The method for processing cascade exception recovery of the video monitoring management platform in the embodiment comprises the following steps:
when a cascade lower platform adds an organization, virtual equipment of the organization is created, wherein the virtual equipment at least comprises virtual equipment name information and address information used for representing the states of all equipment of the organization;
the cascade lower platform pushes shared resources to the upper platform, and the shared resources comprise organization information, all physical equipment information and virtual equipment information under the organization;

comparing the retrieval result with the organization and the virtual equipment before the abnormality, and judging whether the equipment information under the organization is changed;
if the virtual equipment is changed, the superior platform searches the equipment resources of the organization where the virtual equipment corresponding to the change is located, and completes equipment information synchronization.
In this embodiment, when the device resources pushed to the upper platform by the lower platform reach one hundred thousand or more, the data synchronization efficiency between the upper and lower platforms can be greatly improved, the data synchronization time after the upper and lower platforms are reconnected is reduced, and the scene customer experience is improved.
In this embodiment, when a lower platform is cascaded to a higher platform to push shared resources for the first time, a virtual Device0 is created for each organization of the shared resources, the virtual Device does not participate in the actual service of the security monitoring platform, and only serves as an information digest storage object of each shared resource organization, and is pushed to the higher platform together, the higher platform receives the virtual Device0 of each shared organization and stores the same with the common Device in the same manner, and the digest of the virtual Device in this embodiment is an MD5 digest.
In this embodiment, the cascade lower platform pushes the abstract of the virtual device as the shared resource to the upper platform together with all the shared resources, and converts the abstract into a virtual device name used for representing device resource information, where the device resource information includes a virtual device system code, a device name, a device manufacturer, a device type, a device state, a device address, and a device location. After the cascade abnormal scene is reconnected, each shared resource organization of the lower platform only needs to recalculate the abstract of the shared Device under the organization and give the abstract to the Device0 of the organization, and pushes the Device0 Device information to the upper platform for abstract comparison, so that whether the Device information under the corresponding shared organization changes can be determined, the aim of synchronizing all the Device information under the organization to the upper platform through the retrieval message of one Device is achieved, the synchronization speed of the cascade abnormal scene Device is greatly improved, and the service recovery time is reduced.
In this embodiment, the most important attribute fields of the virtual Device0 are: the virtual device system code includes a device id (deviceid), a device Name (Name), an affiliated platform device (Owner), a CivilCode (CivilCode), and an Address (Address). The virtual device system code includes a center code, an industry code, a type code and a serial number, optionally, the generation rule is generated according to the requirement of GB/T28181-. Wherein, the type code (3 bits) is a virtual device, and the type code of the GB/T28181-2016 protocol does not define the type of the virtual device, and this embodiment adopts 600 in the protocol extension type code segment as the type code of the virtual device, taking the "north yu district" as an example, and the other field codes are as shown in fig. 1.
In this embodiment, the Device Name (Name) of the virtual Device is generated by using Device0 as the prefix of the Device Name, optionally, "_" as a separator, and calculating a 128-bit MD5 digest character string as a Name value after the separator with other shared Device resource information (Device ID, Device Name, Device manufacturer, Device type, Device status, Device address, Device longitude, Device latitude, etc.) of the shared organization where the virtual Device is located. In this embodiment, the device field (Owner) of the belonging platform is the same as the generation rule of the general device in the organization, i.e. the national standard code ID of the platform where the virtual device is located. The information of the organization code (CivilCode) is the same as the generation rule of the ordinary device in the organization, i.e. the ID of the organization in which the virtual device is located.
In this embodiment, the Address information at least includes the number of devices in the organization to which the virtual Device belongs and the Device status, and since the virtual Device does not correspond to an actual geographic location, this field is used in this embodiment to store the on/off-line status of all real devices in the organization in which the virtual Device0 is located; optionally, the specific method is that the Address is an decimal character string + "_" + device status code of the number of real devices under the organization, and the device status code records the on/off status of the real device under the shared organization. Sorting the DeviceIDs of all shared devices in the shared organization from small to large, checking the state of each device, if the device is online, the state is 1, and if the device is offline, the state is 0, and forming a device state code character string by the states of all the devices according to the sequence.
In this embodiment, in the first data synchronization stage of the virtual devices in the shared organization, when the upper and lower platforms create a cascade relationship, the lower platform pushes the virtual Device0 in each shared organization to the upper platform in the same way as the normal Device, the upper platform saves the data of the virtual Device in the same way as the normal Device, but the virtual Device0 does not support other services, and when the cascade relationship is normal, and information or status of the Device to which the shared organization belongs is updated, the upper and lower platforms need to synchronously update the Device name of the virtual Device0 and the corresponding field value of the address recording the status distribution of the Device in the organization. After the cascade connection is abnormally interrupted, the information of the Device0 on the upper platform is kept consistent with that before the interruption, and for the common shared Device, after the cascade connection is interrupted, the information of the Device is not changed, and the Device state is set to be offline, but for the virtual Device, the information is still kept consistent with that before the interruption, so that the comparison is carried out when the cascade connection state is recovered. After the cascade connection relationship is restored again, the superior platform only needs to retrieve the information of the organization shared by the subordinate platform and the virtual machine Device0 of each organization, compares the received information of the virtual Device0 with the state code and the historical data, and can judge whether the shared information of the organization is changed, if the Device information and the Device state code are not changed, the Device state pushed by cascade connection can be set to be on-line or off-line directly according to the state code, if the abstracts of the virtual Device devices 0 of some organizations are inconsistent, only the Device corresponding to the organization needs to be retrieved, and all the organized devices do not need to be retrieved. If the abstracts of the virtual devices 0 of some organizations are consistent, only the corresponding state codes of the address fields are different, the Device states are set according to the corresponding state codes, so that the data synchronization time among the cascading platforms is greatly reduced, and the data synchronization efficiency is improved.
As shown in fig. 2, the following further explains the processing flow before and after the exception recovery of the cascade relation of the upper and lower platforms by a specific embodiment:
s101, when an organization is added, the cascade subordinate platform automatically creates a virtual Device0 of the organization, and maintains an abstract of a virtual Device name MD5 and an Address field for recording states of all devices of the organization;

s108, after a period of time, the upper and lower level connections are recovered to be normal;
s109, the lower platform cascade service is registered to the upper platform again, and the upper platform issues a resource subscription to the lower platform cascade service;
s110, the superior platform searches all corresponding virtual devices when checking the organization virtual devices before cascade abnormity;
s111, the superior platform carries out abstract comparison on the virtual Device name MD5 of the corresponding result retrieved by the virtual Device0 of each organization, if the MD5 abstracts are consistent, the Device of the inferior platform under the shared organization has no information change, and the step S112 is executed, otherwise, the Device under the organization has the information change execution step S113;
