Background technique
Short distance, high precision wireless indoor positioning technologies are widely used in urban compact region and indoor enclosure space
It is general.Positioning signal is mainly emitted using positioning label in existing positioning system, the mode that locating base station receives positioning signal is come
Realize positioning.One locating periodically is divided into several localization time slots by positioning system, and is belonged to for the distribution of each positioning label
The localization time slot of oneself further includes controlling locating base station using isochronous controller and positioning the timing between label in positioning system
It is synchronous, so that localization time slot of each positioning label where oneself emits positioning signal, meanwhile, locating base station is also by reception
The positioning signal is determined from which positioning label, to carry out to the positioning label to localization time slot locating for positioning signal
Positioning.By distributing localization time slot to positioning label, and only one in each localization time slot positions in same bit space undetermined
Label emits positioning signal, and positioning signal is not necessarily to carry its information from which positioning label, and locating base station only need to be according to connecing
It can determine whether which positioning label it belongs between time receiving.
When each locating periodically starts, isochronous controller emits locating periodically initial signal, positioning mark to positioning label
Label start timing after receiving locating periodically initial signal, when timing is to localization time slot belonging to oneself, in oneself institute
Emit positioning signal in the localization time slot of category.But in the region that some signal interference intensity are larger or signal blocks are more serious,
Or due to positioning label own hardware, cause position label may holiday locating periodically initial signal, lead
It causes the positioning label in the locating periodically cannot respond to, so that positioning signal cannot be emitted, leads to not realize to positioning label
Positioning.
Therefore, how when missing locating periodically initial signal, positioning system can also be to positioning tag location for research
Scheme the problem of becoming this field researcher's urgent need to resolve.
