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, a kind of smart home anti-theft alarm system, including detection device 3 and alarm dress are present embodiments provided Set 6.Detection device 3 is installed on outside door 1, and warning device 6 is installed in door 1.

Referring to Fig. 2, Fig. 3, detection device 3 includes toroidal shell 31, and be installed in toroidal shell 31 control module 53, Wireless transmitter module 54, detection module 51 and the first power module 52.Control module 53, wireless transmitter module 54 are integrated in On one 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, the first 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 transmission 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 transmitter module 54 Issue alarm command.

Referring to Fig. 4, Fig. 5, Fig. 6, warning device 6 includes shell 61, and be installed in shell 61 wireless receiving module 83, Alarm module and second power supply module 82；Wireless receiving module 83, alarm module are integrated on the second pcb board 7.
