smart key handle

Abstract

The invention belongs to the field of single-chip microcomputer and sensor technologies and provides an intelligent key handle. The intelligent key handle of the present invention comprises a touch switch, a single-chip microcomputer, a single-axis gyroscope, a real-time clock module, a power source module and a display screen; the touch switch is connected with the single-chip microcomputer, andis used for sending external wakeup signals to the single-chip microcomputer; the ADC interface of the single-chip microcomputer is connected with the single-axis gyroscope, so that the single-chip microcomputer can be used for identifying a door locking action according to the detection signals of the single-axis gyroscope after receiving the external wake-up signals; the real-time clock module is connected with the single-chip microcomputer and is used for performing timing and providing door locking time to the single-chip microcomputer; the power source module is used for supplying power to other components; and the display screen is connected with a display output end of the single-chip microcomputer and is used for displaying the door locking time. The intelligent key handle of the invention can identify the locking door action and record the door locking time. According to the intelligent key hand, a key just needs to be modified slightly, so that the re-making of the key is notrequired; and deployment and application are simple.

Description

technical field [0001] The invention relates to the technical field of single-chip microcomputers and sensors, in particular to an intelligent key handle. Background technique [0002] In daily life, for many middle-aged and elderly people and mental workers, there is often a situation of inattentiveness when leaving the room to lock the door, which makes them doubt whether the door has been locked after leaving the room for a period of time, causing them to have to return Inspections waste time, energy and resources. The existing technology available to solve this problem is smart door locks, and some smart door locks can remind users to lock the door with an alarm or other means when the user leaves. Smart door locks can remind users to lock the door, but the installation of smart door locks requires the replacement of door locks, which is difficult to deploy, and the cost is relatively high, so it is not easy to be accepted by middle-aged and elderly people who really ne...

Problems solved by technology

Smart door locks can remind users to lock the door, but the installation of smart door locks requires the replacement of door locks, which is difficult to deploy, and the cost is relatively high, so it is not easy to be accepted by middle-aged and elderly people who really need it

[0003] The published patent application No. 201610292856.X (publication No. CN105971399A) discloses a smart key based on a photoelectric sensor. The smart key is mainly based on a photoelectric sensor. The user's lock time is to achieve the purpose that the user can confirm whether the door has been locked at a specific time, and the smart key needs the user to replace a new key, and cannot be directly installed on the existing key

The patent application whose application number is 201120188133.8 (publication number is CN202227786U) discloses a kind of key with the prompt function of locking the door. Although it can prompt the time of locking the door, the application uses the trigger key to detect the key rod connector to record the time, and the accuracy Not high, at the same time, the invention makes relatively complicated modifications to the mechanical structure of the key itself, and also requires the user to replace a new key
