The inside of the control device 2 includes a reception antenna 3 for easily receiving wireless data flying into the air, a high frequency radio receiver 17 for receiving a radio signal transmitted by the high frequency radio transmitter 1, and a system installation. A unique number setting switch 22 for changing and storing a unique number of radio data when changing a time or a high frequency wireless transmitting device 1, a door opening and closing device for driving a door lock 5 and an alarm 4; Driver 20, other device linkage device 23 for transmitting data to other devices in case of intruder, microprocessor 18 for controlling the abnormality and decoding and controlling the radio signal received from the high frequency radio receiver 17, It is composed of a power supply and a battery device 21 for the emergency reserve power supply in case of power failure and power failure of the control device 2, the inside of the high-frequency wireless transmission device (1) the lock switch 9 and the open switch 10 , The alarm device release switch 11 for stopping the warning sound or light generated by the alarm device 4, the micro device that receives a signal from the above (9, 10, 11) and collects a given unique number, door state and information. A processor 12, a high frequency radio transmitter 13 for generating collected data as a radio frequency radio signal, a transmission antenna 15 for transmitting radio data generated from the radio frequency radio transmitter 13, and high frequency radio transmission. It consists of a power supply and the battery device 16 for supplying the power of the window device 1.

The operation of the high frequency radio transmitting device 1 is a device for transmitting information about a door of a person as high frequency radio data, and the unique data and the information on the door are included in the radio data.

As for the unique numbers of the high frequency radio transmitter 1, 2 ³² (= 4,294,967,296) unique numbers are sequentially stored in the programming process of the microprocessor 12 in the high frequency radio transmitter 1.

Therefore, all unique numbers of the high frequency radio transmitter 1 are different, and each high frequency radio transmitter 1 has a unique number.

The unique number of the microprocessor 12 is stored in a nonvolatile memory called the EEPROM 14, and the EEPROM 14 is an element that always stores data regardless of the power source.

The microprocessor 12 of the high frequency radio transmitter 1 is processed according to a programmed program, and stored in advance with signals input from the locking switch 9, the opening switch 10, and the alarm release switch 11. In combination with the unique number, the communication data is generated in accordance with the communication protocol promised to each other, and the generated communication data is transmitted to the high frequency radio transmitter 13.

The high frequency radio transmitter 13 modulates the communication data transmitted from the microprocessor 12 into a high frequency radio frequency mutually agreed with the high frequency radio receiver 17 of the controller 2 through the transmission antenna 15. It is sent out.

The transmission antenna 15 is a device for transmitting high frequency radio data generated by the high frequency radio transmission apparatus 13 to be far away, and is designed to generate maximum efficiency at a frequency generated by the high frequency radio transmission apparatus 13.

When the data generated from the high frequency radio transmitter 1 reaches the receiving antenna 3 of the control device 2 via air waves, the high frequency radio receiver 17 demodulates the data to extract the received data. Thereafter, the received data generated by the microprocessor 18 is transmitted.

Received data transmitted from the high frequency radio receiver 17 receives the received data from the microprocessor 18. At this time, a large amount of error data carried in the airwaves is removed during the microprocessor 18 search, and the high frequency radio transmitter ( Only the communication data promised with each other 1) is left, and this communication data is analyzed to control the door locking device 5 and the alarm device 4 by driving the door opening and closing device and the alarm device driver 20.

If the door lock data is received from the high frequency wireless transmitter 1, the door lock 5 is operated to operate the door lock, and when the door opening data is received from the high frequency wireless transmitter 1, the door lock device ( 5) is released to open the door.

The door locking device 5 may be an electromagnetic force lock device driven by an electromagnet according to the type of door, a strike lock device operated by a small capacity solenoid, a dead bolt lock device operated by a large capacity solenoid, and the like.

The door lock signal is received from the high frequency wireless transmission device 1 to the control device 2 so that the door lock device 5 is operated, and the door lock is not detected from the door open / close detection device 6 after the door lock is operated. When the door lock state is artificially released after the door lock is detected, or when an intruder is detected from the intruder detection device 7, the control unit 2 generates a strong sound (10 dB) through the alarm device 4 or the like. By generating bright light, such as a warning light, the intruder can flee early to combat the thief.

At this time, by the powerful sound (10OdB) generated through the alarm device (4), the intruder's intrusion is known to the surrounding people and the surrounding people can cope with the situation, and at the same time the electrical connection device 23 The other device 8 can be operated by generating a signal.

The sound generated through the alarm device 4, when the alarm device 4 release signal is generated from the high frequency radio transmitter 1, the control device 2 receives this signal and immediately the alarm device 4 is released. do.

If there is no alarm device 4 release signal from the high frequency radio transmitter 1, the alarm device 4 continues to operate for 10 minutes, and after 10 minutes, the alarm device 4 stops operating itself.

This is because the sound generated through the alarm device 4 is too strong (10 dB), causing damage to people around when it continues to operate.

The door open / close detection device 6 is a device for detecting a door open / close state, and the intruder detection device 7 is a device detected when an intruder enters the inside.

Other device linkage device 23 is a device for informing the intruder intrusion to the other device 8, when the intrusion is detected from the door open and close detection device 6 or intruder detection device 7 when the door lock is operated. The unique number setting switch 22 is a switch for registering the unique number of the high frequency radio transmitting device 1 in the control device 2.

If the high frequency radio transmitter 1 is operated after the unique number setting switch 22 is operated (for example, the locking switch 9 of the radio frequency transmitter 1 is operated). The unique number in (1) is sent out and received by the control device 2, and the control device 2 registers the received unique number in the internal memory EEPROM 19.

The unique number registration is stored in the EEPROM 19 in the control device 2, so that the data stored when the power is turned off is not erased.

If the high frequency radio transmitter 1 is lost, purchase a new high frequency radio transmitter 1, operate the unique number setting switch 22 of the control unit 2, and re-register it. The unique number is erased, the newly received unique number is registered, and even if the lost high frequency radio transmitter 1 is operated, the control device 2 does not operate because the unique number is deleted.

The power supply and battery device 21 is a device for supplying the power of the control device 2, when commercial AC power is supplied, converts AC into DC to supply power to the control device 2 and to charge the battery.

When AC power is out of power, the controller 2 supplies power to the battery by a charged battery.

The effect of the present invention is to open and close the door lock (5) by the high frequency wireless transmission device 1 by high frequency wireless data communication, it is possible to open and close the lock without a lock exposed to the outside, the physical force from the outside There is no risk of damage to the locking device, and it can be completely secured from malfunction by others, and because the unique number of the high frequency wireless transmission device 1 is different, it cannot be duplicated, and if lost, the control device 2 and the door By purchasing only a new high frequency radio transmitter 1 at a low cost without replacing the locking device 5 and re-registering the unique number of the radio frequency transmitter 1 purchased, the malfunction of the existing high frequency radio transmitter 1 is prevented. At the same time, it can perform the complete security function of the new high frequency wireless transmitter (1), and no one can open and close the door without the high frequency wireless transmitter (1). Implement a full security device.

If an external intruder enters the door, the alarm device 4 is operated by the door open / close detection device 6 or the intruder detection device 7, and theft is prevented by prematurely eradicating the intruder with a strong warning sound (100 dB) and light before theft. In addition to preventing in advance, not only can the intruder know about the intrusion and take action, but it can also prevent other theft by notifying others and the person who is remotely connected with other devices immediately.

In case of power failure, it is powered by internal battery power supply, so it can maintain perfect security function.
