Referring to fig. 2, an embodiment of the present invention provides an electrical device control method, where the electrical device control method includes:
step S10, acquiring the current total current of the electricity environment of the electricity equipment;
in this embodiment, the electric device may be a household appliance such as an air conditioner, a refrigerator, a washing machine, and a range hood, or an office appliance such as a printer and a copier. The defined electric equipment is different according to different scenes, wherein the scenes comprise a family scene, an office scene, a business scene (a market, a supermarket and the like) and the like. The electricity utilization environment of the household appliance comprises a home environment, an office environment, a market environment and the like.
The total current of the electricity utilization environment of the electric equipment is obtained, wherein the electricity utilization environment is a household electricity utilization environment as an example, and the electric equipment is an air conditioner. Controlling the power equipment to be started based on the received power equipment starting instruction; after the useful electric equipment is started, the total current of the current household electricity is confirmed. In practical application, the household electricity is set by taking power as a unit, and the total current of the household electricity is calculated based on the detected total power of the household electricity. The method for converting the total power into the total current of the household power consumption is an existing current calculation formula, and is not described herein. Further, the step of obtaining the current total current of the household power comprises: and acquiring the real-time total power of the current household power, and calculating the current total current of the current household power according to the real-time total power.
When the total household electricity current is obtained, the specific scheme is that the total household electricity current is obtained, then the real-time voltage, the power factor and the like are obtained, then the power is converted into the total household electricity current through calculation, and the air conditioner is controlled through the total household electricity current and the specification of the household circuit on-off device. The total real-time power of the household can be apparent power, and can also be active power or reactive power. The specific confirmation is as follows:
1) total power being apparent power
And acquiring a voltage value in real time, wherein the current value is apparent power/voltage.
2) Total power is active power
And acquiring a voltage value and a power factor in real time, wherein the current value is active power/power factor/voltage.
3) The total power is reactive power
And acquiring a voltage value and a power factor in real time, wherein the current value is reactive power/(1-power factor)/voltage.
The current total current is the sum of the operating currents of all the electrical appliances in the total circuit loop of the electricity environment in which the electrical appliances are located during the operation of the electrical appliances, for example, three electrical appliances, namely, an electrical appliance, a refrigerator and a television, are connected in the circuit of the total current of the electricity environment in which the electrical appliances are located, wherein the current operating current of the electrical appliances is I1, the current operating current of the refrigerator is I2, and the current operating current of the television is I3, and the current total current value of the electricity environment in which the air conditioner is located is I1+ I2+ I3.
Step S20, when the current total current is in a preset interval, determining the on-off time of the circuit on-off device according to the total current;
setting a current interval in advance, setting a rated current value according to the characteristics of the current on-off device by using a current threshold value in the set current interval, and respectively setting current intervals based on the rated current value according to the rated current value, wherein the related current interval setting can refer to fig. 6, fig. 6 is the set household electricity current interval, and each current interval forms different current intervals by using a current value definition critical value. For example, in fig. 6, a is defined as an immediate shutdown area; BC are all defined as a frequency reduction area; d is defined as a hold frequency region; e is defined as the normal operating region. In addition, the critical value is a rated home current cut-off value set based on the current circuit switching device characteristic. As shown in fig. 6, a rated current value d0 is defined, which may be 40A or 50A or the like, depending on the configuration of the circuit switching device. A frequency holding area is arranged below the rated value of the device, and a fast frequency reduction area, a slow frequency reduction area and an immediate shutdown area are arranged above the rated value. As shown in fig. 6, the lower limit value dk of the frequency holding range is multiplied by a factor smaller than 1, for example, 0.92, based on the rated value d 0.
Or, when the current interval is set, another scheme is designed according to the minimum required current value of the operation of the electric equipment and the rated value of the household circuit on-off device. Assuming that the minimum operable current value of the electric equipment is I0, dk can be set to d 0-I0; furthermore, the method is determined according to the current value required by the lowest refrigeration capacity of the bearable electric equipment and the rated value of the household circuit on-off device. Assuming that the lowest cooling capacity of the sustainable air conditioner requires I1, dk may be set to d 0-I1. The upper limit value d1 of the slow down frequency region is determined according to the international standards of the air conditioner, and at present, the same international standard is adopted by most countries in the world. For example, if the international standard specifies that the circuit breaker 1h cannot be turned off at 1.13 times the rated current, d1 may be d1 ═ d0 × k1, and k1 may be 1.13 or may be a value close to 1.13. The upper limit value d2 of the fast frequency-reducing region is a certain value greater than the lower limit value d1, and d2 may be d2 — d0 × k 2. If the national standard stipulates that a current of 1.45 times must be switched off in the circuit switching device 1h, it is usual for k2 to take a value between d1 and 1.45, but values of 1.45 or more are not excluded.
And confirming the current interval where the current total current is calculated based on the set current interval, specifically, confirming the current interval where the current total current is based on the current total current for domestic electricity by comparing the total current for domestic electricity with a critical value of the current interval. When the determined current interval is a preset interval, determining the on-off time of the circuit on-off device according to the total current, wherein the preset interval is an A current area or a B current area; any one of the areas a-C, collectively referred to as the intelligent snap-off area, or a combination thereof, may be used.
The total current and the on-off time have a conversion relationship, for example, a conversion coefficient s from the total current to the on-off time is set according to the experimental result and the characteristics of the circuit switching device, and for example, the total current is I, the on-off time is t, the conversion coefficient s is I t 20, or I t 30, and the time unit is minute and is different according to the set conversion coefficient. The on-off time is the time for which the circuit breaking device delays to be opened, and if the on-off time is reached, the circuit breaking device is opened, and if the circuit breaking device is caused to open in the meantime
And step S30, determining the control parameters of the electric equipment according to the on-off time, and controlling the operation of the electric equipment according to the control parameters.
After the on-off time is obtained through calculation, determining control parameters of the electric equipment according to the on-off time, wherein different on-off times correspond to different electric equipment control parameters, and the longer the on-off time is, the larger the difference between the current total current and the set rated current of the circuit on-off device is, the more difficult the circuit on-off device is to be switched off; the shorter the on-off time is, the smaller the difference of the current rated current reaching the set current of the current on-off circuit device is, and the circuit on-off device is easy to be switched off. And judging whether the circuit on-off device is disconnected according to the on-off time to obtain the control parameter of the electric equipment to control the operation of the electric equipment, so that the circuit on-off device is prevented from being directly disconnected, and the whole power utilization environment is powered off.
Specifically, the step of determining the control parameter of the electric equipment according to the on-off time and controlling the operation of the electric equipment according to the control parameter includes: when the on-off time is less than the preset time, controlling the electric equipment to stop running; and when the on-off time is longer than the preset time, controlling the electric equipment to reduce the frequency for operation. And in order to better control the on-off of the on-off device of the control circuit, when the on-off time is longer than the preset time, calculating the difference between the on-off time and the preset time, and when the difference is smaller than the preset value, for example, the preset difference is 1 minute or 30s, increasing the frequency reduction speed and rapidly reducing the frequency.
In one embodiment, referring to fig. 3, controlling the powered device to operate at a reduced frequency comprises:
step S31, acquiring the time interval of the current total current of the electricity environment of the electric equipment detected twice before and after;
step S32, calculating the operating frequency of the electric equipment according to the current operating frequency, the time interval and the on-off time;
and step S33, controlling the electric equipment to reduce to the operation frequency for operation.
Corresponding relations are set among the current operating frequency, the time interval, the on-off time and the operating frequency, the operating frequency is directly calculated according to the corresponding relations, and the operation of the electric equipment is controlled according to the directly calculated operating frequency. And calculating a coefficient m according to the corresponding relation, converting the time interval and the on-off time into a frequency unit according to the coefficient m, and calculating according to the current operation frequency to obtain the frequency which needs to be operated finally.
In an embodiment, the formula for calculating the operating frequency of the electrical device according to the time interval and the on-off time is as follows:
f0-k2 f0 Δ t/t, wherein f0 is the current operating frequency, k2 is a coefficient, Δ t is the time interval for detecting the total household current, and t is the tripping time. k2 is set in advance for a constant. The running frequency is calculated through the on-off time, so that the running of the electric equipment can be accurately controlled, and the circuit on-off device is prevented from being disconnected.
In another embodiment of the present invention, referring to fig. 4, the controlling the power consuming device to operate at a reduced frequency includes:
step S34, determining the frequency reduction rate of the electric equipment according to the total current;
and step S35, controlling the electric equipment to reduce frequency to operate according to the frequency reduction rate.
The total current of the electricity environment where different electric equipment is located can correspond to different frequency reduction rates, and the frequency reduction rate of the corresponding electric equipment can be determined according to the obtained current total current through modes such as formulas, table look-up and the like. The down-conversion rate of the electric equipment corresponding to the current total current is larger as the current total current of the electric equipment is larger. Specifically, the frequency reduction rate of the electric equipment can be calculated according to the magnitude of the current total current and a fitting formula between a pre-established total current value and the frequency reduction rate; the frequency reduction interval can also be divided into a plurality of sub frequency reduction intervals according to the size of the total current value, each sub frequency reduction interval corresponds to one frequency reduction rate, the larger the current value in the sub frequency reduction interval is, the larger the corresponding frequency reduction rate is, the sub frequency reduction interval where the current total current is located is determined, and the frequency reduction rate corresponding to the sub frequency reduction interval is obtained as the frequency reduction rate of the electric equipment.
The frequency reduction rate can refer to the reduction of the operation frequency of the electric equipment per unit time, and can also refer to the reduction of the operation frequency of the electric equipment per unit total current.
The controllable electric equipment is adjusted downwards according to the determined frequency reduction rate on the basis of the current operating frequency, the current operating frequency is controlled to be adjusted downwards at intervals of unit time by a certain preset frequency, the whole downward adjustment process can be stopped after being maintained for a certain time, and the whole downward adjustment process can also be stopped after the total current is reduced to a frequency holding interval. In addition, the target frequency of the electrical device may also be determined according to the frequency reduction rate, for example, the target frequency of the electrical device may be calculated according to a fitting formula obtained through analyzing a large amount of data, such as the frequency reduction rate, the target frequency of the last determined frequency reduction, or the like, or according to the frequency reduction rate, the current operating frequency of the electrical device, or the like. And after the target frequency of the frequency reduction is determined, controlling the operating frequency of the electric equipment to be reduced to the determined target frequency of the frequency reduction. The frequency reduction target frequency is less than the current running frequency of the electric equipment; in addition, the frequency reduction amount of the electric equipment can be determined according to the frequency reduction rate, and the electric equipment is controlled to operate after the determined frequency reduction amount is reduced on the basis of the current operating frequency.
Further, the step of determining the frequency reduction rate of the air conditioner according to the total current comprises:
determining the amplitude of the frequency reduction rate according to the total current;
determining the frequency reduction rate according to the amplitude and a preset frequency reduction rate; wherein the magnitude increases exponentially as the total current increases.
The preset down-conversion rate may be a minimum value of the down-conversion rates in the preset down-conversion interval, and the minimum value of the down-conversion rates may be a down-conversion rate corresponding to a minimum threshold of the down-conversion interval. Different total current values or current intervals may correspond to different magnitudes of the downconversion rate. And increasing the increment on the basis of the preset frequency reduction rate to obtain the frequency reduction rate corresponding to the current total current of the air conditioner.
Specifically, the down-conversion rate of the air conditioner can be controlled by C ═ C0+ (a)I/T1) calculating, wherein C0 is a preset frequency reduction rate or a frequency reduction rate corresponding to a minimum critical value of a frequency reduction interval, the C0 can be 2HZ/s or 3HZ/s, and the like, and C is a frequency reduction rate corresponding to the current total current of the electric equipment, (a)I/T-1) is the amplitude of the rate of downconversion, a, T are adjustment coefficients determined by extensive data analysis, a is an adjustment coefficient greater than 1, e.g. 2 or 3, etc., said T is a constant, e.g. 1.1 or 1.2, etc., a, T adjustment coefficients are advanced; and I is the current total current of the electricity environment where the electricity equipment is located. In the above exponential relationship, as the total current increases, the magnitude of the down-conversion rate of the powered device increases.
This embodiment is in when predetermineeing the interval through the total current, calculate the break-make time of circuit on-off device by the total current, judge whether need adjust the consumer through the break-make time, control the consumer operation, and then make the total current of current on-off device can not trigger the rated current value and break off, effectively avoided the unable normal operating of all present consumers, make the consumer control in the power consumption return circuit unreasonable, lead to unable reasonable power consumption, the efficiency of power consumption is poor.
