An efficient algorithm for condition monitoring of rotating machines is proposed in this paper. Condition indicators are derived from sound signals, and used to arrive at a decision about the performance state of the machine. Sound signals are recorded by microphones and processed using time-frequency domain analysis. In this study, number of statistical features; such as mean, standard deviation, skewness, and kurtosis are considered. These statistical features were proven to be effective and simple to interpret. Healthy, about to be faulty, and faulty performance states of the machine are considered, and audio signals are recorded for each state. The five main steps comprising the implemented approach are data acquisition, preprocessing, feature extraction, time and frequency domain analysis, and the decision making. Based on the adopted statistical measures, the experimental results indicate that an excellent recognition of machine performance states is obtained, leading to an efficient fault detection and diagnosis.

Monitoring bad road surface condition, such as break, potholes, obstacles, is helpful to prevent accidents in the case of cycling. In this paper, we consider to use low-cost ultrasonic distance sensor for monitoring road surface condition. We design and implement a monitoring system using an off-the-shelf node with a low-cost ultrasonic distance sensor. In the system, ultrasonic signal is periodically emitted to measure the distance from the system to the road so that the road surface condition can be estimated. To limit the sensing region, the ultrasonic distance sensor is covered by a plastic shield plate. Through experimental evaluations, we show that the monitoring system can detect the 360 cm away obstacle on road in the front area of bicycle. In addition, we show that the system also can detect a hole in the front area of bicycle. Keywords-bicycle; ultrasonic distance sensor; road surface condition monitoring; obstacle; hole; Arduino
监测恶劣的路面状况,如裂缝、坑洼、障碍物,有助于防止骑自行车时发生事故。在本文中,我们考虑使用低成本的超声波距离传感器来监测路面状况。我们设计并实现了一个监测系统,使用一个现成的节点与低成本的超声波距离传感器。在该系统中,周期性地发射超声波信号来测量系统到道路的距离,从而可以估计路面状况。为了限制传感区域,超声波距离传感器被塑料屏蔽板覆盖。通过实验评估,表明该监控系统可以检测到自行车前方360 cm外的道路障碍物。此外,我们还证明了该系统还可以检测到自行车前部的一个洞。Keywords-bicycle;超声波测距传感器;路面状况监测;障碍;孔;Arduino

Dynamic Acceleration Coefficient of Particle Swarm Optimization in Robotics Motion Coordination 机器人运动协调中的粒子群动态加速度系数优化
Pub Date : 2020-12-30 DOI: 10.5013/ijssst.a.21.03.06

This paper focuses on improving an optimization process for swarm robots using Particle Swarm Optimization (PSO) by altering the acceleration coefficient from static to dynamic. In swarm robotic, motion coordination addresses the issue of avoiding a group of robots interfere with each other in a limited workspace, while achieving the global motion objective. PSO is commonly suggested in the literature to optimize path trajectory in robotic field. However, the typical PSO tends to be trapped in local optima. Therefore, a dynamic acceleration coefficient is proposed to optimize the cognitive and social coefficients of PSO in order to improve its exploration ability in seeking the global optimum solution. With this novel feature, PSO becomes less dependent on the chain of its past experience that it had explored in a certain region within the solution space. The effectiveness of the proposed method is tested on a simulated swarm robotic platform. Results show the proposed PSO with Dynamic Coefficient (DCPSO) is 1.09 seconds and 3.58 seconds faster than the typical PSO under dynamic and extreme conditions respectively.
本文研究了利用粒子群算法(Particle swarm optimization, PSO)改进群体机器人的优化过程,将加速度系数由静态改变为动态。在群体机器人中,运动协调解决了在有限的工作空间内避免一组机器人相互干扰,同时实现全局运动目标的问题。粒子群算法是机器人领域中常用的路径轨迹优化算法。然而,典型的粒子群算法往往陷入局部最优。为此,提出了一种动态加速度系数来优化粒子群的认知系数和社会系数,以提高粒子群寻求全局最优解的探索能力。有了这个新特性,粒子群算法就不那么依赖于它过去在解决方案空间的某个区域探索的经验链了。在仿真蜂群机器人平台上验证了该方法的有效性。结果表明,在动态和极端条件下,该动态系数粒子群比典型粒子群分别快1.09秒和3.58秒。
