One article takes you to understand wired door and sensor of wireless door magnetism
[introduction] system of a few entrance guard is to be based on intelligence bus line and be the same as a systematic platform, the intelligent terminal of household can receive such intelligence can inspect machine of doorbell system doorway and management center conveniently, implementation caller is right tell, leave a message, take a photo as a souvenir and entrance guard function, make the first defense line of our family security.
System of a few entrance guard is to be based on intelligence bus line and be the same as a systematic platform, the intelligent terminal of household can receive such intelligence can inspect machine of doorbell system doorway and management center conveniently, implementation caller is right tell, leave a message, take a photo as a souvenir and entrance guard function, make the first defense line of our family security.
The door magnetism system in our life can divide sensor of magnetism of switch of the magnetism that it is the door, door commonly (detector) , 3 much comprise door magnetism warning apparatus. System of a few entrance guard is to be based on intelligence bus line and be the same as a systematic platform, the intelligent terminal of household can receive such intelligence can inspect machine of doorbell system doorway and management center conveniently, implementation caller is right tell, leave a message, take a photo as a souvenir and entrance guard function, make the first defense line of our family security. These still can deploy lock of intelligent response card, dactylogram at the same time, can achieve intelligent linkage, as warning apparatus of pace withdraw a garrison, open is corresponding lamplight or mode.
The working principle of sensor of wired door magnetism
The action that lives in switch of magnetism of the door in entrance guard system in intelligence is report of responsible door magnetic flux deny, electrify takes magnetism (close the door) , cut off the power degauss (open the door) , door magnetism installation is covered at the door and door on, switch is installed within house, cooperate to close the door automatically implement use, can bear commonly 150 kilograms pulling force.
Wired door magnetism is embedded installation more concealment, of inductive door window close, apply to woodiness or window of aluminium alloy door to give out wired often shut / often open switch signal. Door magnetism is to use exploration door, window, drawer to wait to whether be opened illegally or mobile. It is mixed by wireless emitter two parts comprise magnetism piece. Door magnetism system is mixed actually the principle such as bed magnetism is same. Basically be with door magnetism here exemple.
The working principle of sensor of wireless door magnetism
Wireless door magnetism is mix by wireless emissive module two parts comprise magnetism piece, there is two arrowheads place to reed of steel of a “ is in charge of yuan of parts of an apparatus of ” in wireless emissive module, maintain when magnetic body and the space that steel reed provides in 1.5 centimeters inside when, steel reed canal is in disconnect condition, when once magnetic body and steel reed provide detached space,exceeding 1.5 centimeters, steel reed canal can close, cause short circuit, call the police alarm signal transmits to lead plane while indicator light is bright. Sensor of wireless door magnetism uses the switch position of monitoring door, after no matter why be planted,when the door the reason is opened, sensor of wireless door magnetism emits specific radio wave instantly, remote call the police to lead plane.
The wireless alarm signal of wireless door magnetism can transmit 200 meters in open ground, 20 meters can be transmitted in average house, closely related to the environment all round. Wireless door magnetism uses the design that omit report commonly, when the door is shut it does not transmit radio signal, right now bad news report has a few microamper only, when the instant that the door is opened, transmit the wireless alarm signal that 1 second controls instantly, stop by oneself next, calculate the door to be opened all the time at this moment also won’t blast off again, this is to prevent catapult to blast off continuously cause in-house batteries n extinct and the influence calls the police, wireless door magnetism returns a design to batteries low voltage detects circuit, the voltage when batteries is low at 8 bend over, the LP glow diode of lower part can illume, need to change instantly at this moment A23 warning apparatus is special batteries, can affect the reliability that call the police otherwise.
Sensor of wireless door magnetism installs the upper part in door inside commonly, it divides composition by two: Minor part is permanent magnet, interior has a permanent magnet, use the magnetic field with constant generation, bigger is main body of wireless door magnetism, its interior has to often leave model canal striking spring, when leaning very nearly with canal striking spring when permanent magnet (be less than 5 millimeter) , sensor of wireless door magnetism is in working expect condition, it is certain to leave valve striking spring when permanent magnet after the distance, sensor of wireless door magnetism blasts off instantly include address encode and oneself identification code (namely data is piled up) the signal of high frequency radio of 315MHZ, receive board whether is passing the address code that identifies this radio signal to judge namely same call the police of the system, next according to oneself identification code (namely data is piled up) , it is magnetism of which wireless door calls the police certainly.
The application of door magnetism system between real life
This is magnetism of a common dark door fitting pattern on market, do not take magnet of the Tibet inside the one aspect of the matter of electrical wiring, the low end of live wire is in-house Tibet has canal striking spring to wait for yuan of parts of an apparatus, when magnet is adjacent, electrical wiring output closes signal, when magnet is far from, two electrical wiring output open circuit signal. The one aspect of the matter of not live wire installs the coping in the door, the outfit of one aspect of the matter of live wire is on doorcase. When the door has shut, two decorous good jackknife are adjacent. There still are a few magnetisms on market is quadrate, apply to bright outfit circumstance, use on door window.
Which kinds of characteristic door magnetism can use at entrance guard system:
The output when the door is shut closes signal (measure resistor to be with avometer 0) , open circuit signal is inputted when the door is opened. (measure resistor infinity with avometer)
The door magnetism of on market 90% is this kind of character, still have a few door magnetism character as it happens is contrary, perhaps close signal and open circuit signal have output (3 lines, one is communal, additionally two cooperate common thread to be outputted respectively open circuit and close signal, when using, choose among them a pair can, a of disagreement character unused) . The door magnetism that some report lock up also is such, for example: 5 wires report inserts a lock (2 are power source, 3 are door magnetism line) , 8 wires report inserts a lock (not only output of the magnetism that take the door, and take cylinder position position to output) , unused line unused can.
In software when real time monitoring, can see every door present condition is a move still is closing. Can cooperate entrance guard controller to enable the door to be entered illegally (the legitimate operation that did not brush card to perhaps press button, and the door was opened, kick leaves or lever for example) call the police. Can cooperate entrance guard controller to enable the door to was not shut for long call the police etc.
If do not need the entrance guard system of these a few functions, need not receive door magnetism. If need these a few functions, the door magnetism that receives door magnetism controller inputs a dot to go up, need not distinguish losing. If a large Duomenmen bans a system, only a few doors use these a few functions of door magnetism, aspects of other door magnetism input undertake with lead short receive, avoid generation by accident alarm signal.
The intelligent household system of content couplet net feels interactive layer, network to transmit layer and application to serve a composition by domestic environment. Domestic environment feels interactive layer to be comprised by all sorts of sensor node that contain wired or wireless function, of the collection that basically realizes domestic environment information, master condition get and of caller identity feature type; Network transmission layer basically is in charge of residing what an information and director dominate news to transmit; Applied service layer is in charge of controlling household establishment or application serves interface.
Sensor of magnetism of the door in door magnetism system belongs to the domestic environment that we say to feel interactive layer namely. The English name of wireless door magnetism is Doorsensor, general gangster enters residential method to have two kinds from the door: It is the key that steals host, open the door; 2 it is tool of have the aid of levers the door. No matter the gangster is to use why to plant the method is entered, he must push residential door. Once bandits is pushed,open the door, the door and doorcase are sure to produce shift, door magnetism and magnet also produce displacement at the same time, (electric wave) signal immediateness shoots lead plane, lead plane resounds call the police telephone number that dials 6 groups to be set beforehand. Rise to live in the life thereby more the safety that intelligence changes defends. Ensure the safety of domesticity and belongings.
