In another aspect, the handheld device further includes a gyroscope, and the handheld device detects the usage status of the handheld device through the gyroscope. One way to detect the usage status of the handheld device is to detect the pointing direction of the handheld device through a gyroscope and determine whether the handheld device maintains the same pointing direction within a predetermined time. If the judgment result is yes, the handheld device is defined to be in an idle state, and if the judgment result is no, the handheld device is defined to be in a non-idle state, wherein the idle time is longer than the preset time.
In another aspect, if the handheld device is determined to be in an idle state and the idle state is maintained for more than a set idle time, the handheld device continuously sends out a reminding signal through the reminding unit to remind the user to charge the handheld device.
In another aspect, after the handheld device sends the reminding signal, the method further comprises the following steps: and judging whether the reminding unit is closed or not, if so, stopping sending the reminding signal, otherwise, continuously sending the reminding signal, and reminding a user to charge the handheld device in time.

Detailed Description
To explain the technical features of the present invention in detail, the following embodiments are described with reference to the accompanying drawings. In the present embodiment, a barcode scanner is taken as an example of the handheld device 10, please refer to fig. 1 first.
The barcode scanner may be provided with an arithmetic processing unit 11, a battery 12, a reminder device 13, and a gyroscope 14. The processor 11 is, for example, a microprocessor or other programmable general-purpose or special-purpose controller or the like. The arithmetic processing unit 11 is used for processing signals and is electrically connected with the gyroscope 14 and the reminding device 13. The battery 12 is a secondary battery, such as a lithium battery, for providing power to operate the various components within the hand-held device 10. The reminding device 13 is a speaker (speaker) in the embodiment, and the reminding device 13 can be controlled by the arithmetic processing unit 11 to emit a reminding signal in the form of sound. In addition, in order to achieve the scanning function of the barcode scanner, the barcode scanner further includes a scanner 15, a memory 16, and a display unit 17 (e.g., a touch screen), which are electrically connected to the arithmetic processing unit 11.
The following describes details of each step of the power reminding method, please refer to fig. 2 and fig. 3 in combination.
Step S1: and starting the steps. The handheld device 10 is turned on, so that the handheld device 10 is in a power-on and normal operation state.
Step S2 is performed after step S1. Step S2: the handheld device 10 detects and obtains the current charge of the battery 12. The handheld device 10 detects the charge of the battery 12 through a detection circuit.
After step S2, step S3 is performed, step S3: the processing unit 11 determines whether the detected power of the battery 12 is lower than a predetermined power, which can be manually set by a user, in this embodiment, the predetermined power is set to 50% of the maximum storable power of the battery 12. If the detected battery 12 is lower than the predetermined power level, step S4 is executed, and if the detected battery 12 is higher than the predetermined power level, step S2 is executed to continue detecting the power level of the battery 12.
Step S4: the specific steps of detecting the usage status of the handheld device 10 can be divided into steps S4.1 to S4.4 (see fig. 3). In step S4.1, the handheld device 10 detects the pointing direction of the handheld device 10 through the gyroscope 14. In a typical situation, if a user holds and uses the handheld device 10, the user may change the orientation of the handheld device 10 (e.g., flip the handheld device 10) according to the actual usage situation. Then, step S4.2 is executed to determine whether the handheld device 10 maintains the same pointing direction for a predetermined time. Specifically, the arithmetic processing unit 11 determines whether the pointing direction of the handheld device 10 is changed within a preset time (for example, 10 minutes) of the handheld device 10 according to the obtained pointing direction of the handheld device 10. If the handheld device 10 maintains the same orientation for a predetermined time, the handheld device 10 is defined to be in an idle state (step S4.3), and if the orientation of the handheld device 10 is changed for the predetermined time, the handheld device 10 is defined to be in a non-idle state (step S4.4).
After step S4, step S5 is performed. Step S5: the arithmetic processing unit 11 determines whether the handheld device 10 is in an idle state and exceeds an idle time. The length of the idle time can be set by the user, in this embodiment, the idle time is set to 30 minutes, if the handheld device 10 is in an idle state and exceeds 30 minutes, step S6 is entered, otherwise, step S4 is returned to.
Step S6: the arithmetic processing unit 11 controls the reminding device 13 to send out reminding signals. In this embodiment, the reminding device 13 is controlled to continuously make a sound, so as to remind the user to charge the handheld device 10.
Step S6 is followed by step S7. Step S7: judging whether the reminding device 13 is turned off by the user, if so, entering the step S8, and finishing all the steps; otherwise, returning to step S6, the reminding device 13 continuously sends out the reminding signal.
Through the above steps, when the electric quantity of the battery 12 of the handheld device 10 is lower than the preset electric quantity, and the handheld device 10 is in the idle state for longer than the idle time, the handheld device 10 will immediately send out a reminding signal through the reminding unit to help the user quickly find the handheld device 10, and charge the handheld device 10, thereby effectively reducing the possibility that the handheld device 10 is lost due to the fact that the electric quantity is too low and the handheld device 10 is in the power-off state.
The examples listed above are intended to illustrate possible implementations of examples of the invention, which are not limited to the embodiments exemplified above, but rather should be construed to cover modifications and variations within the scope of the inventive concept disclosed herein.
