< method examples >
Because the existing portable devices such as the wrist-worn device and the like generally have a small memory, for example, only M data packets transmitted for one data request can be stored, and data transmission between the wrist-worn device and the service terminal is in a serial manner, and is based on the request of the wrist-worn device, the service terminal only responds and replies data, and the service terminal does not actively transmit data to the wrist-worn device when the data request of the wrist-worn device is not received. Therefore, in a case that the wrist-worn device and the service terminal perform data interaction, generally, the wrist-worn device sends an instruction for requesting first data to the service terminal, the service terminal responds and replies M data packets for the first data request, after the wrist-worn device receives the M data packets replied by the service terminal, the wrist-worn device processes the first data, and at this time, the service terminal waits for the instruction for requesting second data of the wrist-worn device. And after the wrist-worn device finishes processing the first data, the wrist-worn device sends a request instruction of second data, the service terminal responds and replies, and the data interaction process is carried out in a circulating manner. Fig. 2 is a schematic flow chart illustrating data interaction between the conventional wrist-worn device 200 and the service terminal 300.
In the above interaction flow, when the wrist-worn device processes the first data, the service terminal is in an idle waiting state, and when the wrist-worn device processes the first data and sends the second data request, the service terminal does not start interacting with the wrist-worn device, which is not beneficial to the utilization of the service terminal. The method mainly utilizes the waiting time of the service terminal by expanding the memory of the wrist-worn device and optimizing the data request instruction sending time of the wrist-worn device, thereby improving the effect of short-distance protocol transmission of big data between the wrist-worn device and the service terminal.
As shown in fig. 3, the data transmission method according to an embodiment of the present invention may include the following steps S310 to S340:
step S310, processing the N-1 data stored in the memory.
In order to improve the transmission efficiency and fully utilize the waiting time of the service terminal, the memory of the wrist-worn device can be firstly expanded to the original fixed multiple, for example, the original memory can store M data packets, and the memory is expanded to store 2M data packets. Therefore, the nth-1 data is referred to as the nth data and the (N + 1) th data, and refers to three data that exist sequentially, wherein the nth-1 data and the nth data may be stored at the same time on the wrist-worn device side, and similarly, the nth data and the (N + 1) th data may also exist at the same time.
In this embodiment, before the processing the N-1 th data stored in the memory, the method further includes sending an N-1 th instruction requesting transmission of the N-1 th data to the service terminal; receiving and storing in the memory the N-1 th data transmitted by the service terminal in response to the N-1 th instruction; wherein the N-1 data is transmitted by the service terminal through at least one data packet; and sending an Nth instruction for requesting to transmit the Nth data to the service terminal at a second preset time in the process of receiving and storing the N-1 th data in the memory. For example, the wrist-worn device is a smart watch, and sends an instruction for requesting transmission of a specific song to a smart phone in a bluetooth mode.
In this embodiment, when the service terminal replies to the N-1 th command transmission request, the service terminal may reply the command response message first and then transmit the data packet of the N-1 th data.
In one embodiment, the second predetermined time is a time point when the first data packet of the N-1 th data is received and stored in the memory by the wrist-worn device. In order to improve the utilization rate of the service terminal and reduce the idle waiting time of the service terminal, the wrist-worn device sends an Nth instruction for requesting to transmit the Nth data to the service terminal when receiving and storing a first data packet of the Nth-1 data. The selection of the instruction sending time can greatly improve the utilization rate of the service terminal, and the service terminal receives the Nth instruction request for requesting to transmit the Nth data after the transmission of the first data packet of the Nth-1 data. Therefore, after the service terminal finishes transmitting all data packets of the (N-1) th data, the service terminal can immediately respond to the (N) th instruction request and transmit the data packets of the (N) th data.
In another embodiment, the second predetermined time may be any time point between the receiving and storing of the first data packet of the nth data and the last data packet of the nth data by the wrist-worn device, and the nth instruction requesting transmission of the nth data is sent to the service terminal. In the embodiment, in the process of receiving the data packet of the nth-1 data, the wrist-worn device can send the nth instruction requesting to transmit the nth data at any time point after the start and before the completion of the receiving, so that the idle waiting state of the service terminal when the wrist-worn device sends the nth instruction requesting to transmit the nth data after the N-1 data is processed and completed can be avoided, and the file transmission efficiency is improved.
Step S320, receiving and storing the Nth data in the memory in the process of processing the N-1 th data; wherein the Nth data is transmitted by the service terminal through at least one data packet.
In the embodiment, in the process of processing the previous data, the next data is received and stored, so that the data transmission efficiency of the wrist-worn device and the service terminal is improved, and the idle waiting time of the service terminal is reduced.
In one embodiment, the nth data in step S320 is transmitted by the service terminal through at least one data packet having an identifier corresponding to the nth data.
In this embodiment, after the wrist-worn device receives the data packet corresponding to the nth data, because the utilization rate of the service terminal is improved, the data packets for the two data may be stored in the memory of the wrist-worn device at the same time. Thus, wrist-worn device differentiation is facilitated. The data packets of the nth data stored by the wrist-worn device are all provided with the identifiers corresponding to the nth data to mark that the data packets belong to the nth data, and for example, the identifiers can be offset addresses of the data packets and the like.
Similarly, after each data request, the data packet received and stored by the wrist-worn device has an identifier corresponding to the data, so as to distinguish the corresponding relationship between each data request and the received data packet, thereby facilitating the identification of the wrist-worn device.
Step S330, when the processing of the N-1 th data is completed, the processing of the N-1 th data is started continuously, and the memory space of the memory corresponding to the N-1 th data is released.
In this embodiment, after the wrist-worn device completes processing the N-1 th data, the nth data continues to be processed, and the memory releases the memory space corresponding to the N-1 th data, so that the memory has space to continue to receive and store the N +1 th data, and then the N +1 th data continues to be processed after the nth data is processed, thereby reducing the time for waiting for receiving and storing the N +1 th data, and improving the utilization efficiency of the device.
Step S340, sending an N +1 th instruction requesting transmission of an N +1 th data to the service terminal at a first predetermined time in the process of processing the nth data, and receiving and storing the N +1 th data transmitted by the service terminal in response to the N +1 th instruction in the released memory space; wherein the N +1 th data is transmitted by the service terminal through at least one data packet.
In this embodiment, in the process of processing the nth data by the wrist-worn device, that is, the N +1 th instruction transmission request of the N +1 th data is sent, and meanwhile, the data packet of the N +1 th data is stored in the space after the N-1 th data is released, so that the sending time of the data request instruction is advanced, which is beneficial to improving the utilization rate of the service terminal and the wrist-worn device, and avoiding the loss of data when the storage space is insufficient.
In one embodiment, in step S340, in the step of sending an N +1 th instruction requesting to transmit N +1 th data to the service terminal, the N +1 th instruction carries an identifier.
After the memory of the wrist-worn device is expanded to the original fixed multiple, each M data packets corresponding to two data can exist in the memory of the wrist-worn device at the same time, so that the wrist-worn device can distinguish which data packets correspond to one data and which data packets correspond to another data by using identifiers.
In this embodiment, the distinction can be made by attaching a flag to the (N + 1) th instruction of the (N + 1) th data. And after the service terminal receives the instruction request with the identification, correspondingly replying each data packet with the same identification. Therefore, when two different data packets corresponding to the data exist in the memory of the wrist-worn device at the same time, whether the data packet corresponds to the nth data or the data packet corresponds to the (N + 1) th data can be distinguished through the identification carried by each data packet.
The identification in the instruction identifies the instruction and the data packet sent by the service terminal, and simultaneously corresponds the data and the data packet through the identification according to the corresponding relation between the instruction and the data, so that the wrist-worn device can acquire the data packet corresponding to the data to be processed, and the efficiency is improved.
In one embodiment, the first predetermined timing in step S340 is a time point when the wrist-worn device starts to process the nth data. After the wrist-worn device finishes processing the (N-1) th data, the Nth data can be continuously processed, after the wrist-worn device starts to process the Nth data, an (N + 1) th instruction for requesting to transmit the (N + 1) th data is sent, the time for the wrist-worn device to process the Nth data is utilized to the maximum extent to transmit a data packet of the (N + 1) th data, the idle waiting time of the service terminal is shortened, the time for the wrist-worn device to wait for transmitting the data packet is shortened, and the utilization rate of the service terminal and the file transmission efficiency are improved.
In another embodiment, the first predetermined timing in step S340 may be any time point between the start of processing the nth data and the completion of the processing by the wrist-worn device. In this embodiment, in the process of starting processing the data packet of the nth data, the wrist-worn device may send the (N + 1) th instruction requesting transmission of the (N + 1) th data at any time point after starting processing and before finishing processing, which can reduce the idle waiting time of the service terminal and the data receiving time of the wrist-worn device when the wrist-worn device finishes processing the nth data and then sends the (N + 1) th instruction requesting transmission, thereby improving the file transmission efficiency.
A schematic flow chart of data interaction between the wrist-worn device 200 and the service terminal 300 according to the present invention in the latter embodiment is shown in fig. 4.
According to the data transmission method, the defects of low speed and poor user experience of short-distance transmission of the super-large files are effectively overcome, the resource utilization rate of the wrist-worn equipment and the service terminal is greatly improved, the data transmission can be improved by about one time under the condition of the best implementation mode, and the protocol-based transmission synergy of the super-large files is realized.
