Description

A kind of double-frequency electronic label

Technical field

This utility model relates to liquefied gas bottle electronic monitoring field, and especially, this utility model relates to a kind of liquefied gas bottle Double-frequency electronic label.

Background technology

At present, supervision department is increasing to the supervision of special equipment, and utilizes the requirement of the level of informatization also More and more higher.In order to be able to coordinate supervision department effectively to supervise civil liquefied gas bottle, the Chinese government has promoted " million danger The electronic tag mark of danger chemicals gas cylinder " engineering.By electronic tag, to the registration of liquefied gas bottle, check, fill, change Real-time tracking is carried out with scrapping.By liquefied gas bottle buying, fill, transport, sell, user, the whole intermediate links such as return In electronic tag is carried out Card read/write, it is achieved liquefied gas bottle from archive information, fill production, Logistic Scheduling, sales management, join Send management and customer account management and the standardized administration of after-sale service.Cylinder for liquefied gas electronic tag refers to device record on steel cylinder There is the electronic mark board of steel cylinder annual test information.The all files data of every steel cylinder includes that annual test all stores record at RFID electronics On Sign Board, as long as supervisor utilizes special handheld RFID identification terminal, it is aligned with device electronics on steel cylinder Sign Board, just can obtain the information status such as this steel cylinder annual test.

Generally, electronic tag is made up of plastic base and embedded RFID electronic identification chip.Such as, Chinese patent bulletin CN102226911B discloses a kind of liquefied gas bottle electronic label seal, and this electronic label seal can hang on cylinder for liquefied gas, its It is made up of housing, Steel wire rope lock, bottom and electronic label chip four part；There is individual Inner arc housing tip middle position；Steel wire Cord lock is embedded into interior being sealed by bottom of housing and constitutes an entirety, and electronic label chip is enclosed in enclosure interior；Steel wire rope is embedded into In lock body, as the door lock usually used, can be fixed to firmly on object pin.But due to the most several embedded RFID chip, therefore, there is many inferior positions in this electronic tag in performance.In recent years, the application of double-frequency electronic label is from read-write The many aspects such as distance, wake-up mode, power consumption enhance the performance of electronic tag, and double-frequency electronic label is at an electronic tag In, the RFID chip that integrated two operating frequencies are different.But for cylinder for liquefied gas electronic tag, owing to its volume is little, Ensureing that read-write the most simultaneously, it is also contemplated that and is easy to combine with liquefied gas bottle, further need exist for carrying out when RFID is integrated Particular design, it is to avoid interfere between the RFID chip that operating frequency is different.Therefore, need a kind of double-frequency electronic label badly, will The RFID of two kinds of frequencies is integrated in a medium, while being easy to install on equipment and read and write, two kinds RFID days Interfering of line is minimum.

Utility model content

Based on above-mentioned consideration, this utility model provides a kind of double-frequency electronic label, including: dual-frequency label housing, first RFID chip and the second RFID chip, wherein, affiliated dual-frequency label housing includes kerve and cover plate, described kerve and described lid Plate, respectively by plastics integrated injection molding, the inner bottom surface of described kerve has grid, described first RFID chip are fixed on described On cover plate, described second RFID chip is positioned at described kerve and by described grill support.

Preferably, the steel tie head bottom described kerve with two recessed formation of ecto-entad fixes groove, at the described end On two sides of groove, fix groove with described steel tie head and flush place, be respectively provided with a steel band fixing hole.

Preferably, a lateral outer of described kerve has a boss.

Preferably, described first RFID chip is 13.56MHz chip, and described second RFID chip is 915MHz chip.

Use said structure, coordinate steel band, easily described electronic tag can be fixed on liquefied gas bottle On.Time fixing, steel tie head is positioned at described steel tie head and fixes groove, and steel band is worn from a steel band fixing hole from inside to outside Go out, then ecto-entad is through another steel band fixing hole, thus form one for the steel band hanging described electronic tag Ring.When described steel band is long, can be cut off, termination is stayed at described boss, after covering cover plate, can prevent operator Member scratches.

The reading/writing distance of 13.56M chip is relatively near, fixes on the cover board, during operation close to read write line, it is simple to read-write；915M Chip is fixed in the middle part of kerve, the grid of bottom prop up, and a certain distance is arranged at distance bottom, it is to avoid from gas cylinder metal after installation Face is too near, causes read-write sensitivity decrease, and meanwhile, the interference of two chip chambers is also reduced to minimum.
