Anti-theft door and window automatic detection method based on network

[0012] The specific working steps of the present invention are as follows figure 1 Shown. The automatic detection module detects the closed state of the target door and window. Once the target state changes, the automatic detection module generates a meaningful message, which can be stored in the memory of the detection module and sent to the network transmission connected to the Internet Module, upload to the designated website. When users need to view the status change records of the target doors and windows, they can log in to the website to view them.

[0013] In a specific implementation, when the status of the target door and window changes, the network transmission module can upload the message to the website while using technical means to directly notify the customer of the message. This technical method is declared in Chinese patent ZL201120417607.1.

[0014] The automatic detection module can be connected to the target door and window in a contact or non-contact manner.

[0015] figure 2 The picture A depicts a contact connection implementation, where 3 is a metal contact piece fixed on the target door and window; 1 and 2 are two wires connected to the automatic detection module. When the target door and window are closed, the wires 1 and 2 are connected by the metal contact piece 3 to form an electrical path. The detection module can determine that the target door and window are closed; when the target door and window are opened, the wires 1 and 2 form an electrical disconnection, and the detection module It can be determined that the target door and window are open.

[0016] figure 2 The B picture depicts a non-contact connection implementation, where 2 is a cover fixed on the target door and window; 1 is an optocoupler connected to the automatic detection module. When the target door and window are closed, the cover 2 separates the optocoupler, and the detection module can determine that the target door and window are closed; when the target door and window is open, the photocoupler is turned on, and the detection module can determine that the target door and window is open.

[0017] In a specific implementation, the detection module can use timed query mode and interrupt mode to detect doors and windows on the software. image 3 Figure A is an implementation plan for detecting target doors and windows by query; image 3 Figure B is an implementation plan for detecting target doors and windows by interruption.

[0018] In a specific embodiment, one port of the detection module corresponds to a target door or window. In this case, one detection module can detect a target door or window.

[0019] In a specific embodiment, one port of the detection module corresponds to one target door or window. In this case, multiple ports of one detection module can correspondingly detect multiple target doors or windows.

[0020] In the present invention, the automatic detection module refers to an electronic component with program operation capability and its supporting circuit. Such as Figure 4 In a specific embodiment shown, the CPU can be a 51-series single-chip microcomputer C8051F020, various other types of microprocessors, DSPs, processors, and replaceable semiconductor devices with computing capabilities; the extended memory can be AT24C1024 or It is other types of volatile and non-volatile data storage; the power supply and program monitoring circuit adopts MAX813L chip to switch between power supply and backup battery and program operation monitoring, and other types of power monitoring chips can also be used to achieve this function; Door and window motion detection mechanism can be used but not limited to figure 2 Given methods (such as ultrasonic detection; infrared detection; brightness detection; distance detection; resistance detection, etc.), the mechanism is connected to one or more I/O ports of the CPU, and the I/O ports can be judged by the relevant programs in the CPU Status to obtain the door and window switch status; the communication circuit can adopt serial port, parallel port, USB mode, infrared, I 2 C and other methods and figure 1 The network transmission module in the communication; other circuits include the supporting circuits of the above-mentioned circuits.

[0021] In a specific embodiment, figure 1 The network transmission module in the RTL8019AS chip is connected to the Internet. In other solutions, the module can also use Internet communication modules such as WiFi, Modem, GPRS, 3G, etc. to achieve the above functions.

[0022] In a specific embodiment, figure 1 The network transmission module in can add a mobile phone short message module to realize the target door lock status message is sent directly to the customer's mobile phone.

[0023] In a specific embodiment, Figure 5 The function diagram of the website is given. The website obtained from this figure can realize the information inquiry and management of the status of the target doors and windows. The website can have a computer version and a mobile version. For smart phone users, you can develop the mobile phone application of this website for the convenience of customers.

[0024] In the specific implementation process of the present invention, the target door and window result message generated by the automatic detection module may contain specific information: for example, current time, current action port number, current status of doors and windows, and agreed character strings. The information is encrypted during transmission; on the website side, the received upload information is verified and stored in the database; all content in the database related to user privacy is encrypted.
