Automatic adjusting method for output stable time of multifunctional output source

Abstract

The invention discloses an automatic adjusting method for output stable time of a multifunctional output source. The method comprises the following steps of: setting a control threshold value SA and primary sampling interval time t1 of the output source on a main station computer; selecting a typical point for each point of the output source as a measuring point, wherein sampling interval time t2 is equal to the primary sampling interval time t1; acquiring output source output data for one time for the typical point at every sampling interval time t2; after acquiring the data for 20 data points, calculating S value indicating an output source output fluctuation condition; and comparing the S value with the control threshold value SA, if the S value indicating the output source output fluctuation condition is not more than the control threshold value SA, determining that the output source output data acquiring interval time t is the sampling interval time t2, and if the S value indicating the output source output fluctuation condition is more than the control threshold value SA, automatically adjusting the sampling interval time t2 of the output source, and performing circulation.

Description

technical field [0001] The invention relates to the technical field of power system metering and detection, in particular to an automatic adjustment method for output stabilization time of a multifunctional output source. Background technique [0002] At present, the multi-functional output source is widely used in the detection of various devices or instruments in the power system, and provides high-precision output source signals for the devices or instruments under test. According to the requirements of the verification regulations, the reading value of the tested device or instrument refers to the display value after the output source outputs to the set value. Generally speaking, it takes a certain time for the output source to output to the specified value, which is commonly referred to as the stabilization time. . At present, the inspectors generally set the output stabilization time of an output source based on their senses and experience when performing manual inspe...

Problems solved by technology

At present, the inspectors generally set the output stabilization time of an output source based on their senses and experience when performing manual inspections. However, the output stabilization time of different manufacturers and models of multi-function output sources is different, and even when the inspection items are different, the output source The required stabilization time is also different

If the stabilization time of all schemes is set to the same value during automatic calibration, two situations may occur: When the actual output stabilization time required by the output source is less than the time manually set by the inspector, the calibration work will be increased. time, resulting in low work efficiency; when the actual output stabilization time required by the output source is greater than the time manually set by the inspector, the data will be collected when the output source has not risen to the predetermined value, reducing the reliability of the data
