针对目前变电站保护硬压板巡检多由人工进行读取和核对操作,费时费力且易出错,难以满足变电站二次设备智能化的要求的问题,研究了基于YOLOv3算法的变电站保护硬压板检测与状态识别技术。首先,通过对变电站保护硬压板进行数据采集和标注,建立了一个包含大量样本的数据集。然后,使用YOLOv3算法进行目标检测,实现了对变电站保护硬压板的准确定位和识别。针对硬压板的不同状态,设计了相应的特征提取和分类模块,通过对检测到的硬压板进行状态识别,实现了对硬压板状态的准确判别。实验结果表明,该方法在变电站保护硬压板检测和状态识别方面具有较高的准确性,对压板作业操作票确认、压板状态校核等业务实现具有一定参考价值,可为变电站设备的状态监测和故障的智能诊断提供有效的技术支持。

Urban planning is a process of government as planner to purposefully manage and intervene in the urban development. In this paper,five major tasks for the construction of an international language environment in the core urban areas are proposed from the perspective of urban planning:to explore an effective working mechanism for the construction of the international language environment;to improve the ability of citizens in foreign language communication;to standardize public bilingual notices and signs marking system;to innovate the internationalized operational models of the key industries;to create a multi-functional foreign language consulting service system. Thereby,the objective to improve the international language environment and competitiveness of the urban areas can be accomplished.

We propose a Quantum private query(QPQ) protocol based on device-independent Quantum key distribution(QKD) by using Einstein-Podolsky-Rosen(EPR) pairs. We analyze coherent attacks by a third party in a weaker constraints(non-signaling condition) compared with the formalism of quantum physics. We deduce the relationship between the raw key bits of Alice and the third party’s attack factor. Compared with existing QPQ protocols, our protocol is secure even when the source and measuring equipment used to distribute oblivious secret key can not be trusted. Quantum register is not needed in our protocol.

This work presents two robust quantum secure communication schemes with authentication based on Einstein-Podolsky-Rosen(EPR) pairs, which can withstand collective noises. Two users previously share an identity string representing their identities. The identity string is encoded as decoherence-free states(termed logical qubits), respectively, over the two collective noisy channels, which are used as decoy photons. By using the decoy photons, both the authentication of two users and the detection of eavesdropping were implemented. The use of logical qubits not only guaranteed the high fidelity of exchanged secret message, but also prevented the eavesdroppers to eavesdrop beneath a mask of noise.
