Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of on-off control device with heat metering function, comprise: be installed on a point temperature controller for indoor, family 1, on-off valve 2, calorimeter 3 and be installed on the building calorimeter 5 of a building desired location, wherein temperature controller 1 is connected with on-off valve 2 communication by communication module 1.1, data-signal from a point on-off valve for indoor, family 2, calorimeter 3 gathers to MBus concentrator 4, a MBus concentrator 4 Ze Yu building calorimeter 5, upper machine communication connection respectively by MBus module 2.1,3.1.
Stealing circuit 2.2,3.2 is added respectively in described on-off valve 2, calorimeter 3.
When the utility model uses as calorimeter method metering device, the calorimeter 3 of point indoor, family is for measuring each user's heat use amount, and calorimeter 3 coordinates temperature controller 1 and on-off valve 2 controllable indoor temperature.Concrete methods of realizing: indoor ideal temperature is set by temperature controller 1, simultaneously temperature controller 1 Real-time Collection indoor actual temperature, after indoor actual temperature reaches design temperature, temperature controller 1 controls on-off valve 2 and closes, and stops heat supply; When indoor temperature is lower than design temperature threshold values, temperature controller 1 controls on-off valve 2 and opens, and starts heat supply, again closes until reach design temperature.The heat supplied in the measurable heat supplying process of calorimeter 3, is charged by heating load.
When the utility model uses as make-and-break time area-method metering device, indoor ideal temperature is set by temperature controller 1, simultaneously temperature controller 1 Real-time Collection indoor actual temperature, after indoor actual temperature reaches design temperature, temperature controller 1 controls on-off valve 2 and closes, and stops heat supply; When indoor temperature is lower than design temperature threshold values, temperature controller 1 controls on-off valve 2 and opens, and starts heat supply, again closes until reach design temperature.Record on-off valve 2 opening time in heat supplying process, in conjunction with each user heating area, by each user, heating cost is shared to the total amount of heat that a building calorimeter 5 measures.
The temperature controller 1 built-in intelligence reservation heating program of native system, user can set certain after time point, required indoor temperature, after setting, temperature controller 1, according to the temperature difference of indoor temperature and design temperature, is automatically selected valve opening time, is enable setting-up time point reach design temperature; After setting reservation heating information, when valve is not opened, and when indoor temperature changes, program recalculates Open valve time point automatically.
Temperature controller 1 realizes outside reservation heating function by built-in program, also can record the relation curve of indoor temperature ramp-up rate and valve opening time in actual use procedure, when generating the special reservation heating schedule being applicable to this user after the condition that record data reach certain, after user uses reservation heating function, can select to adopt built-in reservation heating program and special reservation heating program.
On-off valve 2 in the utility model and calorimeter 3 can adopt multiple power supply mode, as: external power supply is powered, and internal battery is powered.Also by the stealing of M-Bus data wire when there is in the circuit of on-off valve 2 and calorimeter 3 on-off valve stealing circuit 2.2 and calorimeter stealing circuit 2.3.When M-Bus data wire is connected, on-off valve 2 and the built-in stealing circuit of calorimeter 3, from the electricity needed for M-bus communication interface acquisition equipment, automatically switch to external power supply or powered battery when the electric energy that M-Bus data wire disconnects or stealing circuit obtains can not meet the user demand of electrical equipment.
On-off valve in the utility model and calorimeter can be Split type structures, also can be integral structures.In time adopting Split type structure, on-off valve and calorimeter have respective stealing circuit and M-Bus module respectively, and in time adopting integral structure, stealing circuit and the M-Bus module of on-off valve and calorimeter also can design all-in-one-piece circuit.
The utility model also possesses multiple warning function:
1, in make-and-break time area-method metering device, on-off valve 2 is the equipment that fault rate is the highest, and major failure is produce incrustation scale after Long-Time Service or the valve that causes because of quality problems fits badly and valve is not opened.In the utility model, after on-off valve 2 is closed, system can detect flow by calorimeter 3, and normal closedown flow is zero, and when on-off valve 2 is not closed tight, flow is non-vanishing, can be judged as on-off valve closing fault; After on-off valve 2 is opened, system can detect flow by calorimeter 3, and normal turn-on flow rate is non-vanishing, and when on-off valve 3 is not opened because of fault, flow is zero, can be judged as that on-off valve opens fault.Meanwhile, system can on host computer, M-bus concentrator 4 and calorimeter 3 display alarm information.
2, in this device, each calorimeter 3 flow sum should be identical with the flow of a building calorimeter 5, and when calorimeter 3 is contained in inlet pipeline, a building calorimeter 5 is contained in water return pipeline; Or calorimeter 3 is contained in water return pipeline, when a building calorimeter 5 is contained in inlet pipeline, water inlet end total flow should be identical with water side total flow.This device in real time can detect water inlet end total flow and water side total flow, can judge that pipe-line system exists leak source when systems axiol-ogy is obviously greater than water side total flow to water inlet end total flow, and on host computer and M-bus concentrator 4 display alarm information.
3, in this device, each calorimeter 3 heat sum should be similar to the calorie value of a building calorimeter 5 and ratio value is substantially fixing, this ratio value can be recorded as thermal losses parameter and be stored in system by system, when systems axiol-ogy has relatively large deviation to this thermal losses parameter and storing value, namely be judged to be calorimeter fault, and on host computer and M-bus concentrator 4 display alarm information.
