Figure；
Fig. 2 is a kind of data transfer flow of safe ECG Data Transmission Based card-reading apparatus in the utility model embodiment
Schematic diagram.
Embodiment
The utility model is described in detail below with reference to embodiment shown in the drawings.But these embodiment party
Formula is not intended to limit the utility model, structure that one of ordinary skill in the art is made according to these embodiments, method or
Conversion functionally is all contained in the scope of protection of the utility model.
A kind of embodiment of the present utility model presented below：
Refer to Fig. 1, a kind of safe ECG Data Transmission Based card-reading apparatus, including USB interface and circuit main board, the electricity
Road mainboard includes master controller, data transmission module, power module and SD card reading modules；
The power module electrically connects (power taking) with the USB interface, for for the master controller, data transfer mould
Block, the power supply of SD card reading modules；
The signal input part of the master controller is connected with the SD card reading modules electric signal, to pass through the SD Card Readers mould
Block reads the original electrocardiographicdigital data stored in SD card；
The signal output part of the master controller is connected with the data transmission module electric signal, to be passed by the data
Electrocardiogram (ECG) data by the master controller compression, encryption is delivered to the USB interface by defeated module.
It should be noted that there is compression algorithm program and cryptographic algorithm process, the compression algorithm program in master controller
It is existing program with cryptographic algorithm process, the utility model is not related to the improvement to algorithm routine in itself.
It is known, in cryptographic algorithm process implementation procedure data can be verified, so as to by virus, wooden horse with it is useful
Data field separates, and then prevents virus, wooden horse to be transfused in ecg analysis system.
Further, the power module includes LDO power supply chips, to be used as power management chip group.
The type of USB interface uses HID types in the present embodiment, altogether dispenses with driving, further increases data
The safety and stability of transmission.
Master controller is NXP LPC18xx serial, and the data-interface in SD card reading modules is SDIO interface protocols.
Fig. 2 is referred to, SD card is inserted into SD card reading modules, the original electrocardiographicdigital data in SD card pass through SD card reading modules
SDIO interfaces are read by master controller；Master controller is by the electrocardiogram (ECG) data read by compression algorithm and the place of AES
Reason, is transmitted into the ecg analysis system of computer by USB HID interfaces；Ecg analysis system passes through the electrocardiogram (ECG) data received
Original electrocardiographicdigital data are reverted to after crossing decryption and decompression, for subsequent analysis processing.Whole data transfer flow realizes the original heart
The lossless transmission of electric data safety.
Electrocardiogram (ECG) data is being transmitted to the signal of USB interface again to data transmission module again by SD card reading modules to master controller
Data can also be verified in communication process, so as to which virus, wooden horse and useful data field be separated, and then prevent it is viral,
Wooden horse is transfused in ecg analysis system.
It is of the present utility model to have technical effect that relative to prior art：
The utility model is connected with being mounted with the computer of ecg analysis system by USB interface and uses master controller to original
Beginning electrocardiogram (ECG) data is encrypted, and has the advantages of reading data safety.
Finally it should be noted that：Embodiment of above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to aforementioned embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing each embodiment, or special to which part technology
Sign carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from each reality of the utility model
Apply the spirit and scope of mode technical scheme.
