LBS based disaster and emergency management

In recent years, with the occurrence of more and more natural disasters and emergencies, China has also been greatly affected by that without exception. Wireless communication technology is playing an important role in disaster and emergency management. In current applications, mobile communication network, as the main key technology, have been used to deal with disasters and emergencies. However, mobile communication network application will be subject to certain restrictions when ground communication facilities are severely destroyed. In response to this situation, a new solution need to be worked out and a platform for disaster and emergency management should be built. The most important technology in the solution is Location Based Service, which is based on satellite communication and wireless communication. In this paper, the components of LBS and their applications in disaster and emergency were discussed. Meanwhile, the overall framework and function modules of the disaster and emergency management system were given. There are two main communication forms in response to different circumstances: the first one mostly depends on wireless communication; the other one relies on satellite communication, satellite communication (such as communication satellites and COMPASS system) would be an alternative method when wireless network is useless. COMPASS system is compatible with positioning and simple communicating function, which can play great role when communication satellites are busy or blocked. At the same time, tasks can be allocated to mobile users and managed by disaster and emergency management center. It can also receive data of multitudinous formats transferred from mobile user. Many tests approached under the platform proved that it is a useful solution for disaster and emergency management.
