The Design And Implementation Of Intelligent City Training System Based On Internet Of Things

The Internet of things is the national tera-scale strategic emerging industry and is one of the five high-end growth industries that Sichuan province emphatically develops. A large number of technical talents, who are familiar with the industry standards and technical specifications, and possess the implementation skills of smart city projects, and strong technology development and innovation ability is urgently needed in the process of the development of the Internet of things industry, especially promoting the construction of smart city.According to the related professional practice teaching needs in higher vocational colleges, a kind of design scheme and its realization method of the training system of smart city based on Internet of things are put forward. Firstly, with the application technology major of Internet of things set up by many higher vocational colleges in Sichuan province as an example, the function demand of the training system is analyzed from the talents cultivation orientation. Secondly, in accordance with the functional requirements and the relevant industry standards, the technical architecture and the function layout of the system are determined. Finally, a simulation smart city training system is developed through the integrated use of sensors, ZigBee wireless sensor network, computer network, C/C# / Java application development technology.The contents of the thesis are divided into five parts:Part one:demand analysis and overall design. According to talents training targets of related majors of Internet of things set up by the higher vocational colleges in Sichuan province, the function demand of training system is analyzed; the technical architecture is determined; the function layout is planned.Part two:perception layer system development. First of all, with CC2530 and multiple sensors as the core, the hardware module that meets the function demands, including urban lighting monitoring, traffic scheduling, fire control and security monitoring, environment monitoring and hydrological monitoring is designed. Then, driver and single-chip microcomputer control program are developed for each sensor module based on Z-STACK protocol STACK.Part three:transmission layer system development. First of all, ZigBee-WiFi gateway is designed based on STM32 MCU, WiFi communication module and CC2530 module. Next, ZigBee wireless transport layer software and STM32 software operating in the ZigBee-WiFi gateway are developed.Part four: application layer subsystem development. By taking hydrological monitoring system as an example, the database table based on SQL Server 2005 is designed according to the functional requirements. Then, TCP service acquisition software operating on PC and development methods of software based on web application display are introduced.Part five:system function test, popularization and application. The main functions of the training system and its application in related colleges are introduced. Next, the existing deficiencies and the improvement direction are analyzed.
