The present invention allows the user to open or close the lock connected to the wireless receiver installed inside the door by the user inputting the password directly through the password input plate and the button input of the wireless transmitter. It is configured to.

First, since the locking device using the wireless transmission and the receiver does not require a key opening to the outside of the door, any position inside the door can be installed.

In order to be able to enter a password into the wireless transmitter and receiver, the microprocessor presses the password input panel and the microprocessor receives the signal from the password input panel and stores it in non-volatile memory, such as flash memory or EEPROM. .

The user enters the same password into the wireless transmitter and the wireless receiver in a nonvolatile memory inside the microprocessor, and compares the signal sent from the wireless transmitter with the value stored in the wireless receiver when the wireless receiver receives the signal. If this matches, the relay is activated to open or close the lock.

Also, in order to prevent unauthorized opening of the lock device by changing the password of the radio transmitter, the receiving microprocessor compares the signal sent from the radio transmitter with the password stored in the radio receiver to detect the wrong number of times consecutively. After calculating the number 5, the signal from the radio transmitter is ignored for 30 minutes, the radio receiver is stopped and only the time counting is performed.

After 30 minutes, the radio receiver changes to the standby state to receive the value sent by the radio transmitter and compares the value sent by the radio transmitter with the password that the user enters and stores in the radio receiver. .

Hereinafter, with reference to the drawings in order to show an embodiment of the present invention will be described in detail.

1 is a password input plate for allowing a user to directly enter a password into a wireless transmission and receiver. When the start button of 1 in FIG. 1 is pressed, a password is input to the microprocessor (4 in FIG. 2 or 15 in FIG. 3). In the microprocessor (Fig. 2 4 or 15 in Fig. 3), the microprocessor (4 in Fig. 2 or 15 in Fig. 3) is pressed as the number button after the start button (1 in Fig. 1) is pressed. To nonvolatile memory.

When the end button of 2 in FIG. 1 is pressed, it is a signal informing the microprocessor (4 in FIG. 2 or 15 in FIG. 3) that the input of the password is finished.

You can add a password by continuing to press the Start button (1 in Figure 1), the Number button, and the End button (2 in Figure 1).

For example, if the data storage capacity of the non-volatile memory in the microprocessor (4 in Fig. 2 or 15 in Fig. 3) is 64 bytes, if 16 decimal numbers are limited to one password, 16 passwords are inputted. can do.

In addition, if another password is input after the first password is entered, the address where the first password is stored is moved to another address along with the password value, and the latest password is stored in the address. Use

The number of passwords that can be entered is limited by the capacity of the nonvolatile memory in the microprocessor (4 in FIG. 2 or 15 in FIG. 3), but a large amount of nonvolatile memory can be stored in the microprocessor (4 in FIG. 2 or 15 in FIG. Capacity limitation can be overcome because it can be mounted externally.

2 is a transmission processing unit of a wireless transmitter capable of inputting a password, 3 in FIG. 2 is a button input unit, and a transmitting microprocessor (4 in FIG. 2) built in the wireless transmitter is a button input of a user (3 in FIG. 2). ), A transmission ID is generated (6 in FIG. 2) by a password previously inputted by the user through a password input (5 in FIG. 2) in advance.

The generated transmission ID performs signal synthesis (8 in FIG. 2) with the carrier generated by the carrier generation unit (7 in FIG. 2), and finally the infrared light emitting unit (10 in FIG. 2) through signal amplification (9 in FIG. 2). Infrared light is emitted by the light emitting diode (Diode) inside.

As a result, the transmission ID of the radio transmitter is transmitted to the infrared sensor of the radio receiver.

In the present invention, an example of a wireless transmission and reception method is a method using an infrared sensor. However, the present invention is not limited thereto, and the RF transmission and reception method is also included in the present invention.

In other words, in the RF method, a signal is transmitted through an antenna instead of a light emitting diode in a wireless transmitter, and a wireless receiver receives a signal transmitted from a wireless transmitter through an antenna instead of an infrared sensor.

3 is a reception processing unit of a wireless receiver capable of inputting a password, and the transmission ID entered into the infrared reception sensor (11 in FIG. 3) of the infrared reception unit is a band pass filter (12 in FIG. 3) corresponding to the carrier of the wireless transmitter. The weak transmit ID is pulled up through the amplifier (13 in Fig. 3) to a certain signal level, and is detected by the receiving microprocessor (15 in Fig. 3) by the TTL level converter (14 in Fig. 3). Convert to + 5V level. The receiving microprocessor (15 in FIG. 3) stores the password inputted by the user in advance in the non-volatile memory inside the microprocessor through the password input in FIG. 3 of 17) is controlled to open or close the locking device (18 in Fig. 3).
