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

Embodiments of the invention provide a power transmission line online monitoring information acquisition method, device and system. The method includes the steps of sending an acquisition instruction; receiving one or more data packets returned by a sensor; if each data packet contains a data packet header, deleting characters located before the data packet header, and if each data packet contains a data packet tail, deleting characters located after the data packet tail; determining whether the remaining characters in each data packet are preset valid characters, and if not, deleting the characters; assembling the remaining characters in all the data packets to obtain a reassembled data packet; verifying the reassembled data packet according to a preset verification rule; and if the verification fails, discarding the reassembled data packet and resending an acquisition instruction. According to the invention, the problem of data packet bit errors caused by electromagnetic interference and the like is effectively solved, the reliability of the power transmission line online monitoring system is improved, and the advantages of low cost, good maintenance and the like are gained.
Description
Technical field [0001] The embodiments of the present invention relate to the field of electric power technology, and more specifically, the embodiments of the present invention relate to a method, device, and system for collecting online monitoring information of a power transmission line. Background technique [0002] This section is intended to provide background or context for the embodiments of the invention stated in the claims. The description here is not recognized as prior art just because it is included in this section.
