The embodiment of the application provides a power adjustment method, a power adjustment device, computer equipment and a storage medium, and aims to solve the technical problem that an infrared camera is abnormally restarted during normal work. The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. It should be noted that, in the power adjustment method provided in the present application, the execution main bodies of fig. 2 to fig. 6 are computer devices, where the execution main body may also be a power adjustment apparatus, where the apparatus may be implemented as part or all of power adjustment by software, hardware, or a combination of software and hardware.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
in an embodiment, fig. 2 provides a power adjustment method, where the embodiment relates to a specific process in which a computer device executes a power reduction strategy when a total power of states to be converted of an image pickup device is greater than a maximum power limit of the image pickup device, based on an obtained maximum power limit of the image pickup device, as shown in fig. 2, the method includes:
S101, acquiring a maximum power limit value of the camera equipment; wherein the maximum power limit represents a maximum power value allowed to be increased when the image pickup apparatus is operating normally.
In this embodiment, the image capturing apparatus may be any image capturing apparatus, which is not limited in this embodiment, and may be, for example, an infrared camera or the like. The maximum power limit of the image pickup apparatus represents a maximum power value allowed to be increased when the image pickup apparatus normally operates, that is, a maximum value of a sum of powers of all modules to be turned on that can be borne by the image pickup apparatus. Taking the example that the image pickup apparatus is an infrared camera, the infrared camera includes a core module and a peripheral power module on a circuit, wherein the core module may be, for example, a main chip, an image sensor, etc., and the peripheral power module may be, for example, an infrared lamp, an electric lens, an ICR, an electric heater, etc., then the maximum power limit value of the infrared camera represents a value of total power increase of the core module and the peripheral power module in an allowable operating state of the infrared camera in the current environment. For example, in practical application, the mode of obtaining the maximum power limit of the image capturing device by the computer device may be to obtain the maximum power limit by testing in a mode of building an analog circuit, or may be to input a pre-recorded parameter of the image capturing device into a pre-trained neural network to obtain the maximum power limit, or may be in other modes, which is not limited in this embodiment.
and S102, judging whether the total power of the to-be-converted state of the camera equipment is larger than the maximum power limit value.
in this step, based on the maximum power limit of the image capturing apparatus obtained in the step S101, the computer apparatus determines whether the total power of the states to be converted of the image capturing apparatus is greater than the maximum power limit, where the total power of the states to be converted of the image capturing apparatus indicates the total power of all modules to be started of the image capturing apparatus when the image capturing apparatus is about to be converted into a certain state, the state to be converted may be any state, and the embodiment of the power module started in any state is not limited. In practical application, as shown in fig. 2a, the computer device obtains the total power of all modules that need to be started in the state that the image capturing apparatus is about to be switched, compares the total power of all modules that need to be started with the maximum power limit of the image capturing apparatus in step S101, and determines whether the total power of all modules that need to be started is greater than the maximum power limit of the image capturing apparatus.
S103, if the total power of the states to be converted of the camera equipment is larger than the maximum power limit value, a power reduction strategy is executed; wherein the power reduction strategy is used for reducing the total power of the states to be converted of the image pickup device.
based on the determination in the step S102, if the determination result is that the total power of the to-be-converted state of the image pickup apparatus is greater than the maximum power limit value of the image pickup apparatus, continuing as shown in fig. 2a, the power reduction policy is started to be executed, otherwise, the power reduction policy is not executed. Wherein the power reduction strategy is used for reducing the total power of the states to be converted of the image pickup device. For example, the power reduction policy may be a preset sequence for turning off each peripheral power module to be started, and in practical application, when detecting that the total power of the state to be converted of the image pickup apparatus is greater than the maximum power limit value, the computer apparatus may turn off each module according to the preset sequence for turning off each power module to be started until the total power of the power modules to be started of the image pickup apparatus is less than the maximum power limit value, so as to ensure that the image pickup apparatus operates normally.
In the power adjustment method provided by this embodiment, the computer device compares the power sum of the modules to be turned on in the state to be converted of the camera device with the maximum power limit of the camera device in the current environment, and executes a power reduction strategy to ensure that the camera device can normally operate if the power sum of the state to be converted of the camera device is greater than the maximum power limit of the camera device.
On the basis of the above embodiment, an embodiment of the present application further provides a power adjustment method, which relates to a specific process in which a computer device determines a maximum power limit value of an image pickup device according to parameters of the image pickup device when an infrared module is at different current values, as shown in fig. 3, the image pickup device only includes the infrared module; acquiring a maximum power limit of the image pickup apparatus, wherein the step S102 includes:
s201, acquiring a power value and an input voltage value of the image pickup device when the infrared module has different current values.
in this embodiment, the computer device obtains the power value and the input voltage value of the imaging device when the infrared module has different current values. For example, taking the circuit model diagram of the infrared camera power supply shown in fig. 3a as an example, the power supply voltage Vp reaches the infrared camera through the cable, and the input voltage Vd is lowered to Vp due to the cable impedance Rc. The infrared camera is internally composed of a core module Rd and an external power module, wherein the external power module is composed of an infrared module Rir and a plurality of power modules R1, R2 and R3 … … Rn. The power consumption P of the whole infrared camera is defined, the power consumption of the external power module is PRIr, PR1, PR2 and PR3 … … PRn in sequence, and the current I on the power supply loop is defined. There is the following equation:
Then the correspondence is available:
Based on this, when the computer device obtains the power value and the input voltage value of the image pickup device at different current values of the infrared module, the power value and the input voltage value of the image pickup device may be obtained by turning off the infrared module and other power modules, detecting the input voltage value Vd1 of the current image pickup device, defining the total power of the current image pickup device as P1, then turning on the infrared module, setting the current of the infrared module to 10% brightness, that is, the infrared power as 10% PRir, detecting the input voltage value Vd2 of the current image pickup device, defining the total power of the current image pickup device as P2, finally setting the current of the infrared module to 20% brightness, that is, the infrared power as 20% PRir, detecting the input voltage value Vd3 of the current image pickup device, defining the total power of the current image pickup device as P3,
And S202, determining a power supply voltage value and a cable impedance value of the image pickup device according to the power value and the input voltage value of the image pickup device.
Based on the power value and the input voltage value of the image pickup apparatus when the infrared module is at different current values acquired in the above step S201, the computer apparatus determines the power supply voltage value and the cable impedance value of the image pickup apparatus. Illustratively, still taking fig. 2a as an example, based on the above-noted values of power and input voltage, the equation can be derived:
since in this equation P2-P1 and P3-P1 are 10% luminance 10% power PRir and 20% luminance power 20% PRir of infrared lamps, the power values of which have been recorded in advance by the software are known quantities; vd1, Vd2, Vd3 are input voltage values detected in real time and are also known quantities. A solution of the unknown quantities of supply voltage Vp and cable impedance Rc can be obtained:
And S203, determining the maximum power limit value of the image pickup equipment according to the power supply voltage value of the image pickup equipment and the cable impedance value.
in this step, the computer device determines the maximum power limit value of the image pickup device according to the power supply voltage value of the image pickup device and the cable impedance value in the above step S202. For example, with reference to fig. 2a, assuming that the lowest input voltage allowed by the normal operation of the infrared camera is Vdmin, the power of the corresponding infrared camera at this time is defined as Pmax, and the infrared camera in this state is set to allow the total power of the infrared module and other power modules to increase by Δ Pmax. From the Vp, Rc calculated above, the Vd1 measured when the infrared and other power modules are both off, and the predetermined Vdmin, the value of Δ Pmax can be calculated by the following equation.
In the power adjustment method provided by this embodiment, the computer device records different parameters, that is, power values or input voltage values, of the camera device when acquiring different currents according to the infrared module, and calculates the power supply voltage and the cable impedance of the camera device according to the parameters, thereby determining the maximum power limit value allowed to be increased by the camera device.
the specific process of executing the power reduction strategy by the computer device when the total power of the to-be-converted state of the image capturing device is greater than the maximum power limit value will be described by several embodiments below.
In an embodiment, as shown in fig. 4, an embodiment of the present application provides a power adjustment method, where the image pickup apparatus includes an infrared module and a peripheral module other than the infrared module, and S103 includes:
s301, acquiring the priority sequence of the infrared module and the priority sequence of the peripheral module; the priority of the current minimum limit value of the infrared module is greater than the priority of the current maximum limit value of the infrared module.
In this embodiment, the computer device obtains a priority order of the infrared module and a priority order of the peripheral module, where the priority order of the infrared module and the priority order of the peripheral module are predefined and stored orders, and the priority order of the infrared module includes a priority that a priority of a current minimum limit of the infrared module is greater than a priority of a current maximum limit of the infrared module, that is, the priority order of the infrared module is gradually decreased in an order of current from small to large. The priority order of the peripheral modules means the order of priority of modules other than the infrared module, which is determined according to the actual situation since the peripheral modules included in the image pickup apparatus are different in number and kind according to the actual situation.
and S302, reducing the total power of the states to be converted of the camera equipment according to the priority sequence of the infrared modules and the priority sequence of the peripheral modules.
In this step, based on the priority order of the infrared module and the priority order of the peripheral module obtained in step S301, the computer device reduces the total power of the state to be converted of the image capturing apparatus, that is, starts to execute the power reduction policy, and it can be understood that the computer device preferentially ensures that the module with the high priority normally operates in the power reduction process.
As for the computer device reducing the total power of the states to be converted of the image capturing device according to the priority order of the infrared modules and the priority order of the peripheral modules, an embodiment of the present application further provides a power adjustment method, as shown in fig. 5, then the foregoing S302 includes:
s401, if the current of the infrared module is the maximum current limit, whether the total power of the state to be converted of the camera device is larger than the maximum power limit is judged.
In this embodiment, as shown in fig. 5a, the computer device first determines whether the total power of the state to be converted of the image capturing device is greater than the maximum power limit when the current of the infrared module is equal to the maximum current limit, that is, in this step, when the computer device obtains the maximum power of the infrared module, the image capturing device is to turn on the total power of all modules, and then determines whether the total power of the state to be converted is lower than the maximum power value allowed to be increased when the image capturing device normally operates.
s402, if the total power of the state to be converted of the camera equipment is larger than the maximum power limit value, whether the state to be converted of the camera equipment comprises the step of starting an infrared module is detected, and a detection result is obtained.
based on the determination result in the step S401, referring to fig. 5a, if the total power of the states to be converted of the image pickup apparatus is greater than the maximum power limit value, the computer apparatus continues to detect whether the state to be converted of the image pickup apparatus includes turning on the infrared module, so as to obtain a detection result, where the detection result is that the infrared module is turned on or the infrared module is not turned on.
And S403, reducing the total power of the states to be converted of the image pickup equipment according to the detection result.
Based on the detection result in the step S402, the computer device reduces the total power of the states to be switched of the image capturing apparatus, and optionally, the manner for the computer device to reduce the total power of the states to be switched of the image capturing apparatus according to the detection result includes two schemes:
in the scheme A, if the infrared module is started according to the detection result, the total power of the camera equipment in the state to be converted is reduced according to the size relation between the total power of the camera equipment in the state to be converted and the maximum power limit value when the current of the infrared module is the current minimum limit value.
in this scheme, if the detection result is that the infrared module is turned on, the computer device obtains the total power of the state to be converted of the image capturing device when the current of the infrared module is the current minimum limit value, and based on the total power in the state, the computer device compares the size relationship between the total power of the state to be converted of the image capturing device and the maximum power limit value when the current of the infrared module is the current minimum limit value, please refer to fig. 5a, and reduce the total power of the state to be converted of the image capturing device according to the size relationship. If the computer device reduces the total power of the states to be converted of the image capturing device according to the size relationship, optionally, the scheme a includes:
in the scheme a1, if the total power of the states to be converted of the image pickup apparatus is greater than or equal to the maximum power limit when the current of the infrared module is the minimum limit, it is determined that the current value of the infrared module is the minimum limit of the current of the infrared module, and the total power of the states to be converted of the image pickup apparatus is reduced according to the priority order of the peripheral modules.
the scheme is that when the current of the infrared module is the minimum limit value, the total power of the states to be converted of the camera equipment is greater than or equal to the maximum power limit value, it means that in this case, the image capturing apparatus needs to start the infrared module, but the power of the minimum current value of the infrared module exceeds the maximum power limit of the image capturing apparatus, please continue to refer to fig. 5a, the computer device determines that the current value of the infrared module is the current minimum limit value of the infrared module, that is, allows the infrared module to be turned on in the minimum current state, and, at the same time, since the total power of the states to be converted of the image pickup apparatus in this state is still larger than the maximum power limit, in order to ensure that the image pickup apparatus operates normally, the computer device continues to decrease the total power of the states to be switched of the image pickup device according to the priority order of the peripheral modules until the total power of the states to be switched of the image pickup device is equal to the maximum power value allowed to be increased when the image pickup device is operating normally.
in the scheme A2, if the total power of the states to be converted of the camera device is smaller than the maximum power limit when the current of the infrared module is the minimum limit, determining that the current value of the infrared module is greater than or equal to the minimum limit of the current of the infrared module and less than or equal to the current peak value of the infrared module; the current peak value of the infrared module represents a current value corresponding to the infrared module when the total power of the states to be converted of the camera equipment is equal to the maximum power limit value.
in the scheme, when the current of the infrared module is the minimum limit value, the total power of the states to be converted of the camera device is smaller than the maximum power limit value, which means that the camera device needs to start the infrared module under the condition, but the power of the infrared module with the minimum current value does not have the maximum power limit value of the camera device, that is, the current of the infrared module allowed by the current voltage is a current value higher than the minimum value, please refer to fig. 5a continuously, the computer device needs to determine an infrared module current peak value, which means that the current value corresponding to the infrared module when the total power of the states to be converted of the camera device is equal to the maximum power limit value, and is equivalent to that the current value of the infrared module is greater than or equal to the infrared module current minimum limit value and less than or.
and in the scheme B, if the infrared module is not started according to the detection result, the total power of the states to be converted of the camera equipment is reduced according to the priority sequence of the peripheral modules.
In the present embodiment, as shown in fig. 5a, for example, if the camera device does not need to start the infrared module in practical application, the computer device first obtains the priority order of the peripheral modules, and then reduces the total power of the camera device in the state to be converted according to the order, so as to ensure the normal operation of the camera device.
In one embodiment, as shown in fig. 6, the present application provides a power adjustment method, where the "reducing the total power of the states to be converted of the infrared camera according to the priority order of the peripheral modules" in the steps of the above-mentioned schemes B and S302 includes:
S501, judging whether the number of the peripheral modules in the state of waiting conversion of the image pickup device is larger than 0.
