Detailed ways

Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:

A new type of multifunctional electronic password door lock is composed of a door lock host and a remote controller. The door lock host includes a door inner shell, a door outer shell, an electronic lock body and a host control circuit. As shown in Figure 1, the door inner shell The body is provided with a display screen and a keypad inside the door, which are connected with the control circuit of the host; Connection; as shown in Figure 3, the host control circuit includes a backup power supply, a single-chip microcomputer, a display module, a button circuit, a wireless communication module, a short message sending module, a motor drive module, a voice input module, a sound output module, an abnormal door opening and an abnormal detection module , the backup power supply adopts the battery power supply mode to supply power for the control circuit, and the single-chip microcomputer communicates with the display module, button circuit, wireless communication module, SMS sending module, motor drive module, voice input module, sound output module, abnormal door opening and The abnormal detection module is connected, the motor drive module is connected with the electronic lock body, and the motor drive module realizes unlocking and locking functions under the control of the single-chip microcomputer. The novel multifunctional electronic password door lock can not only be operated with a keyboard, but also can be operated with a remote controller. As shown in Figure 4, the remote controller includes a There are remote control buttons on the casing, and the remote control buttons are connected with the remote control control circuit. The remote control control circuit includes a microprocessor, a sound output module, a key circuit, and a wireless communication module. The microprocessor passes through the I/O interface. It is connected with the sound output module, the button circuit and the wireless communication module to realize the remote control function of the door lock.

The host control circuit uses the single-chip microcomputer as the control core to control the entire working process. The single-chip microcomputer is connected with the keyboard inside the door and the keyboard outside the door which are arranged on the inner shell of the door and the outer shell of the door through the key circuit. in:

The keypad inside the door includes number keys, listening to the voice key, OK key, cancel key, password modification key, time modification key, door opening key, etc. to realize functions such as password modification, time modification, listening to voice messages, opening the door, closing the external keyboard or remote control, etc. , the whole operation process is controlled by the single-chip microcomputer to control the sound output module to make a sound, so as to realize the voice prompt function. When the key to listen to the voice is pressed, the single-chip microcomputer reads the recorded message from the memory and plays it through the sound output module.

The keypad outside the door includes number keys, message start key, message end key, etc. to realize the functions of password input, start message and end message. When the user enters the correct password, the door lock will automatically open; when the password is entered incorrectly for 3 times, the MCU will automatically send a text message to the designated user through the text message sending module. At this time, the unlocking function of the keyboard outside the door will be temporarily closed. After the device opens the door and resets the password on the keypad inside the door, the unlocking function of the keypad outside the door can resume normal operation. The keypad unlocking function outside the door can also be set to off, and only the remote control is used to unlock. In addition, the voice message function can be realized through the message start and message end buttons. When the message function is realized, the single-chip microcomputer controls the voice input module to record and store the sound. The single-chip microcomputer controls the display screen on the inner housing of the door through the display module to display prompt menus, input information, time and date and other information.

The remote control uses the microprocessor as the control core to realize the remote control function of the door lock. The remote control casing is provided with remote control keys including number keys, confirmation keys, modification keys, and door lock keys to realize functions such as unlocking and locking. After the user enters the correct password, press the confirmation button and the door lock will automatically open. If there is no operation for a period of time, the door lock will automatically lock. If the user is not at ease, he can press the lock button to manually lock the door. Press the modifier key to change the password. If the password is entered incorrectly for 3 times, the remote unlocking function will be temporarily disabled, and a text message will be sent to the designated mobile phone. The remote unlocking function can only be restarted after the door is unlocked by the keyboard outside the door. The remote unlock function can also be turned off by the keypad inside the door. When the remote controller control circuit performs remote control on the door lock, it transmits data through the wireless communication module, and the wireless communication module is realized by using an infrared sending and receiving device. When the battery power inside the remote controller is too low, the sound output module will alarm and prompt to replace the battery.

In order to save power in the utility model, the single-chip microcomputer in the host control circuit is in a standby state at ordinary times. When a key is pressed, the single-chip microcomputer calls the corresponding subroutine according to the corresponding key; when a key is pressed on the remote controller, the remote control It will send information to the single-chip microcomputer, apply for an interrupt to the single-chip microcomputer, and the single-chip microcomputer will respond to the interruption, that is, enter the identification process of the key, and then execute the corresponding program for processing.

It should be emphasized that the embodiments described in the utility model are illustrative rather than restrictive, so the utility model is not limited to the embodiments described in the specific implementation, anyone skilled in the art according to the utility model Other implementations derived from the technical solution also belong to the protection scope of the present utility model.
