The guide wire in the OCT probe affects image deformation for OCT imaging, so material detection of the guide wire is required. If the synchronicity of the transmission of the guide wires is not checked, a situation may arise: in general, the driving motor rotates at a constant speed, and when the rotation speed of the rear driving motor is not synchronous with the rotation speed of the guide wire at the detection end, the rotation speed of the guide wire at the detection end changes into a nonlinear variable-speed motion.

Based on the above, the embodiment of the invention discloses an OCT guide wire transmission synchronization detection method, device and system, wherein the obtained rotation data of the OCT guide wire and the drive data of a drive motor are compared to determine the difference between the obtained rotation data and the drive data, the corresponding synchronization result is finally determined, and when the detection is unqualified, prompt is timely performed, so that the quality of the finally selected OCT guide wire is improved.
Example one
Referring to fig. 1, fig. 1 is a schematic flow chart of an OCT guidewire transmission synchronization detection method according to an embodiment of the present invention. The execution main body of the method described in the embodiment of the present invention is an execution main body composed of software or/and hardware, and the execution main body can receive related information in a wired or/and wireless manner and can send a certain instruction. Of course, it may also have certain processing and storage functions. The execution body may control a plurality of devices, such as a remote physical server or a cloud server and related software, or may be a local host or a server and related software for performing related operations on a device installed somewhere. In some scenarios, multiple storage devices may also be controlled, which may be co-located with the device or located in a different location. As shown in fig. 1, the OCT-based guidewire transmission synchronicity detection method includes the following steps:
s101: receiving rotation data of the OCT guide wire detected by the rotary encoder;
the method mainly comprises the steps of acquiring rotation data of the OCT guide wire in the rotation process, and comparing the subsequent rotation change of the OCT guide wire and a driving motor; it is necessary to acquire the underlying OCT guidewire rotation data. Specifically, the detection can be performed by a rotary encoder, and the image acquisition is performed without using a high-speed camera in the embodiment of the present invention because the cost of the high-speed camera is too high, and if the high-speed camera is used, the high-speed camera needs to capture a corresponding guide wire image, and then the measurement of the high-speed rotation speed is performed according to the exposure time, which is relatively complex to implement, and the cost is high, so that the method is not convenient for popularization and application. In the embodiment of the invention, the rotary encoder is adopted for detection, so that the corresponding rotation data can be detected and acquired at lower cost.
The photoelectric rotary encoder can convert mechanical quantities such as angular displacement and angular speed of an output shaft into corresponding electric pulses through photoelectric conversion and output the electric pulses in digital quantity (REP). The output types of signals are divided into: voltage output, collector open circuit output, push-pull complementary output and long line drive output; the rotary encoder is a speed displacement sensor integrated with optical mechanical and electrical technology. The rotary encoder is composed of a photoelectric code disc with a shaft in the center, wherein annular through and dark scribed lines are arranged on the photoelectric code disc, and a photoelectric transmitting and receiving device reads the signals to obtain A, B, C, D which are formed by combining four groups of sine wave signals, each sine wave has a phase difference of 90 degrees (360 degrees relative to a cycle), C, D signals are reversed and are superposed on A, B two phases, and stable signals can be enhanced; and outputs a Z-phase pulse per revolution to represent a zero reference bit. A, B the phase difference between two phases is 90 degrees, so it can judge the positive rotation and reverse rotation of the coder by comparing the phase A with the phase B, and the zero reference position of the coder can be obtained by the zero pulse. The encoder code wheel is made of glass, metal and plastic, the glass code wheel is a very thin scribed line deposited on the glass, the thermal stability is good, the precision is high, the metal code wheel is not easy to break due to the fact that the metal directly passes through or does not pass through the scribed line, the precision is limited due to the fact that the metal has a certain thickness, the thermal stability is about an order of magnitude lower than that of the glass, the plastic code wheel is economical, the cost is low, and the precision, the thermal stability and the service life are all slightly poor. The resolution encoder provides how many open or dark lines per 360 degrees of rotation is referred to as resolution, also known as resolution indexing.
More preferably, in embodiments of the present invention the rotary encoder may be operated as an incremental rotary encoder, the incremental encoder shaft rotating with a corresponding phase output. The judgment of the rotation direction and the increase and decrease of the pulse number are realized by a rear direction judging circuit and a counter. The counting starting point can be set arbitrarily, and infinite accumulation and measurement of multiple circles can be realized. The Z signal, which gives one pulse per revolution, can also be used as a reference mechanical null. When the pulse is fixed and the resolution is needed to be improved, the original pulse number can be multiplied by two paths of signals with 90-degree phase difference A and B. The edge of one code disc is provided with slits (divided into transparent and non-transparent parts) with equal angles, and light sources and photosensitive elements are respectively arranged on two sides of the slit code disc. When the code wheel rotates with the working shaft, light and shade change of light is generated once every time the code wheel rotates through one gap, electric pulse output signals with certain amplitude and power can be obtained through shaping and amplification, and the number of pulses is equal to the number of the rotated gaps. The pulse signal is sent to a counter to count, and the rotating angle of the code disc can be known from the measured digital number. In order to determine the rotation direction, two sets of photoelectric conversion devices may be used. Their relative positions in space are related to ensure that the signals they produce differ in phase by 1/4 cycles.
S102: receiving detected driving data of the driving motor;
this step is mainly to acquire the driving data of the driving motor, that is, the rotation parameters of the corresponding driving motor need to be known. Because the data between the two needs to be compared, the corresponding driving data needs to be obtained, and the driving data can be the rotating speed of the driving motor.
As an optional implementation manner, in the first aspect of the embodiment of the present invention, the receiving the detected driving data of the driving motor includes:
receiving driving data of a driving motor detected by a motor encoder; or the like, or, alternatively,
drive data of the drive motor detected by the rotary encoder is received.
When detecting the speed of the driving motor, there are two ways, one is to directly detect the rotation speed of the driving motor through a motor encoder, and the other is to detect the rotation speed of the driving motor through a rotary encoder. When the rotary encoder is used for detecting the speed of the driving motor, the detection can be carried out in a mode of fixing an output shaft of the driving motor with the rotary encoder, or in a mode of fixing the output shaft of the driving motor with the rotary encoder through a rigid shaft; the purpose is to detect the drive data of the drive motor. In the embodiment of the invention, a mode of detecting by using a motor encoder is more preferable, so that the speed detection can be performed on the motor and the OCT guide wire, on one hand, the efficiency is improved, and on the other hand, the speed detection is performed in the same driving steering, and the detection result is more accurate.
S103: and analyzing and matching the rotation data and the driving data to obtain a corresponding synchronism result.
Since the corresponding rotation data is obtained in steps S101 and S102, the synchronization between the rotation data and the corresponding rotation data can be determined by directly matching the rotation data. That is, when the detected rotation data and the detected driving data are consistent, the result of the synchronization between the rotation data and the driving data is better, and if the speeds obtained by the rotation data and the driving data are inconsistent, the synchronization is poorer; specifically, the speed obtained from the drive data is generally greater than the speed obtained from the rotational data; therefore, when the specific numerical design is carried out, the judgment can be carried out according to the speed threshold value, namely, the poor synchronism of the speed threshold value is judged only when the difference value of the speed threshold value and the speed threshold value is larger than a set value; if the difference value of the two is smaller than the set value, the synchronism is judged to be better.
In addition to the above-described detection manner, it is also possible to express stability data of the angular velocity of the rotation data and the drive data, such as a standard deviation of the angular velocity. The smaller the standard deviation of the angular velocity, the more stable the rotation is, and the closer to the uniform motion is. Typically, the standard deviation of the angular velocity of the drive data is smaller than the standard deviation of the rotational data. We can decide as a result the ratio of the standard deviation of the rotation data to the standard deviation of the angular velocity of the drive data. The smaller the ratio, the better the synchronicity, and the larger the ratio, the worse the synchronicity.
As an optional implementation manner, in the first aspect of the embodiment of the present invention, after the performing the analytic matching on the rotation data and the driving data to obtain the corresponding synchronization result, the method further includes:
and if the synchronism result does not meet the preset requirement, judging that the detection result of the OCT guide wire is unqualified.
Whether the specific requirement is met or not can be set according to the actual situation, and because of the existence of errors in the detection process, a corresponding speed difference value can be set to judge the threshold value. And when the detection result does not meet the preset requirement, prompting that the detection result of the OCT guide wire is unqualified through voice or light.
As an optional implementation manner, in a first aspect of the embodiment of the present invention, fig. 2 is a schematic diagram of a specific process of data parsing and comparing disclosed in the embodiment of the present invention, as shown in fig. 2, the rotation data includes detected waveform data; the analyzing and matching of the rotation data and the driving data to obtain a corresponding synchronism result comprises the following steps:
s1031: analyzing the detection waveform data to obtain corresponding time data, wherein the time data is time data of the OCT guide wire rotating for multiple circles;
s1032: obtaining first angular velocity data and angular velocity stable data of the corresponding OCT guide wire according to the time data;
s1033: analyzing the driving data to obtain second angular velocity data of a corresponding driving motor;
s1034: and obtaining a corresponding synchronism result according to the first angular velocity data, the angular velocity stable data and the second angular velocity data.
Specifically, when the code wheel rotates for one circle, the number of pulses output by the optical sensor is certain, and the number of turns of the code wheel rotating in the certain time can be known by detecting the number of pulses received in the certain time, so that the speed is converted. For example, one code wheel rotates one cycle and outputs 100 pulses, and 500 pulses are received within 0.1s, which means that the code wheel rotates 5 cycles within 0.1s, i.e. the rotational speed of the code wheel is 50 r/s. Because the OCT guide wire is fixedly connected with the code wheel, the speed of the code wheel is also the speed of the OCT guide wire. Specifically, fig. 6 is a detected waveform image of the rotary encoder disclosed in the embodiment of the present invention, and as shown in fig. 6, the corresponding pulse detection data can be known; and finally calculating to obtain corresponding angular velocity data. In specific implementation, multiple circles of data need to be acquired, so that the accuracy and stability of the finally obtained data are higher.
According to the method for detecting the transmission synchronism of the OCT guide wire, the obtained rotation data of the OCT guide wire and the obtained driving data of the driving motor are compared to determine the difference between the obtained rotation data and the obtained driving data of the driving motor, the corresponding synchronism result is finally determined, when the detection is unqualified, prompt is timely carried out, and the quality of the OCT guide wire finally selected is improved.

In the implementation, there are two detection modes, one is to directly detect the rotation speed of the driving motor 1 through the motor encoder 8, and the other is to detect the rotation speed of the driving motor 1 through the rotary encoder 2. When the rotary encoder 2 is used for detecting the speed of the driving motor 1, the speed can be detected in a mode of fixing the output shaft of the driving motor 1 and the rotary encoder 2, and a mode of fixing the output shaft of the driving motor 1 and the rotary encoder 2 through the rigid shaft 7 can also be adopted; the purpose thereof is to detect the drive data of the drive motor 1.

When the pulse is fixed and the resolution is needed to be improved, the original pulse number can be multiplied by two paths of signals with 90-degree phase difference A and B. The edge of one code disc is provided with slits (divided into transparent and non-transparent parts) with equal angles, and light sources and photosensitive elements are respectively arranged on two sides of the slit code disc.
