At the earthquake early period of origination, ripple appears vertically shaking, and the destructive power of this ripple that shakes is less, after a while, just can produce the bigger transverse vibration ripple of destructive power.Simultaneously, different earthquake magnitudes or with shake heart distance, the intensity of vibration is different.The utility model had both been considered the different warning indications of different earthquake magnitudes such as level Four and Pyatyi, considered the alternative sounds indication of detected vertically the shake ripple and the ripple that laterally shakes again.When sensing earthquake when taking place, weight 8 will up-down vibration and is driven suspension wire 6 swings, and its displacement increases with earthquake degree, and this device is repeated fine.The utility model is set and to be equivalent to earthquake below three grades and will not to respond to harmless, and to be equivalent to four, the Pyatyi earthquake than strong motion, distinguish and report to the police by consequent weight being moved classification.

In the up-down vibration position transducer 10 of the present embodiment shown in Fig. 3, by the aluminum metal sleeve 12 of copper suspension wire 6, be suspended on the round magnetic post 13 of copper suspension wire 6 ends in the middle of comprising; Aluminum metal sleeve 12 inwall both sides, with circle magnetic post 13 at interval different distance be respectively equipped with a

position transducer

19 and 20 by the magnetosensitive switch, and these sleeve 6 upper ends connect with spring 7 ends, lower end and are connected with weight 8 by copper suspension wire 32 down, make that sleeve 12 can be with weight 8 up-down vibration; Circle magnetic post 13 directly is connected in sleeve 12 cavitys by suspension wire 6, and and cavity inner wall between certain interval is arranged, make it in cavity, freely to slide up and down, its motion is not subjected to the influence of weight 8 vibrations.Like this according to the magnetic position sensing principle, the resolution of the up-down vibration position transducer of being made up of above-mentioned parts just can reach the up-down vibration position smaller or equal to 0.1 millimeter.

Fig. 4 shows the structure situation of the horizontal hunting position transducer in the present embodiment, Fig. 5 shows the position relation between magnetosensitive switch 21-24 and the ring-shaped magnet 18, and said horizontal hunting position transducer 9 comprises annulus 15, following annulus 16, magnetosensitive switch 21-24 and ring-shaped magnet 18; Last annulus 15 is fixed on the middle and upper part of metal mainstay 4 by its fixed arm 33, East, West, South, North location in last annulus 15 lower surfaces is fixed one or two group of magnetosensitive switch respectively, only show one group four magnetosensitive switch 21-24 herein, corresponding to four corners of the world four direction; The bearing center of circle of following annulus 16 is fixed on the suspension wire 6, and four orientation, the corresponding four corners of the world of end face and magnetosensitive switch 21-24 are fixed with four sections ring-shaped magnets 18 thereon, following annulus 16 will be swung with the swing of suspension wire 6, and then causes one or several action among the magnetosensitive switch 21-24 that is located on the annulus 15.Like this according to the magnetic position sensing principle, the resolution of the horizontal hunting position transducer of being made up of above-mentioned parts just can reach on any one direction the swing displacement smaller or equal to 0.1 millimeter.

In the utility model embodiment warning circuit shown in Fig. 6 and Fig. 7, the magnetosensitive switch 19 that comprises vertical vibration displacement when being used to respond to slight earthquake (4 grades) takes place, be used for responding to the magnetosensitive switch 20 of vertical vibration displacement when slightly earthquake (5 grades) takes place, when being used to respond to earthquake and taking place on the surface level first, second, the sensing magnetosensitive switch 21-24 of third and fourth direction swing displacement, described magnetosensitive switch 19 is connected with delay unit 31, magnetosensitive switch 20 is connected with change of voice control module 25, magnetosensitive switch 21-24 is connected with modified tone control module 26, described delay unit 31, change of voice control module 25 and modified tone control module 26 are connected respectively to chimes of doom generating unit 27 and led display unit 30, and the output terminal of chimes of doom generating unit 27 is connected to loudspeaker or other phonation unit 29 by amplifying unit 28.Its principle of work is such magnetosensitive switch 19-24 (IC1, IC2, IC6 ...) move according to the motion of sensor, when magnetosensitive switch 19 is triggered, chimes of doom generating unit 27 sets out after time delay circuit unit 31 is delayed time, this unit (IC4) major function is finished by the KD9561 speech chip, when the SEL1 of this chip pin meets V _SSThe time chimes of doom be ambulance sound, expression is equivalent to the level Four earthquake and takes place; SEL when this chip ₁Pin meets V _DDThe time chimes of doom be fire engine sound, expression is equivalent to the Pyatyi earthquake and takes place.For realizing distinguishing earthquake magnitude with alternative sounds, between the magnetosensitive switch 20 of sensing earthquake more than 5 grades and 5 grades and sound generation unit 27, be provided with the control module 25 of changing voice, detailed process is like this, when up-down vibration position transducer 10 fixes on suitable level Four earthquake sensitive position, because of relative its vibration trigger circuit of circle magnetic post, output short-circuit makes IC3 export the operating voltage of IC4; IC1 is released the back output open circuit, and IC3 just presses R ₅C ₁The parameter time-delay made after the IC4 work in ten minutes, if vibrations continuation triggering IC4 does not just stop to report to the police; The effect of IC2 is to set when being equivalent to Pyatyi earthquake generation, changes the chimes of doom of IC4; When vibrations are that IC2 is not triggered four between Pyatyi the time, output open circuit, Q conducting are SEL ₁Pin meets V _SS, the IC4 circuit can only be exported ambulance sound.As when suitable Pyatyi seismic oscillation triggers IC2, output short-circuit Q disconnects, i.e. SEL ₁Pin meets V _DD, the IC4 circuit is just exported fire engine sound.Simultaneously, LED unit 30 can be set along separate routes and indicate earthquake magnitude and shake position direction.

When the vibrations that detect horizontal direction, be triggered by among the magnetosensitive switch 21-24 one or several, drive modified tone control module 26, resistor of the i.e. outside parallel connection of voice IC in sound generation unit 27 changes occurrence frequency, thereby the modified tone when realizing the occurred level swing (reduces time constant, come to a point sharpen) report to the police.
