Description
Technical Field
The invention relates to the technical field of ultrasonic detection, in particular to an ultrasonic detection system and method for muscle group movement information.
Background
The detection of physiological signals of the human or animal body is one of the methods commonly used in clinical practice. The most common method is to take various biological potentials of human or animal bodies through electrodes for detection, such as EMG signals, EEG signals, etc. Currently, man-machine interfaces are a relatively new area of bio-signal applications, such as for mechanical devices, prosthetics, and computer control and operation.
In the control of mechanical prosthetic hands, surface electromyographic signals are the most common input control signals. However, the surface electromyographic signals are susceptible to various noise disturbances, such as electrode deflection, muscle fatigue, perspiration secretion, and the like. Therefore, it is necessary to find a new sensing means that is efficient and free from these interferences. Among them, real-time detection of muscle dynamics by using ultrasound atlas is such a new method. In addition, the surface electromyographic signals often cannot reflect signals generated by muscle movement at a deeper position, and ultrasonic detection can make up for the deficiency.
Clinically, B-ultrasound is often used to examine changes in the internal tissues of the human body. However, more sensing probes are needed for obtaining B-mode ultrasound, more complicated and large-scale acquisition and processing equipment is needed, the cost is high, and the wearable simple equipment is not favorably manufactured, and the wearable simple equipment is not favorably integrated into a prosthetic cavity. The invention adopts the A-mode for signal detection, because the A-mode can effectively avoid the defects.
The boundary between muscle tissue and other tissue has obvious echo effect on ultrasonic signals, so that muscle activity information can be obtained by detecting the change of the fixed echo signals along with muscle contraction. Contraction of the muscle causes some of the stronger reflection points on the echo to shift in the time axis. This is the basic principle of A-mode ultrasound to detect changes in muscle morphology. The changes in muscle contraction are three-dimensional, however single-channel a-ultrasonography can only reflect changes in the morphology of the muscle in one particular direction. The design evenly distributes the ultrasonic sensors of multiple channels into a ring, so that the dynamic change of muscles can be detected from different angles on the cutting surface of one muscle.
Accordingly, those skilled in the art have endeavored to develop a low-cost, high-stability sensing device that can detect changes in muscle morphology.

Referring to fig. 1, the ultrasonic detection system 1 for muscle group movement information includes an ultrasonic sensor 11 and an ultrasonic signal processing device 12. In this embodiment, the ultrasound sensing system is suitable for a-mode ultrasound testing.
It should be noted that fig. 1 shows three ultrasonic sensors, but the technical solution is not limited thereto, and in practical applications, the number of the ultrasonic sensors used may be determined according to the detection requirement, and the ultrasonic signal processing device needs to provide ultrasonic channels matching with the number of the ultrasonic sensors. In order to solve the problems of the prior art, in the present embodiment, the number of the ultrasonic sensors is at least two.
Specifically, each of the ultrasonic sensors 11 is configured to receive an ultrasonic emission signal emitted by the ultrasonic signal processing device 12 to acquire an ultrasonic echo signal inside the body of the detected object, and feed the ultrasonic echo signal back to the ultrasonic signal processing device 12.
In practice, each ultrasonic sensor can be worn on the surface of the body of the detected object according to the requirement of ultrasonic detection. For example, when the limbs of the detected object are detected by ultrasound, the distribution mode of the plurality of ultrasound sensors may be an arm ring mode.

Referring to fig. 2, the ultrasonic signal processing apparatus 12 includes: an ultrasonic wave transmission signal generation unit 121, an ultrasonic echo signal processing unit 122, a high voltage transmission/reception converter 123, and a power manager 124.

The power manager 124 is configured to generate the operating voltages required by the ultrasonic wave transmission signal generating unit 121, the ultrasonic echo signal processing unit 122, and the high voltage transmitting/receiving converter 123.
In practice, each of the ultrasonic sensors 11 may be connected to an ultrasonic sensor head (not shown) through a data connection line (not shown), and the ultrasonic sensor head is configured to receive the ultrasonic wave transmission signal transmitted by the high voltage transmission/reception converter 123 and feed back the ultrasonic echo signal acquired by the ultrasonic sensor 11 to the high voltage transmission/reception converter 123.
More specifically, the ultrasonic wave emission signal generation unit 121 includes: a microcontroller 1211 and an ultrasonic pulse generator 1212.
The microcontroller 1211 is configured to generate a waveform required for transmitting the ultrasonic signal. The ultrasonic pulse generator 1212 is configured to generate an ultrasonic emission signal based on the waveform. It should be noted that, in this embodiment, all the ultrasonic sensors use the same ultrasonic emission signal generated by the ultrasonic emission signal generation unit. Therefore, no matter the ultrasonic signal processing device 12 generates the ultrasonic emission signal or receives and processes the ultrasonic echo signal, no complex processing is needed, the cost of ultrasonic detection of the muscle group movement information is saved, and the efficiency of ultrasonic detection of the muscle group movement information is improved.
The ultrasonic echo signal processing unit 122 includes: an ultrasonic signal amplifying and filtering unit 1221, an analog-to-digital converter 1222, an input-output buffer 1223, and a digital signal processor 1224.

The analog-to-digital converter 1222 is configured to convert the analog signal processed by the ultrasonic signal amplifying and filtering device 1221 into a digital signal. The input/output buffer 1223 is used for temporarily storing the ultrasonic echo signal from the analog-to-digital converter 1222. The digital signal processor 1224 is configured to process each ultrasonic echo signal output via the input/output buffer 1223 to detect a dynamic change of muscles inside a human body.
In this embodiment, the ultrasonic echo signal processing unit 122 processes the ultrasonic echo signals fed back from the respective ultrasonic sensors in a polling manner.
The ultrasonic signal processing device is divided into three stages aiming at the work of a single ultrasonic sensor, and the three stages are respectively as follows: the method comprises the steps of transmitting an ultrasonic wave transmitting signal, receiving an ultrasonic echo signal and transmitting and delaying the signal. Fig. 3 shows a timing diagram of signal transmission and reception when a single ultrasonic channel is operated. The transmitting time of the ultrasonic transmitting signal is 800 nanoseconds, the receiving duration of the ultrasonic echo signal is 50000 nanoseconds, and the signal transmission and delay are about 800 nanoseconds. Thus, the time taken for operation on a single channel (i.e., a single ultrasonic sensor) is less than 60000 nanoseconds. For the ultrasonic detection system of the muscle group movement information provided by the embodiment of the invention, when the signal transmission and delay stage of one channel is finished, the system automatically carries out the transmitting stage of the ultrasonic transmitting signal of the next channel, and so on.
With reference to fig. 2, in the above process, the ultrasonic echo signal processing unit 122 may temporarily store a part of the received ultrasonic echo signals through the input/output buffer 1223, and after all the ultrasonic sensors complete the return task of the ultrasonic echo signals, send all the ultrasonic echo signals to the digital signal processor 1224 for processing, and the digital signal processor 1224 is a main signal controller and may control communication with an upper computer.
The embodiment of the invention also provides an ultrasonic detection method of the muscle group movement information, which adopts the ultrasonic sensing system provided by the embodiment to carry out A-type ultrasonic detection on the dynamic change of the muscle inside the body of the detected object.
