Description

A kind of novel burglar alarm

Technical field

This utility model relates to a kind of burglary-resisting installation, particularly relates to a kind of novel burglar alarm.

Background technology

Current often have a lot of family to be patronized by thief owing to being fitted without burglary-resisting installation in house, and such potential safety hazard brings the biggest puzzlement to people.For an automatic detection warning, and can recognize that indoor environment state facility it is desirable to see.

Utility model content

The purpose of this utility model is to provide a kind of novel burglar alarm, uses human detection design, by using whether sensor detection local environment has people close, realizes to indoor design condition real-time detection.

The purpose of this utility model is achieved through the following technical solutions:

A kind of novel burglar alarm, is made up of single-chip microcomputer, infrared sensor of the human body, CC2530, LED, buzzer；Described infrared sensor of the human body connects single-chip microcomputer, and described single-chip microcomputer connects CC2530, described CC2530 and connects buzzer, and described CC2530 connects LED.

Described single-chip microcomputer uses STC89C52 single-chip microcomputer.

Described system is to utilize the wireless architecture in ZigBee technology to realize data transmission, and by infrared human body sensor acquisition, whether someone swarms into, it is achieved the detection to human body, it is achieved the antitheft of full tunnel is deployed troops on garrison duty；Multiple terminal node is set, utilizes coordinator to set up network, form a LAN.

The beneficial effects of the utility model: this utility model uses human detection design, by using whether sensor detection local environment has people close, realize to indoor design condition real-time detection；Whether infrared anti-theft alarm can detect has people close, will produce the level change of correspondence.

This utility model is mainly based upon Zigbb wireless communication module to infrared anti-theft alarm system, and this system is broadly divided into two parts of hardware and software.Hardware components is made up of sensor circuit, single chip circuit, CC2530 circuit, power circuit, warning circuit, control circuit, power circuit etc..Main with single-chip microcomputer as core, single-chip microcomputer can identify low and high level, and infrared sensor support is exported low and high level.Software section is then divided into Single Chip Microcomputer (SCM) program, zigbee coordinator process, three parts of zigbee terminal program.When the outer pyroelectric sensor of human body red heat detected people near when, single-chip microcomputer produces level change, the information detected just is sent to coordinator by single-chip microcomputer, coordinator is sent to terminal, after terminal receives data, signal is carried out data transmission by serial communication, corresponding parsing after then single-chip microcomputer receives signal, can be done, and determine whether to start warning by the data signal of parsing, thus realize Automated condtrol.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in further detail.

Embodiment 1

As it can be seen, a kind of novel burglar alarm, it is made up of single-chip microcomputer, infrared sensor of the human body, CC2530, LED, buzzer；Described infrared sensor of the human body connects single-chip microcomputer, and described single-chip microcomputer connects CC2530, described CC2530 and connects buzzer, and described CC2530 connects LED.

Described single-chip microcomputer uses STC89C52 single-chip microcomputer.

Embodiment 2

This utility model is to utilize the wireless architecture in ZigBee technology to realize data transmission, i.e. ZigBee technology and sensor technology.By infrared human body sensor acquisition, whether someone swarms into, it is achieved the detection to human body, it is achieved the antitheft of full tunnel is deployed troops on garrison duty.Multiple terminal node can be designed, utilize coordinator to set up network, form a LAN, need the place of monitoring to carry out laying sensor at any one.

In subnet, communicate between central node controller and master controller and between each node and use advanced technology of wireless sensing network, automatic network-building, Zigbee is used to carry out networking, select is 2.4GZ-stack agreement, user can be carried out freely using, it is possible to automatic network-building, is formed and without communication cost.So practice when, highly promote.

In order to reduce the power consumption of wireless control system, can be programmed node in the way of utilizing interruption, infrared sensor is to automatically identify when having people when, can produce a level change, when level changes when, the interruption of ZigBee program is utilized to be operated to wake up CC2530 up.

This utility model is broadly divided into the board design of coordinator and terminal, this is that the hardware needed carries out providing, hardware mainly needs to design the minimum system of CC2530, the hardware of this ZigBee to be ensured can normally work, just can go to adjust the problem of software, there is also the need to the networking lamp control module of ZigBee.This lamp is primarily to realize allowing ZigBee to ensure that ZigBee the most normally sets up network and adds the mark of network.In addition also needing to the circuit of infrared human body induction module, this is primarily to allow sensor can detect human body, realizes reporting to the police.Certainly buzzer circuit, LED circuit etc. are also needed to, it is ensured that whole normal circuit operation.Here power supply uses the mode of battery to power, and such mobility operability is very convenient.Strengthen practicality.

The framework that main circuit is wanted mainly comprises as follows: single chip circuit, sensor circuit, CC2530 circuit, control circuit, power circuit and warning circuit etc.

Control circuit is made up of single-chip microcomputer STC89C52, mainly realize going infrared sensor of the human body to have detected whether that people is close, if someone, hardware is just driven to be operated, ZigBee coordinator is sent data to by serial ports, data are wirelessly sent to terminal by ZigBee, after terminal receives data, just drive Control photographic head and realize driving buzzer to report to the police.Current estimated people enters family and prepares in real time theft, and user can do buzzer warning with the information that ZigBee returns or can dial 110 and do not encroached on to the rights and interests protecting oneself.

The advantage selecting this mode is to eliminate the trouble of wiring, family is allowed to need not be full of so much lead-in wire, the most gladly seeing for the person of house, the wireless layout type used the most here is particularly suitable for many places and prevents detection from a little needing not worry about the trouble that wiring attracts.Certainly ZigBee is advantageous in that and wireless can deploy to ensure effective monitoring and control of illegal activities and support networking, it is possible to carries out detectable signal at the local detector of placing arbitrarily needing detection, then can get alarm signal at any time, safeguard safety.

First single-chip microcomputer STC89C52 can initialize serial ports, it is ensured that serial port baud rate is 9600.So it is to ensure that serial ports can be given to ZigBee end by transceiving data normally.Because ZigBee end is also to design the baud rate 9600.In order to the level of infrared human body sensor can be gathered.By the way of serial ports, ZigBee terminal is sent the data to when detecting that high level produces.

Terminal design here it should be noted that protocol stack is to need terminal to add after network, adds the network that coordinator is set up, in the middle of the function of the transceiving data that the most just can carry out correspondence normally.Can wait among network to be added the most always, and cannot normally work.So after adding network, ZigBee will utilize serial ports to receive data, and the thinking of serial ports design here is the function of external interrupt.Here it is advantageous in that and can effectively utilize CC2530 to go other thing more dry, without to wait pending data always, improve efficiency.
