    Abstract: A micro-power wireless access method and apparatus for the Internet of things for power transmission and transformation equipment involves a time synchronization process, a traffic channel access process, a control channel configuration information access process, and a control channel burst information access process. In the time synchronization process, an aggregation node determines a delay parameter and other parameters based on a timeslot in which traffic information randomly transmitted by a sensing terminal is located, and the sensing terminal adjusts transmission time of a corresponding frame based on the parameters. The traffic channel access process adopts a mode in which one-way reporting is mainly used, to minimize working time of a sensor. The present disclosure realizes limited two-way communication on a control channel, supports configuration of a sensor cycle, a threshold, and other parameters, and supports a retransmission mechanism on the control channel for important alarm information.

  • Patent number: 11408845
    Abstract: Disclosed a passive wireless sensor for detecting discrete droplets and bubbles. A first inductor channel and a second inductor channel are disposed opposite each other to form a capacitor channel, the first inductor channel is connected to the second inductor channel to form a resonant circuit. When a detection object passes through the detection channel, the permittivity between the first inductor channel and the second inductor channel changes and consequently a capacitance value of the capacitor channel changes, thus resulting in a change in resonant frequency of the resonant circuit. A readout device is used to read the resonant frequency of the resonant circuit and perform detection according to the resonant frequency to obtain information of a corresponding detection object.

  • Publication number: 20220245298
    Abstract: The disclosure discloses a dynamic stability analysis method and device for a linear time-periodic (LTP) system. The method includes the following steps. Calculate the Q matrix corresponding to the LTP system, and use the eigenvalue of Q matrix whose real part is positive as an instability eigenvalue. Each instability eigenvalue is subjected to the following steps. (S1) the state space model is transformed into the infinite-order harmonic state space (HSS) model, and the truncation order m of HSS model is initialized to 1. (S2) after m-th order truncation of the HSS model, its eigenvalue thereof is calculated. If the real part of the eigenvalue of HSS model is not the same as the real part of the instability eigenvalue, m is updated, and step (S2) is performed again; otherwise, modal participation factor analysis is performed to obtain the state variables that dominate the system instability.
