In some embodiments, the information distribution module includes a distribution sub-module and a light source driving module corresponding to each light source. The step 801 is implemented by an allocation submodule, that is, the allocation submodule allocates the data information from the information receiving module to each light source driving module by adopting a method based on position coding; the step 802 may be implemented by a light source driving module, that is, the light source driving module generates a driving current according to the data information from the sub-module, and drives each light source to emit a light signal containing the corresponding data information.
The step 203 may be implemented by an information receiving device, which may be a mobile terminal, such as a mobile phone, iPad, etc., held by a visitor visiting the museum. In specific implementation, the receiving device receives the optical signals sent by each light source, converts the optical signals into corresponding data information, and combines the data information corresponding to each light source into complete data information by adopting a position coding-based method.
The information receiving apparatus has a structure as shown in fig. 4, and includes a light receiving module, an information converting module, and a decoding module. In the implementation, the light receiving module receives the light signals containing the data information sent by the light sources and transmits the light signals to the information conversion module; the information conversion module receives the optical signal from the optical receiving module, converts the optical signal into corresponding data information and transmits the data information to the decoding module; the decoding module receives the data information from the information conversion module and combines the data information corresponding to each light source into complete data information by adopting a position coding-based method.
The position coding-based method in the above step specifically sets the weight of each light source in data transmission according to the relative positional relationship between at least two light sources and the reference object, so that the at least two light sources transmit the corresponding data information according to the set weight. As shown in fig. 5, the picture in the booth corresponds to data information, which is a string of binary bit streams, which needs to be transmitted to the tourist's handheld terminal through three LED lamps as shown in fig. 1. According to the embodiment, different weights are distributed to the three LED lamps, so that the three LED lamps can simultaneously send bit streams corresponding to the picture name, the author and the creation time in fig. 5, and the transmission efficiency of data information can be improved.

As shown in fig. 1, a picture is provided on a wall of a booth; the ceiling of the booth has three LED lamps: LED1, LED2, LED3; high-speed bright-dark flickering signals which cannot be seen by naked eyes and can be emitted by the LEDs 1,2 and 3; the remote server (not shown) stores the related data information of the picture, including picture name, author and creation time, and the data information exists in the remote server in the form of binary bit data, as shown in fig. 5, the binary bit data includes N bits, the upper N1 bit is the picture name, the middle N2 bit is the author, and the lower N3 bit is the creation time, wherein, the specific length of n1+n2+n3=n, N, N1, N2, N3 can be determined according to the information amount to be transmitted; the tourist holds the mobile phone (namely the information receiving device) to shoot the picture on the wall.
In the implementation, the remote server sends the drawn data information to an information receiving module of the information sending device shown in fig. 3 through a wireless network in the form of a binary bit stream; after the information receiving module receives the data information from the remote server, the data information is sent to the distribution sub-module; the allocation submodule divides the N-bit binary bit data into a high N1 bit, a middle N2 bit and a low N3 bit, allocates the high N1 bit to the light source driving module corresponding to the LED1, allocates the middle N2 bit to the light source driving Mo Kui corresponding to the LED2, and allocates the low N3 bit to the light source driving module corresponding to the LED3; each light source driving module generates corresponding driving current according to the received data information, and drives each light source to emit high-speed bright-dark flickering signals which contain the corresponding data information and cannot be seen by the naked eye; when a tourist holds a mobile phone to photograph the picture, a camera (namely a light receiving module) can capture the high-speed bright-dark flickering light signals and transmit the light signals to an information conversion module; the information conversion module converts the received optical signals into corresponding binary bit data and transmits the binary bit data to the decoding module; the decoding module combines the received data information from different light sources by adopting a position coding-based method to obtain complete data information, namely, putting binary bit data corresponding to the LED1 in the high position of the complete binary bit data, putting binary bit data corresponding to the LED2 in the middle position of the complete binary bit data, putting binary bit data corresponding to the LED3 in the low position of the complete binary bit data to obtain the complete binary bit data, and then converting the complete binary bit data into the complete data information, namely, the picture name, the author and the creation time of the picture.
The specific embodiment of the position coding-based method disclosed by the application is that the high N1 bit is allocated to the light source driving module corresponding to the LED1, the middle N2 bit is allocated to the light source driving module corresponding to the LED2, and the low N3 bit is allocated to the light source driving module corresponding to the LED 3. As shown in fig. 1, there is a door in the booth, in this embodiment, the door is used as a reference, and different weights (for example, different positions in the whole binary bit data stream are allocated to the three LED lamps and the door) are allocated to each lamp by using the relative distance between the door and the door, where the LED1 is farthest from the door, and the high bit is allocated to the LED1, and the weight is N1, that is, the high N1 bit in the whole binary bit data stream is allocated to the LED 1; the second distance from the LED2 to the gate, the middle bit is allocated to the LED2, and the weight is N2, namely the middle N2 bit in the whole binary bit data stream is allocated to the LED 1; the LED3 is closest to the gate, and the low order is allocated to the LED3, and the weight is N3, that is, the low N3 bits in the entire binary bit data stream are allocated to the LED 3. Of course, the lower N3 bits may be allocated to the LED1, and the higher N1 bits may be allocated to the LED3, which is not limited herein.
That is, the high-to-low weight of each light source in data transmission may be set in the order of the light source and the reference object from the small to the large, or the high-to-low weight of each light source in data transmission may be set in the order of the light source and the reference object from the large to the small.
Of course, other embodiments of the position-coding based method are also possible. As shown in fig. 6, three LED lamps are arranged on a wall of a booth, in this embodiment, the picture itself is taken as a reference, and different weights are allocated to the lamps according to the relative heights between the three LED lamps and the picture, wherein the relative height between the LED1 and the picture is highest, the LED1 is allocated with a high bit, and the weight is N1, namely the LED1 is allocated with a high bit N1 in the whole binary bit data stream; the relative height of the LED2 and the picture is the second highest, a median bit is allocated for the LED2, and the weight is N2, namely, the median N2 bit in the whole binary bit data stream is allocated for the LED 1; the relative height of the LED3 and the picture is the lowest, the LED3 is allocated with low order, the weight is N3, namely the LED3 is allocated with low order N3 in the whole binary bit data stream.
Of course, other embodiments of the position-coding based method are also possible. As shown in fig. 7, three LEDs are also disposed on the wall of the booth, in this embodiment, the picture itself is also taken as a reference, the picture is taken as an origin, and different weights are allocated to the lamps according to the relative angles between the three LED lamps and the origin, wherein the relative angle between the LED1 and the picture is the smallest, the LED1 is allocated with a high position, and the weight is N1, that is, the LED1 is allocated with a high N1 position in the whole binary bit data stream; the relative angle between the LED2 and the picture is the second smallest, a median bit is allocated for the LED2, and the weight is N2, namely, the median N2 bit in the whole binary bit data stream is allocated for the LED 2; the relative angle between the LED3 and the picture is the largest, the LED3 is allocated with the low order, and the weight is N3, namely the LED3 is allocated with the low order N3 in the whole binary bit data stream.
In the above embodiment, the relative positional relationship of the LEDs 1,2, 3 and the reference object is pre-stored in the information distribution module of the information transmitting apparatus and the decoding module of the information receiving apparatus. Of course, the number of the LED lamps can be 2, 4, 5, etc., and the number of the LED lamps can be set according to the data quantity required to be transmitted or the requirement of the display room for light.
In the above embodiment, for a more general case, such as N lamps in a room, the total amount of information to be transmitted is I based on the position coding method, namely:
I＝w 1 ×i 1 +w 2 ×i 2 +…+w N ×i N
in the above formula, w n For the weight corresponding to the nth lamp, i n Information amount allocated to the nth lamp, where n=1, 2, …, N.
After the light receiving module of the information receiving device receives the light signals sent by the N light sources, the information conversion module converts the light signals into N data packets, the decoding module decodes the N data packets according to preset decoding to obtain data information and weight information in each data packet, and the N data information is recombined according to the weight information to obtain complete data information.
In order to improve the adaptivity of the data transmission, steps 901 to 903 are further included before the above step 201.
In step 901, a light source is caused to emit a light signal containing an identification of an illuminated object.
In step 902, the optical signal reflected by the irradiated object is received, the identifier is obtained from the optical signal, and the identifier is sent to a remote server.
In step 903, the remote server is caused to transmit data information corresponding to the illuminated object based on the identification.
Where the mark for irradiating an object refers to the position of the irradiated object, for example, as shown in fig. 1, the irradiated object is a picture, and the mark of the picture is the position of the picture. The positions of the drawings and the data information corresponding to the drawings are configured in pairs in a remote server.
In the implementation, one LED lamp is selected as a lamp for emitting the light signal containing the identifier of the irradiated object in the booth, and the LED lamp may be one of the LEDs 1,2 and 3 which need to emit the light signal containing the data information of the irradiated object, or another LED lamp may be provided and is specially used for emitting the light signal containing the identifier of the irradiated object. The latter example is described as an example. As shown in fig. 10, a lamp LED4 is added to the wall of the booth on the basis of fig. 1.
In the implementation, as shown in fig. 11, the information sending device further includes an identification driving module and an LED4 driven by the identification driving module. The above step 901 is performed by the sign driving module, i.e. the sign driving module causes the LED4 to emit a light signal containing a sign of the illuminated object, i.e. a picture on a wall, where the sign may represent the position of the illuminated object.
Specifically, as shown in fig. 12, the information receiving apparatus further includes an identification transmitting module. The step 902 is implemented by an information receiving device, that is, the light receiving module receives the light signal containing the identifier of the irradiated object after being reflected by the irradiated object, and transmits the light signal to the information converting module; the information conversion module acquires the identification of the irradiated object from the optical signal and sends the identification to the identification sending module; the identification transmitting module transmits the acquired identification of the irradiated object to the remote server, so that the remote server can transmit data information corresponding to the irradiated object according to the identification of the irradiated object. The identification (position information) and the corresponding data information of each collection in the museum are stored in a remote server in a matched mode, and the remote server can find the corresponding data information according to the identification. Therefore, after receiving the identifier sent by the identifier sending module in the mobile phone held by the tourist, the remote server searches the storage module for the data information matched with the identifier, and then sends the data information to the information sending device.
Specifically, in the booth, the LED4 can emit an optical signal containing the logo (positional information) of the drawing in fig. 1 under the drive of the logo driving module. The light signal is reflected by the picture after being irradiated on the picture; when a tourist shoots the picture by using the handheld terminal, the light receiving module can receive the light signal which contains the mark of the irradiated object and is reflected by the irradiated object. The information conversion module of the handheld terminal can acquire the identification of the irradiated object from the optical signal and send the identification to the identification sending module. The identification transmitting module receives the identification from the identification transmitting module and transmits the identification to the remote server. After receiving the identification, the remote server searches the storage module for the data information matched with the identification, and then sends the data information to the information sending device.
