[0026] The embodiment of the present invention provides a system for locating and guiding people home. Figure 1-3 As shown, it is used to locate and assist mentally retarded people and unconscious persons to return home, including a tracker 1, a mobile receiving terminal 2 and a locator 3. The tracker 1 is placed on the user, the mobile receiving terminal 2 is carried by the assistant, and the locator 3 is placed at home. When the tracker 1 exceeds the preset range, it will issue a reminder to the user and then send the information to the mobile receiving terminal 2 and the locator 3. After the mobile receiving terminal 2 receives the user's location information, it is convenient to find the user. After the locator 3 receives the information from the tracker 1, it feeds back to the tracker 1 to assist the user to return home.

[0027] Further, such as Figure 4 As shown, the tracker 1 has a shell 11 outside, a speaker 16 is embedded on the upper side of the inner cavity of the shell 11, a vibrator 17 is provided on the lower side of the inner cavity of the shell 11, a GPS antenna 12 is provided outside the shell 11, and an integrated circuit board 14 and a power module 15 are provided in the inner cavity of the shell 11;

[0028] The integrated circuit board 14 integrates a signal control chip 141, a GPS chip 142, a boost chip, a GPS power supply chip, a speaker 16 power supply chip, and a vibrator 17 power supply chip. Figure 2 As shown, the circuit connection relationship between the signal control chip 141, the GPS chip 142, the boost chip, the GPS power supply chip, the speaker 16 power supply chip, the vibrator 17 power supply chip and the GPS antenna 12, the GPS chip 142, the speaker 16, and the vibrator 17 is as follows:

[0029] The power module 15 is connected to the electrical input end of the boost chip, and the electrical output end of the boost chip is respectively connected to the electrical input ends of the GPS power supply chip, the speaker 16 power supply chip, and the vibrator 17 power supply chip;

[0030] The electrical output terminal of the GPS power supply chip is connected to the electrical input terminal of the GPS chip 142, and the signal interface of the GPS chip 142 is bidirectionally connected to the signal interface of the signal control chip 141, the transceiver end of the GPS chip 142 is connected to the GPS antenna 12, and the electrical output terminal of the signal control chip 141 is connected to the electrical input terminal of the GPS power supply chip;

[0031] The electrical output terminal of the vibrator 17 power supply chip is connected to the electrical output terminal of the vibrator 17, the electrical output terminal of the signal control chip 141 is connected to the electrical input terminal of the vibrator 17, and the signal terminal of the vibrator 17 is bidirectionally connected to the signal interface of the signal control chip 141;

[0033] The boost chip is the ETA1061S2G static low-current chip with low static current, which can meet the power supply requirements of the entire system. The GPS power supply chip is the WL2836D22-4 static low-current chip with extremely low static current, which is suitable for long-term power supply requirements of vibration sensors and can meet the current requirements of power saving mode.

[0034] The mobile receiving terminal 2 can be replaced by a mobile phone, which receives the coordinate position of the user through the corresponding APP on the mobile phone, and assists family members to quickly find the user.

[0035] In the present embodiment, GPS positioning tracking is adopted, and the GPS antenna 12 in the tracker 1 receives and sends GPS information to the satellite, and the satellite sends the user's GPS information to the mobile receiving terminal 2.

[0036] In addition, other transmission methods can also be used. For example, the locator 3 placed in the user's home uses similar radio frequency tracking technology, which is a reflective type. It transmits a radio wave of a specific frequency to the tracker 1. The single channel in the tracker 1 will reflect a specific radio wave, which locates the user's coordinates like a radar. The relevant positioning information is sent by the locator 3 to the mobile receiving terminal 2 of friends and relatives; further, a high-power radio wave transmitter can be installed in the tracker 1 to generate radio waves to the locator 3 at home.

[0037] Furthermore, the tracker 1 also includes a camera 18 , which is worn on a headgear 19 and is used to capture the environment around the user and transmit it to the mobile receiving terminal 2 .

[0038] Specifically, Figure 4 As shown, the housing 11 is further provided with a cord buckle 111 , on which a strap 112 is fastened, and the housing 11 is fastened around the waist via the strap 112 .

[0039] Furthermore, the signal control chip 141 is an L630C control chip, and the L630C control chip is a small-size, 45-pin LCC package module, integrating UART, I2C, ADC, and GPIO interfaces. L630C can support a wide frequency range of radio frequency, supporting frequency bands of B3, B5, B8, B20, and B28. It supports three modes: in-band, protection band, or independent carrier, supports PSM and eDRX modes, and integrates 32Mb of NORFLASH (flash memory) and 32Mb of psRAM (memory).

[0040] Furthermore, the PS chip is a HD2028 dual-mode positioning chip, which integrates URAT, IIC, and SPI interfaces and supports receiving BDSB11, GPSL1CASBAS satellite signals. HD2028 is a cost-effective dual-mode positioning chip with low cost, low power consumption, high signal-to-price ratio, and high positioning accuracy.

[0041] Working principle, when the personnel positioning and guidance home system is used, such as Figure 3 The flow chart is shown as follows:

[0042] Step 1: Set the tracker 1 out of range in the locator 3. Figure 1 As shown, within a radius of 500 meters, the tracker 1 does not activate the auxiliary function.

[0043] Step 2: When the user, i.e. the tracker 1, goes beyond the preset range of the locator 3, the GPS chip 142 detects that it has gone beyond the preset range and sends a signal to the signal control chip 141. The signal control chip 141 sends an indication signal to the speaker 16 and the vibrator 17.

[0044] Step 3: The speaker 16 emits a voice prompt, such as "You are more than 500 meters away from home, please go home", and the vibrator 17 starts vibrating to remind the user.

[0045] Step 4: After a certain time reminder, the GPS chip 142 sends the user's coordinate information and other GPS information to the mobile receiving terminal 2 and the positioning device 3 installed at home. The positioning device 3 feeds back the home coordinate position to the GPS chip 142.

[0046] Step 5: The GPS chip 142 specifies a navigation route for returning home and transmits it to the signal control chip 141, which then broadcasts the navigation route through the speaker 16 to assist the user in navigating home.

[0047] In summary

[0048] The personnel positioning and guidance homecoming system includes a tracker 1, a mobile receiving terminal 2 and a locator 3. After the tracker 1 exceeds a preset distance from the locator 3, the signal control chip 141 in the tracker 1 transmits a signal to the speaker 16 and the vibrator 17 to remind the user, and then sends a signal to the mobile receiving terminal 2 and the locator 3. The speaker 16 assists the user to return home through voice, and the family members can quickly find the user through the mobile receiving terminal 2.
