Description

Long distance wireless identification livestock ear tag female buckle structure

The invention relates to a long-distance wireless identification livestock ear tag female buckle structure which can provide long-distance reader, high sensitivity, and low error rate wireless reading and identification benefits under the conditions of miniaturization of livestock ear tags.

According to current standards, in order to regulate the production and operation of animal husbandry, strengthen archives management, establish a traceability system for livestock products, effectively prevent and control major animal diseases, and ensure the quality and safety of livestock products. Animal husbandry laws, animal epidemic prevention laws, and agricultural product quality safety laws in various countries around the world, Develop livestock, poultry, livestock tags, ear tags, electronic tags, foot rings, and other objects that record livestock and poultry information.

For livestock electronic ear tags, such as the new Taiwan patent case No. M394533 "Structure improvement of pig ear tags", a radio frequency (RFID) IC card is provided on the ear tag body (public buckle), or as in M424765 "Ear Tag Structure "Taiwan's new patent case is based on the identification unit (RFID radio frequency identification unit) on the ear tag female fastener; whether it is a radio frequency IC card or a radio frequency RFID identification unit, if high frequency radio frequency (HF RFID) is generally used Technology, tested according to ISO14443 specification. Only one ear tag can be read at a time. The reading distance is short (0 ~ 10cm). The coding is repetitive, which causes many restrictions on management use. Taking ISO15693 as an example, the reading distance is 1 meter. Within, multiple ear tags reading at the same time have the problem of too slow recognition response; if the low frequency radio frequency (LF RFID) technology of the ISO11784 / 11785 standard is used, although the reader's ear tags have a long reading distance (up to 2 Meters), but there are still issues that the reader can only read one ear tag at a time, and one ear tag The reading action takes 1 to 2 seconds to complete, resulting in the lack of inefficient use of this ear tag. UHF RFID technology may improve the above problems. However, UHF radio frequency ( UHF RFID) antennas have been constrained by space on miniaturized ear tags, and have design difficulties. Therefore, the new Taiwan patent case such as M444710 "Ear Tag Structure" is used on a large branded body It is assumed that the radio frequency identification chip (RFID IC) is electrically connected to an antenna capable of sensing electromagnetic signals in the ultra high frequency (UHF) band at a long distance. However, large-scale brand-name electronic ear tags are mounted on the ears of livestock, such as wearing It is carried on pig ears, and its large-scale brand body is vulnerable to being pulled by other pigs. It is very difficult to prevent the antenna from being broken or damaged. Only the traditional miniaturized ear tags are equipped with UHF electronic tags (UHF RFID Tag), and can effectively perform long-distance reading, in order to truly solve the various shortcomings of the conventional livestock electronic ear tags.
