通信工程文献翻译——摘要：本文提出了一个网络控制的LED路灯照明系统。由于他们的寿命更长，更高的发光效率和更高的显色指数，正在考虑将使用LED作为现代路灯照明系统的一种很有前途的解决方案。所提出的控制网络，在高峰负荷时间使街道照明系统的电源断开，在过载条件下自动减少其在分布式电源系统的影响。它还可以降低功率消费，降低管理成本和监督每个街道照明设备的状态信息。为了满足系统的要求，无线传感器网络受用IEEE802.15.4TM标准。它的网络层实现了使用地理路由策略，它提供了低开销和高可扩展性功能。然而，由于已知的现有技术的缺点，一种新的路由算法被提出。仿真结果表明，该算法导致了适用于稀疏的大型场景时路由性能显著改善，例如街道照明系统。已进行实地测试符合IEEE 802.15.4标准的无线控制单元。所获得的实验结果表明，所提出的控制网络能够满足要求的LED路灯照明系统。

1.引言

一个城市的路灯照明系统在其基础设施中起着重要作用。这是负责保证社会安全和在夜间生活，行车安全和市容市貌的。在开始的时候，手动执行控制的油灯。随着电灯的发明，根据光水平，路灯照明的控制开始采用自动光电手段。自电灯发明以来，光源和各自的控制装置正在不断发展。另一方面，光电一直采用的公共照明控制系统已经超过60年。

现代街道照明系统需要智能控制网络，以降低功耗，减少维护和管理成本，监视每个设备的信息状态（灯泡的状态，电压和电流测量等），并启用新的控制能力系统（如：调光）。

取决于城市的街道上的地理分布，街道照明系统采用了大量独立设备，然而，这些设备添加通信功能需要一个复杂的网络拓扑结构，及其互操作性，可扩展性，.......

Abstract—This paper proposes a control network for a LED street lighting system. The use of LEDs is being considered a promising solution to modern street lighting systems, due to their longer lifetime, higher luminous efficiency and higher CRI. The proposed control network enables disconnection of the street lighting system from the mains during peak load time,reducing its impact in the distributed power system automatically at overload conditions. It also allows to reduce the power consumption, decrease the management cost and monitor the status information of each street lighting unit. In order to meet the system requirements, a wireless sensor network based on IEEE 802.15.4TM standard is employed. Its network layer is implemented using geographic routing strategy, which provides low overhead and high scalability features. However, due to well known drawbacks of the existing techniques, a novel routing algorithm is proposed. Simulations show that this algorithm leads to a significant improvement of routing performance when applied to sparse large scale scenarios, which is the case of a street lighting system. Field tests have been performed on

IEEE 802.15.4-compliant wireless control units. The obtained experimental results show that the proposed control network is able to meet the requirements of a LED street lighting system.

I. INTRODUCTION

The street lighting system of a city plays an important role on its infrastructure. It is responsible of guaranteeing the society security and living during nighttime, traffic safety, and city appearance. In the beginning, the control of the oil lamps was performed manually. With the invention of the electric lamps, the control of the street lighting started to be carried on automatically, by means of photocells, according to the light level. Light sources and their respective control gears are being constantly developed since their invention. On the......
