Description
Technical field
The utility model relates to ultrasonic equipment, particularly has the ultrasonic transducer of quantitative amplitude reponse system.
Background technology
In existing ultrasonic wave emission system, most crucial parts are exactly driving power and transducer.Its operation principle is: driving power sends high-frequency high-power exciting current, drives transducer vibrations to launch ultrasonic wave.Transducer or directly launch ultrasonic wave, or promote ultrasonic transformer, emitting head, finally launch ultrasonic wave by emitting head.What determine ultrasonic wave emissive porwer is the amplitude of emitting head.The larger ultrasonic wave of amplitude is stronger.The electric current flowing through transducer is larger, or the driving voltage applied on the transducer is higher, and transducer vibrations is stronger, and amplitude is also larger.
When the overwhelming majority, such course of work is unidirectional.That is, driving power determines the size of transducer vibrational amplitude.But amplitude has much is on earth unclear, as amplitude controlling being also difficult to achieve one's goal in a default scope.Because existing transducer is passive parts, it does not have corresponding amplitude feedback mechanism, and all information is all indirectly.Also have and paste piezoelectric ceramics by face on the transducer, lead-in wire of burn-oning at the two poles of the earth of piezoelectric ceramics is linked into driving power.When transducer vibrations, piezoelectric ceramics can export the signal of telecommunication, and this piezoelectric ceramics is just equivalent to easy vibrating sensor.But such sensor is merely able to the vibration detecting transducer quantitatively.And because be wired, use very inconvenient.
If can whenever and wherever possible, direct quantitative measures the amplitude of transducer.And the information feed back of amplitude to driving power, allowing driving power make adjustment in time, is exactly so a huge progress for the control of ultrasonic equipment.Utilizing ultrasonic equipment to produce in the process of product, the quality stability of final products just greatly can be improved.

In the utility model, this ultrasonic wave emission system also comprises the non-contact radio-frequency generator matched with described amplitude detector internal wireless transmission circuit; This non-contact radio-frequency generator is connected to driving power by wire, and realizes power supply by driving power.
Utility model principles illustrated:
Core technology of the present utility model and innovation are: implant an amplitude detector in transducer inside.The module of the wireless receiving circuit matched is set in driving power inside.When ultrasonic system works (during transducer vibrations), amplitude detector detects the amplitude of transducer at any time, and sends wirelessly in real time.Driving power, according to the amplitude signal detected, is made adjustment to the power of drive circuit in real time.So just can ensure that the amplitude of transducer is in slave mode all the time, be unlikely to the best amplitude exceeding setting in advance, and the stable of this amplitude value can be guaranteed.
In the utility model, amplitude detector is made up of voltage generation sheet, rectification circuit, acceleration transducer, memory circuit, radio transmitter.Voltage generation sheet is piezoelectric ceramic devices, can produce electric charge when vibrating.Here it plays a battery, and this battery does not need charging, can not lose efficacy yet.As long as transducer produces to have vibrated and just can generate electricity, if transducer stops vibration just stopping generating.The galvanic current that rectification circuit becomes acceleration transducer to use the current commutates that voltage generation sheet produces.Acceleration transducer can the vibration of direct inductive transducer, and exports the corresponding signal of telecommunication.Memory circuit can store transducer initial parameter, coupling require, amplitude information, etc.Radio transmitter is transmitted to the amplitude signal received the wireless receiving circuit being positioned at driving power.Wireless receiving circuit by this signal transmission to control chip, to realize follow-up monitoring.
As another kind of alternative, amplitude detector is powered can without voltage generation sheet, but by the mode of radio frequency induction, at the inner generation current of detector.Namely driving power is powered to radio-frequency signal generator, produces radiofrequency signal.Radio-frequency signal generator is placed near the detector of transducer, in the scope of distance 1mm ~ 20mm.Radiofrequency signal is received by wireless transceiver circuit, converts the electric current of needs to.In other words, wireless transceiver circuit is operated in duplex state.On the one hand, it is a power supply.When radio-frequency signal generator exports radiofrequency signal, its is responded to and received RF signal, generation current.On the other hand, the amplitude signal that acceleration transducer exports, also by wireless transceiver circuit, can send out.
Having externally transmission amplitude signal and received RF signal is very ripe technology to realize the wireless transceiver circuit of the two-way function of powering, be widely used in the non-contact communicating device such as access card, attendance card, mess card, e-bank's card, highway non-parking charge card, there is the wireless transceiver circuit of two-way function the inside of these equipment.The i.e. function of existing power supply, has again the function of information exchange.
Memory circuit inside amplitude detector, can carry out exchanges data, the numbering storing transducer, condition code, original factory data with outside, and transmits coupling requirement to driving power.And the storage chip of driving power, except the data of receiving transducer, also need the matched data, the amplitude data that store transducer and the control data of inside.The latter is also very ripe, its technical connotation and access card similar.
Driving power, as the control unit of transducer (ultrasonic vibration system), after receiving the signal of acceleration transducer, by simple conversion, just can obtain the real-time amplitude of transducer.This amplitude is exactly the control foundation of driving power, can reach the object that we accurately control.On the other hand, the display screen can sending into driving power directly shows, and convenient operation person intuitively understands the ruuning situation of equipment.
