Embodiment
For making object of the present invention, technical scheme, advantage clearly understand, below in conjunction with illustrative examples, and with reference to accompanying drawing, the present invention is described in more detail.It should be noted that the feature in the present invention in embodiment and embodiment can combine mutually when not conflicting.
The idle parking stall measure in parking garage based on optical communication provided by the invention and guidance system and method, realize based on LED illumination light source.LED light source is as a kind of energy-conservation, radiationless novel green lighting source, become the preferred light source of Lighting Design, upgrading, transformation, along with incandescent lamp is withdrawn from the market gradually, and LED light source has higher efficiency than electricity-saving lamp, the principal light source of parking lot illuminating engineering will be become, and LED have good can modularity, be easy to realize visible ray recognition coding (VisibleLightIdentification, VLID) technology, thus make indoor parking stall measure and personnel positioning become possibility.
As shown in Figure 1, one embodiment of the present of invention provide a kind of intelligent parking position based on optical communication to detect and guidance method, comprise LED light source 1, parking stall 2, has parked cars 3, corner reflector 4, driver 5(carries mobile terminal), 6(driver to be parked cars carries mobile terminal).In this bright embodiment, the LED light source 1 near parking stall sends light modulated, and each LED light source has unique 64 bits of encoded ID for determining the geographic position of light source, and wherein first group of 8 bit represents the provincial information in geographic position, supports 256 provinces at most; Second group of 8 bit represents urban information, and support 256 cities at most, the 3rd group of 4 bits represent district information, and support 16 districts at most, the 4th group of 12 bits represent building information belonging to intelligent parking lot, supports 4096 buildingss at most; 5th group of 4 bits represent the floor information in affiliated parking lot, support 16 layers at most; 6th group of 20 bit represent the planimetric coordinates information in same layer, and the 7th group of 4 bits are used for data check, wherein the coordinate information of the 6th group of 20 bits and parking stall 1 preset coordinate (X
n, Y
n) one_to_one corresponding.LED light source 1 coordinates with corner reflector 4, can measure whether whether parking stall 2 parked vehicle 3 i.e. parking stall idle, and is shown by the map system of mobile terminal entrained by driver.One, when parking cars, wait to park cars 6 driver utilize the map system of entrained mobile terminal to select empty parking space, such as (X4, Y4), and generate direction or route guiding; 64 bits of encoded ID of described mobile terminal records storing cycle position LED light source are utilized after parking.Two, find car time (assuming that storing cycle is at X6, Y6), driver 5 utilizes mobile terminal period to obtain 64 bits of encoded ID of current LED light source, if this ID and pre-recorded storing cycle position ID is in same parking lot, system then reads pre-stored map coordinate mapping information thus obtains personnel positions coordinate (X0, and vehicle location (X6, Y6), and guide or route guiding to outgoing direction Y0).
LED lamp 1 in Fig. 1 can adopt but not limit the white LED light source with illumination functions.
Driver 5 in Fig. 1 or the wait entrained mobile terminal in 6 that parks cars can adopt the mobile device that photodiode is housed, or the mobile device of camera is housed, such as smart mobile phone.
A kind of parking space state detection method that one embodiment of the present of invention 1 provide as shown in Figures 2 and 3, comprises LED light source 1, parking stall 2, vehicle 3, corner reflector 4, detector 7, utilizing emitted light 8, reflected light 9, transmission optical fiber 10; When in the present embodiment, parking stall is idle, as shown in Figure 2, the light 8 that LED light source 1 sends is irradiated to and is arranged on the corner reflector 4 on parking stall 2, corner reflector is the reflecting body that each reflecting surface becomes an angle of 90 degrees, it is characterized in that incident light to be returned by incident reverse direction, therefore, when not having storing cycle, reflection ray 9 can be irradiated on detector 7.When in the present embodiment, parking stall takies, as shown in Figure 3, when parking stall 2 parks cars 3 time, corner reflector 4 can be blocked, and utilizing emitted light 8 is irradiated to vehicle enclosure or glass surface, and the reflected light 9 of generation or most of energy of transmitted light 10 can not be irradiated on detector 7.By the signal that contrast detector 7 receives in varied situations, the state of parking stall 2 can be judged.
Wherein LED light source 1 can adopt but not limit the white light source with illumination functions.Because each LED light source 1 has 64 bit unique encodings, each detector 7 judges the coded signal corresponding to self, therefore effectively can avoid the interference of adjacent signal.
An alternative embodiment of the invention 2, as shown in Figure 4 and Figure 5, comprises LED light source 1, parking stall 2, vehicle 3, detector 7, utilizing emitted light 8, reflected light 9, transmitted light 10; Compared with embodiment 1, this embodiment reduces corner reflector 4 and detector 7 is installed on parking stall.As shown in Figure 4 when not having vehicle 3 to park, emission of light 8 can be irradiated on detector 7.As shown in Figure 5, when parking stall 2 parks cars 3 time, detector 7 can be blocked, and utilizing emitted light 8 is irradiated to vehicle enclosure or glass surface, and reflected light 9 or the transmitted light 10 of generation can not be irradiated on detector 7.By the signal that contrast detector 7 receives in varied situations, the state of parking stall 2 can be judged.The present embodiment can reduce the installation of a corner reflector 4, but needs the extra power supply and the signal transmission line that increase detector 7.
As shown in Figure 6, the intelligent parking position that the invention provides based on optical communication detects and guiding process flow diagram, comprises the following steps:
Step 401: utilize LED light source to detect parking stall idle condition;
Step 402: parked cars by the map system guiding driver of mobile terminal;
Step 403: after driver parks cars, uses mobile terminal automatically to record current LED light source coded message, is designated as storing cycle positional information;
Step 404: driver leaves parking lot;
Step 405: driver gets back to parking lot,
Step 406: driver uses mobile terminal, obtains current LED light source coded message;
Step 407: system is according to this coded message, confirmation personnel present encoding and whether storing cycle is position encoded be in same buildings and parking lot floor, be, and read map its virtual borderlines relation is fed back to driver, otherwise provide information, and repeat step 406;
Step 408: the electronic compass utilizing mobile terminal, determine driver current towards;
Step 409: mobile terminal, according to vehicle position information and personnel location information, indicates to outgoing direction or route
Step 410: whether arrive du vehicule, as no repetition step 406; As no, be, enter next step
Step 411: turning-off mobile terminal, terminates to use
