《GB/T 39478-2020停车服务移动机器人通用技术条件》由TC591（全国机器人标准化技术委员会）、全国特种作业机器人标准化工作组联合归口，主管部门为中国机械工业联合会。
Introduction
Interpretation of the core content of the standard
This standard systematically specifies the technical requirements for three types of parking service mobile robots for the first time: comb type, car-carrying plate type and grip-lifting tire type. In terms of technological evolution, this standard integrates the dual technical systems of GB/T20721 automatic guided vehicle standard and GB/T26559 mechanical parking equipment standard.
Comparison of key technical indicators
| Performance parameters | Standard requirements | Test methods | Industry advanced level |
|---|---|---|---|
| Navigation accuracy | ±20mm | 5m track column test method | ±15mm |
| Positioning accuracy | ±10mm | Four-point round-trip positioning test | ±5mm |
| Operating speed | ≥1m/s | 5m uniform speed segment timing method | 1.5m/s |
| Safety distance | ＞50mm | Obstacle trigger test | 100mm |
Key points for implementing safety requirements
Dual-mode protection system: Article 6.1 of the standard innovatively proposes the parallel requirements of contact and non-contact protection. Taking a smart garage project in Shenzhen as an example, its gripping and lifting tire robot adopts a dual protection design of laser radar (detection distance 3m) + rubber buffer (buffer stroke 100mm), which perfectly meets the standard requirements.
Anti-overlap detection: For the parking space status detection required by Article 6.2 of the standard, it is recommended to use a combination of 3D laser scanning (accuracy ±5mm) and weight sensor (sensitivity ±2kg) in actual implementation to effectively avoid misjudgment.
Key points of test and certification
1. Navigation accuracy test: Special attention should be paid to the ground flatness requirement (≤3mm/m). It is recommended to lay epoxy floor on the concrete base surface.
2. Load test: The 6:4 front and rear axle load ratio required by Article 8.1.1 of the standard should be monitored in real time by a dynamic weighing system.
3. Environmental adaptability: The antifreeze measures of the hydraulic system need to be verified during the -10℃ low temperature test, and the battery temperature needs to be monitored during the 45℃ high temperature test.
Industry application suggestions
1. New project: It is recommended to give priority to comb-tooth robot (space utilization increased by 40%).
2. Renovation project: Car-carrying plate robots are more compatible with traditional garages
3. Operation and maintenance guarantee: Establish an annual type inspection system based on Article 9.2 of the standard, focusing on monitoring the attenuation of the navigation system
