Detailed description of the invention

Various exemplary embodiments will be more fully described referring to accompanying drawing below, show some examples in the accompanying drawings The property shown embodiment.But, this utility model concept may embody in many different forms, and should not explain Be limited the exemplary embodiments illustrated in this article.Specifically, it is provided that these exemplary embodiments make This utility model is the most detailed and complete, and will fully pass on this utility model concept to those skilled in the art Category.In all accompanying drawings, size and the relative size in Ceng Ji district can be lavished praise on oneself in order to understand.Similar numeral All the time like is indicated.

Welcome's system of this utility model embodiment is by the electric capacity of condenser type detection module detection capacitive sensing point It is worth using as the control started or close.Condenser type detection module is become by the capacitance of detection capacitive sensing point Change to wake up microcontroller up, make microcontroller that welcome's module to be controlled.Follow-up will illustrate further this The component details of welcome's system of utility model and start thereof.

Refer to the block diagram that Fig. 1, Fig. 1 are welcome's systems of this utility model embodiment.Welcome's system 1 Including capacitive sensing point S1, condenser type detection module 11, microcontroller 12, welcome's module 13 and power supply mould Block 14.Condenser type detection module 11 coupling capacitance induction point S1, microcontroller 12 is coupled to condenser type detection mould Block 11, welcome's module 13 is coupled to microcontroller 12.It addition, condenser type detection module 11, microcontroller 12 And welcome's module 13 is coupled to power module 14.

In this utility model embodiment, capacitive sensing point S1 is the Copper Foil of a connection condenser type detection module 11. But, can also substitute with other metallic conductors in other embodiments, this utility model is not with electric capacity sense The aspect of S1 should be put as restriction.It will be further appreciated that, the capacitive sensing point S1 of this utility model embodiment Sheet metal or transparent conductor plate can also be coupled to further to form an electric capacity according to manufacturer or user Induction zone, improves condenser type detection module 11 sensing range.For example, when the manufacturer of welcome's system 1 When manufacturing, it would generally make the shell with various moulding by metal material or transparent conductor plate. Therefore, capacitive sensing point S1 can be connected by manufacturer with the shell of welcome's system 1, makes welcome's system 1 energy Enough monolithic case is all formed capacitive sensing district, and improves the detection range of condenser type detection module 11.Even, Above-mentioned capacitive sensing point S1 itself can be exactly shell metal material therein or transparent conductor plate.

More carefully saying, condenser type detection module 11 can routinely detect the letter that capacitive sensing point S1 is transmitted Number to read induction meter numerical value, induction meter numerical value is that capacitive sensing point S1 is electrically charged (or electric discharge) time or secondary Number.Induction meter numerical value can represent the capacitance information of capacitive sensing point S1, and in other words, induction meter numerical value has There is the information whether external environment near capacitive sensing point S1 changes.Condenser type detection module 11 is in dormancy Can judge under control model that whether induction meter numerical value is more than the sense counter higher limit preset or less than the sense preset Lower limit should be counted, that is determine whether that event to be detected occurs (the most doubtful car door is opened or is closed). When induction meter numerical value is more than the sense counter higher limit preset or is less than the sense counter lower limit preset (separately A kind of application also can reversely be defined as when count value falls in default sense counter upper lower limit value), electric capacity Formula detection module 11 can produce wake-up signal to microcontroller 12, to be waken up up by microcontroller 12, and makes to meet Guest's system 1 enters standard capacitance detection pattern.It addition, condenser type detection module 11 detects pattern in standard capacitance Time, it is the most only to send the induction meter numerical value of reading to microcontroller 12.

Microcontroller 12 most of the time is in dormancy control model, and event to be detected just meeting only occurs Enter standard capacitance detection pattern, that is microcontroller 12 most of the time is power saving resting state, and only The time having few part is standard capacitance detection pattern (the most very power saving).When microcontroller 12 enters standard After capacitance detecting pattern, the sense counter of the capacitive sensing point S1 that condenser type detection module 11 is read can be received Value, and the sense counter higher limit preset according to this induction meter numerical computations point S1 of capacitive sensing instantly is with pre- If sense counter lower limit, then by capacitive sensing point S1 preset sense counter higher limit with preset sense Lower limit should be counted store to condenser type detection module 11, for condenser type detection module 11 in dormancy control afterwards As the benchmark determining whether event to be detected under molding formula.It addition, microcontroller 12 is examined in standard capacitance Also can judge the situation of environmental change according further to the induction meter numerical value of capacitive sensing point S1 under survey pattern, and And produce corresponding indication signal accordingly.The sense counter that capacitive sensing point S1 presets is calculated at microcontroller 12 Higher limit and the sense counter lower limit preset, and after producing corresponding indication signal, that is to electric capacity Induction point S1 carries out a standard capacitance detection, and microcontroller 12 welcome's system 1 can enter to dormancy control model (that is entering power saving resting state).

It should also be noted that owing to condenser type detection module 11 cannot judge occuring as of event to be detected exactly Capacitive sensing point S1 senses environmental change or the misoperation caused by garbage, interference etc., therefore to be checked When survey event occurs, microcontroller 12 needs to be waken up, and further capacitive sensing point S1 is carried out standard Capacitance detecting.When microcontroller 12 judges that capacitive sensing point S1 senses environmental change, then microcontroller 12 meeting Produce indication signal to the back-end circuit of welcome's system 1.If event to be detected is by garbage or dry The misoperation caused such as disturb, then microcontroller 12 can then be again introduced into dormancy control model.

Welcome's module 13 is controlled by the indication signal of microcontroller 12.It is to say, when welcome's module 13 receives Start or close the function that had during the indication signal produced to microcontroller 12.Implement at this utility model In example, welcome's module 13 can be shadow module and/or sound module or other FX Module (examples Such as dry ice, smog output module etc.).It addition, power module 14 in order to provide welcome's system 1 inner member, The element being attached thereto or the driving power supply of module.In other words, power module 14 provides condenser type to detect mould The driving power supply of block 11, microcontroller 12 and welcome's module 13.In this utility model embodiment, power supply Module 14 provides the driving power supply of the driving voltage (for example, mercury electrode) of 3 volts (V) to welcome's module 13, and by condenser type detection module 11 to detect the detection mode of induction meter numerical value, it is possible to realize low merit Consumption.But, power module 14 also can provide different voltage to condenser type detection module 11 or microcontroller 12. In other words, welcome's system 1 of this utility model embodiment can consume less than or equal to 5 microamperes (5 μ A) Electric current.It is noted that this utility model also because of microcontroller 12 at condenser type detection module 11 in inspection When the event that measures produces, just enter further into standard capacitance detection pattern, that is microcontroller 12 major part The power saving resting state that time is power saving dormancy, and to be standard capacitance detect pattern the time only having few part, It is possible to reduce the purpose of power consumption.

Then, will introduce further for the details of condenser type detection module 11.Condenser type detection module 11 In order to detect the induction meter numerical value of capacitive sensing point S1, to produce wake-up signal to microcontroller 12.Please be simultaneously It it is the interior block diagram of the condenser type detection module 11 of this utility model embodiment refering to Fig. 1 Yu Fig. 2 A, Fig. 2 A. Condenser type detection module 11 includes capacitance induction apparatus 111 and event diagnosis apparatus 112 to be detected.Capacitance sense Answering device 111 to be coupled to capacitive sensing point S1, event diagnosis apparatus 112 to be detected is coupled to capacitance induction apparatus 111. Microcontroller 12 is coupled to capacitance induction apparatus 111 and event diagnosis apparatus 112 to be detected.

More carefully saying, capacitance induction apparatus 111 is in order to read and to record the sense counter of capacitive sensing point S1 Value.Capacitance induction apparatus 111 is to send induction meter numerical value to microcontroller under standard capacitance detection pattern 12, and be that induction meter numerical value is sent to event diagnosis apparatus 112 to be detected under dormancy control model.Microcontroller Device 12 just can receive induction meter numerical value under standard capacitance detection pattern, does not connects under dormancy control model Receive induction meter numerical value.Event diagnosis apparatus 112 to be detected can't receive induction meter under standard capacitance detection pattern Numerical value, and under dormancy control model, only just can receive induction meter numerical value.

Event diagnosis apparatus 112 to be detected can receive and record microcontroller 12 foundation under standard capacitance detection pattern The sense counter higher limit of the capacitive sensing point S1 that induction meter numerical value calculates and sense counter lower limit, and Then can judge under dormancy control model that whether the induction meter numerical value coming from capacitive sensing point S1 is more than capacitive sensing Put the sense counter higher limit that S1 presets or the sense counter lower limit preset less than capacitive sensing point S1, that is Relatively induction meter numerical value and the sense counter higher limit preset, and compare induction meter numerical value and the sensing preset Counting lower limit.If induction meter numerical value is more than sense counter higher limit default for capacitive sensing point S1 or less than electricity (another kind of application also can reversely be defined as when capacitive sensing point to hold sense counter lower limit default for induction point S1 When the count value of S1 falls in default sense counter upper lower limit value), event diagnosis apparatus 112 the most to be detected produces Wake-up signal is to microcontroller 12, to wake up microcontroller 12 up, makes welcome's system 1 enter from dormancy control model Pattern is detected to standard capacitance.

It should also be noted that on another kind is applied, condenser type detection module 11 can be sentenced under dormancy control model Whether disconnected induction meter numerical value is less than the sense counter higher limit preset or more than the sense counter lower limit preset, To determine whether this event diagnosis apparatus 112 to be detected produces wake-up signal to microcontroller 12.In this kind of application On, if the induction meter numerical value of previous capacitive sensing point is more than the sense counter higher limit preset, and electricity at present Hold the induction meter numerical value of induction point less than the sense counter higher limit preset, then it represents that external environment is Change；Or, if the induction meter numerical value of previous capacitive sensing point is less than the sense counter lower limit preset, And the induction meter numerical value of capacitive sensing point is more than the sense counter lower limit preset at present, then it represents that external Environment is varied from.Briefly, whether condenser type detection module 11 is more than pre-according to previous induction meter numerical value If sense counter higher limit or less than preset sense counter lower limit, determine use preset induction meter Number higher limit or default sense counter lower limit compare with current induction meter numerical value, to judge whereby Event to be detected whether is had to occur.

Optionally, incorrect (such as with sense counter lower limit possibility in order to avoid sense counter higher limit Indoor and outdoor or night on daytime ... wait the transition of external environment), and have the generation of misoperation, event to be detected Module 112 except the sense counter higher limit whether preset more than capacitive sensing point S1 according to induction meter numerical value or Outside the sense counter lower limit preset less than capacitive sensing point S1 produces wake-up signal, it can also be every A period of time generation wake-up signal, such as 5 seconds, periodically to wake up microcontroller 12 up.Then, microcontroller After 12 couples of capacitive sensing point S1 carry out a standard capacitance detection, that is calculate up-to-date capacitive sensing point S1 Preset sense counter higher limit with preset sense counter lower limit, and produce corresponding indication signal it After, microcontroller 12 can enter dormancy control model, that is returns to power saving resting state.

In step S305, complete to recalculate under standard capacitance detection pattern and more at microcontroller 12 After the determination range that new induction meter numerical value is corresponding, then it is again introduced into dormancy control model, and performs step S306, to wait that the wake-up signal of next event diagnosis apparatus 112 to be detected is started.

Step S306 (refers to shown in Fig. 5 B), if event diagnosis apparatus 112 to be detected judges capacitive sensing The sense counter higher limit that the induction meter numerical value of some S1 is preset after updating and the sense counter lower limit preset In the range of, the most persistently carry out step S306 and detect；On the other hand, if event diagnosis apparatus 112 to be detected is sentenced The induction meter numerical value that power-off capacitance induction apparatus 111 receives exceed the sense counter higher limit preset after renewal with Time between the sense counter lower limit preset, enter step S307.But, the step of subsequent step S308～310 Suddenly being essentially the same as step S303～305, its difference is only that in step S309a microcontroller 12 is produced Raw indication signal is shutdown signal, and in order to welcome's module 13 of unlatching to be closed, remaining repeats no more in this.

Please refer to Fig. 2 B be that this utility model embodiment is in building welcome gate refering to Fig. 6, Fig. 6 Application schematic diagram.Similarly, welcome's system 1 of this utility model embodiment also apply be applicable to building (such as For convenience store, restaurant, household etc.) building gateway 3 on.More carefully say, in normal lower big When door 31 (for example, metal gate) is closed, the induction meter numerical value that capacitance induction apparatus 111 senses is in presetting Sense counter higher limit with preset sense counter lower limit in the range of.If event diagnosis apparatus 112 to be detected is sentenced Power-off holds the induction meter numerical value of induction point S1 under default sense counter higher limit and default sense counter Between limit value, the most persistently it is read out and notes down；On the other hand, if event diagnosis apparatus 112 to be detected judges electricity The induction meter numerical value that capacitance induction apparatus 111 receives is beyond the sense counter higher limit preset and the induction meter preset When counting the scope of lower limit, event diagnosis apparatus 112 to be detected produces wake-up signal by wakeup unit 1122 to be made micro- Controller 12 is entered standard capacitance detection pattern by dormancy control model.

Similarly, in standard capacitance detection pattern, microcontroller 12 is read greatly by capacitance induction apparatus 111 The induction meter numerical value of capacitive sensing point S1 when door 31 is opened, recalculate accordingly and update at gate 31 away from The sense counter higher limit that during welcome's system 1, capacitive sensing point S1 presets and the sense counter lower limit preset.And At the same time, microcontroller 12 is judged as that gate 31 is opened, and produces unlatching signal correspondence unlatching welcome's module 13。

Complete under standard capacitance detection pattern, recalculate and update induction meter numerical value at microcontroller 12 corresponding Determination range and after producing command signal (above-mentioned unlatching signal), then be again introduced into dormancy and control mould Formula, to wait that the wake-up signal of next event diagnosis apparatus 112 to be detected is started.

Such as arrangements for automotive doors and the application of meeting pedal of Fig. 4, when gate 31 or arrangements for automotive doors 20 are opened, meet Guest's system 1 waits that the wake-up signal that condenser type detection module 11 produces enters to wake up microcontroller 12 up too Standard capacitance detection pattern carries out recalculating and corresponding generation command signal of induction meter numerical value determination range After (being such as turned on and off signal), it is again introduced into dormancy control model to save power consumption.

Comprehensive the above, the welcome's system proposed by this utility model embodiment, it is possible to effectively solve The Related product situation positioning easy misalignment on switch judges in the past, and further with the electricity of power saving The detection of appearance formula and microcontroller implementation low-power consumption.On the other hand, need to pass through compared to orthodox car welcome's system The complicated installation procedure of automobile power source output (12V), described welcome's system i.e. can be transported merely with mercury electrode Turn.It is to say, this utility model embodiment welcome's system replace old on the market need arrange in pairs or groups infrared ray, The transmitting of ultrasound wave, magnetic clasp sensing receives sensing element and makes, except reduce also save in addition to cost numerous and diverse specially Industry personnel carry out the installation of car body bracing wire.Therefore, described welcome's system saves the time that user carries out installing And car fills the cost of transformation and the risk avoiding circuit to cock off, and welcome's function can be reached.Furthermore, this reality By novel welcome's system for after-mounting state, either also can like with user easily in installation or replacing Carry out.

It is noted that the capacitive sensing point of described welcome's system can be the metal dots on PCB, and enter one Step ground reduces cost.It addition, the induction sensitivity of the metal dots on printed circuit board (PCB) can be adjusted, with more Accurately sense whether have object proximity or away from.

Multiple person, when this utility model is installed on the gate of building or window, also can be as anti-theft device Application；That is when door and window is unlocked, welcome's system i.e. can respond start, reaches caution effect.

The above, only specific embodiment of the utility model, but feature of the present utility model is not limited thereto, Any those skilled in the art are in field of the present utility model, it is clear that change or modification, all contain In the scope of patent protection of this case.
