Background technology
Along with development of modernization, consumption to various renewable and non-renewable resources also increases thereupon, power-saving technology is arisen at the historic moment, the service efficiency of for example resource circulation utilization, the raising energy etc., but these The Application of Technology need user's cooperation to realize.In some public arenas, owing to lack supervision and management, the user may have a mind to or abuse water, electricity or other public resources unintentionally, has both wasted the energy, can influence the energy-conservation enthusiasm of people again.
In order to limit this waste to a certain extent, occurred controlling the mode of waste now, thereby reached purpose of energy saving by charging.Just announced a kind of like this water saving fixtures in Chinese patent 03121966, this water saving fixtures comprise that IC supplements manager and water saving managing device with money, and wherein IC supplements manager with money and can carry out detailed setting to billing function, and water saving managing device is controlled water outlet.These water saving fixtures adopt non-contact IC card to pay the fees, and when IC-card was placed into the IC-card card carrying area, IC-card was supplemented manager with money and can be calculated the remaining sum in the IC-card and show that IC supplements manager with money according to the corresponding amount of money in the time deduction IC-card of water outlet.When not having remaining sum in the IC-card, water saving managing device can be controlled and stop water outlet.
The mode that above-mentioned water saving fixtures charge is charged according to time; its water consumption equals the water outlet time and multiply by the flow velocity of water; in order to control water consumption; need to guarantee the constant of water flow velocity; and water flow velocity can change along with the size of boiler pressure usually; therefore calculate the mode that water consumption is collected corresponding expense by the time, still have obvious defects, precision and accuracy are not high.In addition, this energy saver all is private energy-saving apparatus usually, promptly can only control poor expandability at certain concrete controlling object.
