Once the listened person sends sound, will produce the sound wave with energy, for example, on the object around sound wave is delivered to this energy by air (window or wall), cause the vibration of object, simultaneously, the signal that the monitoring signal reflector sends is delivered on object and produces corresponding the variation, then reaches vibration frequency analyzer analyzed after the monitoring signal receiver receives, final signal after by analysis is reduced to voice signal by recovery instrument, plays the effect of monitoring.
What this monitor for police device adopted is infrared signal or laser signal, can give full play to the advantage of two kinds of signals, obtains comparatively complete monitoring signal.
The accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation that Fig. 1 is an embodiment of the present invention;
In figure: 1-monitoring signal reflector; 2-monitoring signal receiver; The 3-vibration frequency analyzer; The 4-recovery instrument; The 5-player; The 6-wall.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
Embodiment:
As shown in Figure 1, be a kind of embodiment of monitor for police device of the present invention, this device comprises monitoring signal reflector 1, monitoring signal receiver 2, vibration frequency analyzer 3 and recovery instrument 4 successively.Wherein, the effect of monitoring signal reflector 1 is to launch monitoring signal; The effect of monitoring signal receiver 2 is to receive monitoring signal; The effect of vibration frequency analyzer 3 is that the monitoring signal that monitoring signal receiver 2 is received is analyzed; The effect of recovery instrument 4 is that the monitoring signal after vibration frequency analyzer 3 is analyzed is reduced to voice signal; In addition, can also connect a player 5 on recovery instrument 4, play back for the sound by after reduction, play real-time monitoring effect.
The using method of this monitor for police device is: monitoring signal reflector 1 is arranged on to the place that distance is monitored the suitable distance of target, and this distance is that the monitoring signal sent by monitoring signal reflector 1 determines.When the listened person sends sound, will produce the sound wave with energy, on object around sound wave is delivered to this energy by air (for example, on wall 6 or window), cause the vibration of wall 6, simultaneously, the monitoring signal that monitoring signal reflector 1 sends is delivered on wall 6 and produces corresponding the variation, reach on vibration frequency analyzer 3 and analyzed after monitoring signal receiver 2 receives again, final monitoring signal after by analysis is reduced to voice signal by recovery instrument 4, plays the effect of monitoring.In addition, the above-mentioned monitoring signal reflector 1 be mentioned to, monitoring signal receiver 2, vibration frequency analyzer 3 and recovery instrument 4 are known technology in the art, do not repeat them here.
