Problems solved by technology

Time Division Multiple Access (TDMA) is a communication technology for sharing transmission media (usually in the radio field) or network, allowing multiple users to use the same frequency in different time slices (time slots), and time It is divided into periodic frames, and each frame is divided into several time slots to send signals

Embodiment Construction

[0077] The method for the locator to access the base station is: positioning system (see figure 1 ) contains at least two positioning base stations and at least one movable locator; all positioning base stations are networked in a cellular manner (see figure 2 ), with the positioning base station A1 as the center in each cell, m positioning beacons a1~am are fixedly distributed around the positioning base station A1, and these positioning beacons a1~am are subordinate to the positioning base station A1; each positioning base station supports 4 channels , and the frequencies of the channels supported by the positioning base stations in adjacent cells are different; the long-distance wireless communication method is used between the locator and the positioning base station, and the short-distance wireless communication method is used between the locator and the positioning beacon; the positioning The method of accessing the positioning base station by the device is as follows: ...

Abstract

The invention relates to a method of accessing a positioner into a base station and a communication method of the positioner with the base stations. The method specifically comprises the following steps: 1, each base station broadcasts a synchronization head outward in each channel; 2, the positioner takes the base station as the current base station, wherein the beacon with the strongest signal around belongs to the base station, and then a channel is selected randomly; 3, the positioner receives the synchronization head broadcasted by the base station to judge whether an idle time slot is available or not; if the idle time slot is not available, the step 5 is implemented; 4, the positioner is accessed to the base station, and the step 6 is implemented; 5, the positioner re-selects a different channel, the step 3 is implemented; 6, if the positioner cannot send data to the base station, the step 3 is implemented; if so, the data is sent; and 7, if the positioner does not have data tobe sent, the process is ended; if so, and the previous Q beacons with the strongest signals around the positioner belong to a new base station, the positioner is switched to the base station, the step3 is implemented, otherwise, the step 6 is implemented. The data size of communication of the base stations is increased, the utilization ratio of the base stations is improved and the data transmission speed among the positioners is increased.

Description

(1) Technical field: [0001] The invention relates to an access method and a communication method of a locator in a positioning system, in particular to a method for a locator to access a base station and a communication method with the base station. (two), background technology: [0002] In the field of positioning, the existing positioning technology and equipment can be divided into two types from the perspective of the positioning area: one is outdoor positioning technology, such as GPS positioning technology, Beidou positioning technology, etc., which can only achieve the goal (such as the person being positioned) Positioning in an outdoor and unobstructed environment has great limitations and cannot accurately locate the target; the other is indoor positioning technology, such as Bluetooth positioning technology, ZigBee positioning technology, UWB positioning technology, etc. Positioning in an occluded environment, but its positioning distance is relatively short. In a...
