Description

Technical Field

[0001] The present application relates to the technical field of device management, and in particular, to a battery-powered device and a reset method for a battery-powered device. Background Art

[0002] The capsule endoscope moves in the body with the peristalsis of the digestive tract and the action of gravity, and takes pictures for the diagnosis of digestive tract diseases. The capsule endoscope consists of a microprocessor, an image sensor and a radio frequency device. The capsule endoscope is powered by an internal battery. When a failure or poor communication occurs, the microprocessor sends a reset signal to reset the devices of the capsule endoscope to restore normal functions.

[0003] In digital circuits, system crashes and program runaway are likely to occur. Currently, the technology usually uses an on-chip or off-chip watchdog chip built in the microprocessor to implement the reset function. That is, the microprocessor periodically sends data or pulses to the watchdog. If the microprocessor fails and the watchdog does not receive data or pulses for a period of time, it will send a reset signal to reset the microprocessor or the entire system. That is, to power on the microprocessor or the entire system again to make the system return to the normal state.

[0004] For a capsule endoscope or a similar device powered by a battery, powering on the system again will generate a large instantaneous current. Taking the capsule endoscope as an example, it generally consists of a microprocessor, an image sensor and a radio frequency device. Because when performing a reset operation, all registers of the devices will restore their default values, and some logics and power supplies will restart, which will cause a relatively large instantaneous current to appear. And the relatively large instantaneous current may cause damage to the components in the device, resulting in the device being unable to work properly.

[0005] It can be seen that how to improve the reliability of device reset is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0030] The terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above drawings are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may include steps or units not listed.

[0031] To enable those skilled in the art to better understand the solution of the present application, the following will further describe the present application in detail with reference to the drawings and specific embodiments.

[0032] Next, a battery-powered device provided by an embodiment of the present application will be introduced in detail. Figure 1 As shown in the structural schematic diagram of a battery-powered device provided by an embodiment of the present application, it includes a microcontroller 11, a power supply battery 12, and multiple functional components 13.

[0033] The types of the functional components 13 can be diverse. In the embodiment of the present application, other components that need to be powered except the microcontroller 11 are collectively referred to as the functional components 13. Figure 1 In this example, there are three functional components, namely functional component A, functional component B, and functional component C. In actual applications, the number of the functional components 13 can be one or multiple, and the number of the functional components 13 is not limited.

[0034] The power supply battery 12 is connected to the microcontroller 11 and is used to provide a power supply to the microcontroller 11.

[0035] Considering that in actual applications, when the battery-powered device performs a reset operation, all components will generate a large instantaneous current due to instantaneous startup. The large instantaneous current may cause damage to the components, thereby affecting their normal operation. Therefore, in the embodiment of the present application, the microcontroller 11 can control the power supply methods of the respective functional components 13. To avoid a large instantaneous current caused by simultaneous power supply, the microcontroller 11 can be respectively connected to multiple functional components 13, and in the case of receiving a reset signal, supply power to the multiple functional components 13 in sequence according to the set component startup method.

[0036] The time taken for each functional component to complete power-on and restart varies. Therefore, the time taken for each functional component to power on and restart can be pre-tested. Based on the time taken for each functional component to power on and restart, the time interval between power-on startups of different functional components can be determined.

[0037] The component startup method can include the component startup sequence and the component startup time interval.

[0038] To implement the power-on control of all functional components 13 by the microcontroller 11, multiple power management components can be built in the microcontroller 11; each power management component has a corresponding functional component 13 connected thereto.

[0039] The microcontroller 11 can control the on / off of the power management components corresponding to the respective functional components 13 according to the set component startup sequence and component startup time interval, so as to achieve sequential power supply to the multiple functional components 13.

[0040] Taking a battery-powered device as an example of a capsule endoscope, the functional components included in the capsule endoscope may include an image sensor, a radio frequency component, and a light source component. The microcontroller can be connected to the image sensor, the radio frequency component, and the light source component respectively.

[0041] Figure 2 FIG. is a schematic diagram of the connection relationship of the hardware devices of a capsule endoscope provided in an embodiment of the present application. Figure 2 In the figure, the power supply battery is directly connected to the microcontroller, and the microcontroller is respectively connected to the light source component, the image sensor, and the radio frequency component. When the capsule endoscope needs to be powered on and restarted, the power supply battery will directly supply power to the microcontroller. After the microcontroller completes its own restart, it can supply power to other components in sequence according to the set component startup sequence and component startup time interval.

[0042] For example, assume that the time taken for the image sensor to power on and restart is 10 milliseconds, the time taken for the radio frequency component to power on and restart is 15 milliseconds, and the time taken for the light source component to power on and restart is 8 milliseconds. In actual applications, these functional components can be started in sequence according to the image sensor, the radio frequency component, and the light source component. Correspondingly, when the microcontroller receives a reset signal, it can first control the power management component corresponding to the image sensor to be enabled, so that the link between the image sensor and the power supply battery is turned on. After waiting for 10 milliseconds, the microcontroller can then control the power management component corresponding to the radio frequency component to be enabled, so that the link between the radio frequency component and the power supply battery is turned on. After waiting for 15 milliseconds, the microcontroller can then control the power management component corresponding to the light source component to be enabled, so that the link between the light source component and the power supply battery is turned on. Thus, through the microcontroller, the sequential power supply of all functional components is completed. Since the functional components do not power on and restart simultaneously, almost no large instantaneous current is generated, improving the safety of the restart of the battery-powered device.

[0043] In order to facilitate the microcontroller 11 to control the on-off of the link between different functional components 13 and the power supply battery 12, the power management component can be in the form of a switch. Considering that in actual applications, different types of functional components 13 require different supply voltages, in order to provide appropriate voltages to each functional component 13, a voltage conversion component can be provided in the power management component.

[0044] Therefore, in the embodiment of the present application, the power management component may include a voltage conversion component and a switch component; the microcontroller 11 controls the on-off of the link between the power supply battery 12 and each functional component 13 through the switch component. The voltage conversion component is used to convert the voltage transmitted by the microcontroller 11 into a voltage matching the functional component 13 connected to the voltage conversion component.

[0045] In practical applications, in order to reduce the power consumption of battery-powered devices, the microcontroller 11 can supply power to the functional components 13 associated with the service requirements based on the current service requirements, and cut off the power supply to the functional components 13 that are not associated with the service requirements.

[0046] Taking a capsule endoscope as an example, assume that currently, it is necessary to rely on the image sensor to collect images without using the radio frequency component. At this time, the microcontroller 11 can control the connection between the power supply battery 12 and the image sensor, and cut off the connection between the radio frequency component and the power supply battery 12. At this time, the power supply battery 12 does not need to supply power to the radio frequency component, reducing the power consumption of the power supply battery 12. Correspondingly, when it is necessary to transmit data outward through the radio frequency component and no longer use the image sensor to collect images, the microcontroller 11 can control the connection between the power supply battery 12 and the radio frequency component, and cut off the connection between the image sensor and the power supply battery 12.

[0047] It can be seen from the above technical solution that the battery-powered device includes a microcontroller, a power supply battery, and multiple functional components; the power supply battery is connected to the microcontroller and is used to provide a power supply to the microcontroller; the microcontroller is respectively connected to the multiple functional components and is used to supply power to the multiple functional components in sequence according to the set component startup method when receiving a reset signal. In this technical solution, in the reset state, the power supply battery directly supplies power to the microcontroller, and the microcontroller can control the on / off of the link between the power supply battery and the functional components in sequence, so that each functional component can be powered in sequence, effectively avoiding the instantaneous large current generated by multiple components resetting simultaneously when the battery-powered device is reset, ensuring the smooth realization of the reset of the battery-powered device, and improving the reliability of the device reset.

[0048] Figure 3 The flowchart of a reset method for a battery-powered device provided by an embodiment of the present application includes:

[0049] S301: Receive a reset signal.

[0050] When the battery-powered device needs to be restarted, the reset function can be implemented through a watchdog chip built in or external to the microcontroller. The watchdog chip transmits a reset signal to the microcontroller.

[0051] The power supply battery is connected to the microcontroller and can directly supply power to the microcontroller during power-on reset.

[0052] S302: Supply power to multiple functional components in sequence according to the set component startup method.

[0053] In practical applications, when a battery-powered device performs a reset operation, all components will generate a large instantaneous current due to instantaneous startup. The large instantaneous current may cause damage to the components, thereby affecting their normal operation. Therefore, in the embodiments of the present application, the microcontroller can control the power supply modes of the functional components. To avoid a large instantaneous current caused by simultaneous power supply, the microcontroller can be respectively connected to multiple functional components, and in the case of receiving a reset signal, supply power to the multiple functional components sequentially according to the set component startup mode.

[0054] The time taken for each functional component to complete power-on and restart varies. Therefore, the time taken for each functional component to power on and restart can be pre-tested. Based on the time taken for each functional component to power on and restart, the time interval for power-on startup between different functional components can be determined.

[0055] The component startup mode can include the component startup sequence and the component startup time interval.

[0056] To enable the microcontroller to control the power-on management of all functional components, multiple power management components can be built into the microcontroller; each power management component has a corresponding functional component connected to it.

[0057] The microcontroller can control the on / off of the power management components corresponding to the respective functional components according to the set component startup sequence and component startup time interval, thereby achieving sequential power supply to multiple functional components.

[0058] To facilitate the microcontroller to control the on / off of the link between different functional components and the power supply battery, the power management component can be in the form of a switch. Considering that in practical applications, different types of functional components require different supply voltages, in order to provide appropriate voltages to the functional components, a voltage conversion component can be provided in the power management component.

[0059] Therefore, in the embodiments of the present application, the power management component can include a voltage conversion component and a switch component; the microcontroller controls the on / off of the link between the power supply battery and each functional component through the switch component. The voltage conversion component is used to convert the voltage transmitted by the microcontroller into a voltage that matches the functional component connected to the voltage conversion component.

[0060] In practical applications, to reduce the power consumption of the battery-powered device, the microcontroller can supply power to the functional components associated with the current service requirements based on the current service requirements, and cut off the power supply to the functional components not associated with the service requirements.

In this technical solution, in the reset state, the power supply battery directly supplies power to the microcontroller, and the microcontroller can sequentially control the on / off of the links between the power supply battery and the functional components, so that each functional component can be powered in sequence, effectively avoiding the instantaneous large current generated by the simultaneous reset of multiple components when the battery-powered device is reset, ensuring the smooth implementation of the reset of the battery-powered device, and improving the reliability of the device reset.
