Detailed Description

The present invention will be further explained with reference to the drawings and the embodiments.

Please refer to fig. 1, this embodiment provides an alarm system based on wifi internet of things, which includes a mobile terminal, a host and a detector; the host comprises a main control CPU, a wifi module, a status light indicating module, a wireless receiving module, an alarm module and a power management module; the main control CPU is respectively connected with the wifi control module, the status lamp indicating module, the wireless receiving module and the alarm module; the power management module provides power for the host; the host is connected with the detector through the wireless receiving module. The detector comprises a door magnet and an infrared sensor.

As shown in fig. 2, the main control CPU adopts an STM32F030C8 single chip microcomputer module.

As shown in fig. 3, is a WiFi control circuit, and the WiFi module is controlled by the chip DC-2668W24

As shown in fig. 5, the alarm module includes an alarm circuit, which is divided into three sounds of high, middle and low, and is controlled by the main control CPU;

as shown in fig. 6, the wireless receiving module employs RF 220. The RF220 is a receiving module, all accessories are subjected to code matching through the receiving module, wireless signals are received and then transmitted to the main control CPU, and the accessories are known to be matched.

As shown in fig. 7, the host is further provided with a wireless transceiver circuit for expanding the wireless alarm number. The main control CPU transmits the received signal to the encoder HS1527, the encoder generates an address code and then transmits the address code to the FS110 transmitting module, and the transmitting module transmits the signal.

As shown in fig. 8, the status light indication module adopts a three-color light, which is controlled by the main control CPU, and the low level is active.

As shown in FIG. 9, the host is further provided with a code matching and distribution network circuit, the WPS enters a distribution network mode by long pressing for 3 seconds, and the WPS enters a code matching state by short pressing for LEARN.

As shown in fig. 10, the host is further provided with a low-power detection circuit and a power failure detection circuit, and when a low point or power failure is detected, information is pushed to the mobile terminal through the wifi module.

As shown in fig. 11, the power management module includes a system power circuit including a main power supply and a backup power supply; 4.0V main power is provided by the AP1513S chip, and 4 AA batteries are used for providing backup power.

In this embodiment, after the detector detects the intrusion signal, the intrusion signal is transmitted to the host by a transmitting module of the detector (through an encryption algorithm of AES); the wireless receiving module of the host (the equipment is matched by the authority of the host before, and cannot be matched if the equipment has no authority) receives the signal, the data is transmitted to the main chip, the main chip determines the state of the equipment according to the signal, then the state is transmitted to the server by the wifi module (encrypted by using an MQTT protocol through the internet) and is notified to the mobile phone end, and therefore one-to-one correspondence between the equipment and the mobile phone is achieved.

The method for reminding the unclosed door comprises the following steps: when the host computer detects the door magnet, the door magnet has a code for closing the door and opening the door, the host computer recognizes and records one state first during pairing, and then the code sent by the door magnet is compared with the previous state to determine whether the door is not opened; when the door is not closed, at the moment, fortification is carried out or fortification is carried out at home, the host can prompt that the door is not closed, please close the door and try again, and a warning sound is sent out.

The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
