Abstract
The heating management information control system comprises the heating control system, the energy sources evaluation management system and the heating charge management system. The heating charge management system provides the user' heating information for the heating control system and the energy sources evaluation management system. With the user' heating information being processed, the heating control system sends the command out to control the heating. Meanwhile, the heating information is transferred to the energy sources evaluation management system, which evaluates, manages and dispatches overall system. The invention is applicable to central heating supply of city infrastructure.
Description
Technical field the invention belongs to computer management control technology field.
The background technology central heating is as urban infrastructure, has energy savings, reduces environmental pollution, the advantage of aspect such as the quality of improving the people's livelihood, and central heating is the mode that generally adopts.The central heating system of developed countries is dynamic variable flow system, and it is regulated and the control technology advanced person, and control device is perfect, the equipment quality height.It is the trend of countries in the world development that central heating is chargeed by heat.
Can regulate indoor temperature as required in order to measure heat and user, each user will install calorimeter, and on each heating radiator temperature-sensing valve is installed, and the user will regulate temperature-sensing valve according to the demand of oneself and control indoor temperature like this.At present, American-European countries is following three kinds by the method that family metering heat uses substantially: (1) is directly measured the user and use heat from heating system; (2) determine user's the heat of using by the heat dissipation capacity of measuring user's heat dissipation equipment; (3) determine user's the heat of using by the thermal load of measuring the user.These three kinds of methods all need high performance hot measuring instrument.Aspect temperature control and hot measuring products, external major company such as Danfoss, Honeywell, Siemens, Schlumberger etc. have very outstanding product.Domestic production enterprise enters the starting stage comprehensively, and the development job development of temperature control and hot measuring products is very fast.Wherein the intelligent probe formula flowmeter of professor Xu Xiangdong of Tsing-Hua University research and development has precision height, good reliability, highly sensitive, intelligent, advantage that usable range is wide, is one of domestic and international combination property optimal flow rate surveying instrument through facts have proved.
Meterage can be transferred the enthusiasm of heat supply and user two aspects, and then promotes energy-conservation.The user can regulate indoor temperature as required and change flow, after but the multi-user regulates the flow of oneself in the presence of all, the flow of whole heating network and heating load also will change thereupon, can't predict and control and the variation of this flow and heating load is heating enterprise and thermal source place.Heating enterprise and thermal source place are then by initiatively becoming passive suitable follower, this variation must bring new problem, how to regulate such as the heating network flow? under the prerequisite that guarantees user's heating quality, could how heating enterprise moves be reduced operating cost, increase economic efficiency? there are the heat supply control and heating charge two cover systems of separation in domestic and international now cogeneration plant more, so just isolate the contact between heat supply control and charge, made the heat supply of cogeneration plant can not well react its economic benefit.For the friend's exhibition that adapts to enterprise's breathization, the modernization that realizes ladder of management, need effective combination of heat supply network computer controlled automatic and heating charging.We just under this background the heating management infosystem to cogeneration plant study, to solve the centralized management problem carried out in heat supply control and heating charge, and to adapt to the regulating and controlling problem that adopts heating system behind the meterage.
It is feasible, economical and practical that summary of the invention the purpose of this invention is to provide a kind of advanced person, guarantee heating network can reliability service, satisfy user's heat supply requirement, can operational management, economic benefit energy-efficient, that make heating enterprise a heating management management information system that significantly improves be arranged all again simultaneously.
