Under the above operating environment, the present application provides a method for controlling file transfer as shown in fig. 2. Fig. 2 is a flowchart of a file transfer control method according to a first embodiment of the present invention.
As shown in fig. 2, the file transfer control method of this embodiment may include the steps of:
step S12, the data sending device establishes a first connection with the data receiving device through the first communication means, sends a pairing request through the first connection and receives response information returned by the data receiving device;
step S14, the data sending device starts a second communication device to establish a second connection with the data receiving device according to the response information, and sends the file to be transmitted to the data receiving device through the second connection;
step S16, after the data sending device successfully sends the file to be transmitted, the second communication device is closed.
Through the steps S12 to S16, the second communication device is turned on only after the connection between the data sending device and the data receiving device is successfully established by effectively controlling the turning on and off of the second communication device during the file transmission process, and the second communication device is turned off immediately after the data sending device successfully sends the file to be transmitted, so that the purpose that only the first communication device consumes energy in the data sending device in a non-transmission scene is achieved, thereby achieving the technical effect of reducing the power consumption of the data sending device, and further solving the technical problem that the power consumption of the mobile device is large because the transmission device for transmitting the file in the mobile device consumes large power when the file is transmitted between the mobile devices at a short distance in the related art.
In the technical solution provided in step S12, the data sending device and the data receiving device may be a smart phone, a tablet computer, or other mobile devices. The type or model of the data sending device and the data receiving device may be the same or different. The data sending equipment and the data receiving equipment both comprise first communication devices, and the first communication devices are mainly used for establishing the connection relationship between the data sending equipment and the data receiving equipment. When the data sending device detects a data sending request, a first connection can be established with the data receiving device through the first communication device, the data sending device can send a pairing request to the data receiving device through the first connection, and the data receiving device responds to the pairing request sent by the data sending device after receiving the pairing request and feeds back response information to the data sending device. The first communication device may be a bluetooth chip, an NFC chip, or a WIFI chip, or the like. Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices, and building personal area networks. Near Field Communication (NFC) is integrated by non-contact radio frequency identification and interconnection technologies, and combines functions of an inductive card reader, an inductive card and a point-to-point on a single chip, so as to perform identification and data exchange with compatible devices in a short distance. The communication distance and the transmission rate of the Bluetooth and the NFC are different, the communication distance of the Bluetooth is about 10 meters, the transmission rate is 721kbps, the Bluetooth works on a frequency band of 2.4GHz, and one-to-many data transmission and voice communication are supported; the communication distance of NFC is about 20 cm, the transmission rate is 106kbps, 212kbps or 424kbps, and the NFC works on a frequency band of 13.56 MHz. The transmission rate and the communication distance of the WIFI chip are far higher than those of the Bluetooth chip and the NFC chip, but the power consumption of the WIFI chip is larger than those of the Bluetooth chip and the NFC chip. In order to reduce the power consumption of the data sending device, the data sending device preferably initiates the establishment of the first connection with the data receiving device using a low-speed, low-power consumption communication module, such as a bluetooth chip or an NFC chip.
Optionally, in this embodiment, the data sending device may establish the first connection with one or more data receiving devices at the same time, and when the data sending device establishes the first connection with multiple data receiving devices at the same time, the data sending device stores the identifiers of the multiple data receiving devices, so that the data sending device can distinguish different data receiving devices quickly and accurately.
The data sending device establishes a first connection with the data receiving device through the first communication device, the data sending device can send a pairing request to the data receiving device through the first connection, the data receiving device responds to the pairing request, and the specific response process can be matching of the pairing password. Optionally, if the connection relationship between the data sending device and the data receiving device is successfully established, the data sending device stores the connection relationship between the data sending device and the data receiving device, so that the connection relationship between the data sending device and the data receiving device does not need to be repeatedly established when subsequent file transmission is performed between the data sending device and the data receiving device, thereby effectively saving the file transmission time and improving the file transmission efficiency.
Taking the first communication device as a bluetooth chip as an example, a process of establishing a connection between the smart phone 1 and the smart phone 2 is described, where the smart phone 1 is used as a data sending device, and the smart phone 2 is used as a data receiving device, specifically: the smart phone 1 and the smart phone 2 both have bluetooth modules, and when the smart phone 1 detects a data transmission request, the bluetooth modules are turned on to search for nearby mobile devices and transmit pairing requests to the mobile devices. The smart phone 2 also starts the bluetooth module when detecting the pairing request sent by the smart phone 1. When the connection between the smart phone 1 and the smart phone 2 is established through the respective bluetooth modules, the smart phone 1 sends verification information to the smart phone 2, the verification information may be a pairing password, and when the pairing password of the smart phone 2 is matched with the pairing password of the smart phone 1, the establishment of the connection relationship between the smart phone 1 and the smart phone 2 is successful.
In the scheme provided in step S14, after the data sending device receives the response information returned by the data receiving device according to the pairing request, that is, after the data sending device and the data receiving device establish the first connection successfully, the first communication apparatus generates a trigger signal, where the trigger signal is a signal for triggering the data sending device to turn on the second communication apparatus. The data sending equipment can trigger the data sending equipment to start the second communication device according to the trigger signal. The data sending equipment can establish a second connection with the data receiving equipment by starting the second communication device, wherein the second connection can realize that the data sending equipment sends the file to be transmitted to the data receiving equipment.
The data sending equipment and the data receiving equipment are both provided with second communication devices, and the second communication devices are mainly used for establishing second connection between the data sending equipment and the data receiving equipment so as to facilitate file transmission. The second communication device in this embodiment may be a bluetooth chip, an NFC chip, or a WIFI chip, and since the transmission rate of the WIFI chip is much greater than that of the bluetooth chip or the NFC chip, the file transmission control method in this embodiment preferentially selects the second communication device as a high-speed and high-power-consumption communication module, for example, the WIFI chip, so as to achieve the technical effect of improving the file transmission efficiency.
In the file transfer control method of this embodiment, when the first communication device is used to establish the first connection between the data transmission apparatus and the data reception apparatus, the data transmission apparatus and the data reception apparatus only turn on the first communication device, and the second communication device is in a turned-off state. Only after the data sending device and the data receiving device establish the first connection successfully, the data sending device and the data receiving device start the second communication device to establish a second connection by using the second communication device, and files are transmitted between the data sending device and the data receiving device through the second connection. In the file transfer control method of the embodiment, only the first communication device is turned on and the second communication device is turned off in a non-file transfer scenario, and the second communication device is turned on in a file transfer scenario, so that the file transfer rate can be increased, and the power consumption of the data sending device and the data receiving device can be reduced.
The file to be transmitted sent by the data sending device can be a data file, a voice file or a video file, and the file to be transmitted is stored in a memory of the data sending device in the form of a data packet. Optionally, the data sending device sends the file to be transmitted to the data receiving device by copying the file to be transmitted in the memory, sending the copied file of the file to be transmitted to the data receiving device, and after the file to be transmitted is sent to the data receiving device, the file to be transmitted still exists in the data sending device, so that it can be ensured that the file to be transmitted can be sent to the data receiving device again once under the condition that the file to be transmitted fails to be sent.
Optionally, the data sending device may send the file to be transmitted to the data receiving device through the second connection, where one or more data receiving devices that establish the second connection relationship with the data sending device may be used. When the data sending device sends the file to be transmitted to the plurality of data receiving devices, the data sending device may adopt a serial transmission mode or a concurrent mode. The serial transmission mode is that the data sending equipment repeatedly sends files to be transmitted to the plurality of data receiving equipment one by one, and the concurrent transmission mode is that the data sending equipment simultaneously sends the files to be transmitted to the plurality of data receiving equipment. The file to be transmitted is transmitted to the data receiving equipment in a serial transmission mode, so that network resources are saved, but the transmission rate is low; the transmission rate of the file to be transmitted to the data receiving equipment is high by adopting a concurrent mode, but the occupied network resource is large.
In the file transfer control method of this embodiment, a first communication device is used to establish a first connection between a data sending device and a data receiving device, a second communication device is used to establish a second connection between the data sending device and the data receiving device, and a file is transferred between the data sending device and the data receiving device through the second connection.
In the scheme provided in step S16, the data sending apparatus will close the second communication device immediately after detecting that all the files to be transmitted have been sent to the data receiving apparatus. Optionally, the data sending device sends the file to be transmitted to the data receiving device by dividing the data packet of the file to be transmitted into a plurality of sub data packets, labeling each sub data packet in sequence, and storing the labels into a label set. The data sending equipment sends the plurality of sub data packets to the data receiving equipment in sequence according to the label sequence, in the sending process, the label of each sub data packet is deleted from the label set when the data sending equipment sends one sub data packet, and when the data sending equipment detects that the label set is an empty set, the file to be transmitted is completely sent to the data receiving equipment.
After the data sending device sends the file to be transmitted to the data receiving device, it cannot be said that the file received by the data receiving device is necessarily complete and effective, and the data receiving device is required to detect the received file. Optionally, the data receiving device may detect whether the file to be transmitted is successfully transmitted from the data transmitting device to the data receiving device by determining whether the labels of the sub data packets form a complete label set, and whether the sequence of the sub data packets is correct. And if the data receiving equipment detects that the received file is complete and effective, feeding back a confirmation message to the data sending equipment, wherein the confirmation message is used for notifying the data sending equipment that the file to be transmitted is successfully sent. If the data receiving device detects that the received file is not complete and effective, a failure message is fed back to the data sending device, the failure message is used for notifying the data sending device that the file to be transmitted fails to be sent, and at the moment, the data sending device resends the file to be transmitted to the data receiving device through the second connection.
After the data sending equipment receives the confirmation message fed back by the data receiving equipment, the data sending equipment immediately closes the second communication device, and the purpose of reducing the power consumption of the data sending equipment in a non-file transmission scene is achieved, so that the standby time of the data sending equipment is prolonged, and the technical effect of user experience is improved.
Through the above steps S12 to S16, when initiating the connection with the data receiving apparatus, the data sending apparatus only turns on the first communication device and turns off the second communication device, so that the power consumption of the data sending apparatus is only the first communication device, thereby reducing the power consumption of the data sending apparatus (since the power consumption of the first communication device is less than the power consumption of the second communication device). When the data sending device sends the file to be transmitted to the data receiving device, the data sending device starts the second communication device, so that the file transmission rate can be increased (because the transmission rate of the second communication device is greater than that of the first communication device). Through the embodiment, the technical problem that the power consumption of the mobile equipment is high due to the fact that a transmission device used for achieving file transmission in the mobile equipment consumes high power consumption when files are transmitted between the mobile equipment in a close range in the related technology is solved, and therefore the technical effects of reducing the power consumption of data sending equipment and improving the use experience of a user are achieved.
As an optional embodiment, after the step S12, that the data sending device establishes the first connection with the data receiving device successfully, the method for controlling file transfer of this embodiment may further include: the data transmission apparatus turns off the first communication device until the first communication device is turned back on after receiving the data transmission request next time.
The file transfer control method according to this embodiment may open the first communication device only when the data transmission apparatus detects a data transmission request, and immediately close the first communication device after establishing the first connection between the data transmission apparatus and the data reception apparatus using the first communication device. According to the file transmission control method, the second communication device is controlled to be started when the file to be transmitted is transmitted between the data sending device and the data receiving device, and then on the basis of reducing the power consumption of the device, the first communication device is controlled to be started only when the data sending device detects the data sending request, so that the power consumption of the data sending device can be further reduced, the standby time of the data sending device is prolonged, and the technical effect of using experience of a user is improved.
As an optional embodiment, the data sending device and the data receiving device may further include a third communication device, where the third communication device may serve as a replacement device for the first communication device and the second communication device when a failure occurs, and the third communication device in this embodiment may be used to establish a connection relationship between the data sending device and the data receiving device, or may be used to transfer a file between the data sending device and the data receiving device. Alternatively, the third communication device may be an NFC chip, a WIFI chip, or the like.

As an optional embodiment, fig. 3 is a flowchart of a control method for optional file transfer according to an embodiment of the present invention, and as shown in fig. 3, after the data sending device and the data receiving device successfully establish the first connection in step S12, the control method for file transfer according to this embodiment may further include the following steps:
in step S132, the data transmission apparatus identifies the distance to the data reception apparatus.
In the scheme provided in step S132, signal transmitting/receiving means may be provided in the data transmitting apparatus and the data receiving apparatus, and the distance between the data transmitting apparatus and the data receiving apparatus may be identified by the signal transmitting/receiving means, specifically: the signal transmitting device in the data transmitting equipment transmits a first signal to the data receiving equipment and records the time as a first time, when the signal receiving device in the data receiving equipment receives the first signal, a second signal is transmitted to the data transmitting equipment through the signal transmitting device in the data receiving equipment, the signal receiving device in the data transmitting equipment receives the second signal and records the time as a second time, and the distance between the data transmitting equipment and the data receiving equipment can be calculated by utilizing the time difference between the first time and the second time and the signal transmission rate. It should be noted that the distance between the data sending device and the data receiving device may be identified in other manners, and the present invention is not limited thereto.
Step S134, in a case that a distance between the data sending device and the data receiving device is within a preset distance, the data sending device receives a touch signal input by a user, where the touch signal is a signal generated when a touch interface of the data sending device receives a predetermined gesture operation, and the touch signal is used to trigger the data sending device to send a file to be transmitted to the data receiving device.
In the scheme provided in step S134, the preset distance may be adjusted according to actual requirements, for example, the preset distance may be 1 meter or 2 meters. After the distance between the data transmission device and the data reception device is recognized through step S132, it is determined whether the distance is within a preset distance. If the distance is within the preset distance, the data sending equipment can send the file to be transmitted to the data receiving equipment in a first mode; if the distance is not within the preset distance, the data sending device can send the file to be transmitted to the data receiving device in a second mode. Specifically, the method comprises the following steps:
the first way may be: the data sending equipment receives a touch signal input by a user, the touch signal is a signal generated when a touch interface of the data sending equipment receives a preset gesture operation, and the touch signal is used for triggering the data sending equipment to send a file to be transmitted to the data receiving equipment, namely when the data sending equipment receives the touch signal, the file to be transmitted is immediately sent to the data receiving equipment. The preset gesture operation can be set according to the operation habit of the user. Optionally, the predetermined operation gesture may include at least any one of the following operations: dragging the file to be transmitted according to a preset track, pressing the file to be transmitted for more than a preset time, clicking the file to be transmitted according to a preset number of times, zooming the file to be transmitted, and the like.
The second way may be: and executing preset operation according to the prompt message in the display interface of the data sending device, such as clicking a sharing button or a file sending button.
In an actual application scenario, when the two mobile devices are within a preset distance (for example, 2 meters), after the two mobile devices are successfully paired, a predetermined gesture operation (for example, two fingers are stroked up) may be directly performed in the sending device, that is, file transmission between the mobile devices may be implemented. When the two mobile devices exceed a preset distance (such as 2 meters), the files are transmitted in a traditional sharing mode.
According to the file transmission control method, the specific file transmission mode is set according to the distance between the data sending device and the data receiving device, when the distance between the devices is within the preset distance, the user gesture operation is additionally carried out to trigger the file to be transmitted, through the interactive design between the devices and the user, the file transmission dynamics is enhanced, and the user experience is improved.
As an alternative embodiment, fig. 4 is a flowchart of another alternative file transmission control method according to the first embodiment of the present invention, and as shown in fig. 4, step S12 may include the following steps:
step S122, the data sending device searches through the first communication device to obtain at least one terminal device within a preset range.
In the scheme provided in step S122, the preset range may be set according to actual situations, for example, the preset range may be a room, or may be within 5 meters of a square circle. The data sending equipment searches for the terminal equipment within the preset range through the first communication device, and the searched terminal equipment is the terminal equipment with the first communication device in the open state. The number of terminal devices searched by the data transmission device may be one or more. When the number of the terminal devices searched by the data transmission device is multiple, the data transmission device allocates identification IDs to the multiple terminal devices, so as to quickly and accurately distinguish different terminal devices.
Step S124, the data sending device initiates a pairing request to the searched terminal device through the first communication device, where the pairing request includes: corresponding to the pairing password of the terminal device.
In the scheme provided in step S124, the pairing request initiated by the data sending device to the searched terminal device through the first communication device may include a pairing password corresponding to the terminal device, and may also include authentication information corresponding to the terminal device, where the authentication information may be a specific keyword, or an answer to a certain question, and the like. The pairing password included in the pairing request may be set by the end user of the data transmission device. The embodiment can avoid the invasion of illegal files by setting the pairing password, and is favorable for ensuring the safety of data sending equipment.
Step S126, the data sending device determines one or more data receiving devices from at least one terminal device within a preset range according to the pairing request, wherein the data receiving device is the terminal device which responds to the pairing request and verifies the successful pairing password.
In the scheme provided in step S126, the determination of the data receiving device needs to meet the matching requirement of the pairing password in the pairing request, that is, the terminal device that can respond to the pairing request and successfully verify the pairing password among the plurality of terminal devices can be used as the data receiving device. The successful verification of the pairing password means that the password corresponding to the terminal device is matched with the pairing password set by the data transmission device. The file transfer control method of this embodiment may be implemented by one or more data receiving devices determined from a preset range.
Step S128, the data sending device establishes a communication link with the successfully paired data receiving device, where the data receiving device stores the trust information of the successfully paired data sending device.
In the scheme provided in step S128, after determining the data receiving device matching with the data sending device, the data sending device establishes a communication link with the data receiving device, where the communication link is used to transmit a file to be sent in the data sending device and an interactive message between the data sending device and the data receiving device. After the communication link between the data sending device and the data receiving device is successfully established for the first time, the trust information of the data sending device successfully paired with the data receiving device can be stored in the data receiving device, so that the data sending device directly passes verification according to the trust information when initiating the pairing request again. Optionally, the data sending device may also store information of the data receiving device successfully paired with the data sending device, and when the connection relationship between the data sending device and the data receiving device is established again, repeated verification is not required, so that the purpose of improving the file transmission efficiency is achieved.
Through the above steps S122 to S128, when the connection between the data sending device and the data receiving device is established, the embodiment improves the reliability and the security of establishing the connection relationship between the data sending device and the data receiving device by setting the pairing password, so as to avoid the intrusion of illegal files in the data sending device and the data receiving device, and be beneficial to ensuring the security of file transmission.
The file transfer control method of the embodiment can be applied to a scene of performing close-range file transfer between mobile devices under an android or IOS operating system. By using the file transfer control method of the embodiment, an application program can be designed, and the application program can be installed in a mobile device with an android or IOS operating system. In a practical application scenario, the first communication device is preferably a bluetooth 4.0, and the second communication device is preferably a WiFi module. The mobile device adopts Bluetooth 4.0 when pairing, and does not turn on the WiFi module, and the Bluetooth 4.0 low power consumption mode leads to 1/100 that the standby power consumption is reduced by normal Bluetooth. The WiFi module is opened only when a user initiates file transmission, file transmission is carried out by using the WiFi Direct, the transmission rate can reach 802.11kbps on a working frequency band of 5GHz according to a communication protocol theory, and the file transmission rate is greatly increased. After the file is successfully transmitted, the WiFi module is immediately closed, so that the standby power consumption is reduced, and the standby time is prolonged.
It should be noted that, for simplicity of description, the above-mentioned method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the order of acts, as some steps may occur in other orders or concurrently in accordance with the invention. Further, those skilled in the art should also appreciate that the embodiments described in the specification are preferred embodiments and that the acts and modules referred to are not necessarily required by the invention.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
Example 2
According to the embodiment of the present invention, another method embodiment of a file transfer control method is also provided, and it should be noted that the method embodiment provided in the second embodiment of the present application may also be executed in a mobile terminal, a computer terminal, or a similar computing device. In the operating environment shown in fig. 1 of the present application, a second embodiment of the present application provides a method for controlling file transfer as shown in fig. 5, where fig. 5 is a flowchart of the method for controlling file transfer according to the second embodiment of the present invention.
As shown in fig. 5, the file transfer control method of this embodiment may include the steps of:
step S22, the data receiving device establishes a first connection with the data sending device through the first communication device, receives the pairing request sent by the data sending device through the first connection and returns the response information to the pairing request;
step S24, the data receiving device starts the second communication device to establish the second connection with the data sending device, and receives the file transmitted by the data sending device through the second connection;
in step S26, after the data receiving apparatus successfully receives the file, the second communication device is closed.
Through the above steps S22 to S26, the data receiving apparatus only turns on the first communication means and turns off the second communication means when establishing the first connection with the data transmitting apparatus, so that the power consumption of the data receiving apparatus is only the first communication means, thereby reducing the power consumption of the data receiving apparatus. When the data receiving equipment receives the file transmitted by the data transmitting equipment, the data receiving equipment starts the second communication device, so that the file transmission rate can be improved. Through the embodiment, the technical problem that the power consumption of the mobile equipment is high due to the fact that a transmission device used for achieving file transmission in the mobile equipment consumes high power consumption when files are transmitted between the mobile equipment in a close range in the related technology is solved, and therefore the technical effects of reducing the power consumption of data receiving equipment and improving the use experience of a user are achieved.
In the technical solution provided in step S22, the data sending device and the data receiving device may be a smart phone, a tablet computer, or other mobile devices. The type or model of the data sending device and the data receiving device may be the same or different. The data sending equipment and the data receiving equipment respectively comprise a first communication device, the first communication device is mainly used for establishing first connection between the data sending equipment and the data receiving equipment, the data receiving equipment can receive a pairing request sent by the data sending equipment through the first connection, and response information of the pairing request is fed back to the data sending equipment. When the data sending equipment detects a data sending request, a first connection with the data receiving equipment can be established through the first communication device of the data sending equipment, and after the data receiving equipment receives a pairing request sent by the data sending equipment, the first communication device of the data receiving equipment can be started, and the first connection with the data sending equipment is established by utilizing the first communication device of the data receiving equipment.
Alternatively, the first communication device may be a bluetooth chip, an NFC chip, or a WIFI chip, or the like. Bluetooth is a wireless technology standard that enables short-range data exchange between fixed devices, mobile devices, and building personal area networks. Near Field Communication (NFC) is integrated by non-contact radio frequency identification and interconnection technologies, and combines functions of an inductive card reader, an inductive card and a point-to-point on a single chip, so as to perform identification and data exchange with compatible devices in a short distance. The communication distance and the transmission rate of the Bluetooth and the NFC are different, the communication distance of the Bluetooth is about 10 meters, the transmission rate is 721kbps, the Bluetooth works on a frequency band of 2.4GHz, and one-to-many data transmission and voice communication are supported; the communication distance of NFC is about 20 cm, the transmission rate is 106kbps, 212kbps or 424kbps, and the NFC works on a frequency band of 13.56 MHz. The transmission rate and the communication distance of the WIFI chip are far higher than those of the Bluetooth chip and the NFC chip, but the power consumption of the WIFI chip is larger than those of the Bluetooth chip and the NFC chip. In order to reduce power consumption of the data receiving device, the data receiving device preferably establishes a connection with the data transmitting device using a low-speed low-power communication module, such as a bluetooth chip or an NFC chip.
Optionally, after the data receiving device receives the pairing request initiated by the data sending device, the process that the data receiving device responds to the pairing request may include: and matching verification information, wherein the verification information can be a pairing password, a keyword or an answer of a specific question and the like. By matching the authentication information between the data transmission device and the data reception device, the reliability and security of establishing a connection relationship between the data transmission device and the data reception device can be increased.
Optionally, if the data receiving device successfully establishes the first connection with the data sending device through the first communication device, the data receiving device stores the connection relationship with the data sending device and the verification information required when establishing the connection relationship, so that when the data sending device initiates the connection establishment with the data receiving device again, the matching process of the verification information and the establishment process of the connection do not need to be repeated, thereby effectively saving the transmission time of the file and improving the transmission efficiency of the file.
Taking the first communication device as a bluetooth chip as an example, a process of establishing a connection between the smart phone 1 and the smart phone 2 is described, where the smart phone 1 is used as a data sending device, and the smart phone 2 is used as a data receiving device, specifically: the smart phone 1 and the smart phone 2 both have bluetooth modules, and when the smart phone 1 detects a data transmission request, the bluetooth modules are turned on to search for nearby mobile devices and transmit pairing requests to the mobile devices. The smart phone 2 also starts the bluetooth module when detecting the pairing request sent by the smart phone 1. When the connection between the smart phone 1 and the smart phone 2 is established through the respective bluetooth modules, the smart phone 1 sends verification information to the smart phone 2, the verification information may be a pairing password, and when the pairing password of the smart phone 2 is matched with the pairing password of the smart phone 1, the establishment of the connection relationship between the smart phone 1 and the smart phone 2 is successful.
In the scheme provided in step S24, when the first connection between the data receiving device and the data sending device is successfully established, the data receiving device returns response information to the data sending device to notify the data sending device that the connection relationship is successfully established. Meanwhile, a first communication device in the data receiving device generates a trigger signal, wherein the trigger signal is a signal for triggering the data receiving device to turn on a second communication device. And the data receiving equipment starts a second trigger device to establish a second connection with the data sending equipment, and the file to be transmitted sent by the data sending equipment is received through the second connection.
The data sending equipment and the data receiving equipment are both provided with second communication devices, the second communication devices are mainly used for establishing second connection between the data sending equipment and the data receiving equipment, and files can be transmitted between the data sending equipment and the data receiving equipment through the second connection. The second communication device in this embodiment may be a bluetooth chip, an NFC chip, or a WIFI chip, and since the transmission rate of the WIFI chip is much greater than that of the bluetooth chip or the NFC chip, the file transmission control method in this embodiment selects the second communication device as a high-speed high-power consumption communication module, such as a WIFI chip, so as to achieve the technical effect of improving the file transmission efficiency.
In the file transfer control method of this embodiment, when the data receiving apparatus establishes the first connection with the data transmitting apparatus by using the first communication device, the data receiving apparatus and the data transmitting apparatus only turn on the first communication device, and the second communication device is in a turned-off state. Only after the data receiving device and the data sending device successfully establish the first connection, the data sending device and the data receiving device start the second communication device so as to establish a second connection between the data sending device and the data receiving device by using the second communication device, and files are transmitted between the data sending device and the data receiving device through the second connection. In the file transfer control method of the embodiment, only the first communication device is turned on and the second communication device is turned off in a non-file transfer scenario, and the second communication device is turned on in a file transfer scenario, so that the file transfer rate can be increased, and the power consumption of the data sending device and the data receiving device can be reduced.
The file transmitted by the data transmitting apparatus received by the data receiving apparatus may be a data file, a voice file, a video file, or the like. Optionally, the file to be transmitted may be stored in a memory of the data sending device in the form of a data package, and the data sending device may copy the file to be transmitted in the memory to send the copied file of the file to be transmitted to the data receiving device. After the file to be transmitted is sent to the data receiving equipment, the file to be transmitted also exists in the data sending equipment, so that the file to be transmitted can be sent to the data receiving equipment again once under the condition that the file to be transmitted is failed to be sent by the data sending equipment.
Alternatively, the data sending device may transmit the file to the data receiving device by dividing the data packet of the file to be transmitted into a plurality of sub data packets, and assigning a sequential label to each sub data packet, and the data sending device sends the plurality of sub data packets to the data receiving device one by one according to the label sequence. When the data receiving equipment receives the sub data packets, the data receiving equipment sequences the sub data packets according to the labels of the sub data packets so as to achieve the purpose of restoring the source file. The embodiment adopts the form of dividing the file data packet into the sub-data packets, so that the consumption of network bandwidth in the file transmission process can be reduced, and the effect of improving the file transmission rate is further achieved.
In the file transfer control method of this embodiment, a first communication device is used to establish a first connection between a data sending device and a data receiving device, a second communication device is used to establish a second connection between the data sending device and the data receiving device, and a file is transferred between the data sending device and the data receiving device through the second connection.
In the scheme provided in step S26, the second communication means is turned off immediately after the data receiving apparatus detects that the file is successfully received. Optionally, the data receiving device may detect whether the file is successfully received by the following method: judging whether the labels of the received sub data packets form a complete label set, wherein the label set is a set of labels of a plurality of sub data packets which are sent to a data receiving device by a data sending device and are divided into files to be transmitted before the files are transmitted; or judging whether the sequence of the sub-packets is correct, wherein the data sending device sends the label set to the data receiving device and simultaneously informs the data receiving device of the sequence of the labels of the plurality of sub-packets. When the data receiving equipment detects that the label sequence of the received multiple sub-data packets is correct and the multiple labels can form a complete label set, the data receiving equipment successfully receives the file; otherwise the data receiving device fails to successfully receive the file.
Optionally, in a case that the data receiving device detects that the file is successfully received, the data receiving device may feed back an acknowledgement message to the data sending device, where the acknowledgement message is used to notify the data sending device that the file is successfully transmitted. And under the condition that the data receiving equipment detects that the file cannot be successfully received, feeding back a failure message to the data sending equipment, wherein the failure message is used for notifying the data sending equipment that the file transmission fails, at the moment, the data sending equipment retransmits the file to the data receiving equipment by using the second connection, and the data sending equipment and the data receiving equipment do not close the second communication device until the data sending equipment receives a confirmation message fed back by the data receiving equipment.
After the data receiving device successfully receives the file, that is, after the data receiving device feeds back the confirmation message to the data sending device, the data receiving device will immediately close the second communication device of itself, and the data sending device will also immediately close the second communication device of itself after receiving the confirmation message, so as to achieve the purpose of reducing the power consumption of the data receiving device and the data sending device in a non-file transmission scene, thereby realizing the purpose of prolonging the standby time of the data receiving device and the data sending device, and improving the technical effect of user experience.
Through the above steps S22 to S26, the data receiving apparatus only turns on the first communication device and turns off the second communication device when receiving the pairing request initiated by the data sending apparatus, so that the power consumption of the data receiving apparatus is only the first communication device, thereby reducing the power consumption of the data receiving apparatus (since the power consumption of the first communication device is less than the power consumption of the second communication device). When the data receiving equipment receives the file transmitted by the data sending equipment, the data receiving equipment starts the second communication device, so that the file transmission rate can be increased (because the transmission rate of the second communication device is greater than that of the first communication device). Through the embodiment, the technical problem that the power consumption of the mobile equipment is high due to the fact that a transmission device used for achieving file transmission in the mobile equipment consumes high power consumption when files are transmitted between the mobile equipment in a close range in the related technology is solved, and therefore the technical effects of reducing the power consumption of data receiving equipment and improving the use experience of a user are achieved.
As an optional embodiment, after the step S22, that the data receiving apparatus establishes the first connection successfully with the data sending apparatus through the first communication device, the method for controlling file transfer of this embodiment may further include: the data receiving equipment closes the first communication device until the first communication device is restarted after a pairing request of the data sending equipment is received next time.
The data receiving device of this embodiment may turn on the first communication apparatus only when receiving the pairing request initiated by the data sending device, and turn off the first communication apparatus immediately after the first communication apparatus successfully establishes the first connection with the data sending device. According to the file transmission control method, the second communication device is controlled to be started when the data receiving equipment receives the file transmitted by the data sending equipment, so that the power consumption of the data receiving equipment is reduced, and the first communication device is controlled to be started only when the pairing request initiated by the data sending equipment is received, so that the power consumption of the data receiving equipment can be further reduced, the standby time of the data receiving equipment is prolonged, and the technical effect of user experience is improved.
As an optional embodiment, fig. 6 is a flowchart of a control method of optional file transfer according to a second embodiment of the present invention, and as shown in fig. 6, after the data receiving device receives the file transferred by the data sending device through the second connection in step S24, the control method of file transfer according to this embodiment may further include the following steps:
step S252, the data receiving device detects whether the received file is complete;
in step S254, when the file is detected to be complete, the data receiving device feeds back a confirmation message to the data sending device, where the confirmation message is a message used to indicate that the file received by the data receiving device is a complete file.
In the scheme provided in step S252, the data receiving device may determine whether the labels of the received sub data packets can form a complete label set, where the label set is a set of labels of a plurality of sub data packets that are divided into the data packets of the file to be transmitted and sent to the data receiving device by the data sending device before the file is transmitted; or judging whether the sequence of the sub-data packets is correct, wherein the data sending device sends the label set to the data receiving device and simultaneously informs the data receiving device of the sequence of the labels of the plurality of sub-data packets so as to detect whether the received file is complete. When the data receiving device detects that the label sequence of the received multiple sub-data packets is correct and the multiple labels can form a complete label set, it indicates that the file received by the data receiving device is complete.
In the scheme provided in step S254, in a case that it is detected that the file is complete, the data receiving device feeds back a confirmation message to the data sending device, where the confirmation message is a message used for indicating that the file received by the data receiving device is a complete file; and under the condition that the file is detected to be incomplete, the data receiving equipment feeds back failure to the data sending equipment, wherein the failure message is used for indicating that the file received by the data receiving equipment is an incomplete file. The data sending equipment closes the second communication device after receiving the confirmation message, retransmits the file through the second connection after receiving the failure message, and closes the second communication device until receiving the confirmation message.
The data receiving device in this embodiment notifies the data sending device whether the file is successfully transmitted or not by detecting whether the received file is complete and feeding back an acknowledgement message or a failure message to the data sending device, which is beneficial to accurately controlling the closing time of the second communication device in the data sending device and the data receiving device, thereby achieving the purpose of reducing the power consumption of the data sending device and the data receiving device.
The file transfer control method of the embodiment can also be applied to a scene of performing close-range file transfer between mobile devices under an android or IOS operating system. An application program can be designed by using the file transfer control method of the embodiment, and the application program can be installed in a mobile device with an android or IOS operating system.

The mobile device adopts Bluetooth 4.0 when pairing, and does not turn on the WiFi module, and the Bluetooth 4.0 low power consumption mode leads to 1/100 that the standby power consumption is reduced by normal Bluetooth. The WiFi module is opened only when a user initiates file transmission, file transmission is carried out by using the WiFi Direct, the transmission rate can reach 802.11kbps on a working frequency band of 5GHz according to a communication protocol theory, and the file transmission rate is greatly increased. After the file is successfully transmitted, the WiFi module is immediately closed, so that the standby power consumption is reduced, and the standby time is prolonged.

According to an embodiment of the present invention, there is also provided a file transfer control system for implementing the file transfer control method described above in the present application, and fig. 15 is a schematic diagram of the file transfer control system according to the embodiment of the present invention, and as shown in fig. 15, the system includes:
the data transmission apparatus 1520 includes: a first transmitting means 15201 and a second transmitting means 15203 for initiating a connection request through the first transmitting means 15201; and a data receiving apparatus 1540 including: the first receiving apparatus 15401 and the second receiving apparatus 15403 are configured to receive the connection request through the first receiving apparatus 15401, where after the first connection between the data sending device 1520 and the data receiving device 1540 is successfully established, the data sending device 1520 starts the second sending apparatus 15203, the data receiving device 1540 starts the second receiving apparatus 15403, a second connection is established between the data sending device 1520 and the data receiving device 1540, and after the data sending device 1520 successfully sends the file to be transmitted to the data receiving device 1540 through the second connection, the second sending apparatus 15203 is closed, and after the data receiving device 1540 successfully receives the file through the second connection, the second receiving apparatus 15403 is closed.
Alternatively, the data sending device 1520 and the data receiving device 1540 may be smart phones, tablets, or other mobile devices. The data transmitting apparatus 1520 and the data receiving apparatus 1540 may be the same type or model, or may be different. The first transmitting device 15201 and the first receiving device 15401 are substantially the first communication device in the embodiment of the present application, and may be low-speed and low-power communication modules, and are mainly used to establish the first connection between the data transmitting apparatus 1520 and the data receiving apparatus 1540. The data transmitting apparatus 1520 transmits a pairing request to the data receiving apparatus 1540 through the first connection, and the data receiving apparatus 1540 feeds back response information of the pairing request to the data transmitting apparatus 1520. The first transmitting device 15201 and the first receiving device 15401 may be a bluetooth chip, an NFC chip, a WIFI chip, or the like. The transmission rate and the communication distance of the WIFI chip are far higher than those of the Bluetooth chip and the NFC chip, but the power consumption of the WIFI chip is larger than those of the Bluetooth chip and the NFC chip. In order to reduce power consumption of the data transmitting apparatus 1520 and the data receiving apparatus 1540, the first transmitting device 15201 and the first receiving device 15401 each preferably employ a bluetooth chip or an NFC chip.
Optionally, after the data sending apparatus 1520 sends the connection request to the data receiving apparatus 1540 by using the first sending device 15201, the data receiving apparatus 1540 responds to the connection request by using the first receiving device 15401, and the specific response process may include: and matching verification information, wherein the verification information can be a pairing password, a keyword or an answer of a specific question and the like. By matching the authentication information between the data transmitting apparatus 1520 and the data receiving apparatus 1540, the reliability and security of establishing a connection relationship between the data transmitting apparatus 1520 and the data receiving apparatus 1540 can be increased.
Optionally, if the data sending device 1520 and the data receiving device 1540 successfully establish a connection, the data receiving device 1540 stores the connection relationship and the verification information required for establishing the connection relationship, so that when the data sending device 1520 initiates the connection establishment with the data receiving device 1540 again, the matching process of the verification information and the establishment process of the connection do not need to be repeated, thereby effectively saving the transmission time of the file and improving the transmission efficiency of the file.
After the data transmitting apparatus 1520 and the data receiving apparatus 1540 are successfully connected, the data transmitting apparatus 1520 opens the second transmitting device 15203, the data receiving apparatus 1540 opens the second receiving device 15403, and a second connection is established between the data transmitting apparatus 1520 and the data receiving apparatus 1540, by which a file can be transferred between the data transmitting apparatus 1520 and the data receiving apparatus 1540. The second transmitting device 15203 and the second receiving device 15403 are substantially the second communication device in the embodiment of the present application, and may be high-speed and high-power communication modules. Optionally, the second transmitting device 15203 and the second receiving device 15403 may be a bluetooth chip, an NFC chip, a WIFI chip, or the like, and since the transmission rate of the WIFI chip is much greater than that of the bluetooth chip or the NFC chip, the file transmission control system of this embodiment preferentially selects the second transmitting device 15203 and the second receiving device 15403 as the WIFI chip, so as to achieve the technical effect of improving the file transmission efficiency.
Alternatively, the file to be transmitted by the second transmitting device 15203 may be a data file, a voice file, a video file, or the like, and the file to be transmitted is stored in the memory of the data transmitting apparatus 1520 in the form of a data package. Optionally, the data sending device 1520 sends the file to be transmitted to the data receiving device 1540 by copying the file to be transmitted in the memory, and sending the copied file of the file to be transmitted to the data receiving device 1540, and after the file to be transmitted is sent to the data receiving device 1540, the file to be transmitted still exists in the data sending device 1520, so that it can be ensured that the file to be transmitted can be sent to the data receiving device 1540 again when the file to be transmitted fails to be sent.
The control system of file transfer of this embodiment establishes a first connection between the data transmitting apparatus 1520 and the data receiving apparatus 1540 using the first transmitting device 15201 and the first receiving device 15401, after the first connection is successfully established, the second transmitting device 15203 and the second receiving device 15403 are opened, a second connection between the data transmitting apparatus 1520 and the data receiving apparatus 1540 is established, and files are transmitted between the data transmitting apparatus 1520 and the data receiving apparatus 1540 by means of the connection, preferably, the power consumption of the first transmitting device 15201 and the first receiving device 15401 is lower than the power consumption of the second transmitting device 15203 and the second receiving device 15403, the transmission rate of the second transmitting device 15203 and the second receiving device 15403 is higher than the transmission rate of the first transmitting device 15201 and the first receiving device 15401, the embodiment can improve the file transmission rate, reduce the power consumption of the equipment and greatly improve the use experience of users.
After the data transmitting apparatus 1520 successfully transmits the file to be transmitted to the data receiving apparatus 1540 through the second connection, the second transmitting device 15203 is closed, and after the data receiving apparatus 1540 successfully receives the file, the second receiving device 15403 is closed.
Alternatively, the data transmitting apparatus 1520 may transmit the file to be transmitted to the data receiving apparatus 1540 by dividing the data packet of the file to be transmitted into a plurality of sub data packets, labeling each sub data packet in sequence, and storing the labels into a label set. The data transmitting apparatus 1520 uses the second transmitting device 15203 to sequentially transmit the plurality of sub-packets to the data receiving apparatus 1540 according to the label sequence, during the transmission, each time the data transmitting apparatus 1520 transmits one sub-packet, the label of the sub-packet is deleted from the label set, and when the data transmitting apparatus 1520 detects that the label set is an empty set, it indicates that all the files to be transmitted have been transmitted to the data receiving apparatus 1540.
Alternatively, the data receiving apparatus 1540 may detect whether the file is successfully received in the following manner: judging whether the labels of the received sub data packets form a complete label set, wherein the label set is a set of labels of a plurality of sub data packets divided by the data packets of the file to be transmitted, which are sent to the data receiving device 1540 by the data sending device 1520 before the file is transmitted; or whether the order of the sub-packets is correct is determined, wherein the data transmitting apparatus 1520 notifies the data receiving apparatus 1540 of the order of the labels of the plurality of sub-packets while transmitting the label set to the data receiving apparatus 1540. When the data receiving device 1540 detects that the label sequence of the received multiple sub-data packets is correct, and the multiple labels can form a complete label set, it indicates that the data receiving device 1540 successfully receives the file; otherwise the data receiving apparatus 1540 fails to successfully receive the file.
Alternatively, in case that the data receiving apparatus 1540 detects that the file is successfully received, the data receiving apparatus 1540 may feed back an acknowledgement message to the data transmitting apparatus 1520, where the acknowledgement message is used to notify the data transmitting apparatus 1520 that the file transmission is successful. When the data receiving apparatus 1540 detects that the file cannot be successfully received, a failure message for notifying that the file transmission of the data transmitting apparatus 1520 fails is fed back to the data receiving apparatus 1520, at this time, the data transmitting apparatus 1520 retransmits the file to the data receiving apparatus 1540 by using the second connection, until the data transmitting apparatus 1520 receives a confirmation message fed back by the data receiving apparatus 1540, the data transmitting apparatus 1520 does not close the second transmitting device 15203, and the data receiving apparatus 1540 does not close the second receiving device 15403.
With the file transfer control system according to this embodiment, only the first transmission device 15201 and the first reception device 1540 are opened when the connection between the data transmission apparatus 1520 and the data reception apparatus 1540 is established, the second transmission device 15203 and the second reception device 15403 are opened after the connection is successfully established, and the second transmission device 15203 and the second reception device 15403 are closed after the file is transferred between the data transmission apparatus 1520 and the data reception apparatus 1540 by the second transmission device 15203 and the second reception device 15403. The embodiment solves the technical problem that the power consumption of the mobile equipment is large due to the fact that a transmission device used for achieving file transmission in the mobile equipment consumes large power consumption when files are transmitted between the mobile equipment in a close range in the related art, and achieves the technical effects of improving file transmission efficiency, reducing the power consumption of data sending equipment and data receiving equipment and improving user experience.
As an alternative embodiment, the data transmitting apparatus 1520 is further configured to turn off the first transmitting device 15201 after establishing the first connection with the data receiving apparatus 1540, until the first transmitting device 15201 is turned back on after receiving the data transmission request next time; the data receiving apparatus 1540 is further configured to close the first receiving device 15401 after establishing the first connection with the data sending apparatus 1520 successfully, and to reopen the first receiving device 15401 until the next time a pairing request of the data sending apparatus 1520 is received.
The file transfer control system according to this embodiment opens the first transmitting device 15201 and the first receiving device 1540 only when the first connection between the data transmitting apparatus 1520 and the data receiving apparatus 1540 is established, and closes the first transmitting device 15201 and the first receiving device 15401 immediately after the first connection between the data transmitting apparatus 1520 and the data receiving apparatus 1540 is successfully established by using the first transmitting device 15201 and the first receiving device 1540 1. In the file transfer control system of this embodiment, the second transmitting device 15203 and the second receiving device 15403 are controlled to be turned on only during file transfer and turned off after file transfer, so as to reduce the power consumption of the apparatus, and the first transmitting device 15201 and the first receiving device 15401 are controlled to be turned on only when the connection between the data transmitting apparatus 1520 and the data receiving apparatus 1540 is established, so that the power consumption of the data transmitting apparatus 1520 and the power consumption of the data receiving apparatus 1540 can be further reduced, the standby time of the data transmitting apparatus 1520 and the data receiving apparatus 1540 can be further prolonged, and the technical effect of improving the user experience can be achieved.

The third transmitting device 15205 and the third receiving device 15405 in this embodiment are substantially the third communication devices in this embodiment. Alternatively, the third transmitting device 15205 and the third receiving device 15405 may be NFC chips, WIFI chips, or the like.
If it is detected that the first transmitting device 15201 is out of order, the data transmitting apparatus 1520 switches to initiate a connection request using the second transmitting device 15203 or the third transmitting device 15205, so that the data transmitting apparatus 1520 establishes a connection with the data receiving apparatus 1540. If it is detected that the second transmission means 15203 has failed, the data transmission apparatus 1520 switches to transmit the file to be transmitted to the data reception apparatus 1540 using the third transmission means 15205.
The file transmission control system according to this embodiment, by adding the third transmitting device 15205 and the third receiving device 15405, avoids the problem that the establishment of the first connection and the establishment of the second connection between the data transmitting apparatus 1520 and the data receiving apparatus 1540 are affected when the first transmitting apparatus 15201 or the second transmitting apparatus 15203 fails, and fully ensures the reliability of file transmission. Meanwhile, the file transfer control system of this embodiment selects the communication device used in establishing the first connection and the second connection between the data transmitting apparatus 1520 and the data receiving apparatus 1540 in an alternative manner, so that the power consumption of the data transmitting apparatus 1520 and the data receiving apparatus 1540 can be effectively reduced, the standby time is prolonged, and the use experience of the user is further improved.
As an optional embodiment, the data sending device 1520 of this embodiment may be further configured to, after the data receiving device 1540 is successfully connected, identify a distance between the data sending device 1520 and the successfully paired data receiving device 1540, and receive a touch signal input by the user when the identified distance is within a preset distance, where the touch signal is a signal generated when a touch interface of the data sending device 1520 receives a predetermined gesture operation, and the touch signal is used to trigger the data sending device 1520 to send a file to be transmitted to the data receiving device 1540.
