Description

Technical Field

[0001] The present invention relates to the field of communication security technology, and in particular to a method and system for distributing and supervising emergency management information based on network security. Background Art

[0002] The construction of transportation construction projects such as construction sites often takes a long time, so there are often resident personnel stationed at the construction sites of these projects for a long time. Since these construction sites are often located in relatively dangerous mountainous areas, some critical situations are prone to occur. Therefore, in order to supervise the safety of the resident personnel, the emergency information distribution emergency message distribution management center needs to promptly distribute the emergency information issued by the emergency message distribution management center to the resident person in charge. The resident person in charge evacuates the resident personnel in time and reports the number of evacuees to the superiors. The emergency message distribution management center receives the feedback from the layers and believes that the resident personnel have been safely evacuated. However, in an emergency, the resident personnel cannot accurately grasp the actual number of people in the resident, and may directly report the number of people who punch in. In this way, it is easy for the actual number of people who need to be evacuated in the resident to be greater than the number of evacuees reported by the resident person in charge, resulting in the management department being unable to timely supervise whether the resident person in charge actually implements the emergency information. Summary of the invention

[0003] The purpose of the present invention is to provide a method for supervising the distribution of emergency management information based on network security, which counts the actual number of people evacuated through monitoring videos, and requires network security verification when calling monitoring videos to successfully call and avoid leakage of resident video data. And by verifying the number of people through video, it is possible to effectively supervise whether the person in charge of the resident actually implements the notification information.

[0004] In order to achieve the above objectives, this application adopts the following scheme:

[0005] On the one hand, the present application provides a method for supervising the distribution of emergency management information based on network security, and the emergency message distribution management center performs the following steps:

[0006] S1, sending emergency notification information to the terminal of the resident person in charge, and recording the receiving time t1 fed back when the terminal of the resident person in charge receives the emergency notification information;

[0007] S2, receiving the number of people reported to be evacuated from the terminal of the person in charge of the resident, and recording the reporting time t2 of the terminal of the person in charge of the resident at this time;

[0008] S3. When receiving the number of evacuees reported by the resident person in charge terminal, a video call request is sent to the video network security monitoring center of the resident where the resident person in charge terminal is located, and security verification is performed in combination with the resident person in charge terminal and the video network security monitoring center;

[0009] S4. When the security verification is passed, the video data at the entrance of the resident safety area during the time period t1-t2 is called from the video network security monitoring center to count the number of people entering the safety area and obtain the actual number of people evacuated;

[0010] S5. Compare the actual number of evacuees with the reported number of evacuees, and supervise whether the on-site person in charge actually implements the emergency notification information based on the comparison result.

[0011] In some specific embodiments, the security verification process includes:

[0012] S41. After receiving the video call request, the video network security monitoring center triggers the video network security monitoring center to perform identity and authority verification with the terminal of the person in charge of the station where the video network security monitoring center is located;

[0013] S42. When the identity authority verification is passed, the video network security monitoring center analyzes the video call request and obtains the video time period and monitoring device requested for call;

[0014] S43. The video network security monitoring center intercepts the video data within the requested video time period from the monitoring video stream of the corresponding monitoring device according to the requested video time period and the monitoring device, and waits for the emergency message distribution management center to call it.

[0015] In some specific implementation schemes, the process of identity and authority verification in step S41 is as follows:

[0016] The video network security monitoring center sends verification information to the resident person in charge terminal and receives identity verification information and request verification information returned by the resident person in charge terminal;

[0017] The identity verification information is authenticated with the identity authentication information stored in the video network security monitoring center. When the identity authentication is passed, the port transmission flow control amount for data transmission between the video network security monitoring center and the emergency message distribution management center is set according to the request verification information.

[0018] In some specific implementation schemes, the request verification information includes the receiving time recorded when the resident person in charge terminal receives the emergency notification information and the reporting time recorded when the emergency message distribution management center is fed back, then the port transmission flow control amount is set to:

[0019] The video network security monitoring center queries the monitoring equipment corresponding to the resident security area, estimates the size of the video to be verified that needs to be intercepted according to the video bit rate of the monitoring equipment based on the receiving time and the reporting time; and sets the size of the video to be verified as the port transmission flow control amount.

[0020] In some specific implementation schemes, step S4 also includes a flow control process, the specific process is:

[0021] The size of the video data to be transmitted within the requested video time period is calculated based on the video bit rate of the monitoring device. When the size of the video data to be transmitted is within the port transmission flow control range, the video data within the requested video time period is packaged and sent to the emergency message distribution management center.

[0022] In some specific implementation schemes, starting from the receiving time t1, the reminder information is sent to the terminal of the resident person in charge at regular intervals until the feedback from the terminal of the resident person in charge is received.

[0023] In some specific embodiments, the process of step S5 is:

[0024] When the actual number of evacuees is not equal to the reported number of evacuees, an error reporting reminder is sent to the terminal of the person in charge of the resident, reminding the person in charge of the resident to re-count the resident personnel and re-report the number of evacuees to the emergency message distribution management center. Only the first reporting time is updated, and steps S2-S5 are repeated until the actual number of evacuees is equal to the reported number of evacuees.

[0025] In some specific embodiments, the steps are further included:

[0026] Obtain the number of resident personnel corresponding to the resident terminal where the resident person in charge who reported the number of evacuees is located;

[0027] When the actual number of evacuees, the number of resident personnel and the reported number of evacuees are not equal, an error reporting reminder is sent to the resident person in charge terminal to remind the resident person in charge to re-count the resident personnel and re-report the number of evacuees to the emergency message distribution management center.

[0028] In some specific implementation plans, if the reported number of evacuees is equal to the number of resident personnel and greater than the actual number of evacuees, an incomplete evacuation reminder is sent to the resident person in charge terminal to remind the resident person in charge to continue evacuating the resident personnel and re-report the number of evacuees to the emergency message distribution management center.

[0029] In the second aspect, the present application provides an emergency management information distribution and supervision system based on network security, including: a resident person in charge terminal, a video network security monitoring center, and an emergency message distribution management center. The video network security monitoring center is equipped with an authority server, wherein:

[0030] The emergency message distribution management center is used to send emergency notification information to the terminal of the resident person in charge, and record the receiving time t1 fed back when the terminal of the resident person in charge receives the emergency notification information;

[0031] Receive the number of people evacuated reported by the terminal of the person in charge of the resident, and record the reporting time t2 of the terminal of the person in charge of the resident at this time;

[0032] Upon receiving the number of evacuees reported by the resident person in charge terminal, a video call request is sent to the video network security monitoring center of the resident where the resident person in charge terminal is located;

[0033] The video data at the entrance of the resident safety area during the time period t1-t2 is called from the video network security monitoring center to count the number of people entering the safety area and obtain the actual number of people evacuated;

[0034] Compare the actual number of evacuees with the reported number of evacuees, and supervise whether the person in charge of the evacuation has truly implemented the emergency notification information based on the comparison results;

[0035] The authority server is used to perform security verification with the emergency message distribution management center and the resident person in charge terminal according to the video call request. When the security verification is passed, the video data at the entrance of the resident security area in the time period t1-t2 is called.

[0036] The present invention has the beneficial effects:

[0037] By calling the surveillance video within the emergency feedback time period, the feedback time period is the time between the moment when the person in charge's terminal receives the emergency notification message and the moment when the evacuation information is reported to the management, the video call request is triggered when the evacuation information reported by the person in charge's terminal is received. In order to avoid leakage of video information, security verification is required with the video network security monitoring center during the call. When the security verification is passed, only the video data at the entrance of the resident safety area within the feedback time period is allowed to be called from the video network security monitoring center. The number of people entering the safety area is counted to obtain the actual number of evacuees. By comparing it with the number of evacuees reported by the person in charge's terminal, it is possible to supervise whether the resident person in charge actually implements the emergency notification information, and ensure the safety of the information transmission process.

[0047] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0048] Example 1

[0049] like Figure 1 As shown, on the one hand, the present invention provides a method for supervising the distribution of emergency management information based on network security, and the emergency message distribution management center performs the following steps:

[0050] S1, sending emergency notification information to the terminal of the resident person in charge, and recording the receiving time t1 fed back when the terminal of the resident person in charge receives the emergency notification information;

[0051] In order to ensure that the responsible person's terminal does not receive the emergency management notification information in time, starting from the receiving time t1, the reminder information is regularly sent to the resident responsible person's terminal until the feedback from the resident responsible person's terminal is received;

[0052] S2, receiving the number of people reported to be evacuated from the terminal of the person in charge of the resident, and recording the reporting time t2 of the terminal of the person in charge of the resident at this time;

[0053] S3. When receiving the number of evacuees reported by the resident person in charge terminal, a video call request is sent to the video network security monitoring center of the resident where the resident person in charge terminal is located, and security verification is performed in combination with the resident person in charge terminal and the video network security monitoring center;

[0054] S4. When the security verification is passed, the video data at the entrance of the resident safety area during the time period t1-t2 is called from the video network security monitoring center to count the number of people entering the safety area and obtain the actual number of people evacuated;

[0055] The security verification process in this application includes identity verification and flow control, such as Figure 4 As shown, specifically:

[0056] S41. After receiving the video call request, the video network security monitoring center triggers the video network security monitoring center to perform identity and authority verification with the terminal of the person in charge of the station where the video network security monitoring center is located;

[0057] Specifically, the video network security monitoring center sends verification information to the resident person in charge terminal and receives identity verification information and request verification information returned by the resident person in charge terminal;

[0058] The identity verification information is authenticated with the identity authentication information stored in the video network security monitoring center. When the identity authentication is passed, the port transmission flow control amount for data transmission between the video network security monitoring center and the emergency message distribution management center is set according to the request verification information.

[0059] The request verification information includes the receiving time recorded when the resident person in charge terminal receives the emergency notification information and the reporting time recorded when the emergency message distribution management center is fed back. The port transmission flow control amount is set to:

[0060] The video network security monitoring center queries the monitoring equipment corresponding to the resident security area, estimates the size of the video to be verified that needs to be intercepted according to the video bit rate of the monitoring equipment based on the receiving time and the reporting time; and sets the size of the video to be verified as the port transmission flow control amount.

[0061] S42. When the identity authority verification is passed, the video network security monitoring center analyzes the video call request and obtains the video time period and monitoring device requested for call;

[0062] S43. The video network security monitoring center intercepts the video data within the requested video time period from the monitoring video stream of the corresponding monitoring device according to the requested video time period and the monitoring device, and waits for the emergency message distribution management center to call it.

[0063] The size of the video data to be transmitted within the requested video time period is calculated based on the video bit rate of the monitoring device. When the size of the video data to be transmitted is within the port transmission flow control range, the video data within the requested video time period is packaged and sent to the emergency message distribution management center.

[0064] Generally speaking, the video time period requested by the emergency message distribution management center is equal to the time period between the receiving time t1 and the reporting time t2 in the request verification information sent by the resident person in charge terminal. Since the resident person in charge terminal and the video network security monitoring center are in the same local area network, the communication is more reliable, and the emergency message distribution management center and the resident are remote communications, which will inevitably pass through the public network. Therefore, it is easy to be attacked when requesting a call. Therefore, the information of the resident person in charge terminal and the information requested for the call can be used for two-way verification to avoid the situation where the time period of the requested call is not equal to the time period between the receiving time and the reporting time.

[0065] S5. Compare the actual number of evacuees with the reported number of evacuees, and supervise whether the on-site person in charge actually implements the emergency notification information based on the comparison result.

[0066] In order to prevent the person in charge from making false reports or inaccurately reporting the number of people due to the chaos on site, the actual number of evacuees is compared with the reported number of evacuees, and the evacuated personnel are verified again to avoid false reports by the person in charge of the station. Therefore, when the actual number of evacuees is not equal to the reported number of evacuees, an error reporting reminder is sent to the terminal of the person in charge of the station, reminding the person in charge of the station to re-count the resident personnel and re-report the number of evacuees to the emergency message distribution management center, and only update the first reporting time, and repeat steps S2-S5 until the actual number of evacuees is equal to the reported number of evacuees.

[0067] Since the emergency message distribution management center will pre-store the punch-in information of the resident personnel in the resident, in general, the number of resident personnel obtained through the punch-in device, the number of reported evacuees reported by the resident person in charge terminal, and the actual number of evacuees should be equal. If there is an inequality, there are many situations, such as: the resident person in charge did not accurately report the resident personnel, the resident person in charge lied about the number of evacuees, the resident personnel were not completely evacuated, etc. If only the actual number of evacuees is compared with the reported number of evacuees, it is impossible to accurately know the actual number of people who need to be evacuated in the resident. Therefore, the number of resident personnel can be combined to help determine whether the resident person in charge has completely evacuated the resident personnel. Specifically:

[0068] Obtain the number of resident personnel corresponding to the resident terminal where the resident person in charge who reported the number of evacuees is located;

[0069] When the actual number of evacuees, the number of resident personnel and the reported number of evacuees are not equal, an error reporting reminder is sent to the resident person in charge terminal to remind the resident person in charge to re-count the resident personnel and re-report the number of evacuees to the emergency message distribution management center.

[0070] Specifically, if the reported number of evacuees is equal to the number of resident personnel and greater than the actual number of evacuees, an incomplete evacuation reminder is sent to the resident person in charge's terminal, reminding the resident person in charge to continue evacuating the resident personnel and report the number of evacuees to the emergency message distribution management center again. At this time, it is very likely that the number of people reported directly by the resident person in charge based on the clock-in information is not the actual number of evacuees.

[0071] When the actual number of evacuees is equal to the number of resident personnel and greater than the reported number of evacuees, a reporting error reminder is sent to the resident person in charge terminal, reminding the resident person in charge to re-count the resident personnel and re-report the number of evacuees to the emergency message distribution management center. At this time, it is very likely that the resident person in charge did not correctly count the number of evacuees in the chaotic situation, and the resident person in charge can be reminded to re-count the number of people and report it.

[0072] There are also some more extreme situations. If the actual number of evacuees is equal to the reported number of evacuees and is greater than the number of stationed personnel, there may be people in the station who are not counted in the emergency message distribution management center's clocking-in system. At this time, the number of stationed personnel in the emergency message distribution management center can be corrected.

[0073] For example, in Figure 3In the scenario shown, the station and the safe area are in different locations. When the person in charge of the station receives the emergency notification information, he needs to evacuate the residents in the station to the safe area. At this time, the clock-in device installed at the entrance to the station is in the normally open state and cannot actively count the number of evacuees. Therefore, in order to avoid omissions when the person in charge actively evacuates the residents, the number of residents entering the safe area is counted through the monitoring equipment in the safe area. Specifically, when the emergency message distribution management center (hereinafter referred to as the management center) reaches the active person in charge terminal through layers of distribution, the resident person in charge terminal will pop up a message reception reminder to the resident person in charge. When the resident person in charge receives the emergency management notification information, he will click on "Received", record the receiving time t1 at this time, and feedback to the emergency message distribution management center. When the resident person in charge receives the notification from the emergency message distribution management center, he should respond in time to evacuate the resident personnel, evacuate the resident personnel to a safe area, and count the number of evacuees, and then fill in the evacuation information including the number of evacuees, resident location, resident name, resident safe area location, etc. in the message reporting interface. During this period, the emergency message distribution management center will also regularly send reminders to the resident person in charge terminal. Wake up until the resident person in charge clicks on the terminal to confirm the report, and records the reporting time t2 at this time. At this time, t1 and t2 will be reported to the emergency message distribution management center together with the evacuation information. When the emergency message distribution management center receives the evacuation information, it will automatically trigger a video call request to the video network security monitoring center of the current station. The video call request generally includes the time period of the request call and the name of the monitoring device to be called. The name of the monitoring device corresponds to the location of the monitoring device. Here, since the monitoring equipment of each station is generally named according to its installation location when it is installed, for example, the station gate, xx area, etc., then the general evacuation will be concentrated in a certain safe area. At this time, the monitoring equipment at the entrance of the safe area can be obtained according to the name of the safe area. In order to avoid video leakage from the video network security monitoring center, security verification is required when requesting a call. Here, in order to verify the identity of the resident person in charge, the linkage resident person in charge can also confirm whether the resident person in charge actually executes the notification information. Security verification includes identity authentication and flow control. When authenticating with the resident person in charge, the resident person in charge's terminal will feed back the recorded receiving time and reporting time to the monitoring video center. At this time, for the network security of its own data, the monitoring video center will estimate the data packet size out of the port, that is, the data transmission flow, based on the receiving time and reporting time fed back from the resident person in charge, and then compare it with the data size of the time period in the request sent from the emergency message distribution management center. On the one hand, it can verify that the request of the emergency message distribution management center is safe, and on the other hand, it can control the data transmission flow of the port to avoid unnecessary data leakage.

[0074] Example 2

The video network security monitoring center is equipped with an authority server, wherein:

[0076] The emergency message distribution management center is used to send emergency notification information to the terminal of the resident person in charge, and record the receiving time t1 fed back when the terminal of the resident person in charge receives the emergency notification information;

[0077] Receive the number of people evacuated reported by the terminal of the person in charge of the resident, and record the reporting time t2 of the terminal of the person in charge of the resident at this time;

[0078] Upon receiving the number of evacuees reported by the resident person-in-charge terminal, a video call request is sent to the video network security monitoring center of the resident where the resident person-in-charge terminal is located;

[0079] The video data at the entrance of the resident safety area during the time period t1-t2 is called from the video network security monitoring center to count the number of people entering the safety area and obtain the actual number of people evacuated;

[0080] Compare the actual number of evacuees with the reported number of evacuees, and monitor whether the person in charge of the evacuation has truly implemented the emergency notification information based on the comparison results;

[0081] The authority server is used to perform security verification with the emergency message distribution management center and the resident person in charge terminal according to the video call request. When the security verification is passed, the video data at the entrance of the resident security area in the time period t1-t2 is called.
