Embodiment 1

[0039]figure 1 It is a flow chart of an optical switch-based signal transmission method provided by Embodiment 1 of the present invention. This embodiment is applicable to a signal transmission network with multiple connected nodes, and each node is connected to an optical switch. In some cases, the method can be performed by a signal transmission device based on an optical switch, which can be implemented by software and / or hardware, and can be configured in a node of a signal transmission network. The method specifically includes the following steps:

[0040] S101. Send a first enabling signal to the current optical switch, so as to drive the current optical switch to establish a first transmission link.

[0041] In a signal transmission network, a node generally refers to a communication endpoint or a terminal device. A node in a network is an active electronic device connected to the network, capable of sending, receiving or forwarding information through a communication ch...

Abstract

The invention discloses a signal transmission method and device based on an optical switch, equipment and a storage medium. The method comprises the following steps: sending a first enable signal to the current optical switch, driving the current optical switch to establish a first transmission link, wherein the first transmission link indicates that the current optical switch receives a first signal transmitted by the previous optical switch, transmits the first signal to the current node, receives a second signal transmitted by the current node and sends the second signal to the next opticalswitch, and the second signal comprises the first signal and a signal generated by the current node; detecting the working state of the current node; and if the working state is an abnormal state, sending a second enable signal to the current optical switch so as to drive the optical switch to be switched from the first transmission link to the second transmission link. The signal transmission link is divided into two links, when a fault node occurs, only the fault node is discarded in the whole signal transmission network, it is ensured that other nodes can still work normally, the fault node is convenient to locate, the fault rate is reduced, and operation and maintenance of the network are convenient.

Description

technical field [0001] Embodiments of the present invention relate to signal transmission technology, and in particular to a signal transmission method, device, equipment and storage medium based on an optical switch. Background technique [0002] With the rapid development of smart highways, the amount of signals in the expressway network has increased significantly, and the integrity of signal transmission has become more and more important. [0003] The smart expressway mainly adopts a series connection to build a signal transmission network. When a node in the signal transmission network fails, the faulty node will be discarded, resulting in the loss of all signals of the node. The nodes are connected in series, and the subsequent nodes connected in series with the faulty node can no longer receive the signals in the previous signal transmission network, resulting in the interruption of the entire signal transmission link, and the signals generated by the subsequent node...
