The application can also include operating a switch or closing a floodgate manually, substantially be still on-off circuit, when by lower switch, output One high level, control unit cut off supply line after receiving the high level signal, when switching reset, export a low level, control Unit processed connects supply line after receiving the low level signal.
In this example, the specific calculating process of the first detected value or the second detected value is:According to the first signal, then work as control When unit receives the first signal continuously occurred, then the continuous appearance the maintained time is designated as t2, and presses formula A= T2/t, t=(t3-t1), calculated to obtain the first detected value A;Or according to secondary signal, then when control unit connects When receiving the secondary signal continuously occurred, then the continuous appearance the maintained time is designated as t4, and presses formula B=t4/t, t= (t3-t1), calculated to obtain the second detected value B;Or B is calculated by B=1-A;Or calculated by A=1-B To A;Wherein, t represents the described cycle, and for each cycle t, control unit is with first the first signal received or second Start time t1 at the time of residing for signal as cycle t, accordingly, if being used as week at the time of using residing for first the first signal Phase t start time t1, then after the first signal interruption, end at the time of the first signal is residing when occurring again as cycle t Point moment t3, if as cycle t start time t1 at the time of using residing for first secondary signal, when secondary signal is interrupted Afterwards, end of time t3 at the time of residing when secondary signal occurs again as cycle t;
In this example, when the first detected value is less than or equal to set the first reference value as dutycycle reference point, Control unit judges load for standby, or, when the second detected value more than or equal to set as dutycycle reference point During the second reference value, control unit judges that load to be standby, refers to:For continuous several cycles t, when each cycle t is counted Obtained A is respectively less than or during equal to A1, then judges that load in standby, otherwise redefines continuous several cycles t Start cycle, whether t, and rejudged in standby;Or for continuous several cycles t, when each cycle t is counted Obtained B is all higher than or during equal to B1, then judges that load in standby, otherwise redefines continuous several cycles t Start cycle, whether t, and rejudged in standby.
The accumulation interval that we can define several cycles t is 15 minutes, then during 15 minutes, as each cycle t The A being calculated is respectively less than or during equal to A1, then control unit judges that load is in holding state, while controlling switch unit is cut Cut-off electric line, therefore, under normal condition, standby automatic circuit break function at least needs can just embody for 15 minutes, is economized on electricity when using Substantially it is to shorten accumulation interval, such as 30 seconds, then the A that each cycle t in 30 seconds is calculated is respectively less than after test cell Or during equal to A1, then control unit judges that load is in holding state, while controlling switch unit cut-out supply line, that is, starts Control unit calculates a series of dutycycles in the following short period to judge whether load is in standby, is waited so as to shorten Time, so, the stand-by period is significantly reduced, this setting very hommization, be easily installed commissioning staff, also allow for displaying production Product function, improve efficiency.
T's start cycle is redefined as, once there is the cycle t that A is less than or equal to A1, or, it is more than once there is B Or the cycle t equal to B1, then cycle t is as t start cycle, so, is more conducively judged whether in time in standby, raising Judging efficiency.
The A obtained in the case of loaded work piece is designated as A2, and A1+B obtains C, and C is less than A2, the C as the first reference value, or, The B obtained in the case of loaded work piece is designated as B2, and B1-D obtains E, and E is less than B2, and the E is as the second reference value, and so, A1+B increases Big A1, B1-D reduce B1, and the setting purpose is the adaptability for strengthening the application, so as to tackle the fluctuation of power utilization environment Influence, specifically using great B or D, can be determined according to the degree of fluctuation of actual power utilization environment, naturally it is also possible to subjectivity setting One value, for example B or D are 0.02.
Initial A1 or B1 is set by predetermined manner, to redefine A1 or B1 is then started by trigger element, so, is write from memory In the case of recognizing, judged by default A1 or B1 as reference value, and redefine A1 or B1, then can be determined in setting person Load is in the switch S4 of operation switching circuit under ideal case, and A1 or B1 is redefined to realize by switching S4 startups, on State to set and can avoid A1 or B1 confusion, it is ensured that adaptability of the utility model in each use environment, to user with Carry out more preferable usage experience.
Started by switching S4 to realize that redefining A1 or B1 refers to, for example, A1, after Operation switch S4, control unit The A being calculated using within following a period of time is as corresponding A1, for example next a period of time can include for 20 week Phase t, the value that 20 A that 20 cycle t are calculated averagely once are determined is as A1;Such as B1, as Operation switch S4 Afterwards, the B that control unit is calculated using within following a period of time is as corresponding B1, for example next a period of time can wrap Ten cycle t are included, the value that ten B that ten cycle t are calculated averagely once are determined is as B1.
A and B can be described as the two sides of power supply, i.e., in a cycle t, except A is exactly B, then preferable in power supply quality In the environment of, that is, fluctuate it is small, if A, it is known that if B=1-A, similarly, if B, it is known that if A=1-B;Supply line is to refer to, rather than It is confined to the electric wire of access load, all positions for being adapted to current sampling on feeder circuit.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
