The transponder chip 1 is small enough to be carried by a user, has its own ID code, and uses electromagnetic waves transmitted from the antenna module 2 as operating power.

The antenna module 2 emits an electromagnetic wave signal generated from the transponder chip set 3 to the air to supply operating power to the transponder chip 1, and transmits the electromagnetic wave generated from the transponder chip 1 to the transponder chip set ( 3) serves to deliver.

At this time, the antenna module 2 may be mounted in a position where external projection or electromagnetic waves may pass well and a user may easily approach the transponder chip 1.

The transponder chip set 3 is embedded in the control unit, emits electromagnetic waves through the antenna module 2, and receives the contents of the transponder chip 1 received through the antenna module 2.

The lock / unlock actuator 12 uses a motor or a solenoid.

In the case of the transponder chip 1 applied to the present invention, since the generated electromagnetic wave requires a much lower output than the remote control, it is very advantageous in the EMI (Electromagnetic Interfereance) countermeasure and the code complement countermeasure.

The operation of the present invention made as described above will be described with reference to FIGS. 2 to 7 for each function as follows.

First, a method of controlling an opening and closing device using a transponder will be described with reference to FIG. 2.

Before determining whether the transponder chip 1 approaches, the microcomputer 11 always compares the state of the current lock / release mechanism 13 through the lock / release detection sensor 14 (S100).

If it is determined in S100 that the device is open, the current state is stored as an open state (S110). In such a situation, it is determined whether or not the transponder chip 1 is approached (S111). If it is determined that the transponder chip 1 is approached, the transponder ID is compared with the preset ID (S112).

If the transponder ID is correct, in order to release the lock / release mechanism 13, a signal is output to the actuator driver 10 to control the lock / release actuator 12 to the lock side (S113).

However, if it is determined that the transponder has not approached in S111 and the transponder ID is not matched in S112, the transponder is continuously opened (S110).

When the locking function is performed in S113, the locked state is compared and judged by a signal applied from the locking / release detecting sensor 14 (S114). When the locking function is determined to be locked, the speaker is used by using the data of the sound source chip set 5. This situation is informed (for example, a voice such as "door locked" is output) (S115).

Meanwhile, if it is determined in S100 that the device is locked, the current state is stored in the locked state (S120). In this situation, it is determined whether or not the transponder chip 1 is approached (S121). If it is determined that the transponder chip 1 is in the approached state, it is determined whether the ID of the transponder is correct (S122).

If the transponder ID is correct, a signal is output to the actuator driver 10 to release the lock / release mechanism 13 to control the lock / release actuator 12 to the release side (S123).

In addition, if it is determined that the transponder ID does not fit inside, the process continues to be locked (S120).

When the release function is performed in S123, the open state is compared and judged through a signal applied from the lock / release detection sensor 14 (S124), and when it is determined that the open state, the voice is notified of the situation (eg, “the door is opened”). Sound ”is outputted (S125).

Therefore, the opening and closing control using the transponder chip 1 is completed through the above process.

In addition, the opening and closing operation may be performed using the internal opening and closing switch without the transponder chip 1, which will be described with reference to FIG. 3.

Before determining whether the internal open / close switch is operated, the microcomputer 11 always compares the state of the current lock / release mechanism 13 through the lock / release detection sensor 14 (S200).

If it is determined in S200 that the device is in an open state, the current state is stored as an open state (S210). In such a situation, the operation of the internal open / close switch is judged in comparison (S211) and when the internal open / close switch is determined to be in the closed operation state, a lock / release actuator is output by outputting a signal to the actuator driving unit 10 to lock the lock / release mechanism 13. Control 12 to the locking side (S212).

However, if it is determined in S211 that the internal open / close switch is not in the operating state, the process continues to be opened (S210).

When the locking function is performed in S212, the locked state is compared and judged by the signal applied from the locking / release detecting sensor 14 (S213). If the locked state is determined, the voice is notified of the situation (for example, “the door is locked). Sound ”is output (S214).

Meanwhile, if it is determined in S200 that the device is locked, the current state is stored in the locked state (S220). In such a situation, it is determined whether the internal on / off switch is operated (S221), and when the internal on / off switch is determined to be in the open operation state, a signal is output to the actuator driver 10 to release the lock / release mechanism 13 to lock / unlock the actuator. (12) is controlled to the release side (S222). However, if it is determined in S221 that the internal open / close switch is not operated, the process continues to be locked (S220).

When the release function is performed in S222, the open state is compared and judged through a signal applied from the lock / release detection sensor 14 (S223), and when it is determined that the open state, the voice is notified of the situation (for example, "the door is opened"). Sound ”is outputted” (S224).

Therefore, the opening and closing control using the internal opening and closing switch is completed through the above process.

The process of controlling the ingress / release of the alarm state by the transponder will be described at the same time with reference to FIG. 5 for the process of controlling the ingress / release of the alarm state by the internal open / close switch.

If the current switching state is in the open state (S300, S400) and the state is switched to the locked comparison (S310, S410), if the state is switched to the locked state when the transponder chip (1) using the set time ( Example: 3 seconds) if you approach the transponder once again within the alarm state (S311), if you use the internal open and close switch, if you press the lock switch once again sends out the voice guidance to enter the alarm state (S411).

When the same transponder chip 1 is approached within the set time (S312) (when the internal switch is used, it is determined whether the lock switch is operated), and if it is determined that the transponder chip 1 is not approached, the present control is performed. When it is determined that the access is finished, it is determined whether the window is well closed by a signal applied from the window open state value input unit 6 (S313 and S413).

When it is determined that the window is open in S313 and S413, the window is opened and the voice is notified when the transponder is approached again (by pressing the lock switch) within the set time (S314, S414).

Then, it is determined whether the transponder chip 1 is approached again (operating the lock switch) within the set time (3 seconds), and when it is determined that the transponder chip 1 is re-accessed (lock switch operation), it is notified that the alarm device is set (S316). S416) If it is determined that no re-access is made, the control ends.

If it is determined in S313 and S413 that the window is well closed, the alarm device is set (S316, S416), the alarm state is set (S317, S417), and the state is maintained (S318, 418). If it is determined that the comparison is made (S319, S419) has been switched to open (S320, S420) and the voice is released (S321, S421).

Through this process, alarm in / out is controlled.

Hereinafter, a control process for external intrusion will be described with reference to FIG. 6.

Comparing whether the alarm is set state (S500), if the alarm state through the signal applied from the window open detection unit 6 determines whether the window is additionally open in preparation for the alarm (S510) external shock detection unit It is determined whether there is an external shock through the signal applied from (17) (S520).

If it is detected in S510 that the window is additionally opened in preparation for the alarm setting or if there is an external shock in S520, the emergency call 15 is activated (S530) and the siren 4 is operated (S540).

Then, it is determined whether the transponder chip 1 is approached (S550). If there is an access, the ID is determined (S553). It is determined whether there is an operation of the internal open / close switch (S551), and it is determined whether the time set in the timer has elapsed. (S552), if the ID of the transponder chip (1) is correct or if the internal open / close switch (16) has been operated or the set time has elapsed, the siren is terminated (S554) to prevent noise.

Next, the control process for determining the window open state and the alarm state in preparation for the case where there are several windows will be described with reference to FIG. 7.

Before describing the control process, referring to the installation method of the window opening detection unit 6, the window opening detection unit collects the signals transmitted from each window opening state input unit 6 into a parallel port and converts them into hexadecimal numbers. (Closed state = "1", open state = "0") is transmitted to the microcomputer 11, the microcomputer 11 performs the command by judging the closed / open state of the window when the alarm state ingress request.

The intrusion can be determined by setting the value of the lower unit of the window opener at the time of the alarm state as the reference value and reading the value of the lower unit of the window opener each time and comparing it with the reference value. have.

In the state in which the principle is applied, the alarm inrush control process according to the window opening is determined as follows, if there is an alarm inrush request (S600), when it is determined that the data is received from the window detection unit lower unit (S610) based on the data It is determined whether all windows are closed (S611).

If in S611 all windows are not closed, it warns that the window is open (S630) and compares whether to enter the alarm state even in the current state (S631). If it is determined that the alarm is in the current state, the current window is opened. The value of the sensing lower unit is set as a reference value (S620). Of course, even when all windows are closed in S611, the value of the window open detection lower unit is set as the reference value (S620).

When the reference value is set, the system enters an alarm state (S621) and continuously receives data from the window open detection lower unit (S622) and compares the reference value with the judgment after determining whether the state has changed (S623).

If the received data is different from the reference value, the emergency call and the siren are operated (S624), and if there is an alarm state release request (S625), if there is an alarm release request, the emergency call and the siren are stopped (S626). If there is no alarm condition release request at S625, it is returned to S622 and continues to receive data about the window open state from the window open detection lower unit.

The non-contact switchgear using the non-powered transponder described above and its control method may be additionally changed in addition to the non-contact switchgear using the non-powered transponder and the control method of the present invention, the contactless switch using a non-powered transponder is changed The device and its control method are included as part of the switchgear with the transponder of the present invention described above.

As described above, the present invention can open and close the device without a separate external operation such as key or number input by using a transponder chip, and eliminate the possibility of breaking the intruder's opening and closing device due to the external protrusion of the opening and closing part, Provides the convenience of operating the switchgear by accessing the transponder chip that the user is carrying without additional operation such as key number input and remote control button.The transponder is compact, so it can be molded or attached to the user's desired part. Wide range of application such as molding to key holder of hospitality such as condominium or hotel, and easy to counter EMI due to the use of electric field strength which is significantly lower than remote control device, easy to secure code, and loss of transponder chip. Set a different transponder ID in the EPROM using the Change Configuration feature of the transponder chipset. It is a very useful invention in the switchgear manufacturing industry because it has many side effects, such as the effect of preventing the use of lost and lost transponders.The modular design of each additional function makes it easy to differentiate products from low-cost to high-priced products.
