Design and Implementation of GSM Based Industrial Automation

该拟议项目的主要目的是设计和实施灵活,经济高效,强大的基于GSM的工业一个utomation security system。占领者的便利性和安全性需要基于GSM的工业自动化系统。该系统可帮助您检测入室盗窃,泄漏有害气体,由于火灾而导致的烟雾和检测到可疑活动后,它向所有者编号以及保安人员发出警报信息。有关人员将通过注册移动将一些命令发送到微控制器单元并通过继电器控制工业设备来进行一些行动。

工业自动化或数值控制是使用计算机等控制系统来控制工业机械和过程,减少对人力的需求。现代工业设备和过程的操作和控制需要大量的传感器来监测系统的几个参数。


Design and Implementation of GSM Based Industrial Automation

所提出的系统包括GSM调制解调器,微控制器,各种传感器,relays, memory and LCD Display. If the user wants to control the system from a remote place, he/ she has to send the SMS command from his registered mobile indicating the operation of the device. The GSM modem embedded with Microcontroller receives the user’s command. According to the received message, the Microcontroller will switch ON/ OFF the relays (i.e. specific application).

基于GSM的工业自动化系统的框图显示在下图中。该系统主要由GSM调制解调器和包括所使用的不同传感器的接口电路组成三个组件。

GSM调制解调器的功能是通过RS232串行通信标准用户(通过移动)和控制器之间的远程通信必威体育怎么登录。微控制器连续检查不同传感器的输出并在紧急情况下通过GSM网络发送消息。

这Microcontroller is connected to various devices like a smoke detector, motion detector, IR sensor, LDR through relays. An interface circuit has been designed which includes the programmed Microcontroller and the GSM modem through the serial port of the GSM MODEM, the sensors as input devices and those are connected to Microcontroller and relays.

供电单元

电源单元为不同的用途提供两个直流电压(5V和12V)。下图显示了一个简单的电路,用于从单个电路获得5V和12V电源。

这一个C mains will step down by a step-down transformer T1, rectified by bridge rectifier B1, and filtered by smoothing capacitor C1 to obtain a steady DC voltage level. The IC 7805 voltage regulator used to obtain 5V DC. The IC 7812 voltage regulator used to obtain 12V DC.

Microcontroller- AT89S52

AT89S52是一种低功耗,高性能CMOS 8位微控制器,具有8K字节的闪存(在系统可编程存储器中),其由高密度非易失性存储器技术制造,与工业标准80C51指令集和引脚兼容。

这main role of the 8051 Microcontroller in GSM Based Industrial Automation security system:

在该系统中,微控制器以这样的方式编程,它始终搜索从传感器的输入。如果微控制器由来自任何传感器中的信号中断,那么它将通过发送短信通过GSM Modam向用户手机发出命令。

LCD连接到微控制器以显示调制解调器状态,传感器状态。例如,如果微控制器正在初始化调制解调器,如果有任何情况,调制解调器无法初始化,则用户不知道系统中发生了什么,因此我们正在使用LCD来显示状态。

GSM调制解调器

We usedGSM / GPRS SIM900A调制解调器works on frequencies 900/ 1800 MHz. The modem is coming with the RS232 interface, which allows you connect to a PC as well as a microcontroller with the RS232 chip (MAX232). The baud rate is configured from 9600-115200 through AT command.

它有一个板载稳压电源。使用此调制解调器,我们可以通过Simple AT命令进行音频呼叫,短信,读取SMS,参加来电和互联网等。

特征

  • 双频GSM / GPRS 900 / 1800MHz。
  • 可配置的波特率。
  • SIM card holder.
  • 内置网络状态LED。
  • Inbuilt powerful TCP/IP protocol stack for internet data transfer over GPRS.

这vital role of GSM modem in GSM Based Industrial Automation security system:

Nowadays everything is going to be automated using smart MODEM technology, using this technology we can access any devices remotely.

GSM调制解调器正在使用AT命令与微控制器通信,例如,如果我们要将SMS发送到AA号98xxxxxxxxx,我们必须发送的命令是+ cmgs =“<98xxxxxxxxxxxx>”,

在这个项目中,它用于在未经许可的情况下在他们的家庭或行业发生的事情发生时向业主移动短信。

RS232

RS-232是一种沟通必威体育怎么登录cable, commonly used for transferring and receiving the serial data between two devices. In this project, it provides communication between MODEM and the microcontroller.

烟雾传感器

一个烟雾探测器设备is a smoke sensing device that indicates the fire. Smoke Detectors are very useful in homes, offices, schools and industries. The MQ-2 sensor detects the presence of combustible gas and smoke at concentrations from 300 to 10000ppm.

这可以很容易地连接到微控制器。每当烟雾检测到任何烟雾/火灾时,它会向微控制器发送信号,然后MC将向用户移动发送短信。

LDR(轻依赖电阻)

LDR.is a device that has a variable resistance that changes with the light intensity that falls upon it. This feature allows them to be used in light sensing applications. In this project, we can use this sensor for lights on/off purpose.
