Description
Technical field
The utility model relates to sensor technical field, is specially a kind of intelligence sensor Processing Interface device.
Background technology
Vibratory string class principle is that elder generation's logical relative forceful electric power of moment is given coil; Coil produces magnetic field, thereby attracts the string wire vibration of steel material, is the moment forceful electric power before the coil; Thereby the magnetic field of string wire vibration sectioned coil and magnet; Coil produces periodic minute current with the string wire periodic vibration, and the vibration frequency of string wire is to follow the level of tightness of string wire that relation is arranged, and the slight change of promptly opening the distance generation of 2 on string can be embodied in the vibration period of string; The change of frequency of electric current just; So the collection of vibratory string series products is the cyclical variation of minute current and voltage, and this voltage can not embody the slight change of 2 on a string intuitively, promptly sensor can not embody stressed or deformation intuitively.Inductor and vibratory string class sensor are similar, and inductor mainly is the degree of depth difference that stretches into coil according to iron core, and the inductance value of whole winding is also different, promptly forms variable inductance to coil and iron core.Utilize electric capacity and 555 chips to form oscillatory circuit then, can directly export the numerical frequency signal.The voltage class mainly is divided into two types, and one type is single channel, and one type is 2 passages.Single pass mainly is the sensor of front end sensors direct voltage output; Electronic type osmometer for example; Front-end probe is the pressure transducer that adopts Freescale, and the function of this probe is the variation that the variation of pressure is converted to voltage, with the variation voltage linear variation of pressure.What the resistance class adopted is the half-bridge structure output circuit, bridge balance, and two ends do not have voltage.When wherein a certain resistance changes, the electric bridge out of trim, thus voltage output is arranged.Can calculate corresponding resistance change and corresponding line strain size according to the size of voltage.
We find through above-mentioned principle, and its output all is simulating signal, and will simulating signal be changed into discernible physical quantity, also need analog quantity and calibration value be calculated, and is converted into data intuitively.Different sensor, algorithm model is different.In the traditional sensors structure, Signal Processing and calculating are accomplished by vasculum or upper layer software (applications), and the shortcoming of this series products mainly is: a little less than the original signal, can't transmit at a distance, vasculum is distributed in the point of monitoring rock and soil engineering with regard to corresponding increase; The corresponding complicacy of the circuit of vasculum, the corresponding increase of vasculum appearance structure; Data can not historicly be preserved, and recoverability is poor; Wiring is complicated, and all necessary independent cable of each sensor is to vasculum.
