In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
The first embodiment is as follows:
fig. 2 shows an implementation flowchart of a method for detecting a door state according to an embodiment of the present application, which is detailed as follows:
s21, a first detection unit detects whether a lock tongue is knocked out, wherein the lock tongue comprises a first lock tongue and a second lock tongue;
the embodiment that this application provided is after the door is closed, whether all there is the spring bolt to beat by first detecting element detection installation door lock on the door, wherein, the spring bolt includes first spring bolt and second spring bolt. The first lock bolt can be a big square bolt, and the second lock bolt can be a reverse bolt.
Optionally, the first detecting unit detects whether there is a lock tongue to be struck, including:
the first detection unit includes at least one contact switch;
the contact switch is used for detecting whether the lock tongue is knocked out, and the main control unit judges whether the lock tongue is knocked out according to the on-off state of the contact switch;
and if the contact switch is detected to be in a non-closed state, the main control unit judges that the lock tongue is opened.
In this step, as shown in fig. 3, the first detection unit is provided with a contact switch 31, and the contact switch 31 is disposed at an end where the latch 32 cannot be operated, that is, the contact switch 31 is disposed at an end that remains in the lock even if the latch 32 is operated. The contact switch 31 can be in an off state when the bolt 32 is opened, and the contact switch can be closed when the bolt 32 is retracted, so that the main control unit can determine that the bolt is opened if the contact switch is detected to be in a non-closed state.
Optionally, the first detecting unit detects whether there is a lock tongue to be struck, and further includes:
the first detection unit comprises a magnet and a sensor;
the main control unit detects a level value output by a sensor which is arranged in the movement direction of the lock tongue and is far away from one side of the lock tongue, wherein the sensor is arranged at one side of the lock tongue;
and if the level value exceeds a preset level value, the main control unit judges that the lock tongue is turned out.
In this step, the first detecting unit is provided with a sensor 41, for example, a Tunnel Magnetic Resistance (TMR) sensor 41 or other sensor with magnetic induction detecting function, a magnet 42 (as shown in fig. 4) is provided on one end of the corresponding lock tongue still located in the lock body when the lock tongue is driven out, when the magnet 42 is close to the sensor 41, the sensor output 41 outputs a lower level value, and when the magnet 42 is far away from the sensor 41, the sensor outputs a higher level value; therefore, a predetermined level value is set, the level value outputted from the sensor 41 is checked, and if the level value outputted from the sensor 41 is greater than the predetermined level value, it is judged that the latch is tripped when the magnet 42 is away from the sensor 41 due to the trip of the latch.
Step S22, if the first detection unit detects that the first lock tongue is knocked out, the main control unit judges whether the door handle is locked indoors or outdoors according to the state of the door handle detected by the second detection unit and outputs a judgment result;
in the embodiment provided by the application, when the first detection unit detects that the first lock tongue is knocked out, the second detection unit is instructed to detect the state of the door handle, and the detection data is sent to the main control unit, so that the main control unit judges whether the door is locked outside the door or inside the door according to the detection data of the second detection unit. Alternatively, the judgment result is directly displayed on a display screen on the door. Or, optionally, the judgment result is output to a cloud server, and the judgment result is pushed to a corresponding user by the cloud server.
Optionally, the main control unit determines whether to lock the door handle indoors or outdoors according to the state of the door handle detected by the second detection unit, and includes:
the second detecting unit detects whether a door handle is rotatable, the door handle including an inner door handle and an outer door handle;
if the second detection unit detects that the inner door handle is in a rotatable state, the main control unit judges that the interior of the house is locked;
and if the second detection unit detects that the outer door handle is in a rotatable state, the main control unit judges that the outside is locked.
In this step, the second detection unit detects the state of the door handle, where the door handle includes an outer door handle and an inner door handle. Specifically, the second detecting unit detects the turning of the door handle, and in general, when the door is a rectangular or square door, assuming that the door handle is in an initial state when being in a horizontal state with respect to the upper door frame or the lower door frame, and when the door handle is at a certain angle with respect to the initial state, the door handle is considered to be in a turnable state; the size of the certain angle can be set by a user according to the door lock, and is not limited herein.
At this time, the second detection unit detects the rotatable angles of the inner door handle and the outer door handle with respect to the initial state, respectively, and if it is detected that the rotatable angle of the inner door handle with respect to the initial state is larger than the first angle set by the user, it is determined that the inner door handle is in the rotatable state, and it is determined that the indoor locking is performed.
Similarly, if the rotatable angle of the outer door handle relative to the initial state is detected to be larger than a second angle set by a user, the outer door handle is considered to be in a rotatable state, and then the outdoor locking is judged; the first angle and the second angle may be the same or different in size, and may be set by a user.
Optionally, the second detecting unit detects whether the door handle is in a rotatable state, including:
if a sensor is arranged in the intelligent door lock and a magnet is arranged in the door handle, the main control unit acquires the variation of the magnetic flux detected by the sensor or the detected polarity change condition of the magnet;
the main control unit judges whether the door handle is in a rotatable state according to the variation of the magnetic flux or the polarity variation of the magnet.
In this step, a magnet 51 is provided in the door handle, the magnet 51 is provided above one end of the door handle wrapped inside the door lock (as shown in fig. 5), a sensor 52, such as a TMR sensor, is provided above the magnet 51, and the sensor 52 is provided right above the center position of the magnet 51 in the length direction. Further, the sensor 52 may be provided on the PCB board.
Before that, a relationship between the amount of change in the magnetic flux received by the sensor 52 and the angle of rotation of the door handle with respect to the initial state is established, the change in the magnetic flux received by the sensor 52 is detected, and the angle of rotation of the door handle with respect to the initial state is determined. For example, in fig. 5, when the door handle is pressed down, the sensor 52 receives an increase in the magnetic flux of the N pole of the magnet, and when the door handle is lifted up, the TMR sensor 52 receives an increase in the magnetic flux of the S pole of the magnet.
Alternatively, in another embodiment provided herein, a magnet 61 is provided in the door handle, the magnet 61 is disposed above one end of the door handle that is wrapped inside the door lock (as shown in fig. 6), a sensor 62, which may be a TMR sensor, is disposed above the magnet 61, and a sensor 63, which may be a TMR sensor, is disposed at each end of the magnet 61. Further, the sensor 62 and the sensor 63 may be provided on a PCB board.
If the polarity of the magnet 61 detected by the door handle rotation sensor 62 or the sensor 63 is changed, for example, the polarity detected by the sensor 63 changes from S-pole to N-pole during the process of pressing down the door handle, and the polarity detected by the sensor 63 changes from N-pole to S-pole during the process of releasing the door handle, it can be considered that the door handle is pressed down. During the process of lifting the door handle, the sensor 62 detects that the N pole is changed into the S pole, and during the process of releasing the door handle, the polarity detected by the sensor 63 is changed from the S pole into the N pole, so that the handle can be considered to be lifted if the process is satisfied.
Further, since the change of the polarity detected by the sensor is caused by the change of the magnetic flux of the N pole or S pole of the magnet, the change angle of the door handle can be determined according to the change of the magnetic flux detected by the sensor, and the specific implementation method is as described above.
And S23, if the first detection unit detects that the second bolt is knocked out, the main control unit outputs indoor locking.
In the embodiment provided by the application, if the second bolt is detected to be knocked out, the main control unit can directly judge that the indoor lock is locked. The main control unit reports the judgment result to the cloud server so that the cloud server pushes the judgment result to the corresponding user.
In another embodiment provided by the present application, the method for detecting the door state further comprises
Step S20, the bolt further comprises a third bolt and an optical sensor, and accordingly when the first detection unit detects that the state of the third bolt of the intelligent door lock changes, the main control unit detects whether the optical sensor receives reflected light; if the reflected light is received, the door is judged to be correctly closed.
Before or after the door is determined to be locked indoors or locked outdoors, further detecting whether the door is correctly closed; at this time, the door lock installed on the door further includes a third locking tongue, which may be a dead bolt. A small hole is formed between the lock tongue of the door lock and the lock tongue and is arranged on the side, where the lock tongue of the intelligent door lock is opened, of the intelligent door lock, and the diameter of the small hole can be 1cm or other numerical values. The light sensor is arranged in the small hole, and the size of the small hole can ensure that the light sensor can receive light. The optical sensor is also connected with the main control unit to transmit detection data to the main control unit.
In this step, if the first detecting unit detects that the state of the latch bolt changes, a warning message that the door lock is opened is sent, and then whether a light sensor arranged in the small hole receives light is detected, and if the light sensor receives light, the door is correctly closed, and a warning message that the door is correctly closed is sent. The above step S20 may be executed before step S21 to determine whether the door is correctly closed, or after step S23 to determine whether the door is correctly closed and locked.
According to the embodiment of the application, the first detection unit detects whether the lock tongue is knocked out, if the first lock tongue is knocked out, the main control unit judges whether the door handle is locked indoors or outdoors according to the state of the door handle detected by the second detection unit, and then the judgment result is output; if the second bolt is detected to be knocked out, the main control unit judges whether the indoor lock or the outdoor lock is locked according to the state of the back locking knob detected by the second detection unit, and outputs a judgment result. In the process, the user can clearly know whether the lock is locked indoors or outdoors through detecting the lock tongue and the door handle.
