Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the present invention is described in further detail.
The RF identification exchange method that the present embodiment provides comprises the following steps:
Rf subscriber terminal sends to add and accesses operation rules message (ADD_ACCESSSPEC) to read write line, this ADD_
ACCESSSPEC includes accessing operational attribute information, accesses operational attribute information and includes for indicating access operation (AO) work shape
The working status parameter of state, the working status parameter instruction AO duty in this example is state of activation；
After read write line receives ADD_ACCESSSPEC, add and access operation rules accordingly, and by the duty of AO
It is set to state of activation.
The most in this example, read write line reads and writes, lock, stop (or referred to as killing) etc. when accessing operation, and rf subscriber is eventually
A kind of state of information relevant for the AO that end issues, i.e. activates (ACTIVE) state, and read write line is upon receipt of rf subscriber
The interpolation that terminal issues accesses operation rules message, and the duty of AO is the most directly set to state of activation, and not as existing
There is LLRP agreement to be set to be not enabled on (DISABLE) state, therefore need not ENABLE_ACCESS message and it is activated,
The number of times of interacting message between rf subscriber terminal and read write line can be reduced, and then interaction flow therebetween can be simplified, carry
The efficiency that high system processes, and then substantially increase the satisfaction of Consumer's Experience.
In this example, after read write line receives ADD_ACCESSSPEC, the duty of AO is set to state of activation it
Before, also include ADD_ACCESSSPEC is accessed what the working status parameter of operational attribute information was verified, as checking is logical
Cross, just the duty accessing operation is set to state of activation, to read and write, to lock, to stop access operations such as (killing).
In this example, before rf subscriber terminal transmission ADD_ACCESSSPEC is to read write line, also include that sending interpolation reads
Read operation Rules Message (ADD_ROSPEC) gives read write line；After read write line receives ADD_ROSPEC, add and read behaviour accordingly
Make (RO) rule, and feed back interpolation reading operations rule response (ADD_ROSPEC_RESPONSE) give rf subscriber terminal, now
The duty of RO is for being not enabled on state, and activates the work shape of RO according to the concrete condition of rf subscriber terminal access read write line
State, specific as follows:
When rf subscriber terminal single reference read write line, after rf subscriber transmission ADD_ROSPEC is to read write line；Also
Reading operations message (ENABLE_ROSPEC) is enabled to read write line including sending；After read write line receives ENABLE_ROSPEC,
The duty of RO is set to unactivated state, and feeds back enable reading operations response (ENABLE_ROSPEC_RESPONSE)
To rf subscriber terminal；After rf subscriber terminal receives ENABLE_ROSPEC_RESPONSE, send activation reading operations and disappear
Breath (START_ROSPEC) gives read write line；After read write line receives START_ROSPEC, it is set to the duty of RO activate
State, and feed back activation reading operations respond to described rf subscriber terminal.
When the access read write line of rf subscriber terminal periodic, rf subscriber send ADD_ROSPEC to read write line it
After；Also include sending and enable reading operations message (ENABLE_ROSPEC) to read write line；Read write line receives ENABLE_
After ROSPEC, the duty of RO is set to state of activation, and feeds back enable reading operations response (ENABLE_ROSPEC_
RESPONSE) rf subscriber terminal is given.
In this example, the operational attribute information that accesses of ADD_ACCESSSPEC also includes the ID parameter accessing operation, accesses operation
Stop condition；After read write line receives ADD_ACCESSSPEC, also include accessing the parameter (example that operational attribute information includes
As accessed the ID parameter of operation, access the stop condition of operation) verify, as being verified, and above-mentioned working status parameter
Verify also by, then ADD_ACCESSSPEC operational attribute information is added in the storage queue accessing operation, and should
The call number of ADD_ACCESSSPEC operational attribute information or this ADD_ACCESSSPEC operational attribute information adds coupling team to
In row, feedback adds access operation rules success response to rf subscriber terminal.
When the stop condition accessing operation that ADD_ACCESSSPEC carries meets；Read write line will access the work of operation
State is set to halted state.
In this example, read write line receives the deletion access operation rules message (DELETE_ that rf subscriber terminal sends
ACCESSSPEC), after, the duty of AO is set to halted state.
Before rf subscriber terminal transmission interpolation access operation rules message is to read write line, also include that sending deletion reading advises
At the beginning of then message (DELETE_ROSPEC) and deletion access operation rules message (DELETE_ACCESSSPEC) are carried out to read write line
Beginning process, for by AO rule used during last visit and RO redundant rule elimination；Read write line receive DELETE_ROSPEC and
After DELETE_ACCESSSPEC, delete corresponding RO rule and AO rule, and feed back deletion reading rule response (DELETE_
ROSPEC_RESPONSE) access operation rules respond (DELETE_ACCESSSPEC_RESPONSE) to rf subscriber with deletion
Terminal.
This example additionally provides a kind of radio-frequency recognition system, including rf subscriber terminal and read write line, rf subscriber terminal
Realize RF identification with read write line as stated above and the most complete corresponding feature operation.Below in conjunction with concrete accompanying drawing to this
