基于OLP和2M光接口的继电保护信号传输系统及方法
摘要：
本发明公开了一种基于OLP和2M光接口的继电保护信号传输系统及方法，该系统包括两个站点，两个站点的之间设置有SDH传输系统，两个站点之间通过所述SDH传输系统通信；每个站点内部设置有继电保护装置和OLP设备，所述OLP设备的输入端连接有两个2M光接口板，所述继电保护装置与OLP设备的输出端连接，OLP设备接收两个2M光接口板输出的继电保护信号，选择其中任意一路正常信号输出至继电保护装置和SDH传输系统。本发明利用OLP设备具有的双路切换功能，为继电保护业务提供了冗余的路径，有效解决了2M光接口板无保护的现状。
摘要（英）：

The invention discloses a relay protection signal transmission system and a relay protection signal transmission method based on an OLP and a 2M optical interface. The system comprises two stations. An SDH transmission system is arranged between the two stations. Each station is internally provided with a relay protection device and an OLP device, the input end of the OLP equipment is connected with two 2M optical interface boards, and the relay protection device is connected with the output end of the OLP equipment. The OLP equipment receives the relay protection signals output from the two 2M optical interface boards, and selects any one of the normal signals to output to the relay protection device and the SDH transmission system. The invention provides redundant paths for the relay protection service by utilizing the dual-channel switching function of the OLP device, and effectively solves the problem that the 2M optical interface board has no protection.
