Motherboard machines (主板机) are Android boards without phone shells — the professional default for dense farms. Full-phone racks still exist but carry higher space, power, and battery risks.
Motherboard machine advantages
- Higher density per rack unit; less cable clutter
- No battery swelling — boards run from centralized PSU
- Easier batch maintenance and swap-out of failed nodes
- Designed for 24/7 fleet software and LAN deployment
Full smartphone racks
- Familiar form factor; sometimes required for niche sensor tests
- Higher cost per slot, larger footprint, more manual handling
- Battery aging and heat in enclosed frames
What Huicheng ships
Standard integrated chassis with 20 Android boards + control board, USB+LAN, same-site real SIM OTP. Not empty USB phone-holder boxes.
主板机是无外壳 Android 板卡集群 — 高密度农场的专业默认方案。整机架仍有人用，但占地、供电与电池风险更高。
主板机优势
- 单位机架密度高、线缆更少
- 无电池膨胀 — 集中供电
- 批量维护、故障节点更换更方便
- 面向 7×24 群控与 LAN 部署
完整手机机架
- 形态熟悉；少数传感器测试可能仍需真机
- 单槽成本高、占地大、人工操作多
- 封闭式框架内电池老化与发热
汇诚产品形态
标准集成机箱含 20 块 Android 主板+中控，USB+LAN，同站真实 SIM OTP — 非空 USB 手机支架箱。
