Description

A kind of data acquisition process solution based on RFID and SASE

Technical field

The present invention relates to a kind of data acquisition process solution based on RFID and SASE.

Background technology

Since 20 century 70s, food-safety problem becomes increasingly conspicuous, and causes the extensive concern of people.Carry out agricultural product security mark and tracing management, setting up agricultural product traceability system is the important measures effectively solving food-safety problem.Although traditional contact recognition technology technical costs is low, needs a large amount of manual operation, add the cost of agricultural product.

Due to quick, the accurate and non-contacting feature in REID acquisition of information aspect, cause the revolution of a supply chain, be the more recent application of current era infotech in global article code, logistics, automatically dispensing, receive the unprecedented concern in the whole world and even various circles of society.

Summary of the invention

The defect that the present invention seeks to exist for prior art provides the method that a kind of RFID of utilization and SASE carries out agricultural product data acquisition and inquiry.

The present invention for achieving the above object, adopt following technical scheme: a kind of data acquisition process solution based on RFID and SASE, comprise data acquisition and data processing, the method sticks RFID label tag before agricultural product go into circulation, at each Node configuration data collection point of Circulation of Agricultural Products, the label data collected is uploaded to internet by each data collection point, data filtering and elementary event integration is carried out in internet, the elementary event of continuous generation forms flow of event, and flow of event carries out Complex event processing and the storage of necessary event at server.

Preferably, described RFID label tag comprises EPC code, and described EPC code is the unique encodings of agricultural product in circulation, can not change in the process of circulation.

Preferably, each data collection point is provided with rfid interrogator, for writing RFID label tag data.

Preferably, it is by label data stored in Hash table that data filtering and elementary event are integrated, in Hash table, carry out duplicate removal filtration and event filtering, after the data through filtering are carried out buffer memory, by EPC system, Data Integration is become elementary event, elementary event is carried out buffer memory.

Preferably, Complex event processing can realize following functions:

A, real-time query, by the continuous Query statement be made up of SASE language compilation, Real-Time Monitoring event;

B, extraction interesting event, by the interesting event query statement be made up of SASE language compilation, extract interesting event;

C, complicated continuous Query, in conjunction with real-time query and extraction interesting event function, by corresponding event stored in event database.

Beneficial effect of the present invention: the program improves information acquisition efficiency in Circulation of Agricultural Products process, improves event handling efficiency; The utilization of non contact angle measurement technology, without the need to too much manual operation, saves manpower; Adopt the RFID label tag only comprising EPC code to reduce the cost of the method, improve adaptation of methods; The method can also realize the Real-Time Monitoring to agricultural product, once go wrong, can find immediately to solve.

Embodiment

Figure 1 shows that a kind of data acquisition process solution based on RFID and SASE, comprise data acquisition and data processing, the method sticks RFID label tag before agricultural product go into circulation, at each Node configuration data collection point of Circulation of Agricultural Products, the label data collected is uploaded to internet by each data collection point, data filtering and elementary event integration is carried out in internet, the elementary event of continuous generation forms flow of event, and flow of event carries out Complex event processing and the storage of necessary event at server.Described RFID label tag comprises EPC code, and described EPC code is the unique encodings of agricultural product in circulation, can not change in the process of circulation.Each data collection point is provided with rfid interrogator, for writing RFID label tag data.It is by label data stored in Hash table that data filtering and elementary event are integrated, in Hash table, carry out duplicate removal filtration and event filtering, after the data through filtering being carried out buffer memory, by EPC system, Data Integration being become elementary event, elementary event is carried out buffer memory.Complex event processing can realize following functions: a, real-time query, by the continuous Query statement be made up of SASE language compilation, and Real-Time Monitoring event; B, extraction interesting event, by the interesting event query statement be made up of SASE language compilation, extract interesting event; C, complicated continuous Query, in conjunction with real-time query and extraction interesting event function, by corresponding event stored in event database.

Before Circulation of Agricultural Products, stick RFID label tag, comprise EPC code in RFID label tag, EPC code is the unique encodings of agricultural product, can not revise in Circulation of Agricultural Products process; Be arranged on the rfid interrogator of Circulation of Agricultural Products node, can by non contact angle measurement technology, after the RFID label tag identification of circulating at this node, data are passed to internet, then the data of multiple node are carried out filtration to integrate, the tables of data of each RFID label tag is shown as R by data filtering module, O, T is stored in Hash table, and wherein R represents read write line identification number; O represents the identification code of product, i.e. EPC; T represents the reading time of label, carries out duplicate removal filtration and event filtering in Hash table; Namely duplicate removal is filtered is filter out the label repeated in certain hour section, exceeds the label that the time period repeats, then thinks new label, export this label and upgrade this tag reading time; If the label read did not occur, be inserted in Hash table, and export.Namely event filtering records label that is newly-increased and that leave, upgrades the tag reading time of data with existing.Data after filtration enter data buffering module, high-speed cache CACHE in data buffering module stores mass data temporarily, and information is passed to EPC system, EPC system can be inquired about the background of agricultural product and production information, then high-speed cache CACHE is fed back to, the feedback information received is carried out elementary event integration by high-speed cache CACHE, and the elementary event constantly produced forms flow of event, flow of event input server; The Complex event processing system of server according to receiving SASE query statement, be carried out real-time query or interesting event extraction to event, can also extract useful information stored in event database.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within all spirit in invention and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
