Pass back to positioning navigation module 3 after to navigation results in real time again, save the memory headroom of positioning navigation module 3.It is above-mentioned, that is, realize
Positioning and navigate.
Visible ray issue device 33 is also equipped with information loaded circuit, and positioning navigation module 3 passes through visible ray issue device
33 send the visible ray of carrying information, and the first visible optical pickup apparatus 22 is used to receiving that visible ray issue device 33 to send is loaded with
Obtained information, is sent to navigation server 1 by the visible ray of information afterwards, has been achieved in that from positioning navigation module 3 to leading
The one-way data transfer of boat server 1；Meanwhile, navigation server 1 sends the visible ray for being loaded with information on services by LED 21,
Second visible optical pickup apparatus 32 is used for the visible ray for receiving the carrying information that LED 21 is sent, and has been achieved in that from navigation clothes
Business device 1 arrives the one-way data transfer of positioning navigation module 3.Above-mentioned combination, that is, realize positioning navigation module 3 and navigation server
Bidirectional data transfers between 1.
Thus, by such scheme, a kind of Position Fixing Navigation System based on visible light communication of the present utility model has been realized
The function of positioning, navigation and data transfer.In existing visible ray location and navigation technology, even if its positioning function is to pass through
It can be seen that optical communication is realized, but its data transfer is realized by wireless networks such as GPS, WIFI, 2G, 3G or 4G, in portion
The confined place of wireless signal is divided to cause to carry out data transmission so that its online navigation feature is weakened, general
It can be navigated using offline map.And the function of positioning of the present utility model, navigation and data transfer can be by visible logical
News are completed, and above mentioned problem is solved well.
In the present embodiment, the detection means for detecting the current state of LED 21, detection means are provided with LED 21
It is connected with the communication of navigation server 1, detection means detects the state of LED 21 and testing result is sent in real time navigation in real time
Server 1.Preferably, detection means is used for the luminous intensity for detecting LED 21, and the luminous intensity information of the LED 21
Navigation server 1 is sent to, navigation server 1 believes the coding that the luminous intensity information of the LED 21 is added to the LED 21
In breath, luminous intensity detection means is preferably provided in LED 21 and positioned at the side of LED chip, such as current LED 21
Luminous intensity only has the 80% of normal value, and the reduction of luminous intensity can make it that the second visible optical pickup apparatus 32 detects should
The luminous intensity that LED 21 is sent also is reduced, and this influences whether distance operation result, accordingly, it would be desirable to the luminous strong of the LED 21
Degree carry out in real time record, it is necessary to when be also sent in positioning navigation module 3, calculate apart from when call.Preferably, LED
Lamp 21 is provided with luminous intensity control device, and the luminous intensity control device can be the chip of control electric current intensity, pass through control
Current strength controls the luminous intensity of LED 21, and the chip of control electric current intensity electrically connects with LED 21；Luminous intensity control

Calculate.Preferably, detection means is additionally operable to detect whether the coding information of the relevant spatial positional information of LED 21 is correct, not
Corrected in time when correct, or whether detection LED 21 is damaged, and such as detects the luminous intensity of LED 21 and sets threshold value, works as inspection
The luminous intensity measured be less than the threshold value when, draw LED etc. 21 damage, detect LED 21 damage when and alarm.
In the present embodiment, by netting twine, USB data line or power line group is obtained between LED 21 and navigation server 1
Net any one of the power line of support mode and communicate connection, meanwhile, the first visible optical pickup apparatus 22 and navigation server 1
Between by netting twine, USB data line or obtain any one of the power line mode that power line networking supports and communicate connection.This
Sample, does not produce radio radiation in space, is conducive to health.
In the present embodiment, in visible ray transmitting-receiving array, the light-emitting area of LED 21 and the first visible optical pickup apparatus 22
Visible light receiving surface towards same direction.When LED 21 sends the visible ray for being loaded with communication signal toward a direction,
Due to just straightline propagation, and the signal of visible optical communication will be switched off when light is blocked, it is therefore desirable to set first visible
The visible light receiving surface of optical pickup apparatus 22 is also launched and next carrying information towards the direction with receiving from the direction
Light, to reach both-way communication.Similarly, it is seen that the visible ray of the light-emitting area of light issue device 33 and the second visible optical pickup apparatus 32
Receiving plane is towards same direction.In use, above-mentioned both direction should be relative, to realize that bi-directional data is passed
It is defeated.
In the present embodiment, the information on services for being sent to positioning navigation module 3 from navigation server 1 includes but is not limited to lead
Navigate information on services, cartographic information and internet traffic；Information on services may include navigation Service, nearby have which kind of service to carry
For etc., cartographic information may include neighbouring landform and service provision point etc., and internet traffic allows user to be carried out with contact staff
Link up, the information that surfs the web etc..Meanwhile, the information that positioning navigation module 3 is sent by visible ray issue device 33 is included but not
It is limited to the current location information, service request information and internet traffic of the positioning navigation module 3.
In the present embodiment, in visible ray transmitting-receiving array, per only 1 LED 21 in adjacent N number of LED 21 with
The communication connection of navigation server 1,1 the first visible optical pickup apparatus 22 is set at interval of M LED 21；It is as shown in Figure 1 every
Only have 1 LED 21 to be connected with the communication of navigation server 1 in 2 adjacent LEDs 21,1 is set at interval of 2 LEDs 21
First visible optical pickup apparatus 22.In actual applications, because the need for for positioning, the light of multiple LEDs 21 is needed
The place of reirradiation, but the place of reirradiation is it is not absolutely required to during for data transfer, as long as light can irradiate
To i.e. achievable data transfer, therefore, it is not necessary to each LED 21 is connected with the communication of navigation server 1, the first visible light-receiving
Device 22 also need not set excessively intensive, so advantageously reduce cost, and the visible ray of LED 21 and first specifically set connects
Depending on the density of receiving apparatus 22 can be according to actual conditions, as long as so that signal is not turned off in data transfer.
Finally it should be noted that：Above-described each embodiment is merely to illustrate the technical solution of the utility model, rather than
It is limited；Although the utility model is described in detail with reference to the foregoing embodiments, one of ordinary skill in the art
It should be understood that：It can still modify to the technical scheme described in previous embodiment, or to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or substitutions, the essence of appropriate technical solution is departed from the utility model
The scope of each embodiment technical scheme.
