Description of Related Art
In recent years, with the growing awareness of home security, the access control system has been quite popular, and becomes the standard equipment of house or building. The visitor can notice the householder via pressing the doorbell when arriving at the entry. Then, the householder can real-time check the visitor located outside via the access control system, and control the door to open after checking that the visitor is harmless.
However, when using the access control system of the related art, the householder can only perform the control when he is inside of the house, once the householder leaves the house, the householder will be unable to control the access control system. Besides, the householder will be unable to open the door when forgetting to bring the key or access control card.
Besides, because all the doorbells of the related art are triggered by pressing its electronic button, when the electronic button is pressed frequently or pressed with an excessive force, the doorbells would fail and be unable to trigger.
Therefore, the access control system of the related art suffers above-mentioned problems, there is a need to find out a better and more effective solution to handle such problems.
The object of the present disclosed example is to provide a remote access control system supporting remote control and using a contactless doorbell.
In order to achieve the above objective, a remote access control system is provided which comprises a remote host connected to a mobile device via Internet, a proximity sensor doorbell triggering a doorbell signal when sensing a visitor approaches, a door lock device, and a gateway device connected to proximity sensor doorbell. The gateway device comprises a camera unit capturing a monitoring video, a network unit connected to Internet, a first wireless unit wirelessly connected to the door lock device, and a first control unit electrically connected to the camera unit, the network unit and the first wireless unit. The first control unit sends a first notification message to the mobile device via the remote host when recognizing that the captured monitoring video comprises image of the visitor, sends a second notification message to the mobile device via the remote host when receiving the doorbell signal, and controls the door lock device to unlock when receiving an unlocking message from the mobile device.

In cooperation with attached drawings, the technical contents and detailed description of the present disclosed example are described thereinafter according to a preferable embodiment, being not used to limit its executing scope. Any equivalent variation and modification made according to appended claims is all covered by the claims claimed by the present invention.
First, please refer to
As a relay host between the gateway device 10 and the mobile device 22, the remote host 20 can respectively establish the connections with the gateway device 10 and the mobile device 20. More specifically, the mobile device 22 can establish the connection with the remote host 20 for communication (such as logging in a user account, sending an unlocking message or sending the configuring parameters of the gateway device 10) after executing an application 220, the remote host 20 can forward the data received from the gateway device 10 to the mobile device 22, or forward the data received from the mobile device 22 to the gateway device 10. For example, the remote host 20 can receive the monitoring video or a monitoring voice from the gateway device 10 and forward it to the mobile device 22, simultaneously receive a returning video or a returning voice from the mobile device 22 and forward it to the gateway device 10. Thus, the mobile device 22 can perform the real-time video/voice streaming transmission with the gateway device 10 via the remote host 20 as directly establishing a connection with the gateway device 10, and lead the householder located at far-end to execute a real-time video/voice communication with the visitor located at the entry of the house. Preferably, the remote host 20 is mapped to a fixed IP address or a permalink.
Please be noted that most of the devices installed in the house and the mobile devices are connected to the Internet 40 via the different dynamic IP addresses currently. If the gateway device 10 and the mobile device 22 are unable to retrieve the current IP address each other, they are unable to directly establish the connection. Via making the connectable remote host 20 as the relay host, the present disclosed example can lead the gateway device 10 and the mobile device 22 to communicate each other under the status that the gateway device 10 and the mobile device 22 don't know the current IP address each other.
Although the gateway device 10 indirectly communicates with the mobile device 22 via the remote host 20 in this embodiment, this specific example is not intended to limit the scope of the present disclosed example. In another embodiment of the present disclosed example, the gateway device 10 can periodically/irregularly upload its current IP address to the remote host 20. When the mobile device 22 wants to establish the connection with the gateway device 10, the mobile device 22 can first connect to the remote host 20 for retrieving the current IP address of the gateway device 10, then directly establish a P2P connection with the gateway device 10 according to the retrieved IP address, and vice versa.

In another embodiment of the present disclosed example, the remote host 20 can further provide a reception-checking function. More specifically, the remote host 20 can check whether the gateway device 10 or the mobile device 22 has received the message forwarded by the remote host 20. Preferably, the remote host 20 can attach a receipt to the message or transfer the message via a TCP connection, and determine whether the gateway device 10 or the mobile device 22 is successful to receive the message according to whether the remote host 20 has received the receipt or the acknowledgement (ACK) packet from the gateway device 10 or the mobile device 22.
In another embodiment of the present disclosed example, the remote host 20 can further provide a message-broadcasting function. In this embodiment, the remote host 20 is to simultaneously connect a plurality of the mobile devices 22 (above-mentioned mobile devices 22 can be respectively hold by the different householders), wherein each mobile device has been verified (such as successfully logging in the user account). The remote host 20 can simultaneously forward the received message to all verified mobile device 22 when receiving the notification message (e.g. first notification message, second notification message or third notification message) from the gateway device 10. Thus, all the householders of the house can simultaneously receive the notification message, and assign one householder who is currently free or nearest to the house to process the event corresponding to this notification message.
In another embodiment of the present disclosed example, the present disclosed example further provided a recognition mechanism used in the wireless sensor network 42. In this embodiment, each external wireless device (e.g. door lock device 30, auxiliary sensor device 32, externally connected proximity sensor doorbell 12 or externally wirelessly connected human-machine interface 14) can dynamically generate an identifying data and transfer the generated identifying data to the remote host 20 via the gateway device 10 when first time establishing the connection with the gateway device 10. Then, the remote host 20 can make the identifying data of all the external wireless device connected to the gateway device 10 correspond to the user account of the householder, store above-mentioned data as a register identifying data and complete the registration procedure.
After that, the gateway device 10 could receive the register identifying data corresponding to the user account of the householder from the remote host 20 and store it in the memory unit 106. When wanting to send the signal or message to specific external wireless device (such as sending the unlocking/locking signal to the door lock device 30), the gateway device 10 simultaneously attach the register identifying data corresponding the specific external wireless device to the signal or message which the gateway device 10 wants to send to for making the receiving device have the ability to verify the source device. The external wireless device verifies whether the received register identifying data is correct (such as both register identifying data and identifying data being consistent) for determining whether the currently received signal or message came from the gateway device 10 according to the identifying data previously dynamically generated when receiving above-mentioned signal or message attached the register identifying data. If the received signal or message doesn't pass the verification, the external wireless device will not operate according to the received signal or message, and further issue a warning message or disconnect the connection. If passing the verification, the external wireless device will operate according to the received signal or message (such as unlocking).
Furthermore, when wanting to send the signal or message to the gateway device 10 (such as the proximity sensor doorbell sending the doorbell signal, the human-machine interface 14 (taking the interphone for example) sending the monitoring voice, the door lock device 30 returning the unlocked/locked message, the auxiliary sensor device 32 sending the trigger signal), each registered external wireless device can also simultaneously attach the identifying data to the signal or message which wants to send for making the receiving device have the ability to recognize the source device. The gateway device 10 can verifies whether the received identifying data is correct according to the register identifying data (such as both register identifying data and identifying data being consistent) when receiving the above-mentioned signal or message attached the identifying data. If the received signal or message doesn't pass the verification, the gateway device 10 will not execute the corresponded control according to the received signal or message, and further issue a warning message to the mobile device 22. If passing the verification, the gateway device 10 will execute the corresponded control according to the received signal or message.
The present disclosed example can effectively bind the gateway device 10 and the registered external wireless device(s) and enhance the network security via providing the recognition mechanism used in the wireless sensor network 42. Moreover, compare with using the fixed identifying data (e.g. device ID or MAC address) which is easy to fake, via using the dynamic identifying data, the present disclosed example can effectively reduce the probability of the malicious people hacking and destroying the remote access control sensor system via faking the identifying data.
As the skilled person will appreciate, various changes and modifications can be made to the described embodiment. It is intended to include all such variations, modifications and equivalents which fall within the scope of the present disclosed example, as defined in the accompanying claims.
