Abstract

The invention relates to an intelligent access control system based on a GSM technology. The system can receive data and alarm information from a remote site anytime and anywhere, and the system has fireproof antitheft functions, a cipher function and a gate opening and closing mobile phone remote control function, and reminds through a short message and allows a buzzer to give alarm when a fire or a thief appears. The system includes a control module, a GSM module, a display module, a data acquisition module, a sensor alarming module and encryption module. The intelligent GSM access control system can receive instructions from the remote site and mobile phone information-based alarm, and has very high practical values.

Description

A kind of method for designing of GSM intelligent access control system

Technical field

The present invention relates to a kind of method for designing of GSM intelligent access control system, belong to information communication control field.

Background technology

Nowadays, along with raising and the development of people's living standard, the progress of technology, increasing place needs to use intelligent access control system, as inlet region, the entrance in parking lot and other public places.Permitted eurypalynous gate control system, because it has different features, so the place used is not identical.The feature of intelligence GSM gate control system to receive the instruction of remote site and the warning based on cellphone information, has very high practical value.Such as: be applicable to factory, warehouse, is requiring higher the workshop even intelligent management of family room safety monitoring, the effect that can play.Managerial personnel can understand Disciplinary Frontiers by the information received, and save a large amount of manpowers, material resources and financial resources, improve security and supervisory efficiency.

Summary of the invention

The present invention is a kind of intelligent access control system utilizing GSM technology, and the gsm module of remote door access system can receive data and the warning message of remote station whenever and wherever possible, and this system has following functions:

1. fire-proof and theft-proof function, the system meeting inform by short message when having fire or thief, and buzzer warning;

2. cryptographic function, input secret number;

3. mobile phone can remote control switch door.

This system comprises control module, gsm module, display module, data acquisition module, sensor alarm module, encrypting module.

Embodiment

The introduction of system:

This system comprises control module, gsm module, display module, data acquisition module, sensor alarm module, encrypting module.This system works block diagram as shown in Figure 2.

System module is introduced

Master controller

Main control adopts STC89C52 single-chip microcomputer

STC89C52 introduces: STC89C52 is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontroller, has 8K flash storage able to programme.Use the manufacture of high-density nonvolatile memory technology, with the instruction of industrial 80C51 product and pin completely compatible.On sheet, Flash allows program storage online programmable, is also suitable for conventional programming device.On a single chip, have 8 dexterous bit CPUs and in-system programmable components Flash, height is flexible, the solution of super efficient for numerous embedded Control application system provides to make STC89C52.STC89C52 has following standard feature: 8k bytes Flash, 256 byte RAM, 32 I/O mouth lines, WatchDog Timer, 2 data pointers, three 16 bit timing device/counters, one 6 vector, 2 grades of interrupt structures, full duplex serial port, crystal oscillator and clock circuit in sheet.In addition, STC89C52 can be down to the operation of 0Hz static logic, supports that 2 kinds of software-selectable select energy-saving mode.Under idle pulley, CPU quits work, and permission RAM, timer/counter, serial ports, interruption work on.Under power down protection mode, RAM content is saved, and oscillator is frozen, and all work of single-chip microcomputer stop, and interrupt or hardware reset until next.

Gsm module

TC35 is the highly integrated gsm module of a double frequency 900/1800MHZ.In today that GSM network becomes better and approaching perfection day by day, TC35 has acted on the consistent one's best quality of Siemens, and it is easy to integrated, uses Single-chip Controlling that less cost can be spent in the short period of time to develop novel product.

Secret number module

When the password of user's input is correct, single-chip microcomputer just exports enabling signal, delivers to opening drive circuit, then drives electromagnetic lock to reach the object of enabling.Information, to be shown by LCD, and utilize hummer and the instruction of diode acousto-optic.Wherein, green light emitting diode is bright, and expression is unblanked; Otherwise, represent Password Input mistake and open alarm circuit.Simultaneity factor is by sending out short to cease open the door.Meanwhile, crypto module has changes original old cryptographic function, is achieved the goal by the input of matrix keyboard and the output of LCD display.

Fire prevention module

All smog can be produced during breaking out of fire, therefore detection module of preventing fires adopts MQ-2 smoke transducer, MQ-2 smoke transducer belongs to gas sensor, it is gas-electric transducer, inflammable gas and the aerial content of smog (i.e. concentration) are changed into voltage or current signal by it, deliver to single-chip microcomputer after converting analog quantity to digital quantity by A/D change-over circuit, and then complete the work such as data processing, concentration process and controlling alarm by single-chip microcomputer.

Anti-theft module

Antitheft employing pyroelectric infrared sensor, pyroelectric infrared sensor (being called for short PLR) is a kind of new type of high sensitivity detecting element grown up the eighties.It can detect the change of the infrared energy of human body radiation with noncontact form, and converts thereof into voltage signal output.The window that one is equipped with filter glass has been offered at transducer tip, this optical filter is 7 ~ 10um by the wavelength coverage of light, just in time be suitable for the detection of human infrared radiation, and the infrared ray of other wavelength is absorbed by optical filter, so just, define a kind of special infrared ray sensor being used as detection human body radiation, and sensing range is wide, distance.

Claims

1. the method for designing of GSM intelligent access control system is by a control module, gsm module, display module, data acquisition module, sensor alarm module, and encrypting module is formed.

2. GSM intelligent access control system according to claim 1, has fire-proof and theft-proof function, and cryptographic function and mobile phone can the functions such as remote control switch door.
