Object register system based on mobile phone Bluetooth

Abstract

The invention relates to an object register system based on mobile phone Bluetooth, and belongs to new application of wireless communication technology in the field of object register. The object register system is designed to save the cost of the prior register system, improve code reliability and security, save resources and promote environmental protection. The invention adopts the basic designidea that the Bluetooth wireless technology is used as a code interaction passage of the register system and a user mobile phone end, a user mobile phone is used as a terminal for transceiving codes,an AVR control unit (U1) is a core, and a liquid crystal display module (LCD 1) displays the operation prompt. The system uses an electronic file form as a code carrier to be stored at the user mobile phone end, realizes support for the wider mobile phone end by using OBEX (object exchange protocol) in a Bluetooth protocol stack, has universality, achieves encryption algorithm and stores data byusing hardware, and has high security and stability. The system is popularized and used in a large range to greatly reduce the requirement for printing paper so as to lighten environment pollution generated during papermaking.

Description

technical field [0001] The invention relates to bluetooth communication, and is suitable for public libraries, supermarkets, stations and other places where items need to be automatically stored. Background technique [0002] 1. Search the invention patents of the same technology of the State Intellectual Property Office of the People's Republic of China, and find no patents that achieve the same function as this system. [0003] 2. No similar content was found through the search of literature databases such as VIP. [0004] 3. After searching on the Internet search engine, the common paper-based password storage system is the main one. There are storage systems using IC cards or fingerprints, and the cost is relatively higher than this system. [0005] Traditional item storage systems (such as supermarket bag depositors) almost store passwords through paper media. Doing so can make it easier for users to remember passwords, but it will cause two problems: [0006] 1. Pa...

AI Technical Summary

Problems solved by technology

[0003] 2. No similar content was found through the search of literature databases such as VIP

[0006] 1. Paper passwords are easy to damage, and relatively difficult to save, easy to lose

[0007] 2. There will be a lot of cipher paper scraps around the register, and the used cipher paper will cause environmental pollution to a certain extent

Because the colored writing on thermal paper is unstable and easy to fade, it is easy to make the content difficult to read
