In the embodiment, the reminding method is applied to a smart bracelet, and the smart bracelet is provided with a laser emitter, and by transmitting laser light and receiving the laser, the distance information with the target object can be detected, and the smart bracelet is on the smart bracelet. A sensor is further disposed to detect motion information of the smart bracelet, and according to the distance information and the motion information, it can be determined whether the positional relationship between the smart bracelet wearer and the target object exceeds a safety threshold, and after the safety threshold is exceeded, Proactively send reminders to remind users to slow down or change direction. It can be understood that the reminding method can be applied to a blind person or a car owner, for example, when the blind person walks, reminding to avoid obstacles; and when the owner is braking, reminding the distance from the preceding vehicle. The reminding method includes the following steps S101-S104.

[0081] In step S101, distance information with the target object in the target direction is detected.

Specifically, the distance information of the target object in the target direction may be detected by the laser transmitter. In this embodiment, the target direction may be selected by the user, or may be advanced according to the forward direction of the user. The direction is set to the target direction. For example, if the user is blind, the user is detected in the forward direction when the user is not in the process; if the user is the car owner, the vehicle is in the vehicle, and the forward direction of the vehicle is detected. The target object can be other people or vehicles, or it can be a fixed building. In other embodiments, since the target object may also move, the distance f π can be further determined by multiple measurements.

[0083] In step S102, motion information of the smart bracelet is acquired.

[0084] Specifically, the motion information of the smart bracelet is acquired according to the sensor, where the motion information includes speed information of the smart bracelet.

[0085] In step S103, a positional relationship between the smart bracelet and the target object is calculated according to the motion information and the distance information. [0086] Specifically, the positional relationship is calculated according to the motion information and the distance information. In the embodiment, the positional relationship includes a speed difference and a distance between the two, wherein the relationship between the two can be seen from the positional relationship. Run the trajectory, you can see whether the two will collide or merge. In other embodiments, the safety distance between the two can be calculated based on the positional relationship.

[0087] In step S104, when the location relationship exceeds a security threshold, the smart bracelet is controlled to issue a reminder.

[0088] Specifically, it may be determined whether the distance between the two is less than a safety distance, and according to the determination result, it is determined whether the positional relationship exceeds a safety threshold. After the safety threshold is exceeded, the control smart bracelet sends a reminder to remind the user, wherein, since the situation is relatively urgent, the preferred reminding manner is a vibration reminder and a voice reminder to ensure that the user hears or feels the reminder.

[0089] As described above, the reminding method in the embodiment of the present invention detects the distance information from the target object in the target direction, and calculates the positional relationship with the target object according to the motion information of the smart bracelet, and the distance between the two is too close. A reminder is issued to remind the smartphone wearer to slow down or change direction, thereby avoiding collision with other objects, providing reference for the user's travel, improving the user experience, and expanding the use range of the smart bracelet.

[0095] In step S203, a first distance from the target object in the target direction is calculated.

[0096] Specifically, the first distance from the target object in the target direction is calculated according to the inter-turn difference and the speed of light.

[0097] In step S204, after waiting for the preset inter-segment, the laser emitter is controlled to emit and receive laser light, and the second distance from the target object in the target direction is calculated. [0098] Specifically, since both the smart bracelet wearer and the target object may be in a moving state, for the accuracy of the result, after waiting for the preset inter-segment, the distance measuring operation is performed here to obtain the second distance. It can be understood that, since the motion is not uniform, the measurement may be performed multiple times, and the embodiment is not limited thereto.

[0099] In step S205, acceleration information in the horizontal direction of the smart bracelet is acquired.

[0100] Specifically, the acceleration information in the horizontal direction of the smart bracelet is acquired by a sensor.

[0101] In step S206, speed information of the smart bracelet is calculated according to the acceleration information.

[0102] Specifically, the speed information of the smart bracelet is calculated according to the acceleration information. In other embodiments, the steps S205-S206 can be implemented by using a global positioning system, and the embodiment of the present invention is not limited thereto.

[0103] In step S207, the speed information of the target object is calculated according to the speed information of the smart bracelet and the first distance and the second distance.

[0104] Specifically, according to the speed information of the smart bracelet, the distance information between the two and the preset interval, the speed information of the target object can be calculated.

[0105] In step S208, the positional relationship between the two is calculated based on the speed information of the smart bracelet and the speed information of the target object.

[0106] Specifically, after calculating the speed information of the two, according to the distance between the two, the positional relationship between the two may be calculated, wherein the positional relationship reveals a change trend of the position of the two, the positional relationship Including speed difference, real distance and confluence.

[0107] In step S209, the safety distances of the two are calculated based on the positional relationship.

[0108] Specifically, based on the calculated positional relationship and the speed information of the two, an appropriate safety distance between the two is calculated.

[0109] In step S210, when the actual distance is less than the safety distance 吋, it is confirmed that the positional relationship exceeds a safety threshold.

[0110] Specifically, when the current implementation distance is less than the safety distance 吋, the distance may be considered too close, and there is a safety hazard

, this confirms that the location relationship exceeds the security threshold.

[0111] In step S211, a reminder instruction is generated, where the reminder instruction includes: a voice reminder and a vibration reminder.

[0112] Specifically, when the location relationship exceeds the security threshold, a reminder instruction is generated. Among them, because of this situation More urgent, the preferred reminder mode is a vibrating reminder and a voice reminder to ensure that the user hears or feels the reminder.

[0113] In step S212, the smart bracelet is controlled to issue a reminder according to the reminding instruction.

[0114] Specifically, the smart bracelet is controlled to issue a reminder according to the reminding instruction, wherein the reminder includes a voice reminder or a vibration reminder, thereby reminding the user to pay attention to safety.

[0115] As described above, the reminding method in the embodiment of the present invention detects the distance information from the target object in the target direction, and calculates the positional relationship with the target object according to the motion information of the smart bracelet, and the distance between the two is too close. A reminder is issued to remind the smartphone wearer to slow down or change direction, thereby avoiding collision with other objects, providing reference for the user's travel, improving the user experience, and expanding the use range of the smart bracelet.
