The invention discloses a railway electronic speed limit indicator and an application method, and the railway electronic speed limit indicator comprises a ground speed limit board which is arranged in a railway speed limit area and is used for displaying speed limit information; the vehicle-mounted receiver is arranged on the locomotive and is in two-way wireless communication connection with the ground speed limit board; and the group operation protector is arranged in a railway staff operation area and is in two-way wireless communication connection with the ground speed limit board and the vehicle-mounted receiver respectively. The ZigBee wireless communication technology is used for enabling every two of the ground speed limit board, the vehicle-mounted receiver and the group operation protector to be in two-way wireless communication connection, and mutual information transmission is facilitated. In addition, a Beidou signal receiving module and an AFLT positioning module are embedded in the ground speed limit board, the vehicle-mounted receiver and the group operation protector respectively, so that the position information of the ground speed limit board, the vehicle-mounted receiver and the group operation protector can be accurately acquired. According to the invention, not only is the driving instruction transmitted to the locomotive on the railway realized, but also the accurate coming train information forecast can be provided for the railway field operation personnel.
本发明公开了一种铁路电子限速指示牌及应用方法,包括地面限速牌,设在铁路限速区域,用以显示限速信息;车载接收器,设在机车上,与地面限速牌双向无线通信连接;群体作业防护器,设在铁路职工作业区,与地面限速牌、车载接收器分别双向无线通信连接。本发明利用ZigBee无线通信技术使地面限速牌、车载接收器、群体作业防护器两两之间双向无线通信连接,便于相互进行信息传递。此外,地面限速牌、车载接收器、群体作业防护器中分别嵌入有北斗信号接受模块以及AFLT的定位模块,便于精准的获取地面限速牌、车载接收器、群体作业防护器的位置信息。本发明不仅实现了对铁路上的机车传送行车指令,而且可向铁路现场作业人员提供精准的来车信息预告。
