With the vigorous promotion of national and local policies, the number of electric vehicles has been greatly increased, and orderly charging has gradually become an effective means to relieve the pressure of charging and capacity. In order to enhance the participation of charging load aggregators and charging users, improve the effectiveness of orderly charging, and realize the win-win situation between the aggregators and users, in this paper, firstly, the analysis of charging station benefit model is carried out from two aspects of charging station operation cost and compensation price, and then the user charging supplement mechanism based on response mechanism is studied and finally through simulation examples, different scenarios of charging equipment utilization are set, and the benefits of charging load aggregators and charging users are analysed, which provides suggestions for charging load aggregators to choose appropriate user compensation scheme under orderly charging mode.

For the current lack of convenient, reliable and safe lifting of the fire escape equipment, design a device along the rope, using functions with self-locking worm gear structure. Then assess the strength of the contact state and reliability of the structure, use ANSYS to analysis the contact stress and dynamic characteristics. Finally, improve the winch device design to increase the safety factor. The check calculation and experiments showed that the device can be safely hoisting the target.

This paper introduces a novel auto-control mode of the ship loader. Presents a method of bulk ship loader’s remote-operation that controlled by the port’s central-monitor. Meanwhile, Design a load-inspect system for the auto-control loader by the technology of sensor inspection and image manipulation.This control mode is worth to continue to explore.

According to medical and physiology study of human health, combined with the authoritative media chronicle , it can be sure that the crawl is a very comprehensive range of whole body movement.This design is based on ergo- new crawl exercise machine. it uses software such as Matlab and ansys ug into Structure design and load analysis , the check and Practical application,it is proved to satisfy a 150 kilograms user’s need. it provides the user with a variety of modes, such as the exercise forwardly or exercise passively. At the same time, it is equipped with the safety precautions and voice control and other perfect facilities.The crawl exercise machine can be used extensively in the family, the hospital, the fitness club, etc.

The autonomous navigation process of a mobile service robot is usually in uncertain environment. The information only given by sensors has been unable to meet the demand of the modern mobile robots, so multi-sensor data fusion has been widely used in the field of robots. The platform of this project is the achievement of the important 863 Program national research project-a prototype nursing robot. The aim is to study a mobile service robot’s multi-sensor information fusion, path planning and movement control method. It can provide a basis and practical use’s reference for the study of an indoor robot’s localization.
