There can be the chip of the information processing function for microprocessor, CPU etc., for the internal wiring on-off shape according to sensing unit 101
State controls information sending module 1052 and sends warning message to server 11 or mobile device 12.For example, working as sensing unit 101
Internal circuit disconnects, and in the present embodiment, control module 1051 controls information transfer module 1052 and transmits warning message to clothes
Perhaps mobile device 12 notifies the monitored place such as user's door, window illegally to be opened server 11 or user at this time to business device 11
Mobile device 12 show the above warning message；When the conducting of 101 internal circuit of sensing unit, in the present embodiment, mould is controlled
Block 1051 and information transfer module 1052 do not send information or regularly send security information to server 11 or mobile device
12。
In one embodiment, information transfer module 1052 can for GPRS (General Packet Radio Service,
General Packet Radio Service) module, WIFI module, bluetooth module or other components that can be transmitted information.Power supply unit 103
For to processing unit 105 and the power supply of other units, power supply unit 103 to include battery.
Referring to Fig. 2, Fig. 2 is the structural schematic diagram of 10 1 embodiment of door status sensor device of the present invention.
As shown in Fig. 2, in the present embodiment, Flexible element 102 is elastic slice, magnet unit 104 is permanent magnet, induction
Unit 101 is tongue tube.Door status sensor device 10 further includes shell, can accommodate Flexible element 102, magnet unit 104, induction
Unit 101, power supply unit 103 and processing unit.Shell includes first shell 210 and second shell 220, and processing unit 105 is set
It is placed in the space that first shell 210 and second shell 220 are surrounded.Second shell 220 has at one end with opening, Flexible element
102 one end for being provided with magnet unit 104 are penetrated by the opening in the encirclement space of first shell 210 and second shell 220.
Magnet unit 104 and sensing unit 101 be opposite, neighbouring setting.The folding shape elastic slice of Flexible element 102 is at an angle, in this implementation
In mode, the angle is at an acute angle.Flexible element 102 is in nature open configuration when not by external force.
Referring to Fig. 3, Fig. 3 is the structural representation of one embodiment when door status sensor device 10 receives external force in Fig. 2
Figure.
