Abstract
The invention provides a high-sensitivity multi-direction collision accident detection method, wherein a multi-direction collision sensor is arranged in a detected object, and the sensor comprises: the cavity wall of the closed cavity is also provided with an insulating gap, a deformable conductive inertial body is injected into the cavity, a contact is arranged on the gap and leads out of the shell to be used as a leading-out electrode, and when the shape of the inertial body is changed under the action of external force and is extruded into the gap, the contact is conducted; when the shape is restored, the contact is opened. The detection method can detect high-sensitivity collision signals in multiple directions, and can be used for accident feedback of manned or unmanned aerial, aerospace, underwater or overwater operation robots, ships, submarine reef touch and the like and accident recording of object collapse, explosion, collision, smashing, automobile knocking and the like, or accident analysis, automatic control, military equipment, scientific experiments, industrial automation and the like.
Description
Technical field
The present invention relates to the detection method of a kind of collision checking method, particularly a kind of high-sensitivity multi-direction collision accident.
Background technology
The impact microphone of the air bag of existing automobile, form by coasting body and spring and contact, because volume is big, and directive property is good, so being used as the two dimension collision sensing must need 4 (front, rear, left and right), detect 8 or more orientation if desired, obviously expense is higher, and it is bigger to take up space.Particularly, therefore, be difficult for directly being welded on the circuit board using because it detects is large impact power.In addition, want to detect a plurality of collision bearings, especially slight degree of crash signal with this conventional method and be difficult to, because when improving the detection sensitivity of crash sensor, just be difficult to take into account the consistency of each its dynamics of collision bearing and the harmony of action.
Summary of the invention
One of purpose of the present invention: be exactly to simplify crash sensor structure and detection method, realize the highly sensitive effective detection of multi-direction collision accident, it not only guarantees the harmony of each orientation action, but also guarantees the consistency of each bearing sensitivity and good repeatability and antifatigue and durability.
Two of purpose: not only dwindle the collision detection sensor volume, also reduced cost, but also improve reaction speed and detection sensitivity.
To achieve these goals, the present invention proposes a kind of detection method of high-sensitivity multi-direction collision accident, described inside at testee is equipped with a multi-faceted crash sensor, this transducer comprises: airtight cavity 6 and chamber wall also are provided with insulation space 4, in cavity 6, be marked with deformability conduction coasting body 5 (as: mercury), in described space 4, be provided with contact 1 or 2, and the described enclosure that goes between, as extraction electrode, when coasting body 5 is subjected to active force and changes shape and get into space 4, contact 3 and 1 or 3 and 2 conductings; During recovery of shape, the contact disconnects.
Figure is further described the present invention below in conjunction with symbol:
Description of drawings
Among Fig. 1: 1 is left contact; 2 is right contact; 3 is public pole plate; 7 is circuit board.(this figure is 8 orientation of level collision detection method).
Fig. 2 is a cutaway view: 1 is left contact pin; 3 is public pole plate pin; 4 is the space; 5 are deformability conduction coasting body; 6 is cavity; 8 are sealing.
Among Fig. 3: periphery is a contact; The centre is a contact.(this figure is the universal collision detection method of level).
Fig. 4 is a double-sided printed-circuit board, and among the figure, each pin by outer shroud to the connection order of interior ring is: 9,10,11,12, and the center is a public pole.(this figure is the universal collision detection method of 4 kinds of different dynamics)
Embodiment
At first point out: mercury is than great, and the auto-convergence characteristic is good because its quality is more little tends to spherical more, and spherical mercury not only surface tension is big, good springiness, therefore, this deformability conduction coasting body first-selection is a mercury, its diameter is preferably got between 3mm to 2mm.
Operation principle: see Fig. 1 and Fig. 2.Collision make 5 distortion of deformability conduction coasting body and partly compression clamp-on space 4, withdraw from recovery again rapidly because of effects such as slope and outside autohemagglutination power and tension force, elastic force, make contact 2 or 1 and middle public pole plate 3 between produced the overall process of conducting and disconnection.
The selection of the sensitivity of this transducer and coasting body 5, quality, and the spacing of space 4 width, the gradient, shape and contact etc. is relevant.
Point out that in passing the present invention also can be used as centrifugal force sensing and detection, i.e. centrifugal switch.
Claims (2)
1, a kind of detection method of high-sensitivity multi-direction collision accident, described inside at testee is equipped with a multi-faceted crash sensor, this transducer comprises: airtight cavity 6 and chamber wall also are provided with insulation space 4, in cavity 6, be marked with deformability conduction coasting body 5, in described space 4, be provided with contact 1 or 2, and the described enclosure that goes between, as extraction electrode, when coasting body 5 is subjected to certain directive effect power and changes shape and get into space 4, contact 3 and 1 or 3 and 2 conductings; During recovery of shape, the contact disconnects.
2, according to the detection method of the described a kind of high-sensitivity multi-direction collision accident of claim 1, it is characterized in that described deformability conduction coasting body 5, can be any flexible conductor, be best with mercury.
