    Periodic low-power communication technology scheme for large-scale transmission line condition monitoring sensor network by Yabo ZHAN, Qian XU, Jun LI, Zhen ZONG

    Published 2023-02-01
    “…In order to realize the purpose of low energy consumption, long service life and green development of transmission line monitoring, a periodic low-power communication technology scheme of large-scale transmission line condition monitoring sensor network was proposed.According to the networking characteristics of sensor networks in large-scale transmission line condition monitoring networks and the characteristics of node operation condition conversion, sleep timers were set to make the communication nodes of sensor networks switch between initialization, sleep and activation states in a periodic operation mode.The communication nodes entered the sleep state when there was no transmission demand for transmission line condition monitoring data, so as to save communication energy consumption.Sink nodes in sensor networks used gradients to create uplink routes and source routes to create downlink routes.Based on the number of hops and residual energy, sink nodes transmitted uplink and downlink routing data packets, to reduce node energy consumption and prolong communication running time.Experiments show that after the large-scale transmission line condition monitoring sensor network applies the technical solution, the communication energy consumption is significantly reduced, the running time is significantly prolonged, and the data transmission performance of the monitoring sensor network is not affected, and the service life of the monitoring sensor network is prolonged.…”

    Research on multi-stream variable resolution compression and transmission technology based on scene elements in Internet of things environment by Shangwu XIAO, Ruimin HU, Yu CHEN, Jing XIAO

    Published 2018-12-01
    “…In response to the demand of wide coverage and massive access,low bandwidth and low power consumption is an important research direction to solve this problem.In smart cities,security monitoring and other application areas,video surveillance based on the region of interest of the face are particularly important.It is a feasible direction to realize the extraction of scene elements,transmission of key information with very low bandwidth and the application of video technology in the Internet of things environment through the strategy of multi-stream differential coding.By designing a face-oriented variable resolution hybrid coding algorithm,the bandwidth could be saved and the power consumption could be reduced greatly,the access requirements of narrowband Internet of things could be met.Through the face detection algorithm based on the deep learning Caffe framework,the face region of interest was acquired in key frames,and the face image was encoded with high resolution.By designing the code rate adaptive allocation algorithm,the bandwidth was utilized rationally,and the encoded face information and the full background content were distinguished.The encoded mixed code stream information was transmitted through the narrowband; the key frame-based face enhancement decoding algorithm was adopted at the receiving end to obtain a partial HD high-definition monitoring picture.Experiments show that when the video encoded by the proposed method is transmitted in a narrow band whose transmission rate is 120~160 kbit/s,the face image can maintain the same definition as the original HD monitoring acquisition end,which has strong practicability.…”
