Detailed Description
The present invention is described below based on examples, but the present invention is not limited to only these examples. In the following detailed description of the present invention, certain specific details are set forth in detail. The present invention will be fully understood by those skilled in the art without the details described herein. Well-known methods, procedures, and flows have not been described in detail so as not to obscure the nature of the invention. The figures are not necessarily drawn to scale.
Fig. 1 is a block diagram showing the construction of a conventional logistics information processing system. Referring to fig. 1, the conventional logistics information processing system is composed of three subsystems, namely a waybill system (abbreviated as waybill), a transportation bill system (abbreviated as transbill) and a large-scale system (largeWaybill), each subsystem tracks the logistics responsible for itself in the whole course, and an interface provided separately and externally mainly queries logistics information according to the waybill number and informs a downstream system to acquire data by adopting an asynchronous mechanism.
In view of this, an embodiment of the present invention provides a method and a system for processing logistics information, and referring to fig. 2, the processing system integrates logistics information stored in three subsystems, namely, a waybill system (abbreviated as waybill), a transportation bill system (abbreviated as transbill), and a large-scale system (lagewayball), into a global tracking platform, and provides a query service and a downstream system docking service to the outside through the global tracking platform.
FIG. 3 is a schematic diagram of a module of a physical distribution information processing system used in the physical distribution whole course tracking process, and referring to FIG. 3, the physical distribution information processing system includes: the system comprises a basic configuration module, an adaptation module, a telephone operation matching module, a telephone operation analysis module, a data analysis module, a filtering module, a storage module, an early warning module, a service subscription module and an external notification module, wherein the functions of the modules are sequentially introduced in the following description.
Fig. 4 is a flowchart of a method for processing logistics information according to an embodiment of the present invention, and referring to fig. 4, the method for processing logistics information by using the logistics information processing system includes:
step S101, obtaining logistics information from a business system through a first interface.
It should be noted that, referring to fig. 5, the service system 2 is an upstream system of the logistics information processing system 1, is a system storing logistics information, and may include the foregoing bill system and the bill system, and other external systems (e.g. a large-scale system), so as to facilitate flexible receiving of the logistics information of any external system.
Step S102, for each display platform, performing speaking matching on the logistics information by adopting a speaking template so as to obtain speaking information matched with the display platform.
Specifically, the speaking template is corresponding to the display platform, and the speaking information matched with the display platform is obtained by using the speaking template corresponding to the display platform to perform speaking matching on the logistics information.
It should be noted that, the speaking information is dialogue information that is converted by using the crowd as the dialogue object in the specific display platform, and is a data that is introduced in the current logistics industry for the purpose of facilitating the understanding of the clients of the display platform and improving the experience of the clients, including B data, C data, I data, and the like. For example, the logistic information is "package in state transit center company", and if the display platform is merchant-oriented, the verbal information may be "package sent to state transit center company"; if the display platform is customer-oriented, the session information may be "package has arrived at state transit center company".
Step S103, pushing the conversation information required by the application system through the second interface.
It should be noted that, referring to fig. 5, the application system 3 is a downstream system of the logistics information processing system 1, which is a system for calling the speaking information, and may be a downstream system of the logistics information processing system 1, such as an order front desk, a sorting center, a crowdsourcing platform and other downstream terminals; but may also include, but is not limited to JOS and some order subscription systems.
Specifically, referring to fig. 5, the application system 3 may obtain, by means of service subscription, the service subscription module login permission of the logistics information processing system 1 and then request the required session information from the logistics information processing system 1, for example JOS; the physical distribution information processing system 1 may send the session information to the application system 3 in a notification manner through an external notification module, for example, a system downstream of the physical distribution information processing system 1.
According to the logistics information processing method provided by the invention, any logistics information is converted into the corresponding conversation information of the display platform through conversation matching processing, so that one processing system can uniformly acquire and process the logistics information and the conversation information required by the pushing application system, namely, one processing system uniformly provides services to the outside, so that great resources are saved in terms of usability and convenience of operation and maintenance of the system, and the technical problem that the traditional logistics information processing system consumes more resources in terms of operation and maintenance is solved.
Since the data formats of the logistics information received from different service systems are different, in order to adapt to the modification of the services of each existing service system in a unified manner, referring to fig. 5, the adaptation module of the logistics information processing system 1 is configured to convert the logistics information into the logistics information in the preset data format, so that the logistics information in the preset data format is unified for performing speaking matching in step S102. Accordingly, referring to fig. 6, in an alternative embodiment, the method for processing logistics information further includes: carrying out data verification on the logistics information received from the service system through the adaptation module so as to determine whether the logistics information is qualified data; under the condition that the logistics information is qualified data, acquiring an operation type and a source platform matched with the logistics information from a basic configuration module; according to the matched operation type and source platform, converting the logistics information into logistics information in a preset data format, and transmitting the logistics information obtained after conversion to the step S102, so as to perform speech matching on the logistics information in the preset data format in the step S102. The operation type refers to operation information in the process of generating the logistics information, for example, operators uploading the logistics information, departments to which the operation belongs, and the like.
It should be noted that:
(1) The qualified data is data which does not comprise dirty data, wherein the dirty data refers to that the data in the source system is not in a given range or is meaningless for actual business, or the data format is illegal, and the unnormalized coding and ambiguous business logic exists in the source system;
(2) The operation type and the source platform of the group correspond to one data format, and the original data format of the logistics information is obtained after the operation type and the source platform of the logistics information are obtained, so that the logistics information can be quickly converted into a preset data format;
(3) The preset data format is the preset data format of the logistics information processing system.
In the embodiment of the invention, the logistics information is firstly checked, and then the logistics information is converted into the logistics information with the unified preset data format, so that the adaptation process of the legal data to the logistics information processing system is realized, and the subsequent unified processing and maintenance of the logistics information are facilitated.
Referring to fig. 7, in an alternative embodiment, step S102, for each display platform, performs a speaking match on the logistics information using a speaking template to obtain speaking information matched with the display platform, including:
step S201, determining the state category of the waybill in the logistics information according to the logistics information.
The status type of the waybill includes, for example, already in warehouse, in transit, arriving at the transit center, already distributed, and the like.
Step S202, determining a speaking template according to the state type and the display platform.
Specifically, referring to fig. 8, this step may read matching rules from the template configuration table by a speaking matching module, and then, after the rule engine (e.g., drools, velocity) is initialized, execute the matching rules by the rule engine to determine the speaking template of the logistics information. Wherein reading the matching rule from the template configuration table comprises: a file path (e.g., in url) storing the matching rule in a database (e.g., mySQL) is obtained, and the file storing the matching rule is stored in the Jss, so that the matching rule is read from the Jss after the file path storing the matching rule is obtained. In the database, a set of state classes and display platforms correspond to a file path, and a matching rule is stored in a file path, so that a set of state classes and display platforms correspond to a matching rule (i.e., the matching rule is set according to the state classes and display platforms), and the file path is determined according to the state classes and display platforms so as to obtain the corresponding matching rule. It should be noted that, if the speaking template cannot be output after the rule is executed, the format difference between the rule engine and the matching rule is large, and the rule engine needs to be initialized again after the matching rule is set by the rule reset to output the speaking template.
Step S203, obtaining the speaking information according to the logistics information and the speaking template.
Referring to fig. 9, in this step, the speaking operation analysis module performs data verification on the logistics information to determine whether to perform speaking operation information conversion on the same logistics information, under the premise of ensuring anti-duplication, an analysis engine (for example, a relationship engine), analysis template rules and analysis data rules are obtained from a basic configuration service provided by the basic configuration module, the logistics information is analyzed by the analysis engine based on the analysis data rules and the speaking operation template is analyzed based on the analysis template rules, and then the analyzed logistics information is set at a corresponding position in the speaking operation template according to the analysis result of the speaking operation template, so as to obtain the speaking operation information.
In the embodiment of the invention, the speaking matching template further corresponds to the current state category of the logistics information, so that the speaking matching is realized through the speaking matching template, thereby being beneficial to improving the efficiency of speaking matching and improving the accuracy of speaking information.
Referring to fig. 10, in an alternative embodiment, the method for processing logistics information further includes: judging whether a conversation template is stored in a template configuration table through a filtering module; judging whether similar data of the logistics information is stored in the whole course tracking table according to a preset rule under the condition that a speaking template is stored in the template configuration table; and under the condition that similar data is not stored in the whole course tracking table, executing step S102, and performing speaking matching on the logistics information according to the display platform of the logistics information. The template configuration table and the global tracking table may be stored in the same database.
Furthermore, the preset rules can be customized according to the requirements, and can be set to be similar data of the logistics information, namely, similar data meeting the five-in-one principle with the logistics information is not subjected to repeated speaking and operation matching operation.
It should be noted that, the template configuration table stores a plurality of speaking templates, each speaking template corresponds to a group of state types and display platforms, so that whether the corresponding speaking template exists or not can be searched according to the state types and the display platforms; the whole-course tracking table stores a plurality of sets of logistics information, each logistics information has a corresponding conversation template, but the plurality of logistics information can use the same conversation template, so that the conversation template is less than the logistics information, and the information content of the conversation template is less than the logistics information.
Specifically, in the case where the speaking template is not stored in the template configuration table, similar data without the logistics information is described; in the case that similar data is stored in the whole course tracking table, it is explained that the current processed logistics information may be the logistics information repeatedly submitted by the misoperation of the staff, so that repeated speaking operation matching operation is not performed on the logistics information.
According to the embodiment of the invention, the similar data of the logistics information is filtered, so that the quantity of the logistics information to be processed is reduced, particularly, the logistics information repeatedly submitted by misoperation of workers is effectively processed, and in the process of filtering the similar data of the logistics information, a speaking and operation template is searched through a template configuration table first, and then the similar data of the logistics information is searched through a whole-course tracking table, so that the filtering of the same logistics information is realized at a higher query speed.
Referring to fig. 11, in an alternative embodiment, step S103 of pushing, through the second interface, the session information required by the application system includes performing, through the data parsing module, the following steps:
acquiring an attribute list from a data configuration table according to the waybill state and the display platform of information required by an application system (the data configuration table can be stored in a database);
under the condition that the attribute list is obtained, analyzing the dialogue information to extract attribute values of the attributes in the attribute list;
assembling the attribute and the corresponding attribute value in the attribute list to obtain assembled data;
the assembly data is pushed to the downstream application system through the second interface.
It should be noted that, the data configuration table stores the corresponding relation between the waybill state and the data set of the display platform and the attribute list, and the corresponding relation can be customized according to the application system.
The embodiment of the invention mainly collects the data of the application system which is required to be notified by the node characterized by the call operation information, provides a specific implementation mode for pushing the call operation information required by the application system, stores the corresponding relation between the data group of the waybill state and the display platform and the attribute list in the data configuration table, acquires the attribute list of the information required by the application system through the data configuration table, and further rapidly assembles the required information of the application system.
In an alternative embodiment, the speaking information includes a plurality of sub-speaking information categorized by the presentation platform; after obtaining the conversation information matched with the logistics information, the logistics information processing method further comprises the following steps: the plurality of sub-microphone information classifications are stored in different memory locations.
For example, referring to fig. 12, where the sub-phone information includes B data for a merchant and C data for a customer, the method for processing the logistics information further includes storing the B data in the Hbase storage module and the C data in the database storage module after the storage module distributes the B data using the storage mode.
In the embodiment of the invention, the heterogeneous data source clustered storage mode is used, so that the storage, reading and maintenance of the conversation information are mutually independent, and the high reliability and high availability of the service are ensured.
In an optional embodiment, the method for processing logistics information further includes executing, by the early warning module, the following steps:
acquiring a pre-warning rule of logistics information;
judging whether the transportation information in the logistics information meets the preset standard according to the early warning rule;
and under the condition that the transportation information does not accord with the preset standard, generating an early warning record according to the effective mechanism, and sending the early warning record according to the sending rule.
Specifically, the transportation information includes a transportation track, a transportation node time, and the like. Referring to fig. 13, the foregoing early warning rule, validation mechanism and sending rule may be set by a basic configuration service of the logistic information processing system before use, and after the sending rule is set, the early warning record may be sent out according to the sending rule, where the early warning rule specifies a predetermined standard of transportation information, and the setting of the early warning rule includes: creating an early warning rule and binding the early warning rule to the two links of the transportation node; the effective mechanism prescribes the generation time of the early warning record and the content of the early warning record; the sending rule prescribes a receiving terminal of the early warning record and a receiving and transmitting mode of the early warning record.
The method for processing the logistics information aims at monitoring and early warning the logistics information, and the logistics information can be generated by all nodes in the cargo transportation process, so that the method for processing the logistics information achieves early warning of the whole-course tracking nodes.
In the above description of the method for processing logistics information, the roles of the modules of the logistics information processing system shown in fig. 3 are described, it should be noted that the logistics information of the large-scale system and the data to be processed of the logistics information processing system may have the same format, so that the data format conversion is not required to be performed through the adaptation module, and the session information obtaining device of the large-scale system may be configured to notify the module through the external notification module, where the interactions between the modules of the logistics information processing system are shown in fig. 14.
