Description

Intelligent non-contact door lock signal converter

technical field

The present invention relates to an intelligent non-contact door lock signal converter, especially a non-contact detection method, which can actively inform the user that the door panel, window sash or drawer is not closed properly, and can also encode the data of the lock. Real-time transmission/reception of repair and door opening records.

Background technique

Objects such as doors, windows and drawers in daily life will use a lock body as a tool for controlling the closing (LOCK) or unlocking (UNLOCK) of doors, windows and drawers. For example:

In the access control monitoring system, the use of locks is very common and there are many types, generally including: mechanical locks, general electric locks (locks that are directly or indirectly driven by solenoid valves or motor drivers, but the control circuit itself is not installed in the system) Locks) and electronic locks (locks that contain a control circuit board and can be directly or indirectly driven by a motor, solenoid valve or piezoelectric driver, etc. to move the deadbolt), etc.

However, whether it is a general electric lock or an electronic lock (hereinafter referred to as an electric lock), it must provide power to supply the driver when it is in use, and there are roughly two types of such power: one is a battery, and the other is a wire. Connect to an external power source (mains). But both of these have their drawbacks. For example, the problem of forgetting to replace the battery due to power exhaustion, and the problem shown in Figure 1 and Figure 2 will be used if the external power supply (mains power) is used, that is, the electric lock 80 is mainly installed on the openable object 70, the present embodiment takes "door" as an example, so the openable object 70 is a door panel, if it is a "window", the openable object is a window sash, and if it is a "cabinet" then the openable The object is the drawer, so I won’t repeat it here.

Therefore, if the "door" is used as an illustration, the pivoting hinge (hinge) 90 of the door panel 70 must use a wired hinge (hinge) 90 as shown in Figure 2, so that the wires 91 After being introduced by the door frame 60, it is connected to the electric lock 80 through the wired hinge 90 to supply the required power. But look into, the mode of this kind of connection power supply 91 is too loaded down with trivial details, construction trouble; And electric wire 91 is easy to break down because of the opening and closing of door often turns around, has reduced the service life or increases the perplexity on the maintenance.

Furthermore, most of the existing door panels, window sashes or drawers cannot actively provide warning signals when they are not closed properly. Even those equipped with detection devices have also adopted contact detection methods, such as detection components such as micro switches; but These contact detection signals must be transmitted back to the host or system control room through a wired hinge. This wired hinge must be difficult to pass through more wires to meet the requirements. If three sets of signals are independent, nine additional wires may be required. line, plus the power line, there are 11 lines, so the lack is as mentioned above, and there will be more room for improvement.
