The present invention relates to devices and methods of detecting a door/window status and more particularly to a device and method of detecting a door/window status and determining the door/window status by detecting the strength of a signal.
Due to economic development and technological advancement, there is an increasingly great demand for door/window protection as far as home safety is concerned. In this regard, conventional ways of detecting a door/window status fall into the following categories: vibrational sensing, switch-based sensing, and mechanical sensing.
Take vibrational sensing as an example, it is predisposed to errors because of any external force arising from a wrong collision, for example. As a result, vibrational sensing is unreliable and unpractical. Taiwan Patent M373561 discloses a magnetic spring-based switch, wherein a leaf spring made of iron is magnetically attracted to a magnet to thereby confirm that the switch is turned off; however, the security of the switch can be undermined whenever a sensing end thereof is magnetically attracted to a magnet such that the sensing end and the magnet move together. Likewise, Taiwan Patent 580177 discloses that a V-shaped spring serves as a switch, wherein a user has to insert the V-shaped spring anew in each instance of operation; as a result, in the situation where it is necessary to turn on and turn off the switch very often, the V-shaped spring lacks ease of use.
In view of the aforesaid drawbacks of the prior art, US 20070233407 discloses detection of magnetic changes, wherein a coil is wound round one side of a door/window such that the coil generates a magnetic force change for determining whether the door/winder is opened or shut; however, US 20070233407 has drawbacks as follows: although it is not necessary for the coil of US 20070233407 to be mounted anew, it is more intricate to mount the coil and a sensing device of US 20070233407 on the door/window than the magnetic spring-based switch of Taiwan Patent M373561.
In view of the aforesaid drawbacks of the prior art, it is an objective of the present invention to provide a device and method of detecting a door/window status and determining the door/window status and position through a change in a sensing signal, so as to further enhance home safety.
Another objective of the present invention is to provide a device and method of detecting a door/window status, comprising an accelerometer and a magnetic force gauge whereby the status detection is rendered precise, so as to further enhance home protection.
In order to achieve the above and other objectives, the present invention provides a device of detecting a door/window status, comprising: a signal generating unit disposed beside a door/window to generate a position signal; and a signal sensing module disposed opposite the signal generating unit and comprising a three-axis accelerometer, a three-axis magnetic force gauge and a microcontroller, wherein the microcontroller reads the position signal generated from the signal generating unit and detection signals generated from the three-axis accelerometer and the three-axis magnetic force gauge while the door/window is operating to thereby determine the position and status of the door/window, thereby enhancing home safety.
In order to achieve the above and other objectives, the present invention further provides a method of detecting a door/window status, comprising the steps of: providing a signal generating unit disposed beside a door/window to generate a position signal; and providing a signal sensing module disposed opposite the signal generating unit and comprising a three-axis accelerometer, a three-axis magnetic force gauge and a microcontroller, wherein the microcontroller reads the position signal generated from the signal generating unit and detection signals generated from the three-axis accelerometer and the three-axis magnetic force gauge while the door/window is operating to thereby determine the position and status of the door/window, thereby enhancing home safety.
