Description

Double-point confirmation intelligent navigation system suitable for complex environment
Technical Field
The invention relates to the technical field of intelligent navigation and positioning, in particular to a double-point confirmation intelligent navigation system suitable for complex environments.
Background
In the field of navigation applications of smart mobile terminals, application schemes have appeared that utilize the bluetooth technology of low power consumption to navigate and realize functions such as commodity propaganda, preferential propaganda, indoor positioning, mapping and the like, such as the iBeacon scheme provided by apple, the iBeacon scheme is equipped with the equipment of Bluetooth Low Energy (BLE) communication function, the BLE technology is used to send own unique ID to the surroundings, and application software receiving the ID can take some actions according to the ID. For example, if the iBeacon communication module is arranged in the shop, an information notification server can be run on the iPhone and the iPad, or a discount coupon and a store-entering point can be sent to the customer by the server. In addition, the iBeacon can be used for sending information to application software when the household appliance fails or stops working. That is, the iBeacon scheme uses a broadcast frame named "Advertising frame" in BLE, where the Advertising frame is a frame that is periodically transmitted and can be received by any device that supports BLE.
The iBeacon technology can also be used for indoor positioning, from the map mapping perspective, iBeacon equipment can send information about the distribution and structure of buildings, the iPhone in the hand of a user can become a map information collector, and the apple company can integrate massive information to obtain indoor map information. In addition, on the premise of providing a rough map, the apple company can also utilize iBeacon to evaluate and verify the accuracy of the map. In the aspect of intelligent home layout, hardware equipment can be integrated with a HomeKit which is an intelligent home technology released by apple Inc., and the HomeKit allows iOS equipment such as iPad, iPhone, iPod touch and the like to be connected to household appliances such as a central air conditioner, a garage door, a door lock and the like; the same core technology of intelligent Internet of things hardware in the Android ecology realizes the interconnection of everything based on the Bluetooth technology.

However, in the current bluetooth-based technical solution, no matter whether the distance is inferred by rssi (received Signal Strength indicator) value or the navigation and positioning are performed by a triangulation method, the change of the position cannot be accurately inferred. The distance of the hardware equipment (similar iBeacon equipment) based on Bluetooth needs to be judged according to the strength of the transmitted signal, and the mode can generate various uncertain results due to uncertain factors such as power stability, battery durability, environmental conditions and the like, so that the effect of accurately navigating in complex environments such as underground parking lots, shopping malls and travel desert routes without network signals with weak signals cannot be achieved.
