Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: intelligence house burglar alarm system includes: a housing 10, an intrusion alarm module 30, an information collection module 50, and a PCB board 60.

Further, the information collecting module 50 specifically adopts a pyroelectric infrared sensor, which can respond according to the change of infrared energy emitted by a human body, and when such devices test the change of the infrared energy of the human body, the sensor does not need to be very close to the human body and can also be measured at a certain distance from the human body.

Furthermore, when the pyroelectric infrared sensor is powered on, the pyroelectric infrared sensor does not enter a working state immediately, a process is needed, the process is approximately 1 minute in duration, small detail problems need to be noticed when the pyroelectric infrared sensor is used, the sensor is very high in sensitivity, judgment of the sensor is possibly misled, influence factors are prevented, and therefore misoperation caused by interference signals is avoided.

Furthermore, the sensing module of the pyroelectric infrared sensor adopts a double-element probe, the window of the probe is rectangular, double elements (A element and B element) are positioned at two ends in the longer direction, when a human body passes from left to right or from right to left, the time and the distance of the infrared spectrum reaching the double elements have difference values, and the larger the difference value is, the more sensitive the sensing is. When a human body moves from the front to the probe or from top to bottom or from bottom to top, the double-element can not detect the change of the infrared spectrum distance, and the induction is insensitive or does not work.

The intrusion alarm module 30 includes an LED indicator 31, a buzzer 32 and an alarm circuit 33, and the LED indicator 31 has three groups.

Furthermore, the intrusion alarm module 30 is mainly formed by connecting a proper LED indicator 31 and a buzzer 32 to the port position of the chip, connecting three different LED indicators 31 to three ports P20, P21 and P22, wherein three different colors respectively represent different states during alarming, connecting the buzzer 32 to the port P23, wherein a triode is required to be additionally connected to the outside of the buzzer 32, one port with positive polarity of the buzzer 32 is connected to the emitting end of the triode, the other port of the buzzer 32 is grounded, the base is mainly controlled by a nand gate and a pin P23, if the pin P23 is in a low level state, the output state of the nand gate is in a high level, when a switch of the power supply is turned on, the current is also connected, the input of the power supply and the input of the singlechip are both in high voltage, and the current cannot flow into the triode under the high voltage condition, the triode is in a cut-off state, and the buzzer does not sound at the moment; on the contrary, when the voltage of P23 pin is high level, when the voltage of NAND gate output was low level, we opened switch at this moment again, the electric current can circulate, the voltage of power output at this moment is high voltage, and the voltage of singlechip output is low voltage, the electric current at this moment will pass through the triode, and then flow to bee calling organ, because there is the electric current to flow through bee calling organ, so bee calling organ at this moment will send alarm information because of being driven, the main effect of the triode on bee calling organ is like the switch, when the triode reached under own saturation state, bee calling organ just was driven to respond.

The power switch 80 and the power circuit 90 are electrically connected to the single chip 61.

Wherein, still include: a reset circuit 70.

The reset circuit 70 is electrically connected to the single chip 61.

Further, an area in the anti-theft alarm system is called a delay precaution area, in the design, after an arming task is set for the system, the system automatically provides a time period for a defense area, the time period is delay time, if the delay time is over and the system is triggered, the triggered delay area is about to be entered, at the time, the controller sends out an alarm signal of the controller, the buzzer sounds to generate an alarm sound, and for some signals needing to cancel the anti-theft alarm, the system needs to be subjected to further disarming processing operation within the set delay time, so that the alarm behavior can be avoided perfectly.

Detection port 11 has been seted up on the surface of shell 10 top, the inside top of shell 10 is located detection port 11 department fixed mounting and has mounting bracket 12, information acquisition module 50 fixed mounting is on mounting bracket 12 surface.

Wherein, a base 20 is fixedly installed on the bottom end surface of the housing 10.

The working principle is as follows: when the system is used, the system is initialized at first, a circuit is closed, an interruption source is opened, when a person intrudes, the infrared pyroelectric sensor senses a signal, the STC89C52 single chip microcomputer responds to external interruption, and then the intrusion alarm module 30 also responds to send an alarm; if the infrared pyroelectric sensor does not detect signals all the time, the single chip microcomputer system is in a waiting state all the time, and the program is circulated all the time.
