模块化PLC技术在港珠澳大桥交通工程中的应用

Application of Modular PLC Technology in Traffic Engineering of Hong Kong-Zhuhai-Macao Bridge

在具有较强腐蚀性的潮湿空气环境中,可编程逻辑控制器(PLC)以其可靠性高、抗干扰能力强的优点在隧道运营管理中得到了广泛应用。在港珠澳大桥交通工程的运营管理中,人们采用易于分割、组织和打包软件的模块化程序,有效解决了庞大复杂系统的模块化管理问题,既满足了正常运营管理功能的需要,又为未来港珠澳大桥交通管理系统的功能升级、系统功能扩展提供了接口资源。

In the humid air environment with strong corrosiveness,programmable logic controller(PLC)has been widely used in tunnel operation and management due to its high reliability and strong anti-interference ability.In the operation and management of the Hong Kong-Zhuhai-Macao Bridge traffic project,people adopt modular programs that are easy to divide,organize,and package software,which effectively solves the problem of modular management of huge and complex systems,it not only meets the needs of normal operation and management functions,but also provides interface resources for the functional upgrade and system function expansion of the future Hong Kong-ZhuhaiMacao Bridge traffic management system.
