Abstract This paper deals with automatic generation of motion of a point under both geometric and non-geometric constraints. Optimal point paths are generated which are not only free of collisions with polygonal obstacles representing geometric constraints but also conform to non-geometric constraints such as speed of the motion, a maximum allowable change in the velocity vector and a minimum clearance from the obstacle boundaries. The concept of passage networks and conforming paths on the network are introduced. These are used to provide a new representation of the free space as well as a motion generation algorithm with a computational time complexity of only O(n3.log(n)), where n designates the total number of obstacle vertices. The algorithm finds the shortest or fastest (curved) path that also conforms with preset constraints on the motion of the point. The point paths generated are proved to be optimal while conforming to the constraints.

The power structure of main electrical wiring diagram outgoing line in Zhongmu 500kV substation is analyzed firstly, and then the substation communication system based on Bluetooth technology was put forward in this paper. The power and critical loads are important, the connection lines and the connection modes in the substation are very complicated. Bluetooth technology can replace wired cable connection with the wireless interface in the short distance, prevent from complicated line in industry. This paper analyzes and designs model of the network in the substation, enhancing the automatic and intelligence level. Substation monitoring system was composed of meters, relays and other communication devices with Bluetooth components. The structure of the system can be divided into three layers, the bottom is monitor, the terminal in high-voltage chamber is the middle layer, the central processor in Control Building is the most top, bottom communicate with middle layer by Bluetooth technology.The system architecture, software, hardware and the necessary factions of this system are introduced.
