Description

Non-contact communication method and device thereof, non-contact access control device

The invention relates to a short-range wireless communication method, in particular to a contactless communication method.

Conventional access control devices are mainly used to control that only users with legal rights can use or access their protection targets, such as building locks, doors or safes (cabinet), computers, etc. Referring to FIG. 1, in the access control system by which the contactless card is used as the authentication, a contactless reader 101 of the access control device 10 actively scans whether there is a contactless card, such as an RFID card 11. Or a near field communication (NFC) mobile phone 12 that is modeled as a contactless card mode is approached, and if so, the access control device 10 starts wireless communication with the RFID card 11 or the NFC mobile phone 12 to perform a verification procedure. After the RFID card 11 or the NFC mobile phone 12 completes (passes) the verification process, the access control device 10 opens the RFID card 11 or the user of the NFC mobile phone 12 to use or access a protection target 13 of the access control device 10.

Considering also the reaction time and power consumption of the contactless reader 101 of the access control device 10, the non-contact reader 101 generally performs interval scanning. That is, as shown in FIG. 2, after a standby time Ts is separated between the two active scanning times Ta, the contactless reader 101 enters the standby time Ts after the end of the active scanning time Ta, and is completely presented. In the standby state when the work is not working, the contactless reader 101 does not detect whether the RFID card 11 or the near field communication mobile phone 12 is close to save power consumption until the next active scan time Ta arrives. The RFID card 11 or the near field communication handset 12 is measured. Therefore, the reaction time of the non-contact reader 101 will be slowed due to the influence of the standby time Ts. Therefore, if the reaction time is to be accelerated, the standby time Ts of the contactless reader 101 (or the standby time Ts is cancelled) needs to be shortened, but as a result, the power consumption of the contactless reader 101 is relatively increased; If the standby time Ts of the non-contact reader 101 is increased in order to reduce the power consumption of the contactless reader 101, the reaction time of the non-contact reader 101 will be relatively extended. Therefore, how to reduce the power consumption and reaction time of the access control device 10 at the same time is one of the problems to be solved by the present invention.

Referring to FIG. 3, the contactless communication method of the present invention is applied to a non-contact access control device 300 of the present invention to enable contact with a contactless card 4, for example, to support near field communication (hereinafter). NFC card or RFID card, etc., referred to as NFC, and a mobile communication device 5 (hereinafter referred to as mobile communication device 5) that is modeled as a contactless reader/writer mode, such as a smart phone, a PDA, a tablet computer, an iPAD, etc. Contactless wireless communication. It should be noted that the existing mobile communication device supporting contactless wireless communication can operate in a point-to-point mode that simulates a contactless card mode, works in short-distance data transmission with another mobile communication device, and Work in a simulation into a contactless reader mode. Therefore, the contactless card 4 of the embodiment It can also be a mobile communication device that simulates a contactless card mode.

As shown in FIG. 3, a preferred embodiment of the contactless access control device 300 mainly includes a contactless communication unit 31, a controller 32, a database 33, and an access control unit 6. The contactless communication unit 31, the controller 32 and the database 33 can be integrated in a separate contactless communication device 3, and the contactless communication unit 31 can operate in an active scan whether or not the contactless card 4 is close to An active scanning mode, and a passive listening mode of passive listening to the proximity of the mobile communication device 5. The controller 32 is electrically coupled to the contactless communication unit 31 for controlling the operation mode of the contactless communication unit 31. The database 33 stores a usage object data 34, which mainly records whether the object using the non-contact communication device 3 is the contactless card 4 or the mobile communication device 5, or both, and if the non-contact communication device 3 is used When there are several types of contact cards 4, these types of contactless cards 4 are also recorded in the use object data 34.

The access control unit 6 is electrically coupled to the controller 32 and a protection target 7 to control the access control of the protection target 7, and is controlled by the controller 32 to release the protection of the protection target 7, such as powering the protection target 7 to unlock.

Referring to FIG. 4 again, it is a flowchart of a preferred embodiment of the contactless communication method of the present invention. First, after the non-contact communication device 3 is turned on, the controller 32 reads the database as shown in step S1. In the use object data 34 of 33, it is judged whether or not only the contactless card 4 is recorded in the use target data 34, and if so, step S2 is executed to control the non-contact communication unit 31 to operate in the active scan mode to actively scan the contactless card. 4 is close, that is, a scan signal is transmitted to detect whether there is a contactless card 4 If not, the contactless communication unit 31 will receive a message sent back by the contactless card 4, and then the controller 32 performs subsequent verification through the contactless communication unit 31 and the contactless card 4. The program, and after the verification process is completed, that is, after the contactless card 4 passes the verification process, the controller 32 controls the access control unit 6 to release the access control 7 to enable the user of the contactless card 4 to use or access the program. Protect the subject 7 (eg building locks, doors or safes, computers...etc.).

As shown in FIG. 5, the active scanning mode of the embodiment is interval scanning, that is, a standby time Ts is separated between two active scanning times Ta, wherein the lengths of the active scanning time Ta and the standby time Ts can be as needed. Adjusted flexibly.

Further, in step S1, when the controller 32 confirms that the non-contact card 4 of the N(N≧2) type is recorded in the use object data, as shown in FIG. 6, the controller 32 controls the contactless communication unit. 31 sequentially scanning the N types of contactless cards 4 in the N active scanning times Ta arranged in sequence, and each of the two active scanning times Ta is separated by a standby time Ts.

Going back to step S1, if the result of the determination is no, proceeding to step S3, the controller 32 determines whether only the mobile communication device 5 is recorded in the use target data 34, and if so, executing step S4 to cause the contactless communication unit 31 to operate. The passive listening mode enables passive listening to see if the mobile communication device 5 is close. That is, as shown in FIG. 7, in the passive listening mode, the contactless communication unit 31 simulates a contactless card mode, such as an NFC card mode or an RFID card mode, so that it only needs to passively listen (receive) NFC actions. a scanning signal transmitted by the communication device 5 without actively transmitting a scanning signal, Therefore, it consumes less power than the active scan mode. In addition, in the passive listening mode, since the contactless communication unit 31 is not in a completely inactive standby state, when it receives the scan signal transmitted by the mobile communication device 5, it can immediately return (respond) the message to the mobile communication. The device 5 enables the controller 32 to perform subsequent verification procedures with the mobile communication device 5 through the contactless communication unit 31 without delay in response time. And similarly, after the mobile communication device 5 completes (passes) the verification procedure of the controller 32, the controller 32 causes the access control unit 6 to release the protection target 7 from the access control unit 5.

Returning to step S3, if the determination result is negative, the controller 32 proceeds to step S5 to determine whether the non-contact card 4 and the mobile communication device 5 are simultaneously recorded in the use target data 34, and if so, step S6 is executed to control the non-contact. The contact type communication unit 31 alternately operates in the active scan mode and the passive listening mode, that is, as shown in FIG. 8, the contactless communication unit 31 actively scans whether there is a contactless card in an active scan time Ta of the active scan mode. 4 is close, and in a passive listening time Tp of the passive listening mode, passively listening (receiving) whether the mobile communication device 5 transmits a scanning signal, wherein the lengths of the active scanning time Ta and the passive listening time Ts can be flexibly adjusted according to actual needs. . Thereby, compared with the conventional access control device 10, the non-contact communication unit 31 can reduce power consumption and reduce the reaction time to the mobile communication device 5 in the passive listening mode.

In addition, as shown in FIG. 9, in order to further save power consumption, a standby time Ts may be further separated between the passive listening time Ts and the active scanning time Ta, that is, the contactless communication unit 31 may be after the passive listening mode ends. , first enter the standby state (not working state) for a while, then re-execute Active scan mode.

Moreover, in step S5, when the controller 32 confirms that the non-contact card 4 of the N(N≧2) type is recorded in the use target data, the non-contact communication unit 31 is placed as shown in FIG. The N active scanning times Ta sequentially scan the N types of contactless cards 4, and listen to the mobile communication device 5 at N passive listening times Tp interposed between the N active scanning times Ta. In addition, the length of the N active scanning times Ta and the length of the N passive listening times Tp are not necessarily fixed or identical, and may be elastically rounded according to actual needs.

Going back to step S5, if the result of the determination is no, it means that no contactless card 4 or mobile communication device 5 is recorded in the use target data, then, in step S7, the controller 32 can control the contactless communication unit 31 to enter a Standby mode for suspending work.

In addition, a trigger button 35 electrically coupled to the controller 32 may be disposed on the contactless communication device 3, and when the contactless card 4 or the mobile communication device 5 is to be added to the database 33 or the object data 34 is used. In the meantime, a trigger signal can be sent to the controller 32 by pressing the trigger button 35, so that the control contactless communication unit 31 can selectively operate in the active scan mode, the passive listening mode, the standby mode, or alternately operate in the active scan mode. And one of the passive listening modes, whereby the contactless communication unit 31 can be wirelessly communicated with the contactless card 4 or the mobile communication device 5. Of course, in addition to the trigger button 35, the trigger signal can also be generated by another controller or processor (not shown) of the contactless communication device 3, for example, when another controller or processor receives a mobile communication device. a new one of 5 When the user notification is added, a trigger signal is sent to the controller 32 to cause the control contactless communication unit 31 to alternately operate in the active scan mode and the passive listening mode, or to monitor the battery level of another controller or processor. The module (not shown) determines that a battery (not shown) that supplies power to the contactless communication device 3 is in a low battery state, and then sends a trigger signal to the controller 32 to control the contactless communication unit 31 to operate. The passive listening mode, the standby mode, or alternately operate in the active scan mode and the passive listening mode.

In addition, it should be noted that the process steps of FIG. 4 are not static or unique. In other preferred embodiments of the present invention, steps S1 and S2 may be omitted, or steps S1, S2, S5, and S7 may be omitted. , that is, when the determination in step S3 is NO, regardless of whether the user object data 34 records only the contactless card, the non-contact card 4 and the mobile communication device 5 are recorded, or the non-contact card 4 and the mobile communication device are not recorded. 5. The controller 32 directly executes step S6 to cause the non-contact communication unit 31 to alternately operate in the active scan mode and the passive listening mode, so that the wireless communication with the contactless card 4 or the mobile communication device 5 is ready at any time.

Moreover, in another preferred embodiment of the contactless communication device 3 of the present invention, the database 33 can also be omitted, and the controller 32 directly controls the contactless communication unit 31 to alternately operate in the active scanning mode and the passive listening mode. It also achieves the effect of reducing power consumption while reducing reaction time.
