Description

Technical Field

[0001] The utility model relates to the technical field of door magnetic early warning, in particular to a door magnetic early warning device. Background Art

[0002] The door magnetic warning system is a security alarm system that monitors the opening and closing status of doors or windows to achieve security monitoring of specific areas. The door magnetic warning system consists of two parts: a door magnetic switch and an alarm host. The door magnetic switch consists of a permanent magnet and a reed switch. When the permanent magnet and the reed switch are very close (less than a certain distance, usually 5 mm), the door magnetic sensor is in a working standby state; when the permanent magnet leaves the reed switch at a certain distance, the reed switch will close, causing a short circuit. At this time, the alarm indicator light will light up and send an alarm signal to the alarm host. After receiving the signal, the alarm host will trigger the corresponding alarm action, such as sounding an alarm, dialing a preset phone number, etc. However, the existing door magnetic warning device can only remotely monitor the opening and closing status of doors and windows. When it is detected that the doors and windows are in the open state, the opening and closing of the doors and windows cannot be remotely controlled. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a door magnetic early warning device, which effectively solves the shortcomings of the prior art.

[0004] The purpose of the utility model is achieved through the following technical solutions: a door magnetic early warning device, including a door magnetic fixing plate and a magnetic strip edge, one side of the door magnetic fixing plate is fixedly connected to the door magnetic host, and the other side of the door magnetic fixing plate is fixedly connected to the take-up drum, the internal rotation of the take-up drum is connected to the wire roller, the wire roller is wound with a steel wire rope, and one end of the steel wire rope is assembled and connected to the magnetic strip edge.

[0006] The above technical solution is adopted: by setting a door magnetic host with a signal transmission device on the door magnetic fixing plate, when the door magnetic host is close to the edge of the magnetic stripe, the door magnetic host recognizes the edge of the magnetic stripe and confirms that the door and window are in the closed state; when the edge of the magnetic stripe is away from the door magnetic host, the door magnetic host recognizes that the door and window are in the open state and sends an alarm signal to the control center.

[0015] The utility model has the following advantages:

[0016] 1. The door magnetic early warning device is equipped with a door magnetic host with a signal transmission device on the door magnetic fixing plate. When the door magnetic host is close to the edge of the magnetic strip, the door magnetic host recognizes the edge of the magnetic strip and confirms that the doors and windows are in a closed state. When the edge of the magnetic strip is away from the door magnetic host, the door magnetic host recognizes that the doors and windows are in an open state and sends an alarm signal to the control center. Suction cups and adhesive strips are set on the door side fixing plate and the edge of the magnetic strip, and the two fixing methods are combined to fix them, so that they are installed on the door and window frames and doors and windows respectively, so that the door side fixing plate and the magnetic strip edge are stably installed on the doors and windows for long-term work.

[0017] 2. The door magnetic early warning device is configured to control the extension and retraction of the steel wire rope by arranging a motor-driven wire roller on one side of the door magnetic fixing plate. When the control personnel remotely detect that the doors and windows are in the open state, the wire roller can be controlled to rotate to retract the steel wire rope, thereby remotely closing the doors and windows, thereby realizing remote closing control of the doors and windows equipped with the door magnetic early warning device. By arranging an electric push rod at the center of the wire roller, the extension and retraction state of the electric push rod can be controlled to control whether the output end of the motor is assembled with the wire roller. When the doors and windows need to be opened normally, the electric push rod is in a retracted state, and the motor is not assembled with the wire roller. The doors and windows can be pushed to open them.
