Description
Technical field
The utility model is related to electric energy meter technical fields, and in particular to arrive a kind of three-phase electric energy meter.
Background technology
With the deep construction of intelligent grid and the fast development of smart city, intelligent electric energy meter not only needs can be to electric energy
It is measured, with concentrator or data collector into row data communication, should be able to also extend the data acquisition to " water, air and heat " table
And two-way interaction is realized by indoor interactive terminal and user.Intelligent electric energy meter in existing design is only capable of supporting and concentrate
Device or data collector realize that data communicate by single channel, cannot be satisfied the demand with expansion equipment data interaction, and mould
Block storehouse space is smaller, and mating communication module is size-constrained.Without programming key design, it can not ensure parameter safety by hardware, this
Safeguard that end uses far infrared, traffic rate and stability limited in ground.
Therefore need a kind of new technical solution to solve the above problems.
Invention content
The purpose of this utility model is in view of the deficiencies of the prior art and provides a kind of new three-phase electric energy meter, can solve
Communication stability and the bad problem of traffic rate, and it is convenient for expanding communication equipment.
To achieve the goals above, the utility model adopts the following technical solution：
A kind of three-phase electric energy meter, including pedestal, the upper cover being covered on pedestal, tail-hood, communication module storehouse, mainboard, power supply
Unit；The lower end of the pedestal and upper cover is contained in tail-hood；The upper lid is equipped with programming button, infrared communication mouth；It is described
Liquid crystal display is located at upper cover upper interior；The communication module storehouse is installed on upper cover front lower section；Said supply unit and electric energy meter
Mainboard is integrated in one on veneer circuit board, and the veneer circuit board is equipped with module communication interface；The module communication interface
Including two-way UART communication interfaces.
Compared with prior art, the utility model has the advantage of：The three-phase electric energy meter of the utility model uses near-infrared
The communication stability and traffic rate of local maintenance is effectively ensured；Using the compatible a variety of communication modules in independent module storehouse；Mould
Block communication interface is designed using dual uart, can be supported through independent channel and communication mode and expansion equipment such as " water, air and heat " table
And indoor interactive terminal is communicated；Power supply unit carries out integrated design with mainboard, and can save connector and pcb board makes
With effectively save cost.
Further, the programming button is protected with lead sealing.After programming key is pressed in destruction lead sealing, just allow using in plain text
It modifies to ammeter parameter.Because of the protection of lead sealing and parameters hardware protection, any unauthorized personnel changes parameter all will be by
It was found that.So as to which parameter safety is effectively ensured.
Further, the infrared communication mouth uses near infrared communication.
Further, the programming button is located above upper cover face side；The infrared communication mouth is located under programming button
Side.
Further, mainboard, power supply unit are located in the cavity formed after pedestal and upper cover assembling.
Description of the drawings
Fig. 1 is the stereogram exploded view of the utility model three-phase electric energy meter.
Specific implementation mode
The utility model is further described below with reference to the drawings and specific embodiments in specification, but not
Therefore the scope of protection of the utility model is limited.
As shown in Figure 1, the three-phase electric energy meter in the present embodiment, including pedestal 1, upper cover 2, tail-hood 3, liquid crystal display 4, programming are pressed
Key 5, infrared communication mouth 6, communication module storehouse 7, module communication interface 8, mainboard 9, power supply unit 10；
Specifically connection relation is：The pedestal 1 and the lower end of upper cover 2 are contained in tail-hood；The upper lid, which is equipped with, to be compiled
Journey button 5, infrared communication mouth 6；The communication module storehouse 7 is installed on 2 front lower section of upper cover；Said supply unit 10 and electric energy meter
Mainboard 9 is integrated in one on veneer circuit board, and the veneer circuit board is equipped with module communication interface 8.The module communication connects
Mouth (8) uses 16 core function pin definitions modes, including two-way UART communication interfaces.
In the present embodiment, programming button 5 is increased in electric energy meter, and is programmed button and protected with lead sealing.Destroy lead sealing
After pressing programming key, just allow to modify to ammeter parameter using plaintext.Because the protection of lead sealing and parameters hardware protection, appoint
What unauthorized personnel changes parameter and will be found.
In the present embodiment, further include that infrared communication mouth 6 uses near infrared communication, compare far infrared, it can by near-infrared
The reliability and traffic rate of communication is effectively ensured, maintenance personnel can carry out electric energy meter reliable and stable dimension by near-infrared mouth
Shield.
In the present embodiment, further include that communication module storehouse 7 is independently arranged, it is compatible so as to be designed using large scale
With the development of technology, the module of other communication schemes of appearance, not because dimensional space size limits the design of module.
In the present embodiment, further include that module communication interface 8 supports two-way UART, acquired with data not influencing electric energy meter
On the basis of device communication channel such as carrier communication, it can support using other communication modes such as communication and " water, air and heat "
Other expansion equipments such as table and indoor interactive terminal are communicated.
In the present embodiment, further include power supply unit 10 and mainboard 9 uses integrated design, can effectively save connector and
Pcb board uses, cost-effective.
