Abstract

The present application belongs to the technical field of smart appliances, and relates to a control method for equipment, comprising the steps of: acquiring a user instruction and a target position; acquiring the number of connected terminals of each locator beacon, determining target equipment according to the number of connected terminals of the locator beacon, and controlling the target equipment to move to the target position; acquiring position information of the target equipment, and calculating a distance between the target equipment and the target position according to the target position and the position information of the target equipment; and controlling the target equipment to stop moving when the distance between the target equipment and the target position is less than or equal to a set threshold.

First claim

What is claimed is:

1. A control method for equipment, comprising the steps of:
acquiring a user instruction and a target position;
acquiring the number of connected terminals of each locator beacon;
determining target equipment obtaining the number of connected terminals of the locator beacon between each equipment and the target position by calculating

wherein E m is the sum of the number of connected terminals of n locator beacons between mth equipment and the target position; S i is the number of connected terminals of an ith locator beacon between the equipment and the target position; m is an integer greater than 1; and i and n are both non-negative integers, and i≤n;
controlling the target equipment to move to the target position;
acquiring position information of the target equipment, and calculating a distance between the target equipment and the target position according to the target position and the position information of the target equipment; and
controlling the target equipment to stop moving when the distance between the target equipment and the target position is less than or equal to a set threshold.

2. The method according to claim 1 , wherein the step of determining the target equipment according to the number of connected terminals of the locator beacon between each equipment and the target position comprises:
when the values of E m are not all the same, acquiring a minimum value E mmin of E m , and judging whether the number of equipment corresponding to E mmin is greater than 1; when the number of equipment corresponding to E mmin is 1, taking the equipment corresponding to E mmin as the target equipment; when the number of equipment corresponding to E mmin is greater than 1, taking the equipment with the shortest distance from the target position among the equipment corresponding to E mmin as the target equipment; and
when all the values of E m are the same, taking the equipment with the shortest distance from the target position as the target refrigerator.

3. The method according to claim 2 , wherein the locator beacon between each equipment and the target position is determined according to the coordinates and distances of each equipment and the target position.

4. The method according to claim 3 , wherein a line is made according to position coordinates of each equipment and the coordinates of the target position; a circular area is obtained by drawing a circle with a midpoint of the line as a center and a length from the midpoint to the target position as a radius; and then, the locator beacons inside the circular area are locator beacons between each equipment and the target position;
wherein the locator beacons are Bluetooth beacons;
wherein the target position and the position information of the equipment are obtained by calculating a locator beacon address and a received signal strength indication (RSSI) broadcasted by each locator beacon.

5. The method according to claim 1 , wherein the locator beacon between each equipment and the target position is determined according to the coordinates and distances of each equipment and the target position.

6. The method according to claim 5 , wherein a line is made according to position coordinates of each equipment and the coordinates of the target position; a circular area is obtained by drawing a circle with a midpoint of the line as a center and a length from the midpoint to the target position as a radius; and then, the locator beacons inside the circular area are locator beacons between each equipment and the target position.

7. The method according to claim 6 , wherein the locator beacons are Bluetooth beacons.

8. The method according to claim 7 , wherein the target position and the position information of the equipment are obtained by calculating a locator beacon address and a received signal strength indication (RSSI) broadcasted by each locator beacon.

9. A control device for equipment, comprising a memory storing program instructions, and a processor configured to execute the program instructions, wherein upon execution of the program instruction, the processor causes the control device to perform operations including:
acquiring a user instruction and a target position;
acquiring the number of connected terminals of each locator beacon;
determining target equipment by obtaining the number of connected terminals of the locator beacon between each equipment and the target position by calculating
