A kind of many voltage monitoring instrument test systems tested based on automated closed-loop, including test main frame, voltage monitoring instrument Test device and voltage monitoring instrument, the test main frame output end pass through connection and the input of voltage monitoring instrument test device Connection, the voltage monitoring instrument test device output end is connected by connection with voltage monitoring instrument input, the voltage prison Instrument output end is surveyed to be connected with test main frame input by connection, the test main frame control voltage monitor test device Output, the voltage monitoring instrument test device output voltage test signal is tested voltage monitoring instrument and passed to tested voltage monitoring instrument It is defeated to arrive test main frame, so that test voltage monitor.
On the basis of above-mentioned technical proposal, the test main frame selects computer computer.
On the basis of above-mentioned technical proposal, the voltage monitoring instrument test device selects PDT-600 models, the voltage prison Survey in instrument test device and set data processing unit and voltage amplifier, and data processing unit is connected with voltage amplifier, it is described Arm processor and on-site programmable gate array FPGA are set in data processing unit.
On the basis of above-mentioned technical proposal, the voltage monitoring instrument selects XJDT-1 models.
The utility model overcomes problems with:
1st, test system can be required according to test event, flexibly work out test template.
2nd, test system can read tested voltage monitoring instrument data automatically.
3rd, the tested voltage monitoring instrument data and standard value of reading can be compared in test system, and automatic calculate is missed Difference, carries out result and comments
4th, test system can read the data of many voltage monitoring instruments simultaneously, generate multiple test report.
The utility model solves to test existing workload greatly to voltage monitoring instrument in the past, the problem of time-consuming.
Brief description of the drawings
