Children's Day is coming. Have you not chosen a gift for your little prince or princess? A children's smartwatch would be a good choice. As an important branch of smart wearable devices, children's smartwatches have developed rapidly in the past two years. According to IDC's "China Wearable Device Market Quarterly Tracking Report", the shipment volume of children's smartwatches in the first quarter of 2018 was 5.07 million units, a year-on-year increase of 44.6%, of which 4G product shipments reached 1.48 million units, a year-on-year increase of 422.4%.
The functions of children's smartwatches are also constantly enriched, and at the same time, they have been recognized by more and more parents. In first- and second-tier cities, children's smartwatches have almost become a must-have for children, and consumers' functional requirements for products are becoming more and more diverse. Compared with the sports and sleep monitoring on adult smartwatches, the positioning and call functions of children's watches are more rigid. 6 ways to achieve real-time positioning The basic working principle of most children's smartwatches is mainly to achieve positioning through GPS, which is the same as the principle of mobile phone positioning. Insert a phone card and realize the positioning function through signals. However, GPS is mainly used in outdoor and open areas. It is difficult to locate indoors, in underground parking lots, underground shopping malls, etc., and the error is relatively large.
After positioning through six methods of GPS+Beidou+base station+WIFI+gravity sensor+PDR, the PDR fusion method is turned on, and the positioning accuracy is significantly improved. At the same time, the strong tracking mode can be turned on to further improve the positioning accuracy. By viewing the child's daily movement trajectory on the mobile phone, you can intuitively judge the approximate location of the watch. New software and hardware design to ensure calls The call function of the children's smart watch supports anti-harassment call/message interception. Only phones with a whitelist can call and send text messages to the children's watch. The blocked calls/messages appear in the notification information. Parents can set whether to add them to the watch address book. Phone numbers that are not in the watch address book will be automatically intercepted when they call in.

In a noisy place, you may not be able to hear the other party's speech, and the answering effect is not good. Some manufacturers have made a new design, supporting an independent sound cavity system, using an original children's voice noise reduction technology, highlighting the call sound, and reducing the impact of environmental factors on call quality. Even in a noisy environment, parents can hear their children's voices. TI's children's smart watch reference design TI's integrated circuits and reference designs help engineers create small, reliable and efficient children's smart watch systems to track children's activities, run local applications, communicate with other devices, process voice commands over the Internet, play music and tell time.
