【摘要】 针对目前园区路灯维修不及时与能耗问题,设计了一种基于物联网的园区智慧路灯系统。基于stc15w408as处理器设计传感器子节点,实现路灯光照度和环境光照度的数据采集,并利用人体红外传感器实时检测是否有人经过;采用低功耗SI4463无线模块实现子节点与协调器节点之间的通信,并利用TCP/IP技术实现了远程数据中心与ARM板的跨平台通信;在此基础上,设计了一种简单自组网路由算法实现子节点之间数据传输的最佳路由,并通过PC/手机用户对园区路灯远程实时监控,实现园区路灯节能和自动报修,有效地降低了能耗。测试结果表明,系统运行稳定,具有一定实用价值。更多还原

【Abstract】 By considering the problems of repairing and energy consumption,a smart streetlights system of park is designed based on internet of things. Sensor sub nodes are designed based on stc15w408 as processor to acquire the illuminance of the streetlights and the ambient illuminance. The infrared sensor of human body is used to detect whether someone is passing by in real time.The communication between sub nodes and coordinator nodes is implemented by low power SI4463 wireless module,and ARM board communicates with remote data center by TCP/IP technology. A simple ad hoc network routing algorithm is applied to find the optimal routing of data transmission. Through remotely real-time monitoring of streetlights by PC/Phone users,saved energy,automatic repair,consumption is decreased. The test results show that the system is stable and has practical value.更多还原
