Description

A kind of door and window magnetic

Technical field

The present invention relates to safety precaution, the door in Smart Home field, window alarm for opening, modal application includes burglar and invades warning, and infant climbs window warning etc.

Background technology

Door and window magnetic is the alarm for opening for door and window, and it generally includes two independent parts: magnetic induction part and magnet. Simplest magnetic induction part is containing only there being a tongue tube, and it is a mechanical switch, magnet closer or far from conversion time realize the conversion of on/off. During use, magnetic induction part and magnet are separately fixed at two relatively-movable parts (such as doorframe and door, window frame and window, or two panels all moveable windows etc.) of door and window, are used for judging whether door and window closes. Switching signal can receive other equipment either directly through wire, triggers and reports to the police; Or increase microprocessor (MCU) in magnetic induction part, by the even various wireless module remote transmission of relay to other equipment after making signal inverted. Except tongue tube, magnetic induction part can be replaced with other elements, as: Hall element.

On market, existing door and window magnetic provides only two states: on an off, its application is just embodied in whether door and window is in specific position (be often referred to and whether close), this is enough use for the house gate (and part window) of common opening and closing in a rotative pattern, as long as door and window is opened a small gap (size in gap depends on the operating distance of magnetic induction part and magnet being generally 2 centimetres) by closed mode and is just reported to the police. But, for common sliding rail formula window (also comprising some sliding windows with radian), in order to air circulates, window would generally open a part (gap is often beyond 2 centimetres), if window magnetic is contained in window Guan Bi place, once ventilation of windowing, just reports to the police; And if be arranged on ventilate open position, then can report to the police on the contrary during Window closing. Therefore, disclosed window magnetic cannot take into account the demand ventilated with security alarm currently on the market.

Summary of the invention

It is an object of the invention to provide a kind of convenient ventilation, it is to avoid wrong report, and indicate the window magnetic of opening degree, this window magnetic can be also suitably used for various sliding rail formula door (so also just become a magnetic, herein, Men Ci, window magnetic and door and window magnetic do not distinguish, and all represent the object of indication of the present invention).

The scheme that the present invention realizes is to arrange at least two magnetic induction part (tongue tube, Hall element etc.) in the magnetic induction part of door and window magnetic, these magnetic induction parts are separated from each other in physical space, the signal produced is separate, after installation, the active position from magnet is different, the position etc. when they can correspond respectively to the position of Window closing, window opens different gap. It is preferred that the distance between sensing element is at 2 centimetres (operating distance of conventional magnetic induction part and magnet) to 15 centimetres (safe slits that human body cannot pass through, with reference to the accepted value of echlette alarm beam separation). It is preferred that magnetic induction part arranges two tongue tubes, be separated by between the two 10 centimetres (window moving direction coordinates), one of them tongue tube when window closes with magnet effect, namely show that window is of completely closed during this first tongue tube sensing; When window is gradually opened, first this first tongue tube lose induction, it was shown that window has already turned on, simultaneously because second tongue tube is also in non-sense state, the state in this process all represents that window has opened one gap; When window continues to move along second tongue tube entrance sense state, represent that window opens the ventilation opening set; If continuing on window, second tongue tube loses induction, then can provide alarm signal. In another embodiment, two tongue tubes are accessed the different input ports of microprocessor, then during the sensing of different dry reed pipe, microprocessor is by signals different for output, these signals can by wired or be wirelessly sent to other system (such as alarm host machine, remote server, or the various smart machines such as mobile phone). Further, when window is moved by ventilation state (second sensing element convert non-inductive state to from sense state to time), microprocessor clocks, if window is not turned off (first sensing element returns to sense state) within the time set, then provides warning. So can avoid occurring wrong report within the of short duration time closing window.

The another embodiment that the present invention proposes is: arrange at least two sensing element in sensing part, and they separation distances on window moving direction meet following two condition: when magnet is from afar when two sensing elements are close, magnet always first and spatially closer to sensing element effect, it is achieved State Transferring; (herein referring to the coordinate figure on moving direction) when magnet is between two sensing elements, one of them sensing element another sensing element before disengaging effect first has been enter into effect (namely having at least a sensing element to be in the sphere of action of magnet). Considering that window moves the speed of operation and the operating distance of existing magnetic induction part, in the present embodiment, the preferably distance of two sensing elements is 5 millimeters-2 centimetres. So, once define the original state of system, it is possible to judge the moving direction of window, namely may determine that the position of window. That is, the system that a traditional sensing element joins a magnet may determine that two location status, and two sensing elements here are joined a magnet and be may determine that 3 location status, judge if to increase more space, it is possible to continue in the direction of movement to increase sensing element. Another increases the quantity identifying that the implementing method of position is to increase magnet, and sensing part only arranges two sensing elements, so can reduce the build of sensing part, application more convenient to install. It is preferred that the spacing that magnet prolongs moving direction arrangement is 5-10 centimetre.

Detailed description of the invention

Window magnetic as shown in Figure 1, it includes two independent parts: magnetic induction part 1 and magnet 5. Be provided with two sensing elements in magnetic induction part, respectively sensing element 3 and sensing element 4, they be open type tongue tube (magnet near time Guan Bi, magnet is away from then opening). Tongue tube 3 and tongue tube 4 are at a distance of 10 centimetres (operating distance of tongue tube and magnet is 2 centimetres), and their respective independent signal is respectively connected to microprocessor (MCU) 2. After system is installed, magnet 5 can prolong in Fig. 1 direction of arrow relative movement (according to window arrangement and installation site in practical application, magnet and magnetic induction part have at least body one by one to move), when magnet 5 is in the active position of tongue tube 4, tongue tube 4 closes, and tongue tube 3 is opened a way simultaneously; When magnet 5 prolongs after the direction of arrow moves and make itself and tongue tube 4 distance more than 2 centimetres, tongue tube 4 is opened a way, and at this moment tongue tube 3 is still opened a way; It is close that magnet 5 continues to move to tongue tube 3, and between the two from when reducing arrival 2 centimetres, tongue tube 3 closes. The present embodiment is when practical application, and microprocessor can pass through to judge the state that the state of two tongue tubes judges window: when tongue tube 4 closes, window is as closing, and window magnetic is not reported to the police; When tongue tube 3 closes, window is ventilation state, and window magnetic is not also reported to the police; When tongue tube 3 and 4 is all opened a way, system alarm. In order to eliminate window from close and ventilation two states between change time wrong report, can increasing delay judgement, namely door magnetic determines and does not report to the police after two tongue tubes are all opened a way at once, and is to wait for certain time, seeing if there is one of them tongue tube Guan Bi, just providing warning if still not closing. Preferably the waiting time can set that to be 1 second, and this time allows window normally mobile 10 centimetres, and burglar is not easy to pass through window.

In embodiment shown in Fig. 2, the tongue tube 3 and the dry reed tube 4 that arrange inside magnetic induction part 1 lean on closer, and their signal is each respectively connected in microprocessor 2. When magnetic induction part 1 by the place away from #1 magnet 5 prolong the direction of arrow move time, following state will occur successively: tongue tube 3 enters sense state, tongue tube 4 enters sense state, and tongue tube 3 loses induction, and tongue tube 4 loses induction. In the present embodiment, it is crucial that the distance between two tongue tubes, it must assure that tongue tube 3 tongue tube 4 before losing induction comes into sense state, and the signal in such window magnetic is analyzed through microprocessor 2 and just be can determine that magnetic induction part 1 is to move along the direction of arrow. Same reason, if magnetic induction part 1 is reverse movement, to occur successively: tongue tube 4 enters sense state, tongue tube 3 enters sense state, tongue tube 4 loses induction, tongue tube 3 loses induction, same because tongue tube 3 comes into sense state before tongue tube 4 loses induction, and therefore system can determine that magnetic induction part 1 is for reverse movement.

As shown in Figure 2, if only using #1 magnet 5 when installing and using, and when Window closing the position of magnet 5 just corresponding tongue tube 3, so this magnetic allow window to move to magnet 5 corresponding to the position of tongue tube 4, (tongue tube 4 is in sense state, tongue tube 3 can be sense state or non-inductive state) and do not report to the police, make tongue tube 4 lose induction if continuing to move to window, then door magnetic provides alarm signal. This application only allows window to open about 2 centimetres (this value depends on the operating distance of magnet and sensing element and the distance between two sensing elements) to ventilate and do not report to the police. In order to increase ventilation effect, add #2 magnet 6 especially, it is assumed that magnet 6 is separated by 10 centimetres from magnet 5, then the ventilation gaps that window allows can increase to about 12 centimetres, and namely window reaches the position that magnet 6 can also act on tongue tube 4. In this embodiment, system can accurately judge that two sensing elements and two magnets are in the orientation of moving direction, namely the degree that window is opened is judged, including: window closes, window is open within 2 centimetres, window is open at the scope of 2-10 centimetre, and window is open at 10-12 centimetre and window is opened more than 12 centimetres (this state is typically set at alarm condition).

For the embodiment shown in Fig. 2, increase magnet and adjust the distance between magnet, it is possible to realizing the adjustment of different ventilation effect easily.
