Objective: To observe the effect of upper limb rehabilitation robot combined with upper limb rehabilitation training on motor function of upper extremity of hemiplegic patients in recovery stage of stroke.MethodsA total of 40 hemiplegic patients in recovery stage of stroke who were treated in the Zhujiang Hospital of Southern Medical University from October 2018 to January 2020, which were randomly divided into the control group and the observation group according to the random number table method, with 20 cases in each group. Both groups received basic medication and conventional rehabilitation therapy (including good limb position, active and passive joint movement, sitting and standing balance training, walking function training, assistive device use training, speech and swallowing therapy, conventional physical therapy, etc.). The control group received upper limb rehabilitation training on the basis of basic medication and conventional rehabilitation therapy, 60 minutes a time, once a day, seven days a week, continuous treatment for two weeks. The observation group received upper limb rehabilitation robot training on the basis of the control group, upper limb rehabilitation training for 30 minutes a time, upper limb robot rehabilitation training for 30 minutes a time, once a day, seven days a week, continuous treatment for two weeks. Before and after treatment, the Fugl-Meyer assessment-upper limb (FMA-UL) was used to evaluate the motor function of upper extremity, including the FMA shoulder and elbow (FMA-SE) score and the FMA wrist and hand (FMA-WH) score; the Barthel index (BI) was used to evaluate activities of daily living; the root mean square (RMS) and integral electromyography (iEMG) values of the biceps, triceps, deltoid of anterior and middle fiber of the affected upper limbs of the subjects during maximal isometric contraction were measured by surface electromyography to assess muscle activation and synchronization of motor recruitment of the upper limbs.ResultsA total of 38 hemiplegia patients in the recovery stage of stroke completed the whole course of treatment. Compared with before treatment, FMA-UL score, FMA-SE score, FMA-WH score, BI score, RMS values of biceps, triceps, deltoid of anterior and middle fiber, and iEMG values of the both groups after treatment were significantly higher, with statistically significant differences (PP

[Introduction] Generally, there are various energy forms in industrial park, such as cold, heat, electricity, gas and so on. In most instances, the coupling of various types of energy isn't strong and mutual coordinated conversion isn't realized efficiently, resulting in widespread energy waste and shortage in industrial park. Therefore, it is necessary to carry out the research on comprehensive energy management system of industrial park, so as to accomplish the operation optimization and control of the energy in industrial park. [Method] This paper described the system architecture, key application of the integrated energy management system based on the characteristics of the energy in industrial park. [Result] The designed integrated energy management system can provide technology support for coordinated and optimized operation of various energy sources in industrial park. [Conclusion] Integrated energy management system of industrial park can integrate the controllable resources of various energy forms and improve energy utilization efficiency and achieve the sustainable development of energy in industrial park.

[Introduction] Base on the wind power, photovoltaic, small hydropower, coal-bed methane power generation and other intermittent energy with volatility and randomness, large-scale intermittent energy will bring great influence on the power grid′s safe and stable operation and control after connected to the power grid, and the traditional power grid operation control system can′t completely adapt to the operation control for large-scale intermittent power. In order to realize the operation control of the intermittent energy, it is necessary to study the intermittent energy control system. [Method] In the paper, designed the system architecture, key application technology of multi-energy joint operation control system base on the characteristics of intermittent power, provided technology support for the control of the intermittent power. [Result] Multi-energy joint operation control system has realized the intermittent power to participate in power grid operation control, and improved the ability to deal with the intermittent power fluctuation. [Conclusion] The system has been applied in Guizhou power grid, and has been proved the feasibility of control of the intermittent power.
