Abstract
Description
Technical field
The invention belongs to the positioning via network method of wireless communication technology field, more particularly to bluetooth equipment.
Background technology
With the development of Internet of Things, low-power consumption BLE is increasingly subject to city as a kind of wireless near field communication solution The attention of field.Low-power consumption BLE segments market in wireless accessory or the new of wireless product, including personal health and health care facility, The application in the field such as advertisement, indoor positioning and adjacent tags trend into like a raging fire.
How using BLE technologies to realize that indoor positioning is oriented to, how to know the distribution situation of BLE equipment in region, into For one it is increasingly urgent the problem of.
Patent application 201611189929.9 discloses a kind of mesh network-building methods based on BLE attributes and GATT, including Several BLE equipment, the BLE equipment include GATT, and mesh clothes are added by way of increasing mesh layers newly on the GATT Business, the mesh services meet GATT protocol rules, its step includes：Open networking；Build level-one path；Build second grade highway Footpath；Networking is completed.The present invention it goes without doing it is any setting and change can directly by existing BLE equipment access mesh networks, Realize the mesh networks of BLE so that the equipment more than Bluetooth RF distance can be by way of other bluetooth equipments relay Realize communication interaction, by mesh networks, user can control substantial amounts of BLE equipment at the same time by an access point.However, should Patent application is to carry out networking, although solving the problems, such as networking, this mode using GATT agreement combination mesh networks Networking efficiency is low, and data transfer is slow, it is difficult to meets the needs of real-time positioning and guiding.
The content of the invention
Based on this, therefore the present invention primary mesh be to provide a kind of indoor positioning guidance method using BLE mesh, This method can use the small-sized BLE nodes with bluetooth mesh networking functions to carry out networking, form positioning and guiding grid system, It can access BLE mesh networks with the BLE equipment in the range of scanning area and forming position information database, mobile equipment and obtain Obtain the guiding positional information of positioning position information or BLE equipment.
It is to provide a kind of indoor positioning guidance method using BLE mesh, this method carries another mesh of the present invention The network formed for BLE nodes, can quickly and accurately transmit data, positioning is in time, accurately, reliably.
To achieve the above object, the technical scheme is that：
A kind of indoor positioning guidance method using BLE mesh, it is characterised in that this method uses and carries bluetooth mesh groups The BLE nodes of net function carry out networking, form positioning and guiding grid system, can be with the BLE equipment in the range of scanning area and shape Into location information data storehouse, mobile equipment can access the guiding that BLE mesh networks obtain positioning position information or BLE equipment Positional information.
Further, realization of the invention includes the following steps：
101st, system includes a certain number of BLE nodes, is layouted according to indoor concrete condition, the shape on solid space Into latticed distribution, the corresponding positional information of each BLE node bindings；
Each BLE nodes can be carried out positioning for BLE equipment in grid coverage region and be led by BLE mesh networkings To；BLE nodes can be realized by small-sized BLE nodes, in order to realize networking.
Can be by broadcast relay positional information, so as to cover whole grid regions by the small-sized BLE nodes after mesh networkings The positioning and guiding of BLE equipment in domain.
102nd, mobile equipment access BLE mesh networks, the positional information bound by adjacent small-sized BLE node broadcasts, from And realize the positioning of mobile equipment；
103rd, the broadcast message of the respective BLE equipment in scope of each small-sized BLE node scans, by identification equipment name or Physical address is screened；
104th, each BLE nodes obtain the broadcast message of the BLE equipment after screening, and the BLE equipment to respective scope is given birth to Into corresponding positional information, and pass through the positional information of broadcast relay shared BLE equipment in whole net region；
105th, system facilitates subsequent query according to the positional information forming position information database for the BLE equipment being collected into.
Further, mobile equipment can access BLE mesh networks, access the position letter that database obtains BLE equipment in region Breath, would know that the distribution situation of BLE equipment in region, so as to fulfill guide function.
The present invention carries out networking using the small-sized BLE nodes with bluetooth mesh networking functions, forms positioning and guiding grid System, can access BLE mesh nets with the BLE equipment in the range of scanning area and forming position information database, mobile equipment Network obtains the guiding positional information of positioning position information or BLE equipment.
Brief description of the drawings
Fig. 1 is the process chart that the present invention is implemented.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.
Shown in Fig. 1, for the indoor positioning guidance method using BLE mesh of the invention realized, this method use carries The BLE nodes of bluetooth mesh networking functions carry out networking, form positioning and guiding grid system, can be with scanning area in the range of BLE equipment and forming position information database, mobile equipment can access BLE mesh networks and obtains positioning position information or BLE The guiding positional information of equipment.
Specifically, this method comprises the following steps：
Step 1, layout BLE nodes according to indoor concrete condition, and latticed distribution is formed on solid space, The corresponding positional information of each BLE node bindings.
Step 2, each BLE nodes can be directed to BLE equipment in grid coverage region and be determined by BLE mesh networkings Position is oriented to.
Step 3, mobile equipment access BLE mesh networks, the positional information bound by adjacent small-sized BLE node broadcasts, So as to fulfill the positioning of mobile equipment.
The broadcast message of the respective BLE equipment in scope of step 4, each BLE node scans, passes through identification equipment name or thing Screened reason address.
Step 5, each BLE nodes obtain the broadcast message of the BLE equipment after screening, the BLE equipment to respective scope Corresponding positional information is generated, and shares the positional information of BLE equipment in whole net region by broadcast relay.
Step 6, system are conveniently subsequently looked into according to the positional information forming position information database for the BLE equipment being collected into Ask.
Mobile equipment can access BLE mesh networks, access the position that location information data storehouse obtains BLE equipment in region Information, would know that the distribution situation of BLE equipment in region, so as to fulfill guide function.
Therefore, the present invention carries out networking using the small-sized BLE nodes with bluetooth mesh networking functions, forms positioning and guiding Grid system, can access BLE with the BLE equipment in the range of scanning area and forming position information database, mobile equipment Mesh networks obtain the guiding positional information of positioning position information or BLE equipment.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
