    Abstract
    Substation as a power facility, the surrounding environment may have a variety of complex factors, such as strong electromagnetic field, strong electromagnetic interference, noise, dust and so on. These environmental factors may interfere with the positioning equipment and measuring instruments, affecting the accuracy of the measurement. Therefore, this paper proposes a high-precision positioning algorithm for substation live construction based on Beidou high-precision differential positioning. Neural network is introduced to monitor the abnormal position of substation voltage. Based on this, the Beidou high-precision differential positioning technology is used to realize the high-precision location of substation construction signal. The experimental results show that: For single electromagnetic interference and multi-electromagnetic interference, the research algorithm can realize the high-precision location of live construction position of substation, and the error is always less than 2m.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
