The embodiment of the invention provides a fixed position distribution method based on Bluetooth, as shown in figure 2, comprising the following steps:
s101, the mobile terminal sends a queuing request to a background server.
And the background server is used for adding the mobile terminal into a queue after receiving the queuing request.
Specifically, the designated area may be a preset indoor or outdoor area, such as a public dining area of a dining hall, a seat area of a food square, a seat area of a library, and the like. Often such designated areas have well-defined boundaries, such as the walls of the lobby in an indoor area, and many fixed points are provided, such as each table in a public dining area as a fixed point. The positioning base station is installed in a designated area, for example, can be installed in a corner of the designated area.
S102, the mobile terminal receives the position information of the fixed point in the idle state sent by the background server, and after entering a designated area, the mobile terminal communicates with at least 2 positioning base stations in the designated area.
Wherein, each positioning base station is provided with at least one Bluetooth module. Each positioning base station is provided with at least one Bluetooth module. Specifically, in the positioning base station in this embodiment, the bluetooth signal is transmitted by using a transmitting antenna array. The positioning base station switches different transmitting antennas according to a preset sequence to transmit a CTE signal (Constant Tone Extension). The mobile terminal extracts IQ (In-phase and quadrature) samples from the CTE signal sent by the positioning base station, and acquires the direction of the CTE signal according to the obtained IQ samples.
For example: as shown in fig. 3, the positioning base stations are arranged at a plurality of points in a designated range, such as a public dining area of a restaurant, the positioning App can be integrated with a customer ordering App, and the positioning processing background is in the cloud. The positioning App and the positioning base station in this embodiment are based on the AoD technology of bluetooth 5.1, and a mobile phone (i.e., a user terminal) equipped with the positioning App is required to support the AoD technology of bluetooth 5.1. The principle of AoD implementation broadly includes: the transmitter adopts an antenna array, the receiver is a Bluetooth remote controller or a mobile phone App, and the receiver only has one antenna. When the transmitter switches different transmitting antennas in a certain order to transmit a fixed frequency Extension signal (CTE), the receiver extracts IQ samples, and calculates the direction of the signal according to the different IQ samples. The real-time position display software can be operated on the user terminal and/or the service terminal and is used for displaying the current position of the user equipment on the operated terminal equipment.

And S104, displaying the position of the mobile terminal on the electronic map of the designated area, displaying a navigation path from the current position of the mobile terminal to the fixed point on the mobile terminal, and judging that the mobile terminal is occupied after moving to the fixed point.
Specifically, still include: when a release event triggered by the mobile terminal is detected, releasing a fixed point occupied by the mobile terminal; and transmitting the position information of the released fixed point to the service terminal. So as to inform the attendant holding the service terminal of the cleaning in the future.
In some possible implementations, the release event includes:
the position of the mobile terminal deviates from the fixed point by more than a maximum value; or, the mobile terminal sends an end message to the background server. So that after the previous customer finishes dining and checks out, the seat of the previous customer is released in the restaurant processing background and the next customer is informed to have a meal in combination with the queuing system.
Further, the method also comprises the following steps:
the background server receives the ordering information sent by the mobile terminal after receiving the queuing request sent by the mobile terminal; and adding the mobile terminal into a queue after confirming that the mobile terminal completes payment according to the ordering information. In order to guide the customer to the assigned seat (i.e., the fixed point in the idle state assigned to the user terminal) after the customer successfully takes a meal from the store or window while waiting by using the restaurant App.
In practical applications, taking a scene that a customer arrives at a restaurant for dining as an example, a specific implementation flow may include:
1. after the customer arrives at the restaurant, opening the restaurant App to make a meal order;
2. the queuing and calling process is processed in a restaurant processing background;
3. in the waiting process, a customer can use the restaurant App to order in advance;
4. after the previous customer finishes dining and settles accounts, the seat of the previous customer is released in the restaurant processing background, and the next customer is informed to have a meal by combining with the queuing system;
5. after the restaurant App of the waiting customer reminds to call the number, the mobile phone App of the customer can communicate with a navigation base station in the restaurant in real time, calculate the current position of the customer and then display a navigation path of the current position reaching the table in real time;
6. and the customer walks to the table for dining according to the navigation path.

and the mobile terminal selects the nearest 2 positioning base stations in the specified area according to the result of RSSI (Received Signal Strength Indication) estimation.
For example, as shown in fig. 6, when a customer opens a positioning App on a user terminal to enter a restaurant, the App communicates with two base stations in the restaurant in real time, and the two base stations are selected by estimating and selecting the nearest two base stations based on RSSI generally, the App can calculate the current included angles α and β with the base stations through AoD technology, each of the restaurant is provided with one positioning base station which is composed of a bluetooth module based on bluetooth AoD technology and a related power supply, if the restaurant has a large internal space, the number of deployment points is increased, when the customer opens a specific positioning App to enter the restaurant, the App communicates with the two base stations in real time, the two base stations are selected by estimating and selecting the nearest two base stations based on RSSI, the App can calculate the current included angles α and β with the base stations through AoD technology, the distance L between the base stations A, B is a fixed value, T is a target position, T is known as an included angle between a and T2, and T2 is determined, and the initial position information can be calculated by a coordinate axis (38764) of the coordinate axis of the typical positioning point:
further, in order to further increase the positioning accuracy, the App selects other two base stations to calculate the azimuth for cross-validation, and the more the number of points of the positioning base station is, the more the accuracy is. Therefore, the embodiment may further include in practical application:
and after the included angles between the 2 positioning base stations closest to the designated area are obtained and the initial position information is determined, selecting the 2 positioning base stations from the designated area again.
Wherein the 2 reselected positioning base stations are not identical to the nearest 2 positioning base stations.
Specifically, the second location information may be obtained by reselecting 2 positioning base stations. And then verifying the initial position information by using the second position information.
Further, in this embodiment, the method further includes:
and displaying the position of the mobile terminal on the electronic map, and displaying the position to the mobile terminal.
And receiving transposition information sent by the mobile terminal. And updating the target position on an electronic map displayed to the service terminal.
Wherein the transposition information points to a target position in the designated area. The target position is different from the position displayed by the mobile terminal on the electronic map. For example: the background server forwards the positioning information of the user to real-time position display software of the restaurant, such as a personal computer of a reception class, a smart phone of a waiter and the like. The restaurant waiter can quickly find the customer according to the graphical customer real-time position. Specific examples thereof include: after the customer enters the restaurant, the restaurant waiter locates the customer's location as follows: in a restaurant range, a customer opens a user terminal and operates a positioning App therein, the user terminal interacts with a positioning base station in real time, and the App acquires positioning information; the user terminal transmits the positioning information to a positioning processing background; the positioning processing background forwards the positioning information of the user to real-time position display software of the restaurant; the restaurant waiter can quickly find the customer according to the graphical customer real-time position.

Or when the position deviation of the mobile terminal is detected to exceed a threshold value, generating the transposition information according to the current position of the mobile terminal. For example: the user does not click on the user terminal, but directly moves to a new fixed point (such as a dining table) so as to generate deviation from the original position, and if the deviation is greater than a threshold value (such as the threshold value is half of the distance between two fixed points), the transposition information is generated according to the current position of the mobile terminal.
In the existing scheme at present, the positioning is mainly performed through wireless hot spot positioning or a signal intensity positioning mode is adopted, the positioning accuracy is low, and the accurate positioning of a seat (below meter) cannot be realized. Or the customer brushes the two-dimensional code on the table to occupy the space, but the user cannot know whether the seat is occupied before scanning, and the space occupation conflict with other customers can be caused once the customer leaves the seat. This embodiment adopts the wireless location technique based on the bluetooth, and is simple at dining room internally mounted, and the customer also only need operate the cell-phone, has broken away from the meal tablet, has really realized the noninductive location, has solved simultaneously that wiring, later maintenance are complicated and problem with high costs earlier.
