Embodiment Construction

[0016] Such as figure 1 and figure 2 The system for compressing received e-mails based on the LZW compression algorithm is characterized in that it comprises the following steps:

[0017] 1) Real-time monitoring of whether the computer central processing unit has issued an instruction to receive emails inward through the receiving email identification unit;

[0018] 2) Once the receiving e-mail identification unit finds that the computer central processing unit has made an instruction to receive e-mails inwardly, it sends a signal to notify the active unit;

[0019] 3) The main control unit automatically establishes a connection with the computer central processing unit, retrieves the emails to be received by the computer central processing unit, and then sends them to the LZW compression unit for compression processing;

[0020] 4) Finally, the main control unit feeds back the compressed email to the computer central processing unit, and the computer central processing uni...

Abstract

The invention discloses a received electronic mail compression system based on the LZW compression algorithm. The compression system is characterized in that the compression comprises the following steps: 1) real-time monitoring is performed on the condition whether a computer central processing unit makes an instruction of receiving an electronic mail to the inside or not through a received electronic mail identification unit; 2) once the received electronic mail identification unit finds that the computer central processing unit makes the instruction of receiving an electronic mail to the inside, a signal is sent to notice a master control unit; 3) the master control unit establishes connection with the computer central processing unit automatically to obtain the electronic mail that the computer central processing unit is about to receive and then send the electronic mail to a LZW compression unit for compression; 4) and finally, the compressed electronic mail is fed back to the computer central processing unit by the master control unit for further being processed by the computer central processing unit. The method provided in the invention has advantages, such as convenient utilization, fast processing speed, easy technology implementation, etc.

Description

technical field [0001] The invention relates to a system for compressing received emails based on an LZW compression algorithm. Background technique [0002] With the general promotion of enterprise modernization, paperless office has been accepted by more and more enterprises because of its advantages such as high office efficiency, convenient file transfer, resource and cost saving. It is precisely because of its convenient file transfer feature that the requirements for enterprise data space are greatly increased. [0003] Especially for emails received by enterprises, if the content is compressed, the office personnel of the enterprise need to manually compress the transmission content. Today, efficiency is the first priority, and it is almost impossible to require the possibility of compressing every file. . Therefore, a system capable of compressing received e-mails by itself needs to be developed urgently. [0004] The LZW algorithm is a popular variant of LZ78, de...
