Problems solved by technology

[0004] When the mobile terminal is used as a related product that requires high data integrity and real-time performance, it is difficult to ensure the batch quality of radio frequency communication due to the directionality, power level, and receiving sensitivity of the radio frequency signal, and because the radio frequency signal is easily interfered by environmental noise. In the process of data transmission, there is no loss of data or the confusion of front and rear data, which leads to the failure of data transmission, which affects the reliability of the RF mobile terminal in the actual application process

Embodiment 1

[0067] Please refer to figure 1 , Is a structural block diagram of an embodiment of the radio frequency transmitting terminal of this embodiment. The radio frequency transmitting terminal of this embodiment includes a main control module 101, a distance control module 102, and a radio frequency transmitting module. The radio frequency transmitting module includes a radio frequency sub-module 103 and a radio frequency antenna 104. The distance control module 102 is used to establish a connection with the radio frequency receiving terminal. Radio frequency wireless communication link; the main control module 101 is connected to the distance control module 102 to determine whether the bulk data to be transmitted exceeds the maximum amount of data that the radio frequency sub-module 103 can transmit at a time, and if so, the bulk data to be transmitted Divide into multiple data packets, and add identification sequence to the multiple data packets, including data packet identificatio...

Embodiment 2

[0075] Please refer to Figure 4 , Is a structural block diagram of an embodiment of the radio frequency receiving terminal of this embodiment. The radio frequency receiving terminal of this embodiment includes a main control module 401, a distance control module 402, and a radio frequency receiving module. The radio frequency receiving module includes a radio frequency sub-module 403 and a radio frequency antenna 404. The distance control module 402 is used to establish the radio frequency receiving terminal and The radio frequency wireless communication link between the radio frequency transmitting terminal; the radio frequency sub-module 403 is connected to the radio frequency antenna 404 for receiving the data packet stream sent by the radio frequency transmitting terminal through the radio frequency antenna 404, and the data packet stream contains PID and CRC Check; The main control module 401 is connected to the distance control module 402, and is used to unpack according ...

Embodiment 3

[0084] Please refer to Figure 8 , Is a flowchart of an embodiment of a method for transmitting bulk data through a radio frequency link in this embodiment. The method for transmitting bulk data on a radio frequency link in this embodiment includes the steps:

[0085] S801: Establish a radio frequency wireless communication link between the radio frequency transmitting terminal and the radio frequency receiving terminal.

[0086] S803: Determine whether the batch of data to be sent is greater than the maximum amount of data that can be transmitted by the radio frequency transmitting terminal at one time, and if so, execute step S805; otherwise, send the data in a normal sending mode.

[0087] Of course, in this embodiment, S803 can also be performed, that is, regardless of whether the batch of data is larger than the maximum amount of data that the radio frequency transmitting terminal can transmit at a time, it is divided into multiple data blocks, and the specific number depends on...

Abstract

The invention discloses a method and system for transmitting batch data through a radio frequency link. To-be-sent batch data is segmented into a plurality of data packets; an identification sequence is added to each data packet; a data packet stream is formed; when part of data is lost, the data packets are identified, so a sending end or a receiving end knows which part of data is lost according to the identification sequences; further corresponding strategies can be made for corresponding processing on the lost data; and the problem that the data transmission of this time is failed due to loss of part of data or front and rear data disorder is solved. According to the method provided by the invention, protocol data costs are low, and the transmission capability for the batch data through radio frequency is improved.
