Research And Implementation Of Key Technology Of Road Emergency Management System

With the increase of the car numbers, Vehicles which are driving on the road willinevitably encounter some problems such as anchor, tire puncture and so on, toeliminate the problems of road travel immediately is particularly important for the carowners, so the road rescue services applications have emerged at this point. carowners at the present stages usually choose to call rescue for requesting assistance,however，with the development of the network and the popularity of smart phones, thetraditional telephone assistance is not the only choice for the rescue mode any more,and the telephone assistance still exists some defects. For example, if the people whois waiting for rescued is not clear for the accident site and the surroundingenvironment, it is bound to be difficult to clear their rescuers scene for people, so therescue will be delayed. By installing application software on the phone to launch therescue is not only convenient, but also be better to locate the accident location andcan accurate pass the details of the vehicle scenes.This paper study on road rescue management system, using push technology,communication with the client and rescue staff client, for user initiated rescue request,put forward a kind of rescue task allocation strategy, automation, intelligent allocationof rescue resources, improve the work efficiency of the operator. Systemadministrators can also through this system of integrated information management thesystem operator, rescue vehicles and rescue orders.The main research contents of this paper are as follows:(1). The research and implementation of the operator allocation strategy.Considering that there are multiple operator in the whole system, in order to make theuser’s rescue request can be processed efficiently and quickly, at the same time inorder to balance the system operator’s daily workload, for every rescue request,reasonable allocation to different operators. The strategy takes into account the operator online, the idle state attribute state value, in the state of system operationprocess will be recorded in the memory, and maintain the use of multithreadingtechnology. In task assignment using this strategy to choose the optimal operator, andthe use of the browser MQTT push technology, will rescue the request to the operator.(2).The design and implementation of a rescue vehicle allocation strategy. whenthe user initiate the request to rescue, the operator need assign a rescue vehicle for therequest. This allocation strategy is also a multi thread environment. The operator inthe assignment, first using the allocation strategy select the target rescue vehiclesfrom a rescue vehicle in the collection, according to the real-time information oflatitude and longitude rescue vehicles, and combined with the Web map technologywill be the rescue vehicle is displayed in the assignment map interface, convenient foroperator convenience in operation at the same time, to ensure that the rescue staff toget the task information timely, rapidly to the rescue, and improve the system of theinteractive experience.(3).Combined with the general requirements of the project, design andimplement a road emergency management system. The main research is focused onthe design of the goals, emergency rescue management system architecture, theoverall flow, rescue function structure and the database design associated with therescue process. And with a rescue process as the main line, introduced the detaileddesign and implementation of the main function in the system, and carries outsimulation experiments on the rescue process, according to the analysis of the testresults, the system achieve the original design goals, not only improve the rescueefficiency, but also improve the efficiency of the staff, and reduce the average waitingtime for users.
