摘要:

针对现有太阳能照明系统普遍存在的效率低、寿命短、运行不稳定等问题,设计了一种具有无线联网功能的新型ZigBee太阳能路灯控制器。该控制器包括充电控制模块、数据采集模块、LED灯驱动模块、无线通信模块和电源管理模块。对蓄电池充电状态实时监测并准确切换充电模式以提高充电效率,采用扰动观察法实现太阳能板最大功率点跟踪,采用LED恒流控制措施达到节能效果。联合ZigBee、GPRS、Internet的组网策略实现太阳能路灯自组建网络和远程智能监控。试验结果表明,应用该控制器的太阳能照明监控系统效率高、运行稳定,真正实现了太阳能LED照明的智能化管理,具有广阔的应用前景。

There are some problems in photovoltaic lighting systems, such as low efficiency, instabilities, short battery life, etc. To solve these problems, a novel type of ZigBee solar street lamp controller with wireless networking function is designed in this paper. The controller consists of five main parts: charging circuit, sensor module, LED driving circuit, wireless communication module and power management module. The real-time working state of battery is monitored and switched accurately to improve the efficiency of charging. Perturbation and Observation Method is used to realize maximum power point tracking (MPPT) of the solar panel. A constant-current control is taken to achieve energy-saving. The networking strategy combined ZigBee, GPRS, Internet is applied, so the solar lamps can establish network by themselves and be monitored and controlled by remote center. By testing the experimental result, it is proven that the solar LED lamps with this new controller can operate efficiently, stably, and be managed intelligently. It has a broad application prospect.
