Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

Referring to Fig. 1, it is the main flow of an embodiment of the emergency help-seeking method of the present invention, which is applied between a help-seeking terminal device 1 and an assistance terminal device 2; and the help-seeking terminal device 1 and the assistance terminal device 2 can It is but not limited to portable or wearable electronic devices with positioning functions such as mountaineering track recorders, bicycle watches or smart phones.

And as shown in FIG. 2 , the help-seeking device 1 mainly includes at least one motion sensor 11, a storage unit 12, a positioning module 13, a first low-power wireless communication module 14 and is electrically connected to the aforementioned components A processing unit 1, the motion sensor 11 mainly detects the motion and/or position status of the help-calling device 1 and outputs a corresponding sensing information, and in this embodiment, the at least one motion sensor The device 11 may be, but not limited to, at least one of an accelerometer, an altimeter, and the like. A plurality of authentication codes are pre-stored in the storage unit 12 , and each of the authentication codes corresponds to a communicable application program, such as an application program that can interpret the message content sent by the help-calling device 1 . The positioning module 13 may be but not limited to a Global Positioning System (GPS) module. And in this embodiment, the first low-power wireless communication module 14 adopts but is not limited to a low-power Bluetooth 5.0 module (generally referred to as Bluetooth 5.0 or BLE5.0 module), and one of the main features of Bluetooth 5.0 is While maintaining low power consumption (Low-Energy), it can operate in long-distance transmission mode (Bluetooth Long Range, BLR or Coded PHY) at a lower data transmission rate (125kbps). The processing unit 15 can be a processor, a microprocessor or a microcontroller, etc., and it can execute a computer-readable recording medium, such as a software program stored in the storage unit 12 of this embodiment, such as An emergency help application program to automatically and timely send out help messages.

The assistant device 2 mainly includes a storage unit 21 , a second low-power wireless communication module 22 and a processing unit 23 electrically connected to the aforementioned components. A software program is stored in the storage unit 21 , such as an emergency aid application program, which can receive help messages from the outside in a timely manner and can interpret and respond to the help messages. And in this embodiment, the second low-power wireless communication module 22 also adopts but is not limited to the low-power Bluetooth 5.0 module and can operate in the long-distance transmission mode with a lower data transmission rate. Other low-power and long-distance transmission methods include at least narrow-band Internet of Things NB-IoT (Narrowband Internet of Things) and long-distance low-power network LoRaWAN (long range wide-area network). The former needs to pass through the base station, and the latter According to the current technical situation, the volume is slightly larger, which is not convenient for the use of handheld devices, but with the two characteristics of low power consumption and long distance, the above two transmission methods can also be used to achieve the purpose of the present invention.

Thus, when a user is active in the mountains or in the wilderness and turns on the help-seeking device 1, the processing unit 15 of the help-seeking device 1 will automatically load and execute the emergency help-seeking application program from the storage unit 12 , and turn on the motion sensor 11, the positioning module 13 and the first low-power wireless communication module 14 and perform the following actions. As shown in step S11 of FIG. 1 , the processing unit 15 of the help-seeking device 1 will judge whether an emergency event occurs according to the sensing information transmitted (provided) from the motion sensor 11 at any time, such as the processing unit 15 According to the sensing information, it is judged that the unexpected large-scale position change of the device exceeds a threshold value and/or the duration of the unexpected large-scale position change exceeds a preset value, for example, the accelerometer (or gyroscope) If a large number of irregular values are sensed within a period of time and/or the altimeter detects a rapidly changing depressurization (pressure value) representing a sudden and sharp drop in height and the duration reaches the preset value, the processing unit 15 determines that there is an emergency When an event occurs, record an occurrence time (current time) and a current height (if detected, for example, the motion sensor 11 is an altimeter) of the emergency event, and require the positioning module 13 to provide the current Then, the processing unit 15 executes step S12 of FIG. 1, and the processing unit 15 outputs an inquiry message, such as displaying the inquiry message or outputting the inquiry message by voice, asking the user whether to cancel the emergency event, in order to avoid misjudgment.

At this time, if the user does not want to activate the emergency help function, he can reply the inquiry message manually or by voice, then the processing unit 15 will cancel and ignore the emergency event and return to step S11 after receiving the reply message from the user; Conversely, when the processing unit 15 determines that the user does not reply within a preset time (for example, 30 seconds or 1 minute) after the inquiry message is sent, it is assumed that the emergency event does occur, and step S13 in FIG. 1 is executed. In addition, the content of the inquiry message can also be changed to whether there is an emergency? Has the search and rescue been completed in the emergency? And the user or the searcher can input information and send it. It is worth mentioning that the above step S12 is not necessary and may be omitted depending on actual application requirements.

In step S13, the processing unit 15 makes the first low-power wireless communication module 14 operate in the long-distance communication mode and switches from the original high-security pairing mode to a low-security pairing mode, such as the just Work mode or no authentication mode, and step S14 as shown in Figure 1, transmit (broadcast) a pairing request, so that the first low-power wireless communication module 14 can be covered with the first low-power wireless communication module 14 The assistant device 2 within a long-distance communication range (for example, a radius of 1 km) is paired and established a connection. Wherein, the pairing request usually includes a device identification code of the help-calling device 1, and the device identification code implies the characteristics or functions of the device, for example, the specific bit codes in the device identification code represent the help-calling terminal The device 1 is an electronic device with a help function.

Therefore, when the second low-power wireless communication module 22 of the assistant device 2 within the long-distance communication range covered by the first low-power wireless communication module 14 receives the pairing request, as shown in FIG. Step S21 of 1, the processing unit 23 of the assistance device 2 first judges whether the assistance-request device 1 is a priority pairing device according to the device identification code included in the pairing request, for example, judging the specific When several bit codes represent that the help-seeking terminal device 1 is an electronic device with a help-seeking function, the processing unit 23 of the assistance-calling terminal device 2 determines that the help-calling terminal device 1 is a device that needs to be paired first, and the second lowest The power consumption wireless communication module 22 operates in the long-distance transmission (Bluetooth Long Range, BLR) mode and the low security pairing mode, and is preferentially paired with the first low power consumption wireless communication module 14 of the help-seeking device 1 , and as shown in step S22 of FIG. 1 , return an acceptance pairing message to the first low-power wireless communication module 14, and the processing unit 23 loads and executes the emergency assistance application program stored in the storage unit 21 , to be ready to receive messages from the help-calling device 1 at any time.

Therefore, when the first low-power wireless communication module 14 receives the pairing acceptance message, the help-calling device 1 and the helping-side device 2 establish a connection, and can start to exchange messages. It is worth mentioning that the above-mentioned step S21 can also be omitted, that is, the assistant device 2 accepts the pairing request and returns the pairing acceptance message once it receives the pairing request when no device is paired with it, and There is no need to confirm the device ID included in the pairing request.

Furthermore, in order to confirm that the paired assistance terminal device 1 has a tool capable of interpreting the content of the message sent by the assistance terminal device 1, such as the above-mentioned emergency assistance application program, the assistance terminal device 1 starts to send a help request message to the assistance terminal device 2. Before the assistance terminal device 2, as shown in step S15 of FIG. Second, the low-power wireless communication module 22 receives the authentication request and provides it to the processing unit 23. At this time, if the processing unit 23 can interpret the authentication request, it means that the emergency assistance application program can interpret the help terminal The message sent by the device 1 is as shown in step S23 of FIG. 1 , the processing unit 23 returns an authentication code representing the emergency assistance application program to the help-calling device 1 through the second low-power wireless communication module 22 .

Therefore, the first low-power wireless communication module 14 of the help-end device 1 receives the authentication code and provides it to the processing unit 15, and then as shown in step S16 of FIG. Whether the authentication code provided is the same as one of the authentication codes stored in the storage unit 12, if so, it is determined that the assistance terminal device 2 can interpret the message to be sent, and confirm that the assistance terminal device 2 is authenticated, And proceed to step S17; On the contrary, if the processing unit 15 judges that the authentication code provided by the assistant device 2 does not exist in the authentication codes stored in the storage unit 12, or the assistant device 2 has not returned Pass the authentication code, that is, determine that the assistance terminal device 2 cannot interpret the message to be transmitted, then execute step S18 in Figure 1, so that the first low-power wireless communication module 14 is interrupted from the second low-power wireless communication module 14 The communication module 22 is connected, and steps S13-S16 are re-executed to re-find the next assistance device 2 that can communicate with it (interpret its message).

In step S17, the processing unit 15 of the help-seeking device 1 generates a help message, the help message at least includes the occurrence time of the emergency event, the height (if any) and the location module 13 provided position information, then, as in step S19, the processing unit 15 transmits the help request message to the assistance device 2 through the first low-power wireless communication module 14, thereby, when the assistance device 2's second low After the power consumption wireless communication module 22 receives the help message and provides it to the processing unit 23, the processing unit 23 will be able to interpret the help message and present the help message, for example, display the help message and issue a notification or warning The ringtone is used to remind the user of the aid terminal device 2 to check the help message, so as to provide assistance or search and rescue in time; thereby, the purpose of asking for help is achieved.

In addition, before the emergency help application program of the help-seeking device 1 sends the help message, the user can also allow the user to manually input a help content in the help message, such as providing an input field for the user to manually input text or open The voice recording function allows the user to input a voice to provide further search and rescue information. In this way, when the help-seeking device 1 does not have the positioning module 13, the user can actively provide more detailed and specific search and rescue information with clear awareness.

In addition, the assistance device 2 receives the help message and confirms that the user checks the help message. For example, after the user reads the help message, the assistance device 2 will return a received message to the help device 1 The first low-power wireless communication module 14, and the help-side device 1 presents the received message from the help-side device 2, for example, by displaying the received message or sending out a notification ringtone, thereby, in the When the user of the help-side device 1 is conscious, the user knows that the help-side device 2 has received the help message.

Furthermore, the emergency assistance application program of the assistance terminal device 1 and the emergency assistance application program of the assistance terminal device 2 can also pre-define a plurality of fixed questions and their corresponding numbers, that is, give each fixed question a corresponding number. Corresponding numbers, for example, the question corresponding to number 001 is "Is it injured and unable to move?", the question corresponding to number 002 is "Do you have drinking water and food for more than one day?", etc., and the answer codes of these fixed questions, such as answer codes 1 represents "yes", and the answer code 2 represents "no" etc.; thus, when the assistance terminal device 2 needs to communicate with the user of the assistance terminal device 1 after receiving the help message, it only needs to send the contained number, For example, if a message containing number 001 is sent to the help-calling device 1, after receiving the message containing number 001, the help-calling device 1 will display the question corresponding to number 001, that is, "Is it injured and unable to move?" to the user Check, at this time, the user of the help-seeking terminal device 1 only needs to manually input "1" or "2" or voice input "yes" or "no" through the emergency help-seeking application program, and the help-seeking terminal device 1 will immediately send the Reply the message of code 1 or 2 to the aiding device 2, and then the aiding device 2 will display "Yes" or "No" for its user to check after receiving the message containing the reply code 1 or 2. This can reduce the amount of data carried in the transmitted message, making it easier for the message to be sent and successfully received by the other party.

To sum up, the help-calling device 1 and the assistance-side device 2 in the above-mentioned embodiment are equivalent to mobile base stations, and after the help-calling device 1 determines that an emergency event has occurred, by making the first low-power consumption The wireless communication module 14 operates in the long-distance transmission mode and the low-security pairing mode, so that the first low-power wireless communication module 14 can quickly pair and establish a connection with the assistant device 2 within a long-distance communication range. After going online, the help-side device 1 requires the help-side device 2 to provide an authentication code, and according to the authentication code to verify that the help-side device 2 has the ability to interpret the message sent by the help-side device 1, the help-side device 1 Send the help-seeking message to the aid-end device 2 through the first low-power wireless communication module 14, so that the aid-end device 2 interprets and presents the help-seeking message for its user to view, thereby achieving the help-end device of the present invention 1. It can automatically increase the wireless transmission distance and lower the pairing connection threshold, so as to successfully connect with the assistance terminal device 2 located farther away and automatically send the help message to the assistance terminal device 2, so as to effectively Shorten the time for search and rescue personnel to search for people in emergency events, and reduce the probability of death of people in emergency events.
