Embodiment
The present invention includes electronic label read/write, RFID router and network control unit, wherein, network control unit comprises server and switch.Read write line adapter and the read write line in addition that are connected with the RFID router.
As shown in Figure 1, RFID router of the present invention comprises CPU, internal memory, ICP/IP protocol modular converter (not shown), electronic label read/write interface (i.e. many serial interfaces among the figure) and network interface, internal memory, electronic label read/write interface and ICP/IP protocol modular converter are connected with CPU, and the ICP/IP protocol modular converter is connected with network interface; Network control unit specifically is connected with network interface, and electronic label read/write specifically is connected with the electronic label read/write interface.
After in a manner described each device being connected, the parameter information of the page configuration router by web.These parameter informations comprise, the numbering of configuration router, and ip address; Number and corresponding model that the configuration read write line inserts; Data transfer mode after the configuration image data comprises http, jms, soap etc.; Configuration reception incident and forwarding incident directly concern, comprise one to one one-to-many etc.; After configuration finishes, just can use.Can by the web page monitor each read write line operation conditions, allow that certain read write line is started working etc.And will cross data broadcasting that router transmits out to background server.
As shown in Figure 2, read write line adapter of the present invention carries out communication with read write line directly or indirectly, and collects the incident that read write line detects.Then these incidents are write the read write line adapter.Read write line only is responsible for recognition and the existing incident of transmission, does not possess and judges and memory function.For example, read write line can identify all labels in the recognition scope, but can't judge whether to misread or the skip label.As long as the label in the recognition zone is constant, plug-in reader just continues to send flow of event, identifies all labels that it is found.Except the time for reading of sign EPC and EPC, can also generate non-EPC information (as temperature, humidity etc.) and state event (tell upper system, a simple reader processing process is finished) in the logout.
The EPC incident is gathered in read write line adapter and read write line communication.It is the incident fabricator, to any " event consumer " transmission read write line incident that the read write line interface is arranged.Read write line can adopt multiple physics mode and computing machine to carry out communication (as Ethernet, Serial Port Line), perhaps adopt different communications protocol, in order to support different types of read write line, this router provides multiple read write line adaptor interface, wherein comprises the concrete execution details of the login read write line and the incident of acquisition.In the read write line adapter, incident is divided into EPC incident, non-EPC incident, state event so that in the upper system by appropriate processing.
Shown in Fig. 2,4, RFID router of the present invention also includes event filter, and incoming event stream is carried out filtration treatment, and to one or more outgoing event flow transmission incidents.It is classified to incident, only sends their interested incidents to other filtrators, register and application program.Filtrator can get up as the assembly one by one of block toy quilt, to obtain the incident of expectation.For example smoothing filter can with the combination of a product filtrator, the interested incident of antiburglary application program is separated.Available filtrator comprises a variety of, and this router provides three kinds of filtrators at present, but along with the increasing of application case, can provide increasing filtrator, these three kinds of filtrators: product filtrator, time filter and smoothing filter.The product filtrator can only send and the relevant product information of a certain product or manufacturer, and in other words, filtrator only sends the EPC data of a certain scope or mode.Time filter can come filter event according to time keeping, and for example, time filter may only send the incident in nearest 10 minutes.Smoothing filter is responsible for handling the situation that those are made mistakes, and comprises skip and misreads.So judging whether a label leaves before the recognition zone, and the data that read write line sends must be passed through filter process, otherwise can't judge whether this recognition makes mistakes.When the incident that sends a certain quantity when read write line all identifies certain tag readable degree failure, can assert that label has exceeded the recognition scope.For example, be 5 if set the limit number of recognition failure, when continuous 5 event identifier read write lines can't be distinguished certain label, assert that this label has exceeded the recognition zone.Different with event queue, event filter is synchronous applications normally.Event filter can be placed between incident fabricator and event consumer, and incident is carried out smoothly, coordinated and transmits.Because event queue is neither the incident fabricator neither the consumer, they are called incident forwarding person.
Event queue is an asynchronous queuing system, but adopts synchronization mechanism to handle multiple read write line logout.Queuing system can write down the incident of being read by multiple read write line adapter, and they are transferred in all read write line event recorders of registering in the system.When incident is made by read write line, after the digestion of read write line adapter, just be sent in the event queue.In event queue, incident is sent in filtrator or the register, and according to the difference of filter definition, different incidents is filtered or notes.Login or cancellation that event recorder is can be in event queue real-time.
It is basic system that queuing system adopts message-oriented middleware, increases the handling capacity that a plurality of message channels increase system on this basis.For example, a database event recorder may be used in most times in the disk read and write, but can not slow down the speed to the network event register of remote server transmission real-time event.Because event queue is not neither the incident fabricator is an event consumer again, they are called event transmission person.As shown in Figure 3, the invention describes the asynchronous event queue system.At the pointer place of inlet flow, be added in the round-robin queue from the incident of input queue, when arriving the formation end, pointer returns queue heads.
As Fig. 2, event router of the present invention is not except to other filtrators and transponder transmission incident, and transponder is identical with filtrator in itself.Event router is supported the multiple method of operation of read write line interface, allows incident is carried out various processing.For example, an application of read write line interface can be with information storage in database, and Another application then is placed on information in the store data structure, and Another application can be broadcast to distant place server by HTFP, JMS or soap protocol with incident simultaneously.Event recorder also is called " event consumer ", because the incoming event in their consumption flows of event.Above processing unit is organized into DAG when EMS system start-up, have only its all annexes all to start after, EMS could start certain processing unit.The configuration file of EMS has defined this DAG.During startup, " EMS construction solution parser " loads this file, starts processing unit according to file specification then.
As shown in Figure 5, the assembly that also comprises of the present invention has: task manager, SOAP interface, class server and database.Wherein, task manager is responsible for moving and safeguard the task in the router, and these Charge-de-Mission users move in router.All tasks all are subordinated to the timetable in the system, and this voting is decided task and how long moved once, whether should continue operation or the like.Rely on this timetable, task manager could determine which task should be carried out in each time step.Introduce requirement how to satisfy task manager below, the timetable arrangement relevant with task according to task type, the following action of task manager: for disposable task, if request is disposable inquiry, task manager is just handled query task and return results; For cycle task, if contain " table cycling time " in the request, task manager deposits timetable in " persistent storage ", and regulation is executed the task as per the schedule then; For permanent task, if request is the permanent task that continues execution, the regular monitor task of task manager.When wrong the appearance, task manager just restarts this task.
The SOAP server is responsible for showing the function and the interface of task manager, and it becomes task manager and can be served by the SOAP that all systematic unities are visited.Comprise the easy configuration descriptor document that task manager is explained detailed way by submission, can obtain interface configuration, along with the expansion of the maturation of task manager and its API, can be by increasing the new statement way descriptor of upgrading.
For system task can dynamically be added, in case new class can be used, task manager is with regard to the new class of sense(-)class downloaded about demand.This can be easy to realize upgrading, new task interpolation and modification in system, and need not to restart.
Database provides persistent storage for task manager.The task of submission and the details of task scheduler have been preserved in the database.Therefore, the oriented system task of submitting to all can stay the fragment of task manager.Relative recording is also upgraded in each circulation, task manager all query task database in view of the above.
