Problems solved by technology

As watches become more and more intelligent, the application requirements for external transmission of watch data (such as positioning data, etc.) are also becoming stronger and stronger. However, the current transmission methods are still dominated by USB wired communication or Bluetooth wireless communication. The former Although the data transmission is safe and reliable, it requires an additional USB transmission line, which is inconvenient to use. Although the latter is convenient, the security of data transmission is poor, easy to be stolen and interfered, and there is also the problem of limited transmission distance (Bluetooth Communication is generally only a few meters)

Embodiment 1

[0020] figure 1 It shows a schematic flow chart of the safe wireless transmission method of watch data provided by the present invention. The secure wireless transmission method of watch data provided by this embodiment includes the following steps.

[0021] S101. Listen to the communication handshake channel, and discover the transmission target in the following manner: receiving a beacon frame from the transmission target, or receiving a probe response frame from the transmission target after sending a probe frame on the communication handshake channel.

[0022] In the step S101, the communication handshake channel is a dedicated channel for two communication terminals (such as a smart watch and a smart phone) that are preparing to wirelessly transmit watch data to discover each other and exchange relevant message frames to achieve a communication handshake. It is at a different frequency from the subsequent data transmission channel. For example, when the transmission freq...

Embodiment 2

[0033] figure 2 It shows a schematic structural diagram of the improved security wireless transmission device for wrist watch data of the present invention. The difference between this embodiment and Embodiment 1 is that a transmission device for implementing the technical solution of Embodiment 1 is provided, including: a detection unit, configured to listen to the communication handshake channel, and discover the transmission target in the following manner: The beacon frame of the transmission target, or after the detection frame is sent on the communication handshake channel, the detection response frame from the transmission target is received; the synchronization unit is used to exchange message frames with the transmission target on the communication handshake channel, and synchronize the two sides A frequency hopping sequence cyclic code; an encapsulation unit for encapsulating the watch data to be transmitted into several data frames to be transmitted sequentially, an...

Abstract

The invention relates to the field of a wearing device and discloses a secure wristwatch data wireless transmission method and transmission device. According to the method, wristwatch data is wirelessly transmitted in a frequency hopping mode, in this way, on the basis of facilitating data transmission, the data is not liable to be stolen and interfered in a transmission process, the data transmission security is ensured, and the wireless transmission distance is expanded, even to the hectometer level distance.

Description

technical field [0001] The invention relates to the field of wearable devices, in particular to a safe wireless transmission method and transmission device for watch data. Background technique [0002] A wristwatch is a wearable device that is worn on the wrist and is used primarily for timekeeping and / or direction indication. With the development of electronic technology, more and more functions are integrated into existing watches, such as satellite positioning and mobile calls. As watches become more and more intelligent, the application requirements for external transmission of watch data (such as positioning data, etc.) are also becoming stronger and stronger. However, the current transmission methods are still dominated by USB wired communication or Bluetooth wireless communication. The former Although the data transmission is safe and reliable, it requires an additional USB transmission line, which is inconvenient to use. Although the latter is convenient, the securi...
