Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the application provides a multi-path power supply control method which can be applied to a power supply controller in a multi-path power supply system. Fig. 1 is a schematic structural diagram of a multi-path power supply system according to an embodiment of the present disclosure. The multi-path power supply system can comprise a storage battery, a commercial power supply, green energy equipment, a power supply controller and intelligent equipment.
Wherein, green energy equipment can be with green energy conversion electric energy to the storage is in the battery. In one example, the green energy device may include a solar energy device and an air energy device. The solar energy equipment can convert solar energy into electric energy and store the electric energy in the storage battery, and the air energy equipment can convert air energy into electric energy and store the electric energy in the storage battery, and can also be wind energy equipment and the like.
The storage battery and the commercial power are used for providing electric energy for the intelligent equipment.
The power supply controller is connected with the intelligent equipment and the storage battery respectively, and can control whether the power supply mode of the intelligent equipment is supplied by the storage battery or the household 220V stable power supply according to the residual capacity of the storage battery and the power utilization condition of the intelligent equipment. In one example, a power supply controller may include a control module and a switching module. The input end of the control module is connected with the storage battery and the intelligent device and used for collecting the working electric energy value of the intelligent device and the residual electric energy value of the storage battery and calculating whether to switch the commercial power and the time for switching the commercial power according to the residual electric energy value and the working electric energy value of the intelligent device. The switching module is used for switching between the storage battery and a household 20V stable power supply. The switching module and the control module may be two separate devices, or may be an integrated device integrated into a whole, and herein, the hardware form of the switching module and the control module is not limited.
A detailed description will be given below, with reference to a specific embodiment, of a multi-path power supply control method provided in an embodiment of the present application, where the method is applied to a power supply controller in the multi-path power supply control system, and a power supply manner of an intelligent device includes battery power supply and mains power supply, as shown in fig. 2, the method includes the following specific steps:
s201: and when the intelligent equipment starts to work, controlling the power supply mode of the intelligent equipment to be a storage battery.
In the embodiment of the application, once the intelligent device starts to work, the intelligent controller firstly controls the power supply mode to supply power to the storage battery. Because the storage battery is energy-saving, the preferred power supply mode of the intelligent equipment is to use the storage battery for power supply.
In one example, the smart device may be a smart home product such as a smart mattress. The intelligent mattress has the functions of heating, massaging and the like. Almost 8 hours of people pass through the bed in one day, so the working time of the intelligent mattress is almost 8 hours. The power consumption is still very high, which leads to increased household costs. Therefore, it is necessary to use a multi-channel power supply system consisting of green energy and commercial power to supply power, so as to achieve the purpose of energy saving.
S202: and calculating a target electric energy value required by the intelligent equipment within a preset working time.
In the embodiment of the application, after the intelligent device starts a certain work, a work duration is set for the work, and the intelligent controller needs to calculate the total electric energy value required by the intelligent device to execute the work within the preset work duration.
Optionally, in this embodiment, the calculating the target electric energy value required by the intelligent device within the preset operating time period may be: acquiring the current working power and preset working time of the intelligent equipment; and calculating the electric energy value required by the intelligent equipment in the preset working time according to the power and the preset working time.
The current power of the intelligent device is the power of the intelligent device in the current working mode, and the power of the intelligent device is different in different working modes. For example, a smart mattress includes a heating mode of operation, which requires approximately 80W of power, and a massaging mode of operation, which requires approximately 50W of power.
In addition, the preset working duration is the working duration of the intelligent device in a certain working mode set by a user. The preset working time lengths corresponding to different working modes are also different. For example, in the massage mode, the user may set a duration of 2h or more, but in the heating mode, a maximum of 1h may be set to reach a very high temperature, which may cause fire and other problems if heating is continued.
After the power supply controller obtains the current working power and the preset working time of the intelligent equipment, the power supply controller multiplies the current working power and the preset working time to obtain the electric energy value required by the intelligent equipment.
Specifically, the target electric energy value is a total electric energy value required for the intelligent device to operate within a preset operation time period.
In one example, taking the intelligent mattress as an example, assuming that the intelligent mattress is turned on to heat, and the heating time set by the user is 1 hour, the intelligent controller calculates the electric energy consumed by the intelligent mattress within the 1 hour, and multiplies the heating power and the heating time to calculate the electric energy required by the intelligent mattress to heat for 1 hour.
S203: and comparing the target electric energy value with the current residual electric energy value of the storage battery.
In the embodiment of the application, the power supply controller acquires the current residual capacity condition from the storage battery, and then compares the target electric energy value calculated in the previous step with the current residual electric energy value of the storage battery to judge whether the residual electric energy value in the storage battery can supply the total electric energy value required by the intelligent device to perform a certain work (such as heating an intelligent mattress). If the residual electric energy value in the storage battery is larger than the target electric energy value, the residual electric energy value in the storage battery can supply the electric energy value required by the intelligent equipment to execute a certain work, and the subsequent steps are not carried out.
S204: and if the residual electric energy value is smaller than the target electric energy value, calculating the actual working time of the residual electric energy value for the intelligent equipment to work.
In the embodiment of the application, if the residual electric energy value in the storage battery is smaller than the target electric energy value, the situation that the residual electric energy value in the storage battery can not support the intelligent device to perform the whole work is shown. Then the power supply controller is required to calculate the actual operating time of the intelligent device that can be supplied with the remaining electric energy in the battery.
In this embodiment of the application, the process of calculating the actual operating time of the smart device may be that the actual operating time of the smart device is obtained by dividing the remaining electric energy value in the battery by the power of the smart device when performing a certain operation.
In one example, the smart device is a smart mattress, and the work performed is heating, the heating power is 80W, the remaining electric energy in the battery is 60Wh, and the actual work time is 0.75 h.
S205: when the actual working time is long, the power supply mode of the intelligent equipment is switched from the storage battery to the commercial power.
In this embodiment of the application, after the actual working time is calculated in step S204, timing may be started by a timer inside the intelligent controller, where the timing time is the actual working time, and when the timing is finished, the power supply mode of the intelligent device is switched from the storage battery to the commercial power.
By the method, when the residual electric energy value in the storage battery cannot meet the requirement of the whole work of the intelligent equipment, the residual electric energy value is not directly switched to the mains supply, but the residual electric energy value is calculated firstly and can be used for the actual working time of the intelligent equipment, and the residual electric energy value in the storage battery is switched to the mains supply after being fully utilized, so that the utilization rate of the storage battery is increased, and the energy-saving effect is better.
Optionally, in this embodiment of the application, if none of the remaining power values in the battery can satisfy the minimum power threshold for the intelligent device to operate a certain work when the intelligent device performs the work, which indicates that none of the power values in the battery can start the work to be performed by the intelligent device, it is not necessary to perform steps S202-S205, and the battery is directly switched to the utility power to satisfy the work requirement of the intelligent device. The specific process is as follows: acquiring a preset lowest electric energy threshold value of the intelligent equipment; comparing the current residual electric energy value of the storage battery with the lowest electric energy threshold value; if the residual electric energy value is larger than the minimum electric energy threshold value, executing the steps S202-S205; otherwise, the power supply mode of the intelligent equipment is switched from the storage battery to the commercial power.
In the embodiment of the application, the lowest power threshold is a starting power value of the intelligent device for executing certain work, and if the starting power value is not reached, the intelligent device cannot be started.
Optionally, in this embodiment of the present application, when the power supply controller calculates that the actual operating time of the smart device is very short, and the smart device can only operate for a few minutes or even a few seconds, it is not necessary to count the time, and it is necessary to switch to the commercial power immediately. Therefore, the situation that the work of the intelligent equipment is influenced because the working time is too short and the commercial power is not switched in time is avoided. Therefore, when calculating the actual operating time, it is necessary to compare the actual operating time with the preset switching time. The specific process is as follows: comparing the actual working time length with a preset switching time length; if the actual working time is longer than the preset switching time, executing step S205; otherwise, the power supply mode of the intelligent equipment is switched from the storage battery to the commercial power.
In the embodiment of the present application, the preset switching duration refers to the minimum working duration after the intelligent device starts a certain working mode, and if the calculated actual working duration is less than the minimum working duration, the normal operation of the intelligent device cannot be guaranteed.
The above embodiment is a specific working implementation mode in the case that the storage battery is only used for supplying power, if the storage battery is used for supplying power and charging at the same time, the storage battery is not switched to the commercial power immediately when the actual working time is reached, and at this time, some electric energy values are charged into the storage battery, and it is to be continuously judged that the electric energy value charged later in the storage battery can meet the requirement of the intelligent device in the remaining working time.
Optionally, as shown in fig. 3, the specific operation process of the power supply controller may further include the following steps:
s301: under the condition that the storage battery supplies power and charges at the same time, when the actual working time length is reached, the residual target electric energy value required in the residual working time length of the intelligent equipment is calculated.
In the embodiment of the present application, the remaining operating time is the sum of the preset operating time minus the actual operating time of the smart device. If this step is performed for the first time, the actual operating time calculated for the first time is subtracted. If this step is performed a second time, the subtraction of the first calculated actual operation time period and the second calculated actual operation time period is the remaining operation time period. And then multiplying the power of the intelligent equipment for executing the work by the residual work time length to obtain a residual target electric energy value.
S302: and comparing the residual target electric energy value with the current residual electric energy value of the storage battery.
In the embodiment of the application, the current residual electric energy value of the storage battery is obtained again, and then the current residual electric energy value of the storage battery is compared with the residual target electric energy value. The working requirement of the intelligent device in the remaining working time can be met by judging the later charged electric quantity in the storage battery. If the later charged electric energy value in the storage battery is larger than the residual target electric energy value, which indicates that the operation requirement of the intelligent device in the residual operation time period can be met, the subsequent steps are not required to be executed.
S303: and if the current residual electric energy value of the storage battery is smaller than the residual target electric energy value, recalculating the actual working time of the residual electric energy value for the intelligent equipment to work.
In the embodiment of the application, if the later charged electric energy value of the storage battery is smaller than the residual target electric energy value, the situation that the electric energy requirement in the residual working time of the intelligent device cannot be met is indicated. The later charged energy value of the battery, i.e. the actual operating time of the battery for the intelligent device to operate within the remaining operating time, is recalculated. The calculation process may be: and dividing the current residual electric energy value in the storage battery by the power of the intelligent device for executing the current work to obtain the actual working time of the intelligent device in the residual working time.
S304: and comparing the actual working time length with the preset switching time length.
In the embodiment of the present application, after the actual operating time of the smart device in the remaining operating time is calculated, the actual operating time of the smart device is compared with the preset switching time, so as to avoid that when the actual operating time of the smart device calculated by the power supply controller is very small and only can be used for the smart device to operate for several minutes or even several seconds, the time is necessarily counted, and the smart device needs to be switched to the commercial power immediately. Therefore, the situation that the work of the intelligent equipment is influenced because the working time is too short and the commercial power is not switched in time is avoided.
S305: and if the actual working time length is longer than the preset switching time length, executing the step of calculating the residual target electric energy value required in the residual working time length of the intelligent equipment and the subsequent steps when the actual working time length is reached.
In the embodiment of the application, if the actual operating time of the intelligent device is longer than the preset switching time, which indicates that the electric energy charged later in the battery can meet the normal operation of the intelligent device within a certain time, a timer inside the power supply controller may be used to start timing, the timing time is the actual operating time, and after the timing is finished, the steps S301 to S304 are repeatedly executed.
S306: otherwise, the operation of switching the power supply mode of the smart device from the storage battery to the commercial power in step S205 is performed.
In this application embodiment, if the actual operating duration of smart machine is less than or equal to and predetermines to switch for a long time, it explains that the actual operating duration is the undersize, only can supply the smart machine to work for several minutes or even several seconds 'time, for preventing because operating duration is too short, come too late to switch the commercial power, influence smart machine's work, need be switched into the commercial power by the battery immediately.
Optionally, in this embodiment of the present application, in step 205, after the actual operating time period is reached, the method may further include obtaining a remaining battery energy value, and after obtaining the remaining battery energy value, the method may further include: if the current residual electric energy value of the storage battery is larger than the lowest electric energy threshold value of the intelligent equipment, executing the step of calculating the residual target electric energy value required in the residual working time of the intelligent equipment; otherwise, the step of switching the power supply mode of the intelligent equipment from the storage battery to the commercial power is executed.
The power supply controller can selectively control the charging mode of the storage battery under the condition that the storage battery supplies power and charges simultaneously. Specifically, environmental data can be gathered through external environment monitoring sensor etc. and according to environmental data decision which kind of green energy adopted charges. In one example, the battery is charged by a solar power device and an air power device, and the external environment monitoring sensor is an integrated sensor module for detecting an environment. For example, whether the current time is day is judged through a light sensor, if the current time is day, the solar energy device is selected for charging, and if the current time is night, the air energy device is adopted for charging. Whether it rains is judged through the raindrop sensor, if it rains, the solar equipment is selected to be charged, and if it does not rain, the air energy equipment is adopted to be charged. Whether sunlight is sufficient or not is judged by the aid of the temperature sensor, and whether the current requirement for using air energy equipment is met or not is judged by the aid of the air flow sensor.
