Problems solved by technology

In response to this phenomenon, the current conventional solution is to add electromagnetic compatibility devices to the hardware circuit to reduce the generation of electromagnetic interference signals. However, due to the complex and changeable installation environment of the online monitoring device, the anti-interference devices cannot completely eliminate interference, and there are still a large number of Bit error problem, in addition, too many anti-electromagnetic interference devices also require high installation and maintenance costs
[0007] In order to overcome the failure of online monitoring information collection of transmission lines caused by electromagnetic interference, an improved online monitoring information collection method for transmission lines is very much needed

Abstract

The embodiment of the present invention provides a transmission line online monitoring information collection method, device and system, the method includes: sending a collection command; receiving one or more data packets returned by the sensor; if the data packet contains a data packet header, the Delete the characters before the data packet header, if the data packet contains the data packet tail, delete the characters after the data packet tail; judge whether the remaining characters in each data packet are preset valid characters, if not, delete; combine the remaining characters in all data packets to obtain a reassembled data packet; verify the reassembled data packet according to the preset verification rules; if the verification fails, discard the reassembled data packet and resend the collection command. The invention effectively solves the error code problem of the data packet caused by electromagnetic interference and the like, improves the reliability of the on-line monitoring system of the transmission line, and has the advantages of low cost, easy maintenance and the like.

Description

technical field [0001] Embodiments of the present invention relate to the field of electric power technology, and more specifically, embodiments of the present invention relate to a method, device and system for collecting online monitoring information of transmission lines.
