A voltage source remote calibration system and calibration method

Abstract

The invention provides a voltage source remote calibration system and a calibration method. The voltage source remote calibration system includes an on-site control computer and a remote control computer; the on-site control computer is connected to the meter to be inspected and the first time interval counter; the meter to be inspected is a DC voltage source; the meter to be inspected is connected to the The first time interval counter is connected, and the first time interval counter is also connected to the first GPS common-view receiver; the remote control computer is connected with the standard device and the second time interval counter; the standard device is connected with the second voltage frequency conversion module The second time interval counter is connected, and the second time interval counter is also connected to the second GPS common-view receiver; data transmission is performed between the on-site control computer and the remote control computer through DataSocket communication technology. Compared with traditional calibration methods, the remote calibration system of the present invention greatly shortens the calibration time, reduces labor costs, and improves calibration efficiency.

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...
