Introduction
1. Introduction
GB/T26804.7—2017 "Industrial Control Computer System Functional Module Template Part 7: General Technical Conditions and Evaluation Methods for Video Acquisition Modules" is a standard formulated for video acquisition modules in industrial automation systems, aiming to regulate their design, manufacturing and acceptance processes. This standard covers the classification, technical requirements, test methods and inspection rules of video acquisition modules, providing important guidance for the development and application of related products.
2. Comparison of standard frameworks
| Standard dimensions | Classification basis | Technical requirements | Test methods |
|---|---|---|---|
| Video acquisition module classification | Purpose, interface type, signal source, compression method, installation method | Different categories must meet specific performance indicators | Conduct corresponding tests and verifications respectively |
| Environmental adaptability requirements | Temperature, humidity, vibration, shock, etc. | Must meet GB/T17214 series standards | Conduct environmental tests according to conditions |
| Electromagnetic compatibility requirements | Anti-interference capability, radio frequency radiation, etc. | Comply with GB/T9254 and GB/T17626 series standards | Carry out radio disturbance limit test and immunity test |
3. Technical requirements analysis
The technical requirements of the video acquisition module mainly cover the following aspects:
- Basic requirements: including bus interface, video signal type, resolution, image format, etc.
- Structural dimensions and appearance: must comply with product standards to ensure reliable connection and installation.
- Environmental adaptability: such as temperature range, humidity conditions and mechanical vibration resistance.
- Electromagnetic compatibility: must pass radio disturbance limit test and immunity test.
- Operational reliability: including continuous operation capability and mean time to repair (MTTR).
4. Implementation recommendations
In order to ensure that the video acquisition module complies with the GB/T26804.7—2017 standard, the following measures are recommended:
Case analysis: Application in an industrial automation system
When selecting a video acquisition module, its classification and performance indicators must be determined based on the specific application scenario. For example, in a high temperature and high humidity environment, a module with a wide temperature characteristic should be selected, and its adaptability should be verified through vibration and shock tests.
Summary: GB/T26804.7—2017 provides comprehensive guidance for the design and application of video acquisition modules. During implementation, it is necessary to select appropriate classifications and technical requirements based on actual needs, and conduct tests and verifications in strict accordance with the standard.
