Bluetooth-based fixed position positioning method and system

Abstract

The embodiment of the invention discloses a Bluetooth-based fixed position positioning method and system, relates to the technical field of Bluetooth in a wireless communication technology, and aims to reduce the use cost, improve the dining efficiency of customers and reduce the operation complexity of the customers. The method comprises the steps of after entering a designated area, communicating with at least two positioning base stations in the designated area by the mobile terminal, wherein at least one Bluetooth module is installed in each positioning base station; obtaining initial position information of the mobile terminal in the designated area, and transmitting the position information to a background server; and displaying the position of the mobile terminal on the electronic map of the designated area, and displaying the position to a service terminal. The method and the system are suitable for restaurant service personnel to quickly search seated customers.

Description

technical field [0001] The invention relates to the technical field of bluetooth in the wireless communication technology, in particular to a bluetooth-based fixed position positioning method and system. Background technique [0002] At present, in the food courts of many business districts, in the canteens of large enterprises and schools, more stores will be opened at the same time, and the seats in the dining area are shared, which involves the problem of seat occupation in practical applications. Scanning the QR code on the desktop and ordering food through the mobile phone solves the problem of seat occupancy, but this method is mainly used in a single restaurant or restaurant, in a multi-store cafeteria or food court, in order to protect yourself For the purpose of turnover, there will be situations where shops compete for seats for diners. Moreover, the customer cannot know whether the seat is already occupied before scanning. If the customer who originally occupied ...

Problems solved by technology

Scanning the QR code on the desktop and ordering food through the mobile phone solves the problem of seat occupancy, but this method is mainly used in a single restaurant or restaurant, in a multi-store cafeteria or food court, in order to protect yourself For the purpose of turnover, there will be situations where shops compete for seats for diners

In addition, customers cannot know whether the seat is occupied before scanning. If the customer who originally occupied the seat leaves temporarily, the problem of repeated seat occupation will occur again.

[0003] In the current restaurant positioning system, the customer needs to go to the service counter to order food first and get the designated menu card. After the customer gets the menu card and sits at the seat, he needs to place the menu card in the designated position. If the customer does not swipe the card as required , inserting the card or not placing it in the designated area, the restaurant will not get the location of the customer, that is, the food cannot be delivered quickly. At the same time, the positioning system is wired on each table according to the needs, and the initial installation, wiring costs and later maintenance costs are high.

Or, use a bell-style menu card, ring the bell after the meal preparation is completed, and let the customer pick up the meal by himself, which will cause the seat to be occupied when the customer picks up the meal, which will easily cause unnecessary conflicts when there are many people dining

[0004] In recent years, some wireless technologies have been developed for restaurant positioning, such as RSSI-based Bluetooth technology, but its accuracy is very low, such as UWB-based positioning technology, which is expensive and cannot be separated from the menu
