Specifically, referring to fig. 1, the burglar alarm device 1 includes a door state detection circuit 11, a burglar alarm 12, and a first controller 13, the door state detection circuit 11 is electrically connected to input terminals of the burglar alarm 12 and the first controller 13, respectively, and an output terminal of the first controller 13 is electrically connected to the wireless communication device 5.
In this embodiment, the abnormal opening of the door refers to an illegal entry of the door, and a user generally sets a door state monitoring time period in advance. When the door is not set, the door cannot give an alarm when opened, and if the door state monitoring time period is set in advance (if the sleep time period can be set, and if the owner goes out, the alarm can be given when the door is opened).
In a specific implementation scheme, a client generally sets a certain time period in advance according to conditions, and if the door is opened in the time period, the door is abnormally opened. Meanwhile, the time period can be changed or deleted by the client at any time.
Specifically, referring to fig. 2, the door state detection circuit 11 includes reed switch magnetrons L1 and a 555 pulse oscillator U1; the reed switch L1 is electrically connected to the 555 pulse oscillator U1, in this embodiment, the burglar alarm 12 employs a buzzer, one end of the buzzer BL is electrically connected to the reed switch L1, the other end of the burglar alarm 12 is electrically connected to the 555 pulse oscillator, and the 555 pulse oscillator U1 is further electrically connected to the first controller 13, specifically, to the first controller 13 through the end a. As can be seen from fig. 2, in addition to the above devices, the circuit further includes a resistor R1, a resistor R2, a resistor R3, a capacitor C1, and a capacitor C2 for protection.
In the embodiment, a normally open reed switch is used as the magnetic switch. A Reed Switch (Reed Switch), also called Reed Switch or magnetic Reed Switch, is a magnetic induction Switch element, and its structure is shown in fig. 3, the Reed Switch is mainly composed of two magnetizable reeds 111, the two reeds 111 are overlapped, the overlapped part, i.e. the end of the reeds, is coated with magnetizable contact material to form a contact part 112, and is sealed in a glass tube 113, the glass tube 113 is filled with high purity inert gas, and both ends are sealed by protective resin. In the case of the normally open reed switch employed in this embodiment, in the absence of a magnetic field, there is a very small gap of several micrometers between the two reeds 111, and the two reeds 111 do not contact each other, which corresponds to the off state of the switch. When the permanent magnet approaches the reed pipe, the contacts of the two reeds 111 attract each other and close due to different magnetic poles generated by magnetization.
In the embodiment, the LM555CM chip is selected as the 555 pulse oscillator, and the chip has the advantages of small volume, low manufacturing cost and high response speed and is suitable for an emergency alarm system. Referring to fig. 2, when the door is in an open state, two reeds of the reed switch L1 are opened due to the permanent magnet mounted on the door being away from the reed switch, i.e., the switch is in an open state. Pin 4 is switched to a 5V power supply by the reed switch, and the circuit where the LM555CM chip is located is electrified. At the moment of power-on, the voltage on the capacitor C2 cannot change suddenly, the pin voltages of the pin 2 and the pin 6 are both low level, the pin 3 outputs high level, the power supply charges the capacitor C2 through the resistor R1 and the resistor R2, and the voltage on the capacitor C2 gradually rises. When the voltage on the capacitor C2 is greater than two-thirds of the power supply voltage, the pin 3 outputs low level, the internal discharge tube is conducted, the capacitor C2 discharges to the internal discharge tube through the resistor R2, the voltage of the capacitor C2 gradually drops, and when the voltage on the capacitor C2 is less than one-third of the power supply voltage, the pin 3 outputs high level. The process is repeated for a plurality of times to form oscillation, and the buzzer BL sends out alarm sound through adjusting output square waves.
When the door is in a closed state, the reed switch magnetic control switch L1 is closed, the pin 4 (oscillation reset end) in the LM555CM is grounded, the pin 3 is at a low potential, the output is 0, and therefore the buzzer BL does not sound. The effect of sending an alarm when the door is opened abnormally can be realized by the single circuit module and the installation of the 5V direct current power supply.
In this embodiment, the door state detection circuit 11 and the burglar alarm 12 connected thereto may be integrated on a circuit board, and the first controller 13 may be a single chip microcomputer, and the single chip microcomputer controls the voltage to control the switch of the circuit board. Moreover, the voltage change on the circuit board can be fed back to the single chip microcomputer, the single chip microcomputer can send an instruction to the wireless communication device when receiving the abnormal voltage change, and the wireless communication device sends a short message to the terminal equipment (such as a mobile phone) of a user to send an alarm, so that a remote alarm effect is achieved.

In this embodiment, the second controller 22 is a single chip microcomputer, and four independent buttons are connected to the single chip microcomputer for manually controlling the curtain.
The core component of the curtain control device 2 is a stepping motor.

And the No. 0 and 3 teeth and the A, B phase winding generate staggered teeth, and the No. 2 and 5 teeth and the A, D phase winding magnetic pole generate staggered teeth. By analogy, A, B, C, D when the four-phase windings are powered, the rotor will rotate in the direction A, B, C, D.
Since the second controller 22 in this embodiment is a single chip, the single chip serving as the timing controller should be connected to the stepping motor, but the voltage and current output from the I/O port of the single chip is small and insufficient to provide sufficient driving current to drive the stepping motor to rotate, the motor driver 23 is used in this embodiment, and the motor driver 23 is a 5V driving board of ULN2003, and the specific working principle is as shown in fig. 6.
