Design And Implementation Of Communication Module For Car Air-conditioning Remote Control System Based On FPGA

With the rapid development of the national economy, the car has entered thelives of ordinary people, who have high requirements on the performance of the car.The maximum temperature of Northern China summer is up to above35°C, Theinterior temperature of the Vehicles under the hot sun will be higher. therefore, peoplewill generally wait the temperature decreases outside the car before driving. Toresolve this problem, I find a solution that about remote control air conditioningsystem based on FPGA. Owners can take advantage of SMS to open the car’s airconditioning system in advance, so that the car can make a suitable temperature,creating a comfortable environment. With the continuous development of automobileelectronic technology, electronic devices in the car will be more and more, Highlyintegrated digital circuits is one way to solve this problem, It is a complete system ona single chip, which Generally include system-on-chip control logic module,microprocessor, memory, or memory control module, a variety of interfaces andexternal communication protocol module and so on, However, FPGA internal canintegrated CPU, DSP, and a variety of interface control module, FPGA is no doubtthat the ideal vector.This article make Cyclone series EP1C3T144C8as the core chip, I design theremote control communication module of automotive air conditioning systems basedon FPGA, Owners can sent SMS commands of the temperature to the car GSMmodule (TC35i) in use of the existing communications network (GSM), theinstruction will pass through the serial port of TC35i, and it will process instructions.After processing, it can send the instruction to the vehicle CAN bus to achieve controlof the car air-conditioning system.This thesis completes the following work: First, set the SF-EP1C chip as theprototype, I design the hardware system of the TC35i and FPGA communication, inthis system, using the serial port of the PC analog TC35i achieve the communication of EP1C3T144C8,4digital tube analog Car LED display the target temperature;Secondly, I design the communication code of TC35i and EP1C3T144C8,EP1C3T144C8automotive CAN bus; Thirdly, make use of the Verilog HDLhardware description language to write the corresponding module, I make functionalsimulation of the various functional modules and Board-level debugging, to makesure that is right.
