Detecting system quote, thus realize increase virtual electric energy meter function.
Described virtual list server is the socket server end of variable IP.
Communication is carried out by Transmission Control Protocol between described virtual list server and common interface module.
After described virtual list server runs, after serial ports passage of checking meter is opened, the Virtual table shelves of correspondence can be automatically generated
Case storage folder；Described archives storage file is corresponding with serial ports number, and the electric energy meter archives of its internal storage can be with it
In the file that its serial ports circuit is corresponding, the electric energy meter archives of storage are of the same name；One piece that described Virtual table archives are the most independent virtual
Electric energy meter, the filename of virtual electric energy meter archives is its address.
Described virtual list server operationally, understands the log record file of automatic creation system and each serial ports passage
The serial communication log log file of module；The log record file of described system have recorded institute when virtual list server runs
There are process data and the control instruction sending or receiving；Described serial communication log log file have recorded institute in serial communication
Some process datas and communication data.
This Virtual table for electric energy meter data acquisition terminal test system that the present invention provides, uses computer software
Technology, by calling packaged interface, with virtual list server communication, virtual list server is by specifying execution corresponding operating；
Serial ports passage on the PC that electric energy meter data acquisition terminal is opened with virtual list server is connected by physical circuit, it is achieved electricity
The automatic of electric energy meter data can be gathered table data collection station, therefore the versatility virtual electric energy meter of the present invention, receives other
The acquisition terminal test instruction that sent by common interface of system, carry out automatic or manual survey in electric energy meter data acquisition terminal
During examination, it is achieved electric energy meter controllable quantity, the test amendment of data, the amendment of communication baud rate and the setting of electric energy meter address, and
And test process data can record automatically.
Accompanying drawing explanation
Fig. 1 is the functional block diagram of the present invention.
