Problems solved by technology
[0002] At present, positioning technologies based on radio frequency identification, such as Wi-Fi, Bluetooth, etc., are widely used in positioning indoors and similar environments. This positioning technology has certain requirements for the environment in which radio frequency signals are transmitted. In environments where transmission is more sensitive, such as mines, hospitals, etc., the transmission of radio frequency signals may interfere with the normal operation of some electronic devices (such as cardiac pacemakers, etc.) in these environments, and there are certain potential safety hazards; equipment to ensure ideal positioning stability based on radio frequency signals

Embodiment Construction
[0055] Exemplary embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.
[0056] Here, it should also be noted that, in order to avoid obscuring the application due to unnecessary details, only the device structure and / or processing steps closely related t...

The invention discloses a position information sending method, a position information sending device, a positioning method, a positioning device and a positioning system. The position information sending method comprises the following steps of acquiring first coverage position information of a first luminescent source; modulating the first coverage position information in first light rays emitted by the first luminescent source. The positioning method comprises the following steps of receiving the first light rays emitted by the first luminescent source; demodulating the first light rays to acquire the modulated first coverage position information of the first luminescent source in the first light rays; positioning at least according to the first coverage position information. The influence of positioning on the privacy of a receiving end is avoided, and the diversified actual application requirements of a user are met.
Description
technical field [0001] The present application relates to the technical field of optical communication, and in particular to a location information sending method and device, a positioning method and device, and a positioning system.
