Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1, the utility model discloses a prevent forgetting to pull out the key and prevent forgetting to take the multi-functional security protection device of key, it includes single chip module 1, voice module 2, be used for detecting whether the door opens the switch door detection module 3 of opening and close and be used for detecting whether the indoor side handle of door opens the door and rotates door handle detection module 4; the single chip microcomputer module 1 is electrically connected with the voice module 2, the door opening and closing detection module 3 and the door handle detection module 4.

When the utility model is used, the single chip microcomputer module 1 respectively detects whether the door is opened and whether the indoor side handle of the door is rotated by opening the door through the door opening and closing detection module 3 and the door handle detection module 4; when the door is opened and the handle at the indoor side of the door rotates, the single chip microcomputer module 1 judges that the door is opened from the indoor, and then the single chip microcomputer module 1 plays sound through the voice module 2 to remind people to go out and remember to take a key; and when the door was opened and the indoor side handle of door did not rotate, single chip module 1 judged that the door was opened from the open air, and single chip module 1 plays sound through voice module 2 this moment to remind people to enter and remember to pull out the key, thereby avoid people to unblank and forget to pull out the key when entering.

As shown in fig. 1, the voice module 2 includes a voice playing module 21 electrically connected to the single chip microcomputer module 1, and a speaker 22 electrically connected to the voice playing module 21, where the model of the voice playing module 21 may be DY-SV 5W.

As shown in fig. 1, the switch door detection module 3 includes a first resistor R1 and a micro switch S1, a first end of the micro switch S1 is electrically connected to the power supply VCC through the first resistor R1, and a second end of the micro switch S1 is grounded; one input end of the singlechip module 1 is electrically connected with the first end of the microswitch S1. The principle of the door opening and closing detection module 3 is as follows: when the door is closed, the door presses the microswitch S1, so that the input end of the singlechip module 1 connected with the microswitch S1 receives a low level signal; when the door is opened, the micro switch S1 is not pressed by the door any more, so that the input end of the singlechip module 1 connected with the micro switch S1 receives a high-level signal.

As shown in fig. 1, the door handle detection module 4 includes a second resistor R2 and a mercury switch S2, a first end of the mercury switch S2 is electrically connected to the power supply VCC through the second resistor R2, and a second end of the mercury switch S2 is grounded; one input end of the singlechip module 1 is electrically connected with the first end of the mercury switch S2; the principle of the door handle detection module 4 is as follows: the mercury switch S2 is fixed on the indoor side handle of the door, when the indoor side handle of the door is opened and rotated, the mercury switch S2 rotates along with the indoor side handle to change the conducting state of the mercury switch S2, so that the input end of the singlechip module 1 connected with the mercury switch S2 receives a level signal and changes; the utility model discloses can set for: when the indoor handle of the door is opened and rotated, the mercury switch S2 is switched from the off state to the on state, and then the signal received by the input end of the singlechip module 1 connected with the mercury switch S2 is switched from a high level signal to a low level signal; the utility model discloses can also set for: when the indoor handle of the door is opened, the mercury switch S2 is switched from the on state to the off state, and then the signal received by the input end of the singlechip module 1 connected with the mercury switch S2 is switched from the low level signal to the high level signal.

As shown in the figure 1, the utility model discloses still can include radio frequency card reader module 5 and GSM module 6, single chip module 1 is connected with radio frequency card reader module 5 and GSM module 6 electricity, and radio frequency card reader module 5 can be RC522 radio frequency module, and GSM module 6 can be the SIM900 module. The utility model discloses when single chip module 1 judges that the door is opened from the open air, the utility model discloses when reminding people to enter the door through 2 broadcast sounds of voice module and remember to pull out the key, the utility model discloses still get into the verification flow of punching the card. In the card swiping verification process, the single chip microcomputer module 1 firstly monitors whether the radio frequency card reader module 5 identifies a radio frequency card meeting the preset verification requirement within the preset time, and if the single chip microcomputer module 1 monitors that the radio frequency card reader module 5 identifies the radio frequency card meeting the preset verification requirement within the preset time, the single chip microcomputer module 1 judges that the verification is successful; if the single chip microcomputer module 1 monitors that the radio frequency card reader module 5 does not identify the radio frequency card meeting the preset verification requirement within the preset time, the single chip microcomputer module 1 plays a sound through the voice module 2 to remind people to carry out card swiping verification and monitors whether the radio frequency card reader module 5 identifies the radio frequency card meeting the preset verification requirement within the preset time again; if the single chip microcomputer module 1 monitors that the radio frequency card reader module 5 or the radio frequency card meeting the preset verification requirement is not identified in the preset time, the single chip microcomputer module 1 judges that the verification fails, otherwise, the single chip microcomputer module 1 judges that the verification succeeds. After the single chip microcomputer module 1 judges that the verification is successful, the single chip microcomputer module 1 judges that the door is normally opened, and the single chip microcomputer module 1 can play welcome voice through the voice module 2; after the single chip microcomputer module 1 judges that the verification fails, the single chip microcomputer module 1 determines that the illegal break-in condition exists, the single chip microcomputer module 1 sends an alarm short message to the resident through the GSM module 6 to give an alarm, and meanwhile, the single chip microcomputer module 1 can play an alarm voice through the voice module 2, wherein the alarm voice can be 'you are not the resident of the house, please exit the house as soon as possible, and i have informed the resident of the house'.

In conclusion, the utility model can remind people to go out and remember to take the key and go in and remember to pull out the key, thereby avoiding the inconvenience caused by forgetting to take the key and the potential safety hazard caused by forgetting to pull out the key, and effectively improving the convenience and the safety of family life of people; and the utility model discloses be from outdoor when opening at the door, the utility model discloses a whether there is the condition of illegal intrusion in can be confirmed to singlechip module 1 and radio frequency card reader module 5, if there is the condition of illegal intrusion, then the utility model discloses can send the warning SMS for the resident family through GSM module 6 to further improve the security of people's family life.
