地铁监测平台信息发布系统的设计与实现

Mornitoring the key devices in metro signal system can improve the operation efficiency and improve the overall service level of metro. Metro mornitoring platform is designed for detecting the abnormal state of devices and imforming the relevant staff to maintain the abnormal devices as soon as possible. The information publishing system as a part of the metro monitoring platform can publish the alarm message to the relevant staff timely and accurately after the discovery of abnormal state of devices. The information publishing system contains a series of functional modules which are low coupling. So that the information publishing system has good scalability and can be applied to many types of metro monitoring platform. The functions of the information publishing system is verified by observing the change of multi level front end pages after sending the alarm message and alarm recovery message to the metro monitoring platform.
