360 children watch the most users of the attention is the positioning is accurate. Tishen revealed that 360 children's watches are built with five chips and four-reposition technology. The Swiss Ublox GPS chip, auxiliary gravity sensor chip, WiFi chip, Bluetooth chip and GSM chip, and rely on the four-reposition mode to achieve positioning function.

At present, Mercedes-Benz, BMW, Ferrari, Porsche, Audi and other luxury cars are used U-blox products. 360 child guards also achieved accurate satellite positioning by U-blox's GPS chip.

Gravity sensor chip, 360 child defender of the gravity sensor chips from Freescale (36.67, 0.34, 0.94%) company. In 360 child guards, the gravity sensor chip is mainly used for rectifying and calibrating position.

WiFi chips, 360 child defender's WiFi chips and Bluetooth chips are all from Bo Tong (50.49, -0.11, -0.22%), wifi chips are not only used to provide network signals, but also through the WiFi Hotspot location analysis, improve position accuracy.

Bluetooth chip, 360 child defender's Bluetooth chip can guarantee the near-field communication with parents ' mobile phone. In parks, shopping malls and other public places, to open the Bluetooth mode, once the child and parents beyond the safe distance, parents will immediately send alarm alerts to ensure that children in a safe position.

GSM chip, 360 child guardian of the GSM chip from MTK Company, can make 360 children watch anytime, anywhere link mobile network, in the case of poor GPS signals, base station positioning, to protect children's position information at any time access.

For 360 children watch strap material, Tishen revealed that 360 using the United States Dow Corning (17.52, -0.45,-2.50%) company developed food grade silicone rubber,, no use of chemical adhesives in a purely physical way to suppress, does not contain any chemical adhesives, the outer layer of the use of hard glue, the inner use of soft glue, The soft glue interior wraps the antenna.

He pointed to the 360 children's smart watch strap explained that the strap on the back of the bracelet is about 0.38 millimeters, the guide groove and the 9 holes on the strap to form an air corridor to ensure air flow, so that the wrist keep dry.

On the battery side, Tishen said, 360 children's watches using gel polymer Lithium-ion batteries, compared with traditional lithium-ion batteries, the battery does not liquefy, does not explode. 360 Children watch support life waterproof, can prevent children wash hands, play the process of splashing water, but do not recommend washing and soaking. 360 Children's watches can work for at least half an hour at-40 ℃ and 75 ℃, but for the safety of their children, they should stay away from fire and extreme temperature conditions.

Tishen revealed that 360 children's watches have been linked with Taikang life, the introduction of a value of 50000 yuan "child accident insurance" for children with accidental injuries, abrasions, fractures and other circumstances to pay. (Evan)
