Abstract

An intelligent reminding system for a key not pulled out has the functions of detecting the time when the key is inserted in a lock, reminding through ringtone and informing a security office through telecommunication. The system is mainly composed of a keyhole inductor (5), a single-chip microcomputer (3), an APC220 module (2) and a wireless door bell (6). The single-chip microcomputer (3), the APC220 module (2) and the wireless door bell (6) are mounted in a door (1), and the keyhole inductor (5) is mounted on a torsion spring portion inside a door lock (4). The keyhole inductor (5) is connected with the single-chip microcomputer (3). The single-chip microcomputer (3) is connected with the APC220 module (2), and the single-chip microcomputer (3) is connected with the wireless door bell (6) in a wireless mode. The keyhole inductor is combined by a Hall element and a magnet, and detects whether the key is inserted into a key hole or not according to whether a Hall effect is generated. The Hall element and the magnet are mounted on the torsion spring portion inside the door lock. When the key is inserted into the door lock and is turned, the torsion spring is contacted with the magnet, the Hall effect is generated, the Hall element detects inserting of the key and sends a signal for requesting to start timing to the single-chip microcomputer, and the single-chip microcomputer starts timing. When the timing reaches a set time, the single-chip microcomputer sends singles to the door bell, and the wireless door bell gives alarm. If the key is still left on the door lock after a period of time, the single-chip microcomputer sends signals to a wireless communication module, and the wireless communication module is made to send signals to the security office.

Description

Key does not pull out the intelligent reminding system

Technical field

The utility model relates to forgets the system of extracting after a kind of indicating reminders key inserts door lock, has the key of detection and enters to lock the function that Security Department is informed in time function, doorbell the tinkle of bells prompt facility and telecommunication.

Background technology

In the modern life, the application of security door is very extensive.But in the face of heavy life stress, user's switch door lock is taken away or is copied by other people such as key by often key being retained on the door lock, with serious harm family and individual's personal safety as well as the property safety.For above deficiency, inventing a kind of effective key, not pull out the intelligent reminding system very necessary.

Summary of the invention

Do not possess the function that prompting user is extracted key in order to overcome existing door lock, the utility model provides a kind of key not pull out the intelligent reminding system, this system has the key of detection and enters to lock the function that Security Department is informed in time function, the tinkle of bells prompt facility and telecommunication, guarantee owner forget extract key after in the short time key taken away by owner or the staff of Security Department, effectively avoid key loss to cause the generation of the harm such as financial losses.

The technical scheme that its technical problem that solves the utility model adopts is: this system is mainly connected to form by lockhole inductor, single-chip microcomputer, APC220 module and wireless doorbell.Single-chip microcomputer, APC220 module and wireless doorbell are installed in door, the lockhole inductor are installed in the torsion spring place of door lock inside.The lockhole inductor is connected with single-chip microcomputer, and single-chip microcomputer is connected with the APC220 module, and single-chip microcomputer is connected by wireless with wireless doorbell.

In the time of after inserting key turns, the lockhole inductor detects key and inserts, and sends to single-chip microcomputer and requires the beginning timing signal, and single-chip microcomputer begins timing.To the fixed time, single-chip microcomputer sends signal to doorbell until timing, and doorbell gives the alarm.As over time, key also is retained on the door lock, and then single-chip microcomputer is by the APC220 module Security Department signal that gives the alarm.

The utility model simple in structure and low in cost, easy to use, have the key of detection and enter to lock the function that Security Department is informed in time function, the tinkle of bells prompt facility and telecommunication, guarantee owner forget extract key after in the short time key taken away by owner or the staff of Security Department, effectively avoid key loss to cause the generation of the harm such as financial losses.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model scheme of installation.

Among the figure: 1. 2. APC220 modules, 3. single-chip microcomputers, 4. door locks, 5. lockhole inductors, 6. wireless doorbell

The specific embodiment

As shown in Figure 1, system is mainly connected to form by lockhole inductor (5), single-chip microcomputer (3), APC220 module (2) and wireless doorbell (6).Single-chip microcomputer (3), APC220 module (2) and wireless doorbell (6) are installed in door (1), and lockhole inductor (5) is installed in the inner torsion spring place of door lock (4).Lockhole inductor (5) is connected with single-chip microcomputer (3).Single-chip microcomputer (3) is connected with APC220 module (2), and single-chip microcomputer (3) is connected by wireless with wireless doorbell (6).

Whether the lockhole inductor is the combination of Hall element and magnet, detect and have key to insert according to whether Hall effect occurs.Hall element and magnet are installed in the torsion spring place of door lock inside.In the time of after key inserts the door lock rotation, torsion spring contacts with magnet, and Hall effect occurs, and Hall element detects key and inserts, and sends to single-chip microcomputer to require to begin timing signal, and single-chip microcomputer begins timing.To the fixed time, single-chip microcomputer sends signal to doorbell until timing, and doorbell gives the alarm.As over time, key also is retained on the door lock, and then single-chip microcomputer sends signal to wireless communication module, makes wireless communication module send signal to Security Department.
