Abstract

The invention discloses a control system for the blind area of ​​an ultrasonic transducer, which includes a double-sensor ultrasonic transducer, a controller and a reverse boost circuit; the double-sensor ultrasonic ring energy device includes an ultrasonic transmitting sensor, an ultrasonic receiving sensor, and an ultrasonic transmitting sensor Placed in the shell of the transmitting sensor, the ultrasonic receiving sensor is placed in the shell of the receiving sensor, and the shell of the transmitting sensor and the shell of the receiving sensor are connected together with a connecting piece; The boost circuit adjusts the driving voltage output to the ultrasonic transmitting sensor according to the reverse boost amplitude control signal; the reverse boost amplitude control signal is used to control the driving voltage of the ultrasonic transmitting sensor to change in the same direction as the distance to be measured. The invention has the advantages of small measurement blind area, wide measurement range and high detection precision.

Description

technical field [0001] The invention relates to the field of ultrasonic transducer control, in particular to a control system for the blind area of ​​the ultrasonic transducer. Background technique [0002] When using ultrasonic waves to measure the flow rate and object position, the ultrasonic transducer is excited by electric pulses to make it emit ultrasonic excitation signals. The ultrasonic signals propagate in the medium and are reflected back when they encounter different interfaces (such as the interface of water, oil and air). The returned ultrasonic signal is collectively referred to as the echo signal, and the flow or object position is measured by using the propagation time of the ultrasonic excitation signal and the ultrasonic echo signal. [0003] However, the working blind area of ​​the ultrasonic transducer is an obstacle to realize flow monitoring or position detection through ultrasonic waves. The electric pulse signal causes the energy conversion element ...
