In recently years,people have paid much attention to the research of self-encoded in the spread spectrum communication system and gotten certain achievements.

While self-encoded spread spectrum communications(SESS) improve the concealable performance of communicating signals,they still maintain the anti-jamming ability of direct sequence spread spectrum communications.

During working out the group encoding system, the characteristics of application system and integration requirements for CAD, CAPP, PDM, ERP, automatic encode and so on should be considered, in addition to the figures of the parts and components.

An automatic coding system based on Pro/Toolkit was displayed,which could code the designed products automatically.

The design consideration,primary functions and database structure of general examination items library are expounded,and the concepts of "automatic coding”,“knowledge point”are used to the repeated problems of same knowledge items and a solving way is given,The background of class item generation ,function characteristics and developing environment are analysized.

In order to overcome the disadvantages of highe error rate and heavy task,the present paper developed the edible oile recall system based on automatic coding trigger,which used to menage the information of edible oil automatically .

By analyzing current status and implementation requirements of auto coding technology in GIS and data sharing, this paper points out that there are two urgent requirements needs for GIS and data sharing .

Study on the Standardization of Network Agricultural Information and Autocoding Register System Development;

For this reason, we propose two methods, one is natural coding .
