Step S1011: and if the volume value corresponding to the environment volume information is not greater than the influence volume value, outputting a voice prompt signal according to the preset set volume value.
When the volume value corresponding to the environment volume information is not larger than the influence volume value, the current environment volume is not influenced by the user to hear the navigation information, and the normal voice output is performed by the set volume value, wherein the set volume value is the value set by the user to enable the navigation to perform voice output.
Step S1012: if the volume value corresponding to the environment volume information is larger than the influence volume value, performing difference calculation according to the environment volume information and the influence volume value to determine difference volume information.
When the volume value corresponding to the environment volume information is larger than the influence volume value, the sound of the environment can influence the user to hear the navigation sound, and further analysis is needed at the moment; the volume value corresponding to the difference volume information is the volume difference value that the volume value of the surrounding environment is larger than the volume value of the voice broadcast, and the volume value corresponding to the environment volume information is subtracted by the influence volume value to determine.
Step S102: and determining a correction volume value corresponding to the difference volume information according to a preset volume matching relation.
The corrected volume value is the volume value which needs to carry out output sound adjustment on the broadcasting device of the voice prompt signal, the different difference volume information indicates that the sound which needs to be turned up is different, and the volume matching relation between the corrected volume value and the sound is determined by staff in advance according to a plurality of tests and is not repeated.
Step S103: and carrying out summation calculation according to the set volume value and the corrected volume value to determine a prompt volume value, and outputting a voice prompt signal according to the prompt volume value.
The prompting volume value is a volume value when the voice prompting signal is output and broadcast, the voice prompting signal is output by utilizing the prompting volume value to enable the voice in the surrounding environment to not cover the navigation sound by determining by adding the set volume value and the correction volume value, so that a user has better navigation experience.
Referring to fig. 2, the method further includes an acquisition step of environmental volume information, including:
step S200: and acquiring receiving volume information, receiving distance information and receiving direction information.
The volume value corresponding to the receiving volume information is the volume value of the surrounding environment received by the intelligent watch, the distance value corresponding to the receiving distance information is the distance value of the external sound source for determining the receiving volume from the watch, and the direction corresponding to the receiving direction information is the direction of the watch facing the sound source of the surrounding environment.
Step S201: and determining the receiving volume information and the sound source volume information corresponding to the receiving distance information according to the preset propagation matching relation.
The sound volume value corresponding to the sound volume information is the sound volume value output by the sound source with the largest sound received by the watch in the surrounding environment, different receiving sound volumes and receiving distances indicate different sound volumes of the sound sources, and the propagation matching relation among the three is determined by staff in advance according to multiple tests.
Step S202: and determining sound source position information according to the receiving distance information and the receiving direction information.
The position corresponding to the sound source position information is a position on the coordinate system with the watch position as the origin, as compared with the sound source of the surrounding environment.
Step S203: and calculating according to the sound source position information and the preset ear position points to determine the propagation distance information.
The ear position point is the position of the ear on the wearing side of the watch on the user, for example, if the user wears the watch on the left hand, the ear position point is the ear position on the left side of the user, and the method for determining the ear position point is described below, which is not described in detail herein; the distance value corresponding to the propagation distance information is the distance value required to be passed when the sound output by the sound source propagates to the ear of the user.
Step S204: and determining the propagation distance information and the environment volume information corresponding to the sound source volume information according to a preset diffusion matching relation.
The different sound source volume and the propagation distance lead to different volume of the sound propagated to the user's ear, namely different environmental volume information, and the diffusion matching relation among the three is determined by a staff through a plurality of experiments in advance.
Referring to fig. 3, the method further includes a step of determining the ear position point, the step including:
step S300: and establishing a detection interval with the width of a preset fixed duration on a preset time axis, and controlling the rear end point of the detection interval to coincide with the current time point.
The time axis is a coordinate axis formed by combining time points, the coordinate axis faces the direction of the time point which does not appear, the fixed time length is a fixed time length set by a worker, the time length is required to ensure that the arm of the user swings at least one piece of reciprocation, and a detection interval is established so as to collect data in the fixed time length, so that subsequent analysis is facilitated.
Step S301: and acquiring watch position information in the detection interval.
The position corresponding to the watch position information is the position of the watch at each time point in the interval, the position of the watch at the lowest longitudinal position is taken as the origin to establish a corresponding space coordinate system, and other watch positions are coordinate points on the space coordinate system.
Step S302: and determining a watch swinging path according to all the watch position information, and determining an arm rotating point and arm length information according to the watch swinging path.
The watch swinging path is an arc path which is formed by taking a single point as a rotating point and taking an arm as a rotating radius and is moved in a detection interval, the specific determination method is that the arm rotating point is a position point of a shoulder of a user, and a length value corresponding to arm length information is a distance value from the arm rotating point to the position of the watch.
Step S303: and determining a longitudinal compensation distance corresponding to the arm length information according to a preset compensation matching relation.
The longitudinal compensation distance is a distance value between the shoulder and the ear of the user and is in the longitudinal height of the space, the longitudinal compensation distances of the personnel with different heights are inconsistent, and in general, the distance between the shoulder and the ear of the user is larger as the distance between the shoulder and the ear of the user is larger, and the arm length of the personnel with the same height is longer as the distance between the shoulder and the ear is larger, so that the longitudinal compensation distance can be determined through the arm length, and the compensation matching relationship between the shoulder and the ear is determined through multiple tests by the personnel.
Step S304: and determining the ear position point at the arm rotation point according to the compensation distance and the preset transverse correction distance.
The lateral correction distance is a distance value of the position of the user's ear, which is different in the width direction of the user body from the position of the watch, and the value is determined by a worker in advance and is a constant value, at this time, the watch with the origin of the established spatial coordinate system is substantially in the same plane with the user's ear, and at this time, the ear position point is determined normally according to the spatial coordinate system established by the origin.
Referring to fig. 4, the method steps for determining the swing path of the wristwatch based on all the wristwatch position information include:
step S400: and acquiring an arc path formed by the position information of the adjacent watches in the detection interval.
The arc-shaped path is the path that the smart watch moves between two adjacent points in time.
Step S401: the rotation center point is determined according to the two watch position information and the arc-shaped path.
The rotation center point is a rotation point forming the arc path, and if the arc path cannot be used for determining the accurate rotation center point, no additional operation is performed.
Step S402: counting according to the times determined by each rotation center point to determine the center determination times.
The number of center determinations is the number of times each of the determined rotation center points is repeatedly determined, and can be determined by counting each rotation center point one by one.
Step S403: and determining the central determination times with the maximum numerical value according to a preset ordering rule, and defining the position corresponding to the watch position information for determining the rotation central point as an effective position.
The sorting rule is a method which is set by staff and can sort the values, such as an bubbling method, a rotation center point with the largest repetition number can be determined through the sorting rule, namely, more watch positions are located on the arc edge of the same circle, at the moment, the watch positions can be identified as watch positions determined by natural swinging in the walking process of a user, the corresponding watch positions are defined as effective positions for identification, so that differentiation of different watch positions is realized, and subsequent analysis is facilitated.
Step S404: the watch swinging path is determined according to each effective position.
The effective position information is used to determine a corresponding arcuate path through all effective positions, i.e., the watch swing path.
Referring to fig. 5, after the alert tone value is determined, the smart watch voice output method further includes:
step S500: and judging whether the prompting volume value is larger than a preset upper limit volume value.
The upper limit volume value is the maximum voice broadcast output volume which can be adjusted by the intelligent watch, and the purpose of judgment is to know whether the current voice output volume can be adjusted to meet the requirement.
Step S5001: if the prompting volume value is not larger than the upper limit volume value, outputting a voice prompting signal by using the prompting volume value.
When the prompting volume value is not larger than the upper limit volume value, the voice prompt signal can be normally output by adjusting the volume value to meet the requirement.
Step S5002: if the prompting volume value is larger than the upper limit volume value, outputting a vibration prompting signal and acquiring a signal transmitting position in real time.
When the prompting sound volume value is larger than the upper limit sound volume value, the playing sound is timely regulated to the maximum, so that the user still cannot hear the navigation information, and at the moment, a vibration prompting signal is output to enable the user to feel the sense of body, so that the user knows the situation and lifts the arm to enable the watch to approach to the position point of the ear; the signal transmitting position is the position where the watch is located.
Step S501: and determining the upper limit volume value and the demand distance information corresponding to the environment volume information according to a preset demand matching relation.
When the output volume value is the upper limit volume value, the distance value corresponding to the required distance information is required to enable the content of the voice broadcasting information to be transmitted to the distance value required when the user ear is the environment volume, different upper limit volume values and different environment volume values correspond to different required distance information, and the requirement matching relation among the three is determined in advance by a staff.
Step S502: and calculating according to the signal transmitting position and the ear position point to determine the distance information.
The distance value corresponding to the distance information is the distance value between the watch and the ear position point after sending out the vibration prompt signal.
Step S503: and outputting the voice prompt signal by using the upper limit volume value when the distance value corresponding to the distance information is smaller than the distance value corresponding to the required distance information.
When the distance value corresponding to the distance information is smaller than the distance value corresponding to the distance information, the fact that the voice broadcast is carried out by the upper limit volume value at the moment is indicated to enable the user to hear the navigation information, and the voice prompt signal output is normally carried out at the moment.
Referring to fig. 6, after outputting the voice prompt signal, the smart watch voice output method further includes:
step S600: and establishing a judging section with the width of a preset unit time length on a time axis, and controlling the rear end point of the judging section to coincide with the current time point.
The unit time length is a constant time length set by a worker, is generally 0.5s, and a judgment interval is established so as to be convenient for acquiring the condition of the voice prompt signal in unit time after being output, and is convenient for subsequent analysis.
Step S601: and acquiring an initial emission position of the front end point of the judgment section and a final emission position of the rear end point of the judgment section.
The initial transmitting position is the position of the watch when the front end point of the judging section is located, and the ending transmitting position is the position of the watch when the rear end point of the judging section is located.
Step S602: the initial standoff is determined by calculation from the initial firing position and the ear position point, and the termination standoff is determined by calculation from the termination firing position and the ear position point.
The initial distance is the distance value of the watch from the ear position point when the front end point of the judgment section is judged, the initial distance is obtained through the position corresponding to the initial transmitting position and the ear position point, the ending distance is the distance value of the watch from the ear position point when the rear end point of the judgment section is judged, and the initial distance is obtained through the position corresponding to the ending transmitting position and the ear position point.
Step S603: and carrying out difference calculation according to the ending separation distance and the initial separation distance to determine the unit movement distance.
The unit moving distance is a distance value of the watch moving towards the ear position point in the unit time length, and the distance value is obtained by subtracting the ending distance from the initial distance.
Step S604: and judging whether the unit moving distance is larger than a preset allowable distance.
The allowable distance is the minimum unit moving distance set by the staff and used for judging whether the user approaches the watch to the ear after outputting the voice prompt signal or not when the user possibly does not hear the navigation information to approach the ear.
Step S6041: if the unit moving distance is larger than the allowable distance, the voice prompt signal is output again.
When the unit moving distance is larger than the allowable distance, the situation that the user approaches the watch to the ear again is indicated, and the situation that the user does not hear the navigation information possibly exists, and at the moment, the voice broadcasting is performed again.
Step S6042: if the unit moving distance is not greater than the allowable distance, the original state is maintained.
When the unit moving distance is not greater than the allowable distance, the condition that the user approaches the watch to the ear again is not shown, and the original state is maintained.

step S700: and carrying out summation calculation according to the preset enhancement volume value and the environment volume information so as to update and determine new environment volume information.
When the unit moving distance is greater than the allowable distance, it is indicated that noise given to the user from outside may be larger than determined, and further analysis is required at this time; the enhancement volume value is a fixed value volume set by a worker, and the enhancement volume value is added with the original environment volume to update the environment volume so as to facilitate the subsequent matching of the corresponding output volume.
Step S701: and determining the target volume value corresponding to the environment volume information and the termination distance according to the preset updating matching relation.
The target volume value is an output volume value of the voice broadcast when the voice broadcast sound can be transmitted to the user's ear at the environment volume under the condition of stopping the distance, and the updated matching relation among the three values is determined in advance by a worker, and is not described in detail herein.
Step S702: and carrying out smaller value solving in the target volume value and the upper limit volume value to determine the smaller volume value, and controlling the intelligent watch to output the voice prompt signal at the smaller volume value.
And carrying out smaller value solving to determine whether the currently determined target volume value can be directly adjusted, so that the intelligent watch can output voice prompt signals according to the corresponding volume value, and a user can better hear navigation information.
