This invention puts forward a software and hardware module to manage the RFID reader applying SNMP and a standard plan for designing the MIB.
Description
Technical field
The present invention relates to the solution of using the SNMP NMP that rfid interrogator is managed, particularly to carry out the solution of real-time management by the rfid interrogator of PC access network, the present invention will propose module of software and hardware standard that it is managed, and the standard scheme of management information bank (MIB) design.
Background technology
RFID (Radio Frequency Identification) technology is a kind of automatic identification technology that rises the nineties in 20th century, and rfid system has obtained using widely in a lot of fields with its outstanding advantage.Internet of Things based on the RFID technology forms.A most critical in this network partly is exactly a rfid interrogator, and read write line often is installed in different zones as acquisition terminal, for example by avenue roadside, the highway, even some deathtraps.The automatic monitoring how by network the operating state of read write line to be carried out real-time high-efficiency is the important need that use in current RFID field, the present international and domestic standard that also read write line is not managed, each producer is not integrated into read write line inside with the module of network enabled management yet.Therefore it is necessary formulating unified read write line management regulation.
SNMP (Simple Network Management Protocol) agreement is a kind of management agreement that present computer network generally uses, it is a kind of NMP based on TCP/IP, mainly comprise parts such as management station, administration agent, management information bank and management agreement.It provides standard set management information bank and management agreement for computer network management, referring to Fig. 1.By the management information bank of expansion snmp protocol, snmp protocol can be applied to the management domain of rfid interrogator.
Summary of the invention
The objective of the invention is to: by the management information bank of expansion snmp protocol, snmp protocol is applied to the network management of rfid interrogator, provides a kind of carry out the solution of real-time management by the rfid interrogator of PC access network.
Technical scheme of the present invention is: a kind of by expansion snmp protocol management information bank, use snmp protocol, rfid interrogator is carried out the solution of network management, at present, the rfid interrogator majority passes through serial port, USB interface and TCP/IP interface link to each other with PC and carry out information exchange, then by the PC access network.The present invention is primarily aimed at rfid interrogator by the PC access network and has proposed a kind of it to be carried out the solution of real-time management, it is made up of several parts such as read write line information management module on the agency of the snmp management on the PC, rfid interrogator MIB storehouse, application program and the read write line, and this scheme also comprises the standard scheme of a rfid interrogator management information bank (MIB) design.
Advantage of the present invention is: the management information bank of having expanded snmp protocol at the characteristics of rfid interrogator and RFID network application, the standard scheme of one cover software and hardware solution and RFID management information bank has been proposed, for the SNMP application of different manufacturers exploitation rfid interrogator is provided convenience.

Embodiment
Below the present invention is done and describe in further detail.Referring to Fig. 2, the invention provides a kind of to carry out the solution of real-time management by the rfid interrogator of PC access network.Rfid interrogator links to each other with PC by serial port, USB interface or TCP/IP interface, by the PC access network, the snmp management factorage with PC that rfid interrogator is connected in, being embedded into read write line information management module in the read write line is used for collecting and needs monitored information in the read write line, pass to the RFID application program and the monitoring program of PC then, RFID application program and monitor call mib information are revised interface and are revised corresponding mib information.Management station by sending the SNMP message mode and the administration agent exchange message checking and to set read write line MIB storehouse on the PC, or accept the warning information of administration agent, finish management to read write line.
The hardware of this scheme realizes in two kinds of situation, the one, and the main control unit that adopts rfid interrogator is done like this and can be reduced cost as the read write line information management module, but when main control unit can't operate as normal, can't obtain the in-depth monitoring information of read write line; Another kind method is to adopt independently read write line information management module, and utilizing independently, battery and power supply carry out dual power supply.Read write line information management module and rfid interrogator main control unit adopt serial communication protocol to obtain a part of state information, take independently supervisory circuit to obtain most information.The read write line information management module is by serial port, and TCP/IP or USB mouth link to each other with PC.
Application program on the PC comprises RFID application program and two parts of monitoring program, collects the state information of RFID application program on the job information of read write line and the PC respectively.For second kind of hardware plan, mainly adopt monitoring program to collect RFID application state information on the information of read write line and the PC, revise in the MIB storehouse table accordingly according to the information of collecting.
Application program on the PC and read write line manage the communication protocol of information exchange:
1) PC is to the query statement of read write line: " SNMP "+" OID " (object identity)
2) read write line is to the inquiry response of PC: " SNMP "+" OID "+mib information rfid interrogator MIB design, and referring to Fig. 3.According to the actual needs of read write line monitoring, that the monitored information classification of read write line part is as follows:
1. read write line information sets, operating voltage for example, working temperature, tranmitting frequency etc.
2. reader/writer module group, high-frequency model operating state for example, main control module operating state, communication module operating state etc.Wherein,
● the high-frequency model work state information comprises operating voltage, high frequency amplifying module, modulation module, coding/decoding module etc.
● the main control module work state information comprises operating voltage, master control circulation, command status, operating state etc.
● the communication module work state information comprises operating voltage, communication type, transmitting-receiving byte number, traffic rate, reiving/transmitting state etc.

The MIB query scheme:
Object in the MIB storehouse is divided into two kinds, real-time object and non real-time sex object.The real-time object is meant those time dependent dynamic datas (as temperature etc.); The non real-time sex object refers to those time-independent static datas (as frequency etc.).For the real-time object,, read or be provided with relevant information on the hardware by the RFID application program when inquiry during this object; For the non real-time sex object, in internal memory, keep a static variable value, this quiescent value is carried out initialize when system initialization.If reading this object value does not then need to read hardware information, it is just much of that only to return this static variable value.If this object is set, must relevant information on the hardware be set by the read write line application program, change the static variable value simultaneously, in order to reading later on.
MIB warning scheme:
When the operating state of a certain object properties of management and monitoring surpasses preset threshold or unexpected phenomenon occurs, surpass the greatest measure of setting as a certain module operating voltage or working temperature; Master control circulation in the main control module endless loop occurs or restarts phenomenon or the like.The agency according to the object properties information in the Trap bag, reports corresponding fortuitous event by sending a Trap warning information to management station so.
