Design And Implementation Of ONECONN Platform Data Service System

The topic of this paper is selected from cooperation projects between Shenzhen A Intelligent Technology Co., LTD and our intelligent information processing laboratory team, aiming to set up a data access system that combined with a global equipment platform. At present, the company has independently developed a variety of logistics equipment monitoring systems. With the expansion of business, so many similar monitor management systems are developed, but some of their business functions are overlaps. Due to the staff turnover, these systems are realized by adopting different communication protocols and different technology, which causing troubles to the to the expansion of business. These problems drive up the cost of development of the system maintenance. With the needs of the international logistics transportation monitoring, the company needs to be accessed with a global news communication system that is all-weather and can support different environment. Therefore, CIMC hopes to integrate and migrate many of their logistics equipment monitoring platforms, design and implement a new platform, which called ONECONN Platform. I was responsible for the design and implementation of ONECONN Platform data service system.Based on CIMC’s forms of business and business needs, this paper points out that there are three problems of the existing systems: 1) server architecture problem- the system module partition are fuzzy, coupling between modules are serious, and business code overlaps are high; 2) data communication link access problem- the system of data communication link has strong dependence, and no unified standard treatment for heterogeneous data sources;3) the lack of global data communication services.Based on the problems mentioned above and the requirements of ONECONN Platform, this paper elaborats the design of the data service system of ONE Platform in detail. In the light of the problem of server architecture, this paper designs and implements two server arthitectures, one of which is the synchronous/half reactive thread pool communication architecture based on the ACE_Task and the other is Flow –Framework business logic architecture. These two server arthitectures provide the server system with a clear hierarchy architecture; To the data communication link access problem, middleware subsystem is designed and implemented, so it can be effectively access to a variety of data communication link and heterogeneous data sources equipments; Implementing the access of ORBCOMM satellite communication link, the system can provide global data communication services; In order to meet the needs of users, the mobile Internet applications system is realized and an intelligent mobile terminal APP products are provided, so the users are able to effectively manage and monitor the logistics equipment.This system has a high commercial value, which makes the data services and business application completely separated. As long as the corresponding data resolution protocol is developed, it can access the logistics equipment to the system; And the distinct server architecture provides the system with high expansibility and practicability.
