| What fire brings life to human society is enormous disaster.An important reason is that the people trapped in the fire pit can find it difficult to escape as once.On the other hand,fire rescue centers cannot be informed of the scene,which results in long delays and slow evacuation problems.However,such disasters should be able to be resolved through effective methods.Through simulation experiments,we were compared before and after the improved algorithm,a new algorithm to make results more accurate positioning.Finally,the article now WIFI indoor positioning to be considered for emergency fire and improved positioning factors are discussed and put forward the concept of introducing fire special AP points.In order o find a low cost,high efficiency way of data transmission,I turned my attention to the advanced WIFI technology.On the other hand,in order to allow users to enjoy portable operation,the design has chosen Android platform for development.I made this application that can gathered the WiFi data around the user’s current location,and upload them to the PHP server using JSON method.It can also call for positioning and guiding request.The server will then compare the data with those stored in the database,and give back exact location information.As a result,the user will be able to determine their location visually and also to escape from the fire according to the guidelines.In addition,a management interface is also designed for decision-making command center to manipulate.Practical application of this application can greatly increase the efficiency in escaping and rescuing,and further reduce the losses caused by the disaster.Therefore,a strong practical significance is implied. |
