The first frequency receiver 11 receives a remote controller unique number inquiry transmitted wirelessly from the first frequency transmitter 21 of the wireless controller 2.

The MPU 10 operates in a normal state in a sleep state when a remote control-specific inquiry number is received from the wireless controller 2 through the first frequency receiver 11 to analyze an input signal of a remote controller-specific inquiry signal. Compared to the data value stored in advance in), if it is wrong and ignored, the third power control unit 16 is driven, and the remote controller unique number and door opening data are output to the second frequency transmitter 15.

In addition, when the door open switch SW of the remote controller 1 is artificially pressed, the MPU 10 drives the third power control unit 16 and the fourth power control unit 17 to remove the remote control unique number and the door open data. Output to the two-frequency transmitter 15.

The second frequency transmitter 15 wirelessly transmits the remote controller unique number and the door open data output from the MPU 10 through the amplifier 18 and the antenna 19.

In addition, the MPU 10 may drive the second frequency transmitter 15 by analyzing and inquiring a unique inquiry number transmitted from the plurality of first frequency transmitters 21 through the first frequency receiver 11. .

At this time, when a plurality of remote controllers 1 simultaneously drive the second frequency transmitter 15 to transmit unique remote control numbers and door open data at the same time, there may be a radio frequency collision, so the MPU 10 of the remote controller 1 If the inquiry number unique to the remote controller input through the first frequency receiver 11 is the same as a signal previously input to the MPU 10 memory 13, an irregular random number is generated to control the control start time of the third power controller 16. By controlling with a time difference, it is possible to eliminate the possibility of radio frequency collision by the plurality of remote controller (1).

Output to (21).

In addition, the auxiliary MPU 20 turns on / off the second power control unit 27 periodically.

That is, when the second power control unit 27 is turned on, power is supplied to the second frequency receiving unit 25 and the received data is input to the auxiliary MPU 20, so that the auxiliary MPU 20 is a remote controller previously input to the memory 26. When the identification number and the door opening data are compared and correct, the second frequency data analysis result is transmitted to the digital door lock (not shown) through the external input / output terminal to transmit the external output door opening data.

At this time, the auxiliary MPU 20 periodically turning on / off the second power control unit 27 maintains the ON state until the analysis of the remote controller identification number and the door opening data wirelessly transmitted from the second frequency transmitter 15 is completed. After completion of analysis, turn it ON / OFF periodically for a certain time.

The first power control unit 23 and the second power control unit 27 is controlled by the auxiliary MPU 20, so that the wireless control unit 2 uses a battery or a battery, so as to minimize the power consumption to the first frequency The power supplied to the transmitter 21 and the second frequency receiver 25 is controlled to be supplied at a necessary time.

The second frequency receiver 25 receives the remote controller unique number and the door opening data transmitted from the second frequency transmitter 15 of the remote controller 1 through the antenna 28 and supplies them to the auxiliary MPU 20.

In addition, since there may be a radio frequency collision by a plurality of remote controllers in the wireless controller 2, the auxiliary MPU 20 is wireless when the remote controller unique number and the door open data are received through the second frequency receiver 25. When it is difficult to determine due to frequency collision, the first remote controller unique number is wirelessly transmitted through the first frequency transmitter 21 according to a predetermined order of a plurality of remote controller unique numbers previously input to the memory 26, and the MPC of the remote controller 1 10, after analyzing the unique number of the remote controller through the first frequency receiving unit 11 and transmits a radio frequency through the second frequency transmitting unit 15 if the same as its own unique number stored in the memory, the second frequency receiving unit ( The secondary MPU 20 of the wireless control unit 2 having received the radio frequency through 25) analyzes the result and compares it with the remote controller unique number previously input to the memory 26 to determine the external output, that is, digital output. Outputs a door open signal to the door lock, and outputs the first frequency transmitter 21, a second identification number is incorrect.

Since the above operation is repeatedly performed sequentially, radio frequency collision in the radio controller 2 can be avoided.

2 and 3 are flowcharts illustrating a process of controlling the opening of the digital door lock by operating a specific switch of the remote control or the door lock outside the door.

First, in the case of the wireless control unit 2, the digital door lock uses a battery or a battery, so that the power supplied to the first frequency transmitter 21 and the second frequency receiver 25 may be supplied at a necessary time to minimize battery or battery consumption. To control.

When command data for transmitting the first frequency transmission to the external input is input (S31) (S32) due to a specific switch or the like, the auxiliary MPU 20 drives the first power control unit 23 (S33) to the memory. The first remote controller 21 and the antenna 22 wirelessly transmit the input remote controller unique number inquiry signal (S34).

When the inquiry signal unique to the wireless remote controller is input to the interrupt terminal of the MPU 10 via the first frequency receiving unit 11 of the remote controller 1, the MPU 10 operates in a normal state in a sleep state and is inputted. (S23) compares the data value previously stored in the memory 13 and ignores it if it is wrong and if it is the same, the third power control unit 16 is driven (S26) to supply power to the second frequency transmitter 15, The remote controller unique number and the door opening data are input to the second frequency transmitter 15 to wirelessly transmit through the antenna 19 (S28). At this time, the fourth power control unit 17 is not driven.

The signal transmitted from the second frequency transmitter 15 is input through the antenna 28 of the second frequency receiver 25 and input to the auxiliary MPU 20. At this time, the auxiliary MPU 20 turns on / off the second power control unit 27 periodically. When the second power control unit 27 is turned on (S36), since power is supplied to the second frequency receiving unit 25 and data is input to the auxiliary MPU 20, the auxiliary MPU 20 is previously input to the memory 26. When the remote control unique number and the door opening data are compared (S37) and correct (S38), the external door opening data is transmitted to the digital door lock (S39). At this time, the auxiliary MPU 20 periodically turning on / off is turned on until the analysis of the signal transmitted from the second frequency transmitter 15 is completed, and turns on / off again periodically for a predetermined time after the analysis.

In addition, when the door open switch SW of the remote controller 1 is pressed (S24), the MPU 10 receives the door open data, drives the third power control unit 16, and simultaneously operates the fourth power control unit 17. After driving, the remote controller unique number and the door opening data are output to the second frequency transmitter 15, where the radio signal is amplified by the amplifier 18 and wirelessly emitted through the antenna 19.

In the case of the remote controller 1, the MPU 10 receiving the signals of the plurality of first frequency transmitters 21 through the first frequency receiver 11 may analyze the input signal to drive the second frequency transmitter 15. . At this time, when the plurality of remote controllers 1 simultaneously drive the second frequency transmitter 15 to wirelessly transmit each remote controller unique number and door open data simultaneously, the remote controller MPU 10 may have a first frequency. If the data input through the receiver 11 is the same as the signal previously input to the memory 13 of the MPU 10, an irregular random number is generated to control the start time of the third power supply controller 16 at a time difference to control the number of times. Eliminates the possibility of radio frequency collision by the remote controller (1).

In addition, since there may be a radio frequency collision by the plurality of remote controllers 1 in the radio controller 2, the secondary MPU 20 may be damaged due to radio frequency collision of data input through the second frequency receiver 25. When it is difficult to determine, the auxiliary MPU 20 inputs the first unique number to the first frequency transmitter 21 according to a predetermined order of the plurality of remote controllers previously input to the memory 26 and transmits the radio frequency together with the radio frequency. After receiving and analyzing the MPU 10 through the first frequency receiving unit 11 of the remote controller 1, the radio frequency is transmitted through the second frequency transmitting unit 15.

In addition, when a signal is input through the second frequency receiver 25 of the wireless controller 2, the auxiliary MPU 20 analyzes the input signal and compares and analyzes the input signal with the unique number previously input to the memory 26. If the door open data is output to the digital door lock, the second unique number is outputted.

Since the above operation is repeatedly performed sequentially, radio frequency collision in the radio controller 2 can be avoided.
