The door magnetic system, as the first line of defense of the smart home security part, can generally be divided into three parts: door magnetic switch, door magnetic sensor (detector) and door magnetic alarm.
Some access control systems are based on a smart bus and the same system platform, so that smart home smart terminals can be easily connected to the video doorbell system gateway and management center to implement guest talk, message, photo and access control functions, and become home safe. The first line of defense. These can also be equipped with smart proximity cards and fingerprint locks, enabling smart linkage, such as synchronized disarming alarms, and turning on lights or modes.
How Wired Magnetic Sensors Work
The function of the door magnetic switch in the smart home access control system is to take charge of the door magnetic flux, energize the magnetic field (close the door), cut off the power and degauss (open the door), install the door magnetic on the door and the door cover, and install the switch in the room, with the automatic The use of door closers, generally can withstand 150 kilograms of tension.
Wired door magnets are more concealed for embedded installations. According to thousands of companies knowing the opening and closing of their induction windows and doors, they are suitable for issuing normally closed/normally open switching signals for wood or aluminum alloy doors and windows. Door magnetism is used to detect whether doors, windows, drawers, etc. are illegally opened or moved. It consists of a wireless transmitter and a magnetic block. The door magnetic system is actually the same as the magnetic principle of the bed. Here's an example of door magnetism.
The magnetic sensor works wireless <br> <br> wireless door is made in two parts and a wireless transmitter module magnet blocks, there are two arrows have a "steel reed" components in a wireless transmitter module, when When the distance between the magnet and the steel reed pipe is kept within 1.5 cm, the steel reed pipe is in the disconnected state. Once the distance between the magnet and the reed pipe is more than 1.5 cm, the steel reed pipe will be closed, causing a short circuit and the alarm indicator will be bright. At the same time, the host sends an alarm signal.
Wireless door alarm wireless alarm signal can transmit 200 meters in open space, can transmit 20 meters in general residential, and the surrounding environment is closely related. Wireless door magnets generally use power saving design. When the door is closed, it does not emit radio signals. At this time, power consumption is only a few microamps. When the door is opened, it immediately emits a wireless alarm signal for about one second, and then stops automatically. At this moment, even if the door has been opened, it will not transmit any more signals.
Wireless door magnetic is also designed with a battery low voltage detection circuit. When the battery voltage is lower than 8 volts, the lower LP light-emitting diodes will be lit. At this time, it is necessary to replace the A23 alarm battery immediately, otherwise it will affect the reliability of the alarm. .
The wireless door sensor is generally installed on the inner side of the door. It consists of two parts: the smaller part is a permanent magnet, and the inner one has a permanent magnet to generate a constant magnetic field. The larger one is a wireless door magnetic main body. There is a normally-open type reed switch. Xiao Bian found that when the permanent magnet and the reed switch are close together (less than 5 mm), the wireless magnetic sensor is in working standby state.

Xiao Bian found that when the permanent magnet and the reed switch are close together (less than 5 mm), the wireless magnetic sensor is in working standby state.
When the permanent magnet leaves the reed pipe for a certain distance, the wireless magnetic sensor immediately transmits a 315 MHz high-frequency radio signal containing an address code and its own identification code (ie, data code). The receiving board identifies the address code of the radio signal. Determine whether it is the same alarm system, and then according to its own identification code (that is, data code) to determine which wireless door sensor alarm.
Switching principle: Mount <br> <br> door sensor is installed in the home more than at the doors and windows, if needed, without having to find someone, do it yourself can be a successful installation. First of all, buy a magnetic switch, and wipe the installation position of the magnetic switch clean;
Secondly, use screws to fix the switch and magnet parts on the door and the door frame, and pay attention to the position. Finally, install the two parts of the cover. At this point, the magnetic switch was successfully installed.
As a smart home system, the components are small, the technical content is relatively low, and the production cost is relatively low. Indeed, in the past when the smart home market became enthusiastic, it became an entrance for many manufacturers or individuals to enter the smart home field, but it also caused a trend to follow suit. Sequelae: The quality of cohabitation damages the reputation of the door and window sensor products in the market. Excessive market output also affects sales. Although the price of door and window sensor products has plummeted, ordinary citizens can easily purchase it, but it still cannot cover up the smart home market. The status and sense of presence have dropped significantly.
The IoT smart home system consists of the family environment awareness interaction layer, network transmission layer, and application service layer. The family environment awareness interaction layer is composed of various sensor nodes with wired or wireless functions, mainly for the acquisition of home environment information, the acquisition of the owner state, and the entry of the visitor's identity characteristics; the network transmission layer is mainly responsible for home information and director control information. Transmission; The application service layer is responsible for controlling the home facility or application service interface.
The magnetic sensor in the door magnetic system is an interactive layer of home environment awareness. The English name of wireless door magneto is Door sensor. Generally, there are two methods used by criminals to enter the house from the door: one is to steal the master's key and open the door; the other is to use a tool to open the door. Regardless of the method used by criminals to enter, he must push the door open.

Generally, there are two methods for criminals to enter the house from the door: one is to steal the key of the owner and open the door; the other is to open the door with tools. Regardless of the method used by criminals to enter, he must push the door open.
Once the thief pushes the door open, the door and the door frame will be shifted, the door magnet and the magnet will also be displaced at the same time, the radio signal will be transmitted to the host immediately, the host will ring the alarm and dial 6 preset telephone numbers. In order to achieve a more intelligent security protection for home life, to ensure the safety of family life and property.
Conclusion:
The products that are really easy to use will not be ignored. The door and window sensor system is small, but it has an extremely important position in the overall scene of smart homes. Thousands believe that with the attention of manufacturers and technological development, the door and window sensors can return to the public once again. Smart home life provides a "small and beautiful" quality experience.
