目前,我国高速公路机电工程的大部分设备,是由工控机加各种接口板卡组成的。通过多年的使用、发展、换代,在性能指标等方面有了很大的提升,但这种系统设备还存在很多问题;给高速公路的建设和运营及维护管理发展带来了一系列的问题;如接口资源和可扩展性问题,直接影响着系统的可持续性和升级换代;特别是设备功耗问题,常常因设备功耗问题使系统不能正常工作,严重制约了高速交通的发
At present, most of the equipment of China’s expressway electromechanical engineering is composed of IPC and various interface boards. Through many years’ use, development and replacement, the performance has been greatly improved. However, there are still many problems with this kind of system equipment; a series of problems have been brought to the construction, operation, maintenance and management of the expressway; Such as interface resources and scalability issues, directly affect the sustainability of the system and upgrading; especially equipment power consumption, often because of equipment power consumption so that the system can not work properly, seriously hampered the development of high-speed traffic
