environment detection module in communication, and the trusted terminal operation and environment detection module detects and analyzes the environment where the trusted terminal i is located, collects the real-time temperature, real-time humidity and environmental pH of the environment where the trusted terminal i is located, calculates the difference between the real-time temperature and the median of the preset suitable real-time temperature range and takes the absolute value to obtain the terminal temperature deviation value, and similarly obtains the terminal humidity deviation value and the pH deviation value, and collects the dust concentration of the environment where the trusted terminal i is located and marks it as the dust detection value;

[0049] By formula The terminal temperature deviation value ZWi, the terminal humidity deviation value ZSi, the pH deviation value ZFi and the dust detection value ZKi are numerically calculated to obtain the terminal environment inspection value ZXi, wherein eq1, eq2, eq3 and eq4 are preset proportional coefficients, and the values ​​of eq1, eq2, eq3 and eq4 are all greater than zero; and the larger the value of the terminal environment inspection value ZXi, the greater the damage caused to the trusted terminal i by the environment in which it is located;

[0050] The terminal environment analysis value ZXi is numerically compared with the preset terminal environment analysis threshold. If the terminal environment analysis value ZXi exceeds the preset terminal environment analysis threshold, the trusted terminal i is judged to be in a terminal environment damage state. When the trusted terminal i is judged to be in a terminal environment damage state, corresponding warning information is generated and sent to the intelligent terminal of the corresponding trusted personnel via the communication management platform, so that the corresponding trusted personnel can timely grasp the information of the corresponding trusted terminal i being damaged by the environment, and perform environmental regulation in time as needed, so as to help improve the service life of the trusted terminal i and ensure its safe and stable operation, and can provide data support for the analysis process of the trusted terminal pre-evaluation module.

[0051] Embodiment 3: Figure 2 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that the communication management platform is connected to the trusted terminal pre-evaluation module in communication, the trusted terminal pre-evaluation module obtains all trusted terminals, and marks the corresponding trusted terminal as i; the production interval time and the total use time of the trusted terminal i are collected, wherein the production interval time is a data value indicating the interval time between the production date of the trusted terminal i and the current date, and the total use time is a data value indicating the use time of the trusted terminal i in the historical stage; the production interval time and the total use time are numerically compared with the corresponding preset production interval time threshold and the preset total use time threshold, respectively. If the production interval time or the total use time exceeds the corresponding preset threshold, it indicates that the equipment condition of the trusted terminal i is poor and tends to be scrapped, which is not conducive to ensuring the security of online audio and video transmission and the display effect, and then a high-risk use signal of the trusted terminal i is generated;

[0052] If the production interval and the total usage time do not exceed the corresponding preset thresholds, the preset production interval threshold is subtracted from the production interval to obtain the production interval time difference, and the preset total usage time threshold is subtracted from the total usage time to obtain the total usage time difference; and when the trusted terminal i is impacted by an external force, the maximum impact force, average impact force and duration of the impact of the corresponding external force impact process are collected, and the formula WXi=(a1 WDi+a2 WYi) / a3+a3 WSi numerically calculates the maximum impact force WDi, the average impact force WYi and the impact duration WSi to obtain the external force detection value WXi;

[0053] Among them, a1, a2, and a3 are preset proportional coefficients, and a3>a2>a1>0; and, the larger the value of the external force detection value WXi is, the greater the damage caused by the corresponding external force impact process to the trusted terminal i is; the external force detection value WXi is numerically compared with the preset external force detection threshold value, and if the external force detection value WXi exceeds the preset external force detection threshold value, it indicates that the corresponding external force impact process causes greater damage to the trusted terminal i, and the corresponding external force impact process is marked as an external force high-damage process;

[0054] The number of external force high-loss processes involved in the trusted terminal i in the historical stage is obtained and marked as the external force high-loss frequency, and the total time that the trusted terminal i is in the terminal ring loss state in the historical stage is obtained and marked as the terminal ring loss time inspection value; through the formula KXi=(b3 KYi+b4 KFi) / (b1 KSi+b2 KTi+1) The production interval time difference KSi, the total time difference value KTi, the external force high loss frequency KYi and the terminal ring loss time inspection value KFi are numerically calculated to obtain the trusted terminal traceability value KXi, where b1, b2, b3, and b4 are preset proportional coefficients, and the values ​​of b1, b2, b3, and b4 are all positive numbers;

[0055] Moreover, the larger the value of the trusted terminal traceability value KXi is, the worse the device condition of the trusted terminal i is, and the less conducive it is to ensuring the security of online audio and video transmission and display effects; the trusted terminal traceability value KXi is numerically compared with the preset trusted terminal traceability threshold. If the trusted terminal traceability value KXi exceeds the preset trusted terminal traceability threshold, it indicates that the device condition of the trusted terminal i is poor, which is not conducive to ensuring the security of online audio and video transmission and display effects, and a high-risk signal for the use of the trusted terminal i is generated.

[0056] Further, if the trusted terminal traceability value KXi does not exceed the preset trusted terminal traceability threshold, the terminal evaluation period is set, preferably, the terminal evaluation period is fifteen days; the number of times the trusted terminal i is attacked by the network and invaded by viruses during the terminal evaluation period is collected and marked as the terminal network loss frequency analysis value, and the duration of the impact of the trusted terminal i by the network attack and virus invasion during the terminal evaluation period is collected and marked as the terminal network loss time analysis value; it should be noted that the larger the values ​​of the terminal network loss frequency analysis value and the terminal network loss time analysis value, the greater the security risk of the trusted terminal i, and the more serious the use risk;

[0057] The terminal network loss frequency analysis value and the terminal network loss time analysis value are numerically compared with the preset terminal network loss frequency analysis threshold and the preset terminal network loss time analysis threshold, respectively. If the terminal network loss frequency analysis value or the terminal network loss time analysis value exceeds the corresponding preset threshold, it indicates that the security risk of the trusted terminal i is relatively large, and a high-risk signal for the use of the trusted terminal i is generated; if both the terminal network loss frequency analysis value and the terminal network loss time analysis value do not exceed the corresponding preset threshold, it indicates that the security risk of the trusted terminal i is relatively small, and a low-risk signal for the use of the trusted terminal i is generated;

[0058] And the high-risk usage signal or low-risk usage signal of the trusted terminal i is sent to the background supervision end through the communication management platform.
