Optical communication lock body based on Internet of things

Abstract

The invention relates to an optical communication lock body based on the Internet of things. The lock body comprises nineteen parts including a control module, a door lock execution module, a light receiving module, a matrix keyboard module, a USB female base communication module, a WiFi module, a display module, an acousto-optic prompt module, a battery detection module, a key sensing module, a power management module, a wireless power supply transmission module 0, a wireless power supply transmission module 1, a DC power module, a power switching module, a wireless power supply receiving module, a charging module, a battery interface and a standby battery and the like. When working, the optical communication lock body keeps connection with the cloud side all the time. After the key is inserted, the wireless power supply transmission modules are driven to work; data sent by the key are received and the received data are decoded; the decoded data are compared with key information stored internally; and after successful comparison, unlocking is performed and information transmitted by the key is uploaded to the cloud side for storage, so that unlocking is still performed by the cloud side even when the key is lost or forgotten to bring. The optical communication lock body is mainly applicable to the field of smart homes.

Description

technical field [0001] The invention relates to an optical communication lock body based on the Internet of Things, belonging to the technical field of smart home. Background technique [0002] The traditional mechanical locks currently on the market are easy to copy the key, and the mechanical transmission method used to unlock the lock is easy to be picked by technology. Smart locks such as electronic locks and combination locks are easily interfered by the high-frequency transmitter of the Tesla coil, which makes the chip work unstable, and frequent resets cause the pin level to be unstable and open the door. Fingerprint locks are easy to be stolen by people and lose their protection functions. Some remote control locks have a wide range of radio waves and strong penetrating power during data transmission, and the information is easy to be intercepted and cracked. The traditional lock body only executes the door opening action as long as the key is recognized as authenti...

Smart locks such as electronic locks and combination locks are easily interfered by the high-frequency transmitter of the Tesla coil, which makes the chip work unstable, and frequent resets cause the pin level to be unstable and open the door

Fingerprint locks are easy to be stolen by people and lose their protection functions. Some remote control locks have a wide range of radio waves and strong penetrating power during data transmission, and the information is easy to be intercepted and cracked.

As long as the traditional lock body recognizes the authenticity of the key, it only performs the door opening action. Once the lock body is opened illegally, the operating status of the lock body, the key information when unlocking, and the time of unlocking cannot be known in time and relevant measures can be taken by the user
