In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In this embodiment, a method for controlling power consumption of a camera is provided, and fig. 1 is a first flowchart of a method for controlling power consumption of a camera according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, acquiring a current power consumption value of a current execution task of the camera; the first power consumption value can be calculated by obtaining a current value and a voltage value for executing the first task, and the power consumption value of the actual operation of the camera device can also be detected by the power measuring instrument.
Step S104, acquiring the estimated power consumption value of the current request execution task of the camera; wherein, the task to be executed comprises: a fan control task, a holder control task, a sound control task and a light control task; the fan control task can be triggered by all requirements for starting the fan such as lens fogging, the cloud deck control task can be triggered by all requirements for controlling the rotation of the cloud deck such as a user manual control cloud deck or an event linkage cloud deck, the sound control task can be triggered by all requirements for playing sound such as user manual playing sound or event linkage sound, and the light control task can be triggered by all requirements for starting light such as user manual control light or detection picture too dark linkage light.
Step S106, accumulating the current power consumption value and the estimated power consumption value to obtain an estimated total power consumption value; under the condition that the estimated total power consumption value is larger than the power consumption threshold value of the camera equipment, comparing the priority of the current execution task and the priority of the current request execution task, and suspending the execution of the task with low priority to ensure that the actual total power consumption of the camera is smaller than or equal to the power consumption threshold value; for example, when the priority of the currently executing task is greater than the priority of the currently requested executing task, the currently executing task is executed and the currently requested executing task is delayed to be executed, or the currently executing task is executed and the power consumption value of the currently requested executing task is reduced until the estimated total power consumption value is less than or equal to the power consumption threshold value; in addition, the actual power consumption value of the camera device is updated according to the real-time execution status of the currently executed task and the currently requested execution task.
In the related art, the use functions of the camera device are controlled independently, the actual power consumption value is detected and the power consumption value of the task to be executed is evaluated through steps S102 to S106, and the actual operation of the executed task of the camera device is determined according to the priority or the operation time of the executed task under the condition that the sum of the current power consumption value and the expected power consumption value is larger than the power consumption threshold of the camera device, so that the problem that the instantaneous power consumption is large or the functions are limited in the use of the camera is solved, and the safety performance of the camera is improved.
In an embodiment, a method for controlling power consumption of a camera is provided, and fig. 2 is a second flowchart of a method for controlling power consumption of a camera according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step S202, according to a task priority list, acquiring the priority levels of the current execution task and the current request execution task, wherein the task priority list comprises the priority levels and the power consumption influence factors; the task priority list is shown in table 1; the task priority list can also comprise running time, and the running time of the currently executed task and the running time of the currently requested executed task are compared according to the task priority list;

Step S204, comparing the priority level, acquiring the actual total power consumption of the camera according to the power consumption influence factor, and suspending the execution of the task with low priority to ensure that the actual total power consumption of the camera is less than or equal to the power consumption threshold value; for example, when the currently executed task is a fan control task and the currently requested execution task is a sound control task and a light control task, the priority level of the currently executed task is determined to be the highest according to the priority level, the currently executed task is preferentially executed, the currently requested execution task is suspended from execution, or the currently requested execution task is executed after the power consumption value of the currently requested execution task is reduced.
Through the steps S202 to S204, when the total power consumption is expected to be greater than the power consumption threshold, the priority levels of the currently executed task and the currently requested execution task are obtained and compared according to the task priority list, so that the execution of each task is controlled according to the importance degree of each task, the power consumption influence factor, the running time and other factors, and the effect of jointly controlling the use function of the camera device in a specific scene is further optimized.

Step S304, in the case that the execution time is the first time period, the obtained expected power consumption value is the sum of the first power consumption value and the second power consumption value, and in the second time period, the obtained expected power consumption value is the sum of the third power consumption value and the fourth power consumption value.
Through the above steps S302 to S304, the expected power consumption value dynamically changes according to the change of the actual environment at different time periods, so that the power consumption of the camera device is reduced on the basis of jointly controlling the use functions of the camera device, and the effect of jointly controlling the use functions of the camera device in a specific scene is optimized.
