Design Of Alarming Subsystem In Urban Emergency Response System

With the development of China's economy and the continuous expansion of city, the emergencies and the unexpected events, such as fire, traffic accidents, natural disasters, are continually increasing. City Emergency sharing platform, is the Police 110, Fire 119,120 medical emergencies, traffic police and other alarm receiving unit 122, scheduling systems, flood control, forest fire, earthquake, air and water, electricity, gas and other public utilities, emergency assistance into a unified command scheduling system, sharing resources, cross-sectored, inter-district and the different kinds of police co-ordination between the unified command, and convenient to the public emergency services. Practice shows that, through the Emergency Response System, the city police assistance call handling capacity increased 6 times, the system command to expand the coverage area of more than 100 times.The subsystem of Emergency Response Alarm and Command is shared platform front-end, and other subsystems are closely linked, is a concrete realization of user business needs. Response alarm subsystem not only provides Alarm, alarm processing, control, linkage and other stages of processing power, can also closely cooperate with other subsystems, corresponding to complete the work.Papers on Urban Emergency sharing platform in emergency control system in a study of response alarm subsystem, described in detail the design and response alarm subsystem implementation. First of all, according to the design of response alarm subsystem goals and needs, a detailed analysis of its major business processes. Then proposed response alarm subsystem design, and its main technical solution is described, in particular, the linkage mechanism described in the design. By using the event synchronization and interlocking design ensures the reception and handling client data accuracy and uniqueness. Final details of the key to achieving response alarm subsystem. Structural organization of the data in the system, this article through the use of parent-child tree code generation algorithm, and view the table tree generation algorithm to complex hierarchical data structures, greatly increased the availability of data reuse, saving data storage space.
