哈尔滨工业大学工程硕士学位论文AbstractAutomobile air-condition system is an important part of the improving ofcomfort degree,and the air-condition controller is the core of performing ofwhole air-condition system.To improve the comfort degree of auto,automanufacturers equip super automatic auto air-condition for their productions oneafter another.Nowadays,however,foreign manufacturers have monopolized themarket and high-level technology,and the national manufacturers have toproduce the low-level electronic air-condition controller or manual air-conditioncontroller.Now national products of air-condition controller are far from foreignnot only on market but also technology.Aiming at the situation that the research technique of domestic auto air-condition controller is lower,the thesis put forward to design a completelyautomatic air-condition controller with the much sensors signal import useing theintelligent control technique.The kind of controller exceed the now availablehome-made auto air-condition controller produce far away not only in the servicecapacity but also in the complex degree and intelligentization degree,and catchup with foreign produce in the technique.The auto air-condition controllerimprove the defect such as little sensors can't get the exact environment dataand consumes much energy of past produces.Using the high performancemicroprocessor,collecting five signal of sensor,analyzing them inside themicroprocessor and applying the neural network technique and the fuzzy controltechnique design an intelligent controller,the kind of controller achieves thebetter control effect to executive body such as ventilations door,blast engine,compressor and so on,and prompt the various index of auto such as energyconsumption and acceleration performance.Combining the design requirement the paper design the hardware andsoftware of the kind of air-condition controller.The SOFTTUNE 89F538 is thecore microprocessor of hardware circuit and the software adopt C's programminglanguage.The paper discussed the test means of software,the result of test showsthat the software meet the demand completely.Now,the kind of auto air-condition controller have been tested by means of
