AI资产管理系统与ERP对接API规范 v2.3
文档说明
| 属性 | 值 |
|---|---|
| 适用系统 | SAP S4HANA/Oracle EBS/用友U8 |
| 协议版本 | HTTPS/1.1 |
| 数据标准 | ISO 8000-8:2023 |
| 安全等级 | PCI DSS Level 1 |
一、认证与授权机制
1.1 OAuth 2.0流程
1.2 请求头示例
import requestsheaders = {"Authorization": "Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6...","X-Api-Version": "2.3","X-Org-Code": "UAT_AI_FACTORY","X-Request-ID": "7e5353c0-9a7a-48aa-8dd8-d2d168328c10"
}
二、核心数据模型
2.1 资产主数据映射表
| ERP字段 | AI系统字段 | 转换规则 |
|---|---|---|
| ANLKL | asset_category | 根据ISO 55000标准重映射 |
| AKTIV | purchase_value | 按财政年度汇率转换USD |
| ZUJHR | depreciation | 双倍余额递减法重新计算 |
| HERST | manufacturer | 调用DeepSeek供应商清洗接口 |
2.2 实时数据流结构
{"asset_id": "EQUIP-2024-089","sensors": [{"type": "vibration","value": 7.89,"unit": "mm/s²","timestamp": "2024-03-20T14:23:18Z"}],"maintenance_records": [{"work_order": "WO-202403201","cost": {"parts": 1200, "labor": 800},"downtime": "PT2H30M"}]
}
三、核心接口设计
3.1 资产全量同步接口
Endpoint
POST /api/v2/assets/sync
请求示例
curl -X POST "https://api.aims.com/v2/assets/sync" \-H "Content-Type: application/json" \-d '{"erp_system": "SAP_S4HANA","sync_mode": "FULL","currency": "CNY","start_date": "2024-01-01"}'
响应处理
// 使用指数退避策略的重试机制
const retryPolicy = {maxAttempts: 5,backoff: {initialDelay: 1000,multiplier: 2},retryOn: [502, 503, 504]
};
3.2 智能预测接口
Endpoint
POST /api/v2/predictions
DeepSeek集成示例
from deepseek_enterprise import AssetPredictordef predict_failure(asset_data):predictor = AssetPredictor(model_id="deepseek-industrial-v3",erp_conn=ERPConnection())return predictor.analyze(sensor_data=asset_data['sensors'],maintenance_history=asset_data['records']).to_dict()# 输出示例
{"asset_id": "EQUIP-2024-089","predicted_failure": {"failure_type": "bearing_wear","probability": 0.934,"recommended_action": {"maintenance_type": "preventive","deadline": "2024-04-15","required_parts": ["Bearing-8890", "Lubricant-A2"]}}
}
四、错误处理规范
4.1 标准错误代码表
| 代码 | 含义 | 处理建议 |
|---|---|---|
| 42901 | 资产分类映射失败 | 检查ISO 55000对照表 |
| 50302 | 预测模型超载 | 实施请求排队机制 |
| 60031 | 多ERP系统数据冲突 | 调用冲突解决接口 |
| 80022 | 安全策略拦截 | 检查X-Org-Code白名单 |
4.2 错误响应体结构
<ErrorResponse><Code>50302</Code><Message>Model serving overloaded</Message><RetryAfter>300</RetryAfter><SuggestedAction>enable_fallback_mode</SuggestedAction><RequestID>7e5353c0-...328c10</RequestID>
</ErrorResponse>
五、安全审计规范
5.1 数据脱敏规则
// 敏感字段处理类
public class DataMasker {public static String maskFinancial(String value) {return value.replaceAll("\\d(?=\\d{4})", "*"); }public static String maskAssetID(String assetId) {return "AI-" + assetId.substring(0,4) + "****";}
}
5.2 审计日志格式
2024-03-20T14:23:18Z | WARNING | ERP_SYNC | UAT_AI_FACTORY |
User: ai_engineer_03 | IP: 192.168.10.45 |
Action: asset_update | Result: partial_failure |
AffectedRecords: 23/150 | Duration: 4.7s
六、部署与监控
6.1 性能基准指标
| 场景 | QPS | P99延迟 | 容错率 |
|---|---|---|---|
| 资产元数据同步 | 250 | 800ms | 99.95% |
| 实时预测请求 | 180 | 1.2s | 99.9% |
| 批量历史数据分析 | 75 | 3.5s | 99.8% |
6.2 监控指标采集
# HELP api_request_total Total API requests
# TYPE api_request_total counter
api_request_total{method="POST",handler="/predict",status="200"} 892# HELP prediction_latency_seconds Prediction service latency
# TYPE prediction_latency_seconds histogram
prediction_latency_seconds_bucket{le="0.5"} 423
prediction_latency_seconds_bucket{le="1"} 785
七、扩展与定制
7.1 插件开发规范
interface ERPAdapterPlugin {connect(config: ERPConfig): Promise<void>;extractAssets(filter: AssetFilter): Promise<Asset[]>;writeBack(results: PredictionResult[]): Promise<WriteResult>;
}class SAPPlugin implements ERPAdapterPlugin {// 实现SAP特定协议逻辑private sapRFC = new SAPRFC();
}
7.2 多ERP联邦查询
-- 跨系统资产联合查询示例
SELECT a.asset_id,a.current_value,p.predicted_risk,erp_system
FROM (SELECT * FROM sap_assetsUNION ALLSELECT * FROM oracle_assets
) a
JOIN predictions p ON a.asset_id = p.asset_id
WHERE p.risk_level > 0.8;
