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.

Abstract: An upper limb rehabilitation training system integrating multi-source stimulation is provided and includes an upper limb rehabilitation body provided with first through fourth rigid rings, the first through fourth rigid rings are fixed with first rope knots, second rope knots, third rope knots and fourth rope knots respectively. The upper limb rehabilitation training system integrating multi-source stimulation simulates working principles of muscle more authentically by using linear drive method, and complies with laws of human kinematics. The linear drive method reduces many complex mechanical structures, and makes process of force transmission very easy. The upper limb rehabilitation training system integrating multi-source stimulation reduces weight of a rehabilitative robot, improves wearing comfort, and provides a basic guarantee for patients to devote themselves to rehabilitation training.
