Description

technical field [0001] The invention relates to the field of ultrasonic scanning devices, in particular to a device and method capable of identifying an ultrasonic probe through a built-in graphic and text identification layer. Background technique [0002] Existing ultrasonic equipment mainly includes a host and an ultrasonic probe, wherein the ultrasonic probe is a conversion device for electric energy and sound energy. Taking medical ultrasound equipment as an example, see figure 1 , generally composed of base material 1a, single crystal layer 2a, matching layer 3a and lens layer 4a arranged in sequence, wherein the crystal layer 2a completes the conversion between acoustic energy and electric energy to generate and receive ultrasonic signals to realize ultrasonic scanning action, The matching layer 3a matches the acoustic impedance of the probe with the skin, which is conducive to sound wave propagation, and the lens layer 4a is used to converge or diverge sound waves; ...

AI Technical Summary

Problems solved by technology

When medical staff use the ultrasonic equipment that does not match the ultrasonic probe and the main body of the equipment, it will also affect the medical staff's judgment of the disease's condition, thereby affecting the treatment of patients, etc.

[0003] At present, most of the probe identification is resistance voltage division method or Microcontroller Unit (MCU) coding method; among them, the resistance voltage division method can achieve simple ID identification, and the combination of two resistors can design many different Voltage combination, and then use the voltage range to identify the ultrasonic probe. The resistance voltage division method can be copied as long as different probe types are obtained and the voltage range is measured. Therefore, the anti-theft function is not good; the MCU coding method communicates with the system through an algorithm. Although there is an algorithm to encrypt, with the continuous advancement of technology, it is now only necessary to use a logic analyzer to capture waveforms for analysis, and use imitation waveforms to crack

[0004] In addition, as a power output element, the ultrasonic probe is a consumable. As the working time increases, the parameters of the ultrasonic probe will drift, the performance will deteriorate or even fail, which will affect the performance of the ultrasonic equipment.
