Specific embodiment

Below in conjunction with attached drawing, specific embodiment of the present utility model is described in further detail, so that the utility model skill Art scheme is more readily understood and grasps.

Referring to Fig.1, Fig. 2 present embodiments provides a kind of smart home Anti-theft detection device, including toroidal shell 31, and Control module 53, wireless communication module 54, detection module 51 and the power module 52 being installed in toroidal shell 31.Control module 53, wireless communication module 54 is integrated on pcb board 4.Toroidal shell 31 is installed on door 1, and lock body 2 is enclosed in inside.

In the present embodiment, detection module 51 includes infrared inductor, is installed on the inner sidewall of toroidal shell 31；Separately Outside, other sensors, such as photoelectric sensor etc. can also be used in detection module 51.Electricity is provided on the inner sidewall of toroidal shell 31 Pond slot 32, power module 52 are lithium battery.

Control module 53 includes edge sense circuit, timing circuit, logic circuit and main control chip；Main control chip is using single Piece machine.

Edge sense circuit is electrically connected with the output end of infrared inductor, and the output signal for detecting infrared inductor is No there are rising edges, failing edge, and export corresponding rising edge detection signal V1, failing edge detection signal V2.

Timing circuit is electrically connected with edge sense circuit, is timed for detecting signal according to rising edge, and in timing After export corresponding timing signal Vd；

Logic circuit includes not circuit N1 and AND gate circuit N2, and the input terminal of not circuit N1 is electrically connected to Edge check Circuit is to receive failing edge detection signal V2；One of input terminal of AND gate circuit N2 be electrically connected to not circuit N1 from defeated Outlet, another input terminal are electrically connected to the output end of timing circuit Vd, and output end is electrically connected to main control chip.Wireless telecommunications mould Block 54 is electrically connected with main control chip；The logical signal Vk that main control chip is exported according to logic circuit is to control wireless communication module 54 Issue alarm command.

Therefore, the working principle of the present embodiment is: when key is inserted into lock body 2, infrared inductor can be triggered, it is infrared The output signal of inductor is got higher by low, and then the rising edge of edge sense circuit output high level detects signal, and triggers and determine When circuit.Timing circuit be triggered after start timing, during timing, if key takes out out of lock body 2, infrared inductor it is defeated Signal is lower by height out, and then the failing edge of edge sense circuit output high level detects signal, in this way, AND gate circuit N2 is exported Logical signal Vk remain low level；Otherwise, after timing, logical signal Vk is high level, and main control chip receives After the logical signal Vk of high level, then controls wireless communication module 54 and issue alarm command.User can utilize the alarm evidence of pairing This device receives instruction indoors.In addition, main control chip can also configure remote communication module, with to the mobile phone of user or other tools There is the mobile terminal of network function to be communicated, realizes long-range warning note.
