Introduction
GB/T 36896.1—2018 Lightweight cable-controlled underwater robot Part 1 Standard Overview
This standard specifies the classification, technical requirements, test methods and inspection rules for lightweight cable-controlled underwater robots, and is applicable to observation and operation in the marine underwater environment.
Comparison table of standard frameworks
| Dimension | Scope | Classification | Test method |
|---|---|---|---|
| Applicable scenarios | Marine underwater environment observation and operation, reference for underwater robots in rivers and lakes | - Observation type: mainly underwater camera- Operation type: with manipulator device or other operation tools | Maximum still water speed, total bollard thrust, load capacity and other performance index tests |
| Core requirements | Rated working water depth is not less than $100~\mathrm{m}$ (observation type) and $300~\mathrm{m}$ (operation type) | - Underwater part: main structure, buoyancy components, etc.- Surface part: surface control unit, launching and retracting system, etc. | Communication bandwidth is not less than $50~\mathrm{MHz}$, and the bit error rate is not more than $10^{-10}$ |
| Technological evolution | From the early deep-water observation equipment to the ROV system with precise control and diversified operation capabilities | - Observation type: real-time monitoring- Operation type: manipulator and hydraulic system cooperate to complete complex tasks | Electromagnetic compatibility test, environmental adaptability test (vibration, salt spray, etc.) |
Detailed explanation of technical requirements
Steady-state error refers to the deviation between the steady-state value actually achieved by the system and the control instruction value. In the depth and height control of underwater robots, this parameter directly affects their operating accuracy. For example, when the rated working depth is $300~\mathrm{m}$, the depth control accuracy level requires that the error ratio should not exceed level 4 ($D \leq 0.1$) in Table 2.
Key indicators of communication system
- Umbilical cable communication bandwidth: not less than $50~\mathrm{MHz}$
- Bit error rate: not more than $10^{-10}$
- Fiber optic cable test method: SJ2737 "Fiber optic cable bandwidth measurement method"
Implementation suggestions
- Procurement stage: Select observation or operation type underwater robots according to actual needs, focusing on load capacity, control accuracy and communication performance.
- Pre-use training: Operators should be familiar with the equipment structure and functions and master basic remote control operation skills.
- Daily maintenance: Regularly check the umbilical cable connection status, test the insulation resistance and grounding performance to ensure safe operation.
- Environmental adaptability verification: Test in different water depths and salinity environments to confirm that the equipment meets the working requirements.
