Description
Technical field
The present invention relates to the communication simulation type metering electric energy meter of teaching, training.
Background technology
Operations staff for power system, especially check meter and the personnel of electric-power metering relevant station, when pre-job giveing training, need to see various data intuitively, including active energy, reactive energy, four-quadrant electric energy, and multi-functional peak valley flat table meter, the kind of gauge table and wiring can there be basic insight and operation simultaneously, use real electric energy meter cannot collect various data really, when needing various data, must run long period or change CT, PT, difficulty is big, the longest.In large artificial system, function of measuring is the most particularly important, but the truthful data of analogue system does not often reach simulation requirements.In order to solve an above-mentioned difficult problem, develop the communication simulation type metering electric energy meter of a kind of simulated teaching training, every data function of multifunctional electric energy meter can be convenient to use, the function such as wiring, communication can be put into practice again, simultaneously in large artificial teaching and training system, can use as emulation gauge table.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is an object of the invention to provide communication simulation type metering electric energy meter, by the way of fieldbus, metering electric energy meter is arranged measurement data and various electric quantity data, so greatly reduce the cost of emulation experiment, the convenient function of measuring built in large artificial training system.
The purpose of the present invention realizes by the following technical solutions:
Communication simulation type metering electric energy meter provides the various functions of multifunctional meter metering electric energy meter, such as DL/T645-1997 communication protocol data-interface, current sample, voltage sample terminal, the liquid crystal display etc. of Multifunctional measuring table, and powered to gauge table by voltage sample interface, maintain the various functions of general multifunctional electric energy meter.
Further, additionally increasing RS485 communication interface, metering electric energy meter arranges measurement data and various electric quantity data, set data class follows the various data of defined in DL/T645-1997 stipulations.When gauge table is write data by analogue system, do not affect other system digital independent to electric energy meter.
Further, in order to improve the efficiency of data write, the mode of self-defined stipulations is used to write data.Amount to and use six data message write data, distinguished by control code.Data form is: Start(1Byte)+address (1Byte)+control code (1Byte)+data length (1Byte)+data (nByte)+verification (1Byte)+end mark (1Byte).Control code and the corresponding relation reading data are shown in Table 1.
