Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a communication control method for a capsule endoscope system and the capsule endoscope system itself. Background Technology

[0002] Capsule endoscopy, a painless, anesthesia-free, disposable (no sterilization required) device for acquiring information about the internal human body, has been widely used in the examination of the digestive system. Powered by an internal battery, it uses an image sensor and control chip-based camera module to capture images of the digestive system. The images are then transmitted in real-time to an external device via a capsule antenna electrically connected to the RF module, by adjusting the transmission frequency of the capsule endoscope's radio frequency module. An external image receiving device receives and stores the images; the capsule endoscope itself does not store images or only caches a few images using a small internal storage device. After the examination, the images stored by the external image receiving device are exported all at once for the doctor's review.

[0003] For example, Chinese patent CN111281316A discloses a control method, system, electronic device, and readable storage medium for a capsule endoscope. The method includes: providing a working device comprising a capsule endoscope and an external recorder that cooperates with and controls the capsule endoscope; monitoring the received ambient power via the portable external recorder before or during the wireless transmission of the capsule endoscope, and / or monitoring the output power of the capsule endoscope when transmitting wireless data via the portable external recorder during the wireless transmission of the capsule endoscope; adjusting the working state of the working device according to the ambient power and / or the output power. This invention improves the wireless performance and working duration of the capsule endoscope by monitoring the power during the dormancy period before the capsule endoscope interacts with the external recorder and / or during the image interaction, thereby adjusting the working state of the capsule endoscope in real time.

[0004] However, in the aforementioned invention, the control and adjustment of the capsule endoscope's wireless transmission power requires receiving the wireless signal strength (Received Signal Strength Indication) monitoring results from a portable external recorder (mobile device). Therefore, there is a delay in adjusting the capsule endoscope's wireless transmission power, leading to the loss of collected in vivo data. Summary of the Invention

[0014] The capsule endoscope adjustment signal in the wireless communication response signal is acquired, wherein the capsule endoscope adjustment signal includes a frame rate adjustment signal, which is used to adjust the frame rate at which the capsule endoscope captures images inside the body.

[0015] As a further improvement to one embodiment of the present invention, in S3, "estimating the signal strength estimate of the acquired wireless communication response signal" specifically means:

[0016] Obtain the signal strength values ​​of the wireless communication response signals transmitted on multiple antennas of the external receiving device;

[0017] The maximum value among the multiple signal strength values ​​is obtained and used as the estimated signal strength value of the wireless communication response signal.

[0018] As a further improvement to one embodiment of the present invention, the process of "determining whether the aforementioned difference is less than or equal to a preset threshold" in S4 further includes:

[0019] When the aforementioned difference exceeds a preset threshold, the capsule endoscope stores the collected in vivo data in its storage medium.

Furthermore, this application utilizes bidirectional data transmission between the capsule endoscope and the external receiving device (the capsule endoscope transmits in vivo data to the external receiving device, and the external receiving device transmits some control information, such as the frame rate adjustment signal, to the capsule endoscope), eliminating the need for the external receiving device to send an additional wireless connection signal to the capsule endoscope, thus simplifying the control process of monitoring the signal strength of the wireless connection signal at the capsule endoscope.

[0040] Figure 2 This is a schematic diagram illustrating the process of acquiring and transmitting in vivo data in the storage medium using a capsule endoscope according to an embodiment of the present invention. Specific Implementation

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0043] To address the problem of data loss due to delays in wireless transmission power adjustment in capsule endoscopes, an embodiment of the present invention provides a communication control method for a capsule endoscope system.

[0044] like Figure 1 As shown, the communication control method of the capsule endoscope system in this embodiment includes:

[0045] S1: Control the capsule endoscope to send a wireless communication request signal to an external receiving device, and then collect data inside the body;

[0046] S2: When the external receiving device receives the aforementioned wireless communication request signal, it sends a wireless communication response signal to the capsule endoscope at a first power.

[0047] S3: The capsule endoscope acquires the aforementioned wireless communication response signal within a predetermined time after sending the wireless communication request signal, and estimates the signal strength of the acquired wireless communication response signal when it acquires the aforementioned wireless communication response signal.

[0048] S4: Obtain the difference between the aforementioned estimated signal strength value and the first power, and determine whether the aforementioned difference is less than or equal to a preset threshold. When it is less than or equal to the preset threshold, adjust the power of the capsule endoscope to the second power so that the capsule endoscope sends the collected in vivo data to the external receiving device.

[0049] Understandably, during the process of acquiring the wireless communication response signal within a predetermined time after sending the wireless communication request signal, the capsule endoscope may fail to acquire the aforementioned communication response signal. This situation indicates that there is some kind of obstacle in the communication between the external receiving device and the capsule. In order to prevent data loss, the capsule endoscope stores the collected in vivo data in its storage medium.

[0050] Furthermore, if the capsule endoscope receives the aforementioned wireless communication response signal within a predetermined time after sending the wireless communication request signal, it indicates that the capsule endoscope can connect and communicate with the external receiving device. When the capsule endoscope receives the aforementioned wireless communication response signal, it estimates the signal strength of the received wireless communication response signal. During this process, some adjustment signals for the capsule endoscope can be added to the wireless communication response signal, such as a frame rate adjustment signal, an automatic exposure control signal, etc. Among them, the frame rate adjustment signal is mainly used to adjust the frame rate of the capsule endoscope when taking pictures inside the body.

[0051] Of course, the wireless communication response signal may also contain other data, such as the first power value when the external receiving device sends the response signal, which is usually a fixed preset value.

[0052] Typically, an external receiving device may have multiple antennas, and the external receiving device transmits wireless communication response signals to the capsule endoscope through these multiple antennas. The capsule endoscope can process only one of them, for example, processing the first antenna that transmits the wireless response signal, or processing the antenna with the highest signal strength value. In this embodiment, the capsule endoscope selects to process the antenna with the highest signal strength value of the wireless response signal. Therefore, the process by which the capsule endoscope obtains the estimated signal strength value of the wireless communication response signal mainly includes:

[0053] Obtain the signal strength values ​​of the wireless communication response signals transmitted on multiple antennas of the external receiving device;

[0054] The maximum value among the multiple signal strength values ​​is obtained and used as the signal strength estimate of the wireless communication response signal. In this embodiment, the maximum value among the signal strength values ​​of the wireless communication response signals transmitted on multiple antennas is used as the signal strength estimate of the wireless communication response signal. There will be a difference between the signal strength estimate and the actual first power. This difference is usually considered to be the path loss value when transmitting data on the current channel.

[0055] Furthermore, there will be a difference between the estimated signal strength of the wireless communication response signal and the first power, which is the path loss value mentioned above, denoted as PL in this embodiment. Typically, a preset threshold is also set, defined as the upper limit of the loss, denoted as Pu in this embodiment. When the aforementioned path loss value is not greater than the preset threshold, i.e., PL ≤ Pu, in this case, the transmission power of the capsule endoscope can be adjusted from the current power to a second power, thereby enabling the transmission of the intra-body data collected by the capsule endoscope to an external receiving device.

[0056] However, when the aforementioned difference is greater than a preset threshold, that is, when PL > Pu, the wireless communication quality between the capsule endoscope and the external receiving device is poor. It is impossible to send the in vivo data collected by the capsule endoscope to the external receiving device by adjusting the transmission power of the capsule endoscope. In order to prevent data loss, the capsule endoscope will store the collected in vivo data in the storage medium of the capsule endoscope.

[0057] Furthermore, when PL ≤ Pu, the process of adjusting the transmission power of the capsule endoscope from the current power to the second power specifically includes:

[0058] The theoretical power setting required for the capsule endoscope can be calculated and defined as the preset power. Because this preset power is calculated, and the second power is adjusted by looking up a table based on it, the second power and the preset power may not be equal. For example, when setting the capsule endoscope, there are several selectable values ​​for the second power: -4dBm, 0dBm, 4dBm, 8dBm, and 12dBm. If a preset power is calculated to be 7dBm, then the most recent second power selected would be 8dBm.

[0059] In this embodiment, the aforementioned preset power can be denoted as Pct, which is the sum of the aforementioned path loss value PL and a desired power value. Here, the desired power value is denoted as Pe, and the value of Pe ranges from -70 to 50 dBm.

[0060] Therefore, the following formula can be obtained for calculating the preset power Pct:

[0061] Pct = Pe + PL.

[0062] Based on past data testing experience, the Pct value (unit: dBm) can be used to generate a power level lookup table through testing, which can be stored in the capsule endoscope's adjustment program. Then, based on the specific value of Pct, the required power level can be found, and the corresponding second power can be obtained. Thus, the power of the capsule endoscope can be quickly set from the current power to the second power according to the corresponding second power.

[0063] Alternatively, the power level Nrf can be obtained by quantizing the PL by setting a quantization value:

[0064] Nrf = floor(PL / △P)

[0065] Where ΔP is the quantization value, which is a defined value, for example, it can be defined as 10dB; the formula floor() indicates that the data is rounded down. Assuming 0 < PL < 80dB, then Nrf takes values ​​of 0, 1, 2, 3, 4, 5, 6, and 7, corresponding to 8 different power levels. The larger the PL, the higher the Nrf. By using Nrf and a pre-edited power level lookup table, the power of the capsule endoscope can be quickly adjusted from the current power to the second power. Understandably, the adjusted second power can be higher or lower than the previous power.

[0066] It should be noted that the second power determined in this cycle will be used by the capsule endoscope to send a wireless communication request signal to the external receiving device in the next cycle.

[0067] Furthermore, the process by which the capsule endoscope transmits the collected in vivo data to an external receiving device also includes:

[0068] The internal data stored in the storage medium is acquired and transmitted to an external receiving device. Here, the internal data in the storage medium includes both the internal data stored by the capsule endoscope when no communication response signal is received from the external receiving device, and the internal data stored when the difference between the estimated signal strength of the received wireless communication response signal and the first transmission power of the external receiving device is greater than a preset threshold, i.e., the internal data stored when PL > Pu.

[0069] Furthermore, when the capsule endoscope sends a wireless communication request signal to an external receiving device, this wireless communication request signal (denoted as Req) is sent at certain time intervals, referred to as the first preset time interval. Understandably, in this embodiment, S1 to S4 are performed cyclically at this first preset time interval. For ease of understanding, this first preset time interval is denoted as T. Understandably, the capsule endoscope's TSC (Transmission Sequence Control) module can calculate whether there is sufficient time to send temporary data based on the current data sampling rate (e.g., image frame rate) or the time interval T between two Reqs. The higher the current image capture frame rate (1 / T), the smaller T is, and vice versa.

[0070] Within the first preset time interval T between sending two Reqs, sending the Req itself requires a certain amount of time, and this sending time is difficult to measure. Therefore, it is necessary to calculate whether there is enough time to send the temporary data based on the first preset time interval T between the two Reqs. This mainly considers whether there is enough time to send the temporary data between the time after "the capsule endoscope sends a wireless communication request signal to the external receiving device" in S1 and the time between the completion of S4. In this embodiment, the time between the time after "the capsule endoscope sends a wireless communication request signal to the external receiving device" in S1 and the completion of S4 is called the first duration, and this first duration is denoted as ΔT.

[0071] The process of acquiring the internal data in the storage medium and sending it to an external receiving device mainly involves the following steps:

[0072] First, the surplus time within the first duration is obtained. This surplus time is mainly the idle time that exists after the capsule endoscope completes operations such as transmitting the in vivo data collected within the first duration to an external receiving device within the first duration.

[0073] Acquire M sets of data within the storage medium whose transmission time is less than or equal to the aforementioned surplus time;

[0074] Select any N sets of the in vivo data from the M sets and send them to an external receiving device so that the external receiving device can acquire the aforementioned in vivo data, wherein the total transmission time of the N sets of in vivo data does not exceed the surplus time. In this way, when the connection signal between the capsule endoscope and the external receiving device is relatively good during the first time period, after the capsule endoscope sends the in vivo data collected during the first time period to the external receiving device, it can also use the surplus time to send the in vivo data stored in its storage medium when the wireless communication quality is poor to the external receiving device.

[0075] Furthermore, such as Figure 2 As shown, taking the sequence of S1 to S4 completed by the capsule endoscope as the time axis, it can be understood that the time from "the capsule endoscope sending a wireless communication request signal to the external receiving device" in S1 to the completion of S4 is the first duration ΔT. Under the premise that it can send the collected in vivo data to the external receiving device after adjustment, the capsule endoscope will also perform the following operations within the first duration ΔT:

[0076] The wireless communication response signal is obtained within a predetermined time after the connection signal is sent. This predetermined time is denoted as Ti. Within the predetermined time Ti, the capsule endoscope can determine whether the path loss value PL of the external receiving device is less than or equal to the upper limit of loss value Pu.

[0077] The transmission power of the capsule endoscope is adjusted to a second power. Normally, the capsule endoscope's power is adjusted via its APC (Auto Power Control) unit. Adjusting the power improves data transmission quality, enabling the capsule endoscope to send internal data to an external receiving device. The APC control unit requires a certain adjustment time to adjust the power; this adjustment time is denoted as Tc.

[0078] The data in the body is collected within the first duration △T. The data collection device (DataCollection) of the capsule endoscope also requires a certain collection duration when collecting data, which is denoted as T0.

[0079] Then, the collected in vivo data is sent to an external receiving device. In this embodiment, the time it takes for the capsule endoscope to send the in vivo data to the external receiving device after collecting it is called the first transmission time. For ease of description, this first transmission time is denoted as T1.

[0080] In calculating whether the capsule endoscope has spare time within the first duration ΔT, in order to ensure the stability of data transmission, a system-reserved allowance duration should also be set for the system. In this embodiment, the system-reserved allowance duration is defined as a specific duration threshold, which is a fixed value denoted as Tth.

[0081] As described above, the surplus time is actually the difference between the first duration ΔT, the adjustment duration Tc of the APC control unit adjusting the power, the acquisition duration T0 of the data collection device acquiring in vivo data, the first transmission duration T1 for sending the acquired in vivo data to the external receiving device, the predetermined duration Ti, and the specific duration threshold Tth. Then, this surplus time is compared with the transmission duration of the in vivo data in the capsule endoscope's storage medium. For example, if there is a set of in vivo data in the storage medium with a transmission duration T2, and this transmission duration T2 is less than or equal to the aforementioned surplus time, the capsule endoscope can select this set of in vivo data and send it to the external receiving device. Of course, if the aforementioned surplus time is long enough, the capsule endoscope can select data with other transmission durations in the storage medium while selecting the in vivo data with the aforementioned transmission duration T2. ​​As long as the sum of the transmission durations of the selected in vivo data is less than or equal to the aforementioned surplus time, the capsule endoscope can send it to the external receiving device. When multiple pieces of in vivo data that can be sent to an external receiving device are stored in the storage medium of a capsule endoscope, they are usually sent sequentially according to the order in which they were acquired.

[0082] In summary, the embodiments of the present invention achieve the following technical effects:

[0083] 1. By directly monitoring the signal strength of the wireless communication response signal emitted by the external receiving device at the capsule endoscope, the process of capsule endoscope power adjustment and data transmission becomes autonomous and timely, avoiding the loss of in vivo data due to delays in capsule endoscope power adjustment; at the same time, this application utilizes bidirectional data transmission between the capsule endoscope and the external receiving device (the capsule endoscope transmits in vivo data to the external receiving device, and the external receiving device transmits some control information, such as the shooting frame rate adjustment signal, to the capsule endoscope), eliminating the need for the external receiving device to send an additional wireless connection signal to the capsule endoscope, thus simplifying the control process of monitoring the signal strength of the wireless connection signal at the capsule endoscope.

[0084] 2. When the communication quality between the capsule endoscope and the external receiving device is poor (i.e., the external receiving device cannot receive the wireless communication request signal sent by the capsule endoscope, or the external receiving device receives the wireless communication request signal sent by the capsule endoscope and sends a wireless communication response signal to the capsule endoscope, but the path loss value of the wireless communication response signal is greater than a preset threshold), the capsule endoscope can store the collected in vivo data in the storage medium of the capsule endoscope to prevent data loss.

[0085] 3. When the capsule endoscope has good communication quality with the external receiving device, that is, when the path loss value of the wireless communication response signal sent by the external receiving device is not greater than a preset threshold, the capsule endoscope can send the collected in vivo data to the external receiving device by adjusting the transmission power of the capsule endoscope. Furthermore, if the transmission time allows, the capsule endoscope can also send the in vivo data stored in the capsule endoscope's storage medium to the external receiving device.

[0086] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
