Problems solved by technology

During the test process, the terminals of the DCS equipment are often loosened due to factors such as shaking during transportation or installation, which has a great impact on the accuracy of the test operation.
In addition, due to the manual point-by-point and repeated input, it is time-consuming and labor-intensive, and it is easy to cause fatigue and discomfort to the debugging personnel.
This verification method is difficult to analyze the error and evaluate the status of the DCS channel, resulting in low utilization of the verification results

Abstract

The invention discloses a DCS automatically checking method, which comprise a master checking unit, a slave checking unit and a wireless relay module. The method is characterized in that a standard data source can be driven in the in-situ or remote communication manner to conduct the whole-course automatic checking operation on a DCS. After that, the analysis and comparison treatment on the system data of the DCS with the data of the standard data source is conducted, so that the whole-course checking purpose of the DCS is realized. The method can be applied to the recovery test on the DCS at an industrial site and the batch checking of DCS cards.

Description

technical field [0001] The invention belongs to the technical field of DCS recovery testing on industrial sites, and relates to a DCS automatic calibration device. Background technique [0002] Because the DCS recovery test on the industrial site needs to verify a large number of data points, the traditional method requires the on-site debugger to control the signal source in the electronic room, and use the test pen to input the predetermined active or passive signal to the card channel of the DCS device. Each channel of the card inputs five-level signals, corresponding to 0%, 25%, 50%, 75%, and 100% of the range. The debugger at the engineer station needs to keep an eye on the DCS display screen, record the channel data and communicate with the site through the walkie-talkie. The personnel verify the input signals of different gears. When there is a large error between the data on the DCS display screen and the data input to the card by the on-site personnel, the correspon...
