RF IC card heating charging energy-saving control valve

Abstract

The invention relates to a radio IC card heating account energy-saving control valve, wherein it comprises a steering positioning circuit board, a main control circuit board, an antenna circuit board, a lithium-thionyl battery, a LCD liquid crystal display, a protective frame and a valve; the protective frame has buttons to read and write the radio IC card, control the valve, display left amount and display the state of valve. The invention can use one card to charge several valves, and instruct the switch state of valve.

Description

technical field [0001] The invention relates to a billing energy-saving device for a building heating system, in particular to a ball valve device system for prepayment with a radio frequency IC card. Background technique [0002] my country has a large population and relatively insufficient resources. Per capita resources are less than half of the world's average level, and per capita energy consumption is only 55% of the world's average level. At the same time, greenhouse gas emissions are the second largest in the world. The energy consumption per unit building area in my country is more than 2 to 3 times that of developed countries. Saving energy and reducing environmental pollution have become the key to the sustainable development of my country's national economy. Since the beginning of this year, the Chinese government has put forward the call of "establishing a resource-saving national economic system and a resource-saving society", and will include it in the natio...

Problems solved by technology

[0004] Ordinary mechanical heat meters, as a household metering device for heating and heating, have encountered four difficult problems in actual use: one is the blockage caused by the poor water quality of the heating system, and the other is the lack of charging standards. The third is that the society does not save energy and the family does not save money because of the mere measurement without control function, and the fourth is the difficulty in charging the property management department due to malicious arrears.

There are three main disadvantages of this product: first, the frequency is low and the card reading speed is slow; second, the center frequency is easily shifted by the environment, and the reliability of card reading is deteriorated, and the performance is unstable; third, the memory capacity is small, Poor versatility, it is difficult to realize water, electricity, gas, heat card

Moreover, such products do not comply with the "Common Technical Standards for Construction IC Cards"; on the status of the valve, there is no indication of the current status of the valve, and the user does not know whether the valve is open or closed, resulting in blind management and use; On the other hand, it is not possible to manually switch the valve, which has no energy-saving effect, and cannot achieve the unity of prepayment, national energy conservation and family savings; in terms of antifreeze and heat preservation, there is no water supply flow port reserved enough to prevent freezing, which will easily cause the household heating system to freeze. Bad consequences; In terms of reliability, there is no ability to prevent scale and debris blockage
