What are the design documents for the instrument major?

Instrument professional design documents usually include the following content: 1. P&ID diagram: That is, process and instrumentation diagrams are used to represent system processes and installation locations of instrumentation controls. 2. Instrument and equipment list: List the name, model, specifications and other information of the instrument equipment. 3. Interlocking logic diagram: Used to represent the logical relationships of control systems, such as switches, valves, etc. 4. Interlock table: List the type, location, function and other information of each element in the interlocking system. 5. Alarm list: List the type, location, function and other information of each element in the alarm system. 6. Specifications: Detailed specifications and requirements for instrumentation equipment. 7. I/O table: Includes connections and configurations for digital input/output and analog input/output ports. Documents issued by formal design institutes should be complete and readable, including all the above design documents. At the same time, other types of documents need to be provided according to project needs, such as on-site construction drawings, assembly drawings, etc. The directory will vary depending on the requirements of the company or project, but will generally contain the files listed above. -

Each design institute has its own design document regulations, which are generally higher than the requirements of HG/T 20638.

You're welcome, you can continue to ask me any questions. -

You're welcome, and if you have any questions, please feel free to ask. -

Comprehensive and well-founded, thank you! If we really follow this standard, then what our design institute will issue will be too little...

Yes, according to this standard, the design institute needs to output relatively many files. However, in actual operation, the specific requirements of each project will be different. Some files may not be needed due to project characteristics, some files may need to be added based on project needs, and some files can be merged or simplified. At the same time, the design institute also needs to adjust and optimize according to customer requirements and specific project conditions. On this basis, the design institute can ensure the integrity and reliability of the output files through scientific and reasonable processes and management to ensure the smooth progress of the project. -

The recommended standards shouldn’t be the minimum requirements, right?

Yes, the output of design documents should be based on the actual needs of the project. These standards are only recommended reference standards, not minimum requirements. Therefore, in actual operation, the design institute should determine the specific design documents based on specific project needs, customer requirements and relevant specifications. At the same time, design institutes should focus on improving their own design and management levels to ensure that the quality of output design documents meets project quality requirements to meet the actual needs of customers. -
