Arc light data uploading method based on fiber double-loop network

Abstract

The invention discloses an arc light data uploading method based on a fiber double-loop network. The method comprises the following steps of (1) making a plurality of arc light expanders and two arc light protecting devices inside an arc light protecting system connected through fibers and interconnected through an HSR protocol to form a fiber double-loop network structure; (2) uploading locally sampled arc light data through each arc light expander with a 0.5ms interval to achieve arc light data sharing between the two arc light protecting devices, wherein, the arc light data are HSR protocol messages; (3) transmitting and receiving arc light data by each node through the other fiber loop network when one fiber loop network is faulty. The arc light data uploading method based on the fiber double-loop network achieves high-speed and reliable communication among the arc light expanders and the arc light protecting devices and solves various problems in a conventional arc light protecting system. The method which further improves the arc light protecting motion speed and reliability has a great application prospect.

Description

technical field [0001] The invention relates to the technical field of arc light protection systems, in particular to a method for sending arc light data based on an optical fiber double ring network. Background technique [0002] The arc light data of the arc light probe needs to be sent to the arc light protection device quickly and reliably. The speed of sending the arc light data must be high to ensure that the arc light protection device can quickly cut off the arc. Moreover, the transmission channel of the arc light data must have a high speed. The reliability of the arc protection device is avoided due to the failure of the communication line. [0003] At present, the domestic arc protection system adopts the method that the arc extender sends data to the arc protection device through the serial port. However, because the serial port of the arc protection device is limited, in order to access the number of arc probes, it is necessary to use the arc extender. Step-by-...
