Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

This embodiment provides a capsule device and its activation method. The capsule device may be a capsule endoscope or a vibrating capsule. This embodiment uses a vibrating capsule as an example to describe the structure of the capsule device and its activation method. Since the capsule device needs to be swallowed into the human body for use, the capsule device needs to be kept in a sealed state. The method for starting the capsule device provided by this embodiment does not need external devices, is easy to use, can significantly reduce the probability of false start-up of the capsule device in abnormal use scenarios such as transportation, and can overcome the problem of using a single photoelectric element as a switch device. The problem of not being able to start in a dark environment.

As shown in Figure 1, the vibrating capsule includes a capsule housing 1 and a power supply 2, a working unit 3, and a circuit board 4 located in the capsule housing 1,

The end of one side of the capsule shell 1 is transparent, and the circuit board 4 is provided with a control unit 5 , a power starting module 6 , an acceleration sensor 7 and a photoelectric element 8 .

The power starting 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 .

The photoelectric element 8 is arranged on the transparent side of the circuit board 4 facing the shell, and is used to receive light irradiated into the capsule from the outside world, sense the light intensity of the outside world, and convert the light intensity into corresponding electrical signals through the photoelectric effect.

The acceleration sensor 7 is a three-axis acceleration sensor, which is always in the power-on working state to detect the motion state of the capsule device. The three-axis acceleration sensor 7 used is a low-power sensor, which can reduce its continuous power-on work. consume. In other embodiments of the present invention, equipment such as a gyroscope may also be used to detect the movement state of the capsule device.

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 the intensity of light.

As shown in Figure 2, the method for starting the capsule device includes:

S1: Detect and judge 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.

S2: Detect the light intensity of the environment where the capsule device is located, and set the start gesture of the capsule device according to the light intensity. When the light intensity is weaker, the required start gesture is more complicated.

S3: Detect and judge the motion state of the capsule device again, and when it is detected that the motion track of the capsule device corresponds to the start gesture, the driving power supply 2 supplies power to the working system of the capsule device.

Specifically, in step S1, it specifically includes:

The acceleration sensor 7 installed in the capsule device is used to continuously detect the acceleration of the capsule device. When the acceleration of the capsule device reaches the activation threshold, it can be judged that the capsule device may be taken out for use. In the same way, the capsule device may also be accelerated, resulting in misjudgment, so further judgment is required through the light detection system.

Further, during the process of maintaining the power supply of the acceleration sensor 7 of the capsule device, the acceleration sensor 7 is controlled to detect and judge the acceleration of the capsule device at the first detection frequency.

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

When it is detected that it is in a dark environment, it is more likely that the capsule device is still in an unopened packaging bag, and the acceleration generated by the capsule device at this time is the acceleration generated by accidents such as vibration during transportation and handling , so the capsule device is configured to enable more complex activation gestures, such as continuous shaking or turning in circles to open the working system of the capsule device, which can greatly reduce the false start of the capsule device, thereby avoiding the capsule device The battery is exhausted due to false start.

Moreover, in a dark environment, an activation gesture is still provided for the capsule device, which can avoid the situation that the user cannot activate the capsule device in a dark environment when the photoelectric element 8 is used alone as the activation switch, thereby increasing the user experience.

When it is detected that it is in a bright environment, it is more likely that the capsule device has been unpacked and taken out for use. At this time, configure a relatively simple activation gesture for the capsule device, such as shaking it to start the capsule device. At this time, the required The amount of user operations is small, and the recognition success rate is high, which can significantly improve user experience.

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.

The capsule device is preset with a plurality of light intensity intervals, calculates the light intensity interval where the current light intensity is located, and configures the capsule device as a start gesture corresponding to the light intensity interval.

Adding multiple brightness intervals on the basis of the two brightness intervals of light and dark can further improve the accuracy of the device's detection of the use environment and adapt to different lighting conditions, thereby improving the accuracy of judgment.

Specifically, in step S3, it includes:

Controlling the acceleration sensor 7 to detect the acceleration of the capsule device with a second detection frequency, the second detection frequency is greater than the first detection frequency;

The gesture action applied to the capsule device is determined by controlling the acceleration sensor 7 to continuously detect the acceleration value.

In step S3, enable the second detection frequency with a higher detection frequency to improve the detection of gestures applied by the user to the capsule device, thereby increasing the success rate of detection

Further, after configuring the start gesture, steps are also included:

When the opening gesture is not detected within the preset time period, the power supply to the detection system is stopped, and only the power supply to the acceleration sensor 7 continues to be maintained. Thereby avoiding increasing the consumption of electric energy.

The method for starting the capsule device provided in this embodiment simultaneously controls the opening of the capsule device by combining the detection of acceleration and light intensity, and configures the opening gesture of the capsule device according to the light intensity. Therefore, the capsule device can be activated without the help of an external device, which is convenient to use, and can significantly reduce the probability of false start-up of the capsule device in abnormal use scenarios such as the transportation process.
