Design And Implementation Of Intelligent Equipment Manag Ement System For Sports Lawn

In the process of urban transformation,the development and maintenance of lawns and other green areas are important aspects of new life and new cities,where sports lawns are an important part.For traditional lawn management problems such as "old methods and old ideas",a management system integrating professional knowledge management and real-time human computer interaction is designed in this dissertation to improve existing management methods.This management system uses the software engineering and IoT(Internet of Things)technology to reform the information of traditional equipment.The main research contents of this dissertation are summarized as follows:(1)Building a framework for the overall development of software systems.With the underlying intelligent hardware,wireless communication technologies such as the bluetooth and infrared are used to implement upper-layer application software based on mobile terminal devices.Firstly,the system functional requirements are analyzed,and the system hierarchy and structure are divided.The system architecture is then designed.Due to the system involves hardware communications,the software layer and hardware layer interface compatibility issues have been comprehensively considered in terms of unified interfaces.In addition,the protocol compatibility of two different wireless transmission technologies in the communication process has also been considered.In terms of service resources,the resource oriented service of Web Service based on the Representational State Transfer Web is used to improve the standardization,applicability,and extensibility of the software systems.(2)Building a mobile application environment.In order to make the lawn management more intelligent,an improved mobile terminal architecture is adopted to develop a mobile application with lower coupling and more extensibility.This application can view lawn management related data in real time,remotely control smart devices,and write device addresses for devices.The device control process adopts the bluetooth and infrared wireless communication technology.In addition,for some mobile devices(models)without infrared function,which analyze the infrared waveform is analyzed,and a solution that uses the device's earphone hole to convert the audio signal to infrared signal is proposed,which greatly enhances software compatibility and scalability.(3)Building a lawn professional knowledge base.Firstly,the web crawler technology is used to capture the lawn-related data of professional websites,and the traditional paper data is electronized and supplemented by expert experience.Secondly,the key word matching model is constructed by selecting the proper word segmentation method,and the search ordering rules are determined by assigning weights to the warehouse data.Finally,the lawn professional knowledge base is established to provide professional basic information support for lawn management.In the end,the software system was designed and tested.Including the implementation of the software part and the realization of the hardware wireless communication part.The software part includes the design of the system E-R diagram,the design of the system model structure,the design of the system module and the design of the system database.The system design is inseparable from the implementation of the final system,which determines the integrity and robustness of the system.The system is written in C#and JAVA languages with the Microsoft SQL Server 2012 and Android Studio 2.0 environments.The three-tier architecture model is used to implement the client PC management software and mobile terminal software.This system is applied to the actual lawn management by a golf club in early 2017,which initially achieves the expected goal that the intelligent management of the lawn.
