The invention discloses an electronic monitoring alarm device for the early stage of an earthquake. The electronic monitoring alarm device comprises a 3V direct-current power supply, an earthquake signal monitoring circuit and a differential amplification and buzzer drive circuit. According to the device, an NPN type transistor bridge circuit serves as the core circuit, a buzzer makes a sound immediately once a monitoring probe is touched, and false alarms or neglected alarms can be avoided fundamentally. According to the technical scheme, the circuit structure is simplified, the manufacturing difficulty and the manufacturing cost of the monitoring device are lowered, and the requirements for high sensitivity of monitoring the early stage of the earthquake and reliable working performance are met. The electronic monitoring alarm device for the early stage of the earthquake is suitable for occasions such as families, schools and hospitals in earthquake-prone areas.
Description
technical field [0001] The invention belongs to the technical field of electronics and earthquake monitoring, and relates to an early electronic monitoring and warning device for earthquakes. 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. If the earthquake can be achieved in the early stage of the earthquake, if more than ten seconds can be won, many people may pass by the disabled or the god of death. 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. [0003] The early electronic monitoring and warning device for earthquakes described in the present invention can instantly activate the sound alarm when the first earthquake wave is detected in a very short time in the...
