| The rapid development of urban traffic is increasingly inseparable from the construction and application of traffic signal light systems.The role of traffic lights is to guarantee smooth traffic.However,due to the impact of the environment and the life expectancy abnormal working conditions may ba occurred randomiy.And the fault situation cannot be responded in time.The ultimate goal of the thesis is to break traditional manual inspection mode and improve the clear traffic.Using Django framework,this thesis proposes a comprehensive management system that can collect the real-time working data of traffic lights and timely feedback information,which can conduct information processing and analysis through the data management and control platform to effectively improve the level of refinement of signal light management.The development of system is based on B/S architecture,using the Django framework to achieve the visualization of real-time state information of the signal lights.An information platform is developed to creat,delete,update and select global information.The main tasks of this paper are as follows:1)By studying the operating environment of traffic lights,the Lo Ra module used to monitor the status of traffic lights.The collected information was uploaded to server through gateway,and the interaction between terminal and server adopted MQTT protocol.2)Based on Django technology,through the analysis of the signal light status monitoring real-time data specific,the appropriate background database and language are selected to build system.3)According to the analysis of software platform requirements and the platform framework,the system foreground-background and the realization scheme of software design are established.The Django framework is supplemented by Java Script and other front-end technologies to realize the data interaction between front and back.4)The platform is divided into different functional modules to realize a real-time,stable,and reliable system,in order to has good survivability and robustness.5)Environmental and functional testing of the system is conducted.Through the problems found,the system can be improved continually.The utility of system can also be enhance.The functional test results of the monitoring platform software show that the system meets the requirements and achieves the original design objectives. |
