Each user is equipped with one can be for the RFID radio frequency identification wild card of carrying and have information such as identity, every office or every cover dwelling house dispose at least one numerical control manager (dwelling house in a plurality of rooms can be established a plurality of numerical control managers), each numerical control manager can be by setting, determine quantity (consistent with user number) and the relevant information of the subscriber card of its room or dwelling house, RFID radio frequency identification wild card is periodically launched the radiofrequency signal of encoded data modulation, the numerical control manager reads the outer card signal of radio frequency identification by card in the RFID radio frequency identification, judge through the CPU of numerical control manager I whether confirm is the user in this room, do corresponding control then.System's timing working flow process is divided following two kinds of situations:
(1) if numerical control manager (time length can according to user's needs by by key assignments) in a period of time is not read transmitting of RFID radio frequency identification wild card that this room user carries, then judge this room no one, water inlet or the water outlet of turn-offing the heat exchanger in this room by electronic or magnetic valve, and information such as the working condition of electronic or magnetic valve and room temperature value are sent data to heating and air-conditioner host energy-saving and water-saving control centre by the telecommunication circuit I;
(2) transmitting as if the RFID radio frequency identification wild card of reading this room user, judge that then there is the people in this room, the user sets the temperature in room by keyboard, liquid crystal display circuit, automatically regulate the working condition of blower fan and electronic or magnetic valve, make indoor temperature reach user's value of setting, that is: a) during heating, if temperature is lower than design temperature, then control electronic or magnetic valve connection heat exchanger, open terminal blower fan, realize that exchange heat heats up; If temperature is higher than design temperature, then close the water inlet pipe of blower fan and heat exchanger, realize that temperature descends; When b) freezing, if temperature is higher than in design temperature, then open heat exchanger and blower fan, realize cold exchange cooling; If temperature is lower than design temperature, then close heat exchanger and blower fan, realize that temperature rises; C) adjusting of indoor temperature can also make the water yield by heat exchanger change to realize by adjusting electronic or magnetic valve.No matter be in above-mentioned which kind of working condition, information such as the aperture data of electronic or magnetic valve and room temperature value can both send to heating and air-conditioner host energy-saving and water-saving control centre in real time.
For heating and air-conditioner host energy-saving and water-saving control centre, the present invention can gather heating boiler in real time, the central air conditioner system end-equipment (is electronic or magnetic valve, heat exchanger and terminal blower fan) information such as temperature in working condition and each room, and total return pipe of heating boiler or central air conditioner system main frame and total outlet pipe temperature value, calculate required boiler combustion intensity or the operating mode of central air conditioner system main frame, rotation speed of fan and each pump head flow, and pass through to boiler control system, or send out control command to the air-conditioner host controller, simultaneously by the control frequency converter, and then the variable frequency adjustment of control blower fan and water pump, the combustion intensity of heating boiler is regulated in realization in real time according to the load condition of central air conditioner system end-equipment, the lift flow of the working condition of central air conditioner system main frame and water pump, and the rotating speed of blower fan.If number of users reduces (as to the quitting time), the load of central air conditioner system end-equipment reduces, then the corresponding working strength of turning down combustion intensity, reducing the central air conditioner system main frame, reduce water pump the lift flow, turn down the rotating speed of blower fan, thereby realize energy-saving and water-saving.If there is people room quantity to increase (as to the work hours), then to control boiler and strengthen firepower, the operating mode of change air-conditioning central air conditioner system main frame improves pump head flow and rotation speed of fan, and realize being rapidly heated (or cooling) improves user's comfort level and experiences.Meanwhile, heating and air-conditioner host energy-saving and water-saving control centre regulate the air-conditioner host combustion intensity according to the temperature value of total return pipe and total outlet pipe, guarantee that frozen pipe, phenomenon that the system pipe network temperature is low excessively do not appear in the air-conditioner host system.
Automatically judge that except adopting technology of Internet of things the room has nobody, the present invention also can control the working condition of heating boiler, central air conditioner system end-equipment (being electronic or magnetic valve, heat exchanger and terminal blower fan) by following two kinds of mode of operations: the one, make a phone call to open heating boiler, central air conditioner system end-equipment in advance by the numerical control manager, and the 2nd, start the predefined time opening pattern of user by the numerical control manager.These two kinds of mode of operations all are to start terminal heating and refrigeration under unmanned situation in advance.
Use the present invention, the user only need carry RFID radio frequency identification wild card, when leaving, the user not only closes heating boiler automatically, the end-equipment of central air conditioner system (or making it be in keeping warm mode), also can gather heating boiler in real time, the working condition of each end-equipment of central air conditioner system and the temperature in each room, and total return pipe of heating boiler or central air conditioner system main frame and total outlet pipe temperature value, by calculating required boiler combustion intensity or the operating mode of central air conditioner system main frame, rotation speed of fan and each pump head flow, and pass through to boiler control system, or send out control command to the air-conditioner host controller, simultaneously by the control frequency converter, and then the variable frequency adjustment of control blower fan and water pump, the combustion intensity that heating boiler is regulated in realization in real time, the lift flow of the working condition of central air conditioner system main frame and water pump, and the rotating speed of blower fan, its energy-saving and water-saving effect is remarkable, has splendid society and economic benefit.
