Voltage source remote calibration system and calibration method

Abstract

The invention provides a voltage source remote calibration system and calibration method. The voltage source remote calibration system comprises a field control computer and a remote control computer. The field control computer is connected with a to-be-detected meter and a first time interval counter; the to-be-detected meter is a direct-current voltage source; and the to-be-detected meter is connected with the first time interval counter through a first voltage frequency conversion module, and the first time interval counter is also connected with a first GPS common-view receiver. The remote control computer is connected with an etalon and a second time interval counter; the etalon is connected with the second time interval counter through a second voltage frequency conversion module, and the second time interval counter is also connected with a second GPS common-view receiver; and data transmission is carried out between the field control computer and the remote control computer through a DataSocket communication technology. Compared with a traditional calibration mode, the remote calibration system has the advantages that the calibration time is greatly shortened, the labor cost is reduced, and the calibration efficiency is improved.

Description

technical field [0001] The invention relates to the field of electrical measurement calibration, in particular to a voltage source remote calibration system and a calibration method. Background technique [0002] Measurement is an activity to realize the unity of units and ensure the accuracy and reliability of measurement values, which is related to the national economy and people's livelihood. The value transfer and traceability of measuring instruments are realized through metrological verification and calibration. From a technical point of view, verification and calibration are comparative methods. It is necessary to compare the measurement standard with the tested device under the specified measurement environment. Most of them need to be carried out offline. When verifying or calibrating, the working measuring instruments are removed and sent to the corresponding technical institution for static or steady-state testing in a specified experimental environment. The disa...
