Problems solved by technology

[0003] In the prior art, AOA Bluetooth positioning technology can be used to locate workers in harsh working environments, so as to ensure the position of workers, thereby ensuring the safety of workers; In a harsh working environment, the Bluetooth wristband worn on the wrist will inevitably collide with hard objects during work, thereby causing damage to the Bluetooth wristband, and then losing the positioning effect, which is likely to cause adverse consequences; and the Bluetooth wristband has It has a certain waterproof effect, but if it is in contact with flowing water for a long time, it may cause internal water ingress and affect the normal use of the Bluetooth wristband

specific Embodiment approach

[0032] As a specific embodiment of the present invention, the part of the lower left end of the main body 2 close to the No. 1 slot 13 and the part of the upper right end of the main body 2 close to the No. 2 slot 15 are provided with inclined surfaces.

[0033] During work, the position of the lower left end of the main body 2 close to the No. 1 slot 13 and the position of the upper right end of the main body 2 close to the No. 2 slot 15 are all provided with slopes, and the set slopes generate vacant parts. 13 and the top of the main body 2 will not be blocked when the main body 2 is turned over when it is stuck in the No. Groove 13 and No. 2 groove 15 become easier.

[0034] As a specific embodiment of the present invention, the side wall of the main body 2 is fixedly provided with a No. 1 bump 21 and a No. 2 bump 22 .

[0035] During operation, the side wall of the main body 2 is fixedly provided with the No. 1 bump 21 and the No. 2 bump 22, and the No. 1 bump 21 and the ...

Embodiment approach

[0036] As a specific embodiment of the present invention, the No. 1 protrusion 21 is bent downward, and the No. 2 protrusion 22 is bent upward.

[0037] During operation, the No. 1 bump 21 bends downward, and the No. 2 bump 22 bends upward. This setting generates an inclined surface inclined to the ports of the No. 1 slot 13 and the No. 2 slot 15 relative to the No. 1 slot 13 and the No. 2 slot 15 , so that when the No. 2 bump 22 snaps into the No. 1 slot 13, and when the No. 1 bump 21 snaps into the No. 2 slot 15, it can be snapped in more easily; and when the main body 2 is to be pulled out of the No. 1 slot 13 When with the No. 2 groove 15, the No. 1 bump 21 pushes the No. 2 groove 15, and the No. 2 bump 22 pushes the No. 1 groove 13; the wristband 1 is increased to the No. 1 bump 21 and the No. 2 bump 22. force, so that the main body 2 will not be easily pulled out, avoiding the accidental pulling out of the main body 2 in the case of protection, and this setting is not ea...

Abstract

The invention belongs to the technical field of high-precision positioning, and particularly relates to AOA Bluetooth positioning auxiliary equipment. The equipment comprises a wristband and a main body. An AOA Bluetooth positioning device is fixedly mounted in the main body, and a display screen is fixedly mounted at the top of the main body; according to the invention, a first strap and a second strap are pulled out of the wristband, then the main body is turned over, and therefore the main body is clamped into a first groove and a second groove, namely the first groove and the second groove jointly wrap the main body, so that the main body is protected, the outside is prevented from directly colliding with the main body, and parts of the first strap and the second strap are also clamped into the first groove and the second groove; the wrapping degree of the main body is increased, and the clamping degree of the main body is increased.

Description

technical field [0001] The invention belongs to the technical field of high-precision positioning, and specifically relates to an AOA bluetooth positioning auxiliary device. Background technique [0002] As early as the end of the 19th century, the work of radio direction finding has been researched by Heinrich Hertz and other pioneers. The original working principle is to compare the signal strength of antennas in different directions, and the direction with the strongest signal is considered as the origin of the signal; Throughout the 20th century, in the field of radio direction finding, scientific and technological workers have continuously introduced new methods, and direction finding technology has continued to improve, especially after the introduction of methods involving signal phase comparison, radio direction finding has made significant progress. In the Bluetooth core specification V5.1, on the basis of comparing the mature technologies in the field of radio dire...
