Research On Distribution Network Management System Architecture And Key Technology

Distribution is the sale mode commonly adopted by most domestic manufacturing enterprises of production-supply-marketing, and more and more enterprises established a certain size of distribution network. Enterprises can access to terminal business information at all levels of distributors and retailers through distribution network timely, so as to they can make the right decisions in time.However, most of the current distribution networks are with the characteristics of geographical dispersion, wide distribution and communications network vary the condition at all levels (for example, some countries, townships may not have the open network), etc., traditional fixed network-based distribution management system used in some limited distribution terminal. According to the characteristics of distribution network, we need to build a network management system to resolve the existence of the traditional network issues such as geographical constraints. M-commerce-related technologies and rapid development make a very good technical support to solve this problem. In this paper, based on the characteristics of distribution network, combined with mobile commerce technology, advances a distribution network management system architecture based on fixed and mobile networks, and analysis and research the mobile communication of the architecture. The system can be a good solution to the distribution terminal difficult issues such as data acquisition and have characteristics of low cost, strong transplantation. The paper includes the following:1. Advances a distribution network management system architecture based on fixed and mobile networks, and analysis the architecture. Comparative analysis of the mobile business in several commonly used access technology, according to the distribution industry and the characteristics of distribution networks, advances mobile terminal using SMS messaging manner and based on the J2ME platform for the development of good to the enterprise application interface to provide users with a good user experience.2. A more detailed analysis and research the way of the mobile communications of the architecture in the distribution network management system, mainly related to the following aspects: resolved the communication message format definition and resolution of issues between the two sides; SMS communications, such as hair loss or abnormal circumstances, the use of text messages according to their type of business will be the difference between the importance of the solution to deal with; the security issues involved in the distribution network management system : using static double identity authentication solution to resolve the identity authentication problem; using the open source J2ME encryption package in the Bouncy castle to achieve certification to send encrypted messages to achieve the purpose of data integrity checking; analyzed the security of the J2ME platform technology of the terminals of the system technology. Also analyzed the storage of data records of J2ME,and applications the index into the data record for storage.3. According to the architecture of thinking, combined with a motorcycle actual needs of enterprises in Chongqing, in the mobile terminal developed based on the J2ME platform, in the Web server-side development using J2EE architecture and achieve a J2ME + J2EE distribution network management system, practice has proved that the system has the characteristics of the portability, lower cost, and easy to operate.
