Description

Access control magnetic spring device

This creation is related to condition monitoring and data reporting devices, especially an access control reed device.

Consider an occasion where the status of a certain device needs to be monitored, such as whether the doors and windows are actually closed, usually by regular inspections by personnel. However, this method consumes high personnel costs and may cause errors due to negligence.

Another known method is to use a magnetic reed switch to monitor. When the door and window are not closed, the two reeds in the magnetic reed switch will not be contacted by magnetism, which will cause the circuit to fail. Know the status of doors and windows. The advantages of the magnetic reed switch are that it can automatically monitor the monitored device and obtain monitoring information in real time. Only the power needs to be provided to produce the monitoring effect. If the battery is used as the power source, it will face insufficient battery life and cannot be used for a long time.

In view of this, how to improve the above problems is the most important issue to be solved by the author.

The main purpose of this creation is to provide an access control magnetic reed device that uses passive radio frequency identification technology to accurately monitor whether a door or window is actually closed. Personnel can actively use a reader to obtain monitoring information to achieve management without using electricity. efficacy.

In order to achieve the aforementioned purpose, the present invention provides an access control magnetic reed device, which includes:
A magnet on a movable door or window;
An induction module is arranged on a frame corresponding to the door or window. The induction module includes a vacuum-sealed tube, and two iron pieces that are not in contact under normal conditions are arranged in the inside, and each iron piece is connected to an extension. Out the wires of the vacuum-sealed tube; when the door or window is actually closed on the frame, the magnet is close to the induction module, and the two iron pieces are attracted and contacted by magnetic force;
A monitoring chip is disposed on the frame and is electrically connected to two wires. An antenna coil is electrically connected to the periphery of the monitoring chip, which is used to receive external electromagnetic waves to generate electricity, and then drives the monitoring chip to be sealed in accordance with the vacuum. The contact state of the two iron pieces in the tube generates an electrical signal, and the monitoring chip outputs the electrical signal to the outside.

And the above-mentioned purpose and advantages of this creation can be easily understood from the detailed description and accompanying drawings of the selected embodiments below.

Please refer to FIG. 1 to FIG. 4. The one shown is the access control magnetic reed device provided for this creation, which includes a magnet 1, an induction module 2 and a monitoring chip 3. The magnet 1 is disposed on a movable door or window 4, and the sensor module 2 and the monitoring chip 3 are disposed on a frame 5, wherein the door or window 4 is pivotally disposed on the frame 5 and can be pivoted. Swing to open or close. When the door or window 4 forms a closed state on the frame 5, the magnet 1 is close to and adjacent to the induction module 2.

The above-mentioned induction module 2 includes a vacuum-sealed tube 21, and the inside thereof can be evacuated or filled with an inert gas. Inside the vacuum-sealed tube 21, two iron plates 22 are further provided. The two iron plates 22 are separated from each other and do not contact each other under normal conditions, and each of the iron plates 22 is connected to a wire 23 respectively. Two wires 23 extend out of the vacuum-sealed tube 21 and are electrically connected to the monitoring chip 3. When the door or window 4 is in a closed state on the frame 5, the magnet 1 is close to the induction module 2, and the two iron pieces 22 will be attracted to each other due to the influence of the magnetic force, and then come into close contact with each other; and when When the door or window 4 leaves the frame 5, the magnet 1 moves away from the induction module 2, the two iron plates 22 lose the magnetic force, and return to a position separated from each other without contact.

The monitoring chip 3 is located at an appropriate position on the frame 5. An antenna coil 31 is electrically connected to the periphery of the monitoring chip 3. The antenna chip 31 can receive external electromagnetic waves to generate power, and then drive the monitoring chip 3. After the monitoring chip 3 is driven, an electric signal is generated, wherein the electric signal contains information on whether the two iron pieces 22 in the vacuum-sealed tube 21 are in contact. Then, the monitoring chip 3 outputs the electrical signal through the antenna coil 31 again.

With the above structure, when this creation is actually used, as shown in Figs. 1 and 2, when the door or window 4 is not closed on the frame 5, the magnet 1 is far away from the induction module 2. The magnetic force cannot act on the two iron plates 22, and the two iron plates 22 are separated from each other. When a person uses the reader 8 to emit an electromagnetic wave, the antenna coil 31 generates electricity after receiving the electromagnetic wave, and then drives the monitoring chip 3 to generate an electric signal. At this time, the electric signal will be embedded with "two iron plates 22 separated from each other" The signal is converted into electromagnetic waves through the antenna coil 31 and transmitted back to the reader 8. Then, the personnel can know the state that the door or window 4 is not closed on the frame 5.

Conversely, as shown in Figures 3 and 4, when the door or window 4 is closed on the frame 5, the magnet 1 is close to the induction module 2, and its magnetic force can attract the two iron plates 22 to each other. And close contact. When the reader uses the reader 8, the electric signal generated by the monitoring chip 3 will be embedded with the message "two iron plates 22 are in close contact" and transmitted back to the reader 8, then the personnel can know the door Or the state where the window 4 is actually closed on the frame 5.

Through the above description, we can understand that this creative department uses passive radio frequency identification technology to monitor doors and windows 4, and can monitor whether the windows and doors 4 are tightly closed without the need to set up a power supply. People only need to operate when they need to know the status of doors and windows The reader can obtain the information immediately and clearly, and can achieve the effect of no energy consumption and continuous monitoring.

However, the disclosure of the above embodiments is only used to explain the creation, not to limit the creation. Therefore, the replacement of equivalent components should still belong to the scope of the creation.

In summary, those skilled in the art can understand that this creation can indeed achieve the aforementioned purpose, and it has indeed complied with the provisions of the Patent Law, and filed an application in accordance with the law.
