[0052] The embodiments of the present application provide a power consumption control method and device for a communication device, which are used to determine the startup mode of a cellular module and the power supply mode for the cellular module according to the power consumption of functional modules in the communication device, so as to realize reliable, stable and smooth transmission of bitstreams within the maximum power supply range of an external power supply for the cellular module.

[0053] Among them, the method and the device are based on the same inventive concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be elaborated.

In addition, terms such as "including" and "comprising" should be understood as not limiting the described embodiments to only the features already mentioned; such examples and embodiments may also include features, structures, units, modules, etc. not specifically mentioned.

[0056] The following describes each embodiment of the present application in detail with reference to the drawings in the specification. It should be noted that the display order of the embodiments of the present application only represents the sequence of the embodiments, and does not represent the superiority or inferiority of the technical solutions provided by the embodiments.

[0057] It should be noted that the technical solution provided by the embodiments of the present application is described by taking reducing the overall power consumption of 5G monitoring devices as an example, but is not limited thereto.

[0058] Some nouns appearing in the text are explained below:

[0059] 1. In the embodiments of this application, the term "intrinsic safety" means intrinsically safe, and explosion protection can be achieved through the energy-limiting of the safety barrier;

[0060] 2. In the embodiments of this application, the term "bitstream" refers to the data traffic used by a video file per unit time, also called the bit rate, which is the most important part in the picture quality control of video coding;

[0061] 3. In the embodiments of this application, the term "pulling the stream" refers to the process in which the image information collected by a monitoring device is transmitted to the cloud platform through a cellular module (such as 4G, 5G or Ethernet, etc.) and the video information is displayed on the cloud platform.

[0062] In the overall power consumption of a communication device, the power consumption of the cellular 5G module accounts for a relatively high proportion in the overall device power consumption. Under different working modes, wireless interference, etc., the transmission power of the cellular module is different. The farther the distance from the base station, the higher the transmission power required for the cellular module to send and receive data. In some cases where the signal coverage is poor and the installation location of the device is blocked, etc., the power consumption of the 5G module can reach up to 4.5W at most, which will be a huge challenge for the intrinsically safe scenario with strict requirements for power consumption. How to reduce the overall power consumption of 5G devices is an urgent problem to be solved currently.

[0063] To solve the above problems, the embodiments of this application propose a power consumption control method for a communication device, which can be applied to, for example, 5G monitoring devices. Within the maximum supply range of the external power supply of the communication device (i.e., the charger of the communication device), the stable and reliable transmission of the video stream is achieved through the parameter adjustment of internal key modules and the switching of the cellular module and the SIM card, thereby avoiding serious problems such as insufficient power supply of the external power supply due to excessive power consumption of the cellular module.

[0064] See Figure 1 , the communication device, for example, includes a DSP module, a cellular module (4G, 5G module), a SIM management module (such as SIM1, SIM2, i.e., SIM cards of different operators), an internal battery, an external power supply (i.e., the charger of the communication device, which provides DC power supply for other modules of the communication device), a power management module, and key peripheral modules (such as image processing, AI (Artificial Intelligence), windshield wiper, fill light, pan-tilt, speaker);

[0065] The DSP module is the main processor of the communication device and is used to implement all services of the communication device by controlling the work of other modules;

[0066] The SIM management module is used to switch SIM cards for 4G and 5G modules, that is, assign SIM1 to the 4G module and SIM2 to the 5G module, or assign SIM2 to the 4G module and SIM1 to the 5G module. Here, SIM1 and SIM2 are SIM cards of different operators;

[0067] The power management module is used to achieve power switching and perform power supply management for 4G and 5G modules. It can switch the hardware circuit switch to achieve the purpose of supplying external power or internal battery power to the 4G and 5G modules, realize charging the internal battery through the external power supply, and is also used to count the output power consumption of the external power supply or internal battery;

[0068] The peripheral module includes some key functional modules of the communication device, such as an AI module for intelligent analysis of video images, a pan-tilt for realizing the rotation of the monitoring device lens, and so on.

[0069] Since the transmission power consumption of the cellular module is strongly related to the current cellular environment, the worse the cellular environment quality (such as long distance, large interference, etc.), the greater the transmission power of the cellular module. The maximum power consumption of the 4G module is more than 2W, and the maximum power consumption of the 5G module can exceed 5W. To ensure that the overall power consumption of the communication device is lower than the maximum power consumption of the external power supply, in the embodiment of this application, during the startup process of the communication device, the startup of the cellular module is lagged, and the power consumption of other modules of the communication device except the cellular module is preferentially counted.

[0070] See Figure 2 , the specific steps for determining the optimal combination of cellular module and SIM card (the external power supply supplies power to the 4G module, and the internal battery supplies power to the 5G module) provided by the embodiment of this application include:

[0071] Step S11: The communication device is powered on, but the cellular module is not powered on temporarily, and the internal battery is in a state of neither charging nor discharging;

[0072] Step S12: After other modules are started up, the DSP module queries the current remaining power consumption of the external power supply (maximum output power consumption - current output power consumption) through the power management module. This current remaining power consumption is the difference between the maximum output power consumption of the external power supply and the current output power consumption. Among them, for the maximum output power consumption, the power management module obtains the limit output power consumption value marked on the nameplate of the external power supply through the power adapter, and the current output power consumption is the power consumption value output by the external power supply for all modules of the communication device (that is, the sum of the power consumption of other modules that are currently using the external power supply for power supply, and the power consumption of each module is obtained through the power management module).

[0073] Assume that the current remaining power consumption of the external power supply is T1, the preset maximum power consumption of the 4G module is T2, and the preset maximum power consumption of the 5G module is T3. Since the maximum power consumption of the 4G module is usually lower than that of the 5G module, by comparing the magnitudes of T2 and T1, it is possible to determine whether the external power supply can power the cellular module.

[0074] If T2 ≤ T1, it means that the external power supply can meet the maximum power consumption requirements of the 4G module. The SIM management module assigns SIM cards to the 4G module and the 5G module respectively (for example, using SIM cards of two operators, namely SIM1 and SIM2. Assign SIM1 to the 4G module, i.e., 4G - SIM1; assign SIM2 to the 5G module, i.e., 5G - SIM2). Then, the power management module completes the hardware circuit switching: power the 4G module with the external power supply and power the 5G module with the internal battery.

[0075] Step S13: After the 4G and 5G modules are powered on simultaneously, the 4G and 5G modules use the corresponding SIM cards assigned by the SIM management module to dial up the Internet and register with the cloud platform.

[0076] Step S14: The DSP module performs dual - link video stream transmission based on the 4G and 5G modules, and sends the video streams to the 4G and 5G modules respectively. The 4G and 5G modules then forward the video streams to the cloud platform.

[0077] Step S15: The power management module obtains the current output power consumption of the internal battery and the external power supply. At the same time, the stream transmission module obtains the smoothness of the video stream transmission on the 4G link and the 5G link. Among them, the smoothness of the video stream transmission can be determined by measuring the packet loss rate, that is, counting the total number of video stream packets sent by the DSP module within a unit time, and the total number of video stream packets received by the cloud platform within the same unit time. Calculate the difference between the two to obtain the number of video stream packets that failed to be sent within the unit time. Divide the number of failed video stream packets by the total number of video stream packets sent by the DSP module within the unit time to obtain the packet loss rate. The larger the packet loss rate, the more stuttering the image, that is, the worse the transmission smoothness.

[0078] The SIM management module re - assigns SIM cards to the 4G module and the 5G module (for example, assign SIM2 to the 4G module, i.e., 4G - SIM2; assign SIM1 to the 5G module, i.e., 5G - SIM1), and repeat the above steps S13 - S15.

[0079] At this time, the power consumption of the 4G module is the current output power consumption of the external power supply, and the power consumption of the 5G module is the current output power consumption of the internal battery. Compare the power consumption and the smoothness of the transmitted video stream under the above four combinations of 4G-SIM1, 4G-SIM2, 5G-SIM2, and 5G-SIM1, and select the combination with the best smoothness (i.e., the lowest packet loss rate and no stuttering) and the smallest power consumption for service stream pulling.

[0080] Assume that under the 4G-SIM2 combination obtained above, the smoothness of the video stream transmission is the best and the power consumption is the lowest. Use this combination for stream pulling, and through the power management module, power off the 5G module to make the 5G module stop working. At the same time, switch the internal battery to the charging state of the external power supply, and use the remaining power consumption of the external power supply to charge the internal battery. That is, the external power supply at this time supplies power to the 4G module and also charges the internal battery.

[0081] See Figure 3 , another specific step for determining the optimal combination of the cellular module and the SIM card (the internal battery supplies power to the 4G module or the 5G module) provided by the embodiment of the present application includes:

[0082] Step S21: Power on the communication device, but do not power on the cellular module temporarily, and the internal battery does not charge or discharge.

[0083] Step S22: After other modules are started, the DSP module queries the current remaining power consumption of the external power supply through the power management module.

[0084] After the communication device is started, if there are more key peripheral modules involved in the current service, more power supply is required. For example, if the external speaker and the pan-tilt inspection are turned on, at this time, the external power supply cannot supply power to the 4G module because it cannot meet the maximum power consumption requirement of the 4G module (i.e., T2>T1). At this time, the power supply switch is switched through the power management module, and the internal battery supplies power to the 4G module, and the SIM management module assigns a SIM card (such as SIM1) to the 4G module.

[0085] Step S23: The 4G module dials the Internet using SIM1, the DSP module sends the video stream to the 4G module, and the 4G module forwards the received video stream to the cloud platform after receiving it.

[0086] Step S24: After a preset time (such as 20 s), obtain the current output power consumption of the internal battery through the power management module and calculate the smoothness of the video stream transmission.

[0087] If the smoothness of the video stream transmission is good (i.e., no stuttering) under the current 4G-SIM1 combination, and the power consumption of the 4G module is less than the current remaining power consumption of the external power supply, then supply power to the 4G module through the external power supply through the power management module and power off the 5G module.

[0088] Step S25: If the smoothness of video stream transmission is poor (i.e., there is lag) under the current 4G-SIM1 combination, it indicates that the current 4G network does not meet the service requirements. If there is a switchable SIM card, the SIM card of the 4G module is switched to, for example, SIM2 through the SIM management module, and the above steps S23 - S25 are repeated;

[0089] If the lag phenomenon of the 4G module still cannot be improved after SIM card switching, the cellular module is switched to a 5G module, and SIM1 is allocated to the 5G module;

[0090] Step S26: The 5G module dials the Internet using SIM1, the DSP module sends the video stream to the 5G module, and the 5G module forwards it to the cloud platform after receiving the video stream; after a preset time (e.g., 20s), the current output power consumption of the internal battery is obtained through the power management module, and the smoothness of video stream transmission is calculated; if the smoothness of video stream transmission is poor under the current 5G-SIM1 combination, the SIM card of the 5G module is switched to SIM2 through the SIM management module;

[0091] Generally, it is necessary to perform the dial-up Internet access and video stream pulling operations under each combination of 4G-SIM1, 4G-SIM2, 5G-SIM1, and 5G-SIM2 in sequence, and count the power consumption of the cellular module and the smoothness of video stream transmission under each combination. By comparing the transmission smoothness and power consumption of each combination, the combination with the best smoothness (i.e., the lowest packet loss rate) and the smallest power consumption can be selected.

[0092] If it is finally determined that the smoothness of video stream transmission is the best under the 5G-SIM2 combination, assuming the current power consumption of the 5G module is T4, when T4 < T1, the power supply mode of the 5G module is switched to external power supply through the power management module, and the internal battery is charged with the remaining power consumption of the external power supply; when T4 > T1, it means that the current remaining power consumption of the external power supply cannot meet the maximum power consumption requirement of the 5G module, so the output power consumption of the external power supply is reduced by adjusting key peripheral modules such as the ability of the fill light, the rotation speed of the pan-tilt, and the encoding and decoding performance, that is, the current remaining power consumption T1 of the external power supply is increased. This adjustment action is continuously performed, and the current remaining power consumption T1 of the external power supply is continuously updated until T4 < T1.

[0093] In some embodiments, during the operation of the key peripheral module, the DSP module continuously monitors the configuration changes of the key peripheral module. Configuration changes such as adjusting the speaker volume will affect the output power consumption of the external power supply, thereby affecting the current remaining power consumption of the external power supply. When the configuration of a certain key peripheral module changes, the DSP module will estimate the power consumption change caused by the configuration change of the key peripheral module to determine whether additional power management operations are required. If the key peripheral module performs a power consumption reduction operation, no additional power management operations are required; if the key peripheral module performs a power consumption increase operation (such as increasing the speaker volume), calculate the power consumption increase amount (set as T6) caused by the current configuration change. When T6 < T1, it means that the current remaining power consumption of the external power supply can meet the power consumption requirements of the key peripheral module configuration change, and no power management is required; when T6 > T1, it means that the current remaining power consumption of the external power supply cannot meet the power consumption requirements of the key peripheral module configuration change. At this time, other key peripheral modules need to be adjusted (such as turning off AI intelligent analysis) to reduce the output power consumption of the external power supply, thereby increasing the current remaining power consumption of the external power supply. If T6 < T1 still cannot be achieved, the configuration modification of increasing the power consumption of the key peripheral module is not executed.

[0094] The above power consumption reduction operations include, for example, reducing the speaker volume, reducing the pan-tilt rotation speed, increasing the inspection interval of the monitoring device, turning off the AI image analysis function, reducing the brightness of the fill light, etc.; the power consumption increase operations include, for example, increasing the speaker volume, accelerating the pan-tilt rotation speed, shortening the inspection interval of the monitoring device, turning on AI intelligent analysis, increasing the brightness of the fill light, etc.

[0095] In summary, referring to Figure 4 , a power consumption control method for a communication device provided by an embodiment of the present application includes:

[0096] Step S101: When starting the communication device, suspend starting the cellular module in the communication device and count the power consumption of other modules in the communication device except the cellular module;

[0097] Among them, the communication device, such as a monitoring device, can also be any user terminal; the cellular module includes, for example, a 4G module and / or a 5G module;

[0098] Step S102: When other modules in the communication device start up, determine the current remaining power that the external power supply in the communication device can provide according to the power consumption of the other modules, and determine the start mode of the cellular module and the power supply mode for the cellular module according to the current remaining power that the external power supply can provide and the power consumption parameters of the cellular module;

[0099] Among them, the power consumption parameters of the cellular module, such as the above-mentioned T2 and T3; the startup mode of the cellular module, such as the combination of the cellular module and the SIM card, determine the combination mode of the 4G module, 5G module and SIM1, SIM2. It is possible to start only one cellular module (such as 4G-SIM1), or to start two cellular modules (such as 4G-SIM1, 5G-SIM2).

[0100] By step S102, the startup mode of the cellular module and the power supply mode for the cellular module are determined, so as to realize stable and reliable transmission of the video stream, thereby avoiding serious problems such as insufficient power supply of the external power supply due to excessive power consumption of the cellular module.
