As shown in fig. 1, there is a door in the booth, and in this embodiment, the door is used as a reference, and the relative distances between the three LED lamps and the door are used to assign different weights to the lamps (for example, to different positions in the entire binary bit data stream), wherein the LED1 is farthest from the door, the LED1 is assigned high bits, and the weight is N1, that is, the LED1 is assigned high N1 bits in the entire binary bit data stream; the LED2 is second from the door, assigning a median to the LED2 with a weight of N2, i.e., assigning the LED1 the median N2 bits in the entire binary bit data stream; the LED3 is closest to the gate, assigning a low order weight of N3 to the LED3, i.e., assigning the LED3 the low N3 bits of the entire binary bit data stream. Of course, the LED1 may be assigned the low N3 bit, and the LED3 may be assigned the high N1 bit, which is not limited herein.

In the above embodiment, the relative positional relationship between the LED1, the LED2, and the LED3 and the reference object is prestored 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 may be 2, 4, 5, etc., and is set according to the data amount to be transmitted or the requirement of the exhibition room for light.
In the above embodiment, for a more general situation, such as N lamps in a room, the total amount of information to be transmitted is I based on the position coding method, that is:
I＝w1×i1+w2×i2+…+wN×iN

After an optical receiving module of the information receiving device receives optical signals sent by the N light sources, the information conversion module converts the optical 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 recombines the N data information according to the weight information to obtain complete data information.
In order to improve the adaptivity of data transmission, steps 901 to 903 are also included before 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 illuminated 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 according to the identifier.
Wherein the mark for illuminating the object refers to the position of the illuminated object, for example, as shown in fig. 1, the illuminated object is a picture, and the mark of the picture is the position of the picture. The position of the picture and the data information corresponding to the picture are configured in a remote server in pairs.
In an embodiment, an LED lamp is selected in the exhibition room as a lamp for emitting a light signal including the identifier of the illuminated object, the LED lamp may be one of the above-mentioned LED1, LED2, and LED3 that needs to emit a light signal including the data information of the illuminated object, or an LED lamp may be additionally provided, which is specifically used for emitting a light signal including the identifier of the illuminated object. The present embodiment will be described with reference to the latter example. As shown in fig. 10, a light LED4 is added to the wall of the booth, in addition to fig. 1.
In specific 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 identification driving module, i.e. the identification driving module makes the LED4 emit a light signal containing the identification of the illuminated object (i.e. the painting on the wall), where the identification may represent the position of the illuminated object.
Specifically, as shown in fig. 12, the information receiving apparatus further includes an identifier sending module. The step 902 is implemented by the information receiving apparatus, that is, the light receiving module receives the light signal containing the identifier of the illuminated object after being reflected by the illuminated 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 sending module sends the acquired identification of the irradiated object to the remote server so that the remote server can send the data information corresponding to the irradiated object according to the identification of the irradiated object. The identification (position information) of each collection in the museum and the corresponding data information are stored in a remote server in a matching way, 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 visitor, the remote server searches the data information matched with the identifier in the storage module of the remote server, and then sends the data information to the information sending device.
Specifically, in the exhibition room, under the driving of the sign driving module, the LED4 can emit a light signal containing the sign (position information) drawn in fig. 1. The optical signal is reflected by the picture after being irradiated on the picture; when the tourist shoots the picture by using the handheld terminal, the light receiving module can receive the light signal which is reflected by the illuminated object and contains the mark of the illuminated 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. And the identification sending module receives the identification from the identification sending module and then sends 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.
In the above embodiment, the LED4 is used to irradiate the optical signal containing the identification information onto the irradiated object, the irradiated object reflects the optical signal, and the handheld terminal of the guest receives the reflected optical signal containing the identification of the irradiated object, in this transmission mode, the NLos Link (i.e. non-line-of-sight transmission path) is used, and through the non-line-of-sight transmission path, the remote server can transmit the corresponding data information according to the identification information sent by the handheld terminal of the guest after receiving, so that the remote server has adaptivity in data transmission.
