Research Of Intelligent LED Landscape Lighting Embedded Monitoring System

In recent years,the huge advantages of LED light-emitting semiconductors in the field of lighting have been reflected.LED landscape lighting makes the dim night gorgeous,and has become a unique "business card" for city’s foreign exchange and cooperation.Because the working environment of LED landscape lighting equipment is mostly exposed outdoors,the actual work site still needs to rely on simple equipment and the experience of technicians to check the failure of LED landscape lighting equipment,but this situation is accompanied by huge risks.In view of this situation,based on modern fault diagnosis theory and technology,developing a smart LED landscape lighting monitoring system with high automatic integration and practical use is of great significance.The testing results indicates that the genetic algorithm improved particle swarm optimization wavelet neural network is better than standard wavelet neural network and standard particle swarm optimization wavelet neural network in the aspects of convergence speed and accuracy,which is based on the analysis of the structure and function of the neural network model in Matlab and the detection of the practical effect of the fault diagnosis process of an equipment.The design of intelligent LED landscape lighting embedded monitoring system mainly includes three parts:upper computer,lower computer and wireless communication.The upper computer is based on the ARM device of Super4412 model,which mainly implements system performance data processing,alarm threshold control,fault alarm location attribution and data storage and recall.The lower computer takes MSP430F149 single-chip microcomputer as the core to realize the data acquisition of the LED landscape lighting equipment by the sampling circuit.Wireless communication is the bonds of the upper and lower computer,using 433MHz wireless radio frequency module of HC-12 model to achieve short-range wireless communication.The upper computer works in the Android environment,and the design of system interface,fault diagnosis function,serial port communication and data storage are realized by Java and XML language.The lower computer adopts C language to realize the design of system interface and data collection,and uses the color touch screen to construct the human-machine interactive interface.Between the upper computer and the lower computer,the polling design is used to realize that multiple lower computers send data to the upper computer at the same time and the encrypted design is used to ensure the security of the data.Finally,the intelligent LED landscape lighting embedded monitoring system was tested and adjusted,the main operating interface and debugging results of the system were given,the function of real-time monitoring and alarming of the LED landscape lighting equipment was realized,and to ensure that the LED landscape lighting equipment operate safely,efficiently and reliably.
