Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
The technical features of the different embodiments of the invention described below may be combined with one another as long as they do not conflict with one another.
The current quick charger in the market supports output modes of 9V-1A, 9V-1.5A, 9V-2A, 12V-1.5A and the like in a quick charging mode, and when a quick charging protocol is successfully identified between powered equipment and the quick charger, the quick charger outputs voltage in the quick charging mode.
In the prior art, the load power of a plurality of power receiving devices can be adjusted according to different working demands, for example, an electric fan can adjust the wind speed through a plurality of gears in the use process, the load power corresponding to different gears is different, and the characteristics of real-time adjustment and control of the load power of the power receiving devices in work are also available for electric devices such as air conditioners and electric heaters. For such powered devices that use the fast charger to perform power supply of the whole machine in the fast charging mode, if the load power is larger in the use process, the overload protection value of the fast charger is exceeded, namely when the fast charger detects that the output power exceeds the rated value, the fast charger can automatically cut off power supply output, after a period of time, the fast charger needs to perform fast charging protocol identification with the controller of the powered device again, and voltage output in the fast charging mode is performed after the identification is successful. If the output power exceeds the rated value again, the overload protection action is repeated all the time, the power receiving equipment is always in a circulating start-stop state, the normal work cannot be carried out, and the user experience is seriously affected.
Based on the above-mentioned problems, an embodiment of the present invention provides a method for controlling a powered device in a fast charging mode, which is applied to a powered device that uses a fast charging mode of a fast charger to supply power, where load power of the powered device is adjustable, as shown in fig. 1, and the method for controlling a powered device in the fast charging mode mainly includes the following steps:
step S101: the method comprises the steps of obtaining the current power supply voltage of the power receiving equipment or obtaining the current load power and the target load power of the current power supply voltage of the power receiving equipment. It should be noted that in the embodiment of the present invention, the power receiving device is taken as an example of a dc fan, and in practical application, the power receiving device may be any other electric appliance that uses a fast charging mode of a fast charger to supply power and has adjustable load power, for example: the invention is not limited to electric heaters, warm fans and other electrical equipment.
Specifically, since the quick charger has a characteristic that the output voltage gradually decreases with an increase in output power in the quick charging mode. Thus, it is possible to reflect whether the fast charger is in an overload state by monitoring the current supply voltage of the fan. Because the load of the fan is a motor, the load power condition of the fan can be intuitively reflected through the motor rotation speed, namely, the current load power can be represented by the current rotation speed of the fan, and the target load power is the motor rotation speed corresponding to the fan gear desired to be set by a user, for example: when the user selects the high wind speed gear, the target load power can be represented by the motor rotation speed corresponding to the high wind speed gear.
Step S102: and adjusting the current load power according to the relation between the current supply voltage and a preset overload voltage protection threshold. . Specifically, in order to avoid the situation that the overload of the quick charger stops supplying power due to the overlarge target load power set by a user, the current load power is gradually adjusted to the target load power until the current load power reaches the target load power or the current power supply voltage reaches a preset overload voltage protection threshold value, so that the use experience of the user is improved. The preset overload voltage protection threshold is set according to an output voltage value of the quick charger connected to the current powered device for executing an overload protection action, in practical application, the output voltage value of the quick charger for executing the overload protection action may be directly selected as the preset voltage protection threshold, or in order to avoid that the quick charger executes the overload protection action by mistake due to a measurement error or a delay, or that other execution actions for increasing load power may exist in the controlled electrical appliance, for example: the user sets the fan oscillating function to increase the load power, etc., so that the preset voltage protection threshold is set to be a voltage value larger than the output voltage value of the quick charger for performing the overload protection action, and the specific reserved voltage value can be flexibly adjusted according to the actual situation.
Specifically, in an embodiment, the step S102 specifically includes the following steps:
step S201: and judging whether the current power supply voltage reaches a preset overload voltage protection threshold. Specifically, in order to avoid the situation of the overload of the fast charger power, before the power receiving apparatus is adjusted to the target load power, it is required to determine whether the current power supply voltage of the power receiving apparatus reaches the preset overload voltage protection threshold. If the current supply voltage has been reduced to the preset overload voltage protection threshold, it indicates that the powered device cannot normally operate at the target load power in the fast charging mode, for example: the electric fan cannot be operated to the highest rotation speed gear set by the user, and step S204 is performed, otherwise step S202 is performed.
Step S202: and when the current power supply voltage is larger than a preset overload voltage protection threshold value, judging whether the current load power reaches the target load power or not. Specifically, taking the electric fan as an example, the current load power is adjusted, that is, the current rotation speed of the motor is adjusted, by judging whether the current rotation speed of the fan motor reaches the rotation speed of the motor corresponding to the target gear, if not, step S203 is executed, if the current rotation speed of the fan motor reaches the target gear, which indicates that the electric fan can normally work with the target gear set by the user in the fast charging mode, overload condition of the fast charger does not occur, and if the user changes the fan gear, step S101 is returned again.
Step S203: when the current load power does not reach the target load power, the current load power is increased, and the process returns to step S201. Specifically, the current load power can be increased according to the first preset load power adjustment threshold value, for example, in the process of adjusting the rotating speed of the fan to the target gear, a step-type speed adjusting method can be adopted to adjust the speed in a certain period, the rotating speed difference values (namely the first preset load power adjustment threshold value) which are set twice are the same and are close to the target rotating speed, so that stable conversion of the rotating speed is realized, the service life of the rotating speed motor is prolonged, the rotating speed change is stable, the use experience of a user can be improved, and meanwhile, the change condition of the current power supply voltage of the fan is detected in real time in the speed adjusting process. The first preset load power adjustment threshold may be set according to the response speed of the quick charger and the adjustment time of the powered device, which is not limited by the present invention. Currently, in practical application, the present invention is not limited to this, and the present invention may also be applied to increasing with a larger rotation speed value when the difference between the current load power and the target load power is larger, and increasing with a smaller rotation speed value when the difference is smaller.
Step S204: and when the current power supply voltage reaches a preset overload voltage protection threshold, reducing the current load power and maintaining the reduced current load power. Specifically, in order to leave a certain power margin, the gear (motor rotation speed) cannot be increased at this time, but in order to ensure that the functions available to the user in this state are as many as possible (for example, if the power margin is left sufficient, the user may also use the fan head-shaking function, etc.), so the current load power needs to be appropriately reduced to ensure that the remaining power margin is sufficient. In practical application, the current load power may be reduced according to a second preset load power threshold, where the second preset load power threshold may be set according to an actual power margin requirement, and the invention is not limited thereto. Of course, the current load power may be directly maintained without adjusting the current load power without considering the power margin, and the invention is not limited thereto.
Step S205: and when the current power supply voltage reaches a preset overload voltage protection threshold value and the current load power does not reach the target load power, generating alarm information. Specifically, if the current supply voltage has been lowered to the preset overload voltage protection threshold, but the current load power has not yet reached the target load power set by the user, an alarm message is generated to prompt the user that the rated output power of the quick charger selected by the user cannot completely match the requirement of the powered device, so that the user replaces the quick charger with a larger rated output power to match the powered device, or prompts the user to replace the working mode of the powered device, so as to meet the power output requirement of the quick charger, for example: the fan is changed from a high wind speed gear to a lower wind speed gear.
Specifically, in an embodiment, in order to avoid power failure of the device caused by occurrence of a power overload condition due to an excessive initial load power gear when the powered device is powered on, before executing the step S101, the method further includes the following steps:
step S103: a start signal of the powered device is acquired. Specifically, the start signal is an operation signal for a user to operate the powered device such as the electric fan to turn on. In practical application, when the user turns off the fan, the power supply may be turned off only, and the fan is in the high wind speed gear and is not reset before the user turns on the fan again, and if the user turns on the fan again, the fan will directly run in the high wind speed gear, so that the output power of the quick charger is smaller than the load power of the high wind speed gear, the power overload may occur directly, and the quick charger performs the overload protection action.
Step S104: and starting the powered device at a preset safe load power according to the starting signal. Specifically, the preset safe load power is set reasonably in advance according to the load power condition of the powered device and the overload protection output power of the quick charger, and when the powered device operates under the preset safe load power, the overload condition of the quick charger cannot occur, which is not limited by the present invention, for example: after the starting signal of the electric fan is monitored, the fan can be controlled to start to run for a certain time at the rotating speed of the lowest wind speed gear, for example, 2s and the like, the overload of the quick charger is not usually caused when the lowest fan runs, if the overload condition still occurs when the lowest fan runs at the gear, the carrying capacity of the quick charger cannot be matched with the fan, and a user can be directly reminded of replacing the quick charger.
Specifically, in another alternative embodiment, the step S102 specifically includes the following steps:
step S301: and calculating the difference value between the current power supply voltage and the preset overload voltage protection threshold value.
Step S302: and judging whether the difference value is smaller than a preset difference value threshold value or not.
Step S303: and when the difference value is smaller than a preset difference value threshold value, maintaining the current load power.
Specifically, in order to further avoid that the power supply voltage exceeds the overload voltage in the fast charging mode due to the delay of voltage detection, the operation reliability of the powered device is improved, the load power can be controlled by calculating and monitoring the difference between the current power supply voltage and a preset overload voltage protection threshold in real time, and the specific control mode is that once the difference between the current power supply voltage and the preset overload voltage protection threshold is monitored to be smaller than the preset difference threshold, the current load power is maintained, i.e. the current rotating speed is maintained unchanged, for example, the current operation state of the fan can be locked, a user performs speed-increasing gear-shifting again at the moment, and the controller does not respond to the instruction to avoid that the fan stops operating due to the fact that the user increases the gear.
By executing the steps, the method for controlling the powered device in the fast charging mode provided by the embodiment of the invention obtains the current power supply voltage of the powered device, or obtains the current power supply voltage, the current load power and the target load power of the powered device, and adjusts the current load power according to the relation between the current power supply voltage and the preset overload voltage protection threshold value, so that the problem that the powered device is frequently started and stopped due to the fact that the fast charger enters the overload protection action in the fast charging mode is avoided, the powered device can normally work in the fast charging mode, the user experience is improved, the device fault caused by the frequent start and stop of the powered device is avoided, and the service life of the powered device is prolonged.
A specific application example of the electric fan as the power receiving apparatus will be described below, in which the power receiving apparatus control method in the fast charging mode provided in the embodiment of the present invention is described in detail.
When the fan is powered by the fast charger in the fast charging mode, the working process of the fan is controlled by the controller in the fan as shown in fig. 2, and the input voltage (i.e. the current power supply voltage) provided by the fast charger is detected in real time by the controller in the whole control process.
When the fan is started, the fan is started at a low rotating speed for 2 seconds, so that the occurrence of power overload caused by overlarge initial gear when the fan motor is started is avoided. After the low-speed motor starts to run for 2 seconds, in the process of adjusting the speed of the fan to a target gear (namely target load power), step-type speed regulation (namely speed regulation is carried out in a certain period, the difference value of the speeds which are set twice is the same) is adopted, the normal target speed is close, the change condition of the input voltage of the fan controller is detected in real time in the speed regulation process, when the input voltage is reduced to a voltage threshold corresponding to overload protection of the quick charger, the speed is immediately stopped to be increased, and the speed is reduced appropriately, so that the purpose of limiting the load power is achieved, the output voltage value of the quick charger in a quick charging mode is ensured to be maintained in a state higher than the overload protection voltage threshold, and the quick charger is prevented from entering a protection state due to output overload. When the output voltage value of the quick charger in the quick charging mode is lower than the overload protection voltage threshold, the fan properly reduces the rotating speed to limit the load output power, and meanwhile, an alarm is given to prompt a user that the rated output power of the selected quick charger cannot be completely matched with the requirement of the whole machine, so that the user can replace the quick charger with larger rated output power to match the whole machine, or prompt the user to reduce the fan gear.
By executing the steps, the method for controlling the powered device in the fast charging mode provided by the embodiment of the invention obtains the current power supply voltage of the powered device, or obtains the current power supply voltage, the current load power and the target load power of the powered device, and adjusts the current load power according to the relation between the current power supply voltage and the preset overload voltage protection threshold value, so that the problem that the powered device is frequently started and stopped due to the fact that the fast charger enters the overload protection action in the fast charging mode is avoided, the powered device can normally work in the fast charging mode, the user experience is improved, the device fault caused by the frequent start and stop of the powered device is avoided, and the service life of the powered device is prolonged.
