A PROJECT ON GPS BASED VEHICLE MONITORING SYSTEM: GPS SYSTEMS INDIA (No of pages: 81)
INTRODUCTION ABOUT PROJECT
VEHICLE TRACKING SYSTEM
RESULT AND CONCLUSION
GPS (Global Positioning System) is the technology most commonly used for vehicle tracking these days. There are also other variants of AVL (Automatic Vehicle Location) that enable easy location of vehicles. The GPS modules with their satellite linked positioning technique make easy and accurate location of the vehicle possible. The information can be viewed on electronic maps that are connected to the Internet or otherwise supported by specialized software. Advanced GPS modules may also have cellular or satellite transmitters that communicate with remote users apart from the central station from where the tracking is done. These systems were originally developed by the government for defense purposes. The satellite part is thus available to civilians and commercial users free of cost. All the user needs to do is install the appropriate devices for sending out and receiving signals. This makes GPS an inexpensive technology.
- To design a system that gives the directions to reach a place, the user wishes to and the system also functions as an obstacle detecting vehicle.
- To locate the position of the any object or person attached with GPS receiver
- To provide a solution to avoid car stolen in the lower cost than advance security car system (GPS).
When the mobile phone receives the SMS messages that are parts of a concatenated SMS message, it combines them to one message automatically. The correct behavior should be: when the mobile phone receives the SMS messages that are parts of a concatenated SMS message, it forwards them to the computer without combining them.
- Many mobile phone models cannot be used with a computer to receive MMS messages. Because when they receive a MMS notification, they handle it automatically instead of forwarding it to the computer.
- A mobile phone may not support some AT commands, command parameters and parameter values. For example, some mobile phones do not support the sending and receiving of SMS messages in text mode. So, the AT command “AT+CMGF=1” (it instructs the mobile phone to use text mode) will cause an error message to be returned. Usually GSM/GPRS modems support a more complete set of AT commands than mobile phones.
1888: Friedrich Reinitzer (1858–1927) discovers the liquid crystalline nature of cholesterol extracted from carrots (that is, two melting points and generation of colours) and published his findings at a meeting of the Vienna Chemical Society on May 3, 1888 (F. Reinitzer: Beiträge zur Kenntniss des Cholesterins, Monatshefte für Chemie (Wien) 9, 421-441 (1888)).
1962: Richard Williams of RCA found that liquid crystals had some interesting electro-optic characteristics and he realized an electro-optical effect by generating stripe-patterns in a thin layer of liquid crystal material by the application of a voltage. This effect is based on an electro-hydrodynamic instability forming what is now called “Williams domains” inside the liquid crystal.
1964: George H. Heilmeier, then working in the RCA laboratories on the effect discovered by Williams achieved the switching of colours by field-induced realignment of dichroic dyes in a homeotropically oriented liquid crystal. Practical problems with this new electro-optical effect made Heilmeier continue to work on scattering effects in liquid crystals and finally the achievement of the first operational liquid crystal display based on what he called the dynamic scattering mode (DSM). Application of a voltage to a DSM display switches the initially clear transparent liquid crystal layer into a milky turbid state. DSM displays could be operated in transmissive and in reflective mode but they required a considerable current to flow for their operation. George H. Heilmeier was inducted in the National Inventors Hall of Fame and credited with the invention of LCD.
1960s: Pioneering work on liquid crystals was undertaken in the late 1960s by the UK’s Royal Radar Establishment at Malvern, England. The team at RRE supported ongoing work by George Gray and his team at the University of Hull who ultimately discovered the cyanobiphenyl liquid crystals (which had correct stability and temperature properties for application in LCDs).
1970: On December 4, 1970, the twisted nematic field effect in liquid crystals was filed for patent by Hoffmann-LaRoche in Switzerland, (Swiss patent No. 532 261) with Wolfgang Helfrich and Martin Schadt (then working for the Central Research Laboratories) listed as inventors.
METHODOLOGY TO BE USED:
Research methodology is a way to systematically solve the research problem. it may be understood as a science of studying how research is done scientifically. So, the research methodology not only talks about the research methods but also considers the logic behind the method used in the context of the research study.
Descriptive research will be used in this study because it will ensure the minimization of bias and maximization of reliability of data collection. The researcher had to use fact and information already available through financial statements of earlier years and analyze these to make critical evaluation of the available material. Hence by making the type of the research conducted to be both Descriptive and Analytical in nature.
RADIO FREQUENCY (RF) MODULE TO BE USED:
- Automatic switching between TX and RX mode.
- FSK technology, half duplex mode, robust to interference
- 4 GHz band, no need to apply frequency usage license
- Protocol translation is self controlled easy to use
- High sensitivity ,reliable transmission range
- Standard UART interface,TTL(3-5)logic level.
- Sensor networks/data collections
- Wireless metering
- Access control/identify discrimination
- IT home appliance
- Smart house products/security systems
- Remote control/remote measurement system
- Weather stations.
DATA COLLECTION METHOD:
Primary data is the new or fresh data would be collected from the respondents through structured scheduled questionnaire.
Secondary data will be collected through the mentioned ways.
Magazines and Journals
Text books published on Human Resource Management.
Websites and Search engines
Any study requires information about the elements of the population which is common to most of the units and the conclusions which can be generalized to the entire population. The process of extracting some units, or a sample, from the population is termed as sampling.
Types of Sampling
The sampling would be used two types of sampling technique
- Probability Sampling
- Non-Probability Sampling
ANALYTICAL TOOLS :
- The study employs the following analytical tools:
- Comparative statement.
- Common Size Statement.
- Trend Percentage.
- Ratio Analysis.
SAMPLE SIZE: 100 employees
POPULATION: All the employees of the company
