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 the structural representation of monomer wireless door magnetism device of the present invention.
In one embodiment, this monomer wireless door magnetism device comprises: elastic arm, warning trigger switch, central processing module, alerting signal sending module and housing.Described elastic arm supports and is located on the door, and has a stationary shaft, and this elastic arm rotates along described stationary shaft with the switch of door; Described warning trigger switch is connected in described elastic arm, and it breaks off with closed to rotate control by described elastic arm; Described central processing module is connected in described warning trigger switch; Described 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; Described central processing module, warning trigger switch and alerting signal sending module all are arranged in the described housing; This housing is fixed on the doorframe; One end of the stationary shaft of described elastic arm is arranged in the described housing; The other end extends to outside the housing, and described elastic arm is movably connected on the end that described stationary shaft extends housing.
