Both are carried out logical operation, obtaining final logic operation result is by breath：Q1, Q2, Q3, Q4......Qn；
Step S1.5：The result of logical operation is reduced to piece image by remote terminal, and the image information and original image are believed
Breath is sent to data transmission unit.
5. the communication means of data transmission unit as claimed in claim 4 and remote terminal, it is characterised in that the step S3
In, the method that the instruction received is decrypted the data transmission unit includes：
Step S3.1：Data transmission unit carries out image segmentation to the image information received, then carries out binaryzation；It is meanwhile right
After the original image information received carries out image segmentation, then carry out binaryzation；
Step S3.2：To the original image information after image segmentation and binary conversion treatment and the decryption after image segmentation and binaryzation
Image information afterwards, correspond and carry out logic inverse operation, obtain several intermediate results；
Step S3.3：Several intermediate results are connected into the result of final decryption, the instruction after being decrypted.
6. the communication system of a kind of data transmission unit and remote terminal, it is characterised in that the system includes：
Terminal handler：Instructed for generating, be sent to data transmission unit；The finger that response data transmission unit sends over
Order；
Terminal encryption module, for the instruction of generation to be encrypted；

Arithmetic element, for carrying out logical operation to the image after the instruction after coding and fractionation and segmentation and binaryzation；
First information converting unit, for the result after logical operation to be converted into image information；
Data outputting unit, for exporting the result after encrypting.
8. the communication system of data transmission unit as claimed in claim 7 and remote terminal, it is characterised in that the decryption is single
Member includes：
Data input cell, for input image information and original image information；
Second information conversion unit, for converting image information into binary message；
Image segmentation unit, for splitting to original image information；
Flash memory, for interim storage intermediate data；
Image binaryzation unit, for carrying out binary conversion treatment to original image；
Inverse operation unit, for the original image information after image information and binaryzation to be carried out into logic inverse operation；
Inverse transform unit is encoded, for binary-coded information to be converted into the command information of segmentation；
Connection unit is instructed, for the instruction after segmentation to be attached, generates complete command information.
