Compared with the prior art, because of a plurality of meters share one communication module, the utility model improves the reliability, greatly reduces the cost and is convenient in installation.

Description

Multiepitope meter

[technical field]

The utility model relates to a kind of measuring instrument.

[background technology]

The mechanical type register is a kind of artificial direct-reading summary counter that is widely used on the measuring instruments such as ammeter, water meter, gas meter.The outstanding advantage of this class mechanical type register is, need not just can measure (as water meter, gas meter) by power supply, and shortcoming then is that manually reading is checked meter.

Along with the development of society, occur electronic technology at present the count value of this class mechanical type register is carried out long-range reading (being remote meter reading).This type of long-range reading device of general each mechanical type register configuration in the prior art.And this type of long-range reading device generally adopts the module of carrier wave, radio, communication mode such as wired to carry out communication, and still, the most cost of these modules is higher, is difficult to large-scale popularization.

[utility model content]

Cause in order to overcome long-range reading device of each meter configuration in the prior art long-distance meter-reading system with high costs, install keep difficulty technical matters, the utility model provides that a kind of cost is low, degree of stability is high and installs and keep multiepitope meter easily.

The technical scheme that above-mentioned first technical matters that solves the utility model is adopted is: a kind of multiepitope meter is provided, comprises that at least two gauging tables, each gauging table comprise metering module, these at least two gauging table common user communication modules.

With respect to prior art, the beneficial effect of the utility model multiepitope meter is: because the utility model in the shared communication module of a plurality of gauging tables, has not only improved reliability but also can reduce cost significantly, install more easy.

[embodiment]

Below in conjunction with drawings and embodiments the utility model is further specified.

Referring to Fig. 1, the principle of the utility model multiepitope meter is: with needed control module of remote meter reading and communication module is that a plurality of independent gauging tables are shared, such as 100 ammeters are arranged in the building, the distant kilowatt meter recorder that these 100 ammeters are all needed is reduced to shared one so.This distant kilowatt meter recorder carries out read operation to each ammeter, shows reading the display device that the result delivers to each ammeter respectively, will read the center of checking meter that the result sends by shared communication module simultaneously; Conversely, various operations also can be carried out to each ammeter by this shared distant kilowatt meter recorder in the center of checking meter.

The utility model multiepitope meter can be applied in each gauging table that needs remote meter reading, such as water meter and electric energy meter.Below be example with electric energy meter and water meter respectively just, describe the utility model in detail:

Consult Fig. 1 and Fig. 2, the utility model multiepitope meter is applied in the electric energy meter, and described multiepitope meter 10 comprises 4 independent electric energy meters, and each gauging table all comprises an independent metering module 20, display device 30.Multiepitope meter 10 only uses a control module 40 and a communication module 50.

Described control module 40 is single chip computer AT MEGA8, and described display device 30 is LCD, and electric energy metrical module 20 connects the SPI interface of single-chip microcomputer by the SPI serial ports.Described single-chip microcomputer carries out read-write operation to each metering module 20, finishes verification, adds up, testing, and the electric energy accumulated value of each metering module 20 is sent to corresponding LCD chip for driving HT1621 to show electric energy numerical value on LCD separately.Communication module 50 sends to the center of checking meter with data again.Described communication module 50 is radio receiving transmitting module or power carrier module, and it is connected with control module 40 by the SPI serial ports, finishes remote meter reading, remote detection control function and sends to communication module 50.

Consult Fig. 3 and Fig. 4, the utility model multiepitope meter is applied in the water meter, and described multiepitope meter comprises 4 independent water meters, and each water meter all comprises an independent metering module (figure does not show), display device 70.Multiepitope meter only uses a control module 90 and a communication module 100 to carry out remote meter reading.

Described control module 90 is single chip computer AT MEGA8L, and each water meter measurement module is passed through I ²The C serial ports connects the I of single-chip microcomputer ²C interface, described single-chip microcomputer carries out read-write operation to each metering module, finishes verification, adds up, testing, and the water yield accumulated value of each metering module is sent to corresponding display device 70, and send to communication module 100.Described communication module 100 is radio receiving transmitting module or power carrier module, and it is connected with control module 90 by the SPI serial ports, finishes remote meter reading, remote detection control function.

In the present embodiment, multiepitope meter comprises a generator, be installed in before each gauging table on the water (flow) direction, when having water to flow, current drive generator work, the electric energy that generator produces charges to farad capacitor behind the bridge rectifier filtering voltage regulation, and for single-chip microcomputer and communication module 100 work.Farad capacitor is made reserve battery and is used, and when not having current to generate electricity, farad capacitor can be powered a period of time.Like this, even without external power supply, this multiepitope meter also can be checked meter normally.

Fig. 5 also shows the multiepitope meter of another structure, and its change is to change input end into 8.

The utility model is a shared communication module and control module in a plurality of gauging tables, the mode of joining a distant kilowatt meter recorder with respect to gauging table in the prior art, the utility model has not only improved reliability but also can reduce cost significantly, and installation and maintenance is more easy.
