As an alternative, the chip of the intelligent breaker 120 and the motor driving circuit 212 may be powered by an external power module, for example, a bus such as Type-C may be used for connection, and the reduced direct current, such as 12V, is input to the intelligent breaker 120 at this time, so the voltage driving circuit may be directly connected to the external power module to obtain the required working voltage, and a simple reducing circuit may be provided for reducing the working voltage of the chip in the intelligent breaker 120, such as a linear voltage stabilizer. It will be appreciated that the manner of power supply for the intelligent circuit breaker 120 is not limited herein.
In one embodiment, a movable gear set 214 is disposed in the first housing 210, the movable gear set 214 includes a plurality of gears, each gear is connected by a corresponding link or direct engagement, for example, as shown in fig. 3, the movable gear set 214 includes an initial gear 1, a second gear 2, a third gear 3 and a fourth gear 4, wherein the initial gear is directly driven by a motor 213, the second gear 2 is connected with the third gear 3, a protruding structure is disposed on the third gear 3 for pushing the trip link 6 to complete the trip action, the fourth gear 4 is connected with a link 5, and the link 5 is connected with a movable contact assembly 221 in the second housing 220.

In addition, the arc extinguishing assembly is mainly used for attracting, lengthening and extinguishing an arc during breaking, improving safety and the like.
According to the lighting control system, the gateway and the intelligent circuit breaker are adopted to realize lighting control on lighting loads, corresponding longitude and latitude controllers or light sensation controllers and the like are not required to be externally connected in each lighting load, and simultaneous control on a plurality of lighting loads can be realized only by one gateway, so that the cost is lower, and meanwhile, the requirement on an installation space is lower. The on-off control is carried out through the intelligent circuit breaker, so that the breaking control of lighting load is more reliable and convenient, and the like.
Example 2
Referring to fig. 4, the present embodiment proposes a lighting control method to be applied to the lighting control system 100 of the above embodiment 1, so as to realize precise control of the lighting load 130.
For example, when calculating the switching time of the corresponding lighting load, the gateway 110 needs to obtain the position information such as the longitude and latitude of the actual installation location of each lighting load, and then execute the following steps:
step S110, the on time and the off time of the current longitude and latitude of the corresponding lighting load are calculated according to the longitude and latitude information and the date of the current longitude and latitude.
For each lighting load, the respective on-time and off-time may be calculated from its longitude and latitude information, the date of the day, and the like, as an example. In one embodiment, as shown in fig. 5, the step S110 may include the following sub-steps:
sub-step S210, calculating the noon time of the current longitude from the longitude of the current lighting load and the current date.
Illustratively, in calculating the noon time, it may be first determined from the longitude whether it is in the east or west longitude, e.g., east longitude may be represented by j=0 and west longitude by j=1; further, the noon time of the current longitude is determined according to the following formula:
Tzw＝36-(360*j+(-1)j*JD-120)/15；
wherein Tzw represents the noon time of the current longitude JD; j represents whether the current longitude JD is located in the east or west longitude.
In the substep S220, the number of days from the first day to the current day of the current year is calculated, the process angle corresponding to the current day is calculated according to the number of days, and the time of day of the current latitude is calculated according to the process angle.
Illustratively, according to the date of the day, the total day DD from 1 month 1 day to the day of the present year can be calculated, for example, without considering leap years, the following formula can be adopted for calculation:
DD＝A[N-1]+D；
wherein D represents the date, N represents the month, 12 months a year, so it can be represented as A0-A11. In this embodiment, a [ N-1] = {0, 31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334}.
It is considered that the angle of direct sunlight is also different due to different time points, which affects the sunlight time. The above-mentioned process angle mainly refers to the direct solar radiation angle of the current day, and by calculating the process angle from the current day to the corresponding solar terms, the embodiment can obtain more accurate long-time solar terms.
In this embodiment, the number of days and the time point occupied by each throttle can be determined in advance for the number of days of one year according to the four throttles of spring, summer, autumn and winter. For example, for 365 days a year, spring festival can be divided into intervals [1, 87); the summer-time throttling may be divided into intervals [87, 181); autumn-split gas can be divided into intervals [181, 271); winter to solar terms may be divided into intervals 271, 365.
Further, based on the above section division, a corresponding process angle calculation rule is set for each throttle. In one embodiment, the progress angle calculation rules for each damper relate to the number of days for the corresponding damper. Specifically, the process angle calculation rules of the spring festival, the summer festival, the autumn festival and the winter festival can be set as follows:
JC＝(((DD+8)％365)-87)*23.45/88；
JC＝(((DD+8)％365)-87)*23.45/94；
JC＝((271-(DD+8)％365))*23.45/90；
JC＝((271-(DD+8)％365))*23.45/93；
where JC represents the angle of progress of the day in the solar terms to which it belongs, and DD represents the number of days from the first day (1 month, 1 day) to the current day of the year.
Then, after the corresponding process angle is calculated, the time of day of the current latitude on the same day can be calculated according to the following formula:
Trc＝24*k+(-1) k *(360-2*arcos(sin(WD*π/180)*(tan(JC*π/180)/(cos(WD*π/180))))/360*24)；
where Trc denotes a long-time-of-day, JC denotes a progress angle, WD denotes a current latitude, k denotes whether the current latitude is located in a south latitude or a north latitude, k=1 is a south latitude, and k=0 is a north latitude.
In a substep S230, the buffering time of the current latitude is calculated.
The calculation formula of the buffer time Tb of the current latitude WD is as follows:
Tb＝0.0004*WD^3-0.0187*WD^2+0.33*WD+21。
it will be appreciated that the time before the moment when the sun rises is short, and the time when the sun falls down is long, the buffer time is taken into consideration, so that the lighting load can be correspondingly turned off and turned on in advance before the sun rises and after the sun falls down, so that the purpose of saving electricity can be achieved.
And step S240, calculating the opening time and the closing time of the current longitude and latitude on the same day according to the noon time, the long-time day and the buffering time.
Illustratively, when the noon time Tzw corresponding to the longitude, the day time Trc corresponding to the latitude and the buffer time Tb are calculated, the opening time and closing time of the current day under the longitude and latitude may be calculated according to the following formulas:
Topen＝(Tzw+Trc/2+Tb)％24；
Tclose＝(24+Tzw-Trc/2-Tb)％24。
it should be noted that the system time of the gateway 110 is taken as the eastern eight area instead of the current latitude and longitude time as the standard in this embodiment, so that the lighting system can be suitable for different areas and the like.
And step S120, a closing instruction is sent to the intelligent circuit breaker 120 according to the opening time, so that the intelligent circuit breaker 120 controls the corresponding lighting load to be opened after receiving the closing instruction.
And step S130, sending a switching-off instruction to the intelligent circuit breaker 120 according to the closing time, so that the intelligent circuit breaker 120 controls the corresponding lighting load to be closed after receiving the switching-off instruction.
Wherein latitude and longitude information for each lighting load may be pre-associated with a unique identification of the corresponding intelligent breaker 120. Illustratively, after calculating the opening time and the closing time, when the opening time is reached, the gateway 110 will send a closing command to the intelligent breaker 120 corresponding to the longitude and latitude, and the intelligent breaker 120 controls the corresponding lighting load to be opened. Similarly, when the closing time is reached, the gateway 110 will send a switching-off instruction to the intelligent breaker 120 corresponding to the longitude and latitude, and then the intelligent breaker 120 controls the corresponding lighting load to be closed, so as to complete the opening and closing control of the lighting load in the same day.
Further, the gateway 110 may immediately start the opening and closing time for the next time after each power-up initialization, and after each day of the switching-off and switching-on actions, and so on.
According to the lighting control method, the gateway timely calculates the opening and closing time of each lighting load every day according to the longitude and latitude of the actual installation place of each lighting load and the date of the day, and compared with the existing fixed time control scheme, table lookup control scheme and other schemes, the lighting control method is more accurate in control; in addition, as the corresponding longitude and latitude controllers or light sensation controllers and the like are not required to be externally connected to each lighting load, the simultaneous control of a plurality of lighting loads can be realized by only one gateway, the cost is lower, and the requirement on the installation space is lower. In addition, each lighting load is controlled to be on-off through the intelligent circuit breaker, and the intelligent circuit breaker can realize wireless communication with the gateway and the like, so that the breaking control of the lighting load is more reliable and convenient.
