Referring to fig. 1, fig. 1 is a flowchart illustrating steps of an automobile information interaction query method according to an embodiment of the present invention.

The invention provides an automobile information interaction query method, which is applied to an information interaction query platform, wherein the information interaction query platform comprises a client and a back-end server, and the method comprises the following steps:

step 101, responding to an operation instruction acquired by a client, selecting a plurality of target condition components from a condition component library to construct a retrieval condition graph;

the operation instruction refers to a trigger instruction such as clicking, selecting, dragging, connecting and placing input by a user at a client, and is used for selecting a plurality of target condition components from a condition component library and performing attribute editing and connection relation construction on each component.

In the embodiment of the invention, a user inputs an operation instruction on a client, for example, a plurality of target condition components are dragged in a condition component library of a client interface, and attribute values and connection relations corresponding to the target condition components are edited in the interface, so that a retrieval condition graph is constructed and obtained.

102, when the client receives the submission instruction, checking the retrieval condition graph through the client;

after the user finishes editing the retrieval condition graph, a submission instruction can be further input into the client, and after the client receives the input submission instruction, the retrieval condition graph is verified locally at the client to determine whether the retrieval condition graph has the conditions of unknown attribute values and/or unknown connection relations and the like, and whether the verification is passed is judged.

103, if the verification is judged to be passed, sending the retrieval condition graph to a back-end server through the client, and generating at least one condition retrieval queue according to the retrieval condition graph through the back-end server;

in an example of the present invention, if the search condition map does not have a case where the attribute value is unknown or the connection relationship is unknown, it is determined that the check is passed. At this time, the retrieval condition graph can be sent to the back-end server through the client, and at least one condition retrieval queue corresponding to the retrieval condition graph is determined through the back-end server according to the specific attribute values and the connection relation of the target retrieval components in the retrieval condition graph.

It should be noted that the client in the embodiment of the present invention refers to a consumer, a personal user terminal, a display terminal disposed on a backend server, and the like, for example, a mobile phone, a computer, a tablet, and the like. The condition searching queue includes condition nodes generated based on the target condition components, and the condition nodes have logical AND connection relation.

Step 104, searching a preset information database through the back-end server according to each condition search queue to generate information results corresponding to each condition search queue;

the information database refers to a database storing information data uploaded by a plurality of automobile information manufacturers, and can be divided into a cache library and a non-cache library, wherein the cache library is stored locally in a back-end server and is used for caching a condition retrieval queue with high search frequency and information results thereof, and the non-cache library is used for storing all information data uploaded by each automobile information manufacturer in a field form, such as articles, posters, videos or activities and the like associated with each automobile series.

After the back-end server generates at least one condition search queue according to the condition search graph, each condition search queue is analyzed, and information results meeting each condition search queue are searched from the information database.

And 105, generating a result list by adopting all information results through the back-end server and returning the result list to the client for rendering and displaying.

After the back-end server retrieves all information results, in order to facilitate visual checking by a user, all the information results can be uniformly constructed into a result list and returned to the client, and the client performs rendering display according to the result list to obtain a visual interface containing all the information results.

In the embodiment of the invention, a client of an information interaction query platform responds to an operation instruction input by a user, selects a plurality of target condition components from a condition component library built in the client and constructs a corresponding retrieval condition graph; after the retrieval condition graph is constructed, if a submission instruction input by a user is received, the retrieval condition graph can be further verified through the client to judge whether conditions such as unknown attribute values or wrong connection relations exist, if the conditions pass the verification, the retrieval condition graph is sent to the back-end server, at least one condition retrieval queue is generated through the candidate server according to target condition components in the retrieval condition graph and the connection relations of the target condition components, then the information database is decelerated according to the condition retrieval queue to generate corresponding information results, finally all the information results are returned to the client in a result list mode, and the client and the result list are used for rendering and displaying visual information results. Therefore, the retrieval efficiency and the retrieval flexibility of the user for retrieving the automobile information are improved through the visual operation of the retrieval condition component and the logical relation.

Referring to fig. 2, fig. 2 is a flowchart illustrating steps of an automobile information interaction query method according to a second embodiment of the present invention.

step 201, responding to an operation instruction acquired by a client, selecting a plurality of target condition components from a condition component library to construct a retrieval condition graph;

in the embodiment of the invention, a user can input an operation instruction at a client to select a plurality of target condition components from a condition component library in a client interface, and a retrieval condition graph is obtained by editing the attribute values of the target condition components and constructing the connection relation.

Fig. 3 is a schematic diagram illustrating a process of constructing a search condition map according to an embodiment of the present invention.

In one example of the invention, the condition component library can display a plurality of target condition components with higher use frequency in a top column, and other target condition components with lower use frequency can be inquired through an inquiry button, and simultaneously, the retrieval condition graph can be reset through a reset button.

Wherein each search condition component has four attribute values: 1. and the component node ID is used for determining the position of the retrieval condition component in the condition retrieval graph. 2. Node type, which is used to determine which search condition. 3. And the condition value is used for responding to user input to set the condition threshold value. 4. Comparison logic: by default equal, some conditions may be scoped queries such as price, date, etc., and comparison logic such as greater than number, less than number, etc. may be selected here. When the mouse hovers over the condition component, its condition-selectable value is displayed.

Optionally, each condition component in the condition component library may further distinguish the node type corresponding to each condition component by a different color.

Step 202, when the client receives the submission instruction, the retrieval condition graph is checked through the client;

optionally, step 202 may include the following sub-steps:

when the client receives the submission instruction, the client traverses the retrieval condition graph and judges whether an unconnected target condition component exists in the retrieval condition graph;

if not, inquiring whether the attribute values which are not added exist in each target condition component;

if not, judging that the search condition graph passes the verification;

and if the target condition components which are not connected exist in the search condition diagram or the attribute values which are not added exist in any target condition component, judging that the check of the search condition diagram fails, and generating an editing prompt.

In the embodiment of the present invention, after the search condition graph is constructed, if a submission instruction input by a user is further received, the search condition graph may be traversed by the client to determine whether each target condition component is not connected, if not, whether each target condition component has an attribute value that is not added may be further queried, and if not, it is determined that the search condition graph passes verification.

And if the target condition components which are not connected exist in the retrieval condition diagram or the attribute values which are not added exist in any target condition component, judging that the retrieval condition diagram fails to be verified, and generating an editing prompt to wait for further editing of the user.

In an example of the present invention, before the back-end server searches the search condition graph for the first time, a corresponding information database may be further constructed based on the basic information data uploaded by the automobile information terminal.

Optionally, the method may further comprise the following steps S11-S15:

s11, receiving basic information data uploaded by a plurality of automobile information terminals respectively, and creating access registration lists corresponding to the automobile information terminals respectively;

s12, classifying the basic information data according to the preset information type to obtain various intermediate information data and respectively constructing corresponding intermediate information tables;

s13, screening the intermediate information data in each intermediate information table according to the preset field name to generate a field information table;

referring to fig. 4, fig. 4 is a schematic diagram illustrating an information database construction process according to the embodiment.

In the embodiment, basic information data uploaded by a plurality of automobile information terminals such as automobile manufacturers, dealers and the like respectively can be received through the back-end server, and the content of the basic information data can include but is not limited to automobile series data, automobile model data and associated articles, posters, videos, activities and the like. And meanwhile, responding to the access of each automobile information terminal, distributing the corresponding access application ID, the access application key and the access name of each automobile information terminal, and respectively creating a corresponding access registration table.

In addition, the information can be classified according to the clustering information type of the input basic information data to obtain various intermediate information data and create corresponding intermediate information tables, for example, the automobile manufacturer A comprises a B automobile system, a C automobile system and a D automobile system, and the corresponding intermediate information tables can be respectively generated according to the automobile systems. Then, the intermediate information data is screened according to the plurality of field names set by the invention, such as access names, alias names, English names and the like, so as to obtain the intermediate information data meeting the requirements, and a field information table is generated.

S14, establishing the association among the access registration list, the intermediate information list and the field information list respectively to obtain a plurality of target information association lists;

further, the access registry comprises an access application ID, and S14 may comprise the sub-steps of:

creating a plurality of initial information association tables;

calculating a hash value corresponding to the ID of the access application;

acquiring an intermediate information ID corresponding to the intermediate information table and acquiring a field information ID corresponding to the field information table;

and respectively loading the intermediate information ID, the field information ID and the access application ID into the intermediate information association table to obtain a target information association table.

In the embodiment of the present invention, a plurality of initial information association tables may be created in the back-end server, hash values corresponding to access application IDs corresponding to each vehicle information terminal are respectively calculated, an intermediate information association table is selected from the plurality of initial information association tables according to the hash values, an intermediate information ID corresponding to the intermediate information table and a field information ID corresponding to the field information table are obtained, and the intermediate information ID, the field information ID and the access application ID are respectively loaded to the intermediate information association table to obtain a target information association table, please refer to fig. 4.

S15, constructing the information database by using the all-field information table and the target information association table.

In the embodiment of the invention, the information database is constructed by adopting all the field information tables and the target information association table.

It should be noted that, in the information query process of the client, a field information table is usually used for querying, and if there is no required field in the field information table, the corresponding intermediate information table may be further queried through the target information association table, so as to obtain the corresponding information from the intermediate information table.

Step 203, if the verification is judged to be passed, sending the retrieval condition graph to a back-end server through the client;

in the embodiment of the invention, if the check is judged to be passed, the retrieval condition graph can be sent to the back-end server through the client.

Specifically, the retrieval condition graph sent by the client to the backend server may include, but is not limited to, the following data: the first is that the information (connection information) of each target condition node includes a node id, a condition type, a condition threshold, and a condition logic. All types are obtained by traversing the components of the search condition style in the input box of the condition search graph. The second is a connection condition of the target condition node (condition node), which includes two parts, the former node id and the latter node id (default high position target condition node flows to low position target condition node).

Step 204, extracting connection information between every two target condition components from the retrieval condition graph through a back-end server; the target condition component includes a component node ID;

in an example of the present invention, after the back-end server obtains the retrieval condition graph, connection information between each two target condition components and component node IDs corresponding to the respective target condition components may be extracted from the retrieval condition graph.

Step 205, creating condition nodes corresponding to each component node ID and connecting according to the connection information to obtain a condition retrieval tree;

in one example of the present invention, a corresponding conditional node may be created according to each component node ID, and connected according to the connection information, thereby obtaining a conditional search tree.

In the specific implementation, a root node id (a node which is not set later in the condition node data of the condition retrieval graph) is found from the condition node data, a corresponding node is found in the connection information according to the node id, and the root node of the condition retrieval tree is constructed. The conditional nodes are then traversed to find the child nodes of the root node, and because of the multi-way tree nature, there may be multiple child nodes for a parent node. The node needs to be recorded for subsequent backtracking. The backtracking algorithm finds a path reaching the leaf from the root node, then backtracks, checks whether the father node of the node has other leaf nodes, adds the leaf nodes to the tree if the father node of the node has other leaf nodes, and continues to push downwards. If not, the grandfather node of the upper layer is traced back.

Step 206, traversing the conditional retrieval tree to generate at least one conditional retrieval queue;

in the embodiment of the invention, at least one condition retrieval queue can be generated by traversing each condition node in the condition retrieval tree.

Referring to fig. 5, fig. 5 is a queue diagram illustrating a conditional search queue according to an embodiment of the present invention.

In the embodiment of the invention, the recording is started from the root node by adopting a depth-first traversal + replication algorithm, if the node has a plurality of child nodes, the existing link is replicated, the child nodes are respectively added at the tail ends of the existing link, and finally the number of the conditional retrieval queues is consistent with the number of leaf nodes in the conditional retrieval tree, so that a plurality of conditional retrieval queues are obtained.

Optionally, before performing step 207, the method may further include the following steps S21-S23:

s21, traversing each condition retrieval queue, and judging whether the same node type exists in the same condition retrieval queue;

s22, if yes, deleting the condition retrieval queue, and returning a retrieval link to repeat the prompt to the client;

and S23, if not, reserving the condition searching queue.

In a specific implementation, the same node type may exist in the same conditional search queue due to a user editing error, for example, if an element of a repeated type occurs in one link, the user may input an error, because the relationship between parent and child nodes in the clue condition tree represents a logical and relationship, if the parent node condition is that the vehicle train is bmw and the child node condition is that the vehicle train is audi, the two nodes do not necessarily have an intersection, the joint result of the two nodes is empty, and the empty set in the link may be directly short-circuited because the empty set is a logical and.

Therefore, each condition retrieval queue can be traversed to judge whether the same node type exists in the same condition retrieval queue, if so, the condition retrieval queue is deleted to return a retrieval link for repeated prompt to the client, and if not, the condition retrieval queue is reserved to wait for subsequent retrieval of information results.

Step 207, retrieving a preset information database through the back-end server according to each condition retrieval queue to generate information results corresponding to each condition retrieval queue;

optionally, the conditional retrieval queue includes a plurality of queue nodes, the queue nodes having queue node IDs, and step 207 may include the following sub-steps S31-S34:

s31, searching each field information table in a preset information database by using each queue node ID as a main key through the back-end server, and judging whether a first key value corresponding to the queue node ID exists or not;

s32, if yes, obtaining the first key value from the field information table;

s33, if not, searching the target information association table according to the field information ID corresponding to the field information table, determining the corresponding intermediate information table and obtaining a second key value from the intermediate information table according to the queue node ID;

s34, after all the first key values and/or the second key values are obtained, determining the intersection of all the first key values and/or the second key values to obtain the information result corresponding to the condition retrieval queue.

In the implementation of the invention, each condition retrieval queue comprises a plurality of queue nodes, each queue node is provided with a queue node ID, each queue node ID is used as a primary key to retrieve each field information table in the information database through a back-end server so as to determine whether a first key value corresponding to the queue node ID exists, if so, the first key value can be obtained from the field information table and output as an information result, if not, a target information association table is selected from the information association tables according to the field information ID corresponding to the field information table, a corresponding intermediate information table is determined, and a second key value is determined from the intermediate information table. And after all the first key values and/or the second key values are obtained, determining the intersection of all the first key values and/or the second key values to obtain the information result corresponding to the condition retrieval queue.

Further, the information database includes a cache library; before performing S31, step 207 may further include the following sub-steps S41-S43:

s41, searching the cache library through the back-end server according to each condition searching queue, and judging whether a cache queue identical to the condition searching queue exists in the cache library or not;

s42, if yes, obtaining the buffer result corresponding to the buffer queue from the buffer library as the information result corresponding to the condition searching queue;

and S43, if the condition searching queue does not exist, splitting the condition searching queue into a plurality of queue nodes.

In another example of the present invention, the information database includes a cache library to further improve the efficiency of information result retrieval. The cache library can be retrieved through the back-end server according to each condition retrieval queue, whether the same cache queue exists in the cache library or not is judged, if yes, a cache result corresponding to the cache queue can be obtained from the cache library to serve as an information result, if not, the condition retrieval queue is split into a plurality of queue nodes, and step S31 is executed, so that all information results are retrieved.

Optionally, the cache library may update the cache queue according to a preset update period.

And step 208, generating a result list by the back-end server by adopting all information results and returning the result list to the client for rendering and displaying.

In another example of the present invention, the information result may be vehicle system data, activity data, etc., and after the user receives the information result at the client, the activity data may be further edited at the client, for example, an operation of registering an activity, etc., and returned to the back-end server, and the manufacturer obtains the activity registration information through the vehicle information terminal, so that the manufacturer knows that the user registers and records the activity.
