and when i is looped from 1 to N, receiving the N groups of data messages.
4. The method of claim 1, wherein reading a target memory data block from the RAM memory and mapping the target memory data block to a usb disk file comprises: and mapping the target memory data block into a USB flash disk file in a zero copy mode.
5. The method of claim 1, wherein the encoding the USB disk file to obtain encoded USB data comprises: and encoding the data in the USB flash disk file by adopting an inverse non-return-to-zero inversion encoding algorithm to obtain the encoded USB data.
6. The method according to claim 1, wherein the method further comprises:
if the target data is an electronic key signal, a first channel conversion instruction is acquired, and after the first channel conversion instruction is acquired, the electronic key signal is converted into a first I2C signal; or (b)
If the target data is an IC card signal, a second channel conversion instruction is acquired, and after the second channel conversion instruction is acquired, the IC card signal is converted into a second I2C signal;
and sending the first I2C signal or the second I2C signal to the data resource guarantee equipment so as to finish transparent transmission between target data and the data resource guarantee equipment.
7. Before receiving the target data transmitted by the external data resource storage device, the method further comprises:
acquiring a data transmission instruction, and performing fault self-checking based on the data transmission instruction to obtain self-checking information;
judging whether transmission faults exist or not according to the self-checking information;
if yes, generating alarm information, otherwise, executing the data transmission instruction, and receiving the target data transmitted by the external data resource storage equipment.
8. A data resource conversion device, comprising:
the data receiving unit is used for receiving target data transmitted by an external data resource storage device and storing the target data into the RAM in a memory data block mode, wherein the external data resource storage device comprises a storage device with an aviation interface;
the data conversion unit is used for reading a target memory data block from the RAM, and mapping the target memory data block into a U disk file, wherein the target memory data block is a memory data block corresponding to the target data;
the encoding unit is used for encoding the USB flash disk file to obtain encoded USB data;
and the sending unit is used for transmitting the encoded USB data to the data resource guarantee equipment through a USB bus so as to finish the data transmission of the target data in the external data resource storage equipment after the transmission is finished.
9. An electronic device, comprising: a memory, a processor and a transceiver in communication with each other in sequence, wherein the memory is configured to store a computer program, the transceiver is configured to send and receive messages, and the processor is configured to read the computer program and perform the data resource conversion method according to any one of claims 1 to 7.
