Embodiment
Hereinafter with reference to correlative type, a kind of cycling switch control circuit and control method thereof according to preferred embodiment of the present invention are described, wherein identical assembly and signal will be illustrated with identical reference marks.
Please refer to shown in Figure 2ly, it is the schematic diagram of a kind of cycling switch control circuit 1 of preferred embodiment of the present invention.
Cycling switch control circuit 1 comprises a switch loop 11, one first control loop 12 and one second control loop 13.Cycling switch control circuit 1 of the present invention can be used for controlling a control panel E, makes it have different operating modes and function.In addition, control panel E of the present invention can be such as being scavenger fan or cold and warm air heating radiator or light fixture etc.The present embodiment is take scavenger fan E as example, and so it is non-limiting.
In the present embodiment, control panel E can be for example the equipment of a use DC driven.During the equipment that if control panel E is a use interchange to be driven, it is inner with built-in circuit of circulation interchange (DC/AC) always (scheming to show), makes the DC driven signal DS of input control panel E be converted to AC signal, to drive control panel E.
The first control loop 12 is electrically connected with switch loop 11 and control panel E respectively, and produces one first control signal CS1 according to the change that drives signal DS.Wherein, the first control loop 12 can for example have one first filter unit 121, a trigger element 122 and a delay cell 123.Wherein, the first filter unit 121 is electrically connected with switch loop 11 and control panel E, and trigger element 122 and the first filter unit 121 are electrically connected, and delay cell 123 is electrically connected with trigger element 122 and the second control loop 13.
The first filter unit 121 is exported a pulse signal P according to the change that drives signal DS.In the present embodiment, the first filter unit 121 can be for example high pass filter (High-Pass Filter).High pass filter only allows the signal of high frequency to pass through, and with the signal filtering of low frequency.Therefore, when switch loop 11 continues conducting, do not change because driving signal DS, cause and drive the signal that signal DS there is no high frequency, therefore the first filter unit 121 can not exported pulse signal P, just can not produce first yet and control signal CS1, and then can not change operating mode and the function of control panel E.
Table 1 is the truth table (Truth Table) of trigger element 122.Wherein, D is the input of flip-flop, and G is the activation input of flip-flop, and Q is the output of flip-flop, and N is another output of flip-flop, and the level of N is opposite with Q.In other words, when Q was high level, N was low level; Otherwise when Q was low level, N was high level.
| G | D | Q | N |
| 0 | X | Q | N |
| 1 | X | Q | N |
| ↑ | 0 | 0 | 1 |
| ↑ | 1 | 1 | 0 |
Table 1
As shown in Table 1: only when the activation input G of flip-flop becomes high level 1 by low level 0, the level of the output Q of flip-flop just can equal the level of input D, at this moment, the level of the output Q of flip-flop can maintain until when the activation input G of flip-flop becomes high level 1 again by low level 0 next time.Simultaneously, because the level of the output Q of flip-flop is identical with the level of the input D of flip-flop, so the level of output N is opposite with input D.
Therefore, when the activation input G of trigger element 122 is transferred to the moment of high level by low level, the signal of the output Q of trigger element 122 output and the input D of trigger element 122 (i.e. the second control loop 13 export one second control signal CS2) have same level.In other words, when pulse signal P transferred high level to by low level, the trigger signals T (the output N by trigger element 122 is exported) of trigger element 122 outputs and second controlled signal CS2 and has opposite levels.
The trigger signals T input delay unit 123 of trigger element 122 output, delay cell 123 postpones trigger signals T to export after a period of time, and the signal of output is first and controls signal CS1, and inputs to the second control loop 13.
The second control loop 13 is electrically connected with the first control loop 12 and control panel E respectively, the second control loop 13 has an energy-storage units 131, energy-storage units 131 is controlled signal CS1 according to first and is carried out charging and discharging, controls signal CS2 to input the operation mode of the first control loop 12 and control control panel E so that the second control loop 13 produces one second.In the present embodiment, energy-storage units 131 is take capacitor as example.
The second control loop 13 also can have reverse unit 132 and a discharge cell 133, and oppositely unit 132 is electrically connected with delay cell 123 and discharge cell 133 respectively, and discharge cell 133 is electrically connected with energy-storage units 131.Oppositely to control signal CS1 with first anti-phase in unit 132, with conducting and the cut-off of controlled discharge unit 133.And energy-storage units 131 discharges according to the conducting of discharge cell 133.
The second control loop 13 also can have a charhing unit 134, and it is electrically connected with delay cell 123, reverse unit 132, discharge cell 133 and energy-storage units 131 respectively.Charhing unit 134 is controlled signal CS1 to energy-storage units 131 chargings according to first.In other words, when the first control signal CS1 was high level, first controls signal CS1 flowed through charhing unit 134 so that energy-storage units 131 is charged, and this moment, discharge cell 133 was cut-off state.
Please refer to shown in Figure 3ly, it is the circuit diagram of the second control loop 13 of cycling switch control circuit 1.
When the first control signal CS1 is high level, first controls signal CS1 via the first resistor R1 and diode D1, so that energy-storage units 131 is carried out quick charge, and then make the second control signal CS2 become high level, with input trigger element 122 and control panel E (Fig. 3 does not show), therefore, can change operating mode and the function of control panel E.
During because of discharge cell 133 cut-off, for energy-storage units 131, diode D1 is reverse bias, therefore the stored electric weight of energy-storage units 131 can't run off fast, therefore, between the operating mode of control panel E was switched, cycling switch control circuit 1 can be kept the energy supply of control panel E a period of time.Therefore, energy-storage units 131 of the present invention does not need as known techniques, needs the energy storage component (energy storage component 211 of Fig. 1 for example of larger capacity; In addition, electric power loop 22 and drive the existence that loop 23 also has noise electric capacity).
In the present embodiment, discharge cell 133 and the first switch S 1 can be for example field-effect transistor (Field-Effect Transistor, FET).Field-effect transistor can be divided into maqting type field-effect transistor (JFET) or mos field effect transistor (MOSFET), in this, take n type field effect transistor (NMOS) as example.
When the first control signal CS1 is high level and the first switch S 1 conducting, the electric current I that voltage V produces the 3rd resistor R3 that flows through, the second end S12 of first switch S 1 of flowing through again and the 3rd end S13 of the first switch S 1, electric current I does not flow into the first end 1331 of discharge cell 133, therefore, discharge cell 133 cut-offs are not therefore energy-storage units 131 discharges, second controls signal CS2 does not change its level yet, and meaning namely can not change operating mode and the function of control panel E.
When the first control signal CS1 is low level and the first switch S 1 cut-off, the electric current I that voltage V produces the 3rd resistor R3 that flows through, flow into again the first end C11 of the first capacitor C1, make the first capacitor C1 charging, last conducting discharge cell 133, and then make energy-storage units 131 through the 3rd end 1333 discharges of the second end 1332 and the discharge cell 133 of discharge cell 133, so, make simultaneously the second control signal CS2 be reduced to the low level signal.
Please refer to shown in Fig. 4 A, cycling switch control circuit 1 also can comprise a commutation circuit 14 and a mains switch 15, and commutation circuit 14 is electrically connected with switch loop 11 and mains switch 15 respectively.When mains switch 15 conductings (namely drop into), commutation circuit 14 can produce dc signal DC according to an AC signal AC, with input switch loop 11.Wherein, commutation circuit 14 has the power supply changeover device (Converter) 141 that an interchange turns direct current (AC/DC), makes the AC signal AC of input be converted to dc signal DC, and input switch loop 11.Interchange turns the power supply changeover device 141 of direct current for known techniques commonly used, repeats no more in this.
Cycling switch control circuit 1 also can comprise one the 3rd control loop 16, it is electrically connected with switch loop 11 and commutation circuit 14 respectively, and control signal CS3 with actuating switch loop 11 according to AC signal AC output one the 3rd, so that producing according to dc signal DC, switch loop 11 drives signal DS, to drive control panel E.
In other words, when mains switch 15 dropped into, AC signal AC input commutation circuit 14 and the 3rd control loop 16, the power supply changeover device 141 that AC signal AC turns direct current through the interchange of commutation circuit 14 were converted to dc signal DC and input switch loop 11; In addition, signal CS3 are controlled in the 3rd control loop 16 output the 3rd, with input switch loop 11, make switch loop 11 conductings, and switch loop 11 outputs drive signal DS, make control panel E running.When mains switch 15 continued conducting, the 3rd control loop 16 continued output the 3rd and controls signal CS3, with actuating switch loop 11, so control panel E continuous running and do not change its operating mode and function.
The 3rd control loop 16 can for example have a voltage transformation unit 161 and one second filter unit 162.Voltage transformation unit 161 is electrically connected with commutation circuit 14 and the second filter unit 162 respectively, the second filter unit 162 and switch loop 11 electric connections.Voltage transformation unit 161, makes the second filter unit 162 produce the 3rd and controls signal CS3 to input the second filter unit 162 according to AC signal AC output one transformation signal TS, with conducting and the cut-off in control switch loop 11.
In the present embodiment, after voltage transformation unit 161 decays AC signal AC, output transformation signal TS is to input the second filter unit 162.The second filter unit 162 can be for example low pass filter (Low-PassFilter), and it only allows the signal of low frequency (for example 60HZ) pass through the part filtering of the high-frequency noise of AC signal AC.Therefore, when mains switch 15 inputs and lasting conducting, the second filter unit 162 of the 3rd control loop 16 allows the AC signal AC of low frequency control signal CS3 by continuing output the 3rd, make switch loop 11 lasting outputs drive signal DS, make control panel E running and do not change its operating mode and function.
In addition, please refer to shown in Fig. 4 B, switch loop 11 can be a field-effect transistor, and its gate terminal and the 3rd control loop 16 are electrically connected, its source terminal and drain electrode end respectively with commutation circuit 14 and the first control loop 12 electric connections.Grid and the actuating switch loop 11 of signal CS3 input field effect transistor controlled in the 3rd of the 3rd control loop 16 output, makes switch loop 11 outputs drive signal DS, to input and to control control panel E and the first control loop 12.
Please be simultaneously with reference to Fig. 4 A and Fig. 5 so that the detailed start situation of cycling switch control circuit 1 of the present invention to be described.Wherein, Fig. 5 is the sequential chart of cycling switch control circuit 1, and abscissa is time shaft.
When mains switch 15 drops into and conducting in a very first time T1, commutation circuit 14 output dc signal DC and input switch loop 11, simultaneously, the 3rd control loop 16 produces the 3rd and controls signal CS3, make switch loop 11 outputs drive signal DS, therefore during very first time T1, dc signal DC, the 3rd controls signal CS3 and drives signal DS and is high level.In the moment of mains switch 15 because of the input conducting, the first filter unit 121 produces a pulse (in Fig. 5, when the T1 time point, the up surging of pulse signal P appearance) and inputs trigger element 122 according to driving signal DS moment.At this moment, the second control signal CS2 is a low level, therefore the trigger signals T of trigger element 122 outputs is high level (opposite with the level of the second control signal CS2), after delayed unit 123 postpones a time t, first controls signal CS1 also becomes high level, and therefore, energy-storage units 131 carries out quick charge via charhing unit 134, make the second control signal CS2 also become high level, E changes its operating mode and function with the input control panel.
First of high level is controlled signal CS1 after reverse unit 132 is reverse, and conducting the first switch S 1 is not charged the first capacitor C1, therefore discharge cell 133 cut-offs, energy-storage units 131 can't discharge, and the stored electric weight of energy-storage units 131 can be kept.
When mains switch 15 continues conducting after very first time T1, switch loop 11 also continues conducting, driving back number DS and the 3rd controls signal CS3 and is continuously high level, because of the driving number of returning DS and the no change after conducting, therefore pulse signal P is still low level, make the trigger signals T, first of trigger element 122 output control signal CS1 and control second the controlling signal CS2 and all do not change its level of operating mode of control panel E, control panel E does not change its operating mode and function yet.
When mains switch 15 changes open circuit into when (namely ending) in one second time T 2 by input, switch loop 11 is controlled signal CS3 because of the 3rd of the 3rd control loop 16 and is ended, make control panel E lose driving signal DS and decommission, at this moment, the stored energy of energy-storage units 131 is preserved because of the diode D1 of charhing unit 134, therefore second the controlling signal CS2 and kept a period of time of high level.
When one the 3rd time T 3 dropped into again, signal CS3 conducting was again controlled because of the 3rd of the 3rd control loop 16 in switch loop 11 when mains switch 15, made to drive signal DS and again drive control panel E and input to the first control loop 12.The moment of again dropping into due to mains switch 15, drive signal DS after the first filter unit 121, pulse signal P moment of output produces a pulse (in Fig. 5, when the T3 time point, the up surging that pulse signal P occurs) input trigger element 122, therefore controlling signal CS2, the trigger signals T of trigger element 122 outputs and second has opposite level, because the second control signal CS2 is the high level signal, therefore trigger signals T becomes low level, after delayed unit 123 postponed, first of the first control loop 12 outputs were controlled signal CS1 and are also become low level.
The signal that the low level first rear preparation in reverse unit 132 of controlling signal CS1 input the second control loop 13 inputs to the grid of discharge cell 133 is high level, and then conducting discharge cell 133, energy-storage units 131 is discharged and make the second control signal CS2 become low level by previous high level.
When mains switch 15 in one the 4th time T 4 by dropping into when again changing open circuit into, switch loop 11 is controlled signal CS3 because of the 3rd of the 3rd control loop 16 and is ended, make control panel E lose driving signal DS and decommission, at this moment, first control that signal CS1 and second controls that signal CS2 all keeps low level and the operating mode and the function that do not change control panel E.
The turn-on action that repeats above-mentioned mains switch 15 can make again energy-storage units 131 chargings, and then makes the second control signal CS2 become high level, with operating mode and the function that again changes control panel E.
From the above, cycling switch control circuit 1 of the present invention is with the operating mode of the action control control panel E of the conducting of mains switch 15 and cut-off and the switching of function, therefore, can make the distribution between cycling switch control circuit 1 and control panel E comparatively simple and easy, can be comparatively simple when changing as wish the equipment that only has simple Push And Release function.In addition, when mains switch 15 changes cut-off into by conducting within the short time, electric energy can be stored in energy-storage units 131, and control panel E in start with the action of closing between, the stored energy of energy-storage units 131 can be kept lasting start a period of time of control panel.Therefore, control circuit does not need the jumbo energy storage component (energy storage component 211 of Fig. 1 for example; In addition, electric power loop 22 and drive the existence that loop 23 also has noise electric capacity), also can reach energy-conservation effect.
Please refer to shown in Figure 6ly, it is the schematic diagram of a kind of cycling switch control circuit 1a of another aspect of preferred embodiment of the present invention.
Cycling switch control circuit 1 main difference of the cycling switch control circuit 1a of this aspect and a upper aspect is, the first control loop 12a of the cycling switch control circuit 1a of this aspect is a microprocessor.Wherein, the first control loop 12a has the first filter unit 121, trigger element 122 and the identical function of delay cell 123 of the first control loop 12 of cycling switch control circuit 1, make the first control loop 12a to control signal CS2 output the first control signal CS1 according to driving signal DS and second, the action that makes the energy-storage units 131 of the second control loop 13 charge and discharge, control the voltage level of signal CS2 to change second, and then can change operator scheme and the function of control panel E.
