High-pressure vacuum contactor is an important primary equipment for high-voltage power plant system in power plants. It has the advantages of low noise, long service life and frequent operation. It is mainly used for the control of high-voltage motors in factories. If the switch is repeatedly switched on and off, it will cause great impact force on the stator coil and rotor squirrel cage bar of the motor, and damage the insulation of the winding and cause overheating and fracture of the squirrel cage bar. At the same time, it may also cause bus grounding, damage or even explosion of the switch contacts. Therefore, it is necessary to analyze and discuss the fault causes of the anti-jump control loop of the high-voltage vacuum contactor of the power plant, and seek to solve the "anti-jump" scheme. The control loop is optimized by analysis to solve the fault, and technical support is also provided for the anti-jump circuit of the 6kV vacuum switch and the FC switch.
高压真空接触器是电厂高压电厂系统的重要一次设备。它具有噪音低,使用寿命长,操作频繁等优点。主要用于工厂高压电机的控制。如果反复开断开关,会对电机的定子线圈和转子鼠笼棒产生很大的冲击力,损坏绕组的绝缘,造成鼠笼棒过热断裂。同时,还可能造成母线接地,开关触点损坏甚至爆炸。因此,有必要对电厂高压真空接触器防跳控制回路故障原因进行分析探讨,寻求解决“防跳”方案。通过分析优化控制回路,解决故障,并对6kV真空开关和光纤开关的防跳电路提供技术支持。

Research on Physical Layer Security of Cooperative Networks Based on Swipt 基于swift的协同网络物理层安全研究
Pub Date : 2019-08-01 DOI: 10.1109/ICSGEA.2019.00135
Hao Hao, Xin Wang Ying Li
In Cooperative Networks based on simultaneous wireless information and power transfer (SWIPT), relay nodes collect the energy of radio signals received from source node and transmit the information of source nodes to destination nodes, which not only prolongs the service life of energy-constrained nodes, but also improves the ability of long-distance transmission of information. Due to the openness of energy harvesting, there may be eavesdropping users with malicious decoding. In order to study the security performance of the Cooperative Networks based on SWIPT, this paper mainly studies the physical layer security performance of this network, derives and simulates the expression of system security outage probability and throughput. The simulation results show that the system security performance is mainly influenced by time allocation parameter of SWIPT and decreases with the increase of target rate.
在基于同步无线信息与功率传输(SWIPT)的协同网络中,中继节点收集源节点接收到的无线电信号的能量,将源节点的信息传递给目的节点,既延长了能量受限节点的使用寿命,又提高了信息的远距离传输能力。由于能量采集的开放性,可能存在恶意解码的窃听用户。为了研究基于SWIPT的协作网络的安全性能,本文主要研究了该网络的物理层安全性能,推导并模拟了系统安全中断概率和吞吐量的表达式。仿真结果表明,系统的安全性能主要受SWIPT时间分配参数的影响,并随着目标速率的增加而降低。

A New End-to-End Secondary Network for High-Efficient Vehicles and License Plates Detection 一种新的端到端辅助网络,用于高效车辆和车牌检测

Up to now, a number of existing methods have worked fairly well in the field of vehicle and license plate detection. However, those methods are still not sufficient enough for satisfying practical industrial demands in terms of efficiency and accuracy, exhibiting poor performances such as incomplete detection of license plated when multiple vehicles are contained in the target image, and poor vehicle recognition when illumination is inadequate at night. To solve these limitations, a novel end-to-end secondary detection network named ES-Yolov3-tiny is proposed in this paper. ES-Yolov3-tiny can improve detection efficiency and accuracy by virtue of the secondary detection technology, and detect multiple vehicles in the same target image with the help of the interested region extraction technology. Compared with other existing state-of-the-art methods, the experiments show that the proposed method has better accuracy and lower computational cost.
到目前为止,已有的一些方法已经在车辆和车牌检测领域取得了很好的效果。然而,这些方法在效率和精度上仍不足以满足实际工业需求,在目标图像中包含多辆车辆时,车牌检测不完全,在夜间光照不足时,车辆识别效果较差。为了解决这些限制,本文提出了一种新的端到端二次检测网络ES-Yolov3-tiny。ES-Yolov3-tiny利用二次检测技术提高检测效率和精度,利用感兴趣区域提取技术对同一目标图像中的多辆车辆进行检测。实验结果表明,该方法具有较高的精度和较低的计算成本。

A recommendation algorithm is put forward for the potential candidate recommendation technology in human resources. The dynamic decision diagram is combined in this method based on collaborative filtering technology and partition clustering technology. Firstly, the computational matrix that integrates the dynamic decision diagram recommendation algorithm is established so that the algorithm can recommend information in reference to the matrix. Secondly, the assignment range of the matrix is improved, so that the recommendation algorithm can integrate the evaluations of all users. Finally, the evaluation value and the update coefficient are added, which makes the dynamic update of the algorithm possible, thus recommending the most satisfactory information to the users. On this basis, an advanced recommendation algorithm based on partition clustering is proposed, which has further improved the precision and real-time performance of the algorithm. In addition, experiments are carried out to verify that the ultimate commendation algorithm based on partition clustering is the optimal recommendation algorithm for potential candidates in human resources, which can provide the most satisfactory information to users.

The fundamental problem of the emergency repair and construction is to evaluate the efficiency of the support plan of emergency supply for earthquake repair. This paper constructs reasonable evaluation model of each support plans' input and output based on DEA and gets the relative efficiency of each support plans to choose the rational plan. When fuzzy DEA can not evaluate the efficiency of support plans in the special case which is after the earthquake and the outputs are fuzzy data, it can get average efficiency by using Monte-Carlo method to simulate the outputs of each support plan and provide decision makers with scientific basis for choosing the rational support plan.

In order to avoid the flight dysfunctions caused by the failure and damage of the actuator, the sensor, and the structure of the unmanned aerial vehicle (UAV) for the UAV could return safely or continue to complete the missions, the adaptive control technology, the PID control technology, and other related technologies have been combined to study the fault tolerant control of UAV. At the same time, in order to ensure the speed and stability of the aircraft, a robust based multi-model adaptive control system is designed for the attitude control of the quadrotor UAV rotor aircraft; in addition, the effectiveness of the above method is verified through simulation experiments. The results have shown that if the flight control system can detect and identify the system faults in time and take certain fault tolerant controls, the survivability of the UAV would be greatly improved.
为了避免无人机的致动器、传感器和结构发生故障和损坏而导致飞行功能障碍,使无人机能够安全返回或继续完成任务,结合自适应控制技术、PID控制技术等相关技术对无人机的容错控制进行了研究。同时,为了保证飞行器的速度和稳定性,设计了基于鲁棒的多模型自适应四旋翼无人机旋翼机姿态控制系统;此外,通过仿真实验验证了上述方法的有效性。结果表明,如果飞行控制系统能够及时发现和识别系统故障,并采取一定的容错控制,将大大提高无人机的生存能力。
