Authors: Fan Shi Ping , Wen Yong Jiang , Zhou Lin
Published: September 2013

There are some common problems, such as low sampling efficiency and large amount of calculation, in mobile localization algorithm based on Monte Carlo localization (MCL) in wireless sensor networks. To improve these issues, an enhanced MCL algorithm is proposed. The algorithm uses the continuity of the nodes movement to predict the area where the unknown node may reach, constructs high posteriori density distribution area, adds the corresponding weights to the sample points which fall in different areas, and filters the sample points again by using the position relations between the unknown node and its one-hop neighbors which include anchor nodes and ordinary nodes. Simulation results show that the localization accuracy of the algorithm is superior to the traditional localization algorithm. Especially when the anchor node density is lower or the unknown nodes speed is higher, the algorithm has higher location accuracy.

Simulation of Street Light Pole Controller Routing with OMNeT++
Authors: Jing Chun Guo , Wang Jun Wei
Published: September 2013

In street lighting system, the light pole controllers were used to monitoring and control each street light. The controller nodes were installed at each lighting pole and make up a network with RTUs. In this paper, a randomly forwarding routing strategy was proposed based on the controller network features. The controller nodes were divided many clusters according to the substation power scope. In one cluster, the controller nodes topology is mainly star structure. When a controller node received a packet, it randomly delays a period of time and decides forwarding packet instead of immediately forwarding. The decision is based on the packet propagation direction and other nodes whether sending or not. The randomly forwarding routing protocol were simulated in OMNeT++ environment and compared with the flooding protocol. The results show that the delay of proposed protocol is lower than that of flooding. The proposed protocol also has some special features such as simple, not need to maintain net topology and complex path discovery algorithms.
Simple Ant Routing Algorithm for WSNs Used in Power Line Monitoring
Authors: Li Li Fen
Published: September 2013

The special class of wireless sensor networks for monitoring power transmission lines may extend for hundreds of miles in distances. The sensor nodes in this class of networks are deployed along narrowly elongated geographical areas and form a chain-type topology. Thus routing protocols in such environments must be kept as simple as possible. In this paper, we present the Simple Ant Routing Optimizing Algorithm (SAROA) to offer a low overhead solution in optimizing the routing process. Four improved strategies were used in our approach. During the route discovery we have used a new local search mechanism, in which each node broadcasts a control message (FANT) to its neighbors, but only one of them broadcast this message again. During the route maintenance phase, we only use data packets to refresh the paths of active sessions. Finally, the route repair phase is also enhanced, by using a deep search procedure as a way of restricting the number of nodes used to recover a route. A broadest search is only executed when the deeper one fails to succeed. The simulation results show that the enhance algorithm can effectively jump out of the local optimum and satisfy the tolerable delay in network-wide data collection.

The principle of gas path electrostatic circular sensor was discussed in this paper, in addition, a monitoring experiment with self-made circular sensor was carried out on turbojet engine, and electrostatic signals were collected successfully to verify the validity and feasibility of the sensor. According to the signals monitored over 131h, typical signals of 233-240 phases were analyzed. It was proved that the unusual particles were caused by carbon deposition from fuel spray nozzle. Therefore, under real-time monitoring of gas path changes with electrostatic circular sensor, early warning could be provided for initial fault condition as well as real-time reference for condition-based maintenance.

This paper discussed the advantages of genetic algorithm in the load distribution of the thermal power plant, and several other commonly used algorithms: equal incremental method, nonlinear programming method, particle swarm optimization for comparison and analysis. Compared with other methods, the results of use the genetic algorithms to calculate the load distribution between the thermal power plant units were both simple and accurate. So use the genetic algorithms to calculate the load distribution could optimizing the allocation of unit load, reduce coal consumption, improve the efficiency of the unit, responded to the call of the national energy saving.

With the development of Condition-Based Maintenance, there is an urgent need for failure dependence of redundant components in parallel system. In this paper, Markov maintenance cost decision analysis based on failure dependence of components was put forward, moreover, maintenance cost optimal model of parallel system with cost rate was established, meanwhile, the minimum cost rate as well as corresponding optimal detection interval was obtained. Finally, failure dependence and dependent failure rate to parallel system maintenance cost optimal model were studied and realized to prove this theory.

The spare part requirement forecast is the base of maintenance management. The exact requirement forecast an important approach to improve availability and safety of the equipments and reducing the life cycle cost of equipments. The spare part requirement are not exactly forecasted under the traditional renewal suppose, hence it easily cause waste of money and backlog of goods. To improve the ability of repairable system spare part supporting under the imperfect maintenance, this paper researches on the spare part requirement forecast for the repairable systems under imperfect maintenance, provides the spare part requirement forecast models based on quasi-renewal theory and calculates the lower and upper bounds of systems availability. Finally, an example reveals the efficiency and operability of the model.

Published: September 2013

In order to solve the problem of pitting corrosion discrimination of rolling element bearing on vibrating screen. We established the vibrating model of pitting corrosion of rolling element bearing inner and outer rings faults on vibrating screen based on rotating machinery rolling element bearings operating mechanism and Hertz contact theory. We simulate this model and analyze the results. The results show that, when the outer ring of the rolling element bearing of vibrating screen has multi-point pitting corrosion, there is an apparent modulation phenomenon at the response amplitude. When the inner ring of the rolling element bearing of vibrating screen has multi-point pitting corrosion, there is a slight modulation phenomenon at the response amplitude.

This paper developed a new type of hexapod robot using self-developed flexible space bending joints which can not only move from side to side or back and forth but also rotate. Then the principle of the movement and the gait of the hexapod robot were investigated, the kinematics model on translational displacement and velocity was followed. Furthermore, the test bench and pneumatic control system were set up, and the displacement, velocity and acceleration of the center of were acquired by high-speed camera shooting means. Finally, the stability of the gravity center and the control method of the hexapod robot were studied. The research of this paper provides a theoretical and practical basis for the application of bionic hexapod robot.
