双模货物列尾系统场强覆盖电平计算方法

Field Strength Coverage Level Calculation Method of Dual-mode EOT System of Freight Train

货物列车尾部安全防护系统是用于货物列车取消守车后,在尾部无人职守情况下,为提高铁路运输的安全性而设置的专用运输安全装置,是重要的铁路行车设备。为此分别对双模列尾机车台和列尾主机所需的最小场强覆盖电平进行了计算,并将计算数值等效于同等情况下机车电台(CIR)天线处输入端的场强覆盖电平,以便统一确定普速铁路列车的GSM-R网络场强覆盖要求。

The End of Train （EOT） Device is special train operation device designed for improving the safety of railway transportation in the case of unmanned duty in the end of a train. The minimum field strength coverage levels are calculated respectively for both the dual mode EOT cabinet and the EOT mainframe and the data calculated above is also assumed as a equivalent to the field strength coverage level at the point where the antenna of the CIR radio set so as to determine the requirement of field strength coverage of the GSM-R network for ordinary-speed trains.
