Description
Technical field
The present invention relates to a kind of seismograph, particularly relating to a kind of the seismograph simulated demonstration instrument and the control system thereof that detect seismic process for demonstrating seismograph.
Background technology
Seismograph is the instrument of the first in the world frame monitor earthquake that the Eastern Han Dynasty of China scientist Zhang Heng invents.When there is earthquake somewhere, the Longkou of seismic direction occurs and will to spue copper ball, in the mouth, people just can know the direction that earthquake occurs to fall copper toad below.In some current earthquake museums, seismograph generally adopts simple mode to demonstrate as static display or by staff, spectators cannot participate in the process experiencing seismograph monitor earthquake, greatly reduce the visit interest of spectators and the understanding to showpiece, disclose a kind of seismograph simulated demonstration instrument in patent CN200720192584.2 for this reason, it comprises cylindrical shell, carving dragon, bead, toad, base, connecting rod is connected with described pedal with pedal lower end, after pushing down on the pedal, connecting rod is action thereupon, now bead falls in toad mouth from the mouth of carving dragon, complete whole presentation process.But this seismograph simulated demonstration instrument due to its principle of work be by the action of pedal linkage control link, for beholder, this course of work differs rich far away with seismographic principle of work, can not play the actual whole process controlling respective direction bead by detecting vibration and drop.
Therefore, a kind of seismograph simulated demonstration instrument demonstrating the seismographic course of work and principle of work is needed.
Summary of the invention
The object of this invention is to provide a kind of analog demonstration instrument of earthquake instrument control system, this analog demonstration instrument of earthquake instrument control system is controllably shaken instrument simulated demonstration instrument and is demonstrated whole earthquake observation process according to vibration signal, demonstrating visual, accurately, beholder is made to fully understand seismographic Cleaning Principle and process.
Another object of the present invention is to provide a kind of analog demonstration instrument of earthquake instrument, and this analog demonstration instrument of earthquake instrument can demonstrate whole earthquake observation process according to vibration signal, demonstrating visual, accurately, makes beholder fully understand seismographic Cleaning Principle and process.
To achieve these goals, the invention provides a kind of analog demonstration instrument of earthquake instrument control system, involving vibrations testing circuit, electric pushrod and controller, described vibration detection circuit involving vibrations sensor, for gathering in preset range the vibration signal trampled and cause; Electric pushrod is for promoting the bead in analog demonstration instrument of earthquake instrument; Controller comprises control module, and described control module controls described electric pushrod action according to described vibration signal.
Compared with prior art, analog demonstration instrument of earthquake instrument control system of the present invention controls corresponding electric pushrod action by the vibration signal that vibration transducer detects, realize demonstrating whole earthquake observation process according to vibration signal, demonstrating visual, accurately, beholder is made to fully understand seismographic Cleaning Principle and process.On the other hand, the present invention controls the action of bead by electric pushrod, relative to traditional connecting rod, this electric pushrod Absorbable organic halogens bead is launched, bead is made to fall in toad mouth from Long Zui under certain dynamic action, bead is prevented to be stuck in the problem that cannot drop in imperial mouth, failure rate is low.
Preferably, described control module produces rising control signal according to described vibration signal, control described electric pushrod according to described rising control signal to rise from meta, until described electric pushrod rises to a high position and produces decline control signal after first schedule time, control described electric pushrod according to described decline control signal to decline from a high position, until described electric pushrod drops to low level and produces rising control signal after second schedule time, control described electric pushrod according to described rising control signal to rise from low level, until described electric pushrod rises to meta after the 3rd schedule time.Because the concrete speed of electric pushrod is controlled, therefore the present invention directly controls the action of electric pushrod and the position of bead by the schedule time of presetting, without the need to whether arriving bottom, meta and a high position by special detecting element detection validation electric pushrod, also whether original position is got back to without the need to detecting bead, make whole analog demonstration instrument of earthquake instrument Control system architecture simple, cost is low.Wherein, first schedule time, second schedule time, the 3rd schedule time are the electric pushrod preset and arrive a high position from meta, arrive low level and three times pre-estimated from low level arrival meta from a high position.
