Principle of work of the present invention is:

In the obliquity sensor 1, surface-mounted integrated circuit 36 (see figure 1)s and obliquity sensor 2 (seeing Fig. 3 A-A) have been comprised in the shell 2, surface-mounted integrated circuit 36 (see figure 1)s are removed obliquity sensor switch 8,9,39,41,42,43,45,46, and other electronic devices and components all concentrate on the surface-mounted integrated circuit 36.In the obliquity sensor cylinder with connecting link 7 be the center in the dead ahead, dead astern, front-left, front-right, left front, right back, left back, eight directions in right front be uniform-distribution with eight obliquity sensors 107,108,109,110,111,112,149,150 (seeing Fig. 3 A-A) respectively, the structure (see figure 3) of the obliquity sensor switch 9 of the obliquity sensor switch 8 of front-left, front-right wherein, 107 corresponding dead asterns 108, dead ahead in like manner, 109 corresponding right backs 110, left front, 112 corresponding left backs 111, right front.Connecting link 7, georama 32, georama 31, connecting link 33, solid shot 35 (see figure 3)s have been combined into a single pendulum, suppose when device occurs being tilted to the left because of various situations, single pendulum is swung in real time, connecting link 33 contacts with the baffle plate 11 of front-left, pole 26 is clockwise rotated according to the body sway degree, obliquity sensor switch 8 (see figure 3)s change into the analog voltage signal that is complementary with pole 26 rotational angles, and pass to the topworks of information process unit or device.In like manner, corresponding pole 26,27,113,114,115,116,117,118 is the angle that the center rotation is complementary with obliquity sensor 107,108,149,150,109,110,111,112 respectively when installing to dead ahead, dead astern, front-left, front-right, left front, right back, left back, right front inclination, and 107,108,109,110,111,112,149,150 are converted into the analog voltage signal that is complementary with corresponding rotational angle again.

In the displacement transducer 10, shell 83 is by connecting link 103,104,105,106 with displacement transducer switch housing 82 immovable fitting (see figure 2)s, in displacement transducer 10, connecting link 97 and the associated mechanisms immovable fitting of installing, driving connecting link 98 when the associated mechanisms vibration of installing moves up and down, connecting link 97 drives fulcrum 102 again, fulcrum 102 drives moment of torsion driven rod 98, moment of torsion driven rod 98 drives swivel arm 77 again and rotates corresponding angle with the center of displacement transducer 10, when swivel arm 77 clockwise and inhour rotate to an angle and make circuit turn-on (can regulate the conducting angle as the case may be), but positive-negative polarity is opposite.The vibration of device is converted into the analog voltage signal of corresponding polarity by associated mechanisms, connecting link 97, fulcrum 102, moment of torsion driven rod 98, carbon film conductive contact blade group (87,88,92,102), promptly displacement transducer 10 is according to the big or small forward analog voltage signal that is complementary of exporting of positive-displacement of the associated mechanisms anomaly weighing apparatus position of device when the associated mechanisms of device vibrates downwards, and displacement transducer 10 is exported the inverse analog voltage signal that is complementary according to the associated mechanisms of device apart from the reverse displacement size of equilibrium position when the associated mechanisms of device upwards vibrates.
