Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

The invention is operational with numerous general purpose or special purpose computing device environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet devices, multiprocessor devices, distributed computing environments that include any of the above devices or devices, and the like.

The embodiment of the invention provides a data transmission method, which can be applied to various system platforms, wherein an execution main body of the method can be first terminal equipment, and a flow chart of the method is shown in fig. 1, and specifically comprises the following steps:

S101: and acquiring first sensor data of each sensor preset in the first terminal equipment.

In the present invention, the first terminal device is provided with a plurality of sensors, which may specifically include: acceleration sensors, linear acceleration sensors, gravity sensors, gyroscopic sensors, rotation vector sensors, magnetic sensors, and the like.

It will be appreciated that the first terminal device acquires the first sensor data of each sensor in real time, e.g. each sensor data every 10 ms.

Optionally, the first terminal device in the embodiment of the present invention may detect whether a collision occurs in real time, and if the collision is detected, acquire each first sensor data.

S102: and judging whether the first terminal equipment collides with equipment or not based on the first sensor data.

In the invention, if the first terminal device collides, the first sensor data of each sensor in the first terminal device will change, for example, the linear acceleration will change 180 degrees in the direction of the three-dimensional space, and obvious collision peaks will appear in the gyroscope and the linear acceleration data. However, when the first terminal device collides, it cannot be determined whether the first terminal device collides with other terminal devices or other objects or human bodies. Therefore, whether the first terminal device collides with the device or not is judged through the first sensor data acquired currently.

S103: and when the first terminal equipment collides with the equipment, recording a first collision time point when the collision between the equipment occurs.

In the invention, when the first terminal device is determined to collide with other terminal devices, the collision time point when the first terminal device collides with other terminal devices is recorded.

S104: and starting an audio acquisition module preset in the first terminal equipment.

The audio collection module may be a microphone disposed in the first terminal device, and configured to collect vibration audio in a first preset time period.

It should be noted that, when the first terminal device starts the audio acquisition module, the terminal device that collides with the first terminal device also starts the audio acquisition module therein.

S105: and sending the first verification information to the terminal equipment within a preset range.

The first verification information comprises the first collision time point and a first equipment number of the first terminal equipment.

In the invention, after the first terminal collides, whether the data transmission connection needs to be constructed or not cannot be determined, and the terminal equipment which needs to carry out the data transmission cannot be determined, so that temporary connection is established with each terminal equipment in the preset range, and first verification information is sent to all the terminal equipment in the preset range.

S106: and when receiving the second verification information sent by any terminal equipment, determining the terminal equipment sending the second verification information as the second terminal equipment.

In the invention, in the preset range, if any terminal equipment collides with each other, the terminal equipment also sends verification information to all the terminal equipment in the preset range including the first terminal equipment.

S107: and determining a main vibration object based on the first verification information and the second verification information, and generating vibration by the main vibration object.

Wherein the main vibration object is the first terminal device or the second terminal device.

In the invention, after receiving the second verification information, the first terminal device cannot directly determine whether the second terminal device is a device colliding with the second terminal device. Therefore, after receiving the second verification information, the main vibration object that vibrates is determined based on the first verification information and the second verification information, and whether the main vibration object and the main vibration object are in close proximity to each other is verified by data acquired after the main vibration object vibrates.

S108: and acquiring second sensor data of each sensor in a first preset time period and first vibration audio acquired by the audio acquisition module.

In the present invention, the first preset period may be a vibration period during which the first terminal device generates the vibration signal after determining that the collision between the devices occurs. The primary vibrating object will also change each of its sensors when a vibration signal is generated.

If the first terminal device is the main vibration object, the second sensor data is the sensor data changed after the vibration is finished; if the first terminal device is not the main vibration object, the second sensor data may be consistent with the sensor data before vibration, or may be sensor data that is close to the first terminal device when the second terminal device vibrates, so that the sensor in the first terminal device senses that the second terminal device vibrates and then changes. The first vibration audio is audio data collected during a first preset time period.

S109: and sending first collision information corresponding to the first terminal equipment to the second terminal equipment.

The first collision information comprises the second sensor data and the first vibration audio acquired by the audio acquisition module.

In the invention, first collision information is formed by each second sensor data and the first vibration audio, and the collision information is sent to each terminal device in a preset range.

S110: and when receiving second collision information sent by the second terminal equipment, judging whether the first terminal equipment and the second terminal equipment are close to each other or not based on the first collision information and the second collision information.

In the present invention, after the main vibration object vibrates, the second terminal device also generates collision information and transmits the collision information to the first terminal device. The first terminal device and the second terminal device further verify whether the two parties are close to each other according to the received collision information of the other party and the collision information of the first terminal device and the second terminal device.

The second collision information comprises second vibration audio acquired by the second terminal equipment and third sensor data. The second vibration audio is audio data in a first preset time period acquired by an audio acquisition module in the second terminal equipment. If the second terminal equipment is a main vibration object, the third sensor data is sensor data which changes after the vibration is finished; if the second terminal device is not the main vibration object, the third sensor data may be consistent with the sensor data before vibration, or may be sensor data that is close to the second terminal device when the first terminal device vibrates, so that the sensor in the second terminal device senses that the first terminal device vibrates and then changes.

It will be appreciated that if the first terminal device and the second terminal device are in close proximity to each other, the collision time points of the two are identical or have a small difference, the vibration tones are similar, and the motion correlation calculated from the sensor data is high.

S111: if the first terminal equipment and the second terminal equipment are close to each other, establishing data transmission connection with the second terminal equipment, and realizing data transmission with the second terminal equipment.

In the invention, if the two terminal devices need to transmit data, the two terminal devices need to collide and then are close together, so that the first terminal device is identified to collide with the second terminal device, the first terminal device and the second terminal device are close to each other, the data transmission between the first terminal device and the second terminal device is represented, the data transmission connection between the first terminal device and the second terminal device is constructed, and the data can be transmitted between the first terminal device and the second terminal device after the connection is established.

In the data transmission method provided by the embodiment of the invention, the first sensor data of each sensor in the first terminal is acquired, and whether the first terminal equipment collides with other terminal equipment or not is judged, namely, whether the first terminal equipment collides with other terminal equipment or not is judged. If yes, recording a first collision time point, and starting an audio acquisition module. And sending the first verification information to the terminal equipment within the preset range, receiving the second verification information sent by other terminal equipment, and setting the terminal equipment sending the second verification information as the second terminal equipment. And determining a main vibration object generating vibration between the first terminal equipment and the second terminal equipment through the first verification information and the second verification information, and vibrating by the main vibration object. And acquiring second sensor data after each sensor changes in a first preset time period and first vibration audio acquired by the audio acquisition module. First collision information containing the second sensor data and the first vibration audio is generated and sent to the second terminal equipment. If the second collision information sent by the second terminal equipment is received, judging whether the first terminal equipment and the second terminal equipment are close to each other or not based on the first collision information and the second collision information, if so, data transmission is needed to be carried out between the first terminal equipment and the second terminal equipment, and data transmission connection is established to realize data transmission between the first terminal equipment and the second terminal equipment.

Based on the above embodiments, in the data transmission method provided by the present invention, the process of performing data transmission between terminal devices has a specific implementation process:

When terminal a and terminal B need to perform data transmission, a and B collide and abut together. A and B respectively acquire first sensor data of each sensor preset therein, and respectively judge whether collision between devices occurs. For the terminal A, when the collision between the devices is determined, a first collision time point is recorded, an audio acquisition module is started, and first verification information is sent to surrounding devices. And for the terminal B, when the collision between the devices is determined, recording a second collision time point, starting the audio acquisition module, and sending second verification information to surrounding devices. The terminal A and the terminal B determine a main vibration object between the terminal A and the terminal B according to the first verification information and the second verification information, and the main vibration object generates vibration. After the main vibration object vibrates, the terminal A acquires second sensor data of each sensor and first vibration audio acquired by the audio acquisition module in a first preset time period; and the terminal B acquires the third sensor data of each sensor and the second vibration audio acquired by the audio acquisition module in a first preset time period. The terminal A sends first collision information containing the second sensor data and the first vibration audio to the terminal B; the terminal B transmits second collision information including the respective third sensor data and the second vibration audio to the terminal a. After receiving the second collision information, the terminal A judges whether the terminal A and the terminal B are close to each other according to the first collision information and the second collision information; also, after receiving the first collision information, the terminal B determines whether the terminal a and the terminal B are close to each other according to the first collision information and the second collision information. If the two are determined to be mutually close to each other, establishing data transmission connection for data transmission.

By applying the method provided by the embodiment of the invention, the user can realize data transmission by only closely connecting two terminal devices, the operation is convenient, and the use experience of the user is improved.

Optionally, in the method provided by the embodiment of the present invention, a process of establishing, by a first terminal device, a data transmission connection with a second terminal device may specifically include:

Sending a first connection request to a second terminal device;

And when a first feedback message fed back by the second terminal equipment based on the first connection request is received and a second connection request sent by the second terminal equipment is received, feeding back a second feedback message corresponding to the second connection request to the second terminal equipment, and establishing data transmission connection with the second terminal equipment.

It can be understood that after the first terminal device and the second terminal device determine that the first terminal device and the second terminal device are close to each other, the connection requests are respectively sent to the opposite sides, after the connection requests sent by the opposite sides are received, feedback messages corresponding to the received connection requests are fed back, and data transmission connection is established.

In the method provided by the embodiment of the present invention, based on the content of S101, the acquiring the first sensor data of each sensor preset in the first terminal device may specifically include:

starting a detection application preset in the first terminal equipment;

In the data transmission method provided by the embodiment of the invention, the detection application is an application module which is arranged in the terminal equipment and used for realizing data transmission. Both terminal devices need to set detection applications to realize data transmission. The detection application is connected with all the sensors in the terminal equipment, and first sensor data of each sensor are collected according to a time period. Likewise, after the terminal device generates the vibration signal, the respective second sensor data generated due to the vibration signal are collected.

Optionally, in the foregoing embodiment of the present invention, the detection application may be started first to obtain the first sensor data of each sensor in the first terminal device. In the actual application process, there may be a situation that the detection application is not opened, so the collision detection device may be disposed in the terminal device to detect whether the terminal device collides in real time. When the terminal equipment collides, the first terminal equipment detects whether to start a detection application, if so, each first sensor data acquired by the detection application in the current time period is directly acquired; if not, prompting the user to start the detection application, and acquiring the first sensor data of each sensor in the first terminal equipment through the detection application after the user selects to start the detection application.

In particular, the detection application may extract statistical features of each sensor data in addition to collecting the sensor data. Referring to fig. 2, based on the content of S102, the determining, based on each of the first sensor data, whether the first terminal device collides with the device may include:

S201: and extracting first sensor statistical characteristics of each piece of first sensor data by using the detection application.

In the present invention, the sensor statistics include average, maximum, minimum, standard deviation, kurtosis and skewness of the sensor on the x, y, z axes.

S202: and acquiring a preset first support vector machine.

In the invention, a first support vector machine is a support vector machine SVM with a radial basis function RBF kernel, a large number of sensor statistical features are applied to the first support vector machine as training data for machine learning, a detection result corresponding to each sensor statistical feature is trained and identified, and when the error precision of the first support vector machine reaches a training condition, the first support vector machine is applied to identify each sensor statistical feature in the first terminal equipment.

S203: and inputting the statistical features of each first sensor into the first support vector machine to obtain a detection result output by the first support vector machine.

According to the invention, after machine learning training of a large amount of training data, the first support vector machine can identify the collision type of collision of the terminal equipment according to the input statistical characteristics of each sensor, and output a corresponding detection result.

S204: judging whether the detection result contains a first identification bit or not;

The first identification bit is identification information representing that the first terminal equipment collides with each other.

In the invention, if the first support vector machine recognizes that the collision of the first terminal equipment is the collision between the equipment, the first identification bit is marked on the output detection result, otherwise, the first identification bit is not marked. Therefore, the first terminal device determines whether the first terminal device collides with the device by judging whether the detection result contains the first identification bit. If yes, executing S205; if not, S206 is performed.

S205: and if the detection result comprises the first identification bit, determining that the first terminal equipment collides with equipment.

In the present invention, if the first terminal device collides with another device, it is further determined whether or not the terminal device is in close proximity to the first terminal device, and the above-described processes S103 to S108 are continuously performed.

S206: and if the detection result does not contain the first identification bit, determining that the first terminal equipment does not collide with the equipment.

In the invention, if the first terminal equipment does not collide with other terminal equipment, the data transmission is characterized in that the data transmission with other terminal equipment is not needed at present, and the detection application acquires the first sensor data of each sensor according to the time period.

In the data transmission method provided by the embodiment of the invention, after the first sensor data of each sensor in the first terminal equipment are acquired, the first sensor statistical characteristics of each first sensor data are extracted by the detection application, the statistical characteristics of each first sensor are input into the first support vector machine, and the collision type of the collision of the first terminal equipment is identified by the first support vector machine. Obtaining a detection result output by a first support vector machine, and judging whether the detection result contains a first identification bit or not; if so, the first terminal equipment collides with each other; otherwise, no collision between devices occurs. By identifying the type of collision that the first terminal device has made, false identification of collisions with people or other objects during normal application of the terminal device as inter-device collisions is avoided.

In the present invention, if two terminal devices need to transmit data, the two terminal devices must collide and abut against each other. In the actual application process, there may be a situation that the devices do not abut against each other after the collision between the devices, so the first terminal device needs to send the first collision information to all the terminal devices within the preset range, so that the terminal device that collides with the first terminal device further detects whether the two abut against each other. Similarly, the first terminal device will also receive the second collision information sent by the terminal device that needs to perform data transmission with the first terminal device within the preset range, and can identify whether the first terminal device and the second terminal device that sends the second collision information are close to each other according to the second collision information and the first collision information.

Therefore, referring to fig. 3, in the method provided by the embodiment of the present invention, based on the content of S110, the determining, based on the first collision information and the second collision information, whether the first terminal device and the second terminal device are close to each other may specifically include:

S301: and acquiring the third sensor data and the second vibration audio contained in the second collision information, and extracting the third sensor statistical characteristic of each third sensor data and the second sensor statistical characteristic of each second sensor data by using the detection application.
