Several taximeter, is installed on central air-conditioning each extension set ventilation coil pipe and is connected with pipeline valve, and the switch of monitoring pipeline valve carries out disbursement and sattlement with the duty of point coiler, an accumulative point coiler effective time;

Several collector, is connected with multiple taximeter, receives the data that taximeter sends, and to taximeter relay forwarding control instruction;

Charging host machine, is connected with collector, receives the data of each taximeter that collector sends and carries out adjusting and storing, and sends instruction manage each taximeter.

Further, described taximeter and collector adopt Mbus bus to carry out data transmission.

Further, described collector and charging host machine adopt RS232 bus to carry out data transmission.

Further, described collector and charging host machine adopt 3G network to carry out data transmission, and the wireless communication frequency band of use is free frequency range.

Further: charging host machine can carry out timing, checks meter, the multiple instruction such as Long-distance Control, at times charging is arranged.

Beneficial effect

A kind of Central Air Conditioning Billing System of the present utility model carries out household metering according to the effective storage life of each user of central air-conditioning, charging according to quantity, decrease the dispute of estate management, the use habit of user is changed by accounting management, reduce the overall energy consumption of building, reduce operating cost by central charge, extend the air-conditioning life-span, advantages such as realizing user and thing doulbe-sides' victory also, have that cost is low, the convenient and operation maintenance of detail design is simple.

Accompanying drawing explanation

Fig. 1 is the systematic schematic diagram of Central Air Conditioning Billing System of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1, the schematic diagram of Fig. 1 Central Air Conditioning Billing System of the present utility model.

As shown in the figure, a kind of Central Air Conditioning Billing System of the present utility model comprises taximeter 10, collector 20 and charging host machine 30.Taximeter 10 adopts M-BUS communications protocol to carry out centralized automatic meter-reading management, be installed in central air-conditioning each point of coiler, accurate identification fan coil operational taps, according to high, medium and low three gears of fan coil, by the air-conditioning service time of each gear of metering central coil pipe of air-conditioner blower, be multiplied by the table cold (heat exchange power) of each gear of central air conditioning fan coil unit, the energy that each gear of central air conditioning fan coil unit consumes can be drawn.The energy consumed by each for central air conditioning fan coil unit gear is multiplied by energy unit price and show that every platform divides the electricity charge of coiler after being added.Its concrete computational process is as follows:

$W=\frac{T_d}{{\mathrm{\Σ}}_1^n{T}_d}\·(A+B)$

Wherein, W: the electricity charge that every Fans is dealt with; Td: every Fans volume of traffic monthly; N: the total quantity of fan coil; The total electricity charge of A; B: maintaining expense.

Collector 20 has Repeater and part management function, is connected with taximeters 10 all in region by M-BUS bus, receives the metering data that taximeter 10 sends.Data after gathering are sent to accounting server 30 by RS232 data/address bus after receiving the data that each taximeter 10 sends by collector 20.Collector 20 can supply water to metering region air-conditioning and carries out temperature detection and assign various instruction to according to measured value and set temperature value from trend taximeter 10.

Charging host machine 30 is higher management of whole system, the function having terminal management, data buffer storage, timing meter reading and monitor in real time.Charging host machine 30 1 aspect sends various instruction, and taximeter is passed under the relaying of collector 20, on the other hand, the various information collecting taximeter 20 carry out calculating and processing by charging host machine 30, also store the relevant parameters such as the various relevant measurement data of native system, collector 10 data, real time monitoring collector 10 duty and fault alarm are copied and accepted in timing simultaneously.Charging host machine 30 also can gather some other data, as the ammeter number of degrees or temperature conditions etc. simultaneously.

Charging host machine 30 runs what Win/NT platform, provides cost accounting module, can carry out the many kinds of parameters such as timing meter reading, Long-distance Control, at times charging and arrange, and arrange flexibly, perfect in shape and function, Information Organization is reasonable, easy to operate.Utilize management software to process by setup program automatically to calculate the central air-conditioning energy that each Fans coil pipe of user consumes, have the functions such as data statistics, bill output, inventory inquiry, arrearage forbidding, being applicable to any take fan coil as the central air conditioner system of end.There is the functions such as state acquisition, household metering, Centralizing inspection, arrearage forbidding, on-the-spot display.With entering as required, also can gather at times according to the difference of electricity price, adding up, and by functions such as period chargings

Above-mentioned wireless long-distance meter-reading system, integrated reading device 10 between building is also by network base station and concentrator 20 wireless connections, without the need to the winding displacement of complexity, construction is simple, maintenance cost is lower, due to the network of self-built numbers network base station, without the need to paying, operation cost is lower, and data upload is unrestricted.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
