| Whom this text tell in give a Yunnan tobacco re-drying enterprise develop smoke-box bale section case some problems and solutions that tobacco leaf find of the information management system course. The main content tell that utilize Power builder database application program developing platform associate with Dream Weaver web page making flat to develop C/S configuration combine B/S configuration with jointly information management system and label printing at intelligence for method and technology relevant mains of application.The paper told that the development course of the database and main characteristic of the technical development of the database of each stages, and they have recommended and compared, analyzed separately. In addition, paper make a description of generality to whole group network way and two pluses and minuses and pluses and minuses of different network way of the group of developing platform of system. The key part of the article is to the explanation of the main technology used in project implementation. Including: Data gather technology, divide into gather with temperature, moisture datum gathering two parts for weight data;Keep in technology is to utilize two thing target join two different database at the same time, and detailed narration how declare thing target and need item that notice;The controlled module mainly told how to utilize the computer now of a bunch of cause for gossip of the PC to the flexible control that made of industry electricity, and how to make use of formation principle of the array to realize the tare of the smoke box and one-one method of gross weight;Preventing the illegal shut-down module from telling structural body and self-defining user's target definition , statement, operation method , and how to utilize PB to transfer Win32 function and realize passing the automatic shut-down of computer control, it causes the losing of the damage of the operating system and production data to prevent workers from shut down illegally. In addition, this text utilize greater space tell in with Dream Weaver two big problems that should notice make B/S structural application program, too. One is installation of plug-in package that the operating system must be installed while making B/S structural application program;One is item and solution that the aptest to go wrong database should be paid attention to while joining while doing B/S structure.The implementation of this project still belongs to the first time in the nationaltobacco trade. The main one is that have solved the gross weight and tare of tobacco leaf of casing one-one problem, and make tobacco re-drying enterprise's encasement tobacco leaf weight error to limit to ± 50g, solve encasement tobacco leaf weight error loud difficult problem completely. Moreover, because the key data of the whole system is gathered and finished automatically by the computer, the ones that made the hydraulic pressure bale automatic intensity of the section had reached the promotion by a large margin. In addition, all craft parameters of encasement tobacco leaf file is put in the database and recorded, and has carried on bar code management. It offered the reliable basis for the fact that the trail of quality the tobacco leaf after the tobacco leaf is dispatched from the factory. After whole system is brought into operation operation, make the management of the re-drying enterprise finished managerial get a new height. The elegant and decent glue bar code label make the management of the tobacco leaf both more convenient with using. It get well received by user!... |
