近年来中国铁路随着高铁的广泛覆盖,建设地域、地貌发生改变,方案标准发生变化,铁路安全运行要求的提高,促使通信系统朝着更复杂,通信业务朝着更全面的方向发展。而这些变化都将要求,通信工程概算编制必须采用更加多样、更加丰富的指标,来更加精准、更加有效地控制费用。这里,介绍一种采用“通信节点”和“通信系统”相结合的方法,划分通信概预算编制段落。 In recent years, with the extensive coverage of high-speed railways, the construction area and landforms of China’s railways have changed, the program standards have changed, and the requirements for the safe operation of the railway have been heightened. As a result, the communications system has been moving toward more complex communications services in a more comprehensive direction. All of these changes will require that the compilation of communications budget estimates must adopt more varied and rich indicators to control costs more accurately and effectively. Here, a method of combining “communication node” and “communication system” is introduced to divide the budgeting section of communication budget.
