Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
For each intelligent door lock without a backup battery, real-time information is lost at the moment of system power failure, so that the intelligent door lock is usually started from the default time of an initialization state after the system is powered on again. Or even though each intelligent door lock may timely store the time information during power failure, when the system is powered on again, the real-time clock unit of the intelligent door lock will continue to move from the reserved time. Obviously, this may cause the problem of asynchronous time of the intelligent door lock.
Therefore, in the existing intelligent door lock equipment, due to the characteristics of the real-time clock circuit, most products supply power to the real-time clock circuit by adding a button battery in the intelligent door lock equipment so as to be used for guaranteeing normal operation during power failure after the system is powered off, and therefore after the system is powered on again, the intelligent door lock can be guaranteed to have correct real-time. Obviously, for places such as apartments, office buildings and residential households where a certain number of intelligent door locks exist, a button battery is installed on each intelligent door lock, and relatively high hardware cost is required. In addition, the internal button cell also needs to occupy a larger space, which increases the volume of the circuit board of the intelligent door lock.
Therefore, the invention provides a time management system, a gateway and a method of intelligent door locks, which can cancel the standby battery in each intelligent door lock by utilizing the gateway to carry out real-time clock synchronization of each intelligent door lock, thereby not only meeting the real-time clock synchronization requirement of the intelligent door lock after the system is recovered to be electrified, but also greatly reducing the hardware cost and the like.
The present invention will be described in detail with reference to specific examples.
Example 1
Referring to fig. 1, the present embodiment provides a time management system 1 for an intelligent door lock, which can be applied to time management of intelligent door locks in locations such as apartments, office buildings, and residential houses, especially for those intelligent door locks that do not have a battery backup for supplying power to a real-time clock circuit after the system is powered off. Specifically, the time management system 1 of the intelligent door lock mainly includes a gateway 10 and at least one intelligent door lock 20, the gateway 10 and the intelligent door lock 20 establish a network topology, and the gateway 10 includes a real-time clock unit 110 and a backup battery 120 connected to the real-time clock unit 110.
Specifically, when the system is powered off, the backup battery 120 is used to supply power to the real-time clock unit 110 so that the real-time clock unit 110 provides real-time information. When the system is powered on, the gateway 10 reads the real-time information from the real-time clock unit 110 and performs real-time clock synchronization for all the intelligent door locks 20 in the network topology.
In this embodiment, the gateway 10 is configured to perform real-time clock synchronization on the connected intelligent door lock 20. Specifically, the gateway 10 establishes a connection with each intelligent door lock 20 within its signal range, and performs local area networking with all the connected intelligent door locks 20 to form a network topology. For example, if there are multiple floors and there are multiple intelligent door locks 20 on each floor, the intelligent door locks 20 on the same floor may be optionally assigned to a gateway 10, so that the connection between each intelligent door lock 20 and the corresponding gateway 10 is stable, and the like.
With the backup battery 120, the gateway 10 can ensure that the real time clock unit 110 still operates properly during system power down. Thus, when the system is powered back up, the gateway 10 has the correct real-time information. At this time, the real-time information may be issued to each of the intelligent door locks 20 in the network topology, so that each of the intelligent door locks 20 may perform time synchronization according to the real-time information.
For example, after the gateway 10 is powered back, the time synchronization command including the real-time information may be broadcasted to all the intelligent door locks 20 in the network topology, and after each intelligent door lock 20 receives the broadcast command, the respective time state thereof may be updated according to the real-time information, so as to achieve the purpose of time synchronization. Optionally, the intelligent door lock 20 after the real-time clock synchronization may send a synchronized signal to the gateway 10 to inform that the clock synchronization is successful.
Further, when the system is in a power-on state, the gateway 10 may be further configured to monitor a connection state of the intelligent door lock 20 in the network topology in real time, and perform real-time clock synchronization on the intelligent door lock 20 that is in connection restoration when it is monitored that the disconnected intelligent door lock 20 is in connection restoration.
Specifically, in consideration of situations such as power failure of a part of the intelligent door locks 20, in order to ensure that the intelligent door locks 20 can obtain correct time information in time after power up is resumed, real-time monitoring can be performed through the gateway 10, and when it is monitored that the intelligent door locks 20 are reconnected, the real-time information can be separately transmitted to the intelligent door locks 20, so that the intelligent door locks 20 powered up again after power failure can obtain real-time, and further, subsequent synchronous management of the intelligent door locks 20 is ensured, such as the transmission of some temporary passwords or the transmission of one-time passwords.
Further, when the system is in the power-on state, the gateway 10 may be further configured to monitor a new joining state of the intelligent door lock 20 in the network topology in real time, and perform real-time clock synchronization on the newly joined intelligent door lock 20 when it is monitored that the newly joined intelligent door lock 20 joins the network topology.
Specifically, in consideration of the replacement or addition of some intelligent door locks 20, in order to ensure that the intelligent door lock 20 can perform time synchronization at the first time, when the gateway 10 detects the addition of the intelligent door lock 20, the intelligent door lock 20 can be added to the network topology at the first time and issue a real-time synchronization instruction to the network topology, so that the newly added intelligent door lock 20 can acquire real-time, and further can perform management operations such as password issuance to the newly added intelligent door lock 20.
Further, when the system is in a power-on state, the gateway 10 may also broadcast real-time information to all the intelligent door locks 20 in the network topology according to a preset time interval, so that the intelligent door locks 20 that need clock synchronization perform the real-time clock synchronization.
Illustratively, some time error may develop during the continuous operation of the real time clock circuit of the intelligent door lock 20. To reduce or avoid the time error, real-time information may be periodically broadcast to each intelligent door lock 20 through the gateway 10 so that each intelligent door lock 20 compares with its own time. If there is a deviation, the intelligent door lock 20 can perform clock synchronization.
Optionally, for each intelligent door lock 20, a synchronized signal may be sent to the gateway 10 after each real-time clock synchronization to inform that the clock synchronization was successful. Of course, if the clock synchronization fails, the clock synchronization may be actively requested from the gateway 10.
Further, as shown in fig. 2, the time management system 1 of the intelligent door lock 20 may further include a cloud server 30, where the cloud server 30 is communicatively connected to the gateway 10, and is configured to send real time information to the gateway 10 when receiving a time calibration request sent by the gateway 10, so as to enable the gateway 10 to perform time calibration. This is because some time deviation may also occur during the long-term continuous operation of the real-time clock unit 110 of the gateway 10, and the gateway 10 may periodically request time calibration from the cloud server 30, so as to ensure the time accuracy of all the intelligent door locks 20 in the system, and the like.
In this embodiment, each smart door lock 20 may include, but is not limited to, one or more of a plurality of short-distance communication modules including a ziebee module, a Z-wave module, a 433 communication module, a bluetooth module, and a LoRa module, and may further include a long-distance communication module such as a WiFi module.
Correspondingly, in this embodiment, the gateway 10 may be a ZigBee gateway, a Z-wave gateway, a 433 gateway, a bluetooth gateway, an RFID gateway, or a wifi gateway. It should be understood that the gateway 10 is used for communication protocol conversion between different networks, and can perform local area network networking with each intelligent door lock 20 to implement communication and management of each intelligent door lock 20, and can be connected to the cloud server 30 in an uplink manner to implement cloud data transmission, etc.
According to the time management system of the intelligent door lock, the standby battery used for supplying power to the real-time clock unit is arranged in the gateway, the standby battery in each intelligent door lock is cancelled, the time synchronization requirement of each connected intelligent door lock can be met, and meanwhile hardware cost is greatly reduced. As the standby battery is saved, the occupied space of the circuit board of each intelligent door lock can be reduced, and the complexity of hardware layout can be reduced.

The time management method of the intelligent door lock mainly comprises the following two steps.
