Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of emergency lifesaving equipment, in particular to a safety protection system for earthquake. BACKGROUND

[0002] Earthquake is a kind of natural disaster with strong burst and large destructive, which is caused by the rapid release of energy in the crust. With the acceleration of urbanization, high-rise buildings and dense building groups are built in modern cities, which makes it difficult for people to escape from buildings when an earthquake occurs. Strong earthquakes can cause building structures to collapse, crack, or internal components to fall and shift, thereby causing direct harm to people in the form of pressure, collision, poking, and squeezing, resulting in significant casualties. Especially when a destructive earthquake occurs at night, people are in a state of sleep, have low alertness and short reaction time, and often have difficulty avoiding danger effectively, resulting in more tragic loss of life and property.

[0003] At present, in order to cope with earthquake disasters, various safety protection facilities have emerged, among which the lifesaving capsule / safe house is a common one. This kind of device is usually set inside the building or as an independent unit, which provides a temporary safe space through a solid structure when an earthquake occurs, and resists collapse and falling objects. However, the existing lifesaving capsule technology has exposed a significant defect in practical application: during the critical "golden 72 hours" rescue period after the earthquake, they often become "information islands".

[0004] Specifically, the main function of the traditional lifesaving capsule is focused on "passive protection", that is, to ensure the physical safety of the survivors in the capsule, but it generally lacks intelligent functions for effective and active communication with external rescue forces. When an earthquake causes a building to collapse completely or partially, the lifesaving capsule may be buried deep in the ruins, and the survival status of the survivors inside (such as whether they are alive, injured, or the number of people) and the precise positioning information of the lifesaving capsule cannot be known by external rescue personnel in time. This leads to difficulties in rescue work: on the one hand, the trapped people are under great physical and psychological pressure in the dark and closed space, and their lives and deaths are unknown; on the other hand, the rescue team needs to conduct blind search and excavation in a large area with high risk on the vast ruins, which is inefficient, not only may miss the best rescue opportunity, but also may cause secondary harm to potential survivors due to improper operation. SUMMARY

[0005] The purpose of the present application is to provide a safety protection system for earthquake to solve the problems existing in the prior art and improve the success rate of earthquake rescue.

[0012] Preferably, the environment sensing unit comprises an inertial measurement unit, a light sensor, and an air pressure sensor. The control unit comprises a main control microcontroller and a power IC in signal connection with the main control microcontroller. The rechargeable battery is connected with the power IC signal, and the inertial measurement unit, the light sensor, the air pressure sensor and the display screen are connected with the main control microcontroller signal.

[0013] Preferably, each of the protective cabins is provided with an intercom system, which comprises an inner microphone, an inner speaker, an outer microphone and an outer speaker, all of which are connected with the main control microcontroller signal, the inner microphone and the inner speaker are arranged in the cabin body, and the outer microphone and the outer speaker are arranged on the outer wall of the cabin body.
