Problems solved by technology

[0006] However, since the location of the Wi-Fi wireless router is relatively fixed and the signal transmission distance reaches tens or even hundreds of meters, all mobile smart devices within the coverage of the Wi-Fi signal can only be stored in the Wi-Fi wireless router at one time. The location data of the location server shall prevail, and the error may sometimes reach tens of meters, especially for wireless routers with wide Wi-Fi signal coverage
In addition, this technology is limited by the scope of the service, it cannot provide navigation data such as direction, speed, and cannot be used offline

Embodiment

[0035] Example: figure 1 It is a structural schematic diagram of an LED lighting device with a built-in Wi-Fi module of the present invention, such as figure 1 As shown, the LED lighting device 60 includes a driving power supply 61 , an LED lighting component 62 , a Wi-Fi module 63 and a radio frequency antenna 64 . Wherein said driving power supply 61 is electrically connected with the LED lighting assembly 62 and the Wi-Fi module 63 and provides them with power and related control signals, and is electrically connected and mutually connected between the Wi-Fi module 63 and the radio frequency antenna 64. transmit radio frequency signals.

[0036] The LED lighting device 60 is not limited to figure 1 The shape shown does not specifically refer to a single light source, such as a single light bulb, but it may also include a light fixture equipped with multiple light bulbs. The driving power of these light bulbs can also be connected to the same Wi-Fi module or controller to...

Abstract

The invention discloses an indoor navigation control system and method based on LED lighting devices. A characteristic that the LED lighting devices are widely distributed indoor and relatively fixed is used and a Wi-Fi module is arranged in each LED lighting device. Position information of each LED lighting device is stored in a position server in the name of a unique MAC address of the LED lighting device, that is, an actual geographic position of each LED lighting device is bound with the unique MAC address of the LED lighting device. When a user enters an unfamiliar building, an intelligent terminal is used to communicate with the LED lighting devices and the position server so as to acquire a node planar distribution diagram of room distribution as if a map is generated so that the system is capable of providing Wi-Fi indoor positioning and navigation more accurate than a conventional wireless router. Moreover, if the indoor navigation control system is applied to large-scale places such as supermarkets, exhibition halls and museums and the like, related promotion or tour information and the like can be pushed according to a current position of a user.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to an indoor navigation control system and method based on an LED lighting device. Background technique [0002] Due to many advantages such as energy saving, environmental protection, light control, solidification, and long life, LEDs have been widely used in various lighting fields today when low-carbon life is advocated. [0003] With the progress of human society, people pay more and more attention to the precise positioning of their own location and the navigation of places of interest. Global Positioning System (GPS), cellular base station positioning and Wi-Fi hotspot positioning have become the most commonly used positioning technologies. GPS technology uses the signals emitted by satellite groups evenly distributed around the earth to achieve precise positioning outdoors in an open environment. It has the characteristics of global coverage, 24-hour all-weather work, w...
