Introduction
Analysis of Standard Technology Evolution
| Version | Main Changes | Technological Advancement |
|---|---|---|
| 2011 Edition | Establishment of Basic Framework | Conventional Automation Control |
| 2020 Edition | Addition of 12 new technical requirements such as flammable/toxic gas detection, fire control, and network security | Intelligence + Safety Integrity Level (SIL) certification |
Technical Requirements for Core Instruments
Temperature Measurement Instruments
- ≤300℃, use Pt100 B-grade thermal resistor
- ＞300℃, use K/E-type armored thermocouple
- Switch setting error ≤1%
Pressure transmitter
- Intelligent accuracy ≥0.1 level
- Capillary pressure measurement is preferred for crude oil pipelines
Key points for the implementation of safety control systems
| System type | Key indicators | Maintenance cycle |
|---|---|---|
| Combustible gas detection | Response time ≤ 60s (diffusion type) | Quarterly calibration |
| Safety Instrument (SIS) | SIL certified controller | Annual functional test |
Typical case: Natural gas pipeline stations need to be equipped with dual redundant UPS power supplies, with a backup time ≥ 1.5 hours
SCADA system operation and maintenance specifications
- Screen refresh time < 2 seconds
- Dual-machine hot standby switching without disturbance
- Strictly implement three-level permission management (browsing/operation/system)
- Prohibit physical connection to the office network
Management indicator system
| Indicators | Calculation formula | Meeting standard value |
|---|---|---|
| Equipment utilization rate | ∑(single unit in use days)/(total number of units × number of days in a month) | ≥98% |
| System integrity rate | ∑(single unit in use days)/(total number of units × number of days in a month) | ≥98% |
