The transmission photoelectric element 62 and the reception photoelectric element 63 are mounted.

The keypad 51 allows the door button 55, the password storage button 56, and the numeric buttons 57 and 58 to be easily adhered to the inside of the glass window having excellent permeability so that the user can easily operate the door button 55, the password storage button 56, and the finger from the outside. When a non-transparent object such as touches each of the buttons 55, 56, 57, 58, the transmission wavelength of the transmission photoelectric element 62 is reflected to be received by the reception photoelectric element 63. 57, 58) to perform the function.

The microprocessor 70 recognizes one switch by measuring the intensity of the frequency and the wavelength received from the keypad 51 and the time reflected from the keypad 51, and compares and judges by a built-in program to determine whether to control. .

The pulse generator 71 generates a wavelength and a frequency of light to distinguish it from sunlight or other disturbing light waves (approx. 40 kHz), and measures the output frequency to measure the output frequency. It serves to send to the microprocessor 70 via).

The photo-receiving waveform detector 72 detects only the wavelength of the light modulated by the pulse generator 71 to shape the waveform, input the microprocessor 70 to count, and detects the weak pulse by amplification. Detects only the standardized wavelength (about 40 kHz) and outputs an input signal to the microprocessor 70.

In addition, one photoelectric wave detection unit 72 is provided for each button 55, 56, 57, and 58 provided in the keypad 51 to be connected to a corresponding port of the microprocessor 70 to operate.

The start transmitting / receiving touch unit 73 has the same structure as that of the buttons 55, 56, 57, 58 of the keypad 51, but is used as a start signal source for continuous power supply to the keypad 51. .

That is, when the switch SW1 is high, the keypad 51 and the photo-receiving waveform detector 72 are in the operation standby state when the buttons 55, 56, 57, 58 of the keypad 51 are touched from the outside. It is supplied to the start power of the power supply), and when each button (55, 56, 57, 58) of the keypad 51 is touched for a predetermined time, it is configured to use as a password number input start signal source.

When the power supply unit 74 does not use the door lock control device 50 of the present invention, the power supply to the keypad 51 and the photoelectric wave type detection unit 72 is cut off, and the power supply of the start transmission and reception touch unit 73 is Leave it unblocked so that when the signal is received by the start transmission / reception touch unit 73, the power of the entire door lock control device 50 is configured to be turned ON.

The door lock control device 50 of the present invention configured as described above is;

The keypad 51 is brought into close contact with a glass window (made of a material having transparency) close to the door, so that each button 55, 56, 57, 58 provided on the keypad 51 from the outside is held like a finger. When the optical frequency of the transmitting photoelectric element 62 of each button 55, 56, 57, 58 is reflected by touching (taking) a transparent object, the receiving photoelectric element 63 receives the photoelectric wave receiving waveform 72. Input to the microprocessor 70 through.

When the microprocessor 70 receives the input frequency and reflects the measured time, the microprocessor 70 recognizes one switch when it matches the program (password) set by the user. You have control over whether

This operation can be performed several times to store an arbitrary number of more than the set number of digits.This password can be stored and stored in YPIROM 75, which can be used by registering a highly advanced password generation program and the corresponding password password, and resetting as necessary. To do it.

In this state, when each button (55, 56, 57, 58) of the keypad 51 provided on the inside of the glass window 100 is touched with a finger or a non-transparent object, the corresponding button (55, 56, 57, 58) The optical frequency of the transmitting photoelectric device 62 is reflected and received by the receiving photoelectric device 63 and transmitted to the microprocessor 70 through the photo-receiving waveform detector 72.

Then, the microprocessor 70 counts this and uses it as one recognition signal to make an encryption code using the configuration of the keypad 51 listed (multiple buttons 55, 56, 57, 58). ) And unlock the door by locking each of the buttons (55, 56, 57, 58) of the keypad (51) to unlock the door or other locking means. .

3 is a flow chart showing a routine for the initial operation and power supply of the door lock control apparatus using the photoelectric device to which the technology of the present invention is applied, and FIG. 4 is a door using the photoelectric device to which the technology of the present invention is applied. Looking at the flow chart showing the signal processing and execution relationship of the lock control device,

First, referring to the seat system check for executing the door lock control device 50 and the standby routine of the microprocessor 70, after checking whether the input of the switch SW1 is High through RD6, the switch When the SW1 is in the high state, the microprocessor 70 cuts off the power through the RC6 and the RC7 to cut off the power of the keypad 51 and the pulse generator 71.

When the output of the switch SW1 is low, the process proceeds to the next step, in order to supply the pulse generator 71 with power, the microprocessor 70 is made high through RC7, and the power supply of the start transmission touch unit 73 is supplied. Microprocessor 70 is also made high through RC7.

Then, the microprocessor 70 transmits the reception state of the start transmission touch unit 73 to the photoelectric wave detection unit 72 to amplify the frequency of the pulse generator 71 through RD5 and store it in the corresponding RAM. Detect and waveform-form only the frequency that has passed the BPF.

In this state, the microprocessor 70 counters the frequency transmitted from the photo-receiving waveform detector 72 through RC5 to determine whether or not it matches the transmission frequency.

Then, the microprocessor 70 checks the oscillation frequency through RD5 and compares the received frequency with the oscillated frequency through RC5.

If it is not matched, it returns to the initial state, and if it is matched, it checks whether the frequency input through RC5 is maintained for the set time, which is recognized as one key when the correct frequency is maintained for a certain time. This is to make it available.

If the check result is not maintained for the set time, it returns to the initial state, and if the oil is set for the set time, the power supply unit 74 is set to the high state through RC6 of the microprocessor 70 to supply the driving current of the keypad 51. Make it.

In this state, the microprocessor 70 checks whether the set frequency is input even at one place through the keypad 51, the photoelectric wave detection unit 72, and the start transmission touch unit 73. In the absence of a key, the microprocessor 70 returns the initial state by switching the power supply 74 to a low state so that the keypad 51 can be powered off through RC6.

If there is a key input as a result of the check, the microprocessor 70 finishes a process by making the power supply unit 74 high through RC6 to supply power to the keypad 51. It goes to the stage of generating, reading and executing an encryption code.

This process is generated by the number of passwords and the user decides whether to save or decrypt the key pressed and to open or close the door.

Referring to FIG. 4, a process for processing a received signal, generating an encryption code, and panning in the above state is as follows.

The microprocessor 70 generates a beep sound through the speaker 77 and presses the key of the start transmission touch unit 73 for a set time for operation. The door is provided in the keypad 51. The signal of the button 55, the password storage button 56, and the numeric buttons 57, 58 is input to shape the waveform through the amplified BPF for the frequency required by the photoelectric waveform detection unit 72.

Then, the microprocessor 70 counters the port with the change and determines whether it matches the frequency band checked by the infrared waveform detection unit 72. Then, the microprocessor 70 determines whether there is a delay for a predetermined time and at the same time, even if a frequency enters the various ports. Each port is rotated in sequence to prevent duplication.

In this state, the microprocessor 70 determines whether the corresponding input port is maintained for the set time from RB0 to RB6 and RC0 to RC5. If not, the microprocessor 70 recognizes it as an error and returns to the beginning for another port check and maintains it. If so, go to the next step.

If it is maintained for a set time, the high and low state of the corresponding port is 40㎑ by the microprocessor 70, and after determining that the frequency is maintained for a certain time, it outputs a beep signal to inform whether the key is recognized and the password number as many times as desired. Remember to store only the current counter and increment the corning in the program.

Then, the microprocessor 70 checks whether the contents of the corresponding port are stored as many times as desired, and if not, returns to the initial state, and if it is stored, prepares the storage position by the set number of digits and receives the door closing key input. Comparison is made with the password number memorized in the Y pyrom 75.

Of course, the registration of the password number, it will be natural that several people can register with different numbers.

In this state, if it is not stored by checking whether the storage key is pressed;

When the open / close key is pressed and the password matches, the microprocessor 70 operates the door relay 76 according to the intention to perform the touch switch flip-flop operation for opening and closing the door. ) So that you can start by generating a beep to the speaker (77).

When the open / close key is pressed but the passwords do not match, the microprocessor 70 generates a beep sound through the speaker 77.

When the storage key is stored in the state of being compared with the password number stored in the easy python 75, the stored key can be started by storing the set password in the easy pyro 75.

The present invention by pressing each button (55, 56, 57, 58) on the keypad 51 visible through the glass window to enter the preset password number by the microprocessor 70 checks this door relay 76 connected to the door lock ) So that the door can be toggled on and off.

Of course, when the microprocessor 70 is used in connection with other control means in addition to the door relay 76, it will be obvious that it is possible to control the lock and release of the door as well as other devices.

The present invention as described above is a reflection object such as a finger on the outside of the glass window after the transmission and reception unit made of a photoelectric element such as an infrared LED (LED) is located on the inner side of the glass window of the side of the home or office or the glass window of the car By recognizing the frequency coming back by using a single key and then combining it to create a password, if the password is matched, it can easily control the door or various devices from the outside, which can contribute to the convenience of users. Can be.
