Automatic production method and system based on DCS (Distributed Control System) and handheld terminal

Abstract

The invention relates to an automatic production method and system based on a DCS system and a handheld terminal. The DCS system is in communication connection with the handheld terminal. The DCS system executes pre-edited production process control logic; the production process control logic comprises information which corresponds to a first program instance and is used for reminding a user to input information, and the first program instance is a program instance which needs the user to input the input information in the production process control logic; the method comprises the following steps that: when a DCS (Distributed Control System) executes a first program instance, the DCS pushes information which corresponds to the pre-configured first program instance and is used for reminding a user to input information to a handheld terminal; the handheld terminal receives input information input by a user and transmits the input information to the DCS; and the DCS continues processing according to the input information and the production process control logic to obtain a processing result.

Description

technical field [0001] The invention relates to the technical field of automated production, in particular to an automated production method and system based on a DCS system and a handheld terminal. Background technique [0002] In fine chemical, pharmaceutical, food and beverage industries, many of the production processes are not fully automated, but require manual interaction: such as manual feeding, manual measurement, manual confirmation, etc., and manual input of process data is required during the interaction process. The DCS system (Distributed Control System, Distributed Control System) determines the process to be executed next according to the process data entered manually. [0003] At present, the control system adopts the "client / server architecture". The control client is deployed in the central control room, and there is a certain distance between the central control room and the on-site production equipment. In the actual production process, when manual inte...

Problems solved by technology

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an automated production method and system based on a DCS system and a handheld terminal, which solves the problem that when manual interaction is required in the existing production process, it is an external operator who produces equipment on site. Observe, measure, operate, record, and then inform the operator in the central control room remotely through the walkie-talkie, and then the operator in the central control room enters the process data remotely informed by the external operator into the DCS control system through the control system client on the computer , resulting in high labor costs, and there may be errors in the communication between the external operator and the operator in the central control room, resulting in deviations in the data entered into the control system. In the lightest case, the product quality is unqualified, in severe cases, the equipment is damaged, and even personnel safety occurs. accident technical issues
