Volatile identification code, identification system and checking method
Technical Field
The invention relates to the technical field of marking, in particular to a volatile identification code, an identification system and an inspection method.
Background
As is known, linen is easily infected with germs, and a basic item in hotel management is the management of linen, which usually requires changing linen in a guest room every day, at least every guest. However, in reality, especially in hotels with lower grades, it is not difficult to find out that the linen used by the previous guest is not changed and cleaned but is continuously used by the next guest.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a volatile identification code, an identification system and an inspection method.
In order to achieve the above object, the embodiments of the present invention provide the following technical solutions:
a volatile type identification code which is produced from a decomposition type material or a dissolution type material, and disappears when the volatile type identification code is in a decomposition condition of the decomposition type material or a dissolution condition of the dissolution type material.
According to the embodiment of the invention, the decomposition type material is a high-temperature decomposition material, or the dissolution type material is a water-soluble material.
Further, the volatile type identification code carries information of the volatile type identification code.
Further, the information of the volatile type identification code is displayed only when the volatile type identification code is recognized for the first time.
Furthermore, a fixed identification code for representing the identity of the carrier is also arranged on the carrier. The fixed identification code does not disappear after being arranged on the carrier and can always exist along with the carrier. By identifying the fixed identification code, the basic information of the carrier can be obtained, including but not limited to the identity of the carrier, the manufacturer, the production time and the production address of the carrier, and the manufacturing material or the composition of the carrier.
An identification system comprising a volatile identification code of any embodiment of the invention, and a carrier, said volatile identification code being provided to said carrier.
According to an embodiment of the invention, the carrier is linen.
The system also comprises a scanning terminal which is used for identifying the volatile identification code and displaying the information carried by the volatile identification code.
The inspection method implemented based on the identification system in this embodiment includes the following steps:

Description of the main elements
A volatile type identification code 100; 200 parts of linen; the fixed-type identification code 300.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the identification system provided in the present embodiment includes a volatile identification code 100 and a carrier, where the volatile identification code 100 is disposed on the carrier. The volatile identification code 100 may be provided at any position of the carrier. The carrier in this embodiment may be any article or article package, and the embodiment is only exemplified by the linen 200, and the linen 200 may include, but is not limited to, bedding articles such as bedding quilt cover, cotton quilt core, bed sheet, bed cover, pillow cover, fitted cover skirt, bed tail cushion, protective cushion, and towel products such as face towel, square towel, bath towel, ground towel, bath robe, etc., and also includes table cloth, napkin, chair cover, table skirt, bath curtain, etc., and the linen 200 may be a bed sheet as shown in the figure.
In this embodiment, the volatile identification code 100 is made of a decomposition type material or a dissolution type material, and when the volatile identification code 100 is in the decomposition condition of the decomposition type material or the dissolution condition of the dissolution type material, the volatile identification code 100 is decomposed and disappeared, so that the carrier can be reused, the volatile identification code 100 is arranged before the carrier is used, the volatile identification code 100 is removed after the carrier is used, and a new volatile identification code 100 is arranged before the carrier is used next time.
Taking the linen 200 used in the hotel guest room as an example, the linen 200 used by guests needs to be cleaned and/or sterilized, and the sterilization mode can be high-temperature sterilization, so the material for manufacturing the volatile identification code 100 can be water-soluble material or high-temperature decomposition material, if the volatile identification code 100 is made of water-soluble material, the volatile identification code 100 on the linen 200 disappears after the linen 200 is cleaned by water; if the volatile identification code 100 is made of a high-temperature decomposition material, the volatile identification code 100 on the linen 200 can be removed through high temperature in the disinfection or cleaning process.
It should be noted that, for linen, the volatile identification code 100 may be made of a water-soluble material or a pyrolysis material, and for other carriers, the volatile identification code 100 may be made of other pyrolysis materials or dissolution materials, and is not limited to the pyrolysis material or the water-soluble material.
The linen 200 in the hotel is cleaned and disinfected through the water washing center, and then the cleaned and disinfected linen 200 is returned to the hotel. In order to ensure the fairness and the reliable implementation of the checking effect, the volatile identification code 100 is preferably set by a third-party supervision platform, namely, the volatile identification code 100 is issued by the third-party supervision platform, and the hotel and the washing center only serve as users. The hotel will make used linen 200 send to the washing center, the washing center dries or dries after cleaning and disinfecting linen 200, after linen 200 was dried by cleaning and disinfecting, send to third party supervision platform by the washing center, third party supervision platform sprays volatile type identification code 100 on linen 200 through spouting yard equipment, perhaps use the sign indicating number equipment of third party supervision platform mandate to spray volatile type identification code 100 on linen 200, then send the linen 200 that is provided with volatile type identification code 100 back to the hotel by third party supervision platform. Therefore, by using the identification system described in this embodiment or by arranging the volatile identification code 100 described in this embodiment on the linen 200, the situation that the washing center sends the linen 200 sent by the hotel back to the hotel without cleaning can be avoided. Before the guest live in, whether the guest room linen 200 is replaced or not can be checked by checking the volatile identification code 100, so that the situation that the restaurant does not send the linen 200 used by the guest to a washing center for cleaning is avoided.
The volatile identification code 100 may carry information, which may be information of the volatile identification code 100 and/or information of the carrier. The manner of carrying the information may also vary depending on the form of representation of the volatile identification code 100. For example, when the volatile type identification code 100 is expressed in a form of a character string, after the volatile type identification code 100 is sprayed on the linen 200, the third party supervision platform writes related information of the volatile type identification code 100 and/or the linen 200 in the query database, such as the cleaning time of the linen 200, the code spraying time of the volatile type identification code 100, the cleaning grade of the linen 200, the identification (such as a serial number) of the linen 200, the identification of the volatile type identification code 100, and the like, and during the examination, the third party supervision platform can log in a query website to input the character string, so that the related information of the linen 200 can be consulted, and whether the linen 200 is cleaned and replaced or not can be judged. The character string may be an english alphabet, and/or an arabic numeral. For another example, when the expression form of the volatile identification code 100 is a two-dimensional code, the two-dimensional code may be scanned by a scanning terminal such as a mobile phone, and the information related to the linen 200 may be directly displayed on the mobile phone after scanning. By checking the information of the volatile identification code 100 and/or the information of the carrier, whether the linen 200 is the changed linen 200 can be further more accurately judged.
In the present embodiment, the expression form of the volatile identification code 100 is most preferably a two-dimensional code, based on the maturity of the two-dimensional code technology and the convenience of use. It will be readily appreciated that the volatile identification code 100 may also be in other forms of presentation, such as a bar code, three-dimensional code, etc.
To further improve the accuracy of the result of the verification, the information carried in the volatile identification code 100 can be viewed only once, i.e., the information carried in the volatile identification code 100 can be displayed only when the volatile identification code 100 is recognized for the first time. For example, the relevant information may be displayed when a string is first entered, while the third party supervision platform marks the string as recognized, does not display any information when the string is again entered, or prompts that the string is recognized or verified. For another example, when the two-dimensional code is scanned for the first time, the related information may be displayed, and at the same time, the third party supervision platform marks the two-dimensional code as recognized, and when the two-dimensional code is scanned again, no information is displayed, or the two-dimensional code is prompted to be scanned or checked. In this way, the situation that the used linen 200 is not cleaned and disinfected by a restaurant or a washing center and then is used by the next guest can be further avoided.
As a further preferred embodiment, as shown in fig. 1, the carrier may further be provided with a fixed identification code 300 for characterizing the identity of the carrier. The fixed type identification code 300 does not disappear after being disposed on the carrier, and exists all the time along with the carrier. Through recognizing the fixed identification code, the basic information of the carrier can be acquired, including but not limited to the identity of the carrier, the manufacturer of the carrier, the production time, the production address, the third party supervision authentication identification of the volatile identification code, and the manufacturing material or the composition of the carrier. By reading the basic information of the carrier, whether the carrier belongs to the third party supervision authentication or not can be determined (if the basic information of the carrier contains the third party supervision authentication identification of the volatile identification code, the carrier belongs to the third party supervision authentication, and if the basic information of the carrier does not contain the third party supervision authentication, the carrier can be identified, and the authenticity and quality condition of the carrier can be further identified, so that the phenomena of being good at one time and being fake at one time can be avoided.
The fixed identification code may be expressed in the form of a two-dimensional code, a one-dimensional code, a character string, or the like, and is preferably a two-dimensional code based on the convenience of recognition. In order to facilitate distinguishing and identifying, the character strings of the fixed type identification code and the volatile type identification code are generated to be different character strings. The fixed identification code and the volatile identification code can be arranged at different positions of the carrier, and also can be respectively marked beside the fixed identification code and the volatile identification code by using character patterns or information such as the fixed identification code, the volatile identification code and the like so as to be convenient for distinguishing and positioning during code spraying.
Based on the implementation of the volatile identification code 100 and the identification system, the embodiment further provides a method for checking the guest room linen 200, which comprises the following steps:
step 1: the volatile identification code 100 is identified and an information query request is sent. In this step, the volatile identification code 100 is recognized in different ways according to the expression form of the volatile identification code 100, for example, when the volatile identification code 100 is a two-dimensional code, the two-dimensional code is scanned for recognition, and when the volatile identification code 100 is a character string, the volatile identification code 100 is input to a query website for recognition.
And step 3: in response to the information query request, the information carried by the volatile identification code 100 is displayed.
In order to further enhance the accuracy of the inspection result, the method further includes, before step 3, step 2: and judging whether the information inquiry request is sent for the first time, if so, responding to the information inquiry request, and if not, not responding to the information inquiry request, namely, not displaying any information or displaying prompt information that the volatile identification code 100 is inspected.
It should be noted that, in this embodiment, only the hotel linen 200 is taken as an example for description, and actually, the volatile identification code 100, the identification system and the checking method provided in this embodiment may be applicable to other carriers or scenes, such as disposable medical products, disposable tableware, and the like.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
