- a card reader connected to the password information storage card and reading the password information therefrom and then converted into an electrical pulse signal
- a signal amplifying unit connected to the card reader and amplifying the electrical pulse signal
- the light-emitting unit that is connected to the signal amplifying unit and that is amplified by the signal amplifying unit controls the light-emitting unit that is turned on and off.
- the light emitting unit is an LED light.
- the decoding unit includes:
- a decoder coupled to the photosensitive device and the second cryptographic information storage card, configured to amplify the electrical signal and process the cryptographic information therefrom, and then into the second cryptographic information storage card
- the pre-stored password information is compared, and when it is detected that the parsed password information is the same as the pre-stored password information, the electric lock is controlled to be unlocked.
- the photosensitive device is a photodiode.
- the electric lock includes an electric motor, an electromagnetic relay, and a mechanical lock: the decoding unit detects When the received password information is the same as the pre-stored password information, the motor and the electromagnetic relay are controlled to be activated, and the mechanical lock is opened by the motor to lock the mechanical lock.

- the decoding unit 2 controls the starter motor and the electromagnetic relay when detecting that the received password information is the same as the pre-stored password information, and the lock is opened by the motor driving the latch of the mechanical lock.
- the optical fiber can be used as a transmission carrier for the optical signal.
- the optical fiber passes through the small hole 4 reserved in the door panel, one end is fixed to the outer side of the door panel, and the other end is connected to the decoding unit 2 mounted on the inner side of the door panel.
- the 2 is a structural example of the photoelectric key 1, which is connected to the card reader 12, and the card reader 12 reads from the first password information storage card 11.
- the password information is then converted into an electrical pulse signal, and the signal amplifying unit 13 connected to the card reader 12 amplifies the electrical pulse signal to adapt to the light emitting unit 14
- the performance requirement is that the power pulse signal amplified by the signal amplifying unit 13 controls the power supply of the light-emitting unit 14 to be turned on and off, and the light-emitting unit M is driven to blink, so that the light-emitting unit 14 outputs the password information with or without illumination as a basic feature code.
- the light emitting unit 14 can be implemented by using an LED lamp.
- the decoder 22 simultaneously connects the photosensor 21 and the second password information storage card 23, and the photosensor 21 is located at the inner side of the door panel.
- the position of the hole 4 receives the optical signal from the photoelectric key 1 and is converted into an electrical signal, and the decoder 22 shapes and amplifies the electrical signal and parses the password information therefrom, and then stores the password pre-stored with the second password information storage card 23.
- the information is compared, and when it is detected that the parsed password information is the same as the pre-stored password information, the electric lock 3 is controlled to be unlocked.
- the photosensitive device 21 can employ a photosensitive diode.
- the utility model adds a battery unit (such as a rechargeable battery) and a power-off protection unit to the system, and powers off.
