Description

Technical Field

[0001] The present invention relates to the field of operation and maintenance management technology, and in particular to a link monitoring operation and maintenance method and system. Background Art

[0002] In order to effectively respond to changes in domestic and international security situations, more and more cameras are deployed in more and more scenarios, and the retention time of surveillance videos has gradually transitioned from the early 15 days to 90 days or even more than 180 days. Faced with the increasingly large amount of surveillance video data, the industry's traditional response is to expand existing storage. The core problem that traditional solutions have to face is that the cost of storage construction is too high, the required cabinet space is extremely large, and the electricity and hard disk maintenance fees in the subsequent operation process have skyrocketed. With the development and application of video compression technology, surveillance video compression equipment has been applied to the storage system of surveillance videos.

[0003] However, the application of surveillance video compression equipment will bring new problems, namely, increasing the transmission link of video stream data, thereby increasing the risk of link abnormality. Once the link is abnormal, it will lead to the loss of surveillance video, which may cause huge losses.

[0004] In addition, the current security monitoring system faces a significant challenge: the established monitoring equipment, transmission equipment, server equipment, etc. have a variety of brands. During the project operation and maintenance, the self-established operation and maintenance system has led to the emergence of operation and maintenance islands. With the continuous expansion and enrichment of the monitoring system, more and more equipment is integrated into it, which undoubtedly further aggravates the difficulty of global operation and maintenance control.

[0005] In order to meet this challenge, we urgently need to establish a unified operation and maintenance platform, integrate security terminals, storage, transmission, servers and central equipment, break down brand barriers, and realize centralized monitoring and management of cross-brand equipment, so as to optimize resource allocation and improve system operation and maintenance efficiency and overall control. Summary of the invention

[0006] Since the existing methods have the above-mentioned problems, an embodiment of the present invention proposes a link monitoring and operation method and system.

[0007] Specifically, the embodiment of the present invention provides the following technical solutions:

[0008] In a first aspect, an embodiment of the present invention provides a link monitoring and operation method, including:

[0009] The monitored network element is connected to the operation and maintenance center, which monitors the status of all links within the monitored range to determine whether there is an abnormality in at least one link. If not, the monitoring continues; if so, the link abnormality response strategy is activated and the execution of the abnormal response strategy is stopped until the abnormal link returns to normal.

[0010] The links include interval links established between the monitored network elements and monitoring links established between the monitored network elements and the operation and maintenance center.

[0011] The monitored network elements include: a video monitoring terminal, a monitoring video compression device, and a monitoring video storage device.

[0012] In a second aspect, an embodiment of the present invention provides a link monitoring and operation and maintenance system, including:

[0013] The link monitoring and operation and maintenance system comprises: a plurality of monitored network elements and an operation and maintenance center.

[0014] The multiple monitored network elements include: a video monitoring terminal, a monitoring video compression device, and a monitoring video storage device.

[0015] The operation and maintenance center includes:

[0016] An access module is used to access the multiple monitored network elements.

[0017] The monitoring module is used to monitor the status of all links within the monitoring range and determine whether there is an abnormality in at least one link.

[0018] The links include interval links established between the monitored network elements and monitoring links established between the monitored network elements and the operation and maintenance center.

[0019] The response module is used to start the link abnormality response strategy when at least one link is abnormal, and stop executing the abnormality response strategy until the abnormal link returns to normal.

[0027] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0028] Figure 1 A flow chart of a link monitoring and operation method provided by an embodiment of the present invention is shown as follows: Figure 1 As shown, the link monitoring operation and maintenance method provided by the embodiment of the present invention specifically includes the following contents:

[0029] Step 1: The monitored network element is connected to the operation and maintenance center, and the operation and maintenance center monitors the status of all links within the monitored range.

[0030] The monitored network elements include: a video monitoring terminal, a monitoring video compression device, and a monitoring video storage device.

[0031] The links include the interval links established between the monitored network elements and the monitoring links established between the monitored network elements and the operation and maintenance center, such as Figure 2 shown.

[0032] Specifically, the monitored network elements establish interval links through standard protocols, and the standard protocols include but are not limited to: 28181 protocol, SDK protocol, ONVIF protocol, RTSP protocol, and Websocket protocol.

[0033] In particular, since there are many manufacturers producing video surveillance terminals, in order to enable the operation and maintenance center to connect to various devices from different manufacturers, models, versions, and with widely varying capabilities, a monitoring link is established between the monitored network element and the operation and maintenance center through an agreed protocol.

[0034] It should be noted that the operation and maintenance center can be an operation and maintenance platform independent of other business platforms, or can be integrated into any business platform as a module. The deployment scheme of the operation and maintenance center is not limited in the embodiments of the present invention.

[0035] Step 2, determine whether at least one link is abnormal, if not, continue monitoring; if so, start the link abnormality response strategy, and stop executing the abnormal response strategy until the abnormal link returns to normal.

[0036] The determining whether at least one link is abnormal includes:

[0037] If the operation and maintenance center cannot obtain the operation and maintenance information of at least one interval link within the monitoring range, and / or the operation and maintenance center cannot establish a connection with at least one monitored network element, it is determined that at least one link is abnormal.

[0038] The operation and maintenance messages include, but are not limited to: service operation status, usage of memory, CPU, hard disk, network port, and business operation alarm events.

[0039] The starting link abnormality response strategy includes:

[0040] In one embodiment, if at least one link abnormality exists only in the inter-link, the takeover strategy is initiated.

[0041] The takeover strategy includes:

[0042] An end-to-end link with at least one section link abnormality is located and recorded as a target link.

[0043] The end-to-end link refers to a complete link from the video surveillance terminal to the surveillance video storage device.

[0044] If at least one section link in the end-to-end link is abnormal, the surveillance video recorded by the video surveillance terminal in the target link cannot be stored in the surveillance video storage device, resulting in video loss.

[0045] Disconnect other normal section links in the target link.

[0046] The operation and maintenance center sends the location information of the target video surveillance terminal to the surveillance video storage device, and at the same time sends an instruction to turn on the video storage switch of the surveillance video storage device, starts the active video storage function of the surveillance video storage device, and creates a video plan.

[0047] The target video surveillance terminal is a video surveillance terminal in the target link.

[0048] The monitoring video storage device establishes a connection with the target video monitoring terminal according to the received point information of the target video monitoring terminal, and directly stores the monitoring video in the monitoring video storage device.

[0049] In another embodiment, the alarm strategy is initiated only if at least one link abnormality exists in the monitored links.

[0050] The alarm strategy includes: reporting alarm events, starting log analysis, and performing troubleshooting.

[0051] The abnormality of the monitoring link does not affect the services of monitoring video streaming, compression, storage, etc. Therefore, the operation and maintenance center does not need to implement a takeover strategy.

[0052] In another embodiment, if at least one link abnormality exists in the interval link and at least one link abnormality exists in the monitoring link, the takeover strategy and the alarm strategy are simultaneously initiated.

[0053] The takeover strategy includes:

[0054] An end-to-end link with at least one section link abnormality is located and recorded as a target link.

[0055] The end-to-end link refers to a complete link from the video surveillance terminal to the surveillance video storage device.

[0056] If at least one section link in the end-to-end link is abnormal, the surveillance video recorded by the video surveillance terminal in the target link cannot be stored in the surveillance video storage device, resulting in video loss.

[0057] Disconnect other normal section links in the target link.

[0058] The operation and maintenance center sends the location information of the target video surveillance terminal to the surveillance video storage device, and at the same time sends an instruction to turn on the video storage switch of the surveillance video storage device, starts the active video storage function of the surveillance video storage device, and creates a video plan.

[0059] The target video surveillance terminal is a video surveillance terminal in the target link.

[0060] The monitoring video storage device establishes a connection with the target video monitoring terminal according to the received point information of the target video monitoring terminal, and directly stores the monitoring video in the monitoring video storage device.

[0061] The alarm strategy includes: reporting alarm events, starting log analysis, and performing troubleshooting.

[0062] In another embodiment, if both the link between the video surveillance terminal and the downstream network element and the link between the video surveillance terminal and the operation and maintenance center are abnormal, the video surveillance terminal is judged to be offline, the video surveillance is checked, and an attempt is made to reconnect.

[0063] When the abnormal link returns to normal, stopping executing the abnormal response strategy includes:

[0064] Stop executing the takeover strategy, including:

[0065] The section link with abnormality periodically attempts to connect and regularly reports the online message to the operation and maintenance center.

[0066] When the operation and maintenance center receives an online message of an abnormal network element, the operation and maintenance center sends an instruction to the monitoring video storage device to turn off the video storage switch of the monitoring video storage device, turns off the active video storage function of the monitoring video storage device, and re-establishes the end-to-end link from the video monitoring terminal to the monitoring video storage device.

[0067] Figure 3 A business process diagram is shown for starting the takeover strategy until the abnormal link returns to normal.

[0068] Stop executing alert policies, including:

[0069] The monitoring link with abnormality periodically attempts to connect and regularly reports the online message to the operation and maintenance center.

[0070] When the operation and maintenance center receives the online message of the abnormal network element, the operation and maintenance center stops reporting the alarm event, starts log recording, and stops troubleshooting.

[0071] Optionally, in another embodiment, before starting the link abnormality response strategy, a retry mechanism is executed, such as Figure 4 shown.

[0072] Configure the retry mechanism strategy and set the retry strategy parameters, which may include one or more of the following: retry time interval, number of retries, and total retry time.

[0073] It is understandable that, in the embodiment of the present invention, there is no restriction on the specific parameter values ​​of the retry strategy, which can be specifically set according to the actual application scenario.

[0074] If the operation and maintenance center still cannot obtain the operation and maintenance information of at least one interval link within the monitoring range after executing the retry mechanism, and / or the operation and maintenance center cannot establish a connection with at least one of the monitored network elements, it is determined that there is at least one link abnormality.
