Based On GPS And GPRS Car Alarm System Sotfware Design

With the people’s material living standards improve, the family car has entered theVolkswagen ordinary family, but with the development of science, technology with thedevelopment of automobile theft, let people off guard, so how to develop effective anti-theftdevices for cars have become an important issue. Based on GPS and GPRS car alarm systemis the integrated GPS technology and GPRS technology of high-tech system is the idealsolution for car security solution. Including GPRS communication networks, geographicinformation system terminals, electronic display, control terminal, the host computer. VehicleGPS mobile unit location data transmitted vehicle information, vehicle information and alarmhandling scheduling, real-time display the current exact location of the vehicle, so they caneasily achieve the vehicle scheduling, monitoring, monitoring center receives, instructions,etc., but the GPRS wireless communication network by the equipment installed in the vehiclesends various control commands for remote control of the vehicle.Car alarm system is composed of two car terminal and monitoring center portion of acombination of software design, software design need to separate these two parts of thedesign. In addition to the normal vehicle terminal communication function, but also that thecontrol center is also real-time vehicle location data, operating status and alarm information.Vehicle terminal through the GPS receiving antenna receives GPS satellite positioningsignals transmitted CPU processing, calculate the vehicle’s date, latitude, longitude, direction,and other location data. Master controller CPU core processor sends to the receiver theposition information, the position information is displayed on the information display frameon the monitor, and control the GPRS module to send and receive short messages.This car alarm system design introduces the overall structure and operating principle, aswell as the software development process faced some technical difficulties during theoperation using the development tools and operating platform, detailing the hardware andsoftware of the system as a whole design idea, and each functional module design. The entire system development and design process, fully taking into account thefeasibility, accuracy, stability and reliability, simple operation, suitable for use as a vehiclemounted equipment.
