Abstract

The invention discloses an early stage acousto-optic alarm device for early stage of earthquake occurrence, comprising a 12V DC power supply, an earthquake signal monitoring and voltage-dividing circuit, a voltage comparison circuit, and an electric level amplification and acousto-optic alarm circuit, wherein the model of an operation amplifier ICI in the voltage comparison circuit is CA3140. Earthquakes occurred at night can post huge threats to people's life because people are resting in the rooms. If people can get few more seconds to escape upon the moment the earthquake just happens, many people can be prevented from disability and death. The early stage acousto-optic alarm device for early stage of earthquake occurrence uses the operation amplifier as a core member, the buzzer makes sound as soon as the monitoring probe is trigger, and the mistake report and failure to report can be substantially eradicated. The invention simplifies the circuit structure, reduces the manufacture difficulty and cost of the alarm device, and realizes the requirement for high sensitivity and reliable performance in earthquake monitoring.

Description

technical field [0001] The invention belongs to the technical field of electronic technology and earthquake forecasting, and relates to an early sound and light alarm device for earthquake occurrence. Background technique [0002] Earthquake takes place at night, and people are all resting in the room, and this is maximum to people's life hazard degree, makes people hard to guard against. Earthquake is an irresistible natural disaster with a wide range of damage, great harm to life and property. So far, scientific knowledge has not effectively grasped the occurrence and forecasting laws of earthquakes. If it can be done in the early stage of the earthquake, if more than ten seconds can be won, many people may pass by with disability or death. [0003] The early acousto-optic alarm device of the earthquake occurrence of the present invention can monitor the first earthquake wave in a very short time in the early stage of an earthquake of magnitude 4 or above, and instantly s...
