Abstract
The invention provides an energy-saving smart switch, and a load circuit and a control circuit of the switch are totally isolated. The switch comprises a battery, a microprocessor, a sensor and a relay. The relay is a magnetic latching relay or an electric latching relay. The sensor can be one or a combination of a few selected from an audio sensor, a touch sensor, an accelerometer, a gyroscope, a vibration switch and a mechanical switch. When a load does not work, the microprocessor is in a hibernation state. After the sensor is operated, an interrupt signal of the sensor wakes up the microprocessor; and after the microprocessor analyzes a sensing signal, the relay is closed, and the microprocessor changes to a timing state. If the sensor is operated again, the relay is disconnected. If no operation is done when the timing is completed, the microprocessor automatically disconnects the relay, and the whole smart switch changes to a hibernation energy-saving state. When the sensor selects vibration switches, a plurality of vibration switches can achieve multi-point control through simple parallel or series connection.
Description
Technical field
The present invention relates to the panel-switch of the make-and-break control switch of circuit, particularly lighting of home and the control switch of socket for domestic electric appliances.
Background technology
Using mechanical contact-type switch in traditional home lighting, its great advantage is simple and not power consumption.But, if forgetting after opening to close, light fixture remains powered on state, will result in the biggest waste.Therefore some intelligent switch adds the microprocessor (or control circuit) controlled now, it is possible to achieve automatically cut off power supply on time.Due to the existence of microprocessor, triggering (or sensing) parts of switch become to enrich very much, in addition to mechanical button or tumbler switch, and the also mode such as acoustic control, touch.But there are some problems in these switches, first: in switch, load high pressure forceful electric power (such as the 220Vac civil power of China) and control light current cannot be completely isolated, there are some interference, so occurring that night lamp dodges situation (particularly this to led highstrung device), interference sleep；Furthermore: the sensing part of control circuit and relay need long-time power supply (or in running order), still there is waste of energy；Last: the induction module of switch has bigger limitation, it is generally used for outdoor corridor such as audio-switch and is not suitable for indoor quietly situation, the opereating specification of soft-touch control is less (the usually area at about 1 square centimeter of switch panel center), and need to touch with exposed clean finger, wear glove or hands cannot operate time dirty.
It is an object of the invention to provide a kind of load circuit and the completely isolated energy-conserving intelligent switch of control circuit, it is a further object of the present invention to provide a kind of operation switch of energy-conserving intelligent more easily.
Summary of the invention
The power consumption of electronically controlled intelligent switch is essentially from the relay of control forceful electric power load circuit folding, and the maintenance of relay needs power consumption.In the present invention, replace conventional relay with latch-in relay (magnetic latching relay or electronic guard relay).Different with common relay switch, the movable contact of magnetic latching relay or stationary contact use alnico magnets, therefore switch after action executing (open or close) completes, two contacts keep constant because of the magnetic force of self, therefore it is not required to maintain power supply (on market, to have a class magnetic latching relay to still need to power supply in the holding stage, but reduce several order of magnitude when power consumption is compared with action, reach a microampere rank, therefore can also ignore).Electronic guard relay is to utilize micromachine to move movable contact make switch Guan Bi or disconnect, and after action completes, the elastic force having due to movable contact and stationary contact self or frictional force maintain its state, are therefore not required to continue power supply.
Owing to the maintenance of relay is no longer necessary to power consumption (or power consumption is extremely low), and present microprocessor energy consumption is the lowest, therefore controlling device can use battery to power, thus need not be from high-voltage load circuit (such as illuminating lamp live wire, socket for domestic electric appliances etc.) transformation power taking.Therefore, the low-voltage power supply of load circuit and controller achieves isolation, eliminates the interference to control circuit of the high-voltage load circuit.
For reducing energy consumption further, microprocessor uses the device with park mode, in order to realize control, it is necessary to increase an interrupt flip-flop (trigger produces level signal, exports the middle fracture of microprocessor, as wake-up signal).This interrupt flip-flop is i.e. the action interface between intelligent switch of the present invention and operator, the most also referred to as operates induction apparatus.Induction apparatus must be able to the interrupt signal provided for waking up microprocessor up, and simplest induction apparatus is that button or dial type mechanical switch, its structure and work process are just as the shift knob on each electric appliances such as mobile phone, computer.The switch of this push button can also increase some additional functions, such as button duration, the number of times etc. of button after accessing microprocessor, these changes can be differentiated for different control instruction through microprocessor analysis, it is achieved different operations.
Audio sensor in the market, touch sensor, shaking sensor is (such as MEME accelerometer, vibration switch), angular transducer (such as: gyroscope etc.) can serve as the induction apparatus of the present invention, they can not only provide the most initial wakeup interrupt signal, it is also possible to provides more signal for realizing the instruction identification of complexity.
Preferably selecting of induction apparatus of the present invention is vibration switch, and it is a type of structured, small, with low cost device.Vibration switch most widely one of application is the Glittering shoes of child, and it is that vibration switch, battery and led are placed in sole, causes switch frequently Guan Bi to control led and produce glittering effect when walking about.Vibration switch is divided into spring type and the big class of ball-type two, replaces press button with this vibration switch, is possible not only to obtain interrupt trigger signal, and because themselves being exactly shaking sensor, therefore realizes more function.Vibration switch is used to have following advantage as induction apparatus: first, the whole housing accommodating vibration switch is all that (whole switch case optional position is all touch point for the interface of intelligent switch and operator, unlike button is confined to button itself, touch screen is confined to screen itself), and surface of shell material and shape have more selection, as long as vibration signal can be transmitted very well, it is simply that good operating space, therefore the outward appearance of housing will be the most rich and varied；It addition, the intensity of vibrations, frequency the most therefrom fracture are input to microprocessor, therefore can realize the instruction identification of more complexity, i.e. realize more Intelligent control；Further, be substantially mechanical switch due to vibration switch, therefore can realize simple (open type snap switch) in parallel or series connection (closed type ball switch) realizes multiparty control (such as the same light fixture of multiple on-off control in a room).
Due to the existence of microprocessor, therefore can realize timing, clocking value can be stored in the fixed value of microprocessor, if needing variable value, only need to increase a DIP device (connecting the I/O mouth of microprocessor, directly read in numerical value) and carrying out setting and modifying；The amendments at any time such as clocking value can also utilize button to press time length or continuous key-press number of times or the oscillation intensity of shaking sensor, audio signal strength are fixed.According to the signal of Inspection and analysis, intelligent switch, after triggering wakes up up for the first time, can determine that duration is closed in timing, timing disconnects switch entrance resting state after completing.
If as it has been described above, selection spring type vibration switch is as induction apparatus, without power consumption when it is standby；Microprocessor uses STC15 series (providing more than 5 wake-up interrupts), and its dormancy is power consumption as little as 1 μ A.Therefore, by disposable 18650 property lithium battery (capacity is in terms of 1000mAh), intelligent switch can far surpass 10 years with standby 1000000 hours.Assume to have selected motor guard relay to export, and assume that its power consumption is 10mA, each action executing used time 1s, then can perform action 360000 times with the intelligent switch of above-mentioned battery, if action in a day 10 times, then intelligent switch can be with 36000 days, i.e. more than 4 years.If switch there is time-delay closing function, in the timing stage, the power consumption of microprocessor can than complete dormancy time slightly higher.
Intelligent switch of the present invention includes battery, induction apparatus, microprocessor and latch-in relay.The configuration achieves load high pressure forceful electric power and control the separation of low-voltage circuit, because employing the device of low energy consumption, changing one-shot battery and can use for many years.Induction apparatus then according to application environment and needs select, wherein preferred version is vibration switch, and it has simple in construction, and profile is little, and low cost facilitates the advantages such as use.

Detailed description of the invention
Intelligent switch as shown in Figure 1, it includes battery 10, touch sensor 20, microprocessor 30, DIP device 40 and magnetic latching relay 50, and all devices are placed in a housing.Battery provides the low-voltage control power needed for other devices, and when load does not works, microprocessor is in a dormant state, and relay is open-circuit condition.When after user soft-touch control, induction apparatus first produces an interrupt signal to microprocessor, it is waken up up from resting state.Microprocessor can immediately or induction apparatus signal is analyzed confirm after trigger relay so that it is Guan Bi.The relay of Guan Bi makes load circuit ON operation (such as: light illuminating lamp, starting electrical equipment etc.).Owing to relay has self-retaining function, being not required to the biggest electric current and power, microprocessor is then clocked into state (some microprocessor has timing arousal function, and therefore time status energy consumption is the lowest).When load circuit works (in microprocessor time status), user soft-touch control again, block system relay after microprocessor confirmation signal, make load circuit disconnect, microprocessor also immediately enters resting state.Without manual operation disconnecting consumers circuit, can automatically disconnect relay at the end of microprocessor timing, then intelligent switch enters dormancy power save mode.
In the embodiment shown in fig. 1, what relay selected is magnetic latching relay, and it can change electronic guard relay into.Induction apparatus uses touch sensor, it can change MEMS accelerometer or vibration switch (housing that only need to touch intelligent switch just can complete operation) into, gyroscope (roll-shell completes operation), audio sensor (by propaganda directed to communicate or voice recognition complete operation), the most common mechanical button or switch.In order to revise clocking value, the present embodiment adds DIP device 40.Certainly, timing duration can also be determined according to the signal checked from induction apparatus during switch connection, such as: touches number of times, the power of vibrations, the size of sound, key time durations length or button number of times etc..
Fig. 2 is shown that the intelligent switch of multiparty control, and it includes battery 10, microprocessor 30, electronic guard relay 51 and multiple vibration switch.Device is distributed in multiple housing, comprises battery 10, microprocessor 30, relay 51 and 1# vibration switch 21 in main casing 60.When intelligent switch is initial, microprocessor is resting state, relay is open circuit, when artificial touching main casing 60, vibration switch vibrations produce interrupt signal and wake up microprocessor up, and microprocessor can determine whether closing relay according to the power of vibrations and calculate Guan Bi duration.After relay Guan Bi, microprocessor starts timing, again can disconnect relay during touching main casing 60；Or after timing completes, automatically disconnect relay.
In the present embodiment, 2# vibration switch 22 and 3# vibration switch 23 is then respectively placed in other housings, and they connect (line can nor affect on performance up to tens of rice) with the 1# vibration switch in main casing 60 by wire.Three vibration switch (using the normally opened vibration switch of spring type) parallel with one another or series connection (using the normally closed vibration switch of ball-type) mode can access the same middle fracture of microprocessor.Certainly, three vibration switch can be respectively connected to the different interruption cause for gossip of microprocessor now the most independent control (microprocessor carries out independent analysis to three sensor signals).
The actual application of the many sensing arrangements of dispersed placement that the present embodiment provides at least includes following situation:
Multiple on-off control the same lamp in normal lighting (such as: the head of a bed in bedroom and doorway, upstairs and downstairs, two of gallery)；
When being inconvenient to control because socket is arranged on corner, the switch of this prolongation can be placed on place within reach on demand.
In actual applications, such as the control of socket, because socket is not easy to touching the most in corners, can cancel the induction apparatus in main casing 60, only retain an induction apparatus outside main casing, this induction apparatus can be from main casing number meter Yuan.The convenient operation of this structure, and low-voltage control power only it is connected to due to induction apparatus, therefore unlike the switch that tradition floor lamp uses, there is electric shock risk.
The various induction apparatus that can be used for the present invention noted above, because its characteristic difference needs to think better of structure and the installation site of intelligent switch in the specific implementation, fixed installation is such as just not suitable for the intelligent switch of gyroscope, and because using rotatable suspension mounting means (whole switch hangs or gyroscope is in independent suspension housing)；Preferably fixedly mount with the intelligent switch of touch sensor, and hang installation and increase operation easier；Overall with the intelligent switch of audio sensor or receiving sensor housing is also not suitable for being arranged on hidden corner.
In order to show clocking value, led display lamp, buzzer or display screen can be increased, to facilitate the time confirming automatically to disconnect relay.
When the present invention implements, except with in addition to DIP device amendment clocking value, it is also possible to increase data line interface, utilize smart machine (such as mobile phone, removable computer etc.) amendment more parameters (including clocking value, the sensitivity etc. of sensor).Even increase wireless communication module, it is achieved long-range management and control.
In actual application, additional timing indicating module and module etc. is set can be placed in main casing the housing that can also be placed in other protection induction apparatuss.
Below only with the design idea of several preferred embodiments explanation present invention; the selection of battery; the selection of latch-in relay; the selection of induction apparatus; the distribution selection etc. in multiple housings of parameter set-up mode, parameter display mode, the quantity of induction apparatus and the quantity of housing and each device all can gain enlightenment in describing the invention and change; if these amendments are in technical scope described in the claims in the present invention, then these amendments still belong to protection scope of the present invention.
