Problems solved by technology

The start-stop process of each device is very complicated, so its process control is also very challenging. Almost all process variable values ​​​​will change rapidly during the production process, and it is necessary to ensure that nothing goes wrong to achieve the correct steady state
Due to the variability of the operating environment, it is easy to cause very serious nonlinear problems. From the perspective of economy and safety, it is necessary to ensure the stability of the process of starting and stopping

Embodiment 1

[0031] Such as figure 1 and figure 2 As shown, a method for one-key startup and shutdown of a chemical plant includes a controller, a controlled party, and an OPC interface. Valves in the device, etc., the data scheduling between the start-stop navigation system and the DCS control system realizes data transmission through the OPC interface, and its control steps are as follows:

[0032] (1) Install the start-stop navigation system on a notebook or desktop, and configure OPCClient and OPCServer. The OPCServer collects data for the OPCClient to connect with a standard interface, and connects the start-stop navigation system with the DCS control system through a network cable to ensure that the notebook or desktop The computer and the DCS control system are in the same local area network;

[0033] (2) OPCServer collects real-time data from the DCS control system, and transmits the data to OPCClient, and OPCClient transmits the data to the custom byte position of the control s...

Abstract

The invention discloses a method for one-key turning on / off of chemical engineering equipment. A controlling side, a controlled side, and an OPC interface are arranged. The controlling side is a turning-on / off navigation system; the controlled side is a DCS control system; and data scheduling and data transmission between the turning-on / off navigation system and the DCS control system is realized by the OPC interface. With the method, accuracy and timeliness of dealing with problems by the operator can be improved; security problems of the misoperation caused by frequent manual operations during the turning on / off process of the chemical engineering equipment and the like can be solved; and thus the operation and production risks can be substantially reduced. The intelligent and automatic control of the turning on / off process of the chemical engineering equipment can be realized.

Description

technical field [0001] The invention relates to the technical field of process control for starting and stopping a chemical device, in particular to a one-key starting and stopping method for a chemical device. Background technique [0002] With the rapid development of petrochemical advanced production technology and the continuous improvement of mechanization and automation, the technical requirements for driving and parking are getting higher and higher. The start-stop process of each device is very complicated, so its process control is also very challenging. Almost all process variable values ​​will change rapidly during the production process, and it is necessary to ensure that nothing goes wrong to achieve the correct steady state. Due to the variability of the operating environment, it is easy to cause very serious nonlinear problems. From the perspective of economy and safety, it is necessary to ensure the stability of the process of starting and stopping. Aiming a...
