However, this method has the following disadvantages: first, because the door of the pipe well is usually locked, when a resident needs to recharge the valve, the heat supply unit must send someone to open the door of the pipe well, which is very inconvenient; Second, the heating unit cannot intuitively understand the opening and closing status of the valve of a certain household. When the valve of a certain household fails to close, the heating unit cannot know in time, which will cause heat loss to the heating unit; When the remaining calorific value is insufficient, residents cannot know in time, which brings inconvenience to users
The concentrator is a bridge for data transmission, which not only transmits data to the main control center, but also executes the control instructions sent by the main control center; however, due to factors such as interference and transmission distance of the GPRS signal during transmission, the communication will be unstable. When the concentrator reports data to the main control center, there will be interruptions, delays, and even errors. Sometimes errors will occur when executing the instructions of the main control center. For example, the control of the thermal valve often fails, and it is easy to cause large-scale operation failures. Both for heating units and households, there may be losses

Description
Technical field [0001] The invention relates to the field of automatic meter reading and charging management and control of a heating system, in particular to an IC card control terminal of a building concentrator of a heating system. Background technique [0002] In recent years, with the continuous advancement of national energy conservation and emission reduction work, new buildings in northern my country have basically installed heat meters, and the heat metering and renovation of existing buildings has also been vigorously promoted. The mode of charging heating fee is changed to charge according to the measured value of the heat meter. For residents, more heat is used to pay more, and less heat is used to pay less, which saves costs; for heating units, it saves energy consumption and benefits the country and the people. But at the same time it also brings a problem, that is, the difficulty of charging. [0003] At present, the heating company can only copy the household's hea...
