An alarm prompting method, a terminal, and a computer readable medium provided by the present application are further described below.

Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of an alarm prompting method provided by an embodiment of the present application. As shown in FIG. 2, the alarm prompting method includes the steps 201-204, wherein:

201. The first terminal establishes a wireless connection with the second terminal.

It should be noted that, for the first terminal, the process of establishing a wireless connection may be divided into the following steps: receiving a wireless connection module open command of the first terminal; opening a wireless connection module of the first terminal, and using the wireless of the first terminal The connection module sends a connection establishment request to the second terminal; receives a feedback message for successfully establishing the connection, and establishes a connection with the second terminal.

For the second terminal, the process of establishing a wireless connection may be divided into the following steps: receiving a wireless connection module open command of the second terminal; opening a wireless connection module of the second terminal, and receiving a connection establishment request message of the first terminal; A terminal sends a feedback message for successfully establishing a connection, and establishes a connection with the first terminal.

Similarly, the second terminal may initiate a connection establishment request to the first terminal, and the interaction process is similar to the foregoing steps, and details are not described herein again.

The wireless connection can be implemented by a mobile communication system, a wireless local loop system, a cordless telephone system, a mobile satellite access system, or a wireless local area network.

202. The first terminal detects, at a preset time interval, a signal power value used by the first terminal and the second terminal to perform a wireless connection.

It should be noted that the signal power value used by the first terminal and the second terminal for wireless connection may be the transmit signal power value of the first terminal or the received signal power value of the first terminal for the first terminal.

203. The first terminal determines whether the signal power values detected in the first preset time are all greater than the first preset power value.

The first preset power value is a power corresponding to the first preset distance determined according to a correspondence between the pre-stored power and the distance. For example, the correspondence between the transmit power and the distance of the pre-stored first terminal is as shown in Table 1. If the first preset distance is set to 10 meters, the corresponding first preset power is 40 millimeters. watt.

Table 1

距离(米)Distance (m)	55	7.17.1	1010	14.114.1
发射信号功率(毫瓦)Transmit signal power (milliwatts)	1010	2020	4040	8080

The first preset distance is a security distance set by the user of the first terminal according to requirements, and the second terminal user is considered to be safe within a first preset distance from the first terminal user. If you set the distance, you may think that danger or loss may occur.

For example, different preset distances can be set according to different environments. In a complex environment with many people and more vehicles, a shorter preset distance, such as 10 meters, can be set; in a quieter and less crowded environment, a longer preset distance, such as 15 meters or 20 meters, can be set.

According to step 202, if the detected signal power value of the first terminal is detected, the first preset power is determined according to the corresponding relationship between the pre-stored transmit signal power and the distance; if the received signal power value of the first terminal is detected, , determining the first pre-correlation according to the pre-stored correspondence between the received signal power and the distance Set the power.

For example, the corresponding relationship between the received signal power value of the first terminal and the distance is as shown in Table 2. If the received signal power value of the first terminal is detected, and the first preset distance is 10 meters, the first preset The power is 12 milliwatts.

Table 2

距离(米)Distance (m)	55	7.17.1	1010	14.114.1
接收信号功率(毫瓦)Received signal power (milliwatts)	33	66	1212	24twenty four

It should be further noted that, by determining whether the signal power values detected in the first preset time are greater than the first preset power value, the second terminal user can be prevented from being moved back and forth at the edge of the first preset distance. The trouble caused by multiple alarms of a terminal.

For example, if the second terminal user arrives at a certain distance from the first terminal user at a certain moment, the alarm prompt is not immediately sent to the first terminal, but the first detection is performed every 30 seconds. The value of the transmit power value or the received power value of the terminal, if the detected transmit power value or the received power value is greater than the corresponding first preset power value within 2 minutes, an alarm prompt is sent to the first terminal.

204. If yes, the first terminal outputs an alarm prompt.

In the embodiment of the present invention, the distance between the first terminal user and the second terminal user is indirectly determined by determining the transmit signal power value or the received signal power value between the first terminal and the second terminal. Therefore, when the distance between the second terminal user and the first terminal user exceeds a preset security value, an alarm prompt can be sent to the first terminal in time to prevent the second terminal user from being dangerous or losing the second terminal user.

Optionally, before the first terminal outputs the alarm prompt, the first terminal may determine whether the signal power value detected in the second preset time gradually increases with time, and if yes, execute step 204.

It should be noted that if it is determined that the signal power value detected in the second preset time gradually increases with time, it indicates that the second terminal user's activity range not only exceeds the first preset distance, but also the distance is first. The distance of the terminal is getting farther and farther, and an alarm prompt is sent to the first terminal user.

Through the embodiment of the present invention, the distance between the second terminal user and the first terminal user can be determined, not only has exceeded the preset safety distance, but the distance from the first terminal user is gradually increasing. It can be accurately determined that in this case, it is necessary to issue an alarm prompt to the first terminal in time to detect the abnormality in time and avoid losing the first terminal user.

Optionally, after the first terminal establishes a wireless connection with the second terminal, the second terminal detects, by using the preset time interval, a signal power value used by the second terminal to perform wireless connection with the first terminal.

Similarly, the signal power value used by the second terminal to perform wireless connection with the first terminal may be a transmit signal power value of the second terminal or a received signal power value of the second terminal.

Correspondingly, the second terminal determines whether the signal power values detected in the first preset time are all greater than the third preset power value. The third preset power value is the power corresponding to the first preset distance determined according to the correspondence between the pre-stored power and the distance in the second terminal.

The first preset distance is sent by the first terminal to the second terminal. If the signal power value used for the wireless connection is the transmit signal power value of the second terminal, the correspondence between the pre-stored power and the distance is the correspondence between the transmit signal power value and the distance of the second terminal; The signal power value used for the connection is the received signal power value of the second terminal, and the correspondence between the pre-stored power and the distance is the correspondence between the received signal power value of the second terminal and the distance.

Correspondingly, if yes, the second terminal outputs an alarm prompt.

According to the embodiment of the present invention, whether the distance between the second terminal and the first terminal exceeds is determined by comparing the transmit signal power value of the second terminal or the received signal power value of the second terminal with the third preset power value. The first preset distance, if yes, the second terminal outputs an alarm prompt. In this way, when the distance between the second terminal and the first terminal exceeds a preset safety distance, the second terminal user is promptly reminded to avoid the situation that the first terminal user is lost.

Optionally, as shown in FIG. 3, the alarm prompting method may further include the content of steps 305-308. The specific implementation manners of steps 301-304 refer to the contents of steps 201-204 in Embodiment 2, and details are not described herein again. among them:

305. The first terminal determines whether the detected signal power value reaches a second preset power value.

The second preset power value is a maximum power value in a correspondence between a pre-stored power and a distance in the first terminal. Considering that the transmit power of the first terminal and the second terminal cannot be increased indefinitely, when the maximum power value in the correspondence between the pre-stored power and the distance is reached, the first terminal and the second terminal The connection at the end may be broken.

306. If yes, the first terminal detects whether the wireless signal sent by the second terminal is received in the third preset time.

The third terminal detects whether the first terminal receives the wireless signal sent by the second terminal, and the purpose is to determine whether the connection between the first terminal and the second terminal has been disconnected.

307. If the wireless signal sent by the second terminal is not received within the third preset time, send the first indication message to the second terminal.

The first indication message is used to instruct the second terminal to send current location information and recording information of the second terminal to the first terminal. If the first terminal does not receive the wireless signal sent by the second terminal in the third preset time, the connection between the first terminal and the second terminal is considered to be disconnected, and the reason for the disconnection is not because the user manually disconnects, but Because the second terminal is getting farther and farther from the first terminal, the disconnection occurs.

After the wireless connection between the first terminal and the second terminal is disconnected, the standby connection mode may be opened for subsequent data transmission. For example, the first terminal can communicate with the second terminal by using a data traffic manner such as WiFi, GPRS, 3G, or 4G. The second terminal can communicate with the first terminal by using data traffic such as GPRS, 3G or 4G.

308. The second terminal sends current location information and recording information of the second terminal to the first terminal.

It should be noted that the information interaction between the first terminal and the second terminal is performed by using a backup connection manner. After receiving the first indication message sent by the first terminal, the second terminal acquires the current location information of the second terminal, starts the recording module, records the recording information of the preset duration, and sends the location information and the recording information to the first terminal. . Sending the current location information of the second terminal and the recording information of the preset duration to the first terminal may help the first terminal user to quickly know the current location and state of the second terminal user, so as to quickly find the user of the second terminal.

According to the embodiment of the present invention, after detecting that the first terminal and the second terminal are disconnected, the standby connection mode is started; the location information and the recording information of the second terminal are obtained in time, and sent to the first terminal; After receiving the alarm prompt, an end user can confirm the location information of the second terminal user and judge the state of the second terminal user through the recorded information, thereby avoiding loss with the second terminal user.

Optionally, as shown in FIG. 3, the alarm prompting method may further include the content of steps 309-312, where:

309. The first terminal outputs an alarm prompt confirmation box.

The alarm prompt confirmation box is used by the first terminal to confirm whether the user of the first terminal has viewed the alarm prompt output by the first terminal.

310. The first terminal sends an alarm prompt to the third terminal.

It should be noted that, after the first terminal outputs the alarm prompt, the first terminal does not receive the alarm prompt confirmation command within the fourth preset time, the first terminal sends an alarm prompt to the third terminal.

Optionally, the foregoing third terminal is determined by the second terminal according to the connection record. The second terminal uses the terminal device having the highest number of connections with the second terminal except the first terminal as the third terminal. Before the first terminal sends an alarm prompt to the third terminal, the first terminal may send a fourth indication message to the second terminal, where the fourth indication message is used to instruct the second terminal to send the information of the third terminal to the first terminal.

For example, if the first terminal is a child's mobile phone, the second terminal is a wearable device on the child; after determining that the distance between the child's wearable device and the child's mother's mobile phone exceeds the first preset distance, The first terminal sends an alarm prompt; but because the surrounding environment is noisy or the mother does not check the mobile phone and does not confirm the alarm prompt; the child's mother's mobile phone sends a fourth indication message to the child's wearable device to request the information of the third terminal; The wearable device queries the historical connection record and finds that the child's father's mobile phone is the highest number of connections, except for the child's mother's mobile phone. The child's father's mobile phone related information is fed back to the child's mother's mobile phone; After the feedback information, an alert message is sent to the child's mobile phone.

Alternatively, the third terminal may be a terminal preset by the first terminal. For example, the first terminal is a mobile phone of a child's mother. The first terminal may receive a setting instruction for setting a third terminal, and the setting instruction carries a mobile phone identifier of the child dad; the first terminal sets the mobile phone of the child dad as the third terminal according to the setting instruction.

311. The first terminal sends a second indication message to the second terminal.

The second indication message is used to instruct the second terminal to send current location information and recording information of the second terminal to the third terminal.

312. The second terminal sends current location information and recording information of the second terminal to the third terminal.

After the second terminal receives the second indication message sent by the first terminal, the second terminal acquires the current location information of the second terminal and starts the recording module, and the recording is preset. Long recording information, and the location information and recording information are sent to the third terminal.

It should be noted that the content of step 310 only sends an alarm prompt to the third terminal, and only the user of the third terminal can know that the user of the second terminal may be lost or dangerous, but cannot know the accurate information about the second terminal. . And sending the current location information and the recording information to the third terminal, the effective information can be provided to help the user of the third terminal to confirm the location information and the current state of the second terminal user.

According to the embodiment of the present invention, the first terminal determines whether the first terminal user has viewed the alarm prompt message by detecting whether the alarm prompt confirmation command is received; if not, issuing an alarm prompt to the third terminal, and indicating the second terminal Sending current location information and recording information to the third terminal; ensuring that the third terminal can receive the alarm prompt information in time when the first terminal user does not promptly view the alarm prompt; improving the reliability of the alarm prompt and avoiding the second terminal The user and the first terminal user are lost.

Optionally, as shown in FIG. 3, the alarm prompting method may further include the content of steps 313-314, wherein:

313. The first terminal sends a third indication message to the second terminal.

The third indication message is used to instruct the second terminal to acquire the average moving speed of the second terminal and send the average mobile terminal to the first terminal.

314. The second terminal acquires a current average moving speed and sends the current moving speed to the first terminal.

It is to be noted that, after receiving the average moving speed sent by the second terminal, if the first terminal determines that the average moving speed of the second terminal is greater than the first preset speed, the first terminal sends an alarm prompt to the third terminal. step.

The determining whether the average moving speed of the first terminal exceeds the first preset speed may determine whether an abnormal situation occurs in the second terminal user.

For example, if the second terminal is a wearable device for a child, the first preset speed is 1.5 m/s (equivalent to the speed of an adult walking); when traveling or shopping, the walking speed of the child is generally not If the walking speed exceeds the adult speed, if the first preset speed is exceeded, the child may be taken away or taken to the car to judge that danger may occur at this time.

Optionally, the third indication message is further used to indicate that the second terminal acquires the second terminal in the preset time. The average heart rate of the user, and the average heart rate is sent to the first terminal. After receiving the average heart rate, the first terminal determines whether it is within the pre-stored normal heart rate range, and if not, sends an alarm prompt to the third terminal.

According to the embodiment of the present invention, the first terminal may send an indication message to the second terminal, to indicate that the second terminal feeds back the current average moving speed or the average heart rate to the first terminal; The average moving speed or the average heart rate is indirectly determined whether the second terminal user has an abnormal situation; an alarm prompt is issued to the third terminal user in time to prevent the first terminal user from being lost or an accident.
