in this example namely, read write line is read, write, lock, when stopping accessing operations such as (or be called kill), the information that the AO that the rf subscriber terminal issues is relevant only has a kind of state, namely activate (ACTIVE) state, in a single day read write line receives the interpolation accessing operation rule message that the rf subscriber terminal issues, just directly the duty of AO is set to state of activation, and be not that the existing LLRP agreement of picture is set to not enable (DISABLE) state, therefore do not need ENABLE_ACCESS message that it is activated, can reduce the number of times of interacting message between rf subscriber terminal and read write line, and then the interaction flow between can simplifying both, improved the efficient that system processes, and then greatly improved the satisfaction that the user experiences.
In this example, after read write line receives ADD_ACCESSSPEC, before the duty of AO is set to state of activation, also comprise the working status parameter of the accessing operation attribute information of ADD_ACCESSSPEC verified, as be verified, just the duty of accessing operation is set to state of activation, to carry out reading and writing, to lock, stop accessing operations such as (killing).
In this example, the rf subscriber terminal sends ADD_ACCESSSPEC to before read write line, also comprises sending to add reading working rule message (ADD_ROSPEC) to read write line; After read write line receives ADD_ROSPEC, add corresponding operation (RO) rule of reading, and feedback is added reading working rule response (ADD_ROSPEC_RESPONSE) to the rf subscriber terminal, this moment, the duty of RO was enabled state not, and activate the duty of RO according to the concrete condition of rf subscriber terminal access read write line, specific as follows:
When rf subscriber terminal single reference read write line, rf subscriber sends ADD_ROSPEC to after read write line; Also comprise sending and enable to read operation information (ENABLE_ROSPEC) to read write line; After read write line received ENABLE_ROSPEC, the duty of RO was set to unactivated state, and feedback enables to read operation response (ENABLE_ROSPEC_RESPONSE) to the rf subscriber terminal; After the rf subscriber terminal receives ENABLE_ROSPEC_RESPONSE, send to activate and read operation information (START_ROSPEC) to read write line; After read write line received START_ROSPEC, the duty of RO was set to state of activation, and feedback activates reading operation response to described rf subscriber terminal.
When the access read write line of rf subscriber terminal periodic, rf subscriber sends ADD_ROSPEC to after read write line; Also comprise sending and enable to read operation information (ENABLE_ROSPEC) to read write line; After read write line received ENABLE_ROSPEC, the duty of RO was set to state of activation, and feedback enables to read operation response (ENABLE_ROSPEC_RESPONSE) to the rf subscriber terminal.
In this example, the accessing operation attribute information of ADD_ACCESSSPEC also comprises the ID parameter of accessing operation, the stop condition of accessing operation; after read write line receives ADD_ACCESSSPEC, also comprise parameter that the accessing operation attribute information is comprised (the ID parameter of accessing operation for example, the stop condition of accessing operation) verify, as be verified, and above-mentioned working status parameter checking is also passed through, ADD_ACCESSSPEC operational attribute information is added in the storage queue of accessing operation, and the call number of this ADD_ACCESSSPEC operational attribute information or this ADD_ACCESSSPEC operational attribute information is added in the coupling formation, feedback is added the success response of accessing operation rule to the rf subscriber terminal.
When the stop condition of the accessing operation that carries at ADD_ACCESSSPEC satisfies; The duty of read write line accessing operation is set to halted state.
In this example, after read write line received the deletion accessing operation rule message (DELETE_ACCESSSPEC) of rf subscriber terminal transmission, the duty of AO was set to halted state.
The rf subscriber terminal sends adds accessing operation rule message to before read write line, also comprise sending that regular message (DELETE_ROSPEC) is read in deletion and deletion accessing operation rule message (DELETE_ACCESSSPEC) is carried out initialization procedure to read write line the regular and RO redundant rule elimination of AO used when being used for last visit; After read write line receives DELETE_ROSPEC and DELETE_ACCESSSPEC, delete corresponding RO rule and AO rule, and feed back deletion and read rule response (DELETE_ROSPEC_RESPONSE) and delete accessing operation rule response (DELETE_ACCESSSPEC_RESPONSE) to the rf subscriber terminal.
A kind of radio-frequency recognition system also is provided in this example, has comprised rf subscriber terminal and read write line, rf subscriber terminal and read write line realize that as stated above radio-frequency (RF) identification completed corresponding feature operation alternately.The present invention will be further described below in conjunction with concrete accompanying drawing.
