CHARGING PILE

A：(1) Endurance: Capable of lasting over 3 years.

(2) Communication Range: The NB tags utilize China Mobile and China Telecom's NB-IOT networks directly, eliminating the need for additional gateway installations and imposing no communication range limitations; the communication radius between LoRaWAN tags and base stations can extend up to 3KM; BLE tags maintain a stable communication radius exceeding 100M with base stations.

(3) Upload Frequency: Adjustable, with a default upload interval of once every 20 minutes to 4 hours.

A：(1) Battery Life: The positioning collar offers a lifespan of 12-18 months with a replaceable battery, while the BLE collar boasts a battery life of up to 60 months.

(2) Communication Range: The BeiDou MuXun 4G collar utilizes 4G communication technology, allowing for unlimited communication range. The BeiDou MuXun MINI collar employs LoRaWAN technology, achieving a maximum communication distance of up to 5km, with stability maintained above 3km. The BLE collar utilizes BLE technology, ensuring a stable communication radius of over 100m between the collar and the base station.

(3) Upload Frequency: Adjustable, with a default setting of once every 2 hours or 60 minutes.

A：The following factors should be primarily considered:

(1) Cost: Smart ear tags generally have a lower initial purchase cost compared to collars when operating under the same communication mode; however, smart collars can be reused, making them more cost-effective in scenarios that demand long-term usage.

(2) Temperature Measurement: Smart ear tags, worn on the ears of livestock, can accurately capture the temperature in the ear area through a specialized structure. In contrast, since smart collars are positioned on the neck, the animal's skin and fur obstruct effective temperature measurement. Therefore, if temperature monitoring is essential for your livestock, I recommend choosing smart ear tags.

(3) Location Tracking: Due to the high power consumption of GPS/Beidou systems, there is a significant requirement for battery capacity. The tag retention rate cannot meet practical usage needs when ear tags exceed 25 grams in weight. Collars are less sensitive to weight, which means location tracking functionality can only be achieved with smart collars.

(4) Types of Livestock: Some livestock species are unsuitable for wearing ear tags or collars due to their physiological structure. For instance, due to their thick necks, pigs and polled Angus cattle have a high likelihood of collar detachment, making ear tags the only viable option. Additionally, some goats with thinner and more delicate ears also face increased detachment risks with ear tags, hence collars are more appropriate for them.

(5) Farming Scenarios: Beef cattle raised in confinement experience rapid growth, and improperly fitted collars can either fall off if too loose or impede feeding and respiration if too tight, necessitating bi-weekly adjustments that lead to labor inefficiencies and animal stress. In contrast, intelligent ear tags are unaffected by livestock species or growth patterns and do not require adjustments post-application, making them more suitable for confined beef cattle. Conversely, free-range cattle and sheep, which grow at a slower rate, are likely to lose ear tags due to entanglement with fencing and branches; thus, intelligent collars are preferable for them.

(6) Additional Notes: Intelligent ear tags cannot be self-removed or replaced, thereby reducing moral hazard in biological asset supervision. When worn, intelligent collars induce minimal stress in livestock, enhancing animal welfare while also providing more accurate data collection on movement.

A: The combination of tensile strength and material of livestock ear tags is a critical factor influencing the incidence of tag loss. Ear tags with greater tensile strength and enhanced toughness are naturally less prone to detachment. The Zhongnong Zhili intelligent ear tags have undergone extensive tensile testing, utilizing a plastic alloy for the female tag that balances strength and flexibility, capable of withstanding a maximum tensile force (not including TPU male pins) exceeding 700N, significantly surpassing standard ear tags and demonstrating superior strength. The male pins, made from high-quality TPU, achieve a tensile strength of 200N, inducing a recoverable deformation that markedly reduces tag loss due to abrasion and minimizes tearing of the ear.

Additionally, precise positioning during application can further decrease the likelihood of tag loss. When fitting the ear tag, it is essential to install it between the two cartilages of the livestock's ear, approximately one-third of the way toward the base of the ear, while avoiding proximity to blood vessels. Adhering strictly to these positional guidelines is crucial, as improper installation can significantly elevate the risk of tag loss.

A：The smart temperature-measuring ear tag can monitor livestock temperature fluctuations in real time, with the subcutaneous temperature measurement feature achieving an accuracy of 0.1℃ in relation to the actual body temperature of the animals.

A：The positioning method of the smart collar utilizes dual-mode positioning of Beidou/GPS, with an accuracy ranging from 5 to 50 meters, influenced by weather conditions and obstructions.

A:   The smart collar features a specialized structural design that prevents violent disassembly, making it easier to wear with a straightforward clip installation.
