Published Online June 2017 in MECS

Integrated intelligence is a mechanism by which a specific application device as a combination of microcontroller, protection sensor with integrated signal status and distribution channels of the signal communication module control management intelligent systems, they refer to other technologies with similar convenience in the appearance of the machine / device communication machine / device. Integrated information system is present in many different devices and areas such as health divisions, agriculture, transport, defense and performance. IoT controllers use different communication protocols over the Internet. Aspire of this work is to provide a security system where they connect with each other, with the IoT development in the modern era. In this work, we use a microcontroller (AVR-RISC processor Alf and Vegard), PIR (passive infrared sensor), a GSM module and a smart phone to start an idea. The idea, focusing on the need to design a security system that is moderately tangible. For example, if a family goes to Hometown or wherever you leave your room / house, it must be something that keeps control of the smart home. If someone inside the house should be a device that will make you alerts, like to take pictures, record videos. The best competition of these efforts is a security system through intelligent IP device to access the Internet of things everywhere protocol.

We want to know about the monitoring system that has linked the attachment toward the Internet used for distant screening. During earlier period, safety systems must be monitor through a guardian who was protected during a day by every surveillance room that would be monitored to ensure nothing. It is very important now to have days; the prospect of our remote security system is ease to notice in real time. This system of progressing a message directly to the mobile phone from the cell to facilitate, detect that your surveillance camera capture an incident. This system protects against theft. By being able to see your DVR over the internet, you are very happy to immediately stop a crime.

• III.    Gsm Module (Sim900A)

GSM module is used to send / receive messages and make / receive calls as a mobile phone a SIM card from network source. This system done when GSM module connects to the AVR, and then a SIM card provides a link from a server's GPRS cover. The module uses the SIMComm function. It is be able to communicate easily with the module through AT commands. GSM library contains several methods of communication with the module. The GSM modem can work with any GSM network operator SIM card like a mobile phone with its own unique telephone number. The advantage of this modem is the RS232 interface can be used to communicate and develop integrated applications. Control applications such as SMS, data transmission, remote monitoring and recording can be easily developed with this. The modem can be connected directly to the serial port of the PC or to a microcontroller via MAX232. It can be used to send / receive SMS and make / receive voice calls. It can also be used in GPRS mode to connect to the Internet and run many recording applications and data control. GPRS mode can also connect to an FTP server and files for data download this GSM modem registration is a GSM Modem SIM900A Quad-band GSM modem and run very flexible for easy integration with direct applications. It supports functions like voice, SMS, data / fax, GPRS and integrated TCP / IP stack. Up to a mobile network can be connected; the module requires a SIM card provided by a network provider.

It is a wireless module that is not very compact and reliable. SIM900A is a dual GPRS / GSM full-band SMT module that can be integrated into client applications, which allows you to take advantage of small size and cost-effective solutions.

• IV.    Passive Infrared Sensor

PIR sensors capture the motion allows to sense movement, constantly to prove if a human being moved in or out from the sensor area. They are tiny, low power, cheap, uncomplicated to utilize. For this reason are often found in devices in households and businesses. It also referred to as PIR sensors, "PIR", "pyroelectric" or "IR motion."

For the most part, PIR modules contain 3-pin connector on the surface or underside. The pin can differ among the module triple the pin! It is frequently screened taking place at the exact side of compound a pin, another signal of the end will be energy. The energy input is generally 3-5VDC but can be as high as 12V. Sometimes larger elements do not contain direct access and alternative simply run a relay in this case; no land, food and two switch connections.

The output relay can be an "open collector" - that is, it needs a pull-up resistor. If you do not get an uneven output make certain to connect a 10K pull-up among the signals and power pins.

• V.    Embedded C

During the years of microprocessor-based systems, programs have been developed, for the use of counters and fused into the EPROM. There was no mechanism to find the program was carried out. They have checked LEDs, switches, etc., the proper implementation of the program. A small number of developers have in circuit emulator (ICE), although those are very expensive and not much consistent. Over moment, the utilize of certain set of processor systems by a program language has been compact for Embedded C that reduces the integrated choice of    programming language and moves.

Programming language C is the most commonly used / integrated controller processors. The arrangement is also used, in particular, however, to implement parts of the code wherever the timing, efficiency code extent etc. They are very important.

Because the assembler programs are explicit headed for processor assembler language, there was no convenient between the structures. To prevail over this drawback, a number of high-ranking languages, include C, emerged. Further languages such as PLM, Modula-2, Pascal, etc. as they came other than not widely accepted. Among them, C has gained extensive recognition, not just for embedded systems, but in addition for office applications. Although C has mislaid its luster like a main language for universal applications, and yet it have a physically powerful in embedded encoding. Because of the great recognition of C in embedded classification, they came across a variety of types of supporting tools such as compiler and cross-compiler, ICE, etc. All this has made the development of embedded systems easier with C. The assembler language seems more embedded for programming Systems to be an obvious choice. The use of assembler language, however, develops on limited effectiveness in terms of code size and speed. In addition, the assembler code leads to higher costs of software growth in addition to code convenient is not present. The development of undersized codes is not a big difficulty; however important programs/task is getting more and more complex to handle in assembler language. Find high-quality programmer assembly, it has also turn to tricky. Therefore, the advanced language is chosen for embedded programming systems. Embedded C utilizes the majority of the syntax and semantics of the C standard, for example the function main (), the definition of variables, the declaration of the data type, the conditionals (if, switch statement), the trailing (while, for) functions, the arrays and strings, set, bit operations etc…

Note:

• 1.    Compare with assembler language, written by C Code is further consistent, scalable more convenient among different platforms.

• 2.    C compilers are currently used for practically each and every one of the embedded campaign and currently many experienced programmers in C.

• 3.    Unlike the arrangement, C has the advantages of CPU independence, rather than specific microprocessors / microcontrollers or systems. It allows users to more easily develop programs that can run on most systems.

• IX.    Usbasb Programmer

  USBasp is an integrated USB controller circuit for Atmel AVR-based controllers. It consists only of one or ATmega88 atmega8 and a pair of passive components. The programmer uses a USB controller firmware only; a special USB driver is not required. To use, this programmer must be installed in USBASP Windows drivers. The power comes really USB programmers, which could be very few large power capacity the USB drive could be damaged. In general, more current 100mA, the target card must be provided with a separate source. By manipulating bridges fig.8 the programmers can configure different energy options. Programming must ensure that the programmer can speak with support for software and chip targets. To do this, you can perform read operation (read backup or flash AVR) support software. If the operation is successful, it means that the programmer can communicate with the supporting software and connect it to the target board. If it fails, you must find the causes. The programmer works much more stably when the bridge "CLOCK SLOW" (

However, in order to load the microcontroller program (hex file) with the programmer USBASP, you need the appropriate software. Fortunately, there is a free open source program to download, download or manipulate the Flash, EEPROM and AVR microcontroller fuses over the programmer. It is part of the software packages. You can easily install the Sinaprog or eXtreme burners, which has a number of software development tools for Atmel AVR code open.

It communicates with PD1 Tx UART with a transmission rate of 9600 bps is used.

• B.    Installing a CC Cam DVR for Remote Viewing Over Internet

A few basic things are required to begin:

Live Internet Connection: Directly connecting to the Internet it may come from close to your ISP. In order to be able to provide better, higher speed. However, it is still possible to look at the low-speed connection system, such as from a remote DSL.

Router: A router is a tool for transferring information among network connections. It allows you to unite several devices to connect to the Internet. Today, many families have a wireless router that can connect to the wireless Internet. The wireless router does not require remote access to the DVR. Some brands of Linksys (Cisco), D-LINK, Netgear, Belkin.

Ethernet Cables: It is commonly used CAT5 (Category 5) cable connected to the Internet. Most DVRs have the ability to remotely access ports that can connect to a CAT5 cable network. The manufacturer also includes a cable with the system, but as long as you do not intend to connect to the router around the DVR, you most if the cable is too short. Connect the modem to the router and you need an Ethernet cable. Routers are usually Ethernet cables too short.

DVR with the ability to be remotely viewed: It does not have to show the ability of all DVR distances. Some video graphs are intended for registration and do not have the ability to connect to them via the Internet. Contact the DVR manufacturer or user controller; make sure you can do this with DVR.

Monitor: When you first make it so that you can view all the settings are set to connect to the DVR, you need to monitor the type. Once these settings are configured, If the remote system is being displayed, the monitor is not necessary.

• 1.    Make sure your modem is connected to the Internet. Normally, there is a light on the front panel of the modem. The status indicator will tell you that it works. Because all the different modems are available from your service provider's information or files. Please go beyond the scope of this article to install the pattern configuration. It is necessary to continue to complete this step.

• 2.    Connect the modem to the router's Internet port. Typically, the router has a port connected to the Internet. These ports are usually far away from the other ports on the back of the router. The port on the back of the router is connected to the Internet. Use a CAT5 cable connection.

• 3.    Put the DVR on a data port on the router. Most routers, at least four ports are equipped with hardware to connect to the Internet. Also with CAT5 cable connection. In the first install, as long as you do not move from the router DVR go, there is no need for length CAT5. After the initial configuration of the built-in DVR cable is complete, you can move the DVR at any time.

Now that you have your hardware and configuration connected, make sure the whole thing is running and running. Then confirm the sub sequential step to arrange your router, DVR and quickly you can see from afar. All of their DVRs have the same interface when you type configure so that they are virtually identical. Other DVRs can have menu that appear a bit dissimilar, other than the parameters are usually the identical. This also applies to the router settings.

• C.    Set the DVR

Connect your DVR to the user name and password provided by the company: If the DVR was earlier configured to use management credentials. Select the Network Setup menu. In this section, you can allocate an IP address to the DVR. It determinate the internal static IP address. (This typically starts with 192.168.XXX.X). I propose you to start with these settings, they can still change later.

• a.    IP ADDRESS: 192.168.1.110 (This determinate the IP address of the DVR)

• b.    SUBNETMASK: 255.255.255.0 (Leave it if your system has changed a subnet)

• c.    GATEWAY: 192.168.1.1 (usually the IP address of the router)

• d.  TCP: 37777

• e.  UDP PORT: 37778

• f.    HTTP PORT: 88 (you can make use of port 80, but there are internet service providers using port 80. Normally, only block changes will be on the safe side).

Port forwarding on your router: The subsequently article you want to accomplish is port forwarding on your router. This will be necessary to unite your DVR from a remote setting. If you only write your peripheral IP address in your browser, the router doesn’t need to recognize which device to access. There might be several super computers and strategy on the network, thus you have to inform the router specifically to assign a type of card to all the ports that you have configured to connect.

• XI.    Connected Modules With Working Principles

Fig.10. Connectivity of Circuitry Diagram

The first step of this project was to know how many punches per mile PIR mine put out of service. The output of the PIR is a number of the pulses per mile in a 5 volt square wave signal.

Fig.11. Sensor Input and Output Signal

In PIR sensors, a small trimming potentiometer called TIME. It is a controllable resistor 1Mohm, which is fatherly to a 10K series resistor. Moreover C6 is 0.01uF.

Tx = 24576 ∗ (10K + R time) ∗ 0.01uF

When R time potentiometer turned counterclockwise completely (0 ohms), then

Tx = 24576 ∗ 10Κ ∗ 0.01uF ∗ 2.5 sec(approx)

When the potentiometer is fully turned back R time upward towards the clockwise 1 Meg, then

Tx = 24576 ∗ 1010Κ ∗ 0.01uF ∗ 250 sec(approx)

If R Time is in the center, it would be concerning 120 seconds (two minutes), so you can customize it as needed.

The data received from sensor is taken in logic ‘1’ and is stored by using delay time. After it transmit the message using GSM module, the code for this GSM module is given in AT Command. This function informs the user of an SMS message when the movement of a person is detected. This is not only ensuring the safety but also informs the user that “A PERSON IS IN THE ROOM. GO TO THE FOLLOWING LINK 192.168.XX.XX:XXXX ”.

• XIII.    Conclusion And Future Scope

The proposed safety system is successfully tested and implemented in a confined space. This work can also be linked to other fields of application. The power supply circuit from a 5V battery will run down at a time, not long circuit the one and after a few hours. This limitation can be solved by connecting the system to the current output from the adapter 5V DC 110mA (0.55Watt). Similarly, the cam CC also consumes the configuration of energy. This circuit of the safety system can be modified for automatic closing of the door using the above procedure. For high gas for safety reasons manage the level of O2 and CO2 to increase or decrease. Otherwise, the entire project can be modified to help us save our home / industries from external threats when we get away from our home / industries.
