Referring to fig. 1, the smart home security control system of the present embodiment includes a micro control unit 10, a detection module 20, and an anti-pinch mechanism 30.

The detection module 20 may be a device or a product that can detect whether an identification object passes through or approaches, including but not limited to an infrared sensor, a correlation or reflection type photoelectric sensor, and the like. The detection module 20 is communicably connected to the micro control unit 10 and transmits the signal detected by the detection module to the micro control unit 10.

In the present invention, the micro control unit 10 may adopt a minimum system of a single chip, or an existing product with operation and control functions such as PLC. The detection module 20 is an existing product, a data terminal of the detection module is usually connected with an I/O interface of the micro control unit 10, and specific wiring of different products may be different, and may be adaptively adjusted according to the description of the corresponding product, so specific wiring details are not described herein again.

The anti-pinch mechanism 30 includes an electromagnetic anti-pinch lock 32 provided on a door frame and a detection device 31 for detecting a position of the door or an open/close state of the door.

The electromagnetic anti-pinch lock 32 is provided with a locking pin (not shown) which can be extended or retracted when the power is switched on or off, for example. The electromagnetic anti-pinch lock 32 is also a conventional product, and other specific structures of the electromagnetic anti-pinch lock are not limited in the utility model, so that the electromagnetic anti-pinch lock is not described in detail.

Like the detection module 20, the data terminal of the detection device 31 is also connected to the I/O interface of the mcu 10 to receive the detection signal. The detecting device 31 may be a sensor for collecting a distance, and may determine the open/close state of the door according to the distance in the field, or may be a sensor for collecting an angle, and may determine the open/close state of the door according to the angle of the door, or may determine the open/close state of the door by using other types of sensors, which is not limited in the present invention.

If the current door is in the open state, the door may be suddenly closed, and if it is determined that the distance between the person and the door is within a certain range according to the signal of the detection module 20, the micro control unit 10 controls the lock pin of the electromagnetic anti-pinch lock to extend out, so that the lock pin can be blocked between the door and the door frame, and accidents such as pinch injury caused by closing the door are prevented.

If the current door is already in the closed state, no accident situation occurs.

When determining whether the distance between the person and the door is within a certain range, the configuration may be performed according to the corresponding detection module 20, for example, an applicable detection distance is selected. The range itself may be adapted as desired, and the utility model is not particularly limited or restricted thereto.

If it is determined that the person is out of the range, the mcu 10 controls the pin of the electromagnetic anti-pinch lock to retract to allow the door to be closed.

Preferably, the anti-pinch mechanism 30 further includes a door closer (not shown) for mounting on the door. The door closer has a damping effect, can prevent the door from being closed suddenly and quickly, can prevent clamping injury and can avoid impact caused by sudden closing. Preferably, the door closer can adopt a built-in anti-pinch door closer disclosed in CN111441681A, for example, to further improve safety.
