Detailed Implementation

[0042] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0043] One embodiment of the present invention provides a data transmission method and apparatus for a capsule system that fully records the operation of a capsule endoscope in the real world, and the recording can be used for product problem analysis or functional improvement.

[0044] The capsule system 1000 of this embodiment includes a capsule endoscope 100 and a recorder 200. The capsule endoscope 100 can move within the digestive tract of a human or animal to the area of ​​interest. The capsule endoscope 100 can also take pictures and measure distances of the area of ​​interest using a camera, and then transmit the captured images and other data externally. The recorder 200 is used externally to acquire images transmitted by the capsule endoscope 100. The recorder 200 can be installed inside an examination garment worn by the user.

[0045] Additionally, the capsule system 1000 may include PC software and a magnetic control device. The PC software interacts with the recorder 200, controlling the operation of the recorder 200 and transmitting signals and data with it. The magnetic control device controls the movement of the capsule endoscope 100 within the digestive tract externally.

[0046] In this embodiment, the data transmission method of the capsule system 1000 is described using the movement of the capsule endoscope 100 in the digestive tract as an example.

[0047] The following is combined Figures 1-6 This invention describes a data transmission method for a capsule system 1000 provided in one embodiment.

[0048] The data transmission method in this embodiment is described in detail. Figure 1 The flowchart illustrates how, through the data transmission method of the capsule system 1000 in this embodiment, a complete set of medical record information can ultimately be obtained, such as... Figure 4 As shown. This case information consists of multiple sessions, each including one session between the capsule endoscope 100 and the recorder 200. Each session may or may not include images acquired by the capsule endoscope 100 at one time. The number of images acquired at one time can be n images acquired by n lenses. The flowchart of one session is as follows. Figure 2 As shown, the specific conversation content between the capsule endoscope 100 and the recorder 200 is as follows: Figure 3 As shown.

[0049] The following description uses a single session as an example to illustrate the data transmission method of the capsule system 1000. In this embodiment, the purpose of the session is primarily to acquire images obtained by the capsule endoscope 100. Furthermore, it can be combined with... Figure 2 and Figure 3 The following example illustrates the process of a session, which is the process of obtaining log records based on multiple steps.

[0050] Although this application provides method operation steps as shown in the following embodiments or flowcharts, the execution order of steps in which there is no logically necessary causal relationship, based on conventional or non-inventive effort, is not limited to the execution order provided in the embodiments of this application. For example, step S40 may be skipped after step S30, and step S50 may be executed directly.

[0051] Specifically, it includes the following steps:

[0052] Step S10: Record the request message based on the request information.

[0053] The request information is the information sent by the capsule endoscope 100 to the recorder 200, such as... Figure 3 As shown, after the recorder 200 receives the request information, it means that the recorder 200 and the capsule endoscope 100 have successfully shaken hands, and the recorder 200 generates a request message.

[0054] Step S20: Record the instruction message based on the control instructions.

[0055] The control command is the instruction sent by the recorder 200 to the capsule endoscope 100, such as... Figure 3 As shown, after the recorder 200 shakes hands with the capsule endoscope 100, the recorder 200 sends a control command to control the capsule endoscope 100 to capture images. Alternatively, the control command can be other types of commands, which will be described in another embodiment below.

[0056] Step S30: record working information based on working data.

[0057] The working data is the data sent by the capsule endoscope 100 to the recorder 200, and the working data includes image data and capsule sensor data, and the working information includes image information based on the image data and the capsule sensor data. As shown in Figure 3 After the capsule endoscope 100 receives the control instruction of the recorder 200, the capsule endoscope 100 sends image data, which is the image of the digestive tract taken by the camera module 10 of the capsule endoscope 100. The image information is the information of the digestive tract image, such as resolution, compression type, compression quality, length of image data, etc. At the same time, the capsule endoscope 100 also combines the data collected by the other sensor module 20 except the camera module 10 and the working mode into the image data and transmits them together.

[0058] The other sensor module 20 can include a gyroscope, a magnetic sensor, a temperature sensor, etc., and the capsule sensor data includes at least one of acceleration, angular velocity, magnetic field strength, pressure, temperature, voltage, transmission rate, and sampling mode of the capsule endoscope 100. These capsule sensor data reflect the environment and running state of the capsule endoscope 100 in the digestive tract when taking the current digestive tract image.

[0059] In addition, step S30 also includes the following steps:

[0060] Step S31: check the data integrity of the working information;

[0061] Step S311: if the data is complete, the image information is the image feature data of the image data, and the image data is stored in the storage module 60;

[0062] Step S312: if the data is not complete, the image information is a preset image error information.

[0063] The working information is the data sent by the capsule endoscope 100 and obtained by the recorder 200, and the data may have the problem of packet loss. The completeness judged in step S31 can be that when the packet loss rate is greater than a certain proportion, the data is judged to be incomplete, and when the packet loss rate is less than a certain value, the data is judged to be complete.

[0064] When the data is complete, the image feature data of the image data, that is, the content to be recorded into the log record later, can be the size, resolution, etc. of the image; when the data is not complete, the image information is marked as a preset image error information, such as FALSE.

[0065] Step S40: Load the running status of the recorder 200 itself.

[0066] In the subsequent step S50, the log records include the operating status of the logger 200 itself.

[0067] The operating status includes antenna reception strength, antenna number of the antenna that received the working data, and reception time.

[0068] The recorder 200 can have multiple wireless antennas. The capsule endoscope 100 can acquire wireless signals from different wireless antennas at different locations in the digestive tract. The reception strength, antenna number, and reception time of the wireless antenna that received the working information in each session are recorded in the log, which can facilitate subsequent analysis and optimization.

[0069] Step S50: Generate log records, wherein the log records include the request message, the instruction message, and the work information.

[0070] In one embodiment, step S50 can be run simultaneously with steps S10 to S40 described above. After running step S10, a request message is obtained, and at this point, the request message becomes part of the log record. After running step S20, an instruction message is obtained, and at this point, the instruction message also becomes part of the log record. Then, after running steps S30 and S40, the work information and the operating status of the logger 200 itself, added sequentially, also become part of the log record. The formation of the log record is a gradually enriching process.

[0071] In another embodiment, steps S10 to S40 sequentially obtain request messages, instruction messages, work information, and the running status of the logger 200 itself. These data can be stored in a buffer area, and then in step S50, the data in the buffer area is aggregated to generate a log record.

[0072] Through the data transmission method described above, the following can be obtained: Figure 5 The log records shown include communication commands between the capsule endoscope 100 and the recorder 200, and SENSORS data acquired by other sensors besides the image sensor.

[0073] Steps S10 to S50 described above can all be completed within the cache module. Considering the log data volume of a single session and the I / O pressure, the cache module should be used as much as possible when its capacity is sufficient. The request messages, command messages, working information, and the logger 200's own operating status and log records are all initially stored in the cache module. Specifically:

[0074] Step S10 comprises recording the request message in the cache module.

[0075] Step S20 comprises recording the instruction message in the cache module.

[0076] Step S30 comprises recording the work information in the cache module.

[0077] Step S40 comprises recording the running state of the recorder 200 itself in the cache module.

[0078] Step S50 comprises saving the generated log record in the cache module.

[0079] Only when the above-mentioned method corresponds to a session that is about to be completed, the following steps are run:

[0080] Step S60: storing the log record to the storage module 60.

[0081] Step S70: the recorder sleeps.

[0082] In the above-mentioned method, only the last log record and image data are stored in the storage module 60, and the rest of the previous data are stored in the cache module, and then the recorder sleeps. That is, the storage time of the log is placed after the end of the session and before the recorder sleeps, the cache module is used as much as possible, and the number of I / O is reduced. Figure 2

[0083] In addition, when a session is completed, the temporary data in the cache module is emptied.

[0084] After the above-mentioned session is completed, a log record in session 1 or session 2 as shown in Figure 4 is obtained, and the image corresponding to the session is combined, that is, the entire content of session 1, if the verification process in step S31 is incomplete, the session does not contain image data, and the image information is a preset image error information.

[0085] After multiple sessions are completed, multiple sessions form a complete case information.

[0086] The case information obtained after the above-mentioned data transmission method is run can be uploaded to a PC or a server. In the transmission process, the authorization, encryption and decryption of the data are involved, and only after authorization can the data be read. The data on the PC can also be backed up in an object storage system, which can provide high throughput, low delay data access service and support concurrency, and is very suitable for the business scenario of client uploading / downloading data.

[0087] ​In another embodiment, which is distinguished from the above embodiment, the embodiment does not include the step of acquiring images in the session, the embodiment can be that the recorder 200 only controls the registers of the capsule endoscope 100, or only acquires hardware information of the capsule endoscope 100, and a log record as shown in Figure 6 may be obtained, specifically including the following steps:

[0088] recording a request message based on request information, wherein the request information is information sent by the capsule endoscope 100 to the recorder 200;

[0089] recording an instruction message based on a control instruction, wherein the control instruction is an instruction sent by the recorder 200 to the capsule endoscope 100;

[0090] The recorder 200 generates a log record, wherein the log record includes the request message and the instruction message.

[0091] The specific implementation of these steps can be understood with reference to the above embodiment.

[0092] This embodiment can correspond to the session 3 in Figure 4 , the session 3 only includes a log record and does not include image data.
