Description

Technical Field

[0001] The utility model relates to a passive intelligent detector structure, belonging to the technical field of door magnets. Background Art

[0002] Door sensors are security alarm devices used to detect unauthorized opening or removal of doors, windows, drawers, and other items. Smart door sensors typically consist of two components: a passive terminal with built-in magnetic material (such as a magnet), installed on the side of the security door frame; and an active terminal with built-in magnetic detection and algorithm control circuitry, installed on the edge of the door leaf that can be opened or closed. When the door is closed, the magnetic sensor detects the presence of magnetism. However, when the door is open, the magnetism disappears and the sensor loses its detection. Based on this magnetic change, the sensor determines the door's open or closed state and transmits this information to the smart home system or the user. Smart door magnetic sensors are widely used in home security, particularly in smart home systems. They can be used on household devices with opening and closing functions, such as entrance doors, balcony windows, chests of drawers, safes, and refrigerators. By installing a smart door magnetic sensor, users can monitor the open and close status of these devices at any time, ensuring home safety.

[0003] Passive door sensors no longer require power cables or batteries, are easy to install and operate, and have seen rapid development in recent years. However, existing passive door sensors also have the problem of being unable to detect whether the door sensor is open or closed. When the door sensor fails, users or administrators cannot know whether the passive door sensor is in working condition. Utility Model Content

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a specific component, respectively. The accompanying drawings are highly simplified and use non-precise ratios, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0021] For the sake of clarity, not all features of the actual embodiments are described. In the following description, well-known functions and structures are not described in detail because they would make the utility model confusing with unnecessary details. It should be considered that in the development of any actual embodiment, a large number of implementation details must be made to achieve the specific goals of the developer, such as changing from one embodiment to another according to the limitations of the relevant system or the relevant business. In addition, it should be considered that such development work may be complex and time-consuming, but it is just routine work for those skilled in the art.

[0022] refer to Figure 1 : A passive intelligent detector structure includes an outer cover 1, a door magnet and a coil 4, the door magnet includes a door magnet A2 and a door magnet B3, the coil 4 is connected to the outer cover 1, the coil 4 is connected to the door magnet A2 through a power cord, the door magnet A2 and the door magnet B3 are wirelessly connected, a card slot is provided in the outer cover 1, the coil 4 is fixed in the card slot, the door magnet A2 and the door magnet B3 are magnetically connected, and the door magnet A2 and the door magnet B3 are connected through magnetic materials and circuits.

[0023] The signal from coil 4 is transmitted to door sensor A2, the signal from door sensor A2 is transmitted to door sensor B3, the signal from door sensor B3 is connected back to the smart key, and the signal from the smart key is transmitted to the lock management platform.

[0024] The smart key is attached to the outer cover 1, and through the interaction of coil 4 and door magnets A2 and B3, a signal is generated and transmitted back to the smart key. The smart key transmits the information back to the lock management platform, and the management personnel can query the open and closed status of the door magnet.

[0025] refer to Figure 2 :U1 is a wireless receiving module, J3 and J4 are connected to the receiving coil, through capacitor C3, Schottky diode D2, capacitor C4, and then connected to the 2nd and 4th pins of the U1 wireless receiving module. The 3rd and 4th pins of U1 are connected to Schottky diode D3, and the 3rd pin of U1 is connected to inductor LP1. Resistor R1 is connected between pins 1 and 7 of U1. Pin 5 of U1 is connected to resistors R4 and R2 and connected to inductor LP1. U1 is connected to capacitors C25, C26, C5, C22, and C23 through these components, and outputs a 5V0.5A DC power VCC_WL.

[0026] U2 is an LDO linear regulator. Pins 1 and 3 of U2 are connected to VCC_WL, and pin 2 of U2 is connected to GND. After passing through U2, VCC_WL is connected to capacitors C27, C1, C2, and C24, and a power supply VCC_3.3V is output at pin 5 of U2.

[0027] U4 is the door magnetic status detection module. VCC_3.3V is connected to resistor R8, and the first pin of U4 is connected and connected to capacitor C20; the second pin of U4 is connected to GND, and the third pin of U3 is connected to resistor R7 and capacitor C21, generating a signal HAL_OUT. The signal HAL_OUT is electrically connected to pin 11 of U3 and connected to the door magnetic, which is used to output the door magnetic switch signal to U3.

[0028] U3 is the main control MCU, which detects the door magnetic signal through U4. When HAL_OUT is high, U3 generates a door opening signal and transmits it to the transmitter via Bluetooth broadcast; when HAL_OUT is low, U3 generates a door closing signal and transmits it to the transmitter via Bluetooth broadcast; the transmitter determines the door magnetic switch status at this time by receiving this signal. This process can monitor in real time whether the door magnetic is in normal working condition and whether there is any fault, saving costs.

[0029] 6. In addition, Q1 and Q2 constitute the driving circuit of the driving motor. The 43rd pin of U3 is connected to capacitor R1 and Q2. When the door magnetic status signal HAL_OUT is low, the 43rd pin of U3 outputs a high level, turning on Q2. After Q2 is turned on, Q1 is turned on, connecting the VCC_WL voltage to the motor J1 to drive the motor to rotate; when the door magnetic status signal HAL_OUT is high, the 43rd pin of U3 outputs a low level, Q2 is cut off, Q1 is cut off, and the motor stops rotating. This process is to output voltage to control the rotation of the motor, and then control household appliances with opening and closing functions such as entrance doors, balcony windows, drawers, safes and refrigerators, such as switches and locks.
