Abstract: Earthquake on-site work is an important part of earthquake emergency response work, which is of great significance for guiding emergency rescue, resettlement of disaster victims, restoration and reconstruction, scientific research, and other work. This system has been designed and developed to address the low level of informatization of the earthquake field work team after its departure, as well as the lag in sharing information between personnel, vehicles, materials and equipment. The system can be divided into three subsystems: data collection and transmission, information storage management, and information visualization display. The "Android mobile terminal APP+web" technology method is used to effectively achieve real-time display of the vehicle speed and position, as well as personnel loading and unloading Real time recording of equipment loading and unloading, audio and video instant messaging, and other system functions. The system has been applied in the emergency response work of the Yangbi 6.4 magnitude earthquake site of the Yunnan Earthquake Agency, providing assistance for the efficient implementation of earthquake site work, improving the informatization level of earthquake site work, and meeting the information exchange needs of collaborative command and comprehensive scheduling between the front and rear parties.
