摘  要

    空調(diào)器已被越來越多的家庭所應(yīng)用，它是普及的家用電器，是發(fā)展了很多年的老產(chǎn)品，其功能更是日新月異，而對其功能的提高起核心作用的是其控制系統(tǒng)。在這方面各大空調(diào)生產(chǎn)企業(yè)也進(jìn)行過很多研究，功能日臻完善�？照{(diào)器微電腦控制系統(tǒng)的任務(wù)是通過89C52的指令并根據(jù)房間的溫度、室內(nèi)熱交換器溫度、室外熱交換器溫度、壓縮機(jī)的狀態(tài)等來控制空調(diào)器的運(yùn)行過程。具體地說，就是控制壓縮機(jī)、室外風(fēng)扇、室內(nèi)風(fēng)扇、室內(nèi)風(fēng)向電機(jī)，并將設(shè)定溫度和房間實(shí)際溫度用數(shù)碼管顯示出來。另外，系統(tǒng)軟件中有過欠、壓保護(hù)壓縮機(jī)，其狀態(tài)也可通過發(fā)光二極管指示。軟件系統(tǒng)的制冷、睡眠和自動(dòng)功能子程序模塊，主要功能是根據(jù)房間溫度和設(shè)定溫度的差值，并綜合考慮其他條件，然后對壓縮機(jī)和室內(nèi)外風(fēng)扇的運(yùn)行狀態(tài)進(jìn)行智能控制。同時(shí)，在各模塊里進(jìn)行了保護(hù)處理。因此該系統(tǒng)具有制冷、睡眠、自動(dòng)3種工作模式，以及可調(diào)室內(nèi)風(fēng)速等控制功能；在定時(shí)開機(jī)時(shí)，可根據(jù)房間溫度作智能判斷，自動(dòng)調(diào)整定時(shí)開機(jī)時(shí)間，避免開機(jī)時(shí)太冷或太熱；另外對設(shè)定溫度和房間溫度兩種溫度值進(jìn)行同時(shí)顯示，完善系統(tǒng)保護(hù)功能。
微電腦空調(diào)控制系統(tǒng)主要由六部分構(gòu)成:溫度檢測、溫度控制，壓縮機(jī)、室內(nèi)、外風(fēng)扇和壓縮機(jī)控制電路，室內(nèi)風(fēng)向電機(jī)的控制，溫度指示電路，步進(jìn)電機(jī)控制電路，保護(hù)電路。

Abstract:

Air conditioner already more and more family application, it is the household appliances popularized, having developed the old products for a lot of years, its function changes with each passing day especially, and it was its control system that played a key role to the improvement of its function. Every large air conditioner manufacturing enterprise has gone on much research too in this respect, the function is becoming better and approaching perfection day by day. The task of the microcomputer control system of the air conditioner is a order of passing 89C52 and according to the temperature of the room, the temperature of the indoor heat exchanger, the states of the temperature of the outdoor heat exchanger, compressor,etc. come to control the operation course of the air conditioner. Particularly, control compressor, outdoor fan, indoor fan, indoor wind direction electrical machinery, and will establish the temperature and actual temperature of room and in charge of the number to show. In addition, owe, press and protect the compressor in the systems soft ware, its state can be pointed out through LED. Refrigeration, sleep and automatic function subprogram module of the software system, the main function is according to the temperature of the room and difference of establishing temperature, and consider other conditions synthetically, then carry on intellectual control to the operation states of the compressor and internal and external fan of room. Meanwhile, protected dealing with in every module. So this system has refrigeration, sleep, 3 kinds of automatic work patterns, and the adjustable indoor wind speed,etc. control the function; While starting the machine regularly, can do intelligence and judge, adjust the time of starting the machine regularly automatically according to the temperature of the room, it is too cold or too hot while avoiding starting the machine; Show at the same time in establishing two kinds of temperature value of temperature and room temperature in addition, the perfection system protects the function.
The air conditioner control system of the microcomputer is formed by six parts mainly: Temperature measuring, temperature control, compressor, indoor and outdoor fan and compressor control circuit, the control of the electrical machinery of indoor wind direction, temperature points out the circuit, walk into the control circuit of electrical machinery, protect the circuit.
