Description
Technical field
This utility model belongs to electric energy instrument technical field, is specifically related to a kind of tester for electric energy meter.
Background technology
Electric energy meter is because of the hardware parameter difference of current-voltage sampling device and the characterisitic parameter of analog to digital conversion circuit
Difference so that the error in dipping of every electric energy meter is required to be calibrated in the range of required precision.Due to
Toward the restriction of electric energy meter design, all use and change the electric ginseng using loop in electric energy meter hardware circuit
Number adjusts electric energy meter sampling and measuring accuracy.This mode can only use the mode of manual work, belongs to
Nonlinear Adjustment is imitated, and rate is low, and measuring accuracy concordance is poor, and workload is big, utilization rate of equipment and installations is low,
Not only become production capacity bottleneck, and seriously limit measuring accuracy realization substance raising.
Utility model content
The purpose of this utility model is defect and the deficiency existed for prior art, it is provided that a kind of linear
, the tester for electric energy meter of automatization.
For achieving the above object, this utility model is by the following technical solutions: including: PC, standard source,
Standard scale and power module, described PC is connected with standard source, standard scale respectively, is used for controlling mark
Quasi-source and the duty of standard scale；Described PC passes through serial server and some electric energy meter phases to be measured
Connect row data communication of going forward side by side；Described power module is connected with standard source and standard scale respectively and provides electricity
Energy；Described standard source and standard scale have been also respectively connected with warning system.
Further, described serial server is connected with PC serial ports, and described serial server connects
48 epi-position correction platforms, electric energy meter to be measured and 48 epi-position correction platforms are had to be connected.
Further, described warning system includes audible alarm unit and alarm lamp.
Compared with prior art, this utility model has following useful technique effect: this device passes through PC
Machine controls standard source, makes standard source, by program control requirement, electric energy meter be loaded normal voltage and normalized current, and
Read the electric energy meter error data that standard scale extracts the error compensation parameter generating correspondence.Taken by serial ports
Business device directly reads electric energy meter voltage measurement data and current measurement data, and by serial server and intelligence
Energy electric energy meter communication, by error compensation parameter read-in electric energy meter.This device achieves electric energy meter error in dipping
Regulation fairly linear with voltage and current measurement error, and achieve automatization's calibration.
Accompanying drawing explanation
Fig. 1 is this utility model system architecture diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Seeing Fig. 1, this utility model includes: PC, standard source, standard scale and power module, described
PC is connected with standard source, standard scale respectively, for controlling the duty of standard source and standard scale；
Described PC is connected with some electric energy meters to be measured row data communication of going forward side by side by serial server；Described
Serial server is connected with PC serial ports, and described serial server connects 48 epi-position correction platforms, treats
Survey electric energy meter and 48 epi-position correction platforms are connected.Described power module is connected with standard source and standard scale respectively
Connect and electric energy is provided；Described standard source and standard scale have been also respectively connected with warning system.Described warning system
Including audible alarm unit and alarm lamp.
The PC of this device, its function specifically includes that 1) control standard source, make standard source want by program control
Ask and electric energy meter is loaded normal voltage and normalized current.2) the electric energy meter error data that standard scale extracts are read
And generate the error compensation parameter of correspondence.3) electric energy meter voltage measurement number is directly read by serial server
According to and current measurement data.4) by serial server and intelligent electric energy meter communication, by error compensation parameter
Write electric energy meter.One serial server, is connected with PC serial ports, virtual expands out 48 serial ports,
Realize PC and 48 electric energy meter time-sharing communications, read and write electric energy meter calibrating parameter.Standard source, at PC
Under the control of machine, it is provided that the normal voltage used by electric energy meter and normalized current.Standard scale: by reading electricity
The error equivalent frequency signal that energy table pulse output terminal sends, to measure electric energy meter standard metering error,
Read for PC.Warning system, it is provided that standard source and standard scale malfunction classified prompt, passes through sound
Sound and different indicator lamp system provide corresponding malfunction.
During work, electric energy meter to be corrected is hung up 48 epi-position ammeter platforms, and opens electric energy meter programming state；
Then running PC and carry out the program control control of calibration, detection electric energy meter is in the strong, weak electricity UNICOM feelings of correction platform
Condition, detect by after automatically into calibration programmed state.Complete the setting of Random Communication address, standard error
Read, error compensation data generates, error compensation data writes, standard error data re-read, sentence
Break qualified and exit program control.Finally, calibration enters after completing and rechecks step, all rechecks qualified health check-up matter
Amount portion examines entirely.
This device makes electric energy meter error in dipping and voltage and current measurement error realize fairly linear regulation, and
Automatization's calibration is made to be possibly realized.
