Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, it is below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is described in further detail.
Embodiment one
With reference to Fig. 1, show that a kind of step flow chart of indoor navigation method provided in an embodiment of the present invention interior is led
Boat method can be applied to mobile terminal, specifically may include steps of：
Step 101：The first optical signal sent to the first light-emitting device parses, and determines first light-emitting device
First position information.
In embodiments of the present invention, mobile terminal can be mobile phone, tablet computer etc..First light-emitting device refers to have
The light-emitting device of communication function, the first light-emitting device can be LIFI light-emitting devices etc., such as LIFI lamps.In the first optical signal
In contain the location information of the first light-emitting device.
In places such as large supermarket, markets, multiple light-emitting devices, such as LIFI lamps can be set in these place overhead,
So that the optical signal of light-emitting device transmitting can cover each corner in these places.
When mobile terminal is in the coverage area of the first light-emitting device transmitting optical signal, then the first hair can be received
First optical signal of electro-optical device, in the optical signal for receiving the transmitting of the first light-emitting device, by being solved to the first optical signal
Analysis can get the first position information of the first light-emitting device.
In embodiments of the present invention, which can be believed as the position that mobile terminal is presently in
Breath.
In practical applications, other any light-emitting devices that can send optical signal can be applied to the embodiment of the present invention
In, the embodiment of the present invention does not limit this.
After the location information for determining the first light-emitting device, then 102 are entered step.
Step 102：Obtain the merchandise news of specified commodity.
In embodiments of the present invention, specified commodity can be obtained by the Quick Response Code in mobile scanning terminal commodity packaging
Merchandise news, for example, user can then be got specific using the bar shaped Quick Response Code on mobile phone scanning " Aloe Vera Gel " packing box
Merchandise news, such as the place of production, price.
Certainly, any one other mode that can obtain specified merchandise news can be applied to the embodiment of the present invention,
Such as user is manually entered merchandise news, and the embodiment of the present invention does not limit this.
After the merchandise news for obtaining specified commodity, then 103 are entered step.
Step 103：The first position information and the merchandise news are sent to cloud server.

Step 206：The first position information and the merchandise news are sent to cloud server.
Step 207：It receives by the cloud server according to the first position information and the merchandise location information meter
Obtained path planning.
In embodiments of the present invention, the embodiment of 205~step 207 of above-mentioned steps and a kind of step of above-described embodiment
The embodiment of 102-104 is similar, specifically, is referred to the executive mode of above-described embodiment one, the embodiment of the present invention is herein
It is not repeated here.
Step 208：Receive the second optical signal sent by the second light-emitting device.
During user's carrying mobile terminal goes to specified commodity position according to path planning, due to variant
The range of optical signal covering that light-emitting device is emitted is different, the optical signal that can be emitted by different light-emitting devices, so as to
Determine that mobile terminal is presently in position.
In above process, the specified application needs that the optical signal that light-emitting device is sent is received in mobile terminal are in
The state of unlatching, for example, the front camera or rear camera of mobile terminal are always in the state opened.In mobile terminal
When receiving the second optical signal sent by the second light-emitting device, then 209 are entered step.
Step 209：Second optical signal is parsed according to the specified application, determines that described second shines
The second position information of device.
The second optical signal of reception can be parsed using specified application, may thereby determine that the second luminous dress
Second position signal where putting.
Step 210：The second position information is sent to the cloud server.
Step 211：Receive the prompt message sent by the cloud server.
In embodiments of the present invention, prompt message can include the distance prompt of customer mobile terminal current distance destination
Information, such as " also having 10m or 6m apart from destination " or the prompting when customer mobile terminal deviates path planning
Information etc..
Second position information is sent to cloud server by mobile terminal, and cloud server sentences second position information
It is disconnected, to judge whether second position information is in the range of the threshold distance of path planning, and it is whole to movement according to judging result
End sends prompt message.
Preferably, above-mentioned steps 101 can include：
Sub-step S1：When the second position information is in the threshold distance range of the path planning, described in reception
The distance prompt information that cloud server is sent.
In embodiments of the present invention, when cloud server judges that second position information is in the threshold distance of path planning
During range, then such as there can be 10m apart from destination to the specific prompt message of mobile terminal transmission range merchandise location information
Or 6m etc..
Certainly, when second position information, which deviates path planning, exceeds threshold distance range, for example, the second light-emitting device is inclined
When reaching 5m or 6m from the second path planning, then cloud server can send the prompting letter for deviateing path planning to mobile terminal
Breath, for example, " you are presently in position not in the range of path planning " or " you currently walk anisotropy " etc. prompting message.
It is to be appreciated that above-mentioned cited example is merely to more fully understanding the technical solution of the embodiment of the present invention and arranging
The example of act, and not as the sole limitation to the embodiment of the present invention.
Indoor navigation method provided in an embodiment of the present invention, except being had with the indoor navigation method shown in embodiment one
