Said system also possesses the functions of picture display, report printing, data storage and inquiry, so that it is favourable for management of air conditioner.
Description
The present invention relates to a kind of control system of combined type air conditioner.
Relevant by retrieval patent documentation does not retrieve the combined type air conditioner control system identical with structure of the present invention at present as yet.Along with improving constantly of development of modern industry and living standard, assembled air-conditioner is widely used in the place of having relatively high expectations to air ambient in industry such as electric power, electronics, chemical fibre, weaving and office block, hotel etc.Traditional assembled air-conditioner generally adopts electrical equipment control and instrument to control to realize the purpose of controlling.Electrical equipment control is not because its precision is not high, and natural air temperature, humidity constantly change, and needs often to regulate.Though adopt instrument control can reach certain requirement, but generally parameter is regulated and is formed single loop control one to one, and the parameter of assembled air-conditioner itself, as temperature, humidity and spray, cold, the heating of table, humidification, air quantity size etc. certain correlative connection is arranged all, how to make the control that is coupled between each parameter, improve control accuracy, for a long time, people are concentrating on studies.
The objective of the invention is to provide a kind of microcomputer and air-conditioning technical are combined together, realize intelligent optimization control, reach the microcomputer self-control system for combined type air conditioner of extension set control, centralized management.
Technical characterictic of the present invention is: on the basis of considering raising control accuracy and reliability, designed the microcomputer self-control system for combined type air conditioner of being made up of automatic control mainframe, Sensor section, executing agency.It is characterized in that: described automatic control mainframe is provided with the system simulation figure of each section actual condition in the demonstration air-conditioning system running; Described automatic control mainframe is provided with the main frame part, and is furnished with the function of artificial setting relevant controlling parameters; Described automatic control mainframe also is provided with manual control system: the main frame in the described automatic control mainframe partly adopts STD5092-3 bus type industrial computer.Combined type air conditioner is made up of air return section, fillter section, surface cooling section, humidifier section, bringing-up section, air supply section; The operation principle of combined type air conditioner is: when environment temperature was lower than design temperature, bringing-up section work improved wind pushing temperature; When environment temperature was higher than design temperature, surface cooling section work reduced wind pushing temperature; When air-supply humidity was lower than setting humidity, humidifier section was heated; When ambient humidity was higher than setting humidity, by surface cooling section, bringing-up section, cooperation was dried and is carried out humidity regulation; Fillter section is used for improving the clean quiet degree of air-supply, and sets the size of adjusting motor speed with the control air output according to air quantity.The operation principle of microcomputer automatic control is: signals such as tested, controlled temperature, humidity, air pressure, become 0～10MA signal or switching signal by sensor, give A/D converter through the I/V circuit conversion, CPU will patrol and examine each signal, calculate, compare through digital filtering, change parameter PID etc., aperture size in conjunction with each valve position feedback signal, provide control signal corresponding, remove to control corresponding motor-driven valve or pneumatic operated valve by 8 road D/A converters or switching value output control signal, to realize best automatic adjusting and control.
Advantage of the present invention is: main frame partly adopts STD5092-3 bus type industrial computer, and combines with the I and II watchdog technique, thereby has improved the reliability of whole system; Owing to systems soft ware uses fuzzy control and adaptive mode assembled air-conditioner is controlled, thereby can be realized that operating mode automaticallyes switch according to the alternation of the seasons, move automatically, need not the effect of manual operation; Picture is colored to be shown owing to system has, all kinds of report printings, and Various types of data is stored, handles, is inquired about, thereby has made things convenient for the management of air conditioner and system.
