Intelligent building supervisory system of the present invention, when there is alert in house defence area, system can automatic acousto-optic electric alarm to give intruder more powerful deterrence; And realize long-rangely informing householder's alert by gsm module, make it to take effective emergency measure immediately, make anti-theft effect better; Add the measure of encrypting and decrypting in addition, to realize the switching of System Deploying and disarming state, really achieve the function into householder's on-demand service.This system also extends to bed rearrangement building, and even whole residence district, therefore has wide usage space and development space.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment schematic diagram of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the present invention's do, but embodiments of the present invention are not limited thereto.
Intelligent building supervisory system of the present invention, comprise single-chip microcomputer, the warning circuit be connected with single-chip microcomputer, gsm communication module, encrypting and decrypting device and signal processing circuit, described signal processing circuit comprises infrared receiving device, and described intelligent building supervisory system also comprises at least one infrared probe.
System utilizes pyroelectric infrared sensor to defence area real time monitoring, and single-chip microcomputer is the core control part of whole system, and the switch alarm signal of sensor-triggered is input to single-chip microcomputer after signal processing circuit; Single-chip microcomputer is judged signal, then gives an order, and makes system carry out work in a certain order by topworks.Here comprise: when intelligent detector unusual circumstance, adopt acoustic scene, optical, electrical warning on the one hand, to deter offender, on the other hand, introduce advanced GSM mechanics of communication, utilize gsm wireless communication network, the situation in family is passed to householder, and householder is after obtaining information, effective emergency measure can be taked immediately, as, phone local property, 110 emergency centers etc., emergency treatment is carried out to accident; In addition, native system is deployed troops on garrison duty and disarming state to switch by encryption and decryption.System architecture as shown in Figure 1.
In electronic anti-theft field, pyroelectric infrared sensor is because of its good concealment, and power consumption is little, and cheap, technical feature is stablized, and is subject to the welcome of users.Its principle of work: body temperature, generally at 37 degree, can send the infrared ray of wavelength about about 10 μMs, the infrared probe of sensor carries out work by the infrared ray detecting human-body emitting.Its induction source adopts pyroelectricity element usually, can lose charge balance, and then outwards discharge electric charge when receiving human infrared radiation temperature and changing, follow-up through a series of signal treatment circuit, just can produce alerting signal.In order to only to the sensitive for infrared radiation of human body, show up in the radiation of this sensor and be usually coated with special Fresnel optical filter, to strengthen gathering infrared ray, play the effect of effectively restriction environmental interference.
That the design adopts is the new generation of wireless communication gsm module TC35 that Siemens Company releases, the operating voltage of this module is 3.3 ~ 5.5V, 900MHZ/1800MHZ two frequency ranges can be operated in, carry RS232 communication interface, machine communication can be connected with PC, single-chip microcomputer easily, safely, reliably realize data, voice transfer, Short Message Service and fax in system schema.Wherein, due to short message have realize simple, communications cost is low, good confidentiality, directly user oriented mobile phone and not by features such as region restrictions, be utilize communication modes the most widely at present.In this warning system, using user mobile phone as receiving terminal, when having alert to occur in manager, mobile phone can receive an alarming short message from intelligent alarm system automatically, so just can realize remote alarms in real time, reliably, efficiently.
When just heat outputting electric signal after the infrared ray that Sensor monitoring sends to human body, because this signal is very faint and be mingled with undesired signal, therefore devise special signal processing circuit and (adopt operational amplifier, peripheral circuit is coordinated to form the amplifying circuit with bandpass filter function) isolate pyroelectric signal, and amplified thousands of times; By the optimal design of parameter, cooperation comparator circuit eliminates the interference that flowing hot-air causes further.Then after amplifying two-stage, isolated pyroelectric signal carries out analysis judgement.For false action-proof, signal will compare with threshold level, produce high level signal and export.The signal finally produced by difference probe is incorporated into the INT1 mouth of single-chip microcomputer by rejection gate, to be interrupted to perform corresponding action; When not interrupting, system is in holding state, can reduce system power dissipation like this.
When single-chip microcomputer monitor someone enter in defence area time, intelligent alarm system just carries out audible alarm by hummer, and the diode that simultaneously glows glimmers, play deterrence offender effect.High pressure generator is have also been introduced in the design, after the relay normally open contact connected is closed, secondary output high pressure can be made through boosting, caused alarm unit outer cover, if criminal is intended to destroy warning device, when touching its shell, even if with gloves, high pressure also can puncture gloves by human body discharge, and this will effectively stop the further crime of offender, but also can not cause permanent injury to it.
The communication of single-chip microcomputer and TC35, general employing work in series mode 1, data layout is 10.Wherein, 1 start bit (0), 8 data bit (lowest order is front), 1 position of rest (1).The value of its baud rate depends on the value of the SMOD position in the flood rate of timer T1 and special function register PCON.TXD and RXD level due to single-chip microcomputer is Transistor-Transistor Logic level, and through RS-232 interface when TC35 carries out communication, Transistor-Transistor Logic level and RS-232 level incompatible, so during both interfaces, level conversion must be carried out, use MAX232 chip at this.
By the method to system encryption, deciphering, carry out deploying troops on garrison duty and the switching of disarming state.In system initialization process, in single-chip microcomputer, be provided with specific password.When head of a family goes back home, by correctly inputting this password to withdraw a garrison.Now, in indoor, free activity can not produce warning.When going out, operable key dish makes system reenter armed state.It is to be noted that under the state of deploying troops on garrison duty, after alerting signal being detected, whether system after one section of time delay, need be verified this signal and exists again, if exist, and does not withdraw a garrison, then produces corresponding alarm (acousto-optic-electric effect and short message inform householder).This time delay is very necessary, and the defence area left from establishing due to owner needs a period of time, if do not have this time delay, so owner oneself is through defence area, also can produce false alarm.
As mentioned above, the present invention can be realized preferably.
