Including: an invoice storage unit, an invoice scanning unit, an invoice information confirmation unit, and an invoice verification unit; the invoice verification unit is used to receive the invoice information output by the invoice scanning unit and / or the invoice information confirmation unit, and call the invoice pool or tax The corresponding information of the system is checked for authenticity by comparison, and the result of the authenticity check is obtained and recorded. Through the invoice inspection unit, the authenticity inspection of batch invoices is realized, the inspection efficiency of the equipment is improved, and the error rate is reduced.

The invention discloses a payment system and a payment method based on a USSD (Unstructured Supplementary Service Data) communication protocol, wherein the payment system comprises a system master station, a mobile terminal, a user terminal and an operator terminal, the user terminal is used for initiating a charge request to the system master station through network communication, the system master station is used for receiving the charge request initiated by the user terminal, an App which is capable of communicating with the system master station and has a USSD dialing function is installedon the mobile terminal, the mobile terminal is used for performing USSD dialing after obtaining a charge task, performing transfer charge to the operator terminal through the USSD protocol, and monitoring a charge result and returning the charge result to the system master station; and the system master station is used for generating a charge TOKEN code according to the charge result returned from the mobile terminal and returning the charge TOKEN code to the user terminal. Through adoption of the application scheme of the payment system, the mobile terminal is used as a service terminal, thereby facilitating achievement of complicated business, and also providing an integration scheme for an API (Application Programming Interface) interface.

The invention discloses a method and a device for establishing a table entry of a flow table. The method for establishing the table entry of the flow table comprises the following steps of: dividing extracted content information into at least two subsets; corresponding all or part of the subsets to unique mapping values; and generating a key word of a to-be-established table entry according to the mapping value corresponding to each subset in all or part of the subsets so as to further generate the to-be-established table entry. The invention also discloses a method and a device for querying the table entry of the flow table; and the method comprises the following steps of: extracting content information for querying the key word of the to-be-queried table entry from a received message; querying the mapping value corresponding to each subset in all or part of the subsets of the extracted content information; and generating the key word of the to-be-queried table entry according to thesearched mapping value and querying the corresponding table entry from the flow table through the generated key word. Because both the length of each subset and the length of the key word for generating the flow table are less than the maximum length which can be processed by a network processor, the network processor can realize the functions of establishing and querying the table entry of the flow table containing the complex key word.

The embodiment of the invention provides a we media transmission atlas analysis method and device based on vector query. The method mainly comprises the following steps: collecting media information transmitted by all kinds of media transmission platforms in we media, constructing a query statement related to an event theme, querying the document data of the media information by utilizing the vector of the query statement, and outputting a document collection related to the event theme; conducting a similarity analysis on documents in the document collection, and generating a tuple data set according to results of the similarity analysis; showing articles in the tuple data set on a geographic information system according to the longitude and latitude coordinates of the articles, and generating a transmission path of media information related to the event theme. The method and the device provided by the embodiment of the invention can perform comprehensive analyses on the media information transmission conditions of all we media platforms, achieve real we media transmission atlas analyses, and can achieve the function of querying the transmission analysis result of any event in we media.

The invention provides a two-dimensional dynamic contact inquiry list inquiring method and system based on a double-hash structure. The method includes that a contact inquiry hash list is built; the contact inquiry hash list comprises a contact inquiry non-name-duplication list and a name-duplication hash list; whether a name list has duplicate names is judged, and on no judgment, the non-name-duplication hash list is inquired; on yes judgment, the name-duplication hash list is inquired; data content of a required two-dimensional table is inquired in the non-name-duplication hash list, line marks and row marks of a two-dimensional array are determined according to fields of the required two-dimensional table and recorded names, and the data content is inquired according to the line marks and the row marks; data content of the required two-dimensional table is inquired in the name-duplication hash list, a new contact inquiry non-name-duplication hash list is generated by using indexes, line marks and row marks of the two-dimensional array are determined according to the fields of the required two-dimensional table and the recorded names, and the data content is inquired according to the line marks and the row marks. By means of the method and system, contact inquiry access efficiency is improved, and inquiry is quickened by using the line marks and the row marks of the hash location two-dimensional array.

The invention discloses a neighboring object index query method oriented to a road network communication scene. In the road network scene environment, a dynamic communication object neighboring index query with spatial characteristics is established (divided into a spatial index establishment process and a neighboring object index query process two). stage) and data communication between adjacent objects. The virtual grid Z code is used to divide the space to realize the rapid positioning of the communication object, the Delaunay triangulation and the Voronoi structure are used to determine the adjacent relationship, the adjacent Voronoi cells are found, the Z code value of the adjacent area of ​​the query object is obtained, and the Z code value is correlated with the communication object. It solves the problem of adjacent spatial index query of dynamic objects in specific road network scenarios and the problem of message transmission between adjacent objects, and realizes the dynamic target based on location service and its adjacent objects within a certain range around it. data communication between.

The invention discloses a data table storage method based on an automatic identification identifier. A data table based on an automatic identification identifier comprises data table header construction and data table recording construction; during the data table header construction, a data table header defines a data table identifier field at a starting line, and the data table identifier field meets the requirement of the automatic identification identifier on constructing data format; during the data table recording construction, for a plurality of data records of a storage data table after the data table head, the data records are stored by adopting a variable-length identifier field data table or a fixed-length identifier field data table. Compared with the identifier sequential storage structure, the variable-length identifier field data table or fixed-length identifier field data table storage scheme has the advantages that the storage space is saved, and great significance is realized on the automatic identification identifier with the limited storage space.
