Problems solved by technology

[0005] The purpose of the present invention is to provide a reader and its RO rule scheduling method to solve the problem that preemption will not occur if the previous RO rule with higher priority is still occupying the resources of the reader

Embodiment Construction

[0031] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0032] figure 2 It is a flowchart of an RO rule scheduling method for a reader according to an embodiment of the present invention, including the following steps:

[0033] Step S202, the reader creates RO rules;

[0034] Step S204, the reader dispatches RO rules to perform state transitions (such as image 3 shown), the states include sleep state, delete state, active state, ready state and execution state; among them,

[0035] When the RO rule is in the active state, the reader judges that the trigger condition of the RO rule has arrived, the RO rule does not have the preemption condition, and the resource of the reader is busy, then the reader schedules the RO rule to enter the ready state;

Abstract

A reader operation (RO) spec scheduling method and a reader thereof are disclosed. The method comprises: a reader establishes a RO spec (S202); the reader schedules the RO spec to proceed state transitions and the states include a Disabled state, a Deleted state, an InActive state, a Ready state and an Executing state; when the RO spec is in an InActive state, the reader judges that a triggering condition of the RO spec arrives, the RO spec does not have a preemptive condition and the resource of the reader is busy, then the reader schedules the RO spec to be in a Ready state; when the RO spec is in a Ready state, the reader judges that the resource is free, then the reader schedules the RO spec to be in an Executing state and executes the RO spec (S204). With such solution, it perfects the process method of the reader when rules are conflicted and makes the post-triggering RO spec not lose the execution opportunity.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a reader and an RO rule scheduling method thereof. Background technique [0002] The LLRP (Low Level Reader Protocol) protocol is an underlying reading protocol released in April 2007 by EPC global (Electronic Product Code global, EPCglobal is a neutral, non-profit standardization organization jointly established by EAN and UCC). Reader protocol, which provides the ability to control air interface operations and air interface protocol command parameters, and provides access to the underlying reader operations. [0003] In the LLRP protocol, a RO (reader operation) rule (ROSpec) is mainly used to control the operation of reader inventory and radio frequency monitoring, and it has four states: delete state, dormant state, active state and execution state. figure 1 It is the state transition diagram of the reader rule (ROSpec) based on the LLRP protocol of the related technology....
