Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The Bluetooth device-based cooperative orientation method and device of the present invention determine the relative directions between different objects.

[0026] figure 1 Shown is an overall flow chart according to an embodiment of the present invention. The method of adding blocking between the radios makes the antenna signal directional, and then judges the relative position of the devices communicating with each other through the communication quality. The signal quality is the best when there is no obstruction between radio signals, and the communication quality will be poor when there is obstruction. Therefore, the relative direction between the devices is calculated according to the signal quality RSSI between the antennas and the obstructi...

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 ...
