Description
Technical field
The invention belongs to ultrasonic sensor technical field, be specifically related to a kind of ultrasonic sensor of band signal treating apparatus.
Background technology
Ultrasonic sensor is the sensor utilizing hyperacoustic characteristic and be developed into, and its ultrasound wave launched has certain frequency range, when producing the signal in this frequency range in external environment, can produce interference to the detection of ultrasonic sensor; In addition, owing to being detected object, as smooth object, corner etc., this is that ultrasound wave can produce mirror-reflection or multiple reflections at its body surface, and this is that the distance of ultrasonic sensor detection and real distance value can produce error, affects degree of accuracy.
Summary of the invention
The object of the invention is to overcome existing sensor affects its degree of accuracy problem due to external signal interference and reflection error.
For this reason, the invention provides a kind of ultrasonic sensor of band signal treating apparatus, comprise sensor probe, ultrasound wave emission port one end of described sensor probe is connected with signal processing apparatus, by signal connecting line UNICOM between described signal processing apparatus and sensor probe, described signal processing apparatus is made up of the ultrasound wave circle in housing and housing.
Described signal connecting line is shielding line.
Described housing is the horn-like cavity structure of cone.
Described housing adopts acoustical material to obtain.
Described ultrasound wave circle is multiple, and arranges at a certain angle.
The invention provides a kind of ultrasonic sensor of band signal treating apparatus, its advantage is: structure is simple, carries out anti-interference and reflection error pre-service to the signal that ultrasonic sensor spreads out of, and effectively improves the degree of accuracy that ultrasonic sensor detects.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is the structural representation of the ultrasonic sensor of band signal treating apparatus of the present invention.
Description of reference numerals: 1, sensor probe; 2, signal connecting line; 3, signal processing apparatus; 4, housing; 5, ultrasound wave circle.
Embodiment
Embodiment one:
The defect of its degree of accuracy is affected due to external signal interference and reflection error in order to overcome existing sensor, the invention provides a kind of ultrasonic sensor of band signal treating apparatus as shown in Figure 1, comprise sensor probe 1, ultrasound wave emission port one end of described sensor probe 1 is connected with signal processing apparatus 3, by signal connecting line 2 UNICOM between described signal processing apparatus 3 and sensor probe 1, described signal processing apparatus is made up of the ultrasound wave circle 5 in housing 4 and housing 4.
The sensor probe 1 of this ultrasonic sensor launches ultrasonic signal, and ultrasonic signal is sent in signal processing apparatus through signal connecting line 2 and carries out signal transacting, then is launched by the signal processed.Described signal connecting line 2 is shielding lines, shielding outer signals is to the interference of ultrasonic signal, the housing 4 of described signal processing apparatus 3 adopts acoustical material that noise can be avoided the interference of signal, described housing 4 is horn-like structure, increases the level angle of ultrasonic sensor, increases investigative range, reduce detection blind area, be provided with the multiple ultrasound wave circles 5 arranged at a certain angle in described housing 4, this structure can record multiple hyperacoustic rreturn value, therefrom filters out correct reading.
More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
