Abstract

A calorimeter for the heating in the winter is composed of mechanical unit, sensor unit and circuit unit. It features that the software for the CPU in circuit unit has a program to calculate out the heating free according to heated area, price and the ratio of area to caloricity.

Description

A kind of calorimeter

Affiliated field:

The present invention relates to a kind of device of measuring heat, disclose specifically that a kind of to be used for metering user in the central heating net actual in heat and the actual calorimeter that should hand over heat expense.

Background technology:

Calorimeter on the present China market, no matter ordinary hot scale or Prepayment Heat Meter, no matter be monoblock type heat or combined hot scale, the principle of its calorimetry mostly meets " calorimeter " standard of national urban construction portion issue, both standard C J/T 120-2000, the shown measurement result of these calorimeters is the unit of heat or surplus heat (surplus heat two forward purchasing heats one are used heat) both, W.h or GJ, KW.h, if according to other measuring instrument (as water meter, gas meter) charging method calculates, the heat expense should be: the heat that calorimeter shows multiply by caloric value (both each GJ or how many yuans of KW.h), but in fact this is not the receivable hot expense of heat supply department.

Summary of the invention:

Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, makes charge more reasonable and provide a kind of, and can directly demonstrate the receivable heat expense calorimeter of heat supply department.

Technical scheme of the present invention is: a kind of calorimeter, comprise mechanical part, Sensor section and circuit part, Sensor section comprises temperature sensor and flow sensor, circuit part comprises an IC-card receiving trap, a singlechip CPU and a peripheral circuit thereof that contains specific software, software in the singlechip CPU receives the temperature and the flow of synchronous acquisition from temperature sensor and flow sensor, carrying out accumulation of heat calculates and revises, after carrying out the heat accumulation calculating, by the parameter display buffer, on display, show heat, hot expense; It is characterized in that: also comprise in the software among the above-mentioned CPU:

One goes out area heat expense by input heating area, area heat unit price, these calculation of parameter of area heat ratio and by input measuring heat unit price, these parameters of measuring heat charge proportion and go out the program of metering heat expense in conjunction with the above-mentioned cummulative metering heat numerical evaluation that calculates;

One by the hot expense of the hot expense=area of formula+measure hot expense, calculates the program of user's actual heat consumption and the actual expense that should hand over;

For calorimeter with the forward purchasing of IC-card form, also comprise one in the software among the above-mentioned CPU after calculating that the user is actual and should paying dues, by the formula delayed heat expense=forward purchased heat fee-actual program that should hand over the heat expense, if the delayed heat expense equals 0, then by the heat supply of single-chip microcomputer instruction control valve breakdown, if the delayed heat expense is not equal to 0, then delayed heat expense, actual these parameters of heat expense of should handing over are input to the display buffer, shown:

Advantage of the present invention is: 1, overcome the irrationality of original heat expense metering, determined that with the hot expense of hot expense=area+metering heat expense be the new model of heat expense metering method, made charge more reasonable.2, can directly demonstrate the receivable hot expense of heat supply department, improve the work efficiency of charge.

Embodiment:

As shown in Figure 1, 2: a kind of calorimeter, comprise mechanical part, Sensor section and circuit part, Sensor section comprises temperature sensor and flowmeter, circuit part comprises circuit board, the display in housing, the housing, and circuit board comprises the singlechip CPU, storer and the peripheral circuit thereof that contain specific software.Circuit part enters step 1 after energized and initialization:

After input heating area, area heat unit price, area heat ratio, measuring heat unit price, these parameters of measuring heat charge proportion, enter step 2:

Take according to area is warm=heating area * area heat unit price * area heat ratio, calculate area heat expense after, enter step 3:

The temperature and the flow of reception synchronous acquisition from temperature sensor, temperature measuring equipment and flowmeter carry out accumulation of heat and calculate and revise, and after carrying out the heat accumulation calculating, enter step 4:

According to metering hot expense=measure heat * measuring heat unit price * measuring heat charge proportion, after calculating metering heat and taking, enter step 5:

By the hot expense of the hot expense of the hot expense=area of formula+measure, area heat expense and metering heat that step 2 and step 4 are calculated are taken addition, calculate the actual expense that should hand over of user, and user's actual heat consumption and above-mentioned actual cost be input to the display buffer, and show hot expense, heat, area heat expense, measure hot expense by display.

As shown in Figure 3: if the user has bought IC-card, CPU will discern the IC-card that the user uses, and enter step 11, read the data in the card, and with this data storage in storer, and open valve, heat is entered the user; Following step 2,3,4,5 is identical with Fig. 2, after completing steps 5, should hand over the program of heat expense by formula delayed heat expense=forward purchased heat fee-actual, if the delayed heat expense equals 0, then by the heat supply of single-chip microcomputer instruction control valve breakdown, if the delayed heat expense is not equal to 0, then delayed heat expense, actual these parameters of heat expense of should handing over are input to the display buffer, are shown:
