Detailed Description

Class Definition CC1G2SingulationControl for LLRP parameter C1G2SingulationControl.

• Document Reference LLRP Specification Section 15.2.1.2.1.3

• Document Reference LLRP Specification Section 16.3.1.2.1.3

This C1G2SingulationControl Parameter provides controls particular to the singulation process in the C1G2 air protocol. The singulation process is started using a Query command in the C1G2 protocol. The Query command describes the session number, tag state, the start Q value to use, and the RF link parameters. The RF link parameters are specified using the C1G2RFControl Parameter (see section 15.2.1.2.1.2). This Singulation Parameter specifies the session, tag state and description of the target singulation environment. The following attributes are specified to provide guidance to the Reader for the singulation algorithm:

• Tag transit time: This is the measure of expected tag mobility in the field of view of the antenna where this inventory operation is getting executed.

• Tag population: This is the expected tag population in the field of view of the antenna.

In addition, the Singulation Parameter allows setting of the following:

• Session ID: This is the C1G2 session number that the tags use to update the inventory state upon successful singulation.

• TagInventoryStateAwareSingulationAction: This is used if the TagInventoryStateAware flag is set to true in the InventoryParameterSpec.

  • I: This is the inventoried state of the target tag population in the selected session. Only tags that match the session state participate in the inventory round. If the Ignore value is specified, the Reader ignores this field, and its up to the Reader implementation to determine the value of I used in the inventory round.

  • S: This is the state of the SL flag in the tag. Only tags that match that tag state participate in the inventory round. If the Ignore value is specified, the Reader ignores this field, and its up to the Reader implementation to determine the value of S used in the inventory round.

If a reader sets CanDoTagInventoryStateAwareSingulation to False in LLRPCapabilities (section 9.2.2), it SHALL ignore the TagInventoryStateAwareSingulationAction field.

Member Function Documentation

void LLRP::CC1G2SingulationControl::assimilateSubParameters (  CErrorDetails *  pError  )  [virtual]

Assimilates the decoded sub-parameters into m_listAllSubParameters. After fields are decoded, the CDecoder itself takes care of gathering the subparameters into m_listAllSubParameters. Once the end of the enclosing TLV (or message) is reached this assimilateSubParameters() function is called to create parameter refrences from the primary member variables. Parameters: [out]  pError  Error details for encoded stream Implements LLRP::CElement.

void LLRP::CC1G2SingulationControl::decodeFields (  CDecoderStream *  pDecoderStream  )  [virtual]

Virtual function provided by each specific element type to decode fields (simple values). Leaves pDecoderStream at first subparameter. Parameters: [in]  pDecoderStream  The stream from which to decode fields Returns: void Implements LLRP::CElement.

void LLRP::CC1G2SingulationControl::encode (  CEncoderStream *  pEncoderStream  )  const [virtual]

Encode fields and subparameters. Parameters: [in]  pEncoderStream  Stream to encode Returns: void Implements LLRP::CElement.
