Collaborative orientation method based on bluetooth equipment and collaborative orientation device based on bluetooth equipment

Abstract

The technical scheme comprises a collaborative orientation method based on bluetooth equipment and a collaborative orientation device based on the bluetooth equipment. The method comprises the steps that the corresponding space coordinates are established for the master bluetooth equipment and multiple sets of slave bluetooth equipment, including determining the center point of multiple sets of slave bluetooth equipment, wherein each bluetooth equipment is corresponding to one node; the corresponding rotatable radio baffle is set for each set of bluetooth equipment and controlled, and communication between the master bluetooth equipment and multiple sets of slave bluetooth equipment is established; and the RSSI values of multiple sets of slave bluetooth equipment in case of communication are acquired, and the direction of the master bluetooth equipment is calculated according to the acquired RSSI values. The beneficial effects of collaborative orientation method based on the bluetoothequipment and the collaborative orientation device based on the bluetooth equipment are that the radio directivity is utilized; different RSSIs are formed through the baffle and the rotation mode; andthe equipment is portable, simple and low in cost without environmental limitation.

Description

technical field [0001] The invention relates to a bluetooth device-based cooperative orientation method and device, belonging to the field of computer communication positioning. Background technique [0002] In the current environment of rapid development of the Internet of Things, it is very important to determine the position and direction of objects. The position and direction of the object can be determined by the delay difference of radio communication and the quality of the signal and other related indicators. The present invention judges the direction through the communication quality state between BLE communication devices. [0003] Currently existing technologies that are relatively similar to the present invention are positioning or orientation through radio waves, such as GPS and multi-node space positioning. [0004] The disadvantages of GPS are: [0005] 1. It can only be positioned on a plane; [0006] 2. The equipment needs to be able to receive satellite ...
