港口海关电子闸集成系统的设计与开发

Research and Development of Integrated System for Automatic Toll-gates in Container Terminals

针对某大型港口海关对通关效率和可靠性的要求,通过分析系统结构、功能,提出了采用分布式结构的大型港口海关电子闸集成系统。分析了系统在准确性、可靠性、稳定性以及抗干扰能力等方面的要求,对系统的部分通讯采用冗余通讯方式,对系统部分设备进行冗余控制。研究了工业以太网及现场总线等技术在系统中的合理运用。系统通过在某港口一个多月的运行测试,证明其稳定性等指标都实现了预期目标。

Introducing an efficient and reliable system which is designed for a large container terminal via analyzing the construction and function of the system. Analyzing the requirements of precision,reliability,stability and anti-jam ability of system,employ redundancy in the system communication and redundant control in part of system. Study the applications of technologies,such as industrial Ethernet and Field Bus,in the system. And the test results show that the system is efficient.
