Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a capsule device and a starting method thereof. Background Art

[0002] In the existing capsule device, due to its own independence, the integrity and sealing of the shell, the method of starting the capsule device is usually through a non-contact switch, such as a photoelectric switch, a magnetic switch, etc. These switches require the use of a designated auxiliary tool outside the capsule device to work properly. Therefore, there is currently a technical solution that detects the acceleration of the capsule device to open it, but it is easy to use the acceleration generated by vibration during transportation and handling as a start signal, which will cause the device to be opened by mistake. Summary of the invention

[0003] The object of the present invention is to provide a capsule device and a method for starting the capsule device.

[0004] The present invention provides a method for starting a capsule device, the method comprising:

[0005] Detecting and judging the motion state of the capsule device, when the capsule device meets the motion condition, the driving power supply supplies power to the light detection system of the capsule device,

[0006] Detecting the light intensity of the environment in which the capsule device is located, and setting a start gesture for the capsule device according to the light intensity, wherein the weaker the light intensity, the more complex the required start gesture;

[0007] The motion state of the capsule device is detected again, and when it is detected that the motion trajectory of the capsule device corresponds to the start gesture, the driving power supply supplies power to the working system of the capsule device.

[0008] As a further improvement of the present invention, the detecting of the light intensity of the environment in which the capsule device is located specifically includes:

[0009] The photoelectric element in the capsule device is controlled to detect the ambient light intensity, and the light intensity is detected according to the voltage converted from the current output by the photoelectric element.

[0010] As a further improvement of the present invention, the step of setting the startup gesture of the capsule device according to the light intensity specifically includes:

[0011] When the light intensity is greater than a preset light intensity threshold, setting the start gesture of the capsule device to a first start gesture;

[0012] When the light intensity is less than a preset light intensity threshold, the start gesture of the capsule device is set to a second start gesture, and the complexity of the second start gesture is greater than that of the first start gesture.

[0013] As a further improvement of the present invention, the step of setting the startup gesture of the capsule device according to the light intensity specifically includes:

[0014] The capsule device is preset with a plurality of light intensity intervals, calculates the light intensity interval in which the current light intensity is located, and configures the capsule device to a start gesture corresponding to the light intensity interval.

[0015] As a further improvement of the present invention, the detection determines the motion state of the capsule device, and when the capsule device meets the motion condition, the driving power supply supplies power to the light detection system of the capsule device, specifically including:

[0016] The acceleration of the capsule device is detected and determined. When the acceleration of the capsule device reaches a start threshold, a driving power supply supplies power to the light detection system of the capsule device.

[0017] As a further improvement of the present invention, the detecting and determining the acceleration of the capsule device specifically includes:

[0018] The acceleration sensor of the capsule device is kept powered, and the acceleration sensor is controlled to detect and determine the acceleration of the capsule device at a first detection frequency.

[0019] As a further improvement of the present invention, the re-detection and determination of the motion state of the capsule device specifically includes:

[0021] The acceleration sensor is controlled to continuously detect the acceleration value to determine the gesture action applied to the capsule device.

[0022] As a further improvement of the present invention, the steps are also included:

[0023] When the capsule device does not detect the application of a start gesture within a preset time period after starting the detection of the start gesture, the light detection system is stopped from being powered, and only the acceleration sensor is kept powered.

[0024] The present invention also provides a capsule device, including a capsule shell and a power supply, a vibration unit, and a circuit board located in the capsule shell. The capsule shell includes a control unit, a power start-up module, and an acceleration sensor arranged on the circuit board. The control unit includes a memory and a processor.

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 2 It is a schematic diagram of the steps of the method for starting a capsule device in one embodiment of the present invention. DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in combination with the specific implementation methods of the present invention and the corresponding drawings. Obviously, the described implementation methods are only part of the implementation methods of the present invention, not all implementation methods. Based on the implementation methods of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] This embodiment provides a capsule device and a method for starting the capsule device. The capsule device may be a capsule endoscope or a vibrating capsule, etc. This embodiment uses a vibrating capsule as an example to illustrate the structure of the capsule device and its method for starting the capsule device. Since the capsule device needs to be swallowed into the human body for use, the capsule device needs to remain sealed. The method for starting the capsule device provided in this embodiment does not require the aid of an external device, is easy to use, and can significantly reduce the probability of misstarting the capsule device in abnormal use scenarios such as transportation, and can overcome the problem of being unable to start in a dark environment when a single photoelectric element is used as a switch device.

[0032] like Figure 1As shown, the vibration capsule includes a capsule shell 1 and a power supply 2, a working unit 3, and a circuit board 4 located in the capsule shell 1.

[0033] The end of one side of the capsule shell 1 is transparent, and a control unit 5, a power start module 6, an acceleration sensor 7 and a photoelectric element 8 are arranged on a circuit board 4.

[0034] The power startup module 6 is configured to control the power supply 2 to supply power to the working unit 3 according to the signal input by the acceleration sensor 7 .

[0035] The photoelectric element 8 is arranged on the transparent side of the circuit board 4 facing the shell, and is used to receive light from the outside that shines into the capsule, sense the intensity of the light from the outside, and convert the light intensity into a corresponding electrical signal through the photoelectric effect.

[0036] The acceleration sensor 7 is a three-axis acceleration sensor, which is always in a powered-on working state to detect the motion state of the capsule device. The three-axis acceleration sensor 7 used is a low-power sensor, so that the power consumption of the continuous powered-on operation can be reduced. In other embodiments of the present invention, a gyroscope or other device can also be used to detect the motion state of the capsule device.

[0037] When the capsule device is a capsule endoscope, in addition to the conventional structure of the capsule endoscope, it is also provided with a photoelectric element 8 for detecting light intensity.

[0038] like Figure 2 As shown, the capsule device startup method includes:

[0039] S1: Detect and determine the motion state of the capsule device. When the capsule device meets the motion conditions, the driving power supply 2 supplies power to the light detection system of the capsule device.

[0040] S2: Detect the light intensity of the environment where the capsule device is located, and set the startup gesture of the capsule device according to the light intensity. When the light intensity is weaker, the required startup gesture is more complex.

[0041] S3: Detect and determine the motion state of the capsule device again. When it is detected that the motion trajectory of the capsule device corresponds to the start gesture, the driving power supply 2 supplies power to the working system of the capsule device.

[0042] Specifically, in step S1, it specifically includes:

[0043] The acceleration of the capsule device is detected and determined. When the acceleration of the capsule device reaches a start threshold, the driving power supply 2 supplies power to the light detection system of the capsule device.

[0044] The acceleration of the capsule device is continuously detected by the acceleration sensor 7 arranged in the capsule device. When the acceleration of the capsule device reaches the start threshold, it can be determined that the capsule device may be taken out for use. Since the capsule device may also generate acceleration during processes such as vehicle transportation and handling, thereby causing misjudgment, further judgment is required through the light detection system.

[0045] Further, while the acceleration sensor 7 of the capsule device is kept powered, the acceleration sensor 7 is controlled to detect and determine the acceleration of the capsule device at a first detection frequency.

[0046] The first detection frequency is a relatively low detection frequency, and can be set according to the power of the power source 2 used and the service life of the capsule device to ensure that the acceleration sensor 7 consumes less power during the continuous detection process.

[0047] In step S2, it specifically includes:

[0048] The photoelectric element 8 in the control capsule device detects the ambient light intensity, and detects the light intensity according to the voltage converted from the current output by the photoelectric element.

[0049] Specifically, in this embodiment, the light intensity is divided into two intervals, light and dark, and step S2 includes:

[0050] S21a: When the light intensity is greater than a preset light intensity threshold, setting the start gesture of the capsule device to a first start gesture.

[0051] S22a: When the light intensity is less than a preset light intensity threshold, setting the start gesture of the capsule device to a second start gesture, where the complexity of the second start gesture is greater than that of the first start gesture.

[0052] When it is detected that it is in a dark environment, there is a high possibility that the capsule device is still in the unopened packaging bag. The acceleration generated by the capsule device at this time is the acceleration generated by unexpected situations such as vibration during transportation and handling. Therefore, the capsule device is configured to enable more complex startup gestures, such as multiple consecutive shaking or circling to start the working system of the capsule device. At this time, the possibility of accidental startup of the capsule device can be greatly reduced, thereby avoiding the capsule device from running out of power due to accidental startup.

[0053] Furthermore, when the capsule device is in a dark environment, a start gesture is still set for the capsule device, which can avoid the situation where the user is in a dark environment and cannot start the capsule device when the photoelectric element 8 is used alone as a start switch, thereby improving the user experience.

[0054] When it is detected that the device is in a bright environment, there is a high possibility that the capsule device has been unpacked and taken out for use. At this time, a relatively simple startup gesture is configured for the capsule device, such as shaking it to start the capsule device. At this time, the amount of user operation required is small, and the recognition success rate is high, which can significantly improve the user experience.

[0055] After the capsule device is configured with a corresponding activation gesture, the capsule device can remind the user of the currently required activation gesture through an indicator light or an audio device.

[0056] In some other embodiments of the present invention, multiple illumination intensity intervals may also be set, and in this case, step S2 includes:

[0057] The capsule device is preset with multiple light intensity intervals, calculates the light intensity interval in which the current light intensity is located, and configures the capsule device to a start gesture corresponding to the light intensity interval.

[0058] Further adding multiple brightness ranges on the basis of the two brightness ranges of light and dark can further improve the accuracy of the capsule device in detecting the usage environment, adapt to different lighting conditions, and thus improve the judgment accuracy.

[0059] Specifically, in step S3, it includes:

[0060] Controlling the acceleration sensor 7 to detect the acceleration of the capsule device at a second detection frequency, where the second detection frequency is greater than the first detection frequency;

[0061] The acceleration sensor 7 is controlled to continuously detect the acceleration value to determine the gesture action applied to the capsule device.

[0062] In step S3, a second detection frequency with a higher detection frequency is enabled to improve the detection of the gesture action applied by the user to the capsule device, thereby improving the success rate of the detection.

[0063] Furthermore, after configuring the startup gesture, the following steps are also included:

[0064] When no opening gesture is detected within a preset time period, the light detection system is powered off, and only the acceleration sensor 7 is powered on, thereby avoiding an increase in power consumption.

[0065] The capsule device startup method provided in this embodiment combines the detection of acceleration and light intensity to control the startup of the capsule device, and configures the startup gesture of the capsule device according to the light intensity. Therefore, the capsule device can be started without the help of an external device, which is convenient to use and can significantly reduce the probability of misstarting the capsule device in abnormal use scenarios such as transportation. At the same time, it can also overcome the problem that the capsule device cannot be started in a dark environment when a single photoelectric element is used as a switch device.

[0066] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
