Abstract:: A data transmission system design of intelligent housekeeper based on non-orthogonal frequency division multiplexing is proposed.The program of PCIE internal structure controls the direction of data flow to divide the reading operation and writing operation of the system.Data transmission deviation is reduced according to preprocessing operation.The subcarrier modulation signal of non-orthogonal frequency division multiplexing technology is used to improve the frequency utilization and reduce the system data transmission deviation.Through equipment acquisition , the data type is obtained and the corresponding general data transmission mode is selected.The elliptic curve cryptography and advanced encryption standard are used to resist the data tampering attack of the intelligent electric housekeeper , and the encryption reverse operation and authentication signature are used to decrypt the ciphertext to maintain the data security , so as to realize the safe data transmission of the intelligent electric housekeeper.The simulation results show that the system has strong data transmission timeliness , high throughput and low packet loss rate ,? ?and has strong practicability.It deeply optimizes the popularization and application of intelligent electric housekeeper system.
