A kind of switching on and shutting down principle of Multifunction open shutdown circuit of the present invention is as follows:
1) under off-mode when button (S1) is pressed, outside power supply (DC_IN) will to whole on/off circuit and Back-end system is powered, and processor can work together at once.
2) the processor detection electric circuit inspection in software controlled circuitry is pressed to button (S1), then processor is controlled Circuit will draw high power control pin (PWR_CON) level of back-end system.Even if now trip switch, back-end system Power supply will not also disconnect.It is of course also possible to after directly the power supply that the one of voltage of back-end system is 3.3V or so is connected to The power control pin (PWR_CON) of end system, the action that alternate process device is drawn high.
Wherein, how long button (S1) is by starting shooting, and the time is exactly processor detection circuit inspection in software control module Measure button (S1) and press this period that processor control circuit draws high the power control pin level of back-end system, can It is configured with software within a processor, the personal settings for making it more meet people make people obtain more preferable use feeling By.
3) after system boot, the power supply level of back-end system directly can be dragged down realization shutdown by processor.
If 4) processor crashes, when software can not realize shutdown, long-press button (S1), the hard shutdown in hardware control module Circuit is started working, and the electric capacity (C3) in hard shutdown circuit is started to charge up, and when being charged to certain voltage, is connected with electric capacity (C3) Metal-oxide-semiconductor (Q1) is turned on, and the power control pin level of back-end system is directly dragged down into realization shutdown.Wherein, in hard shutdown circuit Resistance (R9) can effectively extend electric capacity (C3) charging interval, prevent that the hard unused time is too short.
5) after shutting down, the electric capacity (C3) in hard shutdown circuit is quick by electricity by the discharge circuit in hardware control module Bleed off, it is to avoid when and then start, just the charged power control pin by back-end system is electric in electric capacity (C3) short time It is flat to drag down all the time, lead to not start.
The time of long-press button (S1) shutdown is exactly the time that electric capacity (C3) charging reaches metal-oxide-semiconductor (Q1) conducting, with electric capacity (C3) capacity is relevant, can adjust the time shut down firmly by changing the electric capacity of different capabilities.Because button (S1) is pressed Hardware control circuit and software controlled circuitry are to work simultaneously, so the time of (S1) is pushed button when start to be surpassed The time of shutdown really up to the mark, inside processor the time of long-press button (S1) start of software design patterns can not exceed shut down firmly when Between.
During button (S1) is pinned, finger may cause button (S1) occurs in some moment disconnected because of shake Open, cause the level of the power control pin (PWR_CON) of back-end system to be dragged down by moment, cause boot failure.And in resistance (R7) after two ends shunt capacitance (C1), disconnected in a flash even in certain that button (S1) is pinned, within the time, electric capacity (C1) it can be discharged, the power control pin (PWR_CON) for maintaining back-end system is high level, keeps back-end system power supply control The level of pin (PWR_CON) processed is steady, improves the Experience Degree of user.
The control pin (CPU_CON) of processor in processor control circuit 42, may after certain is interfered in a flash The level of the power control pin (PWR_CON) of back-end system can be dragged down, cause boot failure.And at resistance (R8) two ends After shunt capacitance (C2), even if the control pin (CPU_CON) of processor is interfered in a flash at certain, within the time, electric capacity (C2) it can be discharged, the power control pin (PWR_CON) for maintaining back-end system is high level, keeps back-end system power supply control The level of pin (PWR_CON) processed is steady, improves the Experience Degree of user.
As shown in figure 3, carrying out the method for start-up and shutdown of switching on and shutting down using Multifunction open shutdown circuit, starting-up method is:
Button (S1) is pressed;
If the time of button is less than the hard unused time, start shooting successfully;
If the time of button is more than or equal to hard unused time, boot failure;
Software closedown method is:It is controlled using processor, realizes shutdown;
Hardware closedown method is to press button (S1);
If the time of button is more than or equal to the hard unused time, shut down successfully;
If the time of button is less than hard unused time, shutdown failure.
Using above-mentioned preferred scheme, method for start-up and shutdown is easy and effective.
It is assumed that in hardware shutdown circuit, the grid voltage of metal-oxide-semiconductor (Q1) is V, external input power (DC_ IN voltage) is Vi, the resistance of resistance (R9) is R, and the capacitance of electric capacity (C3) is C, and the time of hardware shutdown, (i.e. button (S1) was pressed Time firmly) be t, then the functional relation between individual parameter is as follows:
V=Vi×(1-e-t/RC)
Wherein:E is natural constant, when V value reaches metal-oxide-semiconductor Q1 conducting voltage, is achieved that hard shutdown.It is determined that The conducting voltage of metal-oxide-semiconductor (Q1) by above-mentioned formula with that after the accurate hard unused time, can obtain RC value.So as to choose The capacitance electric capacity (C3) of the resistance (R9) of suitable resistance.
A kind of Multifunction open shutdown circuit of the present invention, its is simple in construction, and each several part division of labor is clear and definite, by chip piece and multiple Discrete component is constituted, and cost is low, realizes basic on/off circuit function, realizes software start and hardware shutdown, and software Start and hardware unused time are adjustable, and the setting of software available machine time can effectively prevent button imprudence error from pressing, and make Into machine is opened by mistake, it is more than the available machine time less than the hard unused time when the time that button is pressed down, successfully starts shooting;And when processor crashes When, software shutdown can not be realized, by the way of hardware shuts down so that operation is simpler.
Because a kind of electromechanical road of multifunction switch of the invention substantially uses discrete component, component utilization rate is high, And when the voltage of external input power is changed, some divider resistances can be adjusted to be adapted to, it is not using routine Single-chip microcomputer so that overall circuit structure is more simple and clear, and functional.
A kind of Multifunction open shutdown circuit controls the opening and closing of back-end system power supply using software controlled circuitry 4 come software, and Hardware control circuit 3 can effectively realize the closing of back-end system power supply, and back-end system electricity can not be realized in software controlled circuitry During the closing in source, hardware control circuit still can rapidly realize the closing of its rear end system power supply, realize shutdown.Partial pressure electricity Road the high voltage of external input power is got into the power supply control that a suitable voltage detects circuit and back-end system to processor Pin processed, when the voltage of external input power changes, can adjust the resistance of divider resistance to adapt to processor detection The power control pin of circuit and back-end system so that the circuit can compatible any voltage dc source input, it is compatible Performance is more preferable.
The circuit is simple, cost is low and safe and reliable, functional, and power consumption is few.
New preferred embodiment, it is noted that for the person of ordinary skill of the art, is not departing from this hair On the premise of bright creation design, various modifications and improvements can be made, these belong to protection scope of the present invention.
