Bracelet/vervel worn in corrected people

Abstract

The invention discloses a bracelet / vervel worn in corrected people. The bracelet / vervel comprises a wristband, a light source, a light detection module, a first Fresnel lens, a second Fresnel lens, an optical structural piece at least provided with a first reflective section and a second reflective section, a control module and a power supply, wherein light transmitted by the light source is transmitted to the optical structural piece after being focused by the second Fresnel lens, and is reflected to the second reflective section by virtue of the first reflective section, and then the light is transmitted to the optical detection module by virtue of the first Fresnel lens; two ends of the optical structural piece are fixedly connected to two ends of the wristband so as to form an annular structure; and the light source, the light detection module and the control module are connected to the power supply. The bracelet / vervel disclosed by the invention, by virtue of the Fresnel lenses which are capable of focusing light, is capable of enhancing the intensity of an optical signal, and the bracelet / vervel is capable of improving connecting strength and product stability by virtue of the optical structural piece; and by arranging a circuit inside the wristband, the bracelet / vervel is more comfortable to wear and is better in waterproofing performance.

Description

technical field [0001] The invention relates to the technical field of public security, in particular to a bracelet / foot ring worn by orthodontists. Background technique [0002] In the existing technology, the monitoring bracelets / foot rings for correction personnel mostly use wires as the anti-dismantle technical means, there is a possibility of bypass, easy to false alarm after immersion in water, and the stability is poor, and optical fibers are also used as anti-dismantle protection means However, the optical signal transmitted in the optical fiber is relatively weak, and the connection is not strong enough; on the other hand, the wristbands / footbands worn by current orthodontists are generally bulky and not convenient and comfortable to wear. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a wrist / foot ring for orthopedic personnel with stable and reliable performance, not easy to disa...
