The Application Of The Voice And Remote Control In The Automotive Air Conditioning System

The automotive air conditioning system realizes the function of the temperature control, air purification and ventilation, etc. It aims to provide a comfortable travel condition for the passengers. The most of the operation is done manually in the existing automobile air conditioning system. It is not only inconvenient for the drivers to control the air conditioning in the process of driving but also reducing the safety by distracting. In the case of the bad weather, people feel hot or cold when they just enter the automotive and have poor comfort.The thesis takes the automotive air conditioning as research object and a kind of scheme that the voice and remote control is used in automotive air conditioning system is proposed. The voice operation for the automotive air conditioning could be achieved by the combination of the voice recognition module and the control module, so as to solve the inconvenience of manual operation. While the remote operation of the automotive air conditioning could be realized by the remote communication module and the control module. Users can remotely operate the automotive air conditioning according to the demand and it adjusts the interior air temperature of the automotive according to the setting temperature by the user and the inside and outside air environment of the automotive. Consequently, people have an appropriate air environment when they just enter the car and the comfort is improved. Through the design of the CAN bus, the system could be able to communicate with the other control systems in the car and complete control, therefore, the practicability of the system is enhanced;Firstly, the control flow of the entire system is completed according to the characteristics and the control requirements of the automobile air conditioning. Secondly, the main control module, the voice recognition module and the remote communication module are selected then the hardware and software design of the automotive air conditioning system are completed. The circuit diagram of the entire system and PCB board are accomplished in hardware design. And the initialization of the automobile air conditioning system, the control of the main program, the communication program and the driver of all modules are completed in software design. Finally, the testing and analysis of the automotive air conditioning system are finished.The debugging of the design of the automotive air conditioning system is completed by software and hardware platform. The hardware circuits and software programs of the control system are simulated by the software platform. The tests of the control system are actually accomplished by the material hardware platform. The whole process is divided into the test of the function of voice recognition module and the test of the remote control. The test shows that the voice recognition module and the remote communication module with the main control module could achieve the functions of the voice control and the remote control, thus meeting the requirement of the research project.
