Design And Implement Of One-Key Alarm System On Digital TV Set-top Boxes

With the full advancement of the “Tri-networks Integration”(integration of telecommunications networks,cable TV networks and the Internet)and the “Internet +”,two-way interactive digital TV set-top boxes have entered thousands of households and are becoming a vital medium for information communication in our modern life.Residents are also more and more accustomed to get all kinds of information through interactive TV,and various applications are emerging based on digital TV set-top boxes.Therefore,in the national implementation of the “Xueliang Project”(Public Security Prevention and Control Project)construction,it is quite urgent to build a one-key alarm system based on digital TV set-top boxes in accordance with the concept of “mass participation in preventing and controlling disturbances to public order” in the relevant instructions.The one-key alarm system based on digital TV set-top boxes is a new alarm mode which combines video monitoring and one-key alarming,and is different from the traditional telephone alarms,fire button alarms and outdoor emergency alarm posts.In addition to watching cable TV programs,residents can also view the real-time monitoring images through the digital TV set-top boxes and simultaneously make a quick alarm for help,so as to combine the monitoring images with the alarm information and facilitate grid managers to grasp and deal with emergency alarms as quickly as possible.Starting from the actual project requirements,this Paper focuses on analysis and research on the technologies related to video monitoring and one-key alarm based on digital TV set-top boxes,and finalizes the design and implementation of the one-key alarm system based on digital TV set-top boxes,mainly including such contents as follows:1.This Paper has analyzed the background and significance of developing the one-key alarm system based on digital TV set-top boxes.In accordance with the characteristics of the digital set-top boxes as well as the basic software and hardware conditions in the actual project,it has firstly determined the system architecture and operating environment,and detailed the key technologies used in the implementation of the system,including: B/S architecture,MVC design mode,LAMP architecture,front-end development technology and streaming media related technology.2.This Paper has deeply analyzed the functional requirements of the one-key alarm system based on digital set-top boxes,designed the overall architecture of the system,determined the system structure(including front-end alarm subsystem,back-end management subsystem and three-party interface subsystem),subdivided the functions of each subsystem,and designed the detailed functions and UI interfaces each functional module shall achieve.3.In this Paper,coding was used to have realized each functional module and interface of the one-key alarm system one by one based on digital TV set-top boxes;moreover,such functional module and interface have been displayed via some key codes and implementation pages.The functions realized are as follows: view the video monitoring images through digital TV set-top boxes,and complete quick alarms for help;grid managers can receive and handle alarm and help events through PC terminals,and can manage and count the system users,regional attributes,surveillance cameras and other information in an all-round way;visually display the location information of the surveillance cameras through the Baidu map interface,send the alarm help information and event disposal result information through the short message interface,and exchange the events through the “broad-linkage and micro-governance” tripartite platform.4.In this Paper,all the functional modules of the system have accepted tests for compatibility,functionality and performance.After verification,the system has successfully entered the stage for online trial operation.Finally,in accordance with the actual operation and users' feedback,the design and implementation of the whole system has been analyzed and summarized,with the prospect put forward for its next optimization.
