Abstract
The invention relates to a pendulum mass-spring hammer head type urban public automatic impending earthquake warning system, which is mainly mixed by groups of various pendulum masses, and uses the collision generated by the shaking of a long rod and a spring hammer head with surrounding fixed contact terminals as the warning datum, belonging to the shaking trigger circuit closing type impending earthquake warning technology. When in ready, a warning circuit is off, and the warning circuit is closed to send out warnings and spread signals to surrounding towns when in operation. The invention can be independently used as a public automatic impending earthquake warning system of a county town, a town and a county, and can simultaneously send out various warnings. If the automatic warning device is installed on one town, warning can not be sent out when the pendulum mass is still, namely that buildings can never fall down in the state. And the warning device sends out warnings when the pendulum mass starts to shake, which means the surface shaking, as the premonition of an earthquake. Thus the automatic warning device can be installed to evacuate people in advance before people directly feel the earthquake.
