Embodiment 1

[0053] Such as figure 1 Shown, the present invention a kind of rectifying system start-up control method based on DCS system, comprises steps:

[0054] S1. Inform the electrical operator to turn on the high voltage switch through the output signal of the DCS system;

[0055] S2. Open the interlock of the rectification system through the DCS system, and reset the stop signal;

[0056] S3. Detect whether the rectification system meets the start-up standard through the PLC controller of the rectification system;

[0057] S4. When the rectification system meets the start-up standard, send a start-up signal to the rectification system through the DCS system, and then receive the rectification system operation signal sent by the rectification system;

[0058] S5. Adjust the parameters of the rectification system through the PLC controller to make the rectification system run normally.

[0059] Further, such as figure 2 As shown, step S3 specifically includes:

[0060] S31. Sen...

Embodiment 2

[0078] Such as Figure 5 Shown, the present invention a kind of rectifying system start-up control system based on DCS system, comprises:

[0079] The output notification module is used to notify the electrical operator to turn on the high voltage switch through the output signal of the DCS system;

[0080] The interlock release module is used to open the interlock of the rectification system through the DCS system and reset the stop signal;

[0081] The start-up standard detection module is used to detect whether the rectification system meets the start-up standard through the PLC controller of the rectification system;

[0082] The operation module is used to send a start-up signal to the rectification system through the DCS system when the rectification system meets the start-up standard, and then receive the rectification system operation signal sent by the rectification system;

[0083] The adjustment module is used to adjust the parameters of the rectification system t...

Abstract

The invention belongs to the technical field of rectification system control, and provides a rectification system starting control method based on a DCS (Distributed Control System), which comprises the following steps: S1, outputting a signal through the DCS to inform an electrical operator to turn on a high-voltage switch; s2, opening interlocking of the rectification system through a DCS system, and resetting a parking signal; s3, detecting whether the rectification system meets the driving standard or not through a PLC of the rectification system; s4, when the rectification system meets the driving standard, sending a driving signal to the rectification system through the DCS system, and then receiving a rectification system operation signal sent by the rectification system; and S5, adjusting parameters of the rectification system through the PLC to enable the rectification system to operate normally. The rectification system starting control system based on the DCS have the advantages that one-key starting of the rectification system is achieved, operation and working condition judgment can be automatically carried out on a field water pump, a direct current knife and the like, and the working efficiency of personnel is improved.

Description

technical field [0001] The invention relates to the technical field of rectification system control, in particular to a method and system for starting and controlling a rectification system based on a DCS system. Background technique [0002] The rectification system includes an electrolytic rectification system, which is mainly used in the production of chemicals. In the production process of chemical products, the electrolytic rectification system needs to control the electrolysis process through the magnitude of the current to ensure the quality of chemical production. [0003] At present, the rectification system is manually started and stopped, which needs to be manually operated on site, and the judgment conditions for starting and stopping are relatively complicated. Therefore, in the process of manual operation, there are often mistakes in judging the conditions for starting and stopping, which makes the production efficiency of the rectification system and the entir...
