Ultrasonic Frequency Detection Structure for Ultrasonic Biological Treatment

technical field

The invention relates to an ultrasonic frequency detection structure of an execution terminal for ultrasonic biological treatment operation.

Background technique

The processing rate of ultrasonic waves on objects is highly correlated with ultrasonic frequency, and the processing efficiency varies greatly with different ultrasonic frequencies; moreover, the type of biological cells to be processed is highly correlated with ultrasonic frequency, and different biological cells are highly sensitive to ultrasonic waves of different frequencies. Not the same. This has caused the blindness of the initial ultrasonic frequency determination in the existing ultrasonic biological treatment method, and further, the additional ultrasonic frequency analysis and determination form dependence. The actual working process is: using the processing conditions of a certain biological cell at different frequencies, performing cross-band comparison, analysis and determination, and obtaining relevant data; in future work, continue to use the data of the specific object to empirically determine the appropriate ultrasonic frequency. This is a customary practice. In essence, such a method cannot guarantee that the working ultrasonic frequency is the optimal frequency for the object, nor can it perform precise and fine frequency adjustments for different objects, and the accumulated experience is not the best process; in addition, the The method not only consumes a lot of manpower, financial resources and material resources in the initial stage, but also often requires observation, adjustment and maintenance during the use period.

In view of this, it is necessary to develop a new high-efficiency strategy, so that the work of ultrasonic biological treatment will no longer follow the inefficient method of first comparing the frequency bands, analyzing and determining the ultrasonic frequency, and then empirically determining the required frequency. Instead, it will determine the required frequency. The process of frequency is carried out efficiently and automatically to the greatest extent. An efficient solution to this kind of problem is the integrated structure of frequency search and control of ultrasonic bioprocessing, and the most difficult problem of the integrated structure is the wide-band transduction matching technology, that is, as the search frequency changes, in several broadband frequency bands with different center frequencies How to realize the frequency band search transduction matching of the resonant network between the vibrating plate and the driving power supply. For such a complex matching structure, control is a more complicated and unavoidable problem, and obtaining frequency feedback signal is the primary problem of control. Furthermore, the implementation of ultrasonic frequency detection of the terminal has become a key and urgent problem to be solved. Different from the frequency detection of single-frequency ultrasonic execution terminal, the frequency detection of ultrasonic bioprocessing frequency search and control integrated system needs to be carried out on the dynamic execution terminal. Therefore, it is necessary to develop an unconventional detection structure suitable for this constantly switching process system.

The end with the same name and the end with the opposite end of the current detection coil W _i serve as the current signal terminal T _i and the current signal start terminal T _i0 respectively, and are connected to the detection signal processing circuit SP.

The voltage signal terminal T _v is connected to pin 7 of the phase detector chip IC through the voltage signal coupling resistor R _v , and the terminal T _v0 at the beginning of the voltage signal is grounded; the voltage signal reverse phase limiting diode D _v1 and the voltage signal positive phase limiting diode D _v2 constitutes an anti-parallel branch, which is connected between pin 7 of the phase detector chip IC and the ground.
