Abstract
The utility model relates to a microcomputer intelligent calorimeter which is composed of a casing, an IC card seat arranged on the casing, and a control circuit board arranged in the casing. The control circuit board is composed of an SCM, a data acquisition circuit, an A/D converting circuit, a card reader, a memory, a buzzer and a liquid crystal display, wherein, input terminals of both ends of the data acquisition circuit are respectively connected with a temperature sensor and a magnetic pulse flowmeter installed at a water admitting pipe of a radiator and a temperature sensor installed at a water escaping pipe of the radiator. The utility model has the advantages of high metering accuracy and energy saving, and the utility model can solve the problem that the heating fee is difficult to charge at present.
Description
The utility model relates to a kind of meter, the hot meter of particularly a kind of microcomputer-recognized intelligent type.
At present China has produced some new problems in the development central heating: 1, difficult charge, and management is difficult, and user's phenomenon of being in arrears with or refusing to pay heating cost makes the burden of heat supply department more and more heavier now, and the loss situation is difficult to improve.2, heating power imbalance.At present in the world the employing installed the thermodynamic equilibrium that thermodynamic equilibrium valve and differential pressure control valve guarantee system additional more in system, and at each user's reload temperature operation valve, temperature can need to set with the user, user's heat what metering by mechanical flow meter and thermometer respectively the reading manual metering calculate heat.Such metering method quite bothers.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of microcomputer-recognized intelligent type hot meter, its measuring accuracy height, and energy savings can solve the problem that current heating installation takes difficult charge.
As above design, the technical solution of the utility model is:
The hot meter of a kind of microcomputer-recognized intelligent type is characterized in that, is made up of IC-card seat on housing, the housing and the control circuit board that is fixed in the housing; Control circuit board is by single-chip microcomputer, data acquisition circuit, and A/D change-over circuit, card reader, memory, hummer and LCD are formed; Wherein, two input ends of data acquisition circuit respectively with the temperature sensor that is installed in radiator inleting pipe, the magnetic-pulse flowmeter is connected with the temperature sensor that is installed in radiator outlet pipe; One pin of the output terminal of data acquisition circuit and single-chip microcomputer joins, and another pin of single-chip microcomputer and the input end of A/D change-over circuit join, and the output terminal and the LCD of A/D change-over circuit are joined; Card reader, memory, hummer and the temperature control valve that is installed in radiator inleting pipe join with the pin of single-chip microcomputer respectively.
The utility model has the advantages that: 1, solved the cumbersome of artificial meter reading calculating, improved measuring accuracy; 2, accomplish to purchase card with heat, eradicated the un-reasonable phenomenon of the heating of not paying dues, solved the problem of long-term difficult charge; 3, improved heating effect, energy savings.
Below in conjunction with drawings and Examples the utility model is further described
Fig. 1 is a schematic appearance of the present utility model.
Fig. 2 is a schematic diagram of the present utility model.
As shown in the figure: the hot meter of a kind of microcomputer-recognized intelligent type, form by IC-card seat 2 on housing 1, the housing and the control circuit board that is fixed in the housing; Control circuit board is by CPU, data acquisition circuit, and A/D change-over circuit, card reader, memory, hummer and LCD are formed; Wherein, two input ends 9,10 of data acquisition circuit respectively with the temperature sensor 5 of the water inlet pipe 4 that is installed in heating radiator 3, magnetic-pulse flowmeter 6 is connected with the temperature sensor 8 that is installed in radiator outlet pipe 7; The output terminal 11 of data acquisition circuit joins with the pin one 2 of CPU, and the pin one 3 of CPU joins with the input end 18 of A/D change-over circuit, and the output terminal 19 and the LCD of A/D change-over circuit are joined; Card reader, memory, hummer and the temperature control valve 20 that is installed in radiator inleting pipe join with the pin one 7,14,16,15 of CPU respectively.
Principle of work of the present utility model:
Will be by the temperature sensor that is installed in the heating radiator water inlet pipe and water outlet pipe, record the water temperature of turnover heating radiator respectively and record used hot water flow by the magnetic-pulse flowmeter that is installed in radiator inleting pipe, all being transferred to data acquisition circuit carries out being transferred to CPU according to cpu instruction after the signal processing and amplifying, CPU is according to after heat=△ t * flow calculates, its simulating signal is transported to the A/D change-over circuit, after the A/D change-over circuit is converted to digital signal, is transferred to LCD and demonstrates used heat again by it.The heat that card reader promptly will consume the information in the IC-card (purchasing the card heat) is input to the CPU in this meter, As time goes on, it is (when used heat runs low in the card) when being depleted to critical heat, the automatic alarm of hummer in this meter is imported once more will consumption of calorie (purchasing the card heat), and this meter will be remembered and the remaining sum of last time is added up.The memory storage of this meter is finished by memory.This meter stops action being finished by temperature control valve.The temperature control valve user can set up room temperature as required on their own, and it promptly plays room temperature control action (this valve is regulated flow automatically when reaching design temperature) and can accept the cpu instruction valve-off again and stop heat supply.
