Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in figures 1-8, one kind according to the utility model embodiment is based on ultrasound re-opens detection device, packet
Control circuit is included, the control circuit is connected separately with power supply, ultrasonic wave transmitting circuit and ultrasonic wave and receives circuit, the ultrasound
Wave transmitting circuit is connected with transmitting probe, and the ultrasonic wave, which receives circuit connection, receiving transducer, and the control circuit is also connected with
There are calibration circuit and several indicator lights, the calibration circuit includes several keys.
In a specific embodiment of the utility model, the ultrasound wave transmitting circuit includes driving circuit and transformation
Device.
In a specific embodiment of the utility model, it includes Acquisition Circuit and processing electricity that the ultrasonic wave, which receives circuit,
Road, the processing circuit include filter circuit and amplifying circuit.
In a specific embodiment of the utility model, the control circuit includes MCU.
In a specific embodiment of the utility model, the control circuit is also connected with serial communication circuit.
In a specific embodiment of the utility model, the control circuit is also connected with light every output circuit.
