[0034] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0035] See also Figure 1 , a data transmission method provided by an embodiment of the present invention, such as Figure 1 As shown, the method may include:

[0036] S101: Obtain a target encryption algorithm sent by a receiving and control unit; the target encryption algorithm is randomly generated by the receiving and control unit; in specific implementation, the embodiment of the present application may also provide that the encryption algorithm includes a frame sequence number, a timestamp, and an encryption format. The encryption format includes random padding data, padding length, and padding position.

[0037] S102: acquiring real data by a data acquisition component and storing the real data in a storage module;

[0038] S103: encrypting the real data using the target encryption algorithm to obtain encrypted data;

[0039] S104: Send the encrypted data to the receiving and control unit so that the receiving and control unit uses the target encryption algorithm to decrypt the encrypted data to obtain the real data.

[0040] In order to realize jump transmission, the embodiment of the present application can also provide receiving a data jump transmission instruction sent by the receiving and control unit, so as to send corresponding data to the receiving and control unit according to the data jump transmission instruction. The data jump transmission instruction includes a jump format.

[0041] The method provided in the embodiment of the present application is mainly undertaken by the processing module of the processing unit. When it is specifically implemented, see Figure 2 , Figure 3 , Figure 4 The processor module can be any processor circuit with processor capabilities, and the processor module mainly implements data collection, encryption processing, and data transmission processing.

[0042] The encryption processing of data, the encryption method in the processing module is provided by the receiving and control unit (dynamically configurable or fixedly configured). An encryption algorithm is preset in the receiving and control unit to encrypt and store the collected data. The algorithm contains frame sequence number, timestamp, encryption format, and real data. The encryption format is set by the receiving control unit. After the device is started, the random encryption format of the data (random fill data, fill length, fill position and other information) is sent to the processing module. The processing module receives the encryption format, encrypts the data and sends it to the receiving and control unit (the encryption format is determined by the receiving control unit. The encryption format is dynamic and can effectively prevent being cracked.

[0043] At the same time, the total frame sequence number length of the encrypted frame can be defined, and after definition, it is sent to the processing module, and at the same time, it is marked and stored in the receiving processing module control unit for easy data parsing. In addition, the receiving and control unit can also control the jump transmission of data, for example: requiring the processor control module to only send data with an odd frame sequence number and discard data with an even frame sequence number (or requiring to jump from frame sequence number 1 to 10 for transmission, etc., the jump format is controlled by the receiving control unit).

[0044] Data storage mainly refers to the data received by the module, which is stored in the buffer dynamic storage module DDR, and is encrypted as described above in the processing module before sending the data to the receiving and control unit.

[0045] The data collection module refers to certain collected data in the physical object, such as radar data, which is processed by the processor unit and then sent to the receiving and control unit.

[0046] In summary, the data transmission method provided by the present application encrypts the collected data by receiving and controlling the target encryption algorithm randomly generated by the control unit, thereby ensuring that even if the data is intercepted during transmission, the difficulty of cracking will be greatly increased because the traditional fixed encryption algorithm is not adopted, thereby increasing the reliability and security of the data transmission process.
