Fig. 2 is auto-power-off energy-saving switch internal control gear block diagram.
Fig. 3 is on/off leak control and check circuit diagram.
Embodiment
1 to 3 embodiment of the present utility model is described further by reference to the accompanying drawings:
A kind of auto-power-off energy-saving switch, comprises switch housing and internal control mechanism.Switch housing is provided with the double-point double-throw switch 3, the LED display 2 that control feed circuit break-makes and between the dynamic circuit breaker stopping time, arranges button 1 for arranging double-point double-throw switch, as shown in Figure 1.Wherein, LED display coordinates with internal control mechanism and also can be used as clock.
As shown in Figure 2, internal control mechanism is primarily of module compositions such as supply module, controller, on/off control and testing circuit, button setting, LED displays.
On/off leak control and check circuit connects the moving together contact of double-point double-throw switch, its folding condition of real-time detection and folding time, and testing result is transferred to controller, controller by the comparison between the dynamic circuit breaker stopping time of testing result and setting, and controls the folding condition of its double-point double-throw switch according to comparison result.
On/off leak control and check circuit comprises on/off detection branch and on/off controlling brancher.On/off controlling brancher comprises relay and triode Q1; The response contact of relay is connected in feed circuit, the collector of triode connects high level by the coil of relay, reverse hold-off diode D1 is also connected with, the grounded emitter of triode Q1, base stage connection control device between the collector of triode and high level.One way switch of double-point double-throw switch is connected in feed circuit, and another way switch is connected in on/off detection branch, on/off detection branch connection control device.
The main control chip of controller is single-chip microcomputer, and the different pins of single-chip microcomputer connect respectively and arrange button, LED display, the base stage of triode and on/off detection branch.
Single-chip microcomputer is circumscribed with watchdog circuit chip.Watchdog circuit chip realizes electrification reset, power-off preservation and controller function monitoring.
As shown in Figure 3, the base stage of the pin P2.0 connecting triode of single-chip microcomputer, the collector of triode connects high level (9V power supply) by the coil of relay; P2.5 connects on/off detection branch, and when double-point double-throw switch closes, voltage is 5V, P2.5 is the high electricity frequency of logic; When the switches are opened, voltage is 0V, P2.5 is logic low electricity frequency.
When P2.0 is high electricity frequency, triode Q1 conducting, relay coil obtains electric, and its respective switch closes, and presses double-point double-throw switch, and upper contact closes, 220V power voltage supply, circuit ON, and electric light lights; Lower contact closes, and realizes the monitoring of switch motion number of times.
By counting the state of P2.5, to determine the number of times of double-point double-throw switch action.During normal power supply, the relay response closing of contact, dormitory illuminator is controlled by double-point double-throw switch completely.
When after system blackout, close if P2.5 is high electricity frequency and double-point double-throw switch, the pin P2.0 output low level of single-chip microcomputer, triode disconnects, relay coil dead electricity, then the disconnection of relay response contact, and feed circuit are in off-state.
Restore electricity, if need again be energized, press double-point double-throw switch and once reset, the pin P2.0 of single-chip microcomputer exports high electricity frequently simultaneously, and the now relay response closing of contact, illuminator is controlled by double-point double-throw switch, thus realizes auto-power-off energy-saving.
The part do not addressed in the utility model adopts or uses for reference prior art and can realize.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this instructions; made all equivalently to substitute, obvious form of distortion, within the essential scope all dropping on this instructions, protection of the present utility model ought to be subject to.
