Detailed Description
Referring to fig. 1-2, an externally-hung intelligent identification control door lock comprises a circuit board, a fingerprint sensor 1, a motor 2, and a power module 3 for supplying power to the circuit board, the fingerprint sensor and the motor; the circuit board is connected with a motor, and the motor is connected with the lock cylinder 4. The fingerprint sensor detects fingerprint information and sends the fingerprint information to the circuit board, and the circuit board analyzes the fingerprint information and uploads and compares the fingerprint information; the motor is controlled to start and stop through the circuit board, and the motor is connected with the rotation of the lock cylinder motor to drive the lock cylinder to rotate, so that unlocking is realized. The circuit board comprises a photoelectric conversion module 5, an operation processing module 6 and a communication module 7 which are connected in sequence; the photoelectric conversion module is electrically connected with the fingerprint sensor. Through the photoelectric conversion module, fingerprint information detected by the fingerprint sensor is converted into an electric signal, the electric signal is sent to the operation processing module for data analysis and storage, and the analyzed data is sent to the background DCS control system and the mobile phone APP through the communication module. The power module is used for converting an external power supply to provide a stable power supply for the intelligent identification control door lock as the control door lock is supplied with power by DC 6V; fingerprint sensor: the light is emitted to the prism from the bottom and then reflected to the finger surface, and the light intensity of the reflected light is different from the light intensity of the reflected light due to the fact that the surface of the finger is uneven, and the CMOS optical device can collect picture information with different light intensities; a photoelectric conversion module: the optical signal of the fingerprint sensor is converted into an electrical signal through the optical module, and the signal isolation effect is also achieved; an operation processing module: the digital signal processor comprises a DSP and a storage chip, wherein the DSP compares characteristic parameters in the acquired electric signal with a fingerprint library in the storage chip, obtains whether the authority of opening the control door lock exists or not through logical operation, and transmits the signal to a communication module; a communication module: after receiving the judgment signal of the operation processing module, the communication module converts the signal into an optical signal, and sends the optical signal to the background DCS control system for confirmation; and meanwhile, the signal is sent to a mobile phone of a controller for confirmation through the wireless module.
The lock core is connected with a door lock state indicator light 8. Because the lock core is connected with the lock state indicator lamp, the corresponding lamp of the lock state indicator lamp for opening the lock is convenient for a user to identify.
The operation processing module comprises a DSP, a storage chip and a relay, and the relay is electrically connected with the motor. The DSP compares the characteristic parameters in the acquired electric signals with a fingerprint library in a storage chip, obtains whether the authority of opening the control door lock exists or not through logical operation, and transmits the signals to the communication module; the small relay on the operation processing module is connected with the motor, and when the operation processing module receives an unlocking signal, the small relay is closed, the motor is electrified, and the lock cylinder is driven to be unlocked; the motor is connected with a small relay on the operation processing module, and after the operation processing module receives an unlocking signal, the small relay is attracted, the motor is electrified, and the lock core is driven to be unlocked.
