Description
Affiliated technical field
The utility model relates to heating and computer, single-chip microcomputer and programmable controller controls field.
Background technology
At annual heating season, people will drop into a large amount of financial resources, material resources solve the heating problem, the energy of heating usefulness mainly is coal, oil, non-renewable energy resources such as natural gas, and consumption is very big, under the situation of energy scarcity and rise in price, heat cost is more and more higher, while coal, oil, natural gas produces a large amount of dusts in combustion process, harmful substance such as carbon dioxide and sulfur dioxide, the pollution of air and the discharging of a large amount of greenhouse gases have been caused, thereby cause the heating of northern city can suck the particle severe overweight in the air season, air quality obviously descends.
At present; in heating installation design and installation process; every building; each unit; advancing of every group of radiator; delivery port all has a machinery valve; its main application is control heat supply and convenient for maintaining; because the heater control valve door of every building generally all is installed in below the outdoor ground; usually also have cement cover board to cover above the valve; perhaps be installed in basement; the position that corner etc. are remote; and the normal installation site of heater control valve gate open is on the low side in the room; have even quilt is fitted up wall group inside; open very inconvenient and hard; substantially always be in normally open during heating; use once in a while when having only maintenance, by-pass valve control does not play the effect of control heating substantially.
In the heating process, no matter be office building, office building, dormitory building, or hotel, restaurant; No matter be the heating of concentrated supply of heating in the city or collective of unit; Also whether the someone works, lives regardless of the room, radiator is installed to each room substantially, one day 24 hours supply heating installation, also to guarantee certain indoor temperature simultaneously, and the time that office building, the actual people of having of office are worked have only 8 hours daytimes, unmanned again life during the family working, the occupancy rate of hotel is not absolutely ... sometimes also there is the phenomenon of windowing and dispelling the heat because indoor temperature is too high, not only cause the significant wastage of manpower, fund and the energy, and caused the pollution of air and the discharging of a large amount of greenhouse gases.
What and climate temperature of the height of heating cost and heating consumes energy, heating duration length, the heat exchange speed, the heating hot water temperature, heating area, hot water flow is relevant with factors such as flow velocitys, wherein, climate temperature is the natural cause that can't change, the heating duration length of whole heating season is determined by natural cause, the speed of exchange heat removes outside the Pass material with radiator has, with the hot water temperature, hot water flow is relevant with flow velocity and environment temperature on every side, the hot water temperature and the environment temperature temperature difference are big more, exchange heat is fast more, the temperature difference is more little, and exchange heat is slow more; Flow is big more, flow velocity is fast more, exchange heat is many more, flow is more little, flow velocity is slow more, exchange heat is few more, therefore science is controlled heating duration, heating temperature, heating area, hot water flow and flow velocity well, can reduce heating cost greatly, reduce energy resource consumption, thereby reduce the discharging of air pollution and greenhouse gases.
Along with microelectric technique, singlechip technology and development of computer and application, automation is controlled at all trades and professions and is developed and utilizes, especially PROGRESS IN PROGRAMMABLE CONTROLLER and application, for automation control provides powerful, simple operation, use flexibly and the control module of stable performance.
Programmable controller mainly is made up of CPU, memory and input/output interface, programmable device four parts, have functions such as logic control, timing controlled, counting control, stepping control, data processing, circuit controls and the networking of communicating by letter, have combination, programming, flexible operation, volume is little, low in energy consumption, interface power is big during input and output, the characteristic that antijamming capability is strong and reliable and stable has characteristics easy for installation, easy to use, easy to maintenance.
Summary of the invention
Be regardless of the indoor people of having no one in the present heating process in order to overcome, it is useful useless to be regardless of heating, all keep continuing heating and can't regulating heating temperature automatically in one day 24 hours, cause the energy to waste in a large number, the deficiency of a large amount of dischargings of air pollution and greenhouse gases, the utility model provides a kind of automatic control heating installation, this device can not only be controlled automatically and when heat, when do not heat, and can control heating temperature and the warming temperature between heating period not between heating period automatically, prevent between heating period indoor temperature cross low or too high and not between heating period indoor temperature low excessively, prevent that heating pipe network from freezing and bursting by freezing, satisfy special heating demand in particular cases simultaneously.
The utility model is made up of casing, power supply, programmable controller, human-computer dialogue display screen, stepper motor driving circuit, step motor control valve, temperature sensor and analog to digital conversion circuit.Wherein, programmable controller is the control maincenter of whole device, the storage program information, determine heating duration, control heating process is regulated heating temperature, receive temperature sensor and human-computer dialogue information by input interface, send control signal by output interface, drive stepper motor driving circuit work, thereby the unlatching of control step motor-driven valve is with closed; Temperature sensor detects the entery and delivery port temperature of controlled part in the heating pipe network and converts the input interface that data signal is sent to programmable controller to by analog to digital conversion circuit.The human-computer dialogue display screen is used for human-computer dialogue, and relevant parameter is set, and is controlled by programmable controller, the time that shows date simultaneously, entery and delivery port temperature and duty.
The utility model is with one in the water inlet by-pass valve control of every building, each unit or every group of radiator in the present heating pipe network or delivery port by-pass valve control repacking or add and dress up controllable stepper motor driven valve door.
