20100207723
1. Technical Field
The present disclosure relates to locks, and particularly, to an electrically locking device and an electric lock system and an unlocking method thereof.
2. Description of Related Art
Electric lock system has been developed, which allows people to open a door without a conventional key. The electric lock system includes various kinds of electric locks, such as an integrated circuit card (IC-card) electric lock and a radio-frequency-identification (RFID) electric lock. However, when these electric locks are used, people have to take with an IC card and an RFID card to unlock the electric lock. This is inconvenient.
Therefore, there is a need exist for an electrically locking device and an electric lock system and an unlocking method thereof, in which the above problem is eliminated or at least alleviated.
Referring to
The electrically locking device 100 includes a memory unit 102, a first input unit 104, a first processing unit 106, a first communication unit 110, a first notifying unit 112 and an electric lock 114.
The memory unit 102 is configured for storing an unlock code, a request code, and a request message. The unlock code, the request code and the request message may be predetermined/changed by a user of the electric lock system 10.
The first input unit 104 is configured for generating an input code according to the user's input. The first input unit 104 may include a keypad and/or a touch screen for the user to input. The first communication unit 110 is configured for transmitting the request message to the wireless communication device 200.
The first processing unit 106 is configured for comparing the input code with the request code and controlling the first communication unit 110 to transmit the request message to the wireless communication device 200 if the input code matches the request code.
The first communication unit 110 is further configured for receiving an unlock request code transmitted from the wireless communication device 200. The first processing unit 106 is further configured for comparing the received unlock request code with the unlock code and unlocking the electric lock 114 if the received unlock request code matches the unlock code. The first processing unit 106 is further configured for controlling the first notifying unit 112 to notify the user if the received unlock request code is different from the unlock code and if the input code is different from the request code. The first notifying unit 112 may include a light emitter and/or a sound emitter. The electric lock 114 may be attached to a door.
The wireless communication device 200 includes a second communication unit 204, a second processing unit 206, a second notifying unit 208, and a second input unit 210.
The second communication unit 204 is configured for receiving the request message transmitted from the first communication unit 110. The second processing unit 206 is configured for controlling the second notifying unit 208 to notify the user of the wireless communication device 200 according to the received request message. The second notifying unit 208 may include a light emitter and/or a sound emitter.
The second input unit 210 is configured for generating the unlock request code according to the user's input after the request message is received. The second input unit 210 may include a keypad and/or a touch screen for the user to input. The second processing unit 206 is configured for controlling the second communication unit 204 to transmit the unlock request code to the first communication unit 110.
The first communication unit 110 and the second communication unit 204 may include global system for mobile communications (GSM) units.
Referring to
It is note that the user changing the unlock code, the request code and the request message may be different from the user inputting the input code, and the request message can be sent to anyone of the users. For example, the user changing the unlock code, the request code and the request message may be a host of the house where the electric lock system 10 is applied, and the user inputting the input code may be a visitor to the house.
The electric lock system and an unlocking method thereof can allow people to open a door without a IC-card and a RFID card. Moreover, when a user of the electric lock system 10, such as a host, is not home, his visitor can enter his home with his authorization. This is convenient.
It is to be understood, however, that even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
