Packaging device dynamic locking method

Abstract

The invention provides a packaging device dynamic locking method, and relates to an electronic technology and a communication technology. The method provided by the invention comprises the steps that1) a signal transmission channel is set at the opening of a packaging device, so as to form the corresponding relationship between 'the signal transmission channel remains intact-the packaging deviceis not turned on unauthorizedly' and 'the signal transmission channel is destroyed-the packaging device is turned on unauthorizedly'; 2) a predetermined signal is sent by a signal transmitting deviceand is transmitted to a signal receiving device through the signal transmission channel, and the signal receiving device records the signal information; and 3) the signal information is verified according to a predetermined rule, and whether the packaging device is turned on unauthorizedly is judged. According to the invention, the security of a lock body is ensured by means of dynamic real-time communication verification and recording, which effectively prevents unauthorized illegal unlocking; the method has the advantages of simple structure, high confidentiality, low power consumption, highapplicability, low cost and convenient centralized management and deploying and the like.

Description

technical field [0001] The present invention relates to electronic technology and communication technology. Background technique [0002] With the increasing maturity of the consumer market and the continuous convenience of logistics and transportation, the anti-opening protection and centralized control of items are becoming more and more important. Lock the storage carrier of the article by means of stickers, airtight packaging bags, ropes, hardware locks or intelligent electronic locks, or special safe boxes, so as to ensure that it is not opened by a third party during storage and transportation, which will affect, damage or exchange Items in the box. [0003] There are two application scenarios involved. First, it needs to be strictly prevented from being opened by others during transportation and storage. Second, it is only necessary to verify whether it has been opened by others during transportation and storage. Among them, in Scenario 2, accurate identification ...

AI Technical Summary

Problems solved by technology

Often only a single box is locked and one lock requires one key, and multiple locks require multiple keys. The key and the electronic lock are fixed in advance, which is not suitable for logistics and transportation locks that require frequent and dynamic matching of keys and locks. Case

At the same time, the separate storage of a large number of items cannot be centrally controlled and tracked, and it also has the disadvantages of high cost, large size, and inability to centralize, manage, and query. The applicable scenarios are narrow and cannot meet the growing general logistics needs. Confidentiality requirements during transportation and increasing requirements for separate storage and centralized control of a large number of items

At the same time, the active structure of the locking part of traditional electronic locks is often just a simple controlled end that is opened after receiving a signal. Risk of the control line being influenced, hacked or cut by a third party, thereby rendering the locking function ineffective

At the same time, although individual existing electronic locks can control and manage multiple locks through graphic identification codes, remote controls, input passwords, mobile terminals, etc., without a unique entity key participating in centralized management, they still There are potential safety hazards such as identification communication being intercepted by Zhongtong, passwords being snooped on, and users cannot add or remove the pairing management of keys and locks by themselves.

[0005] As far as scenario 2 is concerned, ordinary one-time vulnerable adhesive stickers, sealed packaging bags, one-time sealed ropes, and reliable transport personnel are generally used, which cannot prevent repackaging and individual transport personnel after opening. Lack of professional ethics

At the same time, this inspection will also cause additional material consumption

There are also a small number of electronic locks with a locking active structure driven by electronic equipment for transportation and storage. Due to the need for locking structures and active structures that drive the locking structure, additional production costs for the box will be added to ensure the normal and effective opening of the box. There are problems of large size, high cost, and high power consumption, and often require frequent battery replacement or charging, which is not suitable for the transportation and storage of one-time ordinary packages. A large degree of customization is carried out to meet the size characteristics of different objects, which limits its applicable scenarios to a large extent. It is mainly used for unlocking under encrypted conditions, and it cannot satisfy the general consumer's demand for electronic locks. The need to open verification halfway

At the same time, the existing electronic locks still do not perform dynamic continuous number verification on the closed circuit of the closed surface of the locked carrier, and there is still a risk of being affected by a third party, intruding or cutting off the control line, and thus the verification function will be invalidated.
