A system for determining the location of buried-shifted building groups

Abstract

The present invention relates to a system for determining the position of buried-shifted buildings, which includes several emergency calling terminals and search and rescue terminals; The connection line of the points can cover the position of the rear edge of the building group; each of the emergency calling terminals has a unique coded serial number, which can be identified by the search and rescue terminal. After the call for help terminal is triggered to work, it can calculate its own displacement information and transmit a signal; the search and rescue terminal stores the initial position of the call for help terminal, which is used to communicate with nearby call for help terminals, obtain its coded serial number and displacement information, and combine The initial location of the emergency calling terminal is used to calculate its current location information. The invention innovates the traditional search and rescue mode and thinking, can effectively overcome the shortcomings of the existing rescue positioning methods in disaster environments, has high work efficiency, can win valuable time for search and rescue, and save a lot of manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of disaster search and rescue, in particular to a system for determining the position of buried-shifted building groups. Background technique [0002] Disasters such as large-scale landslides, mudslides, and avalanches often cause buildings to be buried, and even lead to the movement of surface buildings, which brings great difficulties to the rescue of people in deep-buried buildings. The landslides in Maoxian County, Sichuan Province on June 24, 2017 and the landslide disasters in Shuicheng County, Guizhou Province on July 23, 2019 caused huge damage to people and property. One of the difficulties in the rescue is that the buildings buried and moved by the landslide cannot be determined The specific location, that is, the rescue target is not clear, resulting in low search and rescue efficiency; another difficulty is that the actual conditions such as pore water pressure, temperature, and humidity inside t...

[0002] Large-scale landslides, mudslides, avalanches and other disasters often cause buildings to be buried, and even lead to the movement of surface buildings, which brings great difficulties to the rescue work of people in deep-buried buildings

The landslides in Maoxian County, Sichuan Province on June 24, 2017 and the landslide disasters in Shuicheng County, Guizhou Province on July 23, 2019 caused huge damage to people and property. One of the difficulties in the rescue is that the buildings buried and moved by the landslide cannot be determined The specific location of the disaster deposits, that is, the rescue target is unclear, resulting in low search and rescue efficiency; another difficulty lies in the inability to grasp the actual conditions such as pore water pressure, temperature, and humidity inside the disaster accumulation body, and to formulate a rescue plan in a targeted manner

However, this form is extremely limited

It is unrealistic for people in potential disaster risk areas to generally obtain rescue equipment, and it is even more impossible to wear it in real time. At the same time, the size of portable products is limited, and the signal transmission power is obviously limited, which often cannot be received by surface rescue equipment.

Therefore, this type of equipment still cannot meet the needs of disaster scene rescue work

[0005] On the other hand, disasters such as landslides, mudslides, and avalanches are characterized by strong suddenness, and the time and space of occurrence cannot be effectively predicted. Therefore, it is difficult to achieve real-time measurement of the disaster body itself, and rescue work can only According to the current status of the accumulation body after the disaster, the movement of the disaster and the process of burying and moving the building can be reversed; it is also impossible to obtain important characteristic parameters of the disaster body itself, such as key information such as pore water pressure, temperature, and humidity inside the disaster body
