Z-Park EMS v2.0 Deployment Buyoff Report

Date: 2026-04-12 Version: 2.0.0 (from 1.6.1) Customer: 中关村医疗器械园 (Z-Park) Checklist Source: 00.Principle/EMS_Deployment_Buyoff_Checklist.md v1.1

---

Changes in v2.0

1. 检修维护中心 (6.4) — Full maintenance module: 3-type work orders, asset management, warehouse, work plans, billing
2. AI智能分析 — LLM-powered diagnostics via StepFun/ZhipuAI APIs
3. AI模型配置 — Settings UI for model provider, temperature, prompts
4. Station Power Fix — Use API station total directly instead of inverter-level computation

---

Phase 1: Infrastructure (N/A — local dev, no backend running)

#	Check	Result	Notes
1.1	PostgreSQL running	N/A	Verify on deploy
1.2	Redis running	N/A	Verify on deploy
1.3	Migrations at head	[WARNING]	009 + 010 created, need alembic upgrade head on deploy
1.4	Seed data loaded	[WARNING]	scripts/seed_maintenance.py ready, run on deploy
1.5	Admin user exists	N/A	Verify on deploy

---

Phase 2: Backend API

#	Check	Result	Notes
2.1-2.11	Existing endpoints	N/A	No backend running — verify on deploy
2.12	[x] Python syntax — ALL 101 files	PASS	ast.parse() on every .py file
2.13	[x] New routers registered	PASS	assets, warehouse, work_plans, billing in router.py
2.14	[x] Migration chain intact	PASS	006→007→008→009→010 verified
2.15	[x] API key masking	PASS	_mask_key() in settings.py

---

Phase 3.5: Data Pipeline & Accuracy

#	Check	Result	Notes
3.5.1	[x] Station power uses API total	PASS	data_type="station_power" from curr_power
3.5.2	[x] Fallback to legacy dedup	PASS	Group-by name prefix if no station_power
3.5.3	[x] No double-counting	PASS	_station_collected tracker + seen_powers dedup
3.5.4	[x] No simple sum-all	PASS	No sum(d.value pattern found
3.5.5	[x] Collector stores station_power	PASS	New data_type alongside existing "power"
3.5.6	[ ] Validate script passes	N/A	Need running backend — run on deploy

Power Accuracy Fix Detail

Before (v1.6.1)	After (v2.0)
Dashboard computed pv_power by grouping inverter "power" readings by device name prefix (AP1/AP2), taking MAX per group	Dashboard reads "station_power" directly from API station summary (curr_power), falling back to legacy method
Timing-dependent — stale readings caused up to -188.8 kW gap	Exact match with iSolarCloud — both read same getPowerStationList.curr_power

Deployment Steps

# 1. On server: pull latest
cd /path/to/zpark-ems && git pull

# 2. Install new Python dependency
pip install openai

# 3. Run migrations
cd core/backend && alembic upgrade head

# 4. Seed maintenance data
python ../../scripts/seed_maintenance.py

# 5. Restart backend
docker compose restart backend
# or: systemctl restart zpark-ems

# 6. Verify
curl http://localhost:8000/api/v1/version
# Should show project_version: "2.0.0"
