Mobile terminal building collapse alarm system and method based on location technology

Abstract

The invention discloses a mobile terminal building collapse alarm system and method based on a location technology. The hardware comprises an MEMS acceleration sensor, an A / D conversion circuit, an MCU, a memory, a SIM card, a communication circuit, a communication antenna, an intermediate relay, a loudspeaker, a positioning circuit and a positioning antenna. The MEMS acceleration sensor is connected with the MCU through the A / D conversion circuit. The SIM card and the communication antenna are embedded in the communication circuit. The communication circuit is directly connected with the MCU. The positioning antenna is embedded in the positioning circuit. The positioning circuit is directly connected with the MCU. The coil of the intermediate relay is directly connected with the MCU. The loudspeaker is connected with a storage battery through the intermediate relay. The MEMS acceleration sensor transmits vibration data to the MCU. After the MCU determines that a building vibrates, a pin is closed, and the power supply of the coil of the intermediate relay is turned on. After the coil is electrified, the intermediate relay is closed. The electrified loudspeaker plays the prompt tone that the building has the risk of collapse. People can urgently evacuate from the building the first time after hearing the prompt tone.

Description

technical field [0001] The invention relates to the field of emergency device systems, in particular to a mobile terminal building collapse alarm system and method based on positioning technology. Background technique [0002] Causes of building collapses mainly fall into the following categories: [0003] In an earthquake, seismic waves are divided into transverse waves and longitudinal waves, which cause buildings to shake back and forth and up and down respectively. Buildings are subjected to forces from different directions, resulting in changes in load-bearing, uneven force, and then expansion of the amplitude, beyond its scope leading to collapse. [0004] Debris flow, large diameter stones carried by the debris flow will hit the building wall vigorously, resulting in local compressive failure of the wall or column. [0005] Floods, floods wash away the walls and foundations, resulting in erosion of the sediment, the walls or foundations are gradually hollowed out an...

AI Technical Summary

Problems solved by technology

At present, people have designed a variety of response devices or systems for building collapse accidents caused by various disasters. However, in real life, due to the high cost of these devices or the difficulty of installation and implementation, these designs are almost in a theoretical state. so people don't actually benefit
