[0027] It should be noted that the substation network message recording and analysis device is mainly used in smart substations to monitor, capture, analyze, store and count various network messages in the entire station in real time.

[0028] Before step 100, it is necessary to construct a data set and an operation set of a multi-process shared data model: that is, according to the data operation requirements of the substation network message recording and analysis device for each business, define the data set and operation set of the data sharing data model. Specifically, it includes: Step S110: define a shared data model between various business processes in the substation network message recording and analysis device, and define necessary information contained in each of the multiple shared data items in the shared data model.

[0029] Step S120: Determine an operation mode set for each shared data item in the multiple shared data items.

[0030] It should be noted that the operation mode set includes: a hash table hash, an ordered set zset and an unordered set set.

[0031] After step S120, the method further includes: In a case where it is determined that the operation mode set of the shared data item is a hash table hash access mode based on a first key attribute value, a hash storage index is allocated to the shared data item based on the first key attribute value; In the case where it is determined that the operation mode set of the shared data item is an ordered set zset access mode based on a second key attribute value, a sorted storage index is allocated to the shared data item based on the second key attribute value; When it is determined that the operation mode set of the shared data item is an unordered set set access mode and hash table hash access or ordered set zset access is not required, a hash storage index and a sorted storage index are not established.

[0032] Step S130: Inheriting the management interface of the shared memory block in the operation mode set of each shared data item; wherein the management interface includes: operation commands for creating, destroying, initializing, accessing and backing up the shared memory block.

[0033] In one embodiment, the above steps are described in detail.

[0034] 1) Define the shared data model between each business process of the substation network message recording and analysis device. The shared data model specifically includes: equipment management information, business process status information, message cache information, alarm information, self-test information, data analysis results, network message data, etc.

[0035] 2) Define the necessary information that each data item needs to contain in the shared data model, including the unique name of the shared data item, the maximum number of entries in the shared data, and the maximum capacity of a single shared data item.

[0036] 3) Count the set of operations required for each multi-process shared data, including hash table, ordered set zset and unordered set set.

[0037] 4) If the shared data needs to include a hash access method based on the key attribute value, a hash storage index is allocated based on the key attribute value.

[0038] 5) If a multi-process shared data needs to include an ordered set access method based on a key attribute value, a sorted storage index is allocated based on the key attribute value.

[0039] 6) If a multi-process shared data needs to include unordered set access methods and does not require hash or ordered set access, then hash index and sorted storage index are not created.

[0040] 7) In each multi-process shared data operation set, the shared memory block management interface is inherited: managed_shared_memory.

[0041] 8) The managed_shared_memory in step 7) contains five operation commands: creation, destruction, initialization, opening (access), and backup of shared memory blocks.

[0042] Step 200: allocate a corresponding shared memory block to each of the multiple shared data items according to the data structure of the shared data model, and set the shared memory block in a preset manner.

[0043] Specifically, step 200 includes: Step 210: Acquire the multiple shared data items and necessary information contained in each of the multiple shared data items.

[0044] Step 220: Allocate a corresponding shared memory block to each of the multiple shared data items through the management interface of the shared memory block.

[0045] Step 230: Set an access tag and a maximum storage capacity for each shared memory block respectively, and initialize each shared memory block through the management interface of the shared memory block.

[0046] In one embodiment, the above steps are described in detail.

[0047] 1) Obtain basic information of all multi-process shared data items, including the shared data item list described in the above embodiment and necessary information of each shared data item.

[0048] 2) Create a shared memory block for each multi-process shared data item through managed_shared_memory in the above embodiment.

[0049] 3) Shared memory block access label setting: Set a unique name for the shared data item for each shared memory block.

[0050] 4) Setting the maximum storage capacity of a shared memory block: The maximum storage capacity of each shared memory block is determined by the product of the maximum number of entries required to be stored and the maximum storage capacity required to store each entry.

[0051] 5) Shared memory block initialization: Set the initial value of each shared memory block to 0 through managed_shared_memory.

[0052] Step 300, determine the access rights and waiting mode of each shared memory block according to the read and write requirements of different businesses for shared data, and determine the retention period and storage capacity of the data in each shared memory block according to the setting method of the shared memory block; wherein the access rights and waiting mode are used to: limit and manage the access of multiple processes to the shared memory block, and the retention period and storage capacity are used to: manage the storage time and storage capacity of the data in the shared memory block.

[0053] Specifically, in step 300, the access rights and waiting modes of each shared memory block are determined according to the read and write requirements of different services for shared data, including: Step 310: Determine the unique number corresponding to each shared memory block according to a preset order.

[0054] Step 320: When the shared memory block provided by the management interface is accessed, encapsulate and generate an access interface based on the unique number of the shared memory block.

[0055] Step 330: Set an access permission code and a waiting mode on the uniquely numbered access interface of the shared memory block; wherein the permission code includes: write permission and read permission, and the waiting mode includes: blocking mode and non-blocking mode.

[0056] In one embodiment, the above steps are described in detail.

[0057] 1) Number all shared memory blocks in sequence.

[0058] 2) Bind the number to the corresponding shared memory block.

[0059] 3) Based on the shared memory block opening (access) provided by managed_shared_memory, an opening (access) interface operator_shared_memory based on the memory block number is encapsulated.

[0060] 4) Furthermore, an access permission code is added to the access interface operator_shared_memory. The permission code can be divided into write permission (WO) and read permission (RO).

[0061] 5) Furthermore, a waiting mode for access is added to the access interface operator_shared_memory. The waiting mode can be divided into blocking mode and non-blocking mode.

[0062] 6) Further, if the shared memory block needs to be accessed with read permission, operator_shared_memory will determine whether the write permission of the shared memory block is activated and whether there is a request for write permission.

[0063] 7) Further, if the write permission is not activated or there is no write permission request, the read permission is directly activated, and data is read after activation, and the read permission is released after the reading is completed; if the write permission is activated or there is a write permission request, the read operation mode is further determined.

[0064] 8) Further, if the read waiting mode is a non-blocking mode, the resource occupancy is returned; if the read mode is a blocking mode, the process waits until there is no write permission request and the write permission is released, and then returns to step 8) to continue execution.

[0065] 9) If the shared memory block needs to be accessed with write permission, operator_shared_memory will determine whether the shared memory block has write permission activated or read permission activated.

[0066] 10) Further, if the write permission is not activated and the read permission is not activated, the write permission is directly activated, data is written after activation, and the write permission is released after the writing is completed; if the write permission is activated or the read permission is activated, the read operation mode is further determined.

[0067] 11) Furthermore, if the waiting mode for writing is non-blocking mode, the resource occupancy is returned; if the reading mode is blocking mode, write permission is requested and waits until the write permission is released, data is written, and the write permission is released after the writing is completed.

[0068] Specifically, after respectively determining the retention period and storage capacity of the data in each shared memory block according to the setting mode of the shared memory block in step 300, the method further includes: Step 410: Obtain the dump location of the target shared memory block, and clear the data content of the dump location.

[0069] Step 420, compress the real-time data of the target shared memory block through the management interface, back up the compressed data to the dump location, and record the data change instructions through the access interface; wherein the data change instructions include: adding, modifying and deleting data in the shared memory block.

[0070] Step 430: Obtain the backup start time and remaining dump capacity of the dump location.

[0071] Step 440: When the difference between the current time and the backup start time is greater than the retention period, and / or the remaining dump capacity is less than a preset capacity, stop recording data change instructions through the access interface; wherein the preset capacity is determined based on the storage capacity.

[0072] In one embodiment, the above steps are described in detail.

[0073] 1) Set the configuration parameters for data dump, including the shared memory block number to be dumped, the dump location, the maximum dump period (i.e. the retention period mentioned above), and the maximum dump capacity (i.e. the storage capacity mentioned above).

[0074] 2) Empty everything already in the dump location.

[0075] 3) Further, it is determined through the read interface of operator_shared_memory whether the shared memory block has been created. If not, it is created and initialized according to the above embodiment.

[0076] 4) All real-time data of the specified shared memory block is compressed through managed_shared_memory, and the backup value dump location is backed up, and the backup start time is registered at the dump location.

[0077] 5) Furthermore, in operator_shared_memory, a data recording function is enabled for instructions involving data changes (including the addition, modification, and deletion of all or part of the data in the shared memory block).

[0078] 6) When operator_shared_memory receives a data change instruction, the data recording function stores the data change time, change source (reason), change range, and the changed content in the transfer storage location.

[0079] 7) Furthermore, when the remaining capacity for dumping is insufficient, the difference between the current time and the backup start time is greater than the longest period, or the recorder actively stops data recording, the data recording function is turned off.

[0080] The data storage and management method for the substation network message recording and analysis device provided by the embodiment of the present invention constructs a shared data model between business processes by decomposing the business relationship of the substation network message recording and analysis device, and instantiates relevant data elements in the shared memory; at the same time, the shared memory block is encapsulated through the read and write operations of the shared memory block to form an operation set of the business layer on the shared memory block, and on this basis, the shared memory block historical data is recorded by incremental storage.
