Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0032] A bluetooth device indoor navigation system, reference figure 1 with figure 2 , including: a preset number of Bluetooth devices, the Bluetooth devices are scattered in the target space, and broadcast data packets including the coordinate information of the Bluetooth devices according to the preset frequency; a mobile terminal with Bluetooth, the target space map and the target are preset in the mobile terminal The target position information in the space, the mobile terminal is used to receive multiple data packets at any position in the target space, obtain the coordinate information of the Bluetooth device, calculate the current position information of the mobile terminal and obtain the optimal navigation route.

[0033] Specifically, in this embodiment, the target space is the target parking lot, and the targe...

Abstract

The invention discloses a Bluetooth indoor navigation system, comprising: a preset number of Bluetooth devices which are dispersedly arranged in a target space and broadcast data packets of coordinate information; and a mobile terminal with Bluetooth, wherein the mobile terminal is internally provided with a target space map and target position information, is used for receiving a plurality of data packets at any position in a target space, obtaining coordinate information of the Bluetooth devices, calculating the current position of the mobile terminal and obtaining an optimal navigation route. The target space map and the target position information are preset in the mobile terminal, so that the situation that accurate and effective information cannot be obtained due to weak network signals after a user enters the target space is avoided; the Bluetooth device actively broadcasts the coordinate information and the occupation state information of each parking space, the mobile terminals in the range calculate the navigation route, connection with a server is not needed, and the problems that the underground parking lot is poor in communication quality, network connection is interrupted, navigation information feedback is not timely, and real-time position updating lags behind are solved.

Description

technical field [0001] The invention relates to the technical field of Bluetooth positioning, in particular to an indoor navigation system and a navigation method for a Bluetooth device. Background technique [0002] With the rapid development of the economy and the steady increase in car ownership, there are more and more large parking lots in various cities, especially large underground parking lots in public places such as large commercial buildings, hospitals, and stations. [0003] Due to the tight parking spaces and complex structure of large underground parking lots, difficulty in parking and finding a car has always been two major problems for car owners. By arranging a large number of staff to manually guide vehicles in the parking lot, the problems of parking space allocation and parking space search can be solved. It not only consumes a lot of manpower, increases the operating cost of the parking lot, but also reduces the user experience. Therefore, in the context...
