Description

[Technical Field]

[0001] The present invention relates to a photographing device and a data transmission method, and more particularly to a photographing device with a network transmission function and a media data upload method thereof. [Background technology]

[0002] In some situations, it is more convenient to use an external power source, such as a commercial power source, in order to properly store and transmit data. However, in other situations, when an external power source is unavailable or temporarily unavailable, power can only be supplied from the battery in the device's internal power module. However, due to limited battery capacity, when the network status is unstable, repeated transmissions may be required to upload media data, consuming a large amount of power. If media data uploads are delayed or not uploaded, due to storage capacity limitations, stored media data must be uploaded promptly to avoid overwriting unuploaded media data. This reveals that when powered by an internal power source, the prior art fails to consider the relationship between battery capacity, storage capacity, and network environment, potentially resulting in problems such as media data being overwritten or the battery running out of power, making it impossible to perform certain operations. Summary of the Invention [Problem to be solved by the invention]

[0023] Hereinafter, the embodiments of the present invention will be further explained with reference to the drawings.

[0024] (Example) As shown in Figure 1, an embodiment of the photographing device with network transmission capability and the media data uploading method thereof of the present invention is configured as a photographing device with network transmission capability. The photographing device may be a security camera installed in a fixed location and capturing images within a predetermined area, a mobile handheld camera or small camera, or a mobile camera worn on a specific part of the user's body. A common feature of these cameras and photographing devices is that they not only store captured media data in their own storage modules, but also upload the stored media data to a server via a network for storage, thereby solving the problem of insufficient storage module capacity during long-term shooting and also resolving the issue of data security.

[0025] Specifically, as shown in FIG. 1 , in this embodiment, the photographing device with network transmission function includes a photographing module, a control module, a storage module, and a power supply module. The photographing module, under the control of the control module, acquires media data and transmits it to the storage module. The photographing module includes a camera and a signal processing module that converts image signals acquired by the camera into digital signals. In addition, the photographing module may further include an artificial intelligence module that starts photographing only when it detects a target of a predetermined shape or the appearance of a moving object within a predetermined area, thereby reducing the amount of media data or making monitoring more efficient when used for security or surveillance. The storage module stores the received media data and uploads the stored media data to a server via a network in a set situation. The control module maintains the current state of the photographing device or activates the device to enter a static upload mode based on the current state of the photographing device, the state of the power supply module, and the remaining storage capacity of the storage module. The static upload mode includes an operation in which the photographing device wakes up from sleep at a set wake-up time and uploads the media data stored therein. The power supply module supplies power to each module of the photographing device. In this embodiment, the situations in which media data uploading is set include uploading media data under operating conditions and uploading data when the conditions for static uploading mode are met, and both of these situations are described in detail below. Naturally, in both situations, uploading media data is achieved under the control of the control module.

[0026] In this embodiment, the above-mentioned photographing device with network transmission function may be a surveillance photographing device, a mobile photographing device, or a handheld photographing device, and may be installed at a fixed position indoors or outdoors, or may move with the user wearing it or be carried by the user. Therefore, when powering the photographing device, a voltage converted from an AC power source or a battery built into the power supply module of the photographing device may be used. The control module detects various states of the photographing device and causes each module of the photographing device to perform a corresponding operation according to these states.

[0027] Specifically, for the above-mentioned photographing device equipped with a network transmission function, regardless of the state of the photographing device, such as uploading while photographing or in sleep mode, the control module must determine the state of the photographing device at a set periodic time, and if the photographing device is currently in an operating state and has never entered sleep mode, or if it has entered sleep mode but the current network transmission speed or network condition is good, it must maintain the operating state and upload the collected data to the server. If the photographing device is currently in a sleeping state (is shutting down), it must determine the state of the storage module and power supply module to determine whether to enter static upload mode or continue sleeping.

[0028] In the static upload mode, when the startup time arrives, the control module wakes up the photographing device and causes the storage module to upload the media data stored therein to the server if it determines that the number of used storage units in the storage module is greater than a first storage unit setting value and the remaining power of the power supply module is greater than a first power setting value, or that the power supply module is powered by an external power source. The first storage unit setting value includes 60 to 70% of all storage units. The first power setting value is 12 to 20% of the total power of the battery built into the power supply module.

[0029] In this embodiment, in the static upload mode, when the control module detects that the remaining power of the power supply module is less than a second power setting value, the control module causes the imaging device to enter a sleep state within a set time, where the second power setting value comprises 10% of the total power.

[0030] In other words, even in the static upload mode, whether to perform uploading must be determined according to the specific conditions of the storage module, the power supply module, and the network. If the storage unit usage of the storage module does not reach the first storage unit setting value, or if the power supply module is not powered by an external power source, or if the remaining power of its internal battery is insufficient, the upload operation will not be performed. If the set startup time has not yet arrived or the network condition is not ideal, the imaging device will not wake up from the sleep state, or after waking up, will return to the sleep state without performing the upload operation. In short, the static upload state of this embodiment flexibly considers the storage unit usage of the storage module, the state of the power supply module, and the state of the network, and takes different actions according to the conditions, thereby achieving a balance between the storage module, the power supply module, and the network transmission conditions. As a result, the imaging device has more balanced data processing capabilities, longer operating time, and better adaptability than conventional imaging devices.

[0031] In this embodiment, the camera with network transmission function further includes a network monitoring module that periodically measures the network transmission speed between the camera and the server, selects a time period when the network transmission speed is maximum as a transmission time period, and sets a startup time in the transmission time period. In this embodiment, when the camera itself is in an operating state, i.e., not in a static upload mode, maintaining the current state of the camera includes continuing to obtain media data and upload it to the server via the network.

[0032] In this embodiment, the network includes a 5G wireless communication network. Although the 5G network has a high transmission speed, its transmission efficiency may vary depending on the time of day due to significant environmental influences. When the network transmission efficiency is low, data transmission may require multiple data transmissions or returns, which consumes a lot of energy. Therefore, it is particularly necessary to determine the network transmission speed or status as described above to avoid wasting valuable remaining battery power when the network environment is poor. This determination can avoid initiating media data upload when the network environment is poor, saving a large amount of energy wasted on ineffective transmissions and significantly improving battery energy efficiency.

[0033] Overall, the biggest problem solved by this invention is to balance three factors: storage capacity, power consumption, and network traffic. When used for a long period of time, a photographing device equipped with a network transmission function inevitably encounters situations where the storage capacity or power consumption is insufficient. In this invention, a video upload is started based on a preset storage capacity limit, then a preset timestamp is used to determine the start time of the upload, and finally, the power consumption situation determines whether to upload. If the power consumption does not reach the preset value, the device enters sleep mode until the next appropriate timestamp is reached and uploading is performed, thereby achieving a balance between storage capacity, power consumption, and network transmission speed.

[0034] In this embodiment, the storage capacity limit is 30%, that is, when the storage capacity of the network shooting device is lower than the limit of 30% and the other conditions mentioned above are met, the control module will start the video upload operation.

[0035] Unlike other network cameras, the camera of the present invention can transmit using a 5G network, has a built-in battery that can be charged by converting AC power, and can be powered using the converted AC power. When moving or when connecting to external AC power is difficult, the built-in battery is sufficient to operate the network camera of the present invention until it runs out of power. When live streaming is not required, a shooting method suitable for dynamic scenes can be provided. In dynamic shooting environments, the network transmission status can be automatically detected and the captured media data can be uploaded to the server at the maximum speed. When network transmission conditions are not ideal, an appropriate transmission time can be customized.

[0036] The present invention further relates to a method for uploading media data by a photographing device, the photographing device being the photographing device with a network transmission function, where uploading media data means uploading stored media data to a server via a network, thereby ensuring that a storage module on the photographing device has sufficient storage space to store the acquired media data. As shown in Figure 2, the method for uploading media data by a photographing device includes the following steps S11 to S16. In step S11, it is determined whether the photographing device is currently sleeping. If it is sleeping, step S12 is executed. If it is not sleeping, step S13 is executed. Note that this step is periodically executed by the control module of the photographing device, and the subsequent steps are also executed by the control module or by a module with the involvement of the control module. When the photographing device starts to be powered, is in operation, or is in sleep, the control module periodically executes this step and the subsequent steps.

[0037] In step S12, the current state is maintained. In this step, the photographing device is not in a sleep state but in an operating state, so the current operating state is maintained in this step. In this step, the following two situations may occur: one is that the photographing device has never entered a sleep state; the other is that the photographing device has entered a sleep state before but is not currently in a sleep state and the network condition is good (the network transmission speed is high or the current time is suitable for network transmission). In this situation, in addition to continuing to obtain media data, the media data is uploaded, i.e., transmitted to the server via the network.

[0038] In step S13, it is determined whether the used storage capacity of the storage module exceeds the first set capacity. If it does, the next step is executed; if it does not, the process jumps to step S16. Because the photographing device is currently in sleep mode or will remain in sleep mode until step S11 is executed, this step must determine the amount of storage units currently in use or remaining in the storage module. If the amount of storage exceeds the first set capacity, for example, exceeds 70%, this indicates that the storage module is low on storage space and will interfere with the storage of subsequently acquired media data. Therefore, if the conditions are met, some or all of the media data must be uploaded to free up a corresponding portion of the storage units in the storage module and increase the number of free storage units in the storage module, thereby minimizing the impact of a lack of storage units on subsequent media data storage.

[0039] In step S14, it is determined whether the power supply module is powered by an external power source or whether the remaining power of its battery is greater than the first set power amount, and if so, execute the next step; if not, jump to step S16.

[0040] In step S15, the static upload mode is entered, in which the wake-up time is obtained, and after the wake-up time is reached, the photographing device is woken up to upload media data.

[0041] In step S16, the current determination is completed and the process returns to sleep. The above steps are executed by the control module and are constantly repeated at set time intervals, so that when the photographing device uploads media data, it is in a period of good network traffic and good reliability of the power supply module, thereby achieving a balance between network traffic, the status of the power supply module, and the remaining storage capacity of the storage unit, and ensuring the reliability of its operation.

[0042] When the photographing device enters the static upload mode, the steps performed by it specifically include steps S21 to S24, as shown in FIG. In step S21, it is determined whether the current power control conditions (Power Control Chip, PCC) are met and whether the power is supplied by the battery of the power supply module. If not, it jumps to step S23. If yes, it executes the following steps. The above power control conditions refer to the wake-up time being within the set network transmission time slot and the remaining power of the battery being 15% or more of its total power. If these conditions are met, the device will wake up; if these conditions are not met, the device will continue to sleep.

[0043] In step S22, it is determined whether the remaining battery power of the power supply module is less than the second set power amount. If it is not less than the second set power amount, return to step S21; if it is less than the second set power amount, execute the next step. In this embodiment, the second set power amount is 10% of the total battery power amount, and if it is found that the remaining battery power amount is less than the second set power amount, it means that the power amount cannot support the device to upload media data.

[0044] In step S23, the device enters sleep mode after a set time, for example, 5 minutes, because the battery power is low and cannot support further media data transmission.

[0045] Step S24 uploads the media data, and the uploaded media data is deleted from the storage module, thereby freeing up sufficient storage units.

[0046] In this embodiment, determining the current network transmission speed is realized by a network monitoring module, the specific steps of which are shown in Figure 4, including steps S31 to S33. In step S31, the media data is divided into multiple files. In this step, the media data waiting to be uploaded is processed so that it exists as multiple files, and each file is a media data segment of only 10 seconds. Essentially, the acquired media data waiting to be uploaded is divided into multiple data segments according to the set time.

[0047] In step S32, the total data volume of files uploaded within a set time is calculated. In this step, one time period is identified, and the data volume of files uploaded within that time period is calculated. For example, if two files are uploaded within 30 seconds, and each file has a data volume of 30 MB, the total data volume is 60 MB.

[0048] In step S33, the current network transmission speed is obtained, and then divided to obtain the amount of data transmitted through the network per unit time.

[0049] In this embodiment, after the network transmission speed is obtained as described above, it is compared with the set transmission speed. If the current network transmission speed is higher than the set transmission speed, it is determined that the current network transmission speed is high. If the network transmission speed is high for a certain period of time, that period is set as a transmission time slot. There may be multiple transmission time slots within a unit of time such as one day, and they may be distributed over different periods of the day, such as early morning and late night, and the length of each transmission time slot may be the same or different depending on the situation.

[0050] The above examples merely illustrate some embodiments of the present invention, and although they are specifically and in detail described, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make appropriate modifications and improvements without departing from the spirit of the present invention, and these also fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention is governed by the claims set forth below.
