在本实施例中，所述智能硬件通过光信号将需要传递的信息传递出去，根据智能硬件的智能化程度的不同，智能硬件可以自动获取某种信息数据，并将自动获取到的信息数据转换成特定形式的光信号发射出去，也可以通过另一设备将需要传递的待传递信息配置写入所述智能硬件，然后通过智能硬件的发光模块和信息转换装置将所述待传递信息转换成特定形式的光信号发射出去，以单光源为例，开始信息为以20Hz频率闪烁10次，间隔0.5s，40hz频率闪烁10次，周期性重复三次。所述智能硬件可以是只包含将所述待传递信息转换成特定形式的光信号的信息转换装置和发光模块，还可以包括自动获取不同数据信息的信息采集模块，如温度传感器、湿度传感器、血压传感器、加速度传感器、重力传感器等采集用户运动指标、健康指标以及周围环境指标的各种功能性传感器。智能硬件根据尺寸大小及功能强度的不同，可以设计成实现更多功能的智能设备，但每一智能硬件必须包含用于信息传导的最基本的信息转换装置及发光模块，以及连接所述信息转换装置和发光模块的发光电路，在需要传导信息时，由信息转换装置将需要传递的信息以特定算法转换成发光指令发送至发光电路，发光电路驱动光源，也即发光模块，按照所述发光指令以亮、不亮两种状态来表达信息，光源在一段时间内的明暗变化构成信息本体，所述光源模块可以是单色单光源、多色光源或线性排列或以阵列形式排列的多光源，根据光源数量的不同，所传递信息的个性程度也不相同，能够增加信息传导的辨识度和准确性。In this embodiment, the intelligent hardware transmits the information that needs to be transmitted through the optical signal. According to the intelligence degree of the intelligent hardware, the intelligent hardware can automatically acquire certain information data, and convert the automatically acquired information data. The specific form of the optical signal is transmitted, and the information to be transmitted that needs to be transmitted is configured to be written into the intelligent hardware by another device, and then the information to be transmitted is converted into a specific by the lighting module and the information conversion device of the intelligent hardware. The form of the optical signal is emitted. Taking a single light source as an example, the start information is flashed 10 times at a frequency of 20 Hz, with an interval of 0.5 s, and the frequency is flashed 10 times at a frequency of 40 hz, and is repeated three times periodically.

Depending on the number of light sources, the degree of personality of the transmitted information is also different, which can increase the identification and accuracy of information transmission.
进一步地，所述当所述闪光信息满足第一预设条件时，开始对所述光信号进行存储的步骤包括：Further, when the flash information meets the first preset condition, the step of starting to store the optical signal includes:
预设一段闪光信息作为开始信息；Preset a piece of flash information as a start message;

If yes, the information content after the field header is valid information, and the information content is started to be stored.
在本实施例中，为了便于App终端更快速、高效地从智能硬件发射的光信号中获取相应的待传递信息，也为了进一步减少App终端的运算量，提高App终端的运算处理速度，减少垃圾信息占App终端的内存，在App终端对智能硬件发射的光信号进行采集存储时，预设一段闪光信息作为开始信息，当App终端的图像采集模块检测到有近似特征的光源时，将具有近似特征光源的光信号转换为光电变换数据的闪光信息与预设的开始信息进行对比判断，也即判断所述闪光信息中的字段头与开始信息的重合率是否达到预设阈值，当所述字段头与开始信息达到预设重合率时，判定所述闪光信息中字段头之后的信息内容为有效信息，以单光源为例，开始信息为以20Hz频率闪烁10次，间隔0.5s，40hz频率闪烁10次，周期性重复三次，当图像采集模块11检测到上述20Hz或40Hz光源时，即开始进行信息采集及比对，若采集到两个完整的周期，则视为信息有效，开始对所述信息内容进行存储；如果所述字段头与开始信息的重合率未达到预设阈值，则判定该闪光信息中的字段头之后的信息内容为无效信息，此时智能硬件发射的光信号为非关联信号，与进行信息传导的光信号不匹配，也就没必要再对该光信号进行处理了，减少了App终端的运算量，提高App终端的运算处理速度。In this embodiment, in order to facilitate the App terminal to obtain the corresponding information to be transmitted from the optical signal transmitted by the intelligent hardware more quickly and efficiently, and to further reduce the calculation amount of the App terminal, the processing speed of the App terminal is improved, and the garbage is reduced. The information occupies the memory of the App terminal. When the App terminal collects and stores the optical signal transmitted by the intelligent hardware, a flash information is preset as the start information. When the image acquisition module of the App terminal detects the light source with the approximate feature, it will have an approximation. The flash signal of the characteristic light source is converted into the flash information of the photoelectric conversion data and compared with the preset start information, that is, whether the coincidence rate of the field header and the start information in the flash information reaches a preset threshold, when the field is When the head and the start information reach the preset coincidence rate, it is determined that the information content after the field header in the flash information is valid information, taking a single light source as an example, the start information is blinking 10 times at a frequency of 20 Hz, the interval is 0.5 s, and the frequency is blinked at 40 hz. 10 times, repeated three times periodically, when the image acquisition module 11 detects the above 20 Hz or 40 Hz light source, it is on Performing information collection and comparison.

同理，为了便于App终端更快速、高效地从智能硬件发射的光信号中获取相应的待传递信息，也为了进一步减少App终端的运算量，提高App终端的运算处理速度，减少垃圾信息占App终端的内存，在App终端对智能硬件发射的光信号进行采集存储时，预设另一段闪光信息作为停止信息，当App终端的图像采集模块对匹配的光信号进行采集时，所述字段尾与停止信息达到预设重合率时，判定所述闪光信息中的信息内容为完整的待传递信息，如持续1s不发光，持续60Hz同样频率闪烁1s以上时，停止对所述信息内容进行存储，停止对所述信息内容进行存储；如果所述字段头与开始信息的重合率未达到预设阈值，则判定该闪光信息中的字段尾之后的信息是否为无效信息，若是，则此时智能硬件发射的光信号为非关联信号，与进行信息传导的光信号不匹配，也就没必要再对该光信号转换后的闪光信息进行存储，若判定所述字段尾之后的信息为有效信息则继续对所述有效信息进行存储，减少了App终端的运算量，提高App终端的运算处理速度。In the same way, in order to facilitate the App terminal to obtain corresponding information to be transmitted from the optical signal transmitted by the intelligent hardware more quickly and efficiently, and to further reduce the calculation amount of the App terminal, the processing speed of the App terminal is improved, and the garbage information is reduced. The memory of the terminal, when the App terminal collects and stores the optical signal transmitted by the intelligent hardware, preset another piece of flash information as the stop information. When the image acquisition module of the App terminal collects the matched optical signal, the field end is When the stop information reaches the preset coincidence rate, it is determined that the information content in the flash information is complete information to be transmitted, and if the information is not illuminated for 1 s, and the same frequency is blinked for more than 1 s for 60 Hz, the storage of the information content is stopped, and the stop is stopped. And storing the information content; if the coincidence rate of the field header and the start information does not reach a preset threshold, determining whether the information after the field tail in the flash information is invalid information, and if yes, then the smart hardware transmits The optical signal is a non-correlated signal, which does not match the optical signal for information transmission, so there is no need to Flash information after converting the optical signal is stored, if the information after the information is determined to be valid tail field continues to store the information efficiently, reducing the amount of computation App terminal, to improve the processing speed of the terminal App.
