Volt generated energy, it is known that the generating efficiency of photovoltaic panel；And can be by the relative analysis result of generated energy, for photovoltaic system
Operation maintenance personnel provide site inspection photovoltaic panel reference.In the photovoltaic generating system of 1MW, the quantity floor space of photovoltaic module
It is about 35 mu.For large-scale photovoltaic generating system, only the maintenance of photovoltaic panel is for operation maintenance personnel, just occupies major part
Time.
After traditional three-phase meter accesses in photovoltaic generating system, it is only capable of carrying out the measurement of voltage, electric current, electrical power etc., not
During school, function and the relative analysis of photovoltaic power generation quantity and timesharing add up.Operation maintenance personnel cannot learn the ruuning situation of photovoltaic panel rapidly,
Difficulty is added to the maintenance of photovoltaic panel.
Utility model content
For solving above-mentioned technical problem, this utility model provides a kind of three-phase meter, to reach to improve maintenance efficiency, reduces and safeguards
Cost, the purpose increased economic efficiency.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of three-phase meter, including power harvesting circuit, ARM core processor, push-button unit and display unit, described electric power is adopted
Collector, push-button unit and display unit are all connected with described ARM core processor, it is characterised in that described three-phase meter also wraps
Include clock chip, 485 communication units, On-off signal unit and the output switch parameter list being connected with described ARM core processor
Unit.
In such scheme, described power harvesting circuit gathers core by three-phase power and is connected with described ARM core processor.
By technique scheme, the three-phase meter that this utility model provides compared with prior art, has the advantage that
1, this three-phase meter can preserve generated energy, and has history data store function, and user can be looked into by 485 bus access
See that historical data, historical data include the generated energy on the photovoltaic array same day by this device, of that month generated energy, sending out then
Electricity and gross generation；
2, operation maintenance personnel can be to whether checking that photovoltaic panel provides reference in the middle of the generated energy relative analysis of every day；
3, by this month or generated energy data then, operation maintenance personnel can check the generating efficiency of photovoltaic matrix.

Three-phase meter as shown in Figure 1, including power harvesting circuit, ARM core processor, push-button unit and display unit, electricity
Power Acquisition Circuit, push-button unit and display unit are all connected with ARM core processor, and three-phase meter also includes and ARM kernel processes
Clock chip, 485 communication units, On-off signal unit and the switch amount output unit that device connects；Power harvesting circuit passes through
Three-phase power gathers core and is connected with ARM core processor.
In the present embodiment, power harvesting circuit and three-phase power gather core to parameters such as the voltage of photovoltaic circuit, electric current, electrical power
It is acquired, and transmits to ARM core processor；ARM core processor carries out Treatment Analysis, and by analysis result by aobvious
Show that unit shows, it is simple to operator obtain information in time；Push-button unit is used for checking data and the setting that three-phase meter gathers
The parameter of three-phase meter；User can be transmitted a special modbus by 485 communication units and be instructed, and time command transmitted
To clock chip, thus when realizing the school of three-phase meter；The various data analyzed and processed can be uploaded to main by 485 communication units
CPU。
This three-phase meter owing to having time display function, can realize to different statistical time range every day, monthly, annual measurement data
Carry out photovoltaic theory generated energy analytical calculation, it is intended to draw the generated energy that different statistical time range is measured, can be that photovoltaic generating system sets
Meter personnel and decision-maker provide reference.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model.Right
The multiple amendment of these embodiments will be apparent from for those skilled in the art, as defined herein typically
Principle can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.Therefore, this practicality
The novel the embodiments shown herein that is not intended to be limited to, and be to fit to and principles disclosed herein and features of novelty phase
The widest consistent scope.
