The utility model is by detecting that external door has personnel to walk out, while whether testing staff carries outer door key with it,
If be not detected, suggestion voice can be issued in time, thus effectively prevent personnel due to forgeing outer door key caused by bother.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model house door key reminder.
Fig. 2 is the working principle diagram of the utility model house door key reminder.
Specific embodiment
The embodiments of the present invention that the following is further explained with reference to the attached drawings.
Referring to Figure 1 and shown in Fig. 2, a kind of house door key reminder, including key demarcate label 1, personnel direction
Inductor 2, integrated control circuit 3, key radio frequency induction device 4 and voice reminder module 5, the key calibration label 1 are pasted
On outer door key, personnel's direction inductor device 2 is connected to integrated control circuit 3, and the integrated control circuit 3 is distinguished
It is connected with key radio frequency induction device 4 and voice reminder module 5, the key radio frequency induction device 4 is read by radiofrequency signal
Key demarcates the electronic tag coding of label 1.
Preferably, personnel's direction inductor device 2 uses two infrared thermal releasing electric induction for being mutually 120 degree of angles
Head, the infrared thermal release electric inductive head use RDA226 digital thermal and release electrical chip.In the infrared thermal release electric inductive head
Portion is provided with processing circuit, and high level logic signal can be exported after sensing human infrared signal.
Preferably, microcontroller chip SH89F52 is provided with inside the integrated control circuit 3 as logic controller.
Preferably, the key radio frequency induction device 4 uses electronic label read-write chip THM3070, the key
Radio frequency induction device 4 is integrated with annular high frequency read-write antenna.
Preferably, the voice reminder module 5 uses voice and plays chip QGPH520, the voice reminder mould
The external PWM audio output loudspeaker of block 5, the voice reminder module 5 are controlled by I/O interface and are triggered.
Two infrared thermal release electric inductive heads are used inside personnel's direction inductor device 2, a direction is indoor, and one
It is directed toward outdoor, after the infrared thermal release electric inductive head senses human infrared signal, high level logic signal can be exported, it is comprehensive
Control circuit 3 is connected respectively to two infrared thermal release electric inductive heads by two I/O interfaces, when integrated control circuit 3 is connected to room
After the I/O interface of interior infrared thermal release electric inductive head receives high level signal, in the timing of inner setting, comprehensively control
The I/O interface that circuit 3 is connected to outdoor infrared pyroelectric sensing head receives high level signal again, and representative currently has personnel to walk out
External door, then integrated control circuit 3 can be controlled key radio frequency induction device 4 and be detected in radio-frequency region and whether there is by SPI interface
Key demarcates the electronic tag coding of label 1, if key radio frequency induction device 4 reads the electronic tag of key calibration label 1
Coding, integrated control circuit 3 collect the electronic tag by SPI interface and encode, and represent the personnel's carrying for currently walking out external door
The outer door key of key calibration label 1 is pasted, then integrated control circuit 3 does not do any operation；And if comprehensively control is electric
Road 3 can't detect the electronic tag coding that the key of external door on the key demarcates label 1 by key radio frequency induction device 4, and representative is worked as
Before walk out the personnel of external door to carry outer door key, then integrated control circuit 3, which is understood, trigger voice reminder by I/O interface immediately
5 broadcasting personnel of module do not carry the suggestion voice of outer door key, to effectively personnel be reminded to find outer door key immediately, avoid not
It carries outer door key and is locked out, cause certain trouble.
The human infrared signal that the integrated control circuit 3 is incuded by two infrared thermal release electric inductive heads of detection, just
It can effectively judge that personnel walk to go out or walk to enter, if integrated control circuit 3 first detects outdoor infrared pyroelectricity
The high level signal of inductive head detects the high level signal of indoor infrared pyroelectric sensing head again, and the personnel of representative are walked from outdoor
Enter interior, or if integrated control circuit 3 is detected simultaneously by the high level signal of two infrared thermal release electric inductive heads, representative is worked as
Preceding personnel do not go out, but stand near door, and at this time in order to avoid accidentally responding, the integrated control circuit 3 is not appointed
What control operation.
The key radio frequency induction device 4 stated can be such that radio frequency reading/writing distance controls by integrated annular high frequency read-write antenna
Within the scope of 1.5 meters, therefore the detection range of radiofrequency signal can be made effectively to cover the active component of personnel.
The utility model is by detecting that external door has personnel to walk out, while whether testing staff carries outer door key with it,
If be not detected, suggestion voice can be issued in time, thus effectively prevent personnel due to forgeing outer door key caused by bother.
