Concurrent Multiprocess Application to Domestic Telecommunication System

As the national meteorological telecommunication center, Beijing Meteorological Telecommunication System (BMTS) is mainly responsible for the collection and dissemination of national meteorological data. With all kinds of means of exploration and products of weather service teeming, domestic meteorological telecommunication software cannot satisfy the meteorological data real time transmission needs, so meteorological data can not be used in time. Communication software is imperative to improve the ability to exchange information to meet the ever-increasing demand for the exchange of real-time weather information. Along with the computer technology development, the multi-advancements technology also obtained the widespread application and development. By analyzing the causes and treatment of the zombie process, function waitpid ( ) is used to avoid the zombie process. Furthermore, corresponding strategy is formulated by analyzing the quit status information and it is made sure that meteorological data exchange accurately, timely and efficiently in BMTS. On the other hand, by comparing many interprocess communication technologies and combining domestic communications features and the actual business, message queue is adopted. Now the processing time of newly data on BMTS decreases to 43%. After solving the problems above, multi-process technology is applied on BMTS, by which the transmission efficiency of domestic meteorological data is improved. This software has been running reliably and stably in the system since 2005 and real-time exchanging and sharing of the nationwide newly meteorological data are ensured.
