Example one
A first data transmission method provided in an embodiment of the present application is applied to a data transmission device, and a scenario shown in fig. 1 is combined to describe in detail a data transmission method provided in an embodiment of the present application, it should be noted that fig. 1 is only an application scenario of the data transmission method provided in the first embodiment of the present application, and does not represent that the data transmission method must be applied to the scenario shown in fig. 1, and specifically may be applied to the data transmission device, referring to fig. 2, fig. 2 is a flowchart of the data transmission method provided in the first embodiment of the present application, and the method includes the following steps:
step 201, obtaining environmental data of the environment where the data transmission device is located.
The environmental data comprises a position and electromagnetic parameters of at least one object in an environment in which the data transmission device is located.
It should be noted that the position of the at least one object includes coordinates of the at least one object in the actual physical space, and for example, a coordinate system of the actual physical space may be established with a preset point as an origin, and then coordinates of the at least one object in the coordinate system may be determined. The preset point may be a center of the data transmission device, or may be another point, which is not limited in this application. The coordinates of the object may include coordinates of at least one sampling point of the object, optionally, the coordinates of the object may include coordinates of at least one sampling point of the surface of the object, or may include coordinates of at least one sampling point on the object contour line, and each object may determine the position of the object only by some sampling points, so that the acquisition speed of the environmental data is increased.
The electromagnetic parameter is used to indicate the ability of the object to transmit an electromagnetic wave, and may include, for example, the transmittance and/or reflectance of the object to the electromagnetic wave. Where the transmittance refers to the ability of an object to transmit an electromagnetic wave, the transmittance may be a ratio of the intensity of the electromagnetic wave after penetrating the object to the intensity of the electromagnetic wave before penetrating the object, and the intensity of the electromagnetic wave may include the power of the electromagnetic wave. The reflectivity refers to the ability of an object to reflect an electromagnetic wave, and may be a ratio of the intensity of the reflected electromagnetic wave to the intensity of the incident electromagnetic wave. This is merely an example and does not represent a limitation of the present application.
With reference to the foregoing description, optionally, in an implementation manner, acquiring environment data of an environment in which the data transmission device is located includes: acquiring an environment image of an environment where data transmission equipment is located; determining the coordinates of at least one object in the environment image in the actual physical space according to the environment image; and detecting the at least one object by using the electromagnetic waves based on the coordinates of the at least one object to obtain the transmittance and/or the reflectivity of the at least one object to the electromagnetic waves, wherein the electromagnetic parameters comprise the transmittance and/or the reflectivity. It should be noted that the image sensor may be used to acquire an environment image, and the image sensor may also be referred to as a photosensitive element, and is a device that converts an optical image signal into an electrical signal, and the image sensor may include a 2D image sensor, a binocular 3D image sensor, a depth image (RGBD) sensor, and the like, which are only exemplary. Further optionally, in determining the coordinates of the at least one object, the at least one object in the environment image may be identified using an image recognition algorithm, and the coordinates of the at least one object may be determined; alternatively, an image segmentation algorithm may be used to segment at least one object in the environment image and determine the coordinates of the at least one object, which is only an exemplary illustration, and the present application is not limited to the specific manner of determining the coordinates of the at least one object.
If the position and the electromagnetic parameters of the object are determined only by means of electromagnetic wave detection, the position of the object is difficult to determine quickly, a large amount of time and resources are consumed, and if the position and the electromagnetic parameters of the object are determined only by means of an image sensor, the electromagnetic parameters of the object cannot be acquired, so that the coordinates of at least one object and the electromagnetic parameters of at least one object can be determined quickly and accurately by combining an environment image and electromagnetic waves, the signal transmission quality can be determined conveniently, and a proper beam is selected for data transmission. It should be noted that in some application scenarios, the environment data may be stored through an environment model, that is, an environment model is established according to an environment image and electromagnetic parameters, and the environment data is stored.
Fig. 3 is a schematic diagram of establishing an environment model according to an embodiment of the present disclosure, as shown in fig. 3. Fig. 3 shows an image sensor, an antenna array, a transceiver module and a processing unit, wherein the image sensor is used for acquiring an environment image; the antenna array may employ an antenna phased array technology to transmit different beams, where one antenna in the antenna array is an array element, the antenna phased array technology changes a pattern shape of a beam by controlling a feed phase of a radiation unit in the antenna array, that is, changes a coverage of the beam, which is only described as an example here, and may also implement control of the coverage of the beam by using other technologies, and the antenna array may transmit N different beams, which may include beams of millimeter waves, and the like. The method comprises the steps of collecting an environment image by using an image sensor, then carrying out image segmentation on the environment image by using a processing unit, determining the position (coordinate) of each object, detecting the electromagnetic parameters of the objects by using beams emitted by an antenna array, fusing the environment image and the electromagnetic parameters by using the processing unit, establishing an environment model, and storing environment data.
Optionally, in another implementation, the environment data may further include a coverage of each of the at least one beam. Illustratively, obtaining environmental data of an environment in which the data transfer device is located includes: and mapping in the actual physical space according to the transmitting direction of at least one beam, and determining the coverage range of each beam in the at least one beam in the actual physical space. Alternatively, the coverage of the beams may be stored separately, i.e. the data transmission device acquires the environmental data as well as the coverage of the beams and then determines the signal transmission quality of each beam.
It should be noted that, the above two implementation manners may be implemented separately, or may be combined to form a new technical solution, and the present application is not limited thereto.
Step 202, according to the environment data, determining the signal transmission quality of at least one beam between the data transmission device and the opposite terminal device.
It should be noted that, data transmission may be performed between the data transmission device and the peer device through multiple beams, each beam may have multiple different transmission paths, and for each beam, the signal transmission quality of each transmission path of the beam may be determined. And a transmission path with good signal transmission quality is selected from all transmission paths, so that the data transmission quality can be better ensured.
Optionally, in a specific implementation manner, determining, according to the environment data, a signal transmission quality of at least one beam between the data transmission device and the peer device includes: determining a transmission path of at least one beam according to the coverage of the at least one beam, wherein the environment data comprises the coverage of the at least one beam; determining an object on the transmission path according to the coordinates of the at least one object and the transmission path; the signal transmission quality of the transmission path of the at least one beam is determined from the transmissivity and/or reflectivity of the object on the transmission path.
Based on the above implementation, two specific examples are listed here to further explain how to determine the transmission path and the object on the transmission path.
Optionally, in a first example, determining a transmission path of at least one beam according to a coverage of the at least one beam includes: determining whether the data transmission device is in motion based on the at least two environmental images; if the data transmission equipment moves, predicting by using the historical track of the data transmission equipment to obtain a predicted track of the data transmission equipment; and determining a transmission path of at least one beam according to the predicted track of the data transmission equipment and the coverage range of the at least one beam. It should be noted that the data transmission device may determine whether the data transmission device itself is moving or not, and also may determine whether the opposite device is moving or not, and as long as one device is moving, it needs to predict according to a historical trajectory of the moving device, and determine the transmission path according to the predicted trajectory. The transmission path is determined by utilizing the predicted track, and because the motion condition of the equipment is fully considered, the determined transmission path is more fit with the actual position of the equipment, and the better wave beam is favorably selected for data transmission.
Optionally, in a second example, determining the object on the transmission path according to the coordinates of the at least one object and the transmission path includes: determining whether a moving object exists in the environment where the data transmission equipment is located based on at least two environment images; if the moving object exists, predicting according to the historical track of the moving object to obtain the predicted track of the moving object; and if the moving object influencing the target transmission path is determined according to the predicted track of the moving object, taking the moving object as the object on the target transmission path. The two examples can be implemented separately or combined to form a new solution, and the present application is not limited thereto. The position of the object is determined by the predicted track, whether the object is shielded on the transmission path can be determined more accurately, and data transmission by the selected beam is facilitated.
Due to the occlusion of objects (such as pedestrians/vehicles) or the movement of data transmission devices (such as handheld terminals), the data transmission quality can be greatly affected. If the signal transmission quality of the current beam is detected, the actual physical space is searched when the signal transmission quality is reduced, the beam direction is updated, and the signal is interrupted or the quality is reduced in the process. According to the embodiment of the application, the moving object can be tracked by utilizing the environment image acquired by the image sensor, whether the moving object can affect the beam at a future moment is judged, and the target beam with high signal transmission quality is actively selected, so that signal interruption or quality reduction is avoided; and the predicted track can be obtained according to the historical track of the motion of the data transmission equipment, the position of the data transmission equipment at the next moment is predicted, and a target beam with high signal transmission quality is selected to be transmitted by combining the environmental data. Signal terminals are avoided, and high transmission quality is guaranteed.
It should be noted that, in another implementation manner, determining the signal transmission quality of at least one beam between the data transmission device and the peer device according to the environment data includes: determining the signal transmission quality of a current wave beam between the data transmission equipment and opposite terminal equipment according to the environment data; and if the signal transmission quality of the current beam is less than or equal to the preset signal transmission quality, determining the signal transmission quality of other beams except the current beam between the data transmission equipment and the opposite terminal equipment. In such implementations, the at least one beam for which signal transmission quality is to be determined may include the current beam, or the at least one beam for which signal transmission quality is to be determined may include the current beam and other beams. If the data transmission equipment and the opposite terminal equipment already use the beam for data transmission, the signal transmission quality of other beams can be determined when the signal transmission quality of the current beam is poor, and if the signal transmission quality of the current beam is good, the signal transmission quality of other beams does not need to be determined, and the current beam is continuously used as a target beam for data transmission, so that the calculation amount of the equipment can be reduced, and the efficiency is improved.
Step 203, determining a target beam in the at least one beam according to the signal transmission quality of the at least one beam.
It should be noted that, alternatively, a beam with the highest signal transmission quality may be selected as the target beam from among the at least one beam, and any one beam may be selected as the target beam from among the beams with the signal transmission quality greater than or equal to the preset threshold. It should be noted that, in the present application, the signal transmission quality may be expressed by signal strength or power, and the higher the signal strength is, the higher the signal transmission quality is. It should be noted that, in the case of supporting multiple beams, multiple target beams may be determined for data transmission.
And step 204, carrying out data transmission with the opposite terminal equipment by using the target beam.
If the data transmission equipment is a sending end, the data transmission equipment configures a target beam and carries data to be transmitted on the target beam for data transmission, and if the data transmission equipment is a receiving end, the data transmission equipment takes the target beam as a receiving beam and receives the data transmitted by opposite-end equipment.
With reference to the two examples listed in the step 202 and the description of the step 203-204, a specific application scenario is listed here to describe the data transmission method in detail. In this application scenario, taking millimeter waves as an example, an object with a transmittance greater than a preset transmittance is used as a shielding object, and an object with a reflectance greater than a preset reflectance is used as a reflecting object. If an occlusion object exists on the transmission path of the beam, the beam is not used as a target beam, that is, data cannot be transmitted, and if the beam is reflected by a reflection object and data can be transmitted to an opposite device, the beam can be used as a target beam. Referring to fig. 4, fig. 4 is a flowchart for determining a target beam according to an embodiment of the present application.
Environmental data of an environment in which the data transmission device is located is acquired. After obtaining the environmental data, it is necessary to determine the object on the transmission path. In the process, the data transmission device and the opposite terminal device are divided into a static scene and a dynamic scene according to whether the data transmission device and the opposite terminal device move or not. The data transmission device judges whether the data transmission device and the opposite terminal device move or not based on at least two environment images of the environment, wherein the at least two environment images can comprise image sequences arranged according to time sequence, for example, a reference object which is static relative to the ground is determined in the environment images, if the position of the data transmission device relative to the reference object in the environment images does not change, the data transmission device is determined not to move, and otherwise, the data transmission device moves. For another example, in some application scenarios, the peer device may be a device with a fixed location, and therefore, it is determined whether the location of the data transmission device relative to the peer device changes according to the environment image, and if the location changes, the data transmission device moves. And are intended to be exemplary only.
Specifically, the flow of the static scene includes: if the data transmission equipment and the opposite terminal equipment are determined not to move, entering a static scene; determining whether a moving object exists in the environment where the data transmission equipment is located based on at least two environment images; if not, determining the signal transmission quality of the transmission path of the at least one beam according to the transmissivity and/or reflectivity of the object on the transmission path; if the moving object exists, the predicted track of the moving object is obtained through prediction according to the historical track of the moving object, whether the moving object affects the target transmission path is determined according to the predicted track, if the moving object affects the target transmission path, the moving object belongs to the object on the target transmission path, and if the moving object does not affect the target transmission path, whether the moving object exists is continuously detected.
The flow of the dynamic scene comprises the following steps: if at least one of the data transmission equipment and the opposite terminal equipment is in a motion state, entering a dynamic scene; taking the motion of the data transmission equipment as an example, based on the environment image, the historical track of the data transmission equipment can be obtained, and the historical track of the data transmission equipment is used for predicting to obtain the predicted track of the data transmission equipment; determining a transmission path of at least one beam based on the predicted trajectory of the data transmission device, and determining an object on the transmission path.
The signal transmission quality of the transmission path of the at least one beam is determined from the transmissivity and/or reflectivity of the object on the transmission path. In this application scenario, the signal transmission quality of the beam with the blocking object on the transmission path is lower than the signal transmission quality of the beam without the blocking object on the transmission path, and therefore, the beam without the blocking object on the transmission path is preferentially selected as the target beam for data transmission. As shown in fig. 4, when the data transmission device and the peer device have performed data transmission by using the current beam, it may be determined whether an occlusion object exists on the transmission path of the current beam, that is, the signal transmission quality of the current beam is determined, and if an occlusion object exists on the transmission path of the current beam, another beam that is not occluded may be selected for data transmission. It should be noted that, if the signal transmission quality of the beam reflected by the reflecting object to reach the opposite device is high, that is, no shielding object exists on the transmission path of the beam reflected by the reflecting object to reach the opposite device, the beam may also be used as the target beam for data transmission.
The data transmission method described in conjunction with the above step 201-204 is further described by taking live video, remote medical treatment, and automatic driving as examples, and three specific examples are listed to further illustrate the specific application of the data transmission method provided in the embodiment of the present application.
Optionally, in a first example, as shown in fig. 5, fig. 5 is a schematic view of a live broadcast scene provided in an embodiment of the present application, where the data transmission device may be a terminal device that sends a live broadcast video, and the terminal device acquires environment data of an environment where the terminal device is located, where the environment data includes a position and an electromagnetic parameter of at least one object in the environment where the terminal device is located; acquiring a live video to be transmitted and address information of the live video, wherein the address information is used for indicating a destination address of opposite-end equipment for receiving the live video; determining the signal transmission quality of at least one wave beam between the terminal equipment and the opposite terminal equipment according to the environment data; determining a target beam among the at least one beam according to a signal transmission quality of the at least one beam; and transmitting the live broadcast video to the opposite terminal equipment by using the target wave beam. Similarly, if the terminal device receives the live video, the target beam can be determined, and the live video is received by using the target beam. It should be noted that, in an implementation manner, as shown in fig. 5, determining, according to environment data, a signal transmission quality of at least one beam between a data transmission device and a peer device includes: determining the signal transmission quality of a current wave beam between the data transmission equipment and opposite terminal equipment according to the environment data; and if the signal transmission quality of the current beam is less than or equal to the preset signal transmission quality, determining the signal transmission quality of other beams except the current beam between the data transmission equipment and the opposite terminal equipment. In a live broadcast scene, the transmission of the live broadcast video is continuously maintained between the data transmission equipment and the opposite terminal equipment, so that when the transmission quality of the current beam signal is poor, other beams with good signal transmission quality are selected to continue data transmission, beam switching is not required to be frequently performed, and the flow of live broadcast video transmission is ensured. Fig. 5 illustrates, by way of example, that the signal transmission quality of the beam 2 is higher than that of the current beam, and after the signal transmission quality is determined according to the environment data, data transmission is performed with the peer device using the beam 2, and fig. 5 is merely an example, which does not represent that the present application is limited thereto.
Optionally, in a second example, a telemedicine scenario is described, the data transmission device may be a terminal device, the terminal device obtains environment data based on image sensor acquisition and millimeter wave detection, determines signal transmission quality of at least one beam with the peer device based on the environment data, and uses the beam with the highest signal transmission quality as a target beam, and uploads field data to the peer device by using the target beam, where the field data may include medical image data, disease data input by a user and used for representing symptoms, and the like. The opposite terminal device uploads the field data to the server device and receives a diagnosis result (downlink data) sent by the server device.
