Background technology
At present, heating installation metering, the method for chargeing generally have two kinds of forms: the one, generally adopt in developed country, draw the data of user's actual consumption heat through computing and be presented on the calorimeter according to the flow of hot water in the unit interval and inflow temperature and return water temperature difference, relevant departments charge in view of the above; The 2nd, generally adopt the method charge of the payment at a lump rate of sharing by area in China.What of user's actual use heat or cold are the charge method that China adopts can not reflect effectively, lack fair, rationality, and energy dissipation is serious, the charge difficulty, can not take compulsory measure to the user that do not pay dues, heating enterprise and government are caused very big burden, even can produce serious social concern and for, contradiction between needing.
The utility model content
The purpose of this utility model is at the problems referred to above, and a kind of card type prepayment heat energy table is provided, and calculates and charge to be used for the heat energy of user's actual consumption.
The technical solution of the utility model is: a kind of card type prepayment heat energy table, comprise into water temperature probe, backwater temperature probe, little process chip, flow sensor, display, storer, deck, wherein intake temperature probe, backwater temperature probe places respectively on the water inlet pipe and on the return pipe, the other end is connected with little process chip, and flow sensor, display, storer, deck also are connected respectively at little process chip.
Above-mentioned card type prepayment heat energy table, it is further characterized in that described flow sensor is the non-magnetic flow quantity sensor, and described display is a LCD display, and described storer is permanent storage EEPROM.
Above-mentioned card type prepayment heat energy table, be characterised in that further it also comprises motorized valve, described motorized valve is made up of valve control plate, motor, microswitch, reduction gearing and ball valve, and wherein valve control plate is to be made of alarm lamp, MCU chip, communication interface, motor driver and positional information device.Motorized valve is installed on the medium pipeline, by the order that the communication interface reception connection of valve control plate is sent, explains through the MCU chip, lights alarm lamp, or forward and reverse rotation of control motor, thereby handles the open and close of valve.
Card type prepayment heat energy table of the present utility model uses the non-magnetic flow quantity sensor, and stain resistance is strong; Adopt up-to-date little process chip, LCD display, low in energy consumption, performance good; Supporting use motorized valve has guaranteed user's timely charge with the break-make of control medium pipeline and has prevented the waste of energy.
Description of drawings
Fig. 1 is the schematic block diagram of the utility model card type prepayment heat energy table;
Fig. 2 is the installation diagram of the utility model card type prepayment heat energy table;
Fig. 3 is the composition frame chart of motorized valve of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail as follows:
A kind of card type prepayment heat energy table, as shown in Figure 1, the PT1000 temperature probe, non-magnetic flow quantity sensor, permanent storage EEPROM, the IC-card seat that comprise little process chip, LCD display, pairing, wherein intake temperature probe, backwater temperature probe places respectively on the water inlet pipe and on the return pipe, the other end is connected with little process chip, and non-magnetic flow quantity sensor, LCD display, permanent storage EEPROM, IC-card seat also are connected respectively at little process chip.This instrument applicable situation is: central heating and be the domestic heating of heat-conducting medium with water and adopt cooling system, and metering is adopted heat and is adopted cold, and hot and cold metering is changed automatically, need not add intervention.
The heat energy table uses the non-magnetic flow quantity sensor, and stain resistance is strong; Adopt that up-to-date MCU chip, LCD show, the PT1000 temperature probe of pairing, low in energy consumption, performance good; Designed embedded program, can open circuit to temperature probe, battery electric quantity deficiency, flow sensor fault etc. carry out record, and register error date of taking place; The IC-card seat has strengthened anti-attack ability with corresponding observation circuit.The heat energy table is equipped with permanent storage EEPROM, can be at retention data after the power failure more than 10 years.Design has the IC-card of multiple function: " subscriber card " is used to purchase in advance heat, and " maintenance code ", " card changes the outfit ", " the family card disappears " etc. are convenient to the management of competent authorities to system, utilizes card to do the media of transmission information.
Heat energy table and motorized valve should be contained on the water inlet pipe, and gauge outfit is upwards just put; The backwater temperature probe is contained on the return pipe, and water inlet probe and backwater probe can not upside-down mountings.Described motorized valve is made up of valve control plate, motor, microswitch, reduction gearing and ball valve, and wherein valve control plate is to be made of alarm lamp, MCU chip, communication interface, motor driver and positional information device.Motorized valve and the supporting use of heat energy table also are the unique topworkies of card type prepayment heat energy table, are used for the break-make of water heating type central heating system, control branch family inlet channel, and its structured flowchart as shown in Figure 3.Valve control plate is accepted the order that the heat energy table is sent, and explains through MCU, lights alarm lamp, or just (instead) of control motor to rotation, thus the open and close of manipulation valve.Four alarm lamps of present embodiment are in order to reflect heat energy table system state: battery alarm (redness), and expression motorized valve battery is under-voltage; Arrearage is reported to the police (yellow), and the heat that consumes as the user above the forward purchasing heat is this lamp flicker; Fault alarm (redness), during valve control board monitoring system discovery connection open failure, this lamp flicker; Stop up and report to the police (green), valve control board monitoring system discovery inlet channel stops up, this lamp flicker.Close valve: heat energy table voltage is low, motorized valve voltage is low all can cause the pass valve; The overdraw of user's consumption of calorie, valve control plate find that the connection disconnection also can cause the pass valve.
Most preferred embodiment of the present utility model is illustrated, and the various variations or the remodeling of being made by those of ordinary skills all belong to protection domain of the present utility model.
