Fig. 1 is a schematic flow chart of a door locking method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step 100, i.e. signal determination step: determining whether the first target equipment receives a second near field communication signal, wherein the second near field communication signal is a signal generated after the second target equipment receives a first near field communication signal sent by the first target equipment; one of the cabinet body and the door body of the container is first target equipment, and the other one of the cabinet body and the door body of the container is second target equipment;
step 200, namely a door lock control step: and controlling the door lock state of the door body based on the determination result of the signal determination step.
With reference to fig. 5 and fig. 6, a door locking method in an embodiment of the present invention is described below by taking a first target device as a cabinet 100 and a second target device as a door 200 as an example, where the above-mentioned cabinet 100 generally refers to a cabinet with an NFC master device 310, and the above-mentioned door 200 generally refers to a door with an NFC slave device 320:
the cabinet 100 sends a first near field communication signal according to a certain frequency, and in the closing process of the door body 200, after the door body 200 receives the first near field communication signal sent by the cabinet 100, the door body 200 sends a second near field communication signal outwards. The second near field communication signal is generated after the door body 200 receives the first near field communication signal, so that the uniqueness of the signal can be ensured, the state of the door lock is controlled based on whether the cabinet body 100 receives the second near field communication signal, and the phenomenon of lock cheating can be avoided.
It should be noted that the first target device may also be the door body 200, and in this case, the second target device is the cabinet 100. In the closing process of the door body 200, after the cabinet 100 receives the first near field communication signal sent by the door body 200, the cabinet 100 sends a second near field communication signal to the outside. Furthermore, the first target device may transmit the first near field communication signal according to its own predetermined program, or may be adjusted by the frequency operation procedure, for example, control the first target device to transmit the first near field communication signal according to the first frequency.
Based on the determination result of the signal determination step, the manner of controlling the door lock state of the door body 200 may be various, for example:
the first mode is mainly for a case that the mounting process of the NFC master device 310 and the NFC slave device 320 is high, that is, the mounting process of the NFC master device 310 and the NFC slave device 320 can meet the requirement that the NFC master device 310 can receive the second near field communication signal sent by the NFC slave device 320 only when the door body 200 is attached to the frame of the cabinet 100, that is, when the door body 200 is closed to the cabinet 100.
In this case, as shown in fig. 2, the door locking method includes the steps of:
step 100: determining whether the first target device receives a second near field communication signal;
step 2011: the first target device receives the second near field communication signal, which indicates that the door body 200 is closed in the cabinet 100 at this time, and determines whether a door opening request signal is received; the door opening request signal is a signal sent by a user in a code scanning or face recognition mode and the like;
step 2012: if the door opening request signal is not received, controlling the door lock to be in a lock falling state; the "controlling the door lock in the lock-out state" referred to herein can be divided into two cases: one is that if the door lock is in an open state, the door lock is controlled to be locked; in another case, if the door lock is in a lock-off state, the door lock may be controlled to maintain the current state. In order to distinguish between the two cases, before the step 2011 is executed, a door lock determination step may be executed to determine whether the door lock is in an open state.
Step 2013: and receiving the door opening request signal, indicating that the user takes the goods, and controlling the door lock to be in an opening state.
Step 2021: the first target device does not receive the second near field communication signal, which indicates that the door body 200 is opened at the moment, and determines whether a door opening request signal is received or not;
step 2022: when the door opening request signal is not received, it is indicated that the door body 200 is abnormally opened, that is, the door body 200 is opened under the condition that the user does not request to open the door in a regular mode such as code scanning or face recognition, and a condition of opening the door violently may exist, so that a man-shaped image of the periphery of the container and/or a control alarm can be obtained at the moment;
step 2023: if the door opening request signal is received, it indicates that the door body 200 is normally opened, and then to improve the detection sensitivity, the first target device is controlled to increase the frequency of sending the first near field communication signal, that is, the first target device is controlled to send the first near field communication signal according to the second frequency, where the first frequency is greater than the second frequency.
In addition, considering that the user may forget to close the door for settlement after shopping, in order to remind the user in time, the method further comprises the following steps:
step 2024: receiving the door opening request signal, controlling the timing
Step 2025: within the preset time duration, the first target device does not receive the second near field communication signal, that is, the door body 200 is not closed in the cabinet body 100, and then the voice prompt is controlled to be played to remind the user to close the door for settlement. Wherein the expected timing duration can be determined according to the shopping duration common to the user.
The second mode is mainly directed to the case that the mounting processes of the NFC master device 310 and the NFC slave device 320 are not too high, that is, the mounting processes of the NFC master device 310 and the NFC slave device 320 cannot meet the condition that the NFC master device 310 can receive the second near-field communication signal sent by the NFC slave device 320 only when the door body 200 is attached to the frame of the cabinet 100, and it is likely that the NFC master device 310 can receive the second near-field communication signal sent by the NFC slave device 320 when a gap still exists between the door body 200 and the cabinet 100.
In this case, in order to improve the reliability and accuracy of the detection, on the basis that the first target device receives the second near field communication signal, the strength of the second near field communication signal needs to be determined, specifically, as shown in fig. 3, the door lock method includes the following steps:
step 100: determining whether the first target device receives a second near field communication signal;
step 2031: when the first target device receives the second near field communication signal, it indicates that the door body 200 is already closed in the cabinet body 100, or the door body 200 is not yet closed in the cabinet body 100, that is, a gap still exists between the door body 200 and the cabinet body 100, and at this time, it may be determined whether the intensity of the second near field communication signal is greater than the preset signal intensity;
step 2032: if the strength of the second near field communication signal is greater than the preset signal strength, it indicates that the door body 200 is closed in the cabinet 100, and at this time, it may be determined whether a door opening request signal is received; the door opening request signal is a signal sent by a user in a code scanning or face recognition mode and the like;
step 2033: if the door opening request signal is not received, controlling the door lock to be in a lock falling state; the "controlling the door lock in the unlocked state" can be divided into two cases: one is that if the door lock is in an open state, the door lock is controlled to be locked; in another case, if the door lock is in a lock-out state, the door lock may be controlled to be kept in the present state. In order to distinguish the two cases, before step 2031 is performed, a door lock determination step may be performed to determine whether the door lock is in an open state.
Step 2034: and receiving the door opening request signal, indicating that the user takes the goods, and controlling the door lock to be in an opening state.
Step 2041: if the strength of the second near field communication signal is not greater than the preset signal strength, it indicates that the door body 200 is not closed in the cabinet body 100 at this time, and it is determined whether a door opening request signal is received;
step 2042: the door opening request signal is not received, which indicates that the door body 200 is abnormally opened, that is, the door body 200 is opened under the condition that the user does not request to open the door in a regular mode such as code scanning or face recognition, and the like, and the door can be opened violently, so that the people-type image of the periphery of the container and/or control alarm can be obtained at the moment;
step 2043: if the door opening request signal is received, it indicates that the door body 200 is normally opened, and then to improve the detection sensitivity, the first target device is controlled to increase the frequency of sending the first near field communication signal, that is, the first target device is controlled to send the first near field communication signal according to the second frequency, where the first frequency is greater than the second frequency.
In addition, considering that the user may forget to close the door for settlement after shopping, the method also comprises the following steps in order to remind the user in time;
step 2044: receiving the door opening request signal, controlling the timing
Step 2045: within the preset time duration, the strength of the second near field communication signal is not greater than the preset signal strength, which indicates that the door body 200 is not closed in the cabinet body 100 at this time, and then the voice prompt is controlled to be played to remind the user to close the door for settlement. Wherein the expected timed duration may be determined based on the duration of shopping for most users.
