Problems solved by technology

[0003] It can be seen that the existing ordering device not only cannot locate the customer in real time, but also requires the customer to manually participate in sending a call request before the server can obtain the customer's location. This solution increases the customer's operation steps, which in turn affects the user's dining experience and reduces service efficiency

Embodiment 1

[0044] see figure 1 , this embodiment provides an indoor positioning method, including:

[0045] receiving the sensing signal sent and received by the positioning unit; calculating the distance between the positioning unit and each distributed base station respectively according to the sending and receiving time of the sensing signal; based on the distance between the positioning unit and each distributed base station, obtaining the indoor position of the positioning unit location.

[0046] In order to facilitate understanding, this embodiment takes a restaurant application scenario as an example. When a customer orders a meal at the bar, the waiter will distribute a call plate to the customer. You can carry the number plate with you to sit at any table by yourself. The server calculates the distance between the positioning unit and each distributed base station, and then accurately locates the position of the customer. In addition, there is a call button on the number plate....

Embodiment 2

[0077] This embodiment provides an indoor positioning device, including a sequentially connected server, a positioning unit, and distributed indoor base station units;

[0078] The positioning unit is used to send and receive sensing signals;

[0079] The distributed base station unit is used to calculate the distance between the positioning unit and each distributed base station respectively according to the sending and receiving time of the sensing signal;

[0080] The server is used for locating the indoor position of the positioning unit based on the distance between the positioning unit and each distributed base station.

[0081] Preferably, the positioning unit includes a positioning chip, a microprocessor and an FPC antenna, one end of the FPC antenna is respectively connected to the positioning chip and the microprocessor, and the other end of the FPC antenna is respectively connected to the distributed base station for communication.

[0082] Preferably, the position...

Embodiment 3

[0089] This embodiment provides a computer-readable storage medium. A computer program is stored on the computer-readable storage medium. When the computer program is run by a processor, the steps of the above-mentioned indoor positioning method are executed.

[0090] Compared with the prior art, the beneficial effect of the computer-readable storage medium provided by this embodiment is the same as the beneficial effect of the indoor positioning method provided by the above technical solution, which will not be repeated here.

[0091] Those of ordinary skill in the art can understand that all or part of the steps in the above-mentioned inventive method can be completed by instructing related hardware through a program. The above-mentioned program can be stored in a computer-readable storage medium. When the program is executed, it includes: For each step of the method in the above embodiments, the storage medium may be: ROM / RAM, magnetic disk, optical disk, memory card, and th...

Abstract

The invention discloses an indoor positioning method and device and relates to the field of positioning technologies. Through the indoor positioning method and device, the position of a customer can be acquired accurately in real time without the need for participation of the customer, and the service efficiency of a merchant is improved while customer experience is guaranteed. The method comprises the steps that a sensing signal received and transmitted by a positioning unit is received; according to the receiving and transmitting time of the sensing signal, the distance between the positioning unit and each distributed base station is calculated; and based on the distance between the positioning unit and each distributed base station, the indoor location of the positioning unit is acquired. The method in the scheme is applied to the device.

Description

technical field [0001] The present invention relates to the technical field of positioning, in particular to an indoor positioning method and device. Background technique [0002] With the development of the Internet of Things, the application of indoor positioning technology is becoming more and more extensive. For example, the ordering device used in restaurants, by setting up the ordering device on multiple dining tables one by one, when customers are seated, they need to use the ordering device A call request is sent, and the server locates the table position where the customer is seated based on the call request, and then assigns a waiter to serve the customer. [0003] It can be seen that the existing ordering device not only cannot locate the customer in real time, but also requires the customer to manually participate in sending a call request before the server can obtain the customer's location. This solution increases the customer's operation steps, which in turn a...
