[0008] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] This utility model provides, for example Figure 1 The illustrated low-power real-time network positioning walkie-talkie includes a low-power 2.4GHz network real-time networking find my circuit. The low-power 2.4GHz network real-time networking find my circuit includes an MCU main control chip U4, with a 2.4GHz chip U5 connected to the right end of the MCU main control chip U4. A 26MHz crystal oscillator X1 and an accelerometer U7 are respectively connected to the left and right sides of the lower end of the 2.4GHz chip U5. An AMP sound gain chip U2 is connected to the upper end of the 2.4GHz chip U5. A speaker SPK is connected to the right end of the AMP sound gain chip U2. Both the MCU main control chip U4 and the 2.4GHz chip U5 are connected to a 3V power supply.

[0011] The MCU main control chip U4 is used to control the working mode and signal processing of the 2.4GHz chip U5. The 26MHz crystal oscillator X1 can provide clock signals. The accelerometer U7 is used to detect the motion status information of the device. The AMP sound gain chip U2 amplifies the audio signal and drives the speaker SPK to output clear voice. The 3V power supply is used to power the low-power 2.4GHz network real-time networking find my circuit system.

[0012] In some specific embodiments of this utility model, the left end of the MCU main control chip U4 is connected to the display LCD, and the lower end of the MCU main control chip U4 is connected to the light-emitting diode LED and the switch button KEY.

[0013] The LCD screen can display positioning symbols, and the LEDs serve as status indicators.

[0014] The working principle is as follows: The entire circuit is divided into a walkie-talkie section and a low-power 2.4GHz network real-time networking Find My circuit section. After the switch button KEY is operated, the MCU main control chip U4 receives the switch information and controls whether the 2.4GHz chip U5 is turned on or off. After the low-power 2.4GHz networking module is turned on, the positioning function is realized. At this time, a positioning symbol will be displayed on the walkie-talkie's LCD screen to indicate that the walkie-talkie positioning system has been turned on. The device can be added using the Find My mobile app. After successful addition, the real-time location information of the walkie-talkie can be viewed. The positioning system uses Find My self-organizing network technology to provide positioning function for the product. The Find My application protocol can realize positioning function even when the product itself does not have GPS. If the product and the app are offline, the product can still be located by connecting to the network through the Find My protocol of surrounding devices with iOS and Android, and then using Apple Cloud or Google Cloud. In addition, the AMP sound gain chip U2 can play sound prompts when searching for the walkie-talkie to facilitate the search.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
