Example one
Fig. 1 is a block diagram of an intelligent door lock system according to an embodiment of the present disclosure. As shown in fig. 1, an intelligent door lock system includes:
the intelligent door lock is used for acquiring input unlocking information and sending a first signal to the switch module when the unlocking information is not matched with preset information;
the switch module is connected with the intelligent door lock and used for opening the intelligent gateway according to the first signal;
and the intelligent gateway is connected with the switch module and used for receiving the connection request of the first terminal in the starting state so that the first terminal can send the temporary password request in the connection state with the intelligent gateway.
When the unlocking information is matched with the preset information, the intelligent door lock is opened, signals are not sent to the switch module, the intelligent gateway is in a power-off state, and electric quantity is not consumed.
The unlocking information comprises a fingerprint and/or a password, and the switch module is a wireless signal receiver. The first terminal is a visitor's terminal.
The intelligent gateway is characterized in that a switch module in wireless connection with the intelligent door lock is additionally arranged in the connection between the intelligent door lock and the intelligent gateway, and the switch module can open or close the intelligent gateway according to signals received by the intelligent door lock or the intelligent gateway. The switch module is used as a device for starting the intelligent gateway, and the high-power intelligent gateway is controlled by the low-power wireless signal receiver, so that the working time of the intelligent gateway can be greatly reduced, and the consumption of electric quantity is reduced.
When the unlocking information detected by the intelligent door lock is inconsistent with the preset information, the intelligent door lock sends a first signal to the switch module of the intelligent gateway, and meanwhile, the intelligent door lock opens the Bluetooth. The visitor is connected to the intelligent door lock through terminals such as a mobile phone and then is connected to the intelligent gateway (or is directly connected to the intelligent gateway) and sends a temporary password request to the administrator, so that the intelligent gateway is opened only when the user requests the temporary password, the intelligent gateway is not in a long-term operation state, and the electricity consumption caused by the intelligent door lock and the whole equipment linked with the intelligent door lock is reduced.
Example two
On the basis of the above embodiment, the intelligent gateway is further configured to close when the intelligent gateway is not connected to the first terminal within a preset time.
Wherein the preset time may be 2 minutes. It can be understood that, in practical applications, the preset time may be timed by the self-contained timer of the switch module, and when the connection between the intelligent gateway and the first terminal is not detected within the preset time, the intelligent gateway may be automatically turned off when the preset time is reached. In some cases, the intelligent gateway may also have a timer, so that the timer of the intelligent gateway may be used to automatically close the intelligent gateway when the set time is reached, which is not limited herein.
If the intelligent gateway does not establish a connection with the first terminal successfully within the preset time or does not receive the temporary password request, it may be that someone has triggered the unlocking information by mistake, and in order to further achieve the technical effect of saving the electric quantity, the intelligent gateway of this embodiment is closed when not being connected with the first terminal within the preset time.
EXAMPLE III
On the basis of the above embodiment, the intelligent gateway is further configured to send the temporary password request to a second terminal when the first terminal sends the temporary password request, and receive a response of the second terminal to the temporary password request.
And when the response of the second terminal to the temporary password request is to send the temporary password, the intelligent gateway is further used for sending the temporary password sent by the second terminal to the first terminal.
The intelligent door lock is further used for sending a second signal to the switch module when the input temporary password is acquired and the lock is unlocked, so that the intelligent gateway is closed.
In this embodiment, the second terminal is a terminal of an administrator, and the administrator has a temporary password authorization right. When the first terminal sends a temporary password request, the intelligent gateway sends the temporary password request to a terminal of an administrator and waits for the response of the administrator.
And if the response of the second terminal is to send the temporary password, the temporary password is sent to the first terminal through the intelligent gateway. The visitor can open the intelligent door lock according to the temporary password received by the first terminal, and specifically, the temporary password can be input through a touch screen/key of the intelligent door lock. When the intelligent door lock acquires the temporary password input by the visitor through the touch screen/key of the intelligent door lock and successfully unlocks the intelligent door lock, the intelligent door lock sends a second signal to the switch module to close the intelligent gateway, and it can be understood that the second signal is a signal generated by the intelligent door lock and used for driving the switch module to close the intelligent gateway.
It can be understood that, if the response of the second terminal is to send the temporary password, and after the intelligent door lock is successfully unlocked, the intelligent door lock sends a second signal to the switch module, so that the switch module closes the intelligent gateway. Therefore, the time of manual operation can be reduced, the power-on time of the intelligent gateway is reduced, and the power consumption is reduced.
It can be understood that if the response of the second terminal is to refuse to send the temporary password, the intelligent gateway feeds back information of refusing to send the temporary password to the first terminal and the intelligent door lock, and the intelligent door lock sends a second signal to the switch module to close the intelligent gateway, so that the power-on time of the intelligent gateway is reduced, and the power consumption is further reduced.
Example four
On the basis of the above embodiment, the first signal is a wireless signal, and the wireless signal is one of a WiFi signal, a bluetooth signal, and a ZigBee signal; the first signal is a signal generated by the intelligent door lock and used for driving the switch module to open the intelligent gateway, or a signal generated by a preset password which is input to enable the switch module to open the intelligent gateway.
The intelligent gateway is characterized in that a switch module in wireless connection with the intelligent door lock is additionally arranged in the connection between the intelligent door lock and the intelligent gateway, and the switch module can open or close the intelligent gateway according to signals received by the intelligent door lock or the intelligent gateway. When the unlocking information detected by the intelligent door lock does not accord with the preset information, the intelligent door lock sends a first signal to the switch module through one wireless signal of a WiFi signal, a Bluetooth signal and a ZigBee signal to drive the switch module to open the intelligent gateway, or sends a preset password input by a visitor to the switch module, so that the switch module opens the intelligent gateway (namely, the visitor can input the preset password for activating the switch module by using the touch screen of the intelligent door lock to activate the switch circuit, and the visitor can activate the intelligent gateway only by inputting the preset password), and meanwhile, the intelligent door lock opens the Bluetooth. The visitor is connected to the intelligent door lock through terminals such as a mobile phone and then is connected to the intelligent gateway (or is directly connected to the intelligent gateway) and sends a temporary password request to the user, and therefore the intelligent gateway is opened only when the user requests the temporary password, so that the intelligent gateway is not in a long-term operation state, and the electricity consumption caused by the intelligent door lock and the whole equipment linked with the intelligent door lock is reduced.
EXAMPLE five
Fig. 2 is a schematic flow chart of an unlocking method of an intelligent door lock provided in the embodiment of the present disclosure. As shown in fig. 2, an unlocking method of an intelligent door lock includes:
the intelligent door lock acquires input unlocking information, and when the unlocking information is not matched with preset information, a first signal is sent to the switch module; wherein, the unlocking information comprises a fingerprint and/or a password. The first signal is a signal which is generated by the intelligent door lock and drives the switch module to open the intelligent gateway, or a signal which is input by the visitor through (a touch screen/a key of) the intelligent door lock and is generated by a preset password for enabling the switch module to open the intelligent gateway;
the switch module turns on the intelligent gateway according to the first signal;
the method comprises the steps that the intelligent gateway receives a connection request of a first terminal in an opening state, so that the first terminal can send a temporary password request in a connection state with the intelligent gateway. And the intelligent gateway is closed when the intelligent gateway is not connected with the first terminal within the preset time.
The method of the embodiment is a method implemented based on the intelligent door lock system of the above embodiment.
When the first terminal sends the temporary password request, the intelligent gateway sends the temporary password request to the second terminal and receives the response of the second terminal to the temporary password request.
When the response of the second terminal to the temporary password request is to send the temporary password, the intelligent gateway sends the temporary password sent by the second terminal to the first terminal, and when the intelligent door lock obtains the temporary password input by the visitor and successfully unlocks the intelligent door lock, a second signal is sent to the switch module so as to close the intelligent gateway.
The intelligent gateway is characterized in that a switch module in wireless connection with the intelligent door lock is additionally arranged in the connection between the intelligent door lock and the intelligent gateway, and the switch module can be used for opening or closing the intelligent gateway according to signals received by the intelligent door lock or the intelligent gateway. When the unlocking information detected by the intelligent door lock is inconsistent with the preset information, the intelligent door lock sends a first signal to the switch module of the intelligent gateway, and meanwhile, the intelligent door lock opens the Bluetooth. The visitor is connected to the intelligent door lock through terminals such as a mobile phone and then is connected to the intelligent gateway (or is directly connected to the intelligent gateway) and sends a temporary password request to the administrator, so that the intelligent gateway is opened only when the user requests the temporary password, the intelligent gateway is not in a long-term operation state, and the electricity consumption of the intelligent door lock and the whole equipment linked with the intelligent door lock is reduced.
Fig. 3 is another schematic flow chart of an unlocking method of an intelligent door lock provided in an embodiment of the present disclosure, and fig. 3 is an example to illustrate an application example of the present disclosure.
In this example, the unlocking information is a fingerprint, the first signal is a wireless signal for driving the switch module generated by the intelligent door lock to open the intelligent gateway, and the intelligent gateway defaults to a closed state.
First, fingerprint recognition is performed. The intelligent door lock is automatically opened if the data of the fingerprint exists in the database, namely the fingerprint is matched with the preset fingerprint in the database, and a signal does not need to be sent to the switch module at the moment, so that the intelligent gateway is in a power-off state and does not consume electric quantity; if the database does not contain the data of the fingerprint, the intelligent door lock sends a wireless signal (in the form of WIFI, Bluetooth, ZigBee and the like) to the switch module. It can be understood that the user can preset the password of the switch circuit, so that the visitor can activate the intelligent gateway only by inputting the password under the condition of inconsistent fingerprint identification, and the switch circuit is activated by utilizing the preset password input by the touch screen/the keys of the intelligent door lock to open the intelligent gateway by the switch module.
And secondly, opening the intelligent gateway. When the switch module receives the first signal from the intelligent door lock, the switch module serves as a starting device, and the low-power wireless signal receiver is used for controlling the opening/closing of the high-power intelligent gateway, so that the working time of the intelligent gateway can be greatly reduced, and the consumption of electric quantity is reduced.
And thirdly, detecting whether the first terminal is connected with the intelligent gateway at regular time. After the intelligent gateway is turned on, the intelligent gateway performs wireless pairing within a preset time (for example, 2 minutes). During the preset time, the visitor can connect to the intelligent gateway through the first terminal (such as a mobile phone). If the intelligent gateway is not connected with the first terminal within the preset time, the intelligent gateway is automatically closed.
Again, a temporary password request is sent. After the mobile phone is connected with the intelligent gateway, a temporary password request sending interface appears on the mobile phone, so that a visitor can select to send a temporary password request. If the visitor determines to send the temporary password request, the intelligent gateway sends the temporary password request to a second terminal of the administrator through the Internet; if the visitor cancels the sending of the temporary password request or does not make any selection within the set time, the intelligent gateway is automatically closed.
And thirdly, the second terminal receives and responds to the temporary password request. In practical application, after receiving the temporary password request, the administrator can communicate with cameras such as a local cat eye and the like to observe the outdoor situation and then confirm and send the temporary password through the second terminal so as to respond to the temporary password request of the visitor, and at the moment, the temporary password is sent to the intelligent gateway first and then is transmitted to the mobile phone of the visitor. If the administrator refuses the temporary password request or does not respond within the set time, the response of the second terminal is that the temporary password is refused to be sent, and the intelligent gateway is automatically closed.
And finally, closing the intelligent gateway. And after the visitor receives the temporary password fed back by the second terminal and inputs the temporary password to successfully unlock the intelligent door lock, the intelligent door lock sends a second signal to the switch module again to close the intelligent gateway.
