Embodiment Construction

[0015] According to the intelligent door lock shown in Figure 1, it is mainly composed of a display, a power supply, a control circuit, a keyboard, an execution part, and a sensor circuit.

[0016] The control circuit is mainly composed of a mobile phone module, a microprocessor, an interface circuit, and a flash memory. The mobile phone module includes a radio frequency circuit, a SIM card interface circuit, etc., and a CPU. High-frequency amplification, receiving local oscillator, frequency mixing, transmitting local oscillator, power amplifier control, power amplifier and other small circuits. The microprocessor adopts single-chip microcomputer, which is 8051 series, 89C, AT89C2051 and other series single-chip microcomputers. Its main function is to exchange data and control the normal operation of each part.

[0017] The power supply is an AC-to-DC regulated power supply, which is always connected in parallel with a rechargeable lithium battery to prevent the door from be...

Description

technical field [0001] The invention relates to a door lock, in particular to an intelligent door lock. Background technique [0002] Now, there are many door locks for anti-theft, such as tumbler locks, magnetic locks, and electronic locks. The most common is a pin mechanical lock. Several pins of different heights are arranged in the lock cylinder, which can be opened with a key of a corresponding shape. Because the number of marbles is limited and the height and position are limited, it is easier to open with some unlocking tools, such as hooks; at the same time, once the key is lost or used, it is easy to be copied, and the only solution is to replace the door lock. The principle of the magnetic lock is similar to that of the tumbler lock, except that several magnetic columns arranged in specific magnetic poles are used instead of the tumbler. With the development of electronic technology, electronic locks have also developed many varieties, such as IC card locks, digi...
