Telephone watches, a new communication tool which integrates watches, calls, positioning and other functions, have been sought after by many young parents in recent years. At present, there are many brands of telephone watches aiming at children's safe positioning, and their functions are quite complete. PCBA plays a tremendous role in smart watches. At the same time, the market prospects are considerable. The built-in PCB can achieve the following functions:
Telephone watch function 1: call function
Usually you need to buy a SIM card and put it on your watch, and the SIM card also needs to open the data flow function, which depends on the requirements of each brand. Users bind their watches through mobile app, set up their watches'address book, so that the watches and mobile phones can call each other. Usually watches have built-in speakers, the voice is very clear, children wear on the wrist when talking, basically do not need to be close to the ear to talk normally. In addition, when a watch contact is set up, calls from strangers are generally rejected, which also prevents children from receiving calls from bad people.
Telephone watch function 2: one-click call for help
When a child encounters an emergency, he can press the call button. At this time, the watch will call the emergency contact immediately, and send a short message and an APP notification to tell parents that the parents will receive the phone at the first time, and the latest location of the child can be seen on the APP map.
Telephone watch function three: positioning function
At present, the mainstream watches will use the GPS of the United States, and some brands use the Beidou positioning system of China. No matter which positioning system is used, the positioning errors at present are not very different and basically accurate. However, this positioning system can only be used outdoors, but can not be used indoors, so some brands can solve the problem of indoor positioning by using SuperLBSTM positioning combined with parents'mobile phone WIFI.
