Embodiment
In order more to be expressly understood technology contents of the present invention, the special following examples of lifting specify.
See also shown in Figure 1ly, be passive structural representation of the present invention from the capacitation wireless door magnetism device.
In one embodiment, this passively comprises from the capacitation wireless door magnetism device:
Elastic arm supports and is located on the door, and is fixed on the doorframe through a stationary shaft, and described elastic arm rotates along described stationary shaft with the switch of door,
Generator of electric energy is connected in described elastic arm, and under the driving that elastic arm rotates, produces electric current,
Central processing module is connected in described generator of electric energy,
The warning trigger switch is connected in described central processing module, and it breaks off with closed to rotate control by described elastic arm, and
The alerting signal sending module is connected in described central processing module, and under the control of central processing module, sends alerting signal to exterior terminal.
Wherein, described central processing module is a ultra low-power microcontroller.Described alerting signal sending module is little power consumption communication module.
In a kind of more preferably embodiment, as shown in Figure 2, the trigger position of described warning trigger switch is positioned at the centre position of the rotational travel of described elastic arm drive electricity generator.The rotational travel of described elastic arm drive electricity generator is 40 degree rotation displacements.
In a kind of preferred embodiment, described wireless door magnetism device comprises housing, and described generator of electric energy, single-chip microcomputer, warning trigger switch and alerting signal sending module all are arranged in the described housing, and described elastic arm is arranged at outside the housing.One end of the stationary shaft of described elastic arm is arranged in the described housing, and the other end extends to outside the housing, and described elastic arm is movably connected on the end that described stationary shaft extends housing.Described wireless door magnetism device is fixed on the doorframe through described housing.
In an application of the invention, of the present invention passively mainly form by following components from the capacitation wireless door magnetism device:
A, little power consumption MCU, it is the software kernels process chip of door magnetic.
B, induction of signal switch, it is triggered by elastic arm with power generator, but the position that this switch is triggered is positioned at the be triggered centre position of actuating length of power generator.Can guarantee that like this during little power consumption MCU and ZIGBEE communication module acquisition electric energy, detecting alarm switch exactly is transformed into open-circuit condition from short-circuit condition, perhaps is transformed into the process of short-circuit condition by open-circuit condition.Thereby when making MCU obtain the duration of work of power supply, can accurately judge the open the door action and the action of closing the door, avoid taking place at closing time false alarm.
C, the little power consumption communication module of ZIGBEE, in order to when door is opened, the little power consumption communication module of MCU control ZIGBEE sends alerting signal according to the local communication protocol form at a high speed to end host.In the practical application, the little power consumption communication module of this ZIGBEE adopts the TCM 300/STM 300 power consumption communication moulds of German EnOcean company.Its technical characterictic is: 868MHz (R&TEE) and 315MHz (FCC); Possess processor and control function; The peripheral equipment that can simplify; Can programme to application-specific through API, have energy and management of sensors function, and have WDT, voltage limit for height device, predetermined inductive device and the internal memory etc. of super low-power consumption.
D, power generator, its door are when being opened or close, and the mechanical action that is produced by door magnetoelasticity arm change in location drives the generation immediate current, carry out the short time to, little power consumption MCU and the little power consumption communication module of ZIGBEE and supply power.It can change the kinetic energy of button into electric energy, have durable, as to be excused from a college course reason advantage, and its volume is tiny, meets the design of microswitch button.
E, shell mechanism spare are easily installed in the narrow and small position, space of doorframe.
With of the present invention passive from the capacitation wireless door magnetic be installed on the doorframe or door on after.The elastic arm that stretch out on the direction next door on the door magnetic is to rotate along axially carrying out certain angle.Inner by spring control, elastic arm rotates about 40 degree to door place direction when opening the door; The pressure effect of door turns to forward and the door magnetic back side belongs to same plane because elastic arm receives at closing time.At the rotation displacement that opens the door or elastic arm will form about 40 degree under the action effect of contained spring and door at closing time.Utilize the action of this micro-mechanical shift to drive power generator just and produced electric energy, and also obtained the step switch amount of opening the door or closing the door simultaneously.Thereby judge the action of opening the door exactly, the false alarm of shaking generation of avoiding closing the door takes place.
It is compared with traditional door magnetism device that comprises two parts of a magnet and magnetic stripe from the capacitation wireless door magnetism device to have adopted this invention passive; No longer need magnet; Also without any need for power supply, but utilize elastic arm and generator of electric energy to cooperate, produce electric energy by the kinetic energy that opens the door; And, realize the function of wireless door magnetic to the central processing module power supply.The design concept that it is different from existing any wireless door magnetism device fully is a kind of wireless door magnetism device that utilizes self generating.Thereby, can not only farthest reduce door magnetism device required space is installed, simplify installation steps, energy-conserving and environment-protective, and this is passive simple in structure from the capacitation wireless door magnetism device, with low cost, and range of application is comparatively extensive.
In this instructions, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, instructions and accompanying drawing are regarded in an illustrative, rather than a restrictive.
