Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined or explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not construed as indicating or implying relative importance.
Referring to fig. 1, the present application provides a method for hierarchical processing of energy storage system information, including:
s10, receiving an access request of a user and generating a user access token, wherein the access request is used for inquiring energy storage system information of a target object; the energy storage system information of the target object comprises hierarchy information of the target object and complete information of the target object, and the user access token comprises identification information of an energy storage system to which the target object belongs; the energy storage system comprises a top object and a sub-object arranged below the top object, and the target object is the top object or the sub-object in the energy storage system.
In this step, the user access token includes identification information of the top-level object to which the target object belongs, such as an ID code, a sequence code, and the like, which can uniquely identify the top-level object information to which the target object belongs. In a specific application scenario, when a user needs to query specific information of the target object a, the user logs in/accesses the server. After the user logs in and accesses successfully, the server generates Token (Token means that Token is a Token in computer identity authentication), and the Token stores the ID code of the top-level object to which the target object a belongs. The ID code of the top-level object to which the target object A belongs does not change, and the ID code of the top-level object is directly acquired from the token when the target object A is accessed next time. When a user (possibly a target object in a certain query process) logs in, the ID of the top-level object to which the user belongs is recorded, all the following operations related to the user are related to the sub-level object under the top-level object, and the sub-level objects under other top-level objects cannot be operated.
In one embodiment, the energy storage system is any one of an energy storage structure system, an energy storage state system and an energy storage dealer system. The energy storage structure system can specifically comprise a top level object-battery stack, a secondary level object battery cluster and a tertiary level object battery monomer/battery core. The energy storage state system may specifically include different levels of voltage, current, power, state of charge, temperature, etc. in the energy storage structural system. The energy storage dealer system can specifically comprise a top-level dealer, a second-level dealer, a third-level dealer, a fourth-level dealer and a fifth-level dealer. For example, the energy storage system information is data information of an energy storage structure system, and includes hierarchical information and complete information of a plurality of energy storage structures. For example, the energy storage system information is data information of an energy storage state system, and includes hierarchical information and complete information of a plurality of energy storage states. For another example, the energy storage system information is data information of an energy storage dealer system, and includes hierarchical information and complete information of a plurality of energy storage dealers. More specifically, the target may be a cell 5 in the energy storage structure, the target may be a state of charge of a cell 8 in the energy storage state, and the target may be an energy storage dealer F.
And S20, judging whether the energy storage system information of the target object belongs to thermal data, wherein the thermal data is a field stored in the hierarchical information in a primary cache.
In this step, it is determined whether the target object a that the user wants to query belongs to the hot data, or it may be determined whether the target object a that the user wants to query is stored in the first-level cache. The thermal data is determined based on the traffic demand of the energy storage system. In one embodiment, the thermal data includes common data/fields in the hierarchy information of the energy storage hierarchy determined according to the traffic demand, such as a user name. The first-level cache is used for storing temporary data, so that the frequency of accessing the information source of the energy storage system by the server can be reduced, and the running performance is improved. The data in the first-level cache is the copy of the data in the energy storage system information source, the server reads and writes the data from the first-level cache during operation, and the data of the energy storage system information source and the server can be synchronously cached at a specific moment or when an event occurs.
And S30, if so, acquiring the energy storage system information of the target object from the primary cache and feeding back the information to a user. In this step, the thermal data is a field stored in the level information in the level one cache, such as a user name, an address, a telephone, a mail or other identification information, and may also be a model number, an accumulated usage time, a lifetime or other identification information of the battery cell. At certain times or under certain conditions, which field the hot data belongs to in the hierarchical information is alterable.
And S40, if not, searching the hierarchy information of the target object from the first-level cache according to the identification information of the energy storage system to which the target object belongs in the user access token. The hierarchy information of the target object is the structure information of a hierarchy tree to which all target objects stored in the secondary cache belong. And the hierarchical tree to which each target object belongs is distinguished by the identification information of the energy storage system to which the target object belongs.
In this step, the energy storage system information of the target object does not belong to the thermal data, and is not stored in the primary cache, and the energy storage system information of the target object cannot be found by traversing the storage content in the primary cache. At this time, the level information of the target object needs to be searched from the primary cache according to the user access token. The user access token includes identification information of a top-level object to which the target object belongs, such as an ID code, a serial code, and the like, which can uniquely identify the top-level object information to which the target object belongs. Therefore, the level information of the target object can be searched from the first-level cache by the user access token. The hierarchy information is structural information of a hierarchy tree to which all the objects stored in the secondary cache belong. And the hierarchical tree to which each target object belongs is distinguished by the identification information of the energy storage system to which the target object belongs.
S41, searching complete information of the target object from the hierarchical tree stored in the secondary cache according to the hierarchical information of the target object, and feeding the complete information back to a user; the hierarchical tree takes the complete information of the top-level object of the energy storage system to which the target object belongs as a root node, and takes the complete information of the sub-level objects below the top-level object as sub-nodes.
The hierarchical tree takes the complete information of the top-level object as a root node, and takes the complete information of the sub-level object under the top-level object as a child node. The hierarchical tree of each top level stored in the level two cache may have different forms. Such as: the complete information of the top-level object A and the sub-level objects thereof is stored in the form of a red-black tree (in the hierarchical tree of the top-level object A, the number of the sub-level objects of one node is more than 8). And storing the complete information of the top-level object B and the sub-level objects thereof in a binary tree form (in the hierarchical tree of the top-level object B, the number of the sub-level objects of one node is less than or equal to 8). When the number of the sub-level objects under the top-level object B changes (for example, the number of the sub-level objects increases), the detailed information of the top-level object B and the sub-level objects thereof is stored in the form of a binary tree before, and the detailed information of the top-level object B and the sub-level objects thereof is also stored in the form of a red-black tree. In the previous step, the hierarchy information of the target object is obtained from the first-level cache, and in the present step, the complete information of the target object is found from the second-level cache according to the hierarchy information of the target object and is fed back to the user. The information stored in the secondary cache is complete information of a more detailed energy storage system. Because the level information of the target object is mastered, when the complete information of the target object is searched from the secondary cache, the complete information of the target object is easier to find accurately, the query time is short, and the query efficiency is higher.
The hierarchical processing method for the energy storage system information provided in the embodiment includes: and receiving an access request of a user and generating a user access token, wherein the access request is used for inquiring the energy storage system information of the target object. The energy storage system information of the target object comprises the hierarchy information of the target object and the complete information of the target object. The user access token comprises identification information of an energy storage system to which the target object belongs. And judging whether the target object information belongs to the thermal data. And if so, acquiring the energy storage system information of the target object from the primary cache and feeding back the information to the user. If not, the level information of the target object is searched from the first-level cache according to the identification information of the top-level object to which the target object belongs in the user access token. And searching the complete information of the target object from the secondary cache according to the level information of the target object and feeding back the energy storage system information of the target object to a user. In the application, the storage and the quick query of the energy storage system information in the energy storage system are realized by adopting a secondary cache mode. The energy storage system information includes hierarchical information and integrity information of a plurality of energy storage hierarchies. On one hand, the occupied space of the level information of each energy storage system stored in the first-level cache is small, so that the query speed of the energy storage system information of the target object can be greatly improved. On the other hand, the complete information of the target object in the second-level cache is quickly positioned through the hierarchical information of the target object in the first-level cache, and the query efficiency is obviously improved. On the other hand, when the energy storage system information is inquired, whether the energy storage system information of the target object belongs to the thermal data or not is judged, and the energy storage system information of the target object is improved.
The method and the system for processing the energy storage system information in the grading mode combine the data characteristics of the energy storage system in the energy storage system, reasonably divide the information to be stored in the energy storage system into the hierarchy information and the complete information, and establish the relationship between the hierarchy information and the completion information for storage. According to the hierarchical processing method for the energy storage system information, in the process of inquiring an energy storage system, whether the energy storage system information of a target object belongs to thermal data or not is judged: if yes, acquiring the information (the energy storage system information of the target object) from the primary cache; if not, the hierarchy information of the target object is searched from the first-level cache, and then the complete information of the target object is searched from the hierarchy tree stored in the second-level cache according to the hierarchy information of the target object and fed back to the user.
According to the hierarchical processing method of the energy storage system information, a data structure of a second-level cache is set for storing the information of each energy storage system in the energy storage system. According to the method, the energy storage system information is stored through a data structure of the secondary cache, and the energy storage system information can be rapidly inquired. On one hand, because the level information of the top level object and each sub-level object in the energy storage system occupies small space, the query speed of the energy storage system information of the target object can be greatly improved; on the other hand, the complete information of the target object in the second-level cache can be quickly positioned through the hierarchical information of the target object in the first-level cache, and the query efficiency is remarkably improved.
In one embodiment, before step 10, further comprising:
and S01a, storing the hierarchy information of the top level object and the sub-level objects arranged below the top level object in a first-level cache in a red-black tree form. The hierarchical information comprises the identification information of each sub-object of the top object and a plurality of fields of information which are most frequently visited by users. In this step, a plurality of red and black trees may be stored in the first-level cache, as shown in fig. 2. Fig. 2 shows 3 red-black trees exemplified by a top 1, a top 2, and a top n, n being a positive integer. The root node of each red-black tree represents a vertex. The intermediate nodes under the root node represent children under the top class. And the rest is repeated until all the substages of the top substage are completely counted to the red and black tree. Typically, the total number of layers of a topping is between 4 and 8, and in most cases no more than 5. In a specific embodiment, the format of the hierarchy information may be: the ID of each layer information source is spliced and separated by '-' in the middle. In another specific embodiment, the format of the hierarchy information may be: the coded concatenation of stack-cluster-cells, separated by '-'s in the middle (the energy storage architecture comprises three stages, not shown).
And S01b, storing complete information of the top level object and the sub-level objects arranged below the top level object in a secondary cache in a hierarchical tree form, wherein the hierarchical tree comprises a red-black tree or a binary tree form. In this step, the second-level cache stores the top-level object and the complete information of the sub-level objects arranged under the top-level object in the form of a hierarchical tree. The hierarchical tree may be in the form of a red-black tree or a binary tree. Multiple hierarchical trees may be stored in the level two cache as shown in fig. 3. Two hierarchical trees of a topstock m1 and a topstock m2 are illustrated in fig. 3, where m1 and m2 are positive integers and m1 and m2 are less than or equal to n.
In this embodiment, the content cached in the first-level cache and the second-level cache is energy storage system information (i.e., hierarchy information and complete information of a plurality of energy storage systems). Specifically, the first-level cache stores the hierarchy information of the energy storage system. And the second-level cache stores complete information of the energy storage system. The first-level cache and the second-level cache can select cache middleware such as Varnish, ngnix, squid, memcache, redis, ehcache and the like.
In addition, in the embodiment, in the process of data processing of the energy storage system information, the data processing speed can be effectively increased by adopting the number of the caches and the types of the data stored in the caches. According to the method, the first-level cache and the second-level cache are arranged, and different data types are stored in different caches, so that the data query speed and the query efficiency of the energy storage system information can be greatly improved.
In one embodiment, the user access token includes identification information of an energy storage system to which the target object belongs, and the identification information is an ID code of a top-level object of the energy storage system to which the target object belongs. The step of S40 then includes:
and traversing the hierarchy information of all the top-level objects stored in the first-level cache according to the ID codes of the top-level objects of the energy storage system to which the target object belongs until the hierarchy information of the top-level objects of the energy storage system to which the target object belongs is found.
In this embodiment, each red-black tree stored in the first-level cache and each hierarchical tree stored in the second-level cache use the top-level object ID as a number. In the data storage stage, the top-level object ID is stored in the token after being authenticated. When a user accesses (when the user inquires the target object information), after the token is sent to the accessed user, the user puts the token into a request header of an access request to inquire data. And traversing all the red and black trees stored in the first-level cache until the level information of the target object is found according to the ID code of the top-level object to which the target object belongs as the query mark.
In one embodiment, the root node of each hierarchical tree uses the topsides ID as a number, the root node storing the complete information for the topsides.
In the hierarchical tree, the lower-level child nodes of the root node store complete information of the secondary object, and all nodes in the lower-level child nodes are orderly. It is understood that the lower level child node set of the root node is considered as a node as a whole, and the siblings of the node are ordered.
In the hierarchical tree, the next subordinate child node of the subordinate child node stores the complete information of the three-level object, and all nodes in the next subordinate child node are orderly. It is understood that the collection of subordinate child nodes of a subordinate child node is considered as a node as a whole, with the siblings of this node ordered among themselves.
And repeating the steps until all subordinate objects under the top object are stored.
In this embodiment, the hierarchy of the subordinate objects under the top object is not limited, and may be set according to the number/hierarchy relationship of the subordinate objects in the actual energy storage system. The hierarchical tree also takes the ID of the top-level object as a tree root node, all the sub-level object information under the top-level object is positioned in the same level of the same hierarchical tree, and the sub-level object information in the hierarchical tree is stored in a structure of a binary tree or a red-black tree.
In one embodiment, at most complete information including five levels of objects is stored in the hierarchical tree. For example, complete information of three levels of energy storage structures is stored in the hierarchical tree; storing complete information of four levels of energy storage states in the hierarchical tree; storing complete information of a five-level energy storage structure in the hierarchical tree. Specifically, referring to fig. 3, each of the topsides m1 and m2 in fig. 3 includes 4 layers. Such as the top grade m2; secondary 2, secondary 3, secondary 4; tertiary 5, tertiary 6, tertiary 7, tertiary 8, tertiary 9, tertiary 10 and tertiary 11; quats 12, 13, 14, 15, 16, 17, 18, 19, 20.
In one embodiment, the hierarchical tree is dynamically updated using a least recently used page replacement algorithm.
In this embodiment, the hierarchy tree as a whole is dynamically replaced/updated by the LRU algorithm to ensure the hit probability of the hierarchy tree in the memory. The LRU algorithm is an abbreviation of Least Used by the Least Recently Used page replacement algorithm, is Used for virtual style storage management service, and is decided according to the use condition of pages called into a memory. Since the future use of each page cannot be predicted, only the "recent past" can be used as an approximation of the "recent future".
In one embodiment, when the number of the sub-level objects of the same node is less than or equal to 8 in the hierarchical tree, the complete information of the node and the sub-level objects thereof is stored in a binary tree form. In the hierarchical tree, when the number of the sub-level objects of the same node is more than 8, the complete information of the node and the sub-level objects thereof is stored in a red and black tree form.
In this embodiment, the hierarchical tree in the second-level cache is stored in a red-black tree form or a binary tree form, and the system can convert itself. The conversion process from the binary tree to the red-black tree is to traverse the original binary tree and process the data of the original binary tree according to the requirements of the red-black tree. The five basic requirements of the red and black tree are fixed, and no new data processing rules need to be designed. The conversion from the binary tree to the red-black tree is determined according to whether the number of the nodes is larger than 8, and the system program can automatically convert the binary tree into the red-black tree when the number of the nodes is larger than 8 so as to ensure the time complexity of query.
In one embodiment, when each level in the energy storage system is added or deleted, the level information stored in the first level cache (in the red and black trees) is modified correspondingly. And when each level object in the energy storage system is added or deleted, the complete information of each level object is correspondingly added or deleted in the second level cache (in the hierarchical tree).
In this embodiment, the first-level cache stores the hierarchy information of each level in the energy storage system, and the data volume is relatively small. Moreover, when each level of objects is added or deleted in the red and black tree in the first-level cache, not all the red and black trees are updated, but basically, part of the red and black trees are adjusted. In addition, in this embodiment, elimination of sub-nodes in the hierarchical tree in the second-level cache is actually control on granularity, and since the entire hierarchical tree itself is limited (the number of each level is 5 levels at the highest) in some embodiments, the number of nodes is not too large, and when complete information of each level is added or deleted from the hierarchical tree, the reading speed of the energy storage system information is not greatly affected.
In one embodiment, the level information is a concatenation of the top level object ID and the sub-level object ID set under the top level object, separated by a '-' in between. Specifically, the hierarchy information is typically stored in a common language specification (cls field). Such as: the hierarchy information may be the ID of the top-level-ID of the secondary-ID of the tertiary. In another aspect, the level information refers to the number of layers included in a certain storage tree structure (e.g., a red-black tree in a first-level cache) and the number (which may be an ID number) of each level in the energy storage system in each layer.

Referring to fig. 5, in one embodiment, an energy storage system is taken as an energy storage dealer, and an energy storage dealer system includes a top dealer and a plurality of sub-dealers. The energy storage system information includes hierarchical information of the dealer and complete information of the dealer. Each sub-dealer under a dealer belongs to the same hierarchy, and all sub-dealers under the dealer are divided into a hierarchy. Thus, all child dealers can be determined by locating the parent dealer. In order to facilitate the search for a particular one of the child distributors, the child distributors within the hierarchy are stored in a binary tree or red-black tree structure.
One top level dealer corresponds to one red-black tree and one hierarchical tree. The corresponding red and black trees are stored in the first level cache, and the corresponding hierarchical tree is stored in the second level cache. It may be provided that the dealer's hierarchy information (including hot data determined according to business requirements) is stored in the form of a red and black tree in the level one cache. For example, user name information in the hierarchy information may be set as the hot data.
Specifically, one dealer a, after authentication, will store the ID of the top dealer of dealer a in the token. (1) If this dealer a only inquires about its own hierarchical information or name (hot data), it only needs to find the corresponding red-black tree in the level one cache according to the ID of the top level dealer, and then traverse the dealer a in the red-black tree. (2) If dealer A were to query other dealer B's hot data, it would be necessary to determine the Red-Black Tree from the ID of the other dealer B's top dealer, and then traverse the Red-Black Tree. (3) If the dealer a needs to inquire the complete information of the other dealers B, the red-black tree needs to be determined according to the IDs of the top-level dealers of the other dealers B, and then the complete information of the other dealers B is found from the hierarchical tree stored in the secondary cache according to the hierarchical information of the other dealers B recorded in the red-black tree. (4) If the dealer A needs to search the mobile phone number of the lower-level sub-dealer, complete information such as Email needs to search the hierarchical information of the dealer A according to the ID of the top-level dealer in the corresponding red and black tree. And then, according to the hierarchical information recorded in the red and black tree, finding a parent node on the hierarchical tree, wherein the parent node is associated with complete information of all subordinate dealers. So as to search the complete information of the subordinate sub-dealer of the dealer A from the hierarchical tree stored in the second-level cache.
In the application, the hierarchical processing system of the energy storage system information adopts a secondary tree structure to store and query hierarchical dealer data. The secondary tree structure includes a primary tree storing hierarchical information of the dealer and a secondary tree storing complete information of the dealer. The first-level tree is a red-black tree, and the second-level tree is a red-black tree or a binary tree. The first level tree is stored in a first level cache (resident memory) and the second level tree is stored in a second level cache (accessible memory). The data structure of the second-level cache is set for storing data of the hierarchical dealer of the energy storage system. The data processing process of the energy storage system hierarchical dealer and the data structure of the second-level cache are combined into practical application, and the data of the energy storage system hierarchical dealer can be quickly inquired. On one hand, the hierarchical information of the dealer occupies small space, so that the query speed of the target object can be greatly improved; on the other hand, the complete information of the target object in the second-level cache can be quickly positioned through the hierarchical information of the target object in the first-level cache, and the query efficiency is remarkably improved.
