Based on the above hardware structure, an embodiment of the data transmission method of the present invention is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a data transmission method according to the present invention, where the method is used for a mobile terminal, and the method includes the following steps:
step S11: and when detecting that the distance between the target terminal equipment and the target terminal equipment is smaller than or equal to the preset distance, establishing connection with the target terminal equipment and acquiring a trigger signal.
Step S12: and acquiring first data to be transmitted based on the trigger signal.
Step S13: and converting the first data to be transmitted into first millimeter wave data.
Step S14: and sending the first millimeter wave data to the target terminal equipment so that the target terminal equipment restores the first millimeter wave data into the first data to be transmitted.
It should be noted that the execution subject of the present invention is a mobile terminal, the mobile terminal is installed with a data transmission program, and when the mobile terminal executes the data transmission program, the data transmission method of the present invention is implemented. The mobile terminal generally has a CPU (central processing unit, herein named first control chip) for performing step S12 of the present invention and a millimeter wave chip (herein named first millimeter wave chip) for performing steps S11, S13 and S14 of the present invention.
In addition, the target terminal device may be a personal host, a notebook computer or other terminal device, and the target terminal device also has a CPU (named as a second control chip) and a millimeter wave chip (named as a second millimeter wave chip), where the second millimeter wave chip is used to establish a connection with the first millimeter wave chip when the distance between the target terminal device and the mobile terminal is less than or equal to a preset distance, so as to implement the connection between the target terminal device and the mobile terminal, and the second millimeter wave chip is further used to restore the first millimeter wave data to the first data to be transmitted. When the distance between the target terminal device and the mobile terminal (actually, the distance between the first millimeter wave chip and the second millimeter wave chip) is less than or equal to a preset distance, the first millimeter wave chip and the second millimeter wave chip are automatically connected, wherein the preset distance may be 2-4 cm. By setting a smaller preset distance, the connection between the millimeter wave chip with a longer distance and the first millimeter wave chip of the mobile terminal is avoided, and the pertinence of data transmission, the stability and the non-conflict of equipment connection are ensured.
In a specific application, the first data to be transmitted may be any form of data to be transmitted, and the present invention is not limited thereto. The data format of the first data to be transmitted cannot be directly sent by the first millimeter wave chip of the mobile terminal, and the first millimeter wave chip of the mobile terminal is required to convert the data into the first millimeter wave data so as to send the first millimeter wave data. When the trigger signal is obtained, the mobile terminal usually pops up a prompt message "whether data transmission is needed or not when the mobile terminal is connected with the target terminal device", and at this time, the corresponding first data to be transmitted is obtained based on the selection operation of the user for the prompt message. The millimeter wave chip of the present application may be any form of millimeter wave chip, and the present invention is not limited thereto.
Further, the method further comprises: receiving second millimeter wave data sent by the target terminal device, wherein the second millimeter wave data is obtained by converting the obtained second data to be transmitted; and restoring the second millimeter wave data into the second data to be transmitted.
It can be understood that, in the same manner as in steps S11-S14, the target terminal device may obtain the second data to be transmitted, and the mobile terminal receives and restores the second data to be transmitted, so as to implement mutual data transmission between the mobile terminal and the target terminal device.
The target terminal equipment and the mobile terminal realize wireless and rapid data transmission by utilizing millimeter waves, and a data transmission interface (serial port) and a data line (serial port line) are not required to be arranged on the target terminal equipment and the mobile terminal, so that the design and manufacturing costs of the target terminal equipment and the mobile terminal are saved, and the portability of the mobile terminal is improved.
Further, step S13 includes: when the first millimeter wave data is sent to the target terminal equipment, if the second millimeter wave data sent by the target terminal equipment is received, the first millimeter wave data is sent to the target terminal equipment in a time division multiplexing mode.
Further, before step S12, the method further includes: sampling the first data to be transmitted to obtain sampling data; encoding the sampled data to obtain encoded data; accordingly, step S12 includes: converting the encoded data into first millimeter wave data; accordingly, step S14 includes: and sending the first millimeter wave data to the target terminal equipment so that the target terminal equipment restores the first millimeter wave data into the encoded data, decodes the encoded data to obtain the sampling data, and reconstructs the sampling data to obtain the first data to be transmitted.
Specifically, the step of sampling the first data to be transmitted to obtain sampled data includes: when the first data to be transmitted does not have a synchronous clock, sampling the first data to be transmitted by using a high-speed clock to obtain sampled data; or when the first data to be transmitted has a synchronous clock, sampling the first data to be transmitted by using the synchronous clock to obtain sampled data.
It should be noted that "sampling the first data to be transmitted" is performed to obtain sampled data; and correspondingly, decoding the coded data to obtain the sampled data, and reconstructing the sampled data to obtain the first data to be transmitted is used as a second control chip of the target terminal equipment. Step S12 is executed to obtain a first millimeter wave chip, and step "reconstruct the sample data to obtain the first data to be transmitted" is executed to obtain a second millimeter wave chip.
The technical scheme of the invention provides a data transmission method for a mobile terminal, which comprises the following steps: when detecting that the distance between the target terminal equipment and the target terminal equipment is smaller than or equal to a preset distance, establishing connection with the target terminal equipment and acquiring a trigger signal; acquiring first data to be transmitted based on the trigger signal; converting the first data to be transmitted into first millimeter wave data; and sending the first millimeter wave data to the target terminal equipment so that the target terminal equipment restores the first millimeter wave data into the first data to be transmitted.
In the existing data transmission method, a serial port of a mobile terminal is connected with a serial port of a terminal device through a serial port line, and a user needs to carry the serial port line when data transmission is carried out, so that the portability of the mobile terminal is poor. According to the data transmission method, the first data to be transmitted is converted into the first millimeter wave data, the first millimeter wave data is transmitted in a wireless mode, and a user can be connected with the mobile terminal and the terminal device without carrying a serial port line and can transmit data. Therefore, the data transmission method of the invention has better portability of the mobile terminal.
Meanwhile, in the existing data transmission method, the serial ports and serial port lines of the mobile terminal and the terminal equipment can be mechanical structures with higher precision, data transmission is carried out in a serial port mode, and the transmission speed is lower.
