Design and Implementation of Intelligent Monitoring System for Street LampPoles Under the Background of Smart City Construction

为提高城市路灯光照质量,实现对大规模路灯的智能化、高效化管理,基于窄带物联网(NB-IoT)技术构建城市路灯灯杆智能化监控系统。该系统由感知层、传输层、平台层及应用层组成,通信模块选用BC20通信芯片,主控制选用STM32L151RCT6型处理器,达到节能降耗的目的。平台层选用移动One NET平台,应用层基于B/S架构,实现各层之间的交互连接与共享。测试表明,系统的平均定位速度达到0.1 m/s,定位精度可达5 m,当采用双控模式时,系统平均功率仅0.2 W,数据传输成功率>97%,具有低功耗的性能、良好的定位性能及数据传输稳定性能。

In order to improve the lighting quality of urban street lamps,and realize the intelligent and efficient management of large-scale street lamps,an intelligent monitoring system for urban street lamp poles is built based on the narrowband Internet of things(NB-IoT)technology.The system is composed of perception,transmission,platform and application layer.BC20 communication chip is selected as the communication module,and STM32L151RCT6 processor is selected as the main control,so as to achieve the goal of energy saving and consumption reduction.The mobile One NET platform is adopted at platform layer,and the application layer is based on the B/S architecture,so as to realize the interactive connection and sharing between all layers.Through the test of the system,the results show that the average positioning speed of the system can reach 0.1 m/s,and the positioning accuracy can reach 5 m.When the dual control mode is adopted,the average power of the system is only 0.2 W,and the success rate of data transmission is>97%.The system not only has the performance of low power consumption,but also has good positioning performance and data transmission stability.
