Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Door lock detection circuitry embodiment:
referring to fig. 1, a schematic structural diagram of a door lock detection circuit provided by an embodiment of the present invention is shown in the figure. As shown in fig. 1, the door lock detection circuit includes: signal detection circuit 1, integrated circuit 2 and alarm device 3. Wherein, be provided with tapered end, hasp and power 4 on the signal detection circuitry 1, the one end of power 4 is connected with the tapered end through first connecting harness 5, and the other end of power 4 is connected with the hasp through second connecting harness 6. In this embodiment, the power source 5 may be a dc power source with a voltage value of 5V, for example, a battery with a voltage value of 5V, a positive terminal of the battery is connected to the lock via the first connection harness 5, and a negative terminal of the battery is connected to the lock via the second connection harness 6. Of course, the power supply 5 may be another type of dc power supply or ac power supply, which is not limited in this embodiment. The integrated circuit 2 may have another power supply inside.
Specifically, as shown in fig. 4, a metal contact may be disposed at the end face a of the latch 8, and when the lock head 9 is inserted into the latch 8, that is, when the lock head 9 and the latch are connected, the end face B of the lock head 9 may contact with the metal contact at the end face a of the latch 8, which is equivalent to placing the first switch 7 in the closed state in fig. 1, and accordingly, the whole signal detection circuit 1 will be in the closed power-on state. Preferably, the shape of the lock 9 is matched with the shape of the latch 8, so that when the lock 9 is inserted into the latch 8, the lock and the latch can be reliably connected to prevent the whole signal detection circuit 1 from being in an open state due to poor contact.
In the present embodiment, the first signal detection terminal 21 of the integrated circuit 2 is connected to the first connection harness 5 or the second connection harness 6. The first control signal output 22 of the integrated circuit 2 is connected to one end of the alarm device 3, and the other end of the alarm device 3 is connected to the first connecting wire harness 5 or the second connecting wire harness 6. Specifically, as shown in fig. 1, the first signal detecting terminal 21 of the integrated circuit 2 may be connected to the first connection harness 5, the first control signal output terminal 22 of the integrated circuit 2 may be connected to the upper end of the alarm device 3, and the lower end of the alarm device 3 may be connected to the first connection harness 5. When the disconnection time of the lock head and the lock catch exceeds a preset disconnection time threshold value, the integrated circuit 2 sends out a first signal to trigger the alarm device 3, so that the alarm device 3 gives an alarm. The disconnection duration threshold may be determined after statistics is performed on the door opening and closing time of a conventional city family, and is generally between 10s and 60s, for example, 20s, 30s, 40s, and the like. In particular, the alarm device 3 may have a timer therein. When the integrated circuit 2 detects that the lock head and the lock catch are in a disconnection state at a certain moment, the timer starts timing, when the timing duration of the timer reaches a disconnection duration threshold value, the timer stops timing or sends a signal to the alarm device 3, and at the moment, the integrated circuit 2 sends a first signal to trigger the alarm device 3 so that the alarm device 3 gives an alarm.
In specific implementation, the alarm device 3 may be a sound tube, a buzzer or a third indicator light, and if the alarm device is a sound tube, a prompt voice may be stored in the sound tube in advance. For the door lock detection circuit in fig. 1, when the lock head and the lock catch are in a connected state, that is, when the first switch 7 is in a closed state, the whole signal detection circuit 1 will be in a closed power-on state, the integrated circuit 2 can detect that current exists in the signal detection circuit 1, and the integrated circuit 2 does not output a control command; when the lock head and the lock catch are in an off state, namely, the first switch 7 is in an off state, the whole signal detection circuit 1 is in an off state, the integrated circuit 2 detects that no current exists in the signal detection circuit 1, when the time length for which the integrated circuit 2 detects that no current exists in the signal detection circuit 1 is less than or equal to an off time length threshold value, the door is in a normal open state, the integrated circuit 2 does not output a control instruction, and when the time length for which the integrated circuit 2 detects that no current exists in the signal detection circuit 1 is greater than the off time length threshold value, the door is in an abnormal open state, so the integrated circuit 2 can control the alarm device 3 to send out an alarm signal, namely, the buzzer sends out an alarm sound, the sound tube plays prompt voice or sends out more obvious light through the third indicator lamp, and therefore, a user can send out the alarm sound according to the buzzer, The door can be known not to be closed well by the prompt voice played by the sound tube or the light emitted by the third indicator light.
As shown in fig. 2 and 3, the positive terminal of the power source 4 may be connected to one end of the first resistor 10 (the right end of the first resistor 10 shown in fig. 2) through the second connection harness 6, and the negative terminal of the power source 4 may be connected to the other end of the first resistor 10 (the left end of the first resistor 10 shown in fig. 2) through the first connection harness 5. Thus, for the door lock detection circuit in fig. 2 and 3, when the lock head and the lock catch are in a connected state, which is equivalent to that the first switch 7 is in a closed state, the line where the first switch 7 is located short-circuits the line where the first resistor 10 is located, and the current only flows through the first switch 7, but not through the first resistor 10; when the lock and the latch are in an off state, which is equivalent to the first switch 7 being in an off state, the current only flows through the first resistor 10, but not through the first switch 7. It is obvious that the amount of signal detected by the integrated circuit 2, i.e. the current over the entire signal detection circuit 1, is different in the two cases described above, the latter case being lower than the former case. When the integrated circuit 2 is used specifically, timing can be started from the moment when the current in the signal detection circuit 1 suddenly decreases, when the duration of the condition that the current value is small reaches the disconnection duration threshold value, that is, the door is in an abnormal opening state, at this time, the integrated circuit 2 can control the alarm device 3 to send out an alarm signal to prompt that the home door is not closed well.
As shown in fig. 1 to 3, the signal detection circuit 1 may further include a second resistor 11, a second switch 12, and a fuse 13. The second resistor 11 may perform a voltage division function, the second switch 12 may control on/off of the entire signal detection circuit 1, and the fuse 13 may be blown when a current on the signal detection circuit 1 is too large, so as to protect elements on the entire signal detection circuit 1.
In this embodiment, when the time of disconnection between the lock head and the lock catch of the door lock exceeds the preset time threshold value of disconnection, the alarm device 3 sends an alarm signal, for example, an alarm sound or a voice prompt is output to warn the householder, so that the householder can timely detect that the door is not closed well and immediately close the door, thereby better avoiding the potential safety hazard caused by the unclosed door, and further reliably ensuring the safety of living in the room.
In the above embodiment, the alarm device 3 may further include an intercom module. This lock detection circuitry still includes: a three-phase switch 14. The common end of the three-phase switch 14 is connected to one end of the alarm device 3 (the upper end of the alarm device 3 shown in fig. 1 and 2), the first end of the three-phase switch 14 is connected to the second connection harness 6 or the first connection harness 5 through the third connection harness 15, and the second end of the three-phase switch 14 is connected to the second connection harness 6 or the first connection harness 5 through the third resistor 16.
Specifically, as shown in fig. 1 to 3, when the other end of the alarm device 3 is connected to the first connection harness 5, the first end of the three-phase switch 14 is connected to the second connection harness 6 through the third connection harness 15, and the second end of the three-phase switch 14 is connected to the second connection harness 6 through the third resistor 16; when the other end of the alarm device 3 is connected to the second connection harness 6, the first end of the three-phase switch 14 is connected to the first connection harness 5 through the third connection harness 15, and the second end of the three-phase switch 14 is connected to the first connection harness 5 through the third resistor 16.
It can be seen that, under the condition that the alarm device 3 does not send out the alarm signal, the talkback module in the alarm device 3 can be started, even if the personnel on both sides of the door provided with the alarm device 3 talkback, and because the first end of the three-phase switch 14 is connected with the third connecting wire harness 15, the third connecting wire harness 15 can short-circuit the third resistor 16, at this time, the current passing through the alarm device 3 will be larger, so the talkback effect of the alarm device 3 will be better. In the above embodiment, the door lock detection circuit may further include: communication means (not shown in the figure). Wherein the communication means are arranged within the integrated circuit 2 or the communication means are connected to a second control signal output of the integrated circuit 2. When the disconnection time of the lock head and the lock catch exceeds the disconnection time threshold, the integrated circuit 2 sends notification information to the communication device, so that the communication device sends an alarm signal to the remote mobile terminal. In specific implementation, the communication device may be a SIM card, a card slot for accommodating the SIM card is provided in the integrated circuit 2, and the remote mobile terminal may be a mobile phone. Therefore, when the integrated circuit 2 detects that the disconnection time of the lock head and the lock catch exceeds the disconnection time threshold, the integrated circuit 2 can send an alarm signal to the mobile phone of the householder through the SIM card, for example, send a short message or an e-mail to the mobile phone of the householder, so that the householder can timely know that the door is not closed according to the received short message or the received e-mail and then inform neighbors or property personnel to help to close the door, thereby better ensuring the safety of living in rooms.
It can be seen that the above embodiments can all ensure the safety of living in the room well, but in some cases, the householder may want the door to be opened for a long time but the alarm device 3 does not give an alarm signal, for example, some householders may want to open the door, and then change shoes outside the door and enter the room, to list two ways that can achieve the above effects.
In one approach, as shown in fig. 2, the integrated circuit 2 may have a timer therein, i.e., the timer is integrated within the integrated circuit 2. This lock detection circuitry still includes: a delay button 17. Wherein the delay button 17 is connected to the second signal detection terminal 23 of the integrated circuit 2. In this way, the integrated circuit 2 can start the timer and update the off duration threshold each time the integrated circuit 2 detects that the delay button 17 is pressed, the off duration threshold after each update is greater than the off duration threshold before the update, and the integrated circuit 2 sends out the first signal to trigger the alarm device 3 when detecting that the timer is timed out. The difference between the disconnection duration threshold after each update and the disconnection duration threshold before the update may be a constant, and the constant may be 60 s. Specifically, assuming that the off-period threshold is 30s in the initial state, the off-period threshold becomes 90s after the delay button 17 is pressed once, the off-period threshold becomes 150s after the delay button 17 is pressed twice, and so on. It can be seen that the time when the alarm device 3 sends the alarm signal can be delayed by pressing the delay button 17 in the embodiment, and the operation is simpler.
It should be noted that if the lock and the lock catch are normally closed before the timer counts, the timer will not count again. Next, if the integrated circuit 2 detects that the lock and the latch are in the off state again, the timer will resume the next round of timing operation.
In another mode, as shown in fig. 3, the door lock detection circuit may further include: a delay button 17 and a time switch 18. Wherein the delay button 17 is connected to a second signal detection terminal 23 of the integrated circuit 2, one end of the timer switch 18 (the left end of the timer switch 18 shown in fig. 3) is connected to the first connection harness 5 or the second connection harness 6, and the other end of the timer switch 18 (the right end of the timer switch 18 shown in fig. 3) is connected to a third signal detection terminal 24 of the integrated circuit 2. In this way, each time the integrated circuit 2 detects that the delay button 17 is pressed, the integrated circuit 2 may send a timing start command to the time switch 18 and update the off duration threshold, the off duration threshold after each update being greater than the off duration threshold before the update, and the integrated circuit 2 may send a first signal to trigger the alarm device 3 when detecting that the timing duration of the time switch 18 reaches the off duration threshold after the update. The difference between the disconnection duration threshold after each update and the disconnection duration threshold before the update may be a constant, and the constant may be 60 s. Specifically, assuming that the off-period threshold is 30s in the initial state, the off-period threshold becomes 90s after the delay button 17 is pressed once, the off-period threshold becomes 150s after the delay button 17 is pressed twice, and so on.
It can be seen that, in this embodiment, the time when the alarm device 3 sends the alarm signal can be delayed by pressing the delay button 17, and the operation is simpler.
It should be noted that, as shown in fig. 2 and 3, when the householder needs to open the door for a long time, such as cleaning, the householder can directly switch off the second switch 12 in addition to pressing the delay button 17, and at this time, no current is flowing in the signal detection circuit 1, and the alarm device 3 will not send out an alarm signal. When the door is not required to be opened any more, the second switch 12 can be closed, so that the alarm device 12 can detect the state of the door and send out an alarm signal when the door is in an abnormal opening state.
With continued reference to fig. 1-3, in the above embodiment, the door lock detection circuit may further include: a first indicator light 19. In particular, the first indicator light 19 may be a light emitting diode. One end of the first indicator lamp 19 (the left end of the first indicator lamp 19 shown in fig. 1 to 3) is connected to the third control signal output terminal 25 of the integrated circuit 2, and the second end of the first indicator lamp 19 (the right end of the first indicator lamp 19 shown in fig. 1 to 3) is grounded. When the integrated circuit 2 detects that the lock head and the lock catch are in the off state, a second signal is sent out through the third control signal output end 25, so that the first indicator lamp 19 is lightened.
Preferably, a fourth resistor 20 may be disposed on a connection harness between one end of the first indicator light 19 and the third control signal output terminal 25 of the integrated circuit 2 to prevent the first indicator light 19 from being burned out due to an excessive current flowing through the first indicator light 19.
It can be seen that the arrangement of the first indicator light 19 enables the householder to know whether the door is not closed or not conveniently and quickly, and does not need to specially go to the door side to confirm whether the lock head is reliably connected with the lock head or not.
In the above embodiment, the door lock detection circuit may further include: a second indicator light (not shown). In particular, the second indicator light may be a light emitting diode. One end of the second indicator light is connected with the fourth control signal output end of the integrated circuit 2, and the second end of the second indicator light is grounded. When detecting that the lock head and the lock catch are in a connection state, the integrated circuit sends a third signal through the fourth control signal output end so that the second indicator light is turned on, and the first indicator light 19 and the second indicator light send out light with different colors when turned on.
Preferably, a fifth resistor may be disposed on the connection harness between one end of the second indicator light and the fourth control signal output end of the integrated circuit 2, so as to avoid the second indicator light from being burned out due to an excessive current flowing through the second indicator light.
It can be seen that the arrangement of the second indicator light can enable a householder to conveniently and quickly know whether the door is closed or not, and the householder does not need to specially go to the door to confirm whether the lock head is reliably connected with the lock head or not.
It should be noted that, the door lock detection circuit may be provided with two leds capable of emitting different colors, or with only one three-pin led capable of emitting different colors, and then the integrated circuit 2 controls the three-pin led to emit one color when the lock head is connected to the lock catch, and controls the three-pin led to emit another color when the lock head is disconnected from the lock catch, so that the door lock detection circuit can also make the householder conveniently and quickly know the state of the door.
In the above embodiment, the alarm device 3 may be provided on a panel of the door on which the door lock detection circuit is mounted. In specific implementation, the alarm device may also be disposed at other positions on the door, which may be determined according to actual conditions, and this embodiment is not limited to this.
To sum up, this embodiment can make the householder in time perceive the problem that the door is not closed well, so the householder can close the door well immediately to better avoid because the door does not close the potential safety hazard that exists, and then guaranteed the security of living room life reliably.
