Distance Education System A C# Project

The project Distance Education (Learning) System is a web-based application, which deals exclusively with the online training programs for the employees of the company. It basically list-outs the available courses and time in which courses has to be completed. It even eases the task of the company to review the courses and the training done by the employees. The company can assess the performance of each employee by the online exam conducted for the course.

Only the employee of the company can access the system. The registered employee is provided with the online study material covering that particular course along with the corresponding question bank.

In our system, employees are given the flexibility to change the password and can write any type of test (level test, entry test, final test) for 3 times. If the employee is unable to complete the training with in the stipulated time, then they can request the administrator to increase the training time period. The employees can even directly write the entry test for any level. They can view the study material of the completed levels of the registered course.

Current System

The training Department of the company administers training functions and is headed by the Administrator (Training). The training is organized based on a training directive issued by the management. The administrator of the training is based on diverse media of delivery. Whereas the classroom based, instructor – led programs form the principal module of delivery. The company is also interested in promoting and developing self-learning based on distance education concept. The company has, for this purpose acquired a library of Books which are maintained on server for this purpose.

The whole process is now manually controlled. This requires intervention by the training staff at frequent intervals. It is proposed to automate this function together with the management of training function.

Proposed System

The study material available online can be in the form of documents on a server machine which can be accessed simultaneously by many users. All the permanent employees should be able to access all kinds of study material irrespective of the employee’s designation or field of expertise. No person other than the employee of the company should be able to gain access to the system.

The employee logs in to the system and selects the subject of interest. Depending on the course selected the employee is allotted a fixed amount of time during which he/she is proposed to complete the self – paced training. Once the allotted time has elapsed, the employee is not allowed to access the training program. The employee may request the Training Administrator to extend the time period for the training.

Remote Controlled Switch with Secret Code Lock Project

The project work designed with two microcontroller units is a unique one; it can be used for many applications. The main advantage of using this system is to maintain the privacy, so that un-authorized persons can not operate any electrical gadget or any iron safe (which is equipped with this system) unless they know the password. The new technology implemented in the system is, that the lock can be opened or closed automatically through remote.

The data transmitting card contains a small keyboard (which is interfaced with microcontroller) generates code, a six digit code corresponding program is prepared for microcontroller, since the program is pre-defined, pass word can not be changed. The data delivered from the controller is modulated with 38 KHz frequency produced by the timer IC, and it is transmitted via infrared LED. The controller accepts all the keys data and transmits as it is. In the receiver this data is decoded with another microcontroller, the data received through 38KHz demodulator is fed to microcontroller, the received data is compared with pre- defined program, if the data is correct then the controller energizes the relay, other wise energizes the alarm, which indicates that it received wrong code. TSOP 1738 is used as demodulator, this is a miniaturized receiver generally used for remote controlled systems, and the output of this device can be fed to controller directly for decoding.

Cyclic Redundancy Codes (CRC) For Parallel And Serial Communications

PROJECT TITLE: Cyclic Redundancy Codes (CRC) For Parallel And Serial Communications

INTRODUCTION: As it is easily imaginable, we all would like to have no errors when transmitting data over the Internet or any other media, but defects in materials, interferences and other sources can Corrupt the data, so we have to provide the communication with ways of detecting and if possible correcting those errors. It could be highly desirable to be able to check this in an ccurate and fast way, and therefore many different strategies have been developed in the early years, but almost all were based in performing some kind of mathematical operation over the bits we are transmitting. In this way, the so-called CRC was rapidly widespread as a good way of checking errors. A mathematical operation is performed over the data that is going to be sent, and the result is appended at the end of the data, thus resulting the packet that will actually be sent. At the far end of the channel, the same operation is made. If the result is the one expected then there have not been problems. Else, the data is corrupted and something will have to be made (this “something” is out of the scope of the CRC generator; it is usually an issue corresponding to the upper layers of the communication protocol).

There are various methods available for serial (example USB) and parallel (example PCI bus) communication protocols. With this motivation I would like to study various serial and parallel communications protocols needs for CRC and would like the implement the same.

Vehicle Gas Detection With Automatic Safety Warning System Project

The forklift is referred like an instrument which can lift hundreds of kilograms. Vehicle Gas Detection With Automatic Safety Warning System is a vehicle like small truck which includes two metal forks utilized to transport the cargo. The operator transports the forklift and inserts within the cargo. The forks are also called blades or tines which are constructed with steel and could transport few tons.

The most forklifts work on gasoline and still utilize diesel or gas. The terrain forklifts possess the great lifting ability and large duty tires to travel on bumpy surfaces. It is essential to proceed with safety while using the forklift.

The operators should be taken care of rear wheel steering and it is same like driving a car in reverse direction. The driver should know about the center of gravity of the operator and escape rapid turns or moving fast. Forklift should be used by licensed and expert people.

The operators possess revolutionized warehouse function which allow person to lift thousands of pounds at a time. The operator is manufactured with the help of remote technology to increase the technology for proper vision and the container is kept accurately and it would enhance safety of the operator.

Conclusion:

Vehicle Gas Detection With Automatic Safety Warning System is powered with the help of propane, gasoline, or electricity. Electric forklifts depend on batteries for the function of operator. The Gasoline forklifts are powerful and faster than electric forklifts and yet more tough to function and fuel possibly is expensive. Electric forklifts are useful for warehouse purpose since they do not produce noxious fumes.

Touch Screen Operated Liquid Dispensing System

Touch Screen Operated Liquid Dispensing System application need to handle different parameters that to be handled. This projects uses temperature sensors. Sensors are located at different points to sense temperature variations. Micro controller will handle information from sensors for further processing. Graphic LCD display is used for displaying messages.

In this process as we have to reach our requirement we assign a certain Set-Points for the sensor to monitor the temperature (Ex; Temperature-39 degrees). Based on temperature variations motor operations will set on or off.If the value from the sensor gets below the Set point, the microcontroller drives the heater ‘ON’ and starts the heating to reach the set point. This is a cyclic process. Touch screen is used to set the Set-Points for the sensor to monitor.

A typical graphics LCD system is shown in Figure 1. The system consists of a microcontroller, a LCD controller (digital-control logic, optional graphic accelerator, image buffer, gate driver), and a LCD glass.
