Introduction to Remote Notice Board Using GSM With SMS Project:

The world is shrinking with time because today people from all over the world can easily communicate with one another in just a matter of seconds. Digital techniques of communication are the main brainchild behind this success and with the passage of time these techniques are successfully developing more and more.

Advancement control and communication has become important in all parts of the world. The use of cellular technology – mobile phones have increased drastically in the past years.

The main motto of smart Notice Board Using GSM project is to use mobile phones to receive the message and then send it for display to notice board. This project is designed with the concept of micro-controller and it can be used to control remote notice board.

The heart of the project is P89C52RD2BN. Here the cellular technology is considered for sending message to the notice board. The mobile used is of GSM technology.

The international roaming capability is the main strength of GSM which means it ensures seamless service for the customers. Apart from that it also enable high quality speech, digital experience, call waiting and forwarding services and freedom of using universal mobile phones. SMS is a service of GSM technology by which data can be received and send easily from one handset to another.

The message can consist of alpha numerical combination, words and numbers. SMS service is one of the widest using techniques and it is meant especially for those who have hearing or speech problems. 

The best part is that if you are outside the coverage of the GSM area then the SMS will be stored for you and once you enter the coverage area you will receive it then and there. This will also help you to be aware about the security system of your office and home.

Latest ECE Project Topic on Remote Notice Board Using GSM with SMS with Project Report

Today every advertisement is becoming digital and even the shopping malls and big shops are using this method for displays. This is an eye-catching way of grabing the attention of the consumers. You can also see that this method is being used at the bus stands and railway station for displaying the information of tickets, number of platform etc. this can also be explained as digital moving display but in case if you want to change the message or the style of display then you have to connect it with the laptop or PC.

For example if the person wants to display this content in the important areas of the city then he will have to go there along with his laptop. Then he needs to connect the display with his laptop to make the necessary changes. This is usually used by army and police sectors and it is quite helpful for them because this system will be connected with the central areas of the city and thus will enable to flash the message in 5 mins. We are focusing on designing something new that can enable to control the display from remotely.

GSM technology is being used to access the display and it one of the latest technology. This is being used in this field for the first time to create a communication between the mobile and microcontroller. 

This project will act as a remote notice board that will be connected with the modem so that when the user will desire to display any message he will just send the SMS in the format of a message to the display system. The system will further receive the message and update everything as per the instruction of the message. For undergoing this process the password is the main factor and the display will make the changes only if the password received from the sender’s mobile is matched.

Different Multipliers Using VHDL Embedded Systems Abstract

Introduction to Different Multipliers Using VHDL Embedded Systems Project:

The power consumption concern and the little occupancy are the major requirements of the fabrication of the DSP systems and other efficient performing systems. The important criteria for improvement are the enhancing speed and space of the multiplier. The speed and the space are relied on each other which mean increasing speed concludes with the more consuming space. 

We have focused to come out with a conclusion by studying more multipliers. We have studied three different multipliers differently. We found that the serial multipliers needs more power consumption compared to parallel multipliers. The project has three different multipliers called Booth Multiplier, Wallace Tree Multiplier and the Vedic Multiplier. 

The conclusion assists to select the proper multiplier for the fabrication of the systems. The multipliers are the part of the systems with presence at many places. With the analysis of the multipliers, we are able to construct a system with less power requirement and space. 

The Project  suggests for the Vedic Multiplier which is based on the Vedic multiplication method or called Sutras. The method is commonly and conventionally applied to calculate the multiplication of the two or more numbers in the decimal system. The Project also focused on the same method for the binary number system to form the algorithm which can run on digital hardware. The Vedic multiplication method used here is Urdhava Tiryabhyam for calculation of the binary system.

New Technologies Used In the Maintenance Of Underground Cables ECE Project Report

Introduction to New Technologies Used In the Maintenance Of Underground Cables Project:

Power system is divided into three parts. They are generation, transmission and distribution. Power is transmitted through overhead lines. The major power losses occur in transmitting the power from one place to another place while transmitting the power through overhead lines. Impedance and ohmic losses are the main reasons for the power loss. Growing demand of power is increasing the need of electricity. Security and flexibility is required in transmission and distribution of power in order to give efficient power in cases of unfavorable environmental conditions also.

With use of underground cables we can overcome the transmission losses like and ohmic losses upto some extent in comparison with the overhead transmission lines. With this new technology of underground cabling had the characteristics of low impedance and ohmic loss increase power transmission capacity. For long distance high power transmission high voltage underground lining is effective.

Underground lining is preferred mainly in highly populated areas, difficult planning areas and where land is not available, water ways. Unique benefits of underground cables are low transmission losses, can handle emergency power load, low maintenance cost, no electric field is emitted, less susceptible and have many advantages.

But the main disadvantage of underground cables is more expensive installation required than overhead lines. Because of this reason underground cables are restricted to the areas of densely populated and water ways areas. Other than this disadvantage we can prefer the underground cables than overhead transmission lines.

This project explains the advantages and disadvantages of the underground cables over overhead transmission lines and how to lay underground cables. Underground cables give an appropriate solution for loss less power transmission.

Intelligent Train ECE Project Report

Introduction to Intelligent Train ECE Project:

In India largest means of transportation is through railways. We have a very sophisticated and well established railway system. India’s railway network is the biggest railway network in the south Asia. There are different types of trains according to the speed and stops of the trains.

A single train can transport much number of people and goods. Even though our railway system is well defined and designed the train accidents are more frequently happening. In these train accidents we are loosing many lifes. If we can add intelligence for the trains then we may avoid most of the train accidents.

We can develop efficient methods like train signal control system using micro controller which works on signals.

In this project we can add intelligence to the train with the help of microcontroller, coordinating it with the DC motor of the train which controls the speed of the train. In this project we use GPS module to locate the train which is given as input to the PIC.

Microcontroller forms the heart of this project as it only controls all the functions. Latitude and longitude of the location given by the GPS module is  compared with data already present in the microcontroller, this helps LCD to display and announce the station names.

The main device in this project is track break detector which detects whether the track is broken or not. If the track break detector found any breaks on the track then train will stop immediately at any point and the door will be opened.

By this way using automated intelligent train we can avoid maximum number of train accidents occurring due to track breaks and can save many life’s. 

This application is a fully automated and robust system which has the advantages of less time delay, quick response and low power requirements gives a safe journey to you all.
