Abstract
The utility model which discloses an IC card intelligent calorimeter belongs to a technical field of the manufacturing of the instruments and meters, comprising a temperature sensor, an analog signal conditioner, a microprocessor, a flow sensor, a liquid crystal display device, and an intelligent calorimeter composed of a non-contact IC card and a valve; wherein, the temperature sensor is connected with the microprocessor by the analog signal conditioner, and the microprocessor is respectively connected with the flow sensor, the liquid crystal display device and the valve. The temperature sensor loads the collected heat signal on the analog signal conditioner, when the utility model works, and the amplification, the filtration and the self-calibration are completed. The microprocessor which reads the temperature data from the analog signal conditioner receives the signal from the flow sensor, the signal processed is loaded on the liquid crystal display device, and is displayed. The utility model has only two chips, and the two chips are the analog signal conditioner and the microprocessor; the circuit is simple, and the reliability of the system is improved, with the reduction of the cost of the meter.
Description
Technical field
The utility model belongs to instrument and meter manufacturing technology field.It is a kind of heat measuring meter that is used for central heating.
Background technology
At present, the supply of coal gas, water, electricity all is that consumption is consistent with charge by the table meterage, as the heat of another kind of commodity, and the mode that is but still keeping the welfare heating or charging by area.Along with development of market economy, the problem that exposes is more and more, takes over difficulty as uneven in temperature, energy dissipation and heat expense.Existing calorimeter complex structure costs an arm and a leg, and the quality instability is difficult to work reliably and with long-term.
Summary of the invention
The technical problems to be solved in the utility model is that to disclose a kind of cost low, stable performance, intelligent calorimeter reliably.
The scheme that the utility model is dealt with problems is to adopt temperature sensor, the analog signal conditioner device, microprocessor, flow sensor, LCD, non-contact IC card and valve constitute intelligent calorimeter, wherein temperature sensor connects microprocessor by the analog signal conditioner device, microprocessor is the connection traffic sensor respectively, LCD and valve, the output terminal of analog signal conditioner device connects 2 of microprocessor, 3 pin, the output terminal of flow sensor connects 50 of microprocessor, 51,52 pin, the control end of valve connects 40 of microprocessor, 41 pin, 12 of microprocessor, 13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,36,37,38,39 pin connect 1 of LCD respectively, 2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26 pin.During work, temperature sensor is sent the heat signal of gathering into the analog signal conditioner device, finish amplification, filtering and self calibration, microprocessor is reading temperature data from the analog signal conditioner device, and receives the signal from flow sensor, through integral operation, obtain heat accumulative, send into liquid crystal display displays then, non-contact IC card is used for the instrument initialization, calibrates, checks meter, when being used, can realize that Prepayment Heat Meter is supplemented with money and quantitatively control with valve.
The utility model only contains two chip blocks, i.e. analog signal conditioner device and microprocessor, and circuit is simple, has obviously improved the reliability of system, has reduced the instrument cost simultaneously.
