Description

Electronic device with power recording function and power recording method thereof
Technical Field
The present invention relates to an electronic device with a power recording function and a power recording method thereof, and more particularly, to an electronic device with a power recording function and a power recording method thereof, wherein the electronic device measures and stores power of a battery when entering a shutdown procedure, so that the electronic device can omit the measurement of the battery when starting up.
Background
Currently, most people use a camera (such as a digital camera, a smart phone, etc.) to capture images to leave a wonderful photo or movie. When a general camera is turned on, the following two items of information about the remaining battery power are generally required:
1. type of Battery (Battery Type): for example, the type of the third battery or the lithium battery can be used for judging the discharge characteristic of the battery so as to estimate the residual power more accurately; and
2. battery Level (Battery Level): the battery can provide an operating voltage to ensure that the remaining power is at least sufficient to push out and retract the lens of the camera, so as to avoid the situation that the lens is exposed after the camera is turned off.
To obtain the above two information related to the Battery, a Battery power measurement (Battery measurement) procedure is performed during the power-on process, which applies a considerable Load (Full Load) to the Battery, and after a period of time, the working voltage provided by the Battery under the Load is observed, and the remaining power is determined according to the working voltage. This load testing (Full load testing) takes some time, and the camera cannot continue the subsequent boot process (push, enter live view, etc.) until the process is finished.
As can be seen from the above, performing the battery power measurement requires a heavy load on the battery and must last for a period of time (about 70-100 ms) before the operating voltage can be measured correctly. When the user presses the power button, the amount of time it takes to execute the battery power measurement procedure will affect the following two time points:
1. the screen displays the time of the live view frame.
2. The time at which the photograph can actually be taken.
In addition, the battery is damaged by the frequently executed load test, which can easily reduce the service life of the battery. Finally, since the third battery is prone to be unstable, and even in the absence of power, it may be detected that the battery is still sufficient, and because of the possibility of such misjudgment, the battery power measurement performed at the first power-on time usually has a higher acceptable operating voltage standard, and therefore, it may be judged that the battery is insufficient if the battery power is still sufficient.

Detailed Description
The electronic device having the power recording function of the present invention may be various electronic devices having an image capturing function, such as a Digital Camera (Digital Camera), a Camera Phone (Camera Phone), a smart Phone (Smartphone), or a Digital Video Camera (Digital Video Camera). However, the power recording method of the present invention is not only applicable to battery measurement of an image capturing device, but also applicable to other electronic devices using the same battery. The following embodiments mainly use the image capturing device to perform the description of the measurement of the electric quantity of the battery, but not limited thereto.
Referring to fig. 1, a schematic diagram of a first embodiment of an electronic device with a power recording function according to the invention is shown. As shown, the electronic device 1 may be a camera, and includes a power module 11, a measurement module 12, a storage module 13, and a processing module 14. The signal input/output port of the power module 11 is electrically connected to the signal input/output port of the measurement module 12, the signal transmission port of the measurement module 12 is electrically connected to the signal reception port of the storage module 13, and the signal transmission port of the storage module 13 is electrically connected to the signal input/output port of the processing module 14. The power module 11 may be a general battery such as a lithium battery, a zinc-manganese battery, or a rechargeable battery such as a lithium ion battery, a lead-acid battery, a nickel-cadmium battery, or the like, and each battery may be further subdivided into various batteries of different types, for example, the dry battery may be a third battery, a fourth battery, or the like. The storage module 13 can be a built-in memory, but not limited thereto.
In the first embodiment, when the electronic device 1 is to be powered off, the measuring module 12 performs a battery power measuring procedure on the power module 11 during a buffer time before the electronic device is powered off to measure the type 111 of the power module 11 and the remaining power 112. After the type 111 and the current power value 112 of the power module 11 are measured, the storage module 13 stores the measured information (the type 111 and the power value 112), so that when a user wants to use the electronic device 1 to photograph and turn on the electronic device, the type 111 and the current remaining power value 112 of the power module 11 can be taken out from the storage module 13 through the processing module 14, and then the electronic device 1 enters a live-view frame to enable the user to start photographing.
In the above description, the measurement of the power module 11 is mainly performed when the electronic device 1 is turned off, so that when the electronic device 1 is turned on, the procedure of measuring the type and the current power value of the power module 11 can be omitted and the power module can be directly taken out from the storage module 13, thereby greatly reducing the time from the turning on of the electronic device 1 to the entering of the live view frame. It should be noted that, when the electronic device 1 is turned off, the Battery power measurement (Battery metering) operation is performed on the power module 11, and a relatively large load does not need to be applied to the power module 11 for performing a load test, so that damage to the power module 11 can be effectively reduced.
Referring to fig. 2, a flowchart of a power recording method according to a first embodiment is shown. As shown in the figure, the steps of the electronic device 1 in the first embodiment for measuring the battery power are as follows: s21: measuring the type 111 and the current remaining power 112 of the power module 11 by the measuring module 12 during a buffering period before the electronic device 1 is powered off; s22: storing the type 111 and the power value 112 of the power module 11 measured by the measuring module 12 by using the storage module 13; and S23: the type 111 and the current power value 112 of the power module 11 are retrieved from the storage module 13 by the processing module 14 when the electronic device 1 is turned on.
Referring to fig. 3, a schematic diagram of a second embodiment of the electronic device with power recording function according to the invention is shown. As shown, the electronic device 3 may be a camera, etc., but not limited thereto. The electronic device 3 includes a power module 31, a measurement module 32, a storage module 33, a processing module 34, a detection module 35 and a clock module 36. The signal input/output port of the power module 31 is electrically connected to the signal input/output port of the measurement module 32 and the signal input/output port of the detection module 35, the signal transmission port of the measurement module 32 is electrically connected to the signal reception port of the storage module 33 and the signal input/output port of the processing module 34, the signal input/output port of the processing module 34 is electrically connected to the signal transmission port of the storage module 33 and the signal transmission port of the clock module 36, and the signal input port of the clock module 36 is electrically connected to the signal transmission port of the detection module 35. The power module 31 may be a general battery or a rechargeable battery. The storage module 33 can be a built-in memory. The Clock module 36 includes a temporary storage unit 361, the Clock module 36 is a Real-Time Clock (RTC), when the electronic device 3 is powered off, the Clock module 36 is used to record the information of the electronic device 3 when powered off into the temporary storage unit 361, and the information of the electronic device 3 when powered off includes the Time when powered off.
In the second embodiment, when the electronic apparatus 3 is powered off, the measuring module 32 measures the battery power of the power module 31 during a buffering period before the power off to measure the type 311 of the power module 31 and the current remaining power value 312, and then the storage module 33 stores the measured type 311 of the power module 31 and the current power value 312. The detection module 35 also determines whether the power module 31 is removed when the electronic device 3 is powered off, and if the detection module 35 determines that the power module 31 is removed, the content of the register unit 361 in the clock module 36 is changed.
In the above description, when the electronic device 3 is powered on, the processing module 34 reads the contents stored in the register 361 of the clock module 36, so as to determine whether the power module 31 has been removed. If the power module 31 is removed, the processing module 34 will drive the measuring module 32 to measure the power value 312 and the type 311 of the power module 31. If the power module 31 is not removed, the processing module 34 directly retrieves the type 311 and the current power value 312 of the power module 31 measured before the electronic device 3 is powered off from the storage module 33. Based on the type 311 and the current power value 312 of the power module 31 measured by the measuring module 32 when the electronic device 3 is powered off, the electronic device 3 does not need to measure the power module 31 when powered on, and can directly obtain the power from the storage module 33, so as to reduce the time from the powering on of the electronic device 3 to the photographing. Moreover, since the power measurement of the power module 31 is started when the electronic device 3 is powered off, and the detection module 35 determines whether the power module 31 is removed, the power value 312 can be measured more accurately than the power measurement of the power module 31 only when the electronic device is powered on.
Referring to fig. 4, a flowchart of a power recording method according to a second embodiment is shown. As shown in the figure, the steps of the electronic device 3 in the second embodiment for measuring the battery power are as follows: s41: measuring the type 311 and the current power value 312 of the power module 31 by the measuring module 32 during a buffering period before the electronic device 3 is powered off; s42: storing the type 311 and the power value 312 measured by the measuring module 32 by using the storage module 33; s43: using the detection module 35 to detect whether the power module 31 is removed when the electronic device 3 is powered off; s44: the temporary storage unit 361 of the clock module 36 is used to record the information when the electronic device 3 is powered off, if the detection module 35 detects that the power module 31 is removed, the information content stored in the temporary storage unit 361 will be changed; s45: the processing module 34 reads the information content stored in the temporary storage unit 361 when the electronic device 3 is powered on to determine whether the power module 31 is removed when powered off; s46: if the power module 31 is not removed, the type 311 and the current power value 312 of the power module 31 are retrieved from the storage module 33 through the processing module 34, and if the power module 31 is removed, the processing module 34 drives the measurement module 32 to measure the power module 31.
Referring to fig. 5, a schematic diagram of a third embodiment of the electronic device with power recording function according to the invention is shown. As shown in the figure, the electronic device of the present invention is an image capturing device 5, which comprises a battery 51, a chip 52 and a memory 53, wherein the signal port of the chip 52 is electrically connected to the signal ports of the battery 51 and the memory 53, respectively. The chip 52 includes a measurement module 521, a processing module 522, a detection module 523 and a clock module 524, and the clock module 524 includes a register 5241. The image capturing device 5 includes a screen 54 and a lens 55.
In the third embodiment, when the user finishes using the image capturing device 5 and wants to shut down, the measurement module 521 in the chip 52 starts to measure the battery 51 during a buffer period from the time when the shutdown button is pressed to the time when the shutdown is completed, so as to measure the type 511 and the current power value 512 of the battery 51, and store the type 511 and the current power value 512 in the memory 53. The detection module 523 in the chip 52 can detect whether the battery 51 has been removed when or after the image capturing device 5 is powered off, and if so, the content stored in the register 5241 in the clock module 524 in the chip 52 can be changed.
In the above description, when the user wants to use the image capturing device 5 and turn it on, the processing module 522 in the chip 52 reads the contents of the register 5241 to determine whether the battery 51 has been removed. If the battery 51 is not removed, the processing module 522 will directly retrieve the type 511 and the current power value 512 of the battery 51 stored in the image capturing device 5 before the previous shutdown from the memory 53. If the processing module 522 determines that the battery 51 has been removed, the processing module 522 drives the measuring module 521 to measure the power of the battery 51. After the information of the type 511 and the current power value 512 of the battery 51 is obtained, the screen 54 of the image capturing device 5 enters a live view frame, and the power display image 541 of the current power value 512 of the battery 51 is displayed on the screen 54, and the lens 55 of the image capturing device 5 is also pushed out, so that the user can take a picture by using the image capturing device 5.
In the above description, if the battery 51 is not removed, the processing module 522 directly obtains the information related to the current power value 512 of the battery 51 from the memory 53, so that the waiting time for the lens 55 to be pushed out and the screen 54 to enter the live view frame when the power-on key of the image capturing device 5 is pressed is shortened. It should be noted that, during the process of using the image capturing device 5, the measuring module 521 in the chip 52 can measure the power value 512 of the battery 51 at an interval, so as to determine the current power consumption of the battery 51 in real time.
Referring to fig. 6, a flowchart of a power recording method according to a third embodiment is shown. As shown in the figure, the steps of the image capturing device 5 in the third embodiment for measuring the battery power are as follows: s61: the image capturing device 5 enters a shutdown procedure; s62: measuring the type 511 and the current power value 512 of the battery 51 by using a measuring module 521; s63: storing the measured type 511 and the current power value 512 of the battery 51 through the memory 53; s64: using the detection module 523 to detect whether the battery 51 has been removed, so as to determine the content of the register 5241 of the clock module 524; s65: the image capturing device 5 enters a startup procedure; s66: the content of the register 5241 is read by the processing module 522 to determine whether the battery 51 has been removed; s661: if the battery 51 is not removed, the type 511 and the current power value 512 of the battery 51 are retrieved from the memory 53 by the processing module 522; s662: if the battery 51 has been removed, the processing module 522 is used to drive the measuring module 521 to measure the type 511 and the current power value 512 of the battery 51; and S67: the screen 54 of the image capturing device 5 enters the live view frame and the lens 55 is pushed out to prepare for capturing an image.
In summary, the electronic device with power recording function and the power recording method thereof of the present invention measure the power of the battery before the electronic device is turned off, store the power, detect whether the battery is removed, and directly take out the information such as the power value of the battery from the memory when the electronic device is turned on. In addition, because the power measurement of the battery of the electronic device before the power off is not the load test action as that of the power on, the consumption of the battery can be effectively reduced, and the service life of the battery is prolonged.
The above description is of the preferred embodiment of the present invention and the technical principles applied thereto, and it will be apparent to those skilled in the art that any changes and modifications based on the equivalent changes and simple substitutions of the technical solution of the present invention are within the protection scope of the present invention without departing from the spirit and scope of the present invention.
